CDCM WARNING subtask BEHIND--mm:ss TSN-n MNT-n

Reason:

This is a warning message that is issued by the Change Data Capture Monitor (CDCM) subtask to let you know a CDCL or CDCU task is behind the Log Area (LXX).

In the message text, subtask is either CDCL or CDCU, to let you know which subtask the CDCM has found to be behind the LXX.

In the message text, mm:ss indicates the amount of minutes mm and seconds ss by which CDCL is behind the LXX or CDCU is behind the first TSN record. If the value for minutes is larger than 999, the minutes and seconds are printed with plus (+) signs.

In the message text, the TSN indicates a count n of TSN (transaction sequence number) records. This count is the result of CNTTB or CNTKR commands and reflects the number of TSN records that currently exist.

In the message text, MNT indicates a count n of CDC maintenance LXX records. This count is the result of CNTTB or CNTKR commands and reflects the number of MNT records that currently exist.

Action:

If you already know the reason for the task being behind, address that issue.

If CDCL is behind and the reason is unknown, issue a STATUS_CDC console command on the MUF running the CDCL. STATUS_CDC makes available several messages that provide status. Based upon the status messages, do the following:

• If CDCL is open and running but cannot keep up, give the MUF a higher priority.
• If CDCL is closed because of an error, address the error and reopen the task.
• If CDCU is behind and not running, start it.
• If CDCU is running but cannot keep up, it needs a higher priority.
• If CDCU is running as fast as it can, but the volume of work prevents it from keeping current, the condition becomes expected and planned. In this case, the CDC base needs to be large enough to ensure it does not fill while waiting on the CDCU task.
