Hi experts,
since a few days we have a big performance impact by sql-statements on tabel RESB.
e.g. we have select-statements, which did take around 10 minutes and now over 3 hours.
We have already checked indizes and table consistent. Also table checks in DB02.
If I make the same sql on our testing system it is still fast, so only in the productive sytem we are facing this problem.
The table size in both systems is similar.
At the moment selecting around 1000 rows in PROD systems takes more than 10 minutes.
In Q System it takes just a few minutes for more than 100 000.
Can someone help to analyze the problem?
Thank you
