2: ZTCI-EVT-IOP-READ-ERR
ZCOM-TKN-SUBJ-SUBNET
contains the name of the TCP/IP subnet that is the subject of this event message.
ZEMS-TKN-EMPHASIS
is a header token that contains the value ZSPI-VAL-TRUE, indicating that this is a
critical event.
(ZEMS-TKN-) CONSOLE-PRINT, CPU, CRTPID, GENTIME, LOGTIME, PIN,
SYSTEM, and USERID
are automatically placed in the header when the EMSINIT procedure is called and
the event message buffer is initialized. For a description of these tokens, see
Section 5, Common Definitions. For details on any of the EMS tokens, see the
EMS Manual.
ZTCI-TKN-SEV
contains the value ZTCI-VAL-SEV-WARN. This value indicates that
ZTCI-EVT-IOP-READ-ERR is only a warning message. The process continues to
function, but some functionality has been lost; for example, the network may be
going down, or a device accessed by the TCP/IP subsystem may be experiencing
errors.
ZTCI-TKN-ERR-NUM
contains the number of the file-system error that has occurred. For more details,
see the Guardian Procedure Errors and Messages Manual.
ZTCI-TKN-IOPNAME
contains the name of the X25AM line and subdevice being accessed by the
TCP/IP process for transmitting and receiving data when the READ operation
failed.
Event-Message Text
In the text message, error corresponds to the value in ZTCI-TKN-ERR-NUM and
iopname corresponds to the value in ZTCI-TKN-IOPNAME.
Cause. A READ operation to the I/O process has failed.
Recovery. The TCP/IP process automatically attempts to reopen the I/O process
when it is closed as a result of an error. If successful, operator intervention is not
required. However, if the attempt to reopen fails, the operator must check the X25AM
line (for X.25 subnets) to verify that the problem is not at the subdevice or line level.
The TCP/IP process continues to try to open the port or subdevice at one-minute
intervals.
