    DB:4.47:Best Situation That Describe Difference Between Interface And Abstract c7




    Hi, Please tell me the best example or situation where we should choose interface or abstract class?

    DB:4.47:Best Situation That Describe Difference Between Interface And Abstract c7

    Smiley,
    It is the same as about apples and computers.
    An Interface is a contract, it describes what a class should contain to implement it (and can than be used to to get those members of a class whichfulfillthe contract) but an interface contains no actual implementation.
    An Abstract Class is a class itself which can be (only) inherited used as base for another class, the members and properties of a base class can be used likewise the inheriting class.
    Because of above can an Abstract Class implement an Interface, however an Interface cannot implement an Abstract class.

    Success

    DB:2.99:Difference Between Bdc And Interface j8


    Hi Vijay,

    BDC can also be known as conversion.

    Difference between Conversion and interface

    The words were chosen for what they mean. A conversion means data that is converted from one format to another format and from one system to another. So when you first implement SAP, you are actually replacing some of your legacy systems, but you are not completely trashing the data. You still need some of that data from the systems that are being replaced. So you pull the data out of your legacy systems and put them on some files. You then want to load that data into your new SAP system. That is when you write some programs which will read that data and load it into SAP. Imagine you had a home grown purchasing system. You are now replacing all that with SAP. But until SAP goes live, you want to keep using your home grown purchasing system. So during go live, you want to transfer the POs from your legacy system to SAP. Now a PO in your legacy system may not have the same fields as a PO in SAP. So you convert the data.

    Interfacing is connecting two or more different entities. In our case, it is connecting one or more systems with SAP. Now extending our previous example, you are replacing some legacy applications but there are some applications that you don't want to replace yet. You need to somehow pass data back and forth between SAP and these remaining systems. Data may be going one way or the other way or both ways. You will still need to do some data transformations/translations etc to make the data understandable to the receiving system. This will continue as long as you want to keep the systems running alongside SAP.

    In short, conversions are written to load data into SAP onetime. These are typically file based.

    Interfaces are written to exchange/update/send/receive data between SAP and other systems on an ongoing basis. These can be in many forms, file based, idoc based, real time(business connector, XI etc are useful in this), xml, and the list goes on.

    Hope this resolves your query.

    Reward all the helpful answers.

    Hi,
    Can any one pls define that what is exactly difference between an Abstract Class and an Interface? Also I'll appreciate if some one can tell me that what we should prefer to use and why.
    Waiting for reply,
    Pranav

    DB:2.79:Difference Between Abstract Class And An Interface 3z

    Hm, it shows some uses but it (and it's predecessor article) actually don't tell what an abstract class or an interface is (or I overlooked it :-)

    Abstract class
    An abstract class is a class which can be declared and used to derive from, but which is not possible to instantiate.

    Like Animal - there is no animal, but there are Goldfish or Cat. Thus you want no Animal objects roaming your heap but only Goldfish and Cat instances. Still it makes sense to bundle the common features in Animal, and distribute them per inheritance.

    Interface
    While a class allows to group functions and variables into a unit, an interface only allows to group functions.
    Otherwise it is the same, thus can be derived from.

    However it makes no sense to create different instances of this, because you can't seperate them, there is no variable which would hold different state information that could be used for a comparison with nonequal result.

    Java offers the multiple inheritance from interfaces only, not from classes.
    This is a simplification chosen by the language designers to keep the implementation algorithms for the tools, the VM, the memory layout of the VM and perhaps the semantics complexity simple.
    (Java was intended for remote controls and other embedded devices).

    Why is this simpler?
    If A inherits from B and A inherits from C as well.
    Plus B inherits from D, plus C inherits from D,
    then we have no longer a tree/directed acyclic graph,
    but the more general case of a directed graph.

    This makes algorithms more complicated (tree walk is easier than graph walk, where you have keep track of cycles).

    Further instantiation make more trouble.
    An instance of A would contain two instances of D, one along the path A-B-D, and one along the path A-C-D.
    Thus if B,C,D were classes with variables, B-D's variables might be different from C-D's.
    This makes access semantics and storage much more complex.

    Java simplified this problem by avoiding it by just allowing interfaces for B, C, D.
    Calling A-B-D-f() is the same as calling A-C-D-f().

    Marc

    GRE (GenericRouteEncapsulation) and IPIP (IP in IP) are protocols that you use to establish the tunnel. No need to say that it the settings must match on both ends of the tunnel. The choice for a specific protocol may vary, depending on the properties of the network between the tunnel endpoints.

    DB:2.66:Available Bandwidth In Show Interface cm



    HI

    What does 'available bandwidth' describe in a 'show interface'?

    Best regards

    Roberto

    DB:2.66:Available Bandwidth In Show Interface cm


    By default the available bandwith is the 75% bandwith of the Bandwidth configured in the interface.That is if your interface bandwidth is 1.544Mbps , Your available bandwith will be 1.544 x 0.75 = 1.158

    By default weighted fair queuing is applied to interface for input and output packets. In case if you configure for QOS in the interface, the default value of available bandwidth is taken into account for the queing mechanism (Priority, custom queueing) you are configuring. This is done because of mission critical mechanisms (like keepalive, routing updates) not to be affected.

    Suppose you want to configure QOS for voice traffic using Priority queuing and the bandwidth configured is 1.544 Mbps, You can use upto 75% of the availble bandwidth that is 1.158 Mbps for the voice tarffic.

    To modify the Available bandwith use the command : max-reserved-bandwidth xx

    xx - % of bandwidth say 90 for 90%

    And you can view the modified Availbale bandwidth in Show interface serial

    value since any data that can be passed in to a create() method can just as easily be passed in to
    a special initialization method.

    For these reasons, Home interfaces are not part of the EJB 3.0 Simplified API. References to

    Hi,

    Am not sure why you are using a bpm here.

    Anyways, in this scenario, you would need to use 3 message interfaces.

    1 inbound async interface (for the file system)

    2 abstract async interface w.r.t the bpm.

    1 message mapping, to transform the idoc structure to file structure.

    And hence,1 interface mapping.

    In the configuration, you need to configure the follwing:

    2 receiver determinations.

    (1 receiver is the BPM, sender being the r/3 system and the other receiver is the File, sender being the BPM)

    2 interface determinations.

    iWhat is the difference between Standard and Extended Reciever and interface determinations in Xi configuration?/i

    Standard receiver determination is used when we need to decide upon a receiver based on a condition.

    When we need to send the same message to multiple receivers based on a single condition, we may have to use enhanced receiver determination.

    In enhanced receiver deter. we need to specify a IM that does the job of finding the receivers dynamically.

    1.The variable defined inside an interface is public, static and final means it's basically a constant,But in case of abstract class you can hide the variable in the implementation class means you can change the value of the variable.

    One very important thing about the these two feature is when to use what?
    Ans:If a group of object is having some common property such that they are not going to be changed over a period then create an Abstract class out of that property.But if only some object is having a common property but not all then create an interface out of that property and implement all that property in Subclass.

    Thanks.

    any one can please tell me Difference between
    abstract class and interface. From a typing perspecitive there's no difference (you can declare variables of both). The only difference in principle is that an abstract class also can have concrete methods so it allows you ti inherit implementation along with the type. You can only inherit from one class but from as many interfaces you whish.

    Which one is best ?The short answer is that interface is best.

    According to the 7.0 command reference, Cisco no longer recommends using the alias command:

    "To manually translate an address and perform DNS reply modification, use the alias command in global configuration mode. To remove an alias command, use the no form of this command. This command functionality has been replaced by outside NAT commands, including the nat and static commands with the dns keyword. We recommend that you use outside NAT instead of the alias command."

    DB:2.54:Label Space j1



    Hi

    can anyone describe the difference between per interface and per platform label space ?

    Thansk in advance

    Thomas

    DB:2.54:Label Space j1


    Hello Thomas,

    in frame-based MPLS on interfaces using frames (PPP, ethernet, frame-relay, etc.) LDP per default uses per platform label space. This means, that the Label Forwarding Information Base (LFIB) will contain one label per destination network in the IP routing table. It does not matter on which MPLS enabled interface a labeled packet arrives - it will have the same label for a network.

    In other words: with IP routing the FIB is used for every IP enabled interface. It does not matter on which interface an IP packet is received.

    With label switching in frame-based MPLS the LFIB is used for every MPLS enabled interface. It does not matter on which interface a labeled packet is received.

    Now there is a difference once you use cell-based MPLS. Here ATM cells respectively VPI/VCI are used for forwarding. The "label" is a VPI/VCI value. As in ATM VPI/VCI only have per interface significance, one needs a per interface label space (VPI/VCI). For a destination network the same label can - typically - not be used on different interfaces.

    Per-platform label space is denoted by :0, whereas per interface label spaces are denoted by :1, :2, ...

    The IP is the same in all cases and can be configured through "mpls ldp router-id [force]".

    Hope this helps! Please rate all posts.

    Hi Ahmad

    Multilink interfaces are used to have a single logical interface bundle in which different physical interface will be a member.

    We use multilink interface to get a single logical interface with high bandwidth capacity.

    instead of having different physical link with less bandwidth capacities.

    if its a simple point to point link between your locations and without any routing protocols better prefer multilink interface to have proper load sharing between the links..

    Interface Programs - These program will be executed

    What is the difference between Interface and Conversion

    DB:2.53:Interface df


    Hi,

    Conversion means data that is converted from one format to another format and from one system to another. So when you first implement SAP, you are actually replacing some of your legacy systems, but you are not completely trashing the data. You still need some of that data from the systems that are being replaced. So you pull the data out of your legacy systems and put them on some files. You then want to load that data into your new SAP system. That is when you write some programs which will read that data and load it into SAP. Imagine you had a home grown purchasing system. You are now replacing all that with SAP. But until SAP goes live, you want to keep using your home grown purchasing system. So during go live, you want to transfer the POs from your legacy system to SAP. Now a PO in your legacy system may not have the same fields as a PO in SAP. So you convert the data.

    Interfacing is connecting two or more different entities. In our case, it is connecting one or more systems with SAP. Now extending our previous example, you are replacing some legacy applications but there are some applications that you don't want to replace yet. You need to somehow pass data back and forth between SAP and these remaining systems. Data may be going one way or the other way or both ways. You will still need to do some data transformations/translations etc to make the data understandable to the receiving system. This will continue as long as you want to keep the systems running alongside SAP.

    In short, conversions are written to load data into SAP onetime. These are typically file based.

    Interfaces are written to exchange/update/send/receive data between SAP and other systems on an ongoing basis. These can be in many forms, file based, idoc based, real time(business connector, XI etc are useful in this), XML, and the list goes on.

    is that right?

    best regard

    DB:2.52:Can Anyone Tell Me The Difference In Performance Between Css Url Switching zc


    It looks like the primary question here is performance, in which case:Performance is not an issue, so long is it is sufficient. In the case of CSS 11000 and Alteon, performance fall within the same order of magnitude (supporting web sites with several billion hits per day.) F5 does not have sufficient performance, due to platform and OS limitations (I’ve heard as low as 50 connections per second in complex configurations). The Cisco CSM posts up over 10x the performance at 200k flows/second.

    Typically the primary concern is features, then CSS 11000 switches lead with a wide and flexible array of features that are not only helpful to network and web administrators, but well integrated too. CSS 11000 switches offer configuration through CLI, Web GUI, and XML. CSS 11000 collects statistics that can be exported to non-Cisco applications for billing and management.

    The CSS11000 also supports URL load balancing and HTTP header balancing within one content rule, with complex matching. Further, it supports user agent, pragma/no-cache, host field, cookie field, language field, accept, accept charset, accept-encoding, and Connection within the http header field.

    In addition, the CSS11000 matches up to 128 bytes with support of wildcards anywhere within the string.On the other hand, Nortel (Alteon) - HTTP header load balancing is not supported on the same VIP as URL load balancing. Eg. This means that a simulated WAP user cannot be directed to a server while load balancing "normal" browsers to their servers based on URL without using two separate VIPs. Only ONE http header load balance is supported on the entire switch. This limits you to either User Agent (WAP, Netscape, IE, Palm, etc), OR pragma/no cache (do not send the user to cache, allow (the user) to go to the origin), or Host field (allowing you to direct on domain name), or Cookie. Also, Nortel does not support the language field.

    In regards to F5, many of the performance claims are based on HTTP 1.0 requests (most web sites today are not using HTTP 1.0), Many emerging applications rely on HTTP 1.1 rather than HTTP 1.0. Also, the BIG-IP cannot spoof the connection to detect the URL, cannot do NAT on the flow, and cannot maintain states for persistent connections.

    Overall, I think CSS switches are the lowest cost to own, and most effective of all the load balancing platforms on the market.

    there are actually more methods how you can supply various external Market data - FX rates, benchmark interest rates (like LIBOR, EURIBOR, etc.), bonds prices, etc. - into the system:
    manual entry - this is the most simple method - you just choose an appropriate menu item;file interface - use SAP trans. TBDM for this purpose - can be used to upload Market data via a text file to your system. The Market data must be stored in a specific format in the text file. for more information, please see http://help.sap.com/saphelp_45b/helpdata/en/35/a7b5629af50d14e10000009b38f9b9/frameset.htm;via Spreadsheet - use SAP trans. TBEX for this purpose - can be used to upload Market data via .XLS file to your system. The data sheet of the spreadsheet from which you want to transfer the market data must correspond to a defined format. for more information, please see Market Data Transfer from Spreadsheet - Environment - SAP Library;via Datafeed - this is the most complex and most expensive choice, when your Treasury requires real-time update of Market data. for more information, please see Datafeed - Environment - SAP Library.

    as you can see, the major difference is the frequency of data update and also relevant costs of a selected choice.

    For IPSec hub/spoke VPN's, you can do:

    Site-Site Ipsec VPN using crypto maps

    Remote Client access VPN using EZVPN server (dynamic crypto maps)

    GRE+IPSec VPN with/without Routing Protocols using Crypto maps or GRE Tunnel Protection

    IPSec Virtual Tunnel Interface is a new feature that provides additinal benefits - allows multicast/Routing Protocols, can add additional features like QoS/FW etc on the tunnel interface.

    Can do all of the above 3 using VTI (static VTI using ipsec tunnel interface or Dynamic VTI using virtual-templates). So VTI is the new way f doing IPSec VPN's and think all new deployments should use this.

    Hi

    CONVERSION programs are the ones which have one time usage, usually when a legacy system is being replaced by a system like SAP, then the data has to be mapped from the legacy system to SAP system. Here the data to be converted is given on a flat file is uploaded to SAP tables mostly using LSMW only. Conversions programs are BDC,BAPI and LSMW programs in which you upload all the related tables from the flat files.Those are one time programs.

    Interface programs are those programs in which you fetch the data from the application server and process on theose data.These are helpful when you have to run any program in the backgroup when the presentation server is not working.

    INTERFACE programs are the ones which are run at regular intervals, say weekly, monthly or even daily. Here the legacy system continues to co-exist along with SAP system, the legacy system might be useful for certain functionalities but the data might have to run thru SAP transactions for complex data maintenance at regular intervals.

    DB:2.52:Whats The Real Difference Between Point-To-Point And Multipoint Int Type 9s



    Hi All,

    Does any body know the real difference between point-to-point and multipoint interface type? I just know that when you use point-to-point in frame-relay etc, you can not connect to two peers (so in frame-relay, you can just config 1 virtual-circuit). So I usually set the interface type to multipoint when I config subinterface. Because I think multipoint is better for the reason above. But is there any feature that point-to-point can do but multipoint can not? Thank You!

    Best Regards

    Teru Lei

    DB:2.52:Whats The Real Difference Between Point-To-Point And Multipoint Int Type 9s


    YES..point to point is for one PVC only while Point to multipoint is for more then one PVCs on a same interface. Also the difference is in how PVC gets learnt on p-to-multipoint interface.

    Point-to-point subinterface : With point-to-point subinterfaces, each pair of routers has its own subnet. If you put the PVC on a point-to-point subinterface, the router assumes that there is only one point-to-point PVC configured on the subinterface. Therefore, any IP packets with a destination IP address in the same subnet are forwarded on this VC. This is the simplest way to configure the mapping and is therefore the recommended method. Use the frame-relay interface-dlci command to assign a DLCI to a specified Frame Relay subinterface.

    Multipoint networks - Multipoint networks have three or more routers in the same subnet. If you put the PVC in a point-to-multipoint subinterface or in the main interface (which is multipoint by default), you need to either configure a static mapping or enable inverse Address Resolution Protocol (ARP) for dynamic mapping.

    Here is the url for more detailed explanation between those two.

    Just answer me when can a programmer use ABSTRACT CLASS when can he use INTERFACE.

    i need the situation not the theory,that are available in all java books.

    keep smiling...

    DB:2.51:Abstract Class Vs Interface ak

    Interfaces are used to allow a class to have multiple personalities. A class can implement any number of interfaces and this will allow it to be any of those types of objects. (It's almost like multiple inheratence)

    An abstract class has to be extended and you can only extend one abstract class.

    An abstract class defines a general idea of what the object is. You extend it to fill in the details.

    An interface provides a framework for expected behaviour you provide the details of that behaviour.

    DB:2.50:Difference Between Implements Thread And Ex zp


    what is the difference between extending the thread and implements the runnable interface..?

    DB:2.50:Difference Between Implements Thread And Ex zp

    Not much. One reason to prefer implementing the Runnable interface as oppossed to extending Thread is to allow your class to extend a diifferent base class if you choose to do so. Since Java supports single implementation inheritance it is always a good idea to implement Runnable as oppossed to extending Thread in case you want to extend some other class, besides Thread, now or in the future.

    Some OO purists may also claim that unless your class (that extends Thread) "is a" specialized Thread that extending Thread breaks the OO sematics of the "is a" relationship that inheritance is suppossed to represent. For instance a widget class that draws a pixel randomly on the screen that needs to be run in it's own Thread really isn't a specialized Thread class.

    ip secondary address exists, may affect IP HW switching between subnets

    within the same vlan - out of sequence packets could occur

    can somebody describe me a real network situation when these out of sequence packets could occur ? is the command just entered for protection of the MSFC2 or are there any real threats that have slipped my mind ?

    DB:2.50:Icmp Unreachables And Secondary Ip Addresses On Msfc2 a8


    As an example for a situation, when out of sequence packets can occur, using per-packet load balancing to share the traffic load across available paths to a given destination can cause out-of-sequence packets in a particular data flow. This can result in unsatisfactory data transmission for video and voice streaming.

    I guess the issue with MSFC2 ip unreachables has been documented, you could look for bugs related to the same. Removing the secondary seems to be the only option, especially if it will not be an issue to reconfigure. I don't think there is any other way to ensure that out of sequence packets will be seen with the secondary ip's configured.

    DB:2.50:What Is The Difference Between The Comparable Interface And Comparator Intf z9


    Hi,
    folks,
    give me the difference between them

    DB:2.50:What Is The Difference Between The Comparable Interface And Comparator Intf z9

    Hi,
    folks,
    give me the difference between them

    Comparable

    This interface imposes a total ordering on the objects of each class that implements it. This ordering is referred to as the class's natural ordering, and the class's compareTo method is referred to as its natural comparison method.

    Lists (and arrays) of objects that implement this interface can be sorted automatically by Collections.sort (and Arrays.sort). Objects that implement this interface can be used as keys in a sorted map or elements in a sorted set, without the need to specify a comparator.

    The natural ordering for a class C is said to be consistent with equals if and only if (e1.compareTo((Object)e2) == 0) has the same boolean value as e1.equals((Object)e2) for every e1 and e2 of class C. Note that null is not an instance of any class, and e.compareTo(null) should throw a NullPointerException even though e.equals(null) returns false.

    It is strongly recommended (though not required) that natural orderings be consistent with equals. This is so because sorted sets (and sorted maps) without explicit comparators behave "strangely" when they are used with elements (or keys) whose natural ordering is inconsistent with equals. In particular, such a sorted set (or sorted map) violates the general contract for set (or map), which is defined in terms of the equals method.

    For example, if one adds two keys a and b such that (!a.equals((Object)b) a.compareTo((Object)b) == 0) to a sorted set that does not use an explicit comparator, the second add operation returns false (and the size of the sorted set does not increase) because a and b are equivalent from the sorted set's perspective.

    Virtually all Java core classes that implement comparable have natural orderings that are consistent with equals. One exception is java.math.BigDecimal, whose natural ordering equates BigDecimal objects with equal values and different precisions (such as 4.0 and 4.00).

    For the mathematically inclined, the relation that defines the natural ordering on a given class C is:

    {(x, y) such that x.compareTo((Object)y) = 0}.

    The quotient for this total order is:

    {(x, y) such that x.compareTo((Object)y) == 0}.

    It follows immediately from the contract for compareTo that the quotient is an equivalence relation on C, and that the natural ordering is a total order on C. When we say that a class's natural ordering is consistent with equals, we mean that the quotient for the natural ordering is the equivalence relation defined by the class's equals(Object) method:

    {(x, y) such that x.equals((Object)y)}.

    ------------------------------------------------------------------------------------------------

    Comparator

    A comparison function, which imposes a total ordering on some collection of objects. Comparators can be passed to a sort method (such as Collections.sort) to allow precise control over the sort order. Comparators can also be used to control the order of certain data structures (such as TreeSet or TreeMap).

    The ordering imposed by a Comparator c on a set of elements S is said to be consistent with equals if and only if (compare((Object)e1, (Object)e2)==0) has the same boolean value as e1.equals((Object)e2) for every e1 and e2 in S.

    Caution should be exercised when using a comparator capable of imposing an ordering inconsistent with equals to order a sorted set (or sorted map). Suppose a sorted set (or sorted map) with an explicit Comparator c is used with elements (or keys) drawn from a set S. If the ordering imposed by c on S is inconsistent with equals, the sorted set (or sorted map) will behave "strangely." In particular the sorted set (or sorted map) will violate the general contract for set (or map), which is defined in terms of equals.

    For example, if one adds two keys a and b such that (a.equals((Object)b) c.compare((Object)a, (Object)b) != 0) to a sorted set with comparator c, the second add operation will return false (and the size of the sorted set will not increase) because a and b are equivalent from the sorted set's perspective.

    Note: It is generally a good idea for comparators to implement java.io.Serializable, as they may be used as ordering methods in serializable data structures (like TreeSet, TreeMap). In order for the data structure to serialize successfully, the comparator (if provided) must implement Serializable.

    For the mathematically inclined, the relation that defines the total order that a given comparator c imposes on a given set of objects S is:

    {(x, y) such that c.compare((Object)x, (Object)y) = 0}.

    The quotient for this total order is:

    {(x, y) such that c.compare((Object)x, (Object)y) == 0}.

    It follows immediately from the contract for compare that the quotient is an equivalence relation on S, and that the natural ordering is a total order on S. When we say that the ordering imposed by c on S is consistent with equals, we mean that the quotient for the natural ordering is the equivalence relation defined by the objects' equals(Object) method(s):

    {(x, y) such that x.equals((Object)y)}.

    DB:2.49:Port, Vsan And Zone Mapping mj


    Hi Igor,

    You should use the "show flogi database"  to see who is logged into the fabric on this switch.

    If you have more than one switch in your fabric, then you will need to use "show fcns database" to see them

    from the other switches.

    switch# show fcns database vsan 10

    VSAN 10:

    ----------------------------------------------------------------------------------------------------------------

    FCID        TYPE  PWWN                    (VENDOR)        FC4-TYPE:FEATURE

    ----------------------------------------------------------------------------------------------------------------

    0xe80000    N     21:01:00:e0:8b:39:a9:07 (Qlogic)        scsi-fcp:init

    In the example above, this HBA is on a swtich with fcdomain "0xe8"

    If you want to find out what switch this is, use "show fcdomain domain-list vsan 10" and show "fcs ie vsan 10" or

    you can use "show topology vsan 10"

    Switch1# show topo vsan 10

    FC Topology for VSAN 10 :

    --------------------------------------------------------------------------------------------------------

           Interface         Peer Domain      Peer Interface        Peer IP Address

    ---------------------------------------------------------------------------------------------------------

                fc4/1         0xea(234)           fc1/5                   172.18.121.75

    port-channel 128   0xe8(232)           port-channel 128  172.18.121.44

    I can see that this HBA is on a switch with IP address 172.18.121.44 because the FCDOMAIN of that

    switch is 0xe8 and that is also the first byte of the FCID assigned to the HBA.

    Now if I go to that switch:

    Switch4# show flogi data

    -----------------------------------------------------------------------------------------------------------------------------------

    INTERFACE        VSAN    FCID           PORT NAME                      NODE NAME

    ------------------------------------------------------------------------------------------------------------------------------------

    fc1/29                 10        0xe80000      21:01:00:e0:8b:39:a9:07     20:01:00:e0:8b:39:a9:07

    The reason you might see more than one PWWN on a particular switch port is a feature called N-Port Virtualization.

    This allows for more than one device to log into the same port.  This is usually used in conjuction with a device like a blade center or UCS that has multiple HBAs in it. 

    Here is a white paper on N-Port virtualization:

    DB:2.49:What's The Difference Between Routing And Service Callout In Alsb? ps

    There is little difference between routing and service callout.
    Routing is symbolizes the transition of request thread to a response thread starts. (in OSB every invocation of proxy is undertaken by different request and response threads ). So by this definition, there can be only one route node in a pipeline.

    Service call out is also used for similar actions as route node , but in pipeline. So service callout can be either in request pipeline (request thread) or in response pipeline (response thread ) . So in a proxy you can have multiple ServiceCallouts but only one route node.
    There are some other slight differences.

    Thanks a lot Victor for your excellent example.

    For the moment, my Focus is on Ethernet.

    Tracking sub-interfaces would be helpful in a scenario where there are several virtual interfaces configured to connect to different networks.

    For instance, bringing down some networks for maintenance or when there's a new interconnection to be commissioned, could be taken.

    Simply shutting down the sub-interface will lead to Standby router taking over for the link in discussion.

    Since the Physical interface is up, the new link could be commissioned without any service interruption to the existing connection.

    I understand this example is quite specific.

    BAPI are RFC enabled function modules. the difference between RFc and BAPI are business objects. You create business objects and those are then registered in your BOR (Business Object Repository) which can be accessed outside the SAP system by using some other applications (Non-SAP) such as VB or JAVA. in this case u only specify the business object and its method from external system in BAPI there is no direct system call. while RFC are direct system call Some BAPIs provide basic functions and can be used for most SAP business object types. These BAPIs should be implemented the same for all business object types. Standardized BAPIs are easier to use and prevent users having to deal with a number of different BAPIs. Whenever possible, a standardized BAPI must be used in preference to an individual BAPI.

    IDOC type and IDOC. An Intermediate Document (IDOC) type represents the structure of the data associated with a message type (DEBMAS02 for message type DEBMAS Customer Master, and WMMBID02 for message type WMMBXY Goods Movements), while an IDOC is an object containing the data of a particular message type. IDOCs are data containers with intelligence built in. Each IDOC contains one and only one business object. For example, an IDOC of type SHPMNT01, message type SHPMNT, will contain data only of one Shipment Document. Generally, the architecture of an IDOC is independent of the message type by virtue of ALEs ability to redefine it for any message type.

    Could you please describe me what is difference in architecture between auditing against snapshot and against live server?

    I would guess that BL every time has to collect information from server and after that it runs audit against collected information, but time consumed by both ways are different.

    Can you please describe what is difference? If this is in docs, please send me page # :).

    Thanks

    DB:2.49:Architecture Difference Between Audit Against Live Server And Snapshot 7a


    Live audit means that it scans the master and stores that info temporarily in the DB / some cache to compare against all the targets (from what I understand).

    If the master changes every time, then you will want to use a live audit. An audit based off a snapshot will be faster, but if your master is changing every time it may make more sense to keep it as a live audit instead of re-taking a snapshot each time, and then going into the audit job to change the master to the new snapshot.

    Snapshots are best when your master is unchanging.

    HI Suresh,

    Component Controller : Each UI component has a component Controller in whose context you can store cross-view data in the context node.The context nodes defined in the component controller can be "Published" in the component interface and thus provide to other UI components.

    Interface Controller : Publishing context nodes allow users to access UI component data in read and write mode. Publishing a window as an interface view enables the embedding UI component to use visual part of an embedded UI component . Finally ,UI component events enable other UI components to be informed about a status change, these elements are provided decoratively by the Interface Controller.

    In short: Component Controller allows the data to be accessed globally, and Interface Controller makes that component to go or appear globally.

    Regards
