How many processes could be engaged by one background job?

How many processes could be engaged by one background job?

If we have specified the RFC group and defined the group in program as well.

But how to know exactly number of processes for this job?

Hello Chen,

If you are using RFC groups definition of parameters are done on RZ12 transaction.

Go to RZ12 and  create a group to assign your system. When you double click the assignment you will see the determination of the resources.

Profile parameters for the issue are below.

Table Names of Profile Parameters RZ12	Profile Pparameters
Activated (0 or 1)	rdisp/rfc_use_quotas
Max. Requests in Queue (%)	rdisp/rfc_max_queue
Max. No. of Logons (%)	rdisp/rfc_max_login
Maximum No. of Separate Logons (%)	rdisp/rfc_max_own_login
Max. Number of WPs Used (%)	rdisp/rfc_max_own_used_wp
Minimum Number of Free WPs	rdisp/rfc_min_wait_dia_wp
Max. No. of Comm. Entries (%)	rdisp/rfc_max_comm_entries
Max. wait time	rdisp/rfc_max_wait_time

Thank you for your reply.

But i knew that we can see the setting but i am writting to get exact number  of specified background job

Hello Chen,

AFAIK It changes according to your program criterias.

You can define it whenever you are calling the program.

You define how many parallel jobs will your program start etc.

The parameters mentioned above restricts the usages.

Do you mean the fixed paralle number is defined in the program?

[yakcinar]

Hello Chen,

Yes. AFAIK parallel processing is defined in programs or in criterias of the programs.

Whenever you run the program it occupies that amount of WPs and those WPs run the job in parallel.

I saw the group define but i dont see the fixed number  in program that is why i am still confused.

Besides i the above thread also mentioned if the paralle process define as below ,it could be dynamic.

Hello Chen,

How many times does your program perform that "call function ... in group..."?

For instance, is this call performed inside a loop? How many times will your program loop?

This is the number of parallel tasks that your program will open, and these cannot exceed the resources available (parameters already mentioned in this thread) when your program is running.
