Server Class DEFINEs
If you omit this attribute, the default is OFF.
The LINKMON process or the ACS subsystem processes do not perform
checkpoint operations; it automatically retries I/O errors in the same way as the
operating system retries them. The TCP performs checkpoint operations, but does
not automatically retry I/O errors; this is done by the operating system.
This attribute is valid for Guardian and OSS server processes.
VOLUME volume-spec
For GUARDIAN processes, specifies the server class default volume and
subvolume names to be passed to the server process in the startup message.
This value is also used by the PATHMON process for the VOLUME attribute of
_DEFAULTS DEFINE.
For OSS processes, specifies the server class default Guardian volume and
subvolume used by the PATHMON process for the VOLUME attribute of the
_DEFAULTS DEFINE.
Defaults for file name expansion are based on values you specify for the CMDVOL
command and the SET PATHWAY NODEINDEPENDENT attribute. See the
command descriptions in CMDVOL Command and SET PATHWAY Command.
This attribute is valid for both Guardian and OSS server processes.
For more information on _DEFAULTS DEFINE, see Server Class DEFINEs.
Server Class DEFINEs
A server process context includes any DEFINEs that you specified using the DEFINE
attribute of the SET SERVER command and a _DEFAULTS DEFINE automatically
generated by the PATHMON process for values you did not specify. You can create
DEFINEs to specify the default volume and subvolume for a server process and to
specify files used by the server.
For example, these PATHCOM commands form part of a Guardian server class
definition:
SET SERVER PROGRAM $DATA.PW.SRVOBJ
SET SERVER DEFINE =_DEFAULTS, CLASS DEFAULTS, &
VOLUME $VOL.SVOL &
CATALOG $DATA.MYCAT
SET SERVER DEFINE =EMPLOYEE, CLASS MAP, FILE \SYS.$D.APPL.EMP
ADD SERVER EMP-SERVER
ON allows servers to lock and update audited files. The LINKMON, ACS
subsystem processes, or TCP process opens the servers with a
syncdepth of 0.
OFF does not allow servers to lock and update audited files. The LINKMON,
ACS subsystem processes, or TCP process opens the servers with a
syncdepth of 1.
