Configuration Files Used for the OSS Name Servers
If your system has been upgraded from a G-series RVU preceding G05.00, the OSS
Monitor automatically creates an initial ZOSSSERV file containing the information from
the older system’s ZPCONFIG and ZPMNTTAB files.
If your system is upgraded to a G06.17 or later G-series RVU, the OSS Monitor
automatically upgrades an existing ZOSSSERV file and creates a backup copy of your
original file in $SYSTEM.ZXOSSMON.ZOLDSERV.
Figure 4-4 shows how the OSS name server entries in the ZOSSSERV file correspond
to processes, disk files, and disk volumes. The entries control OSS name server
caching, request timeout between an OSS name server and an SQLCAT, and the
processor in which each member of the process pair normally runs.
