Configuration Database Files Used for the OSS
Sockets Local Server
The ZOSSSERV file is the OSS sockets local server configuration database, and it
contains an automatically created entry that identifies the characteristics of the OSS
sockets local server process.
This file must be edited by the system manager using the SCF ALTER SERVER
command. ZOSSSERV need not be configured before the root fileset is first mounted
or before the first OSS sockets local server is started. The default configuration for
ZOSSSERV that is created by OSSMON is complete.
Entries in the ZOSSSERV file must follow these rules:
•
There must always be a #ZPLS entry for the OSS sockets local server process,
$ZPLS.
•
Primary and backup processor numbers must be assigned such that no single
processor failure affects more than one server process pair.
HP recommends that you specify processors in the ZOSSSERV file that are not used
by either the OSS Monitor or the FSCK utility (as specified by the ZOSSPARM file
FSCKCPU value).
Changes to the ZOSSSERV file take effect only when the corresponding server is
stopped and restarted.
When a default ZOSSSERV file is created by the OSS Monitor, it contains an entry for
the default OSS sockets local server process, $ZPLS.
Beginning with RVU G06.10, when HP shipped a system with the OSS environment
preconfigured, the #ZPLS entry matched the default, as follows:
Beginning with RVU G06.15, when HP shipped a system with the OSS environment
preconfigured or you used the OSSSETUP utility to configure your system and
accepted all defaults, ZOSSSERV contained the following initial OSS sockets local
server information:
