4.0.6 upgrade question


Sterling Ferguson-II (1.6k9282269) | asked Mar 07 '14, 3:22 p.m.

Before you start the Quality Management application upgrade, run statistics to update the database tables. Otherwise, the migration might take several hours.

The following tables must contain up-to-date database statistics:

  • REPOSITORY.ITEM_STATES
  • REPOSITORY.ITEM_CURRENTS
  • REPOSITORY.ITEM_TYPES
  • LINKS.AUDITABLE_LINK

I chose derby as the database...does this apply?

Thanks John,

So this is a documentation issue? As your links look to be related to online migration, and I have not chosen that for my instructions:

There is more information on this topic in "http://pic.dhe.ibm.com/infocenter/clmhelp/v4r0m6/topic/com.ibm.jazz.install.doc/topics/r_repotools_onlineMigrate.html".
This is part of the overall QM online migration topic "http://pic.dhe.ibm.com/infocenter/clmhelp/v4r0m6/topic/com.ibm.rational.test.qm.doc/topics/c_online_mig_rqm.html".

The means for updating table statistics would be familiar to a DBA. For instance, RUNSTATS on a DB2 database.
This really only applies for repositories with a large volume of manual tests. A non-production Derby DB would not really benefit from the updated stats since this is targeted at existing enterprise deployments of QM.

Sterling,

as Derby is only meant to be used for testing and demo purposes, I would assume your DB is really small and it should not matter. I agree it is a bit confusing, because no DB vendor is specified. I could not easily find a database statistics command for derby.
