Performing a cold start

In some cases, for example when advised to do so by IBM® Support, you might need to perform a cold start in a data sharing environment. A cold start occurs when STARTRBA and ENDRBA are equal on the CRESTART statement of the DSNJU003 (change log inventory) utility.

Procedure

To cold start a Db2 subsystem in a data sharing environment:

  1. Stop all other members of the data sharing group.
  2. Cold start the chosen member using ACCESS(MAINT). The cold start deallocates the group buffer pools to which this member was connected.
  3. Resolve all data inconsistency problems resulting from the cold start.
  4. Start all the other members and restart this one without ACCESS(MAINT).
