You can control Client daemon tracing using the cicscli command. You can improve performance while tracing by using memory mapped tracing.
cicscli -d[=size]
Where size is
an optional parameter which specifies the maximum size of data, in
bytes, to be traced with any individual trace message. The default
is 512 bytes. cicscli -d -s
To trace the Client daemon from startup on Windows, set the trace options as startup parameters. For more information, see Setting CICS Transaction Gateway startup override options
The Client daemon writes trace entries to a file, the default file name is cicscli.bin. On UNIX and Linux systems the trace file is created in the /var/cicscli directory. On Windows systems the trace file is created the <product_data_path> directory.
Performance while tracing is on can be improved by using memory mapped tracing. With memory mapped tracing, data is stored initially in memory, and flushed to disk by the operating system's paging mechanism. For more information, see Memory mapped tracing. For important security information, see Security considerations for UNIX and Linux systems.
cicscli -d -b
or
cicscli -d -m=component_list -b
Use the cicsftrc utility to format the trace file; see Formatting the binary trace file.
