How to retrieve parallel process info (aRFC)

Hi guys , I have a program that calls 2 RFC-enabled function modules and runs them in parallel. To my knowledge, each function modules is assigned with a unique task id when performing parallel processing.
My question is, how do I retrieve the information on the individual process such as task name and its duration?
say
call function 'Z_XXX' starting new task 'A' performing 'Z_FUNC' on end of task.....
and
call function 'Z_XXX' starting new task 'B' performing 'Z_FUNC' on end of task .....
then execute these functions and let it runs for a while, then how do i retrieve the task name of each process programmatically (A and B)?
sorry I'm still pretty new when it comes to ABAP
edit:-
somehow my previous question was removed along with replies

Hello,
You can use following function module to get the id of transactional processing.
CALL FUNCTION 'ID_OF_BACKGROUNDTASK'
* EXPORTING
*   DEST          = ' '
* IMPORTING
*   TID           = --> collect ID from this varaible
*   FNUM          =
and for reteriving status you can use:
CALL FUNCTION 'STATUS_OF_BACKGROUNDTASK'
EXPORTING
    tid                 =
tables
    errortab            =
* EXCEPTIONS
*   COMMUNICATION       = 1
*   RECORDED            = 2
*   ROLLBACK            = 3
*   OTHERS              = 4
IF sy-subrc <> 0.
* MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO
*         WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.
ENDIF.
Hope this helps!
Thanks,
Augustin.

How to do parallel processing with dynamic internal table

Hi All,
I need to implement parallel processing that involves dynamically created internal tables. I tried doing so using RFC function modules (using starting new task and other such methods) but didn't get success this requires RFC enabled function modules and at the same time RFC enabled function modules do not allow generic data type (STANDARD TABLE) which is needed for passing dynamic internal tables. My exact requirement is as follows:
1. I've large chunk of data in two internal tables, one of them is formed dynamically and hence it's structure is not known at the time of coding.
2. This data has to be processed together to generate another internal table, whose structure is pre-defined. But this data processing is taking very long time as the number of records are close to a million.
3. I need to divide the dynamic internal table into (say) 1000 records each and pass to a function module and submit it to run in another task. Many such tasks will be executed in parallel.
4. The function module running in parallel can insert the processed data into a database table and the main program can access it from there.
Unfortunately, due to the limitation of not allowing generic data types in RFC, I'm unable to do this. Does anyone has any idea how to implement parallel processing using dynamic internal tables in these type of conditions.
Any help will be highly appreciated.
Thanks and regards,
Ashin

How to achieve parallel processing in a single request?

Hi all,
I have a method in a Session EJB that will perform some business logic before it returns an answer to the client. The logic it will perform is to collect data from the applications database and two external systems, before sending all data to a third external system to get a response and send it back to the client. Each external system is quite slow so I would like to do all the collecting of data concurrent, parallel processing. How should I handle this? I'm not allowed to create my own threads in EJB's. Can I use MDB in some way? To the calling client this should be a synchronous call...
Greatfull for any suggestions
Cheers
Anders =)

Usually, the request is received by a component located in the web container, such as by an HTTP request (including Web Services). This component is able to start threads to allow parallel processing. Now, if for some reason the request arrives directly at EJB level and that you cannot move its receiver to web component, I think JMS is not a viable solution because you will switch to asynchronous processing and you have no way to make your EJB wait for the responses while preserving the client request (waiting implies programmatic life cycle management, which is forbidden in EJB container). Maybe a resource adapter (JCA) can bring a solution. A resource adapter acts as a datasource (a datasource is a specialization of a resource adapter) and thus it is a logical way to implement an adapter to an external, eventually non-J2EE, resource, as the name implies :) But I don't have enough knowledge in JCA to be sure of this.
Hope it helps.

How to monitor parallel processing

Hi All,
I have 2 short questions:
1. When we want parallel processing, we can either use a parallel hing in the query, or alter a table to be parrallel. My question is what is the difference in the following 2 syntax:
a. ALTER TABLE myTable PARALLEL (DEGREE 3);
b. ALTER TABLE myTable PARALLEL 3;
Does the "DEGREE" keywor make any difference? or they both are same statements?
2. When we enable parallel processing, how can we monitor oracle processes, to confirm that a certain table is being actually processed by multiple threads of a singe user process?
An early response would be highly appreciated. Thanks.

Please refer to the Oracle® Database Reference guide for details on these.
Had a look though my scripts and I have this one.. cannot recall if I "borrowed" it from somewhere and customised it and how old it is.. but it should (hopefully) still be mostly correct. It uses the virtual view v$px_process to determine the list of current PQ slaves in the pool and if they are used, map them to the Oracle session using them.

and     to_number (substr(x.server_name,3)) = l.id2(+)

and     l.sid = w2.sid(+)
and     x.sid = v.sid(+)
and     nvl(l.type,'PS') = 'PS'Use at own risk - best would be to verify that this is still valid using the Reference Guide. Or create similar ones using the available V$ views for the details you want to see (e.g. SQL statement executed per PQ, etc).

How to manage parallel processing for queue JMS/MDB?

Hello, we are developing a system in WebLogic Server 10g (10.3.0) that contains multiple JMS queues associated with each in an MDB. We need know how manage the parallelism of the message for each queue? for example:
Queue 1: up to 4 messages in parallel
Queue 2: up to 2 messages in parallel
Queue 3: up to 5 messages in parallel
Can also perform this configuration from the WebLogic Server Admin Console?
Thank you very much,
Lucas.

Thanks a lot Tom for the reply, I have read about the descriptor setting 'max-beans-in-free-pool' and I searched this concept at the Administration Console without success.
I suppose other way is create a “Session Pools” under the JMSServer, and then create a “Consumer” and define the setting “Messages Maximum”. One of the disadvantages is that “Session Pools” don’t support JTA, from the documentation:
+Session pools enable an application to process messages concurrently. Session pools are now used rarely, as they are not a required part of the J2EE specification, do not support JTA user transactions, and are largely superseded by message-driven beans (MDBs), which are a required part of the J2EE specification.+
I continue reading the MDB chapter of the performance and tuning guide in the documentation, thanks for any contribution to the topic.
Lucas.

How to enable Parallelism process in 10.1.0.5 database

Hi All,
We have oracle database 10.1.0.5 running in windows 2003 server.
I am trying to enable parallelism process in the database by including the following init parameters
PARALLEL_AUTOMATIC_TUNING
PARALLEL_SERVER
PARALLEL_MIN_SERVERS
PARALLEL_MAX_SERVERS
But while i am trying to bring the database i am getting an error message like these parameter has been deprecated.
Could anyone help me to enable parallel process in 10g database.
Thanks in advance.
Regards
Aruna

PARALLEL_AUTOMATIC_TUNING is deprecated since 10g. It's always true now. PARALLEL_SERVER is related to OPS (prior to RAC) and long time deprecated.
You enable parallel query with an ALTER TABLE statement like
SQL> ALTER TABLE SALES PARALLEL;or with a hint like
SQL> select /*+ parallel(sales) */ * from sales;Kind regards

How to implement parallel processing in oracle.

Hi Gurus,
In one our procedures we are calling 7 procedures internally. We want to execute them parallely insted of sequentially.
Please help me to resolve this issue.
thanks in advance...

Hi,
You have dbms_job package in Oracle 9i and dbms_scheduler from Oracle 10g.
Though you can run all these procedures parallel submitting via dbms_job, any exception/error out in any of these procedures need to be handled explicitly. Just be aware that once you submit these jobs, your application loses control of the execution and you have to build a whole infrastructure for rerun in case of an exception(log/exception tables, monitoring application to periodically check the exception tables, alerts from procedures in case of an exception and so on ...)
It's going to become more complex if you have any dependencies between these procedures.

Accessing internals: how to retrieve connection count info

Hi,
I'm wondering if it is somehow possible to get the actual state of the Toplink JPA pool, i.e. how many connections are in the pool, how many are active etc.
I was unfortunately not abel to figure out how to access this information, ie. the same thing which was possible with jdbc:
org.apache.commons.dbcp.BasicDataSource.getNumActive();
org.apache.commons.dbcp.BasicDataSource.getNumIdle();
Would be helpful to monitor the state of the pool and how many connections are currently opened to the db.
thanks
erich

Erich,
In JavaSE where the TopLink connection pool is most commonly used the following should work for you:
        Server server = ((EntityManagerImpl) getEntityManager()).getServerSession();
        int numWrite = server.getDefaultConnectionPool().getTotalNumberOfConnections();
        int numRead = server.getReadConnectionPool().getTotalNumberOfConnections();Doug

How to retrieve users info

does anyone Knows how to retrieve the users info.
for example if I want to create a LOV that contains the emails of all the users.
thanks in advance.

Retrieve them using and LDAP Search via DBMS_LDAP. Or you could cheat and search the ODS schema tables directly which contain all of the LDAP info. See the DS_ATTRSTORE table. Pull all attributes with a name like "mail"

Parallel process Before Remote client copy

i m going to perform remote client copy from production to sandbox how to enable parallel processing before that .
and its is hugh client and i want to do it fast can i start it in Foreground and if yes what parameter i have to set to what value to do it in foreground

Hi,
As far as i know there is no tcode where you can set parallel processing, you can just select remote cleit copy or local client copy this methods have parallel processing .

Parallel Processing Issue : call function starting new task

Hi
I am using the parallel processing functionality using the call function new task destination in group default Performing on end of task inside a loop ( i am splitting the internal table )
However when i am debugging the code, i am able to see the function module( it opens a new session in debugging ) , and i see that new task is started after the RFC Function module is executed .
How is this parallel processing ? I mean the new task starts after control returns back to main program , after the execution of the RFC FM.
I thought the idea was to have the same FM executing in multi threads. So that time is saved.

Thanks for the answers.
There were too many complications in the 'call function in new task ' option.
So we are trying it with the job submit option. So we are splitting up the data into smaller tables and submiting it with this statement : Submit 'prog' with selection-table 's_sel' via job 'job' and return .
Thanks
