ZSENDTIMEOUT
specifies the timeout value that a link manager (such as a LINKMON process or
Pathway/iTS TCP) uses for the I/O operation to the server process.
You must specify ZSENDTIMEOUT as a quadrupleword (64-bit) microsecond
value; the value must be in the range of 0 through 18 hours or 0 through 1092
minutes, or 0 through 16,383 seconds. To convert a value expressed in hours,
minutes, or seconds into a quad-word microsecond value, use the algorithm:
hours * 60 = minutes
minutes * 60 = seconds
seconds * 1,000,000 = microseconds
If you do not assign a value to this field, there is no timeout on the server I/O
operation; that is, the link manager waits indefinitely for the server I/O operation to
complete.
A SERVERCLASS_SEND_ call that times out returns Pathsend error
FESCSERVERLINKCONNECT (904) and file-system error 40. A SCREEN
COBOL 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 has
completed. The initial open of a server process by a LINKMON process 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:
The LINKMON process does not perform checkpoint operations; it automatically
retries I/O errors in the same way as the operating system retries them.
If you are using Pathway/iTS, the TCP performs checkpoint operations before and
after each SEND request, but does not automatically retry I/O errors; 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, the default is ZPWY-VAL-OFF.
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.
