ZPWY-MAP-DEF-TCP
The value for this field can be:
After an abnormal failure, the action caused by this option is equivalent to using a
START TCP command followed by a START TERM command for all TERM objects
configured and running with ZAUTORESTART and set to a value from 1 to 32,767
at the time the TCP stops.
If you do not assign a value to this field, the default is 0.
ZCHECKDIRECTORY
specifies whether the TCP checks the SCREEN COBOL directory file (for example,
POBJDIR) for the latest version of a called program when executing a SCREEN
COBOL CALL statement. ZCHECKDIRECTORY can have the following values:
If you do not assign a value to this field, the default is ZPWY-VAL-ON.
For more information about this option, see REFRESHCODE TCP on page 7-13.
ZCODEAREALEN
is the number of bytes that the TCP allocates in its extended data segment for
SCREEN COBOL object code. Valid values range from 0 through 2,147,483,647.
0 Specifies no automatic restarts.
1 through 32,767 Directs the PATHMON process to allow this many
automatic restarts in 10 minutes.
-1 Directs the PATHMON process to allow unlimited
automatic restarts.
ZPWY-VAL-OFF Directs the TCP to check the directory file for the latest
accessible version of the called program if the called program
unit is not in memory. If the called program unit is in memory,
the TCP uses that version. This option does not ensure that
the TCP uses the latest accessible version of the called
program unit.
Note. Configuring the ZCHECKDIRECTORY field with ZPWY-VAL-OFF does not prevent
the TCP from searching the TCLPROG file defined for a TERM or a PROGTERM object
on every SCREEN COBOL CALL statement.
ZPWY-VAL-ON Directs the TCP to check the SCREEN COBOL program
directory file for the latest accessible version of the called
program unit for each call. This method ensures that the latest
version is used.
Note. The maximum value allowed for this attribute exceeds current system limitations,
and the default value might be too small for some production environments. The code area
length is limited by other aspects of your system, so that the practical maximum value is
not a fixed number. Therefore, it is recommended you estimate an appropriate value for
the code area length according to the needs of your application.
