NOF API Verbs
QUERY_BCK_CS_TRACE
3.93 QUERY_BCK_CS_TRACE
This verb returns information about the current options for back-level client-server tracing (tracing of data sent
between a current-level SNAplus2 server and a back-level server or client). It is used only when you are in the
processs 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 on support for back-level computers, see the
HP-UX SNAplus2
Migration Guide.
This verb must be issued to a running node on a computer where the back-level support software is running (for
more information, see the HP-UX SNAplus2 Migration Guide).
