Optimizing Performance 

Deleting Processed LUWs with a Background Job

In tRFC and qRFC, an entry is made in database table ARFCRSTATE for each LUW that is to be processed. The default setting for function module ARFC_DEST_CONFIRM means that this entry is deleted two minutes after the successful completion of the LUW in question.

To improve performance, you can schedule processed LUWs to be deleted using a background job and thereby separate it from the actual qRFC processing.

Proceed as follows:

       1.      Set profile parameter abap/arfcrstate_col_delete in profile DEFAULT.PFL (transaction RZ10) to the value 'X' for all application servers.

Function module ARFC_DEST_CONFIRM can no longer delete the entries in ARFCRSTATE directly.

       2.      Use report RSTRFCEU to schedule a batch job. The delete task is then executed regularly (minimum: 2 minutes, default: 5 minutes) in the background.

Do not make the time between delete jobs too large because the ARFCRSTATEtable can grow very quickly.
