SAP Parameter rdisp/rfc_min_wait_dia_wp config

Hi All,

In our production system , we have installed DB+CI on one single host and all the application server's on another host.

Scenario:-

Whenever jobs are getting triggered from Application server , all the jobs are internally running  on CI , and CI becomes unavailable.

Can anyone tell me how to avoid this situation , also i come to know about rdisp/rfc_min_wait_dia_wp parameter.

Please let me know what are all the other steps i need to perform in production to do tunning.

Really appreciate your inputs.

Thanks & Regards

Pradeep.

Hello Pradeep,

You can read the parameter's documentation through the transaction RZ11.

In addition, the SAP note 74141 has other parameter related to RFC resources.

What seems to be occurring is that your job is not using a logon group to distribute the load of the parallel tasks it creates.

You can create a load balance group for that at the transaction RZ12. Then you should reach out to your functional team so they adjust their job to use that group.

Hi Isaías,

The same issue happening when  we execute the program in dialog mode.

We run it in App server but it takes dialog work process from CI. Is there any reason why this happens.

Please suggest.

Thanks & Regards,

Pradeep.

Hello Pradeep,

Starting parallel tasks in a job or in dialog mode is exactly the same.

The report starting the parallel tasks must provide a parameter to inform which (RZ12) logon group is to be used to start the tasks.
