SAP DB2 performance issues

$

Hello everyone,

 

I'm new in db2 for LUW and I have the following questions:

 

How can I check the total memory DB2 is using? I have STMM configured. I have two parameters DATABASE_MEMORY (automatic) and INSTANCE_MEMORY? Do I need to sum them?

 

I have many secuencial reads in SM50, any advices about how to proceed? (for standard/non standard reports/tables). In ST03N I have High Database time (almost 60% of the response time) any advices about how to proceed?

 

Any useful link will be appreciated.

 

Regards,

 

JAM

 

System information: NW 7.0 EHP1 / DB2 9.7 FP4 / AIX 6.1
