You can specify a single Db2
subsystem for use, when multiple Db2
subsystems exist for the selected SQL text.
About this task
If you attempt to view activity summary information for a dynamic SQL statement that runs
on more than one Db2 subsystem, you must specify the Db2 subsystem ID that you want to use with IBM®
Db2 SQL
Performance Analyzer for z/OS®.
Procedure
On the Db2 Query Monitor main menu, type 1 in the
Option field and press Enter.
Select the summary level you want to use to locate the dynamic SQL statement
that ran on multiple Db2 subsystems (these
include 1-Plan, 3-DBRM/Package, or 4-AuthID). If you select 2-DB2, you are not required to specify a Db2 subsystem using the Multiple Db2
Subsystems for SQL Text panel because you specified the DB2 subsystem of interest prior to
IBM
Db2 SQL
Performance Analyzer for z/OS analysis.
Type the S and A line commands to select and
request analysis for the dynamic SQL text of interest.
The Multiple Db2 Subsystems for SQL Text panel is displayed:Figure 1. Multiple DB2 Subsystems for SQL Text
