Normal shutdown

After a normal shutdown of Db2, the coupling facility structures specify different states for the connections and structures.

The following table summarizes the information that you see after a normal termination.
Table 1. States of structures and connections after normal Db2 termination
Structure Connections State
SCA None Allocated
Lock Failed-persistent 1 Allocated
Group buffer pools None with CASTOUT(YES); Failed-persistent with CASTOUT(NO) 2 Unallocated with CASTOUT(YES); Allocated with CASTOUT(NO)
Notes:
  1. If a member has no retained locks, its failed-persistent connection to the lock structure is removed when it shuts down. If this is the last member to shut down, the connection remains in a failed-persistent state.
  2. If castout failure occurs during shutdown, group buffer pool connections show as failed-persistent, even though Db2 terminates normally.
