IFCID 366/376: include SQL text in the trace records

The analysis of IFCID 366/376 is done via SMF records. When these records are available (one day delay), it is nearly impossible to match the statement ID to a statement in dynamic statement cache, because the statement might be already discarded....

Display Trace owner when OPx buffer used

The -DISPLAY TRACE(*) command does not indicate which address space owns the trace when the destination is OPx. Since the OPx destination must be managed by some product/address space it would be helpful to know this. A typical scenario: The syspr...

Restart Time of DB2 should not be dependent on SCA size

During restart of DB2, the time difference between DSNR003I and DSNR004I is a function of the SCA size. Case TS009645595 was opened and has all the details. But in summary: this large time differenece of 30 seconds (in our case) is a function of t...
