APAR status

  • Closed as program error.

Error description

  • Catalog navigation commands that show a list of packages related
to the object (like the K line command on the table), can cause
performance issues on systems with a large number of packages.
This is due to an unoptimized SELECT query.

Problem summary


    

  • ****************************************************************
* USERS AFFECTED: Users of Db2 Administration Tool for z/OS    *
****************************************************************
* PROBLEM DESCRIPTION: Performance and consistency issues      *
*                      occur when using catalog navigation     *
*                      for packages.                           *
****************************************************************
An unoptimized SQL query is used in catalog navigation to get
the list of packages that depend on the selected object. This
query results in a longer response time for some line commands
that display the ADB21K (Packages) catalog navigation panel.

Also, using line commands to navigate between the ADB21K panel
and other object panels multiple times might result in
inconsistent results for packages.
