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

The component trace can be started before the job to be traced is started or while the job is running. The trace is active for the first instance of the job. For example, if the same job name is used for multiple jobs, only the first job with that name is traced. Subsequent jobs with the same name are not traced unless the component trace is stopped and then restarted. A trace external writer is required if the trace records are to be written to a data set. A sample started procedure is shipped as GSK.SGSKSAMP(GSKWTR). Copy this procedure to SYS1.PROCLIB(GSKWTR) and modify as necessary to meet your installation requirements. This MVS™ operator command starts the trace external writer:
A single SSL component trace may be active at a time and the trace can include from 1 to 16 separate jobs. The trace buffer size must be between 64K and 512K and defaults to 64K. System SSL supports these options for CTRACE:
For example, to start an SSL component trace for jobs CS390IP and DB1G which includes all non-dump trace entries and writes the trace records using the GSKWTR trace writer:
To start an SSL component trace for job CICS1 which includes all trace entries and writes the trace records using the GSKWTR trace writer:
These commands stop the SSL component trace and close the trace writer data set:
System SSL does not require a default trace member in SYS1.PARMLIB since SSL component trace is not activated until the operator enters the TRACE command. SYS1.PARMLIB members can be created for frequently used trace commands and the member name can then be specified on the TRACE command to avoid the operator prompt for trace options. Starting and stopping the in-storage trace is done the same way as the external writer trace except the external writer name on the trace command should not be specified. These commands start the SSL component trace using the in-storage trace table:
This command stops the SSL component trace using the in-storage trace table:
