CCMS monitoring - Buffers - Program - SpaceUsed 100% - what to do?

[Former Member]

Hi SAP gurus,

This might be a lame question, but better ask a stupid question now, than live with the ignorance for the rest of the life.

In CCMS monitoring (TA rz20) in the node SAP CCMS Monitor Templates -> Buffers -> Program -> SpaceUsed - there's around 100% most of the time. When doubled-clicked I'll get to Tune Summary (also TA st02).

I've done some quick search (terms SpaceUsed or R3BufferProgramSpaceUsed), but didn't find a solution how to "fix" this.

To be honest, I don't even know what problems could this issue cause.

Could you please help me with this? Or provide some source?

Thanks in advance.

Cheers!

Shot Term Solution would be to re-cycle the SAP system so all buffers will be cleared.

Long term solution would be to change following paraneters

abap/buffersize

abap/pxa

P.S : You should make these changes in instance profile using RZ10. Do not make these chnages in default profile.

Thank you all for answers! Now I've got enough materials to study.

Thanks a lot.

Habu,

and per Juan's instructions, that would be in RZ10

That MTE monitors the usage of the program buffer, now the program buffer utilization in a system well configured should have enough space to avoid too many swaps... so if its close to 100% consistently and you can see multiple swaps in ST02 then you probably should increase the program buffer... that will be parameter abap/buffersize
