Configuration Database Files Used for the OSS
Transport Agent Servers
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 4-5 on page 4-22 shows how the OSS sockets local server entries in the
ZOSSSERV file correspond to processes, disk files, and disk volumes. The entries
control the processor in which each member of the process pair normally runs.
Configuration Database Files Used for the OSS Transport Agent
Servers
The ZOSSSERV file is the OSS transport agent server configuration database, and it
contains an automatically created entry that identifies the characteristics of each OSS
transport agent server process. This entry cannot be changed.
When a default ZOSSSERV file is created by the OSS Monitor, it contains a #ZTAnn
entry for each copy of the OSS transport agent server process, $ZTAnn. These entries
have the following default values:
The number of entries and the value of nn for each entry depends on the number of
processors on the node that are up when the OSS Monitor starts.
