DSNJ016E csect-name WARNING - SYSTEM CHECKPOINT PROCESSOR MAY HAVE STALLED. LAST CHECKPOINT WAS TAKEN date-time.

Explanation

While switching active log data sets, Db2 found that there has not been a system checkpoint taken since the last time Db2 switched active log data sets. date-time is the date and time of the last system checkpoint. There should be at least one system checkpoint on each log data set.

System action

Db2 continues processing. If statistics class 3 is active, IFCID 0335 is written.

This message is non-scrollable. It remains highlighted on the console until you take the appropriate action.

This message is deleted when a system checkpoint is taken.

System programmer response

This message might be an indication that the system checkpoint processor may no longer be functioning. This situation can result in a very long restart if logging continues without a system checkpoint. You should monitor system checkpoint activity very closely. You can use the -DISPLAY LOG command or run the Print Log Map utility (DSNJU004) to display the most recent checkpoint. If Db2 continues logging beyond the defined checkpoint frequency, you should quiesce activity and terminate Db2 to minimize the restart time.

Prior to terminating Db2, obtain a dump of the Db2 address spaces for problem determination.
