Hi All,
I'm currently upgrading our system to EHP6, and at the moment SUM is paused at 'Preparation for Downtime' page (I haven't continued it yet).
We're thinking of how to reduce the downtime duration. Based on previous system's upgrade logs, this MAIN_NEWBAS/TABIM_UPG has the longest runtime among all the downtime activities.
I need to seek your advise on how I can reduce the runtime for MAIN_NEWBAS/TABIM_UPG.
Based on some readings, from blogs, and other discussions, they say that 'mainimp_proc' parameter can be increased up to 4 or 6 to speedup the said step, and eventually the overall downtime duration.
It is mentioned that TABIMUPG.TPP can be found in <dir upg>\abap\bin, and from there I can change mainimp_proc value.
My question is does this file only being created once the MAIN_NEWBAS/TABIM_UPG starts? Because at the moment, I can't see it in the current system's upgrade directory <path to upgrade dir>/abap/bin. If yes, then from there, how should I change the value for mainimp_proc properly? So it will be adapted by the current processing step.
Appreciate your immediate response, as I cannot continue to the next step until I'm sure of what to do for MAIN_NEWBAS/TABIM_UPG,
Thanks a lot!
Regards,
Gie
