Description:

When attempting to run an extract and action procedure in CA Database Analyzer for DB2 for z/OS (PDA), the Action procedure has Action conditions selected that are processed against the RTS tables.

In the case reported there were problems with zero values in columns of the RTS tables. E.g. TOTALROWS/TOTALENTRIES columns of TABLESPACESTATS/INDEXSPACESTATS. These columns were used in the Action Conditions that were chosen and caused problems because we do not expect them to be zeros.

Solution:

There are "known" problems with RTS.

At the time of writing (March 2010) the following are IBM APARS concerning this.

We recommend that you follow the advice from IBM concerning the above APARS.

Note: Applying the PTF may not fix existing RTS rows and further action may be required.

For r12 PDA, you have a new feature that will allow you to update RTS entries, with values taken from the DB2 Catalog, where missing values occur. This can be found under the Statistics Maintenance option, then update Statistics for IBM Real-Time Statistics (RTS).
