Optimizing database query performance
The RUNSTATS command updates the database query access plan for each table
and index. To optimize database query performance, run RUNSTATS at least once
a week when IBM WebSphere Partner Gateway application and database activity is
at a minimum. As database traffic increases, run RUNSTATS more frequently, up to
once a day.
Notes:
1. Since RUNSTATS updates database system information, lock time-outs
2. A lock timeout may occur when RUNSTATS and db2rbind are run
Another method of updating the DB2 access plan is to use the reorgchk command.
From a DB2 command window, run the following commands:
1. db2 connect to <database name>
2. db2 -v reorgchk update statistics on table all
3. db2 connect reset
Note: Ensure that you stop all Websphere Partner Gateway components before
starting this procedure. You should also stop and restart the database instance after
you finish the reorgchk.
Resolving event 210031
About this task
