Number of available logs less than critical threshold.
KDP_LOGN_Critical monitors the availability of primary active logs. Active log data sets are allocated to DB2 during start-up processing. When an active log data set is full, it is automatically archived by DB2 to an archive log. When an active log is successfully archived, it is available for reuse.
The availability of active logs is critical to the functioning of DB2. If no active log is available, the DB2 subsystem hangs until one becomes available.
The lack of an active log could be caused by an insufficient number of logs defined at installation time, too small a log data set size, or possibly because of problems encountered during the archive process. A critical condition is detected when the logs available is less than one. The situation's formula is:
