The following tables indicate the parameters you can specify on TRACE CT commands and a REPLY.
| Parameters | Allowed on TRACE CT for trace? |
|---|---|
| ON, nnnnM, or OFF | Yes |
| COMP | Required |
| SUB | No |
| PARM | Yes |
| OPTIONS | Yes, allowed only on REPLY |
If you reduce the size of the trace data space buffer and the SYSLOG trace has not been connected to an external writer, you must dump the contents of the buffer (see Obtaining a dump of system logger information) before reducing the buffer size if this data is important for debugging. Trace data in the trace data space buffer is discarded when the buffer size is reduced.
If the trace is being turned off (either through a TRACE CT,OFF command or a CTnLOGxx parmlib member) and the trace is not connected to an external writer, the trace data must be dumped before turning the trace off to avoid loss of data.
| Parameters | Allowed on REPLY for trace? |
|---|---|
| ASID | Yes |
| JOBNAME | No |
| OPTIONS | Yes |
| WTR | Yes |
