To identify threads with performance problems, you can filter your thread history by
thread IDs.
Before you begin
To complete this task, the thread history data collector must be running.
Procedure
-
From the KOBSEVTS panel, which appears
when you log in, select DB2. The active DB2 subsystems are
displayed.
-
Enter R next to the DB2 subsystem you want to use.
-
From the Thread ID tab, you can select threads by ID, using criteria
such as
Plan Name
, Auth ID
, Connect
, Con
Type
, Correlation ID
, CICS TX
, and IMS
PSB
. Note that Correlation ID
is case sensitive. You can use the EQ
("equal") or NE ("not equal") operators to specify that you want to see results that match, or
results that do not match, the string you enter. The question mark (?) wildcard can be used to
represent one character in a string. For example, you might specify TS12?4
to see
threads with Auth IDs such as TS1234
or TS1244
.
The asterisk (*) wildcard can be used to specify that you want to see any string. For example,
you might specify OMPE*
to see threads with Auth IDs such as
OMPEADMIN
or OMPETEST
. When you use the asterisk wildcard, any
characters you enter after the asterisk will be ignored. For example, OMPE*TEST
would be treated the same as OMPE*
. You cannot use the asterisk at the beginning of
a string, for example *ABC
. This would be treated as just a wildcard, with the
ABC
being ignored.
-
When you have specified the selection criteria you want to use, select
OK. The thread history summary is displayed.
