WCCILdata - REDU/WARNING - DataManager, handleRecoverySysMsgGot RECOVERY REQUEST, but we are waiting for Data BG start. Sending NACK

The following log message can be displayed during the startup in a redundant system when trying to start the recovery of the database. The log message is written to the PVSS_II.log-file.

WCCILdata (0), 2014.01.21 12:19:27.040, REDU, WARNING, 54, Unexpected state, DataManager, handleRecoverySysMsgGot RECOVERY REQUEST, but we are waiting for Data BG start. Sending NACK

The log message with symbolic names:

WCCILdata (0), <TIMESTAMP>, REDU, WARNING, 54, Unexpected state, DataManager, handleRecoverySysMsgGot RECOVERY REQUEST, but we are waiting for Data BG start. Sending NACK

This log message describes that the recovery (initiated by the other server project starting) is not possible since the startup of the local server project is not completely finished.

The databg manager is started with a short delay to reduce the system load during the initialization of other WinCC OA tasks and to decrease the startup time.

After the databg-manager has been started, the recovery is possible.

The following log messages are written on the other system:

WCCILdata (0), 2014.01.21 12:19:26.157, REDU, INFO, 0, , Sending recovery request to other replica
WCCILdata (0), 2014.01.21 12:19:26.162, REDU, INFO, 0, , Other replica temporarily unable to recover us, trying again later.

The first message describes that the starting server project is sending the recovery request to the other server.

The second log message describes that the recovery is not possible. Therefore, the server project will automatically try to recover again after one minute. User interaction is not required.
