Difference between invoke and reply

Just got a question in my mind -
what is the difference between invoke and reply ?
I know Invoke activity lets you invoke the operation in the partners WSDL. But what reply do?

Hi,
<invoke> : An invoke activity enables you to invoke a service (identified by its partner link) and specify an operation for this service to perform.
<reply> : Generating a response for synchronous operations. A synchronous process uses a <reply> activity to respond synchronously to the caller.
To know more about BPEL primitive and structure activities, read the Oracle BPEL Process Manager Developer's Guide.
Cheers,
Abhi...

  • Difference between invoking a method using reflect.proxy and reflect.Method

    Could any one tell me the difference between invoking a method using reflection java.lang.reflect.Method and java.lang.reflect.Proxy
    using both the class, we can invoke a method at runtime
    1)
    Method mthd=cl.getMethod("methodName",parameterName);
    Integer output=(Integer)mthd.invoke(new RunMthdRef(),input);
    2)
    Proxy.newProxyInstance(super.getClass().getClassLoader(), new Class[] { adapter }, new SomeClass(this));
    Does anybody have any idea?

    The two idioms are fundamentally different. Using java.lang.reflect.Method is how we call a method on a class, using Proxy is how we intercept that method call. An exercise for you, to illustrate that they do not do the same thing: write a simple class with one method, then use java.lang.reflect.Method to invoke that method, and then use a Proxy to invoke that method

  • Difference Between BAPI and RFM

    Dear Friends,
    I have seen a few thread explaining the difference between BAPI and RFM(Remote-enabled function Modules) from functional point of view. I know that there are cases when both are available in BOR. Both can be implement using Object Oriented Technology.
    Can any tell me how they differ from techincal point of view ? OR Are they same techinically ?
    Thanks in advance,
    Rajesh

    hi,
    Remote Function Call:
    RFC is an SAP interface protocol.
    Based on CPI-C, it considerably simplifies the programming of communication processes between systems.
    RFCs enable you to call and execute predefined functions in a remote system - or even in the same system.
    RFCs manage the communication process, parameter transfer and error handling.
    http://help.sap.com/saphelp_47x200/helpdata/en/22/042860488911d189490000e829fbbd/frameset.htm.
    BAPI
    BAPI stands for Business API(Application Program Interface).
    A BAPI is remotely enabled function module
    ie it can be invoked from remote programs like standalone JAVA programs, web interface etc..
    You can make your function module remotely enabled in attributes of Function module but
    A BAPI are standard SAP function modules provided by SAP for remote access.
    Also they are part of Businees Objest Repository(BOR).
    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.

  • Differences between @EJB and @Resouce?

    Hi,
    I am confused about the differences between @EJB and @Resource?
    1.
    Can Session Beans be injected for both?
    If so what are the pro's / con's?
    2.
    Are the any difference between the type of components that cna be registered for one but not the other?
    3.
    Are they both equally usable with the ENC?
    Many thanks.

    @EJBs are 'special' resources. For example, @EJB (for a stateful session bean) results in
    1. Creation of the Stateful Session Bean,
    2. Other dependencies are injected into this newly created bean,
    3. If the bean has a @PostConstruct bean then that method is invoked (after invoking applicable interceptors)
    Hope this helps

  • Difference between RP_PROVIDE_FROM_LAST and RP-PROVIDE-FROM-LAST

    Can anyone tell me the difference between RP_PROVIDE_FROM_LAST and RP-PROVIDE-FROM-LAST?  Both the macros are same difference is with underscore(_) and hiphen(-).  Both are working fine for the functionality without any difference.  Then why there are two macros for a single functionality?

    Just providing the links are considered as link farming ( which are against the rules of the forums ), the links would be removed for the following reasons:
    1) If a link is provided( not many ) , then you must point out the explanation in it
    2) If the links were easily searchable by the OP
    3) If the links just direct you to sap documentation
    4) If the reply consists only bunch of link references.
    I think the 3rd & 4th point made your post to be deleted.
    There are no links which states the differences between these two Macro's. Mod's are doing their right job, please join them and make this forum clean

  • Difference between zero and blank values

    Is there a way for the system to determine the difference between zero and blank values. One can have a zero allowed for the 0 value to actualy be there in the KF but is there a way that a macro can be written by which we can use the differentiation between the zero ( a value) and blank (no value) in the KF
    I have tried to look for an explanation on the service.sap.com and sdn but was not able to find anything.
    Thanks in advance

    Thanks for your reply. You mentioned something about the "fixing" setting that could make the "0" displayed in the planning book. Could you elaborate?
    Also, in the post from user "APO APO" on 5/8, the author seemed to indicate they could see the "0" in the planning book, as quoted below:
    "I have already made the zero allowed arrangement for that in the planning area and can see the 0 values in the planning book but I am not being able to make the macro get the results."
    I just want to find out if there is any way the user can visually distinguish b/w the "0" and blank values. If not, it'll be very confusing to the users. I understand the macros can distinguish b/w them.
    Thanks in advance.

    See the forum FAQ
    SQL and PL/SQL FAQ
    "3. How to improve the performance of my query?"
    2)What approach you take to tune query? Do you use Hints?Hints can help.
    Even more helpful is writing the SQL efficiently (avoiding multiple scans of the same table, filtering early, using built-in rather than user-defined functions, ...), creating and using indexes, and, for large tables, partitioning.
    Table design can have a big impact on performace.
    Look for ways to do part of what you need before the query. This includes denormalizing (when appropriate), the kind of pre-digesting that often takes place in data warehouses, function-based indexes, and, starting in Oracle 11, virtual columns.
    3)Where did you tune the query and what are the issue with query?Either this question is a vague summary of the entire thread, or I don't understand it. Can you re-phrase this part?
    4)What is difference between RBO and CBO? where u use RBO and CBO.Basically, use RBO if you have Oracle 7 or earlier.

  • Difference between ProcessRequest and ProcessFormRequest

    Hi All,
    Can any body explain what is the difference between ProcessRequest and ProcessFormrequest and where and when it is used ?
    Thanks

    Maya,
    To give you a slight idea, ProcessRequest is fired before the Page renders and so any code you want to execute before the Page is shown to the user should be invoked from this place. ProcessFormRequest is fired wheenver user does some formsubmit. So in case you want to handle some event, you should put your invocation code here.
    All these are very explicitly explained in the Developer's guide. Please refer to it.
    Thanks

  • What is the difference between tkprof and explainplan

    Hi,
    what is the difference between tkprof and explainplan.

    Execution Plans and the EXPLAIN PLAN Statement
    Before the database server can execute a SQL statement, Oracle must first parse the statement and develop an execution plan. The execution plan is a task list of sorts that decomposes a potentially complex SQL operation into a series of basic data access operations. For example, a query against the dept table might have an execution plan that consists of an index lookup on the deptno index, followed by a table access by ROWID.
    The EXPLAIN PLAN statement allows you to submit a SQL statement to Oracle and have the database prepare the execution plan for the statement without actually executing it. The execution plan is made available to you in the form of rows inserted into a special table called a plan table. You may query the rows in the plan table using ordinary SELECT statements in order to see the steps of the execution plan for the statement you explained. You may keep multiple execution plans in the plan table by assigning each a unique statement_id. Or you may choose to delete the rows from the plan table after you are finished looking at the execution plan. You can also roll back an EXPLAIN PLAN statement in order to remove the execution plan from the plan table.
    The EXPLAIN PLAN statement runs very quickly, even if the statement being explained is a query that might run for hours. This is because the statement is simply parsed and its execution plan saved into the plan table. The actual statement is never executed by EXPLAIN PLAN. Along these same lines, if the statement being explained includes bind variables, the variables never need to actually be bound. The values that would be bound are not relevant since the statement is not actually executed.
    You don’t need any special system privileges in order to use the EXPLAIN PLAN statement. However, you do need to have INSERT privileges on the plan table, and you must have sufficient privileges to execute the statement you are trying to explain. The one difference is that in order to explain a statement that involves views, you must have privileges on all of the tables that make up the view. If you don’t, you’ll get an “ORA-01039: insufficient privileges on underlying objects of the view” error.
    The columns that make up the plan table are as follows:
    Name Null? Type
    STATEMENT_ID VARCHAR2(30)
    TIMESTAMP DATE
    REMARKS VARCHAR2(80)
    OPERATION VARCHAR2(30)
    OPTIONS VARCHAR2(30)
    OBJECT_NODE VARCHAR2(128)
    OBJECT_OWNER VARCHAR2(30)
    OBJECT_NAME VARCHAR2(30)
    OBJECT_INSTANCE NUMBER(38)
    OBJECT_TYPE VARCHAR2(30)
    OPTIMIZER VARCHAR2(255)
    SEARCH_COLUMNS NUMBER
    ID NUMBER(38)
    PARENT_ID NUMBER(38)
    POSITION NUMBER(38)
    COST NUMBER(38)
    CARDINALITY NUMBER(38)
    BYTES NUMBER(38)
    OTHER_TAG VARCHAR2(255)
    PARTITION_START VARCHAR2(255)
    PARTITION_STOP VARCHAR2(255)
    PARTITION_ID NUMBER(38)
    OTHER LONG
    DISTRIBUTION VARCHAR2(30)
    There are other ways to view execution plans besides issuing the EXPLAIN PLAN statement and querying the plan table. SQL*Plus can automatically display an execution plan after each statement is executed. Also, there are many GUI tools available that allow you to click on a SQL statement in the shared pool and view its execution plan. In addition, TKPROF can optionally include execution plans in its reports as well.
    Trace Files and the TKPROF Utility
    TKPROF is a utility that you invoke at the operating system level in order to analyze SQL trace files and generate reports that present the trace information in a readable form. Although the details of how you invoke TKPROF vary from one platform to the next, Oracle Corporation provides TKPROF with all releases of the database and the basic functionality is the same on all platforms.
    The term trace file may be a bit confusing. More recent releases of the database offer a product called Oracle Trace Collection Services. Also, Net8 is capable of generating trace files. SQL trace files are entirely different. SQL trace is a facility that you enable or disable for individual database sessions or for the entire instance as a whole. When SQL trace is enabled for a database session, the Oracle server process handling that session writes detailed information about all database calls and operations to a trace file. Special database events may be set in order to cause Oracle to write even more specific information—such as the values of bind variables—into the trace file.
    SQL trace files are text files that, strictly speaking, are human readable. However, they are extremely verbose, repetitive, and cryptic. For example, if an application opens a cursor and fetches 1000 rows from the cursor one row at a time, there will be over 1000 separate entries in the trace file.
    TKPROF is a program that you invoke at the operating system command prompt in order to reformat the trace file into a format that is much easier to comprehend. Each SQL statement is displayed in the report, along with counts of how many times it was parsed, executed, and fetched. CPU time, elapsed time, logical reads, physical reads, and rows processed are also reported, along with information about recursion level and misses in the library cache. TKPROF can also optionally include the execution plan for each SQL statement in the report, along with counts of how many rows were processed at each step of the execution plan.
    The SQL statements can be listed in a TKPROF report in the order of how much resource they used, if desired. Also, recursive SQL statements issued by the SYS user to manage the data dictionary can be included or excluded, and TKPROF can write SQL statements from the traced session into a spool file.
    How EXPLAIN PLAN and TKPROF Aid in the Application Tuning Process
    EXPLAIN PLAN and TKPROF are valuable tools in the tuning process. Tuning at the application level typically yields the most dramatic results, and these two tools can help with the tuning in many different ways.
    EXPLAIN PLAN and TKPROF allow you to proactively tune an application while it is in development. It is relatively easy to enable SQL trace, run an application in a test environment, run TKPROF on the trace file, and review the output to determine if application or schema changes are called for. EXPLAIN PLAN is handy for evaluating individual SQL statements.
    By reviewing execution plans, you can also validate the scalability of an application. If the database operations are dependent upon full table scans of tables that could grow quite large, then there may be scalability problems ahead. On the other hand, if large tables are accessed via selective indexes, then scalability may not be a problem.
    EXPLAIN PLAN and TKPROF may also be used in an existing production environment in order to zero in on resource intensive operations and get insights into how the code may be optimized. TKPROF can further be used to quantify the resources required by specific database operations or application functions.
    EXPLAIN PLAN is also handy for estimating resource requirements in advance. Suppose you have an ad hoc reporting request against a very large database. Running queries through EXPLAIN PLAN will let you determine in advance if the queries are feasible or if they will be resource intensive and will take unacceptably long to run.

  • What's the difference between WorkflowTask and WorkflowJob in SAP MDM API?

    Hi Support,
      Could you tell me the differences between WorkflowTask and WorkflowJob in SAP MDM API? And which can represent a workflow in Workflows tab in MDM Date Manager.
    Thanks & Regards,
    Song

    Hi Songxu,
    Workflow Task: It is the task(workflow steps like Process, Approver etc) assigned to different user during Workflow. User's  use the workflow tabs in Data Manager to view and process workflow tasks. see page 91/654 of Data Manager Guide.
    http://help.sap.com/saphelp_nwmdm71/helpdata/en/4b/72b8aaa42301bae10000000a42189b/MDMDataManager71.pdf
    Workflow Job: Each workflow is invoked as a job that can consist of multiple records that move through the steps of a workflow (how many records are involved into your Workflow) as a group while simultaneously maintaining record-level granularity. Once the job has been launched, it moves automatically from step-to-step and from user-to-user, showing up in the inbound task queue in each useru2019s Workflows tab for disposition and processing.
