TS/MP 2.5 Management Programming Manual

SEND operation that times out has a server I/O error 12 reported in the SCREEN
COBOL TERMINATION-STATUS special register.
The ZSENDTIMEOUT attribute is not active until the first OPEN procedure is
complete. The initial open of a server process by an ACS subsystem processes has
an automatic 5-minute timeout period; the initial open of a server process by a TCP
has an automatic 10-minute timeout period.
ZTMF
specifies whether servers in this server class can lock and update data files audited
by the TMF subsystem. The valid values are:
ZPWY-VAL-OFF Does not allow servers to lock and update audited files. The
link manager opens the server processes with a syncdepth of
1.
ZPWY-VAL-ON Allows servers to lock and update audited files. The link
manager opens the server processes with a syncdepth of 0.
The ACS subsystem processes do not perform checkpoint operations; they
automatically retry I/O errors in the same way as the operating system retries them.
If you are using Pathway/iTS, then the TCP performs checkpoint operations before
and after each SEND request, but does not automatically retry I/O errors, then I/O
errors are retried by the operating system. For more information about TCPs, see
the Pathway/iTS System Management Manual and the Pathway/iTS Management
Programming Manual.
If you do not assign a value to this field, then the default is ZPWY-VAL-OFF.
ZDEFAULTVOLUME
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 _DEFAULTS
DEFINE.
The node name can be either a specific node name or \*, a generic name
representing the node on which the PATHMON process is currently running. If you
do not specify a node name, the default node for the file-name expansion is
determined by the value you specify for the ZNODEINDEPENDENT field of the
START PATHWAY command.
This is a required field for Guardian and OSS server processes.
ZOWNER
is the user ID that controls access to a server class from a Pathsend requester.
(Pathway/iTS TCPs do not use this attribute.) The user ID must be known to the
system in which the server class is running. The value of the ZOWNER field works
in conjunction with the value you set for the ZSECURITY field.
For more information on this field, see “ZPWY-DDL-OWNER-ID” (page 65).
If you do not assign a value to this field, then the default is the owner ID of the user
who starts the PATHMON process.
ZSECURITY
specifies the users, together with the ZOWNER field, who can access a server class
from a Pathsend requester. (Pathway/iTS TCPs do not use this parameter.) For more
information on this field, see “ZPWY-DDL-SECURITY-VALUE” (page 69).
