What is usage of the Sysview Performance Management Option for Db2 for z/OS (IDb2) EXCPDEF dataset?
When upgrade from Database Management r17 to r19 can the same dataset be used as is or requirement to reformat.
The EXCPDEF dataset is the exception dataset used for Exception processing. When upgrading from one release to another, you can either choose
not to copy the previous Exception definitions across when creating the Exception dataset through the Post Install panels or you can create a completely
new Exception dataset using the IDVSAMSY member in hlq.SOURCE.
NOTE: The member also has the definition for the PROFILE dataset, so that should be removed prior to running
Recommendation: Everything should be at the same maintenance level. Reason being, there may have been changes to dataset content being release specific. i.e. if you
generate r19 jobs into the r17 hlq.SOURCE library, it may overwrite existing JCL. You may reuse the hlq.PROFILE dataset, the hlq.EXCPDEF and hlq.SOURCE libs
but everything should be at the same maintenance level.
