Updating XCF initialization options
This section is useful if you use XCF for communication.
XCF initialization options
are specified in the COUPLEnn member
of SYS1.PARMLIB. If you have not specified your own COUPLEnn member,
the system uses the default member, COUPLE00. The IBM-supplied COUPLE00
member causes the system to be IPLed in XCF-LOCAL mode. This mode
is not supported by HCL Workload Automation for Z.
So ensure that
your system uses a COUPLEnn member that
does not IPL the
system in XCF-LOCAL mode. The COUPLEnn member
must include
the PCOUPLE keyword of the COUPLE statement. If this is omitted, XCF
is initialized in XCF-LOCAL mode. For HCL Workload Automation for Z purposes,
you can use
the default values for the remaining XCF options.
COUPLEnn example
COUPLE SYSPLEX(PLEX1) /* SYSPLEX name */
PCOUPLE(PLEX1.COUPLE1) /* Primary couple data set */
ACOUPLE(PLEX2.COUPLE2) /* Alternate couple data set*/
MAXMSG(2000) /* No of 1k message buffers */
CLASSDEF CLASS(DEFAULT) /* Default transport class */
CLASSLEN(956) /* Message length */
GROUP(OPCGRP,OPCDS) /* OPC Group names */
PATHIN DEVICE(cccc,dddd)
PATHOUT DEVICE(aaaa,bbbb)
PATHIN STRNAME(str1,str2) CLASS(DEFAULT)
PATHOUT STRNAME(str1,str2) CLASS(DEFAULT)
Issue
the console command
"D XCF,CLASSDEF,CLASS=ALL" to see if you already have a DEFAULT class
(the name of this class might be something other than DEFAULT) having
CLASSLEN(956), which is the default value. If there is such a class,
you just need to add the TWS specific GROUP names (OPCGRP,OPCDS) to
the CLASSDEF statement for that CLASS, as shown in the example above.
Note: By specifying MAXMSG(2000) on the COUPLE statement,
as shown
above, all transport classes will use this value unless a different
value is specified at the CLASSDEF level. MAXMSG(2000) is the default
value.
If XCF is used to connect the Data Store to the controller, a specific XCF group must be defined, and it must be different from the one used to connect the controller to the z/OS® tracker. These two separate XCF groups can use the same XCF transport class.
Note: You can change XCF options while the system is
active by using the SETXCF operator command.
