2.104 query_bck_cs_trace
The query_bck_cs_trace command returns information about the current options for back-level client-server
tracing. Client-server tracing is the tracing of data sent between a current-level SNAplus2 server and a back-level
server or client. This command is used only when you are in the process of migrating a client-server SNAplus2
system to a new release of the software, so that one or more servers are running the current-level software and
providing support for computers running the back-level software. For more information about the migration process
and about support for back-level computers, refer to the
HP-UX SNAplus2 Migration Guide.
This command must be issued to a running node on a computer where the back-level support software is running.
