-elfs error-log-file-size
Specify a value from 100 to 2,000,000 (in KB) for the size of the error log
files (dlmmgrn.log (n indicates a file number from 1 to 16)). The specified
files size is applied to HDLM manager logs.
By specifying both the error log file size and the number of error log files,
you can collect up to 32,000,000 KB (approximately 30 GB) of error logs
in total.
When the size of all the log files in a log file group reaches their maximum
value, the new log data will overwrite the existing log data, starting with
the oldest log data.
-elfn number-of-error-log-files
Specify the number of error log files (dlmmgrn.log (n indicates a file
number from 1 to 16)). Specify a value from 2 to 16.
By specifying both the error log file size and the number of error log files,
you can collect up to 32,000,000 KB (approximately 30 GB) of error logs
in total.
-systflv trace-level
Specify the trace output level.
Log files for which the trace level can be set are hdlmtrn.log (where n is
a value from 1 to 64).
Table 6-4 Trace Level Values on page 6-17 shows the values of the trace
level. When an error occurs, we recommend that you set the value of the
trace level to 1 or higher and re-collect log information.
Table 6-4 Trace Level Values
Value Description
0 Does not output any trace.
1 Only outputs error information.
2 Outputs a summary of program operation.
3 Outputs details of program operation.
4 Outputs all information.
The higher the error log collection level value, the more log information
will be output. As the amount of log information that is output increases,
the amount of time before existing information will be overwritten
becomes shorter.
-systfs trace-file-size
Specify a value from 100 to 16,000 for the size of the trace log file (in
KB).
By specifying both the trace file size and the number of trace files, you
can collect up to 1,024,000 KB of trace files in total.
If you specify a value smaller than the set value, the KAPL01097-W
message is displayed to confirm execution, and the trace file is
temporarily deleted.
