DSNR021I csect-name DB2 SUBSYSTEM MUST PERFORM GROUP RESTART FOR PEER MEMBERS

Explanation

This Db2 subsystem must perform the group restart phase to recover either the shared communications area (SCA) or the retained locks for nonstarting members in the data sharing group.

This message marks the beginning of group restart processing for peer members. Messages DSNR023I and DSNR024I or messages DSNR025I and DSNR026I are issued for each peer that is processed by this Db2 subsystem. Message DSNR022I marks the end of group restart processing for peer members.

This message is issued before this Db2 member enters the group restart process. The group restart process is synchronized among all group members that are starting and therefore participating in this group restart. After this Db2 member synchronizes with other members, it is possible that no peer processing will be necessary; in that case message DSNR022I immediately follows this message.

If it is necessary to recover both the SCA and retained locks, this message is issued twice; once for SCA recovery and again for the recovery of the retained locks.
