ECC system performance is very poor

[Former Member]

Hi Experts,

we are facing major performance issues for the past 15 days. please let me know if any forums, SAP notes or any other information which will help me to resolve this performance issue. the configuration is as follows:

Server: ECC 6.0 (one CI and 2 app. servers). we have not configured background jobs on the 2 application servers as we are unable to access one mounted directory from the both. I will explain it clearly if this might be a show stopper.

OS: AIX 5.3.7.3 (no. of CPUs =12), RAM 17 GB

Database: Db2 v9.5(fix pack 0) (total DB size= 600 GB)

max number of concurrent users=1000.

please let me know what all the parameters I need to consider. i wanted to tune all SAP, AIX and DB related parameters.

Thanks in advance,

Mohan K

Mohan,

Performance is low all the time or during peak hours.

Check your CPU, Memory & Swap use in system. Update statastics regularly. check health of database index. Check read write time to database.

Please go through following thread. Lot of useful information.
