The FFDCNUMLOGS option specifies the number of log files that can be used for circular logging. The default value is 10.
Circular logging uses a ring of log files to provide recovery from transaction failures and system crashes. For example, when the dsmffcd.log file is full, it is renamed to dsmffdc.log.1. If a dsmffdc.log.1 file exists, the dsmffdc.log.1 file is renamed to dsmffdc.log.2. If a dsmffdc.log.2 exists, the dsmffdc.log.2 file is renamed to dsmffdc.log.3, and so on, until the FFDCNUMLOGS value is reached. If there is a log file that is renamed as the FFDCNUMLOGS value is reached, that log file is deleted.
The minimum value is 1. The maximum value is 100. The default value is 10.
Parameters

- Specifies the
number of log files that are used for circular logging.
If you specify a value of 1 and the log file size reaches the FFDCMAXLOGSIZE, the server continues to write to the log file. Any logging information is overwritten and the server continues to write to the log file.
