ZCOM Error Codes
Meanings of the Error Codes
Chapter 222
ZENOZLU (-3): ZLU table is full
Explanation: All of the defined program ZLUs have been assigned to
ZCOM user programs. This could be caused by user
programs that allocate an excessive number of ZLUs
without closing them after use. This could also be
caused by specifying a TTGEN Program-ZLU
parameter value that is too small.
Action: If the problem was caused by mismanagement of the
ZLUs by the application program, then correct the
application source code. Otherwise, increase the
number of ZLUs specified by the Program-ZLU
parameter in the TTGEN configuration file and
regenerate the ZCOM subsystem (using ttgen and
zmon).
ZEZTERM (-4): ZLU must be terminal type
Explanation: A non-terminal ZLU is specified in a ZCOM call which
expects a terminal ZLU (for example, zcntl).
Action: Correct the application source code.
ZEZPROG (-5): ZLU must be program type
Explanation: A non-program ZLU is specified in a ZCOM call which
expects a program ZLU (for example, zread).
Action: Correct the application source code.
ZENODE (-6): Unknown node number
Explanation: The node number specified in the call is not defined in
the TTGEN configuration file. This could be due to a
defect in the application source code or an error in the
TTGEN configuration file.
Action: Add or correct the Node-Definition parameters in the
TTGEN configuration file as needed. Otherwise,
correct the application source code.
