Requesting a SYSLOGR trace

Specify options for requesting a SYSLOGR component trace in a CTnLOGxx parmlib member or on the reply for a TRACE CT command.

Also, refer to the following as alternatives for specifying the CTnLOGxx parmlib member to be used:

IXGCNFxx SYS1.PARMLIB member (see IXGCNFXX SYS1.PARMLIB member).
SET IXGCNF=xx command.
SETLOGR CTRACE command.

Specify options for requesting a SYSLOGR component trace in a CTnLOGxx parmlib member or on the reply for a TRACE CT command.

You can change the options and the trace data space buffer size for SYSLOG trace while the trace is running. However, if the SYSLOGR trace has not been connected to an external writer and you are reducing the size of the trace data space buffer, 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 is discarded when the buffer size is reduced.

Note that if the trace is being turned off (either through a TRACE CT,OFF command or a CTnLOGxx parmlib member) and if the SYSLOGR trace is not connected to an external writer, the trace data must be dumped before turning the trace off to avoid loss of data.
