Capturing trace data through environment variables z/OS Cryptographic Services System SSL Programming SC14-7495-00 |

In order to capture trace information using environment variables, the trace environment variables GSK_TRACE and GSK_TRACE_FILE must be exported before the start of the SSL application.
Note: Care needs to be taken if the application being traced
is multi-processed. If multiple processes write to the same trace
file, file corruption might occur. To allow trace information to be
obtained, the trace file name specified should contain a '%' character
in the file name. This allows the process identifier to be placed
within the file name and each process to write to its own trace file.
It is suggested that if the default trace file value is not being used, the trace file name always contain a '%' character. This eliminates the need to know whether the application being traced is multi-processed or not. Once the trace file is produced, it must be formatted. To format the file, use the System SSL gsktrace command as follows:
