Description
The TRACE_FILE_LINES option specifies the maximum number of lines to write to the trace file.
When the maximum number of lines has been reached, the trace file will wrap around and start writing trace entries after the trace header lines.
Tracing is activated, and a trace file is generated, when the MESSAGE_LEVEL option is set to TRACE.
Usage

Configuration File Keyword | trace_file_lines number | | | | |
Values
IBM i | The current record length is 384 characters. As allocated on the AS/400 (i5), the maximum number of records is 509,000. Increasing TRACE_FILE_LINES beyond this value requires manual adjustment of the file size via the CHGPF command. Default is 200,000. If space is limited in the ASP where the trace file is located, set this to a smaller value. To avoid trace file wrapping, set this to a larger value. Please read the trace_file_lines information in the UNVCONF(UDMS) file member before increasing this value. |

UNIX | The average size of a trace file line is 50 characters. Default is a very large value of 200,000. If space is limited in the trace file directory (specified with the TRACE_DIRECTORY option), set this to a smaller value. |
---|
z/OS | The average size of a trace file line is 50 characters. The trace file wrapping is only supported with sequential data sets that have a fixed record format. Partitioned data sets or variable record formats are not supported. Default is 200,000. |
