Solved: SAP very slow when online backup program is runnin...

Former Member · ‎11-20-2009

Hi Folks,

I have a script that is scheduled to run everyday.Prior to upgrade the SAVLIB command for online backup job for R/3 4.6c database was -

SAVLIB LIB(<database_library>) DEV(TAP02) ENDOPT(*LEAVE) +

CLEAR(ALL) SAVACT(SYNCLIB) +

SAVACTWAIT(21600 21600 21600) +

SAVACTMSGQ(QSYSOPR) OUTPUT(*PRINT)

After SAP upgrade from 4.6c to ERP2005 SR3, changed the command as per SAP Note 825473 as-

SAVLIB LIB(R3SBDDATA R3SBDJRN R3SBTDATA R3SBTJRN) +

DEV(TAP02) ENDOPT(LEAVE) CLEAR(ALL) +

SAVACT(*SYNCLIB) SAVACTWAIT(3600 +

*NOCMTBDY *LOCKWAIT) SAVACTMSGQ(QSYSOPR) +

OUTPUT(*PRINT)

The system is slow when backup is in progress and irresponsive most of the times.

Any idea why this is happening?

Hi Sai,

first of all:

Why did you change anthing when you were happy before ?

The upgrade doesn't need this change. You only do it VERY RISKY in case of emergency approach as you NEED to run APYJRNCHGX now.

=> Why don't you go back to your "good" backup ?

Next point:

I would strongly recommend to use *LIB instead of *SYNCLIB in order to not sync too many objects at the same time (in both approaches) ...

Hi Folks,

Thanks Volker.

After upgrade, when Online backup used to run, no one was able to log in to SAP as all the work process were in Hold state.

However, after the change in backup command the system is slow however logon is possible and not much of the process are in Hold state.

As suggested I will try changing *SYNCLIB to *LIB. Anyone has any other suggestions?

Regards,

Sai
