Hi,

I know it. ASE 15.7 isn't better way for BW... I hope tu upgrade it next year. Now I'm living with poor performance. Really poor performance. We have also an ERP box with the same HW configuration that runs so fat and it is used by more then concurrent users.

Have you got any suggest on ASE tuning side? It's a Windows box with 128 GB ram

Dear Ganimede,
I'm afraid that the output is unreadable. For a next time please attach it as a file.
Anyway, an output of configuration file only can be useful to understand your sizing configuration but it won't the unique information required for a BW tuning.

Check the guide from SAP Note 1680803 - SYB: SAP Adaptive Server Enterprise - Best Practice for SAP Business Suite and SAP BW , ie Chapter 6.2.5 regarding configuration of the default data cache, your current size is 82920Mb, the suggestion is to have 80% of that size configured to the 128K I/O pool and the remaining to the 16K I/O pool. Start with that. Chapter 6.2 ASE Sizing.

You might need to identify the most consuming queries, if any (that can be seen thru DBACockpit). Ensure that your infocubes are being compressed. Ensure statistics are up-to-date. Recommended to read Chapter 7.6 of that Best Practices Guide.

Consider to upgrade this year ;)

HTH,
Victoria.
