DSNB745I csect-name THE TRANSITION BACK TO SIMPLEX MODE HAS COMPLETED FOR GROUP BUFFER POOL gbpname
Explanation
The named group buffer pool has completed the transition from duplex mode back to simplex mode.
This message is preceded either by message DSNB743I or by message DSNB744I which indicates the reason why duplexing was stopped. This message is issued by each Db2 member connected to the group buffer pool.
System action
The group buffer pool is now back in simplex mode which means that writes of changed pages to the group buffer pool are now simplexed. If DUPLEX(ENABLED) is specified in the active CFRM policy for the group buffer pool, then duplexing will be automatically reinitiated, if duplexing is still possible. This would mean that the group buffer pool is only temporarily back into simplex mode (it is soon to be entered back into duplex mode).
