CICS Transaction Gateway V5 The WebSphere ... - IBM Redbooks

► AUTH_USERID_PASSWORD
This operand determines whether the user ID and password sent on an ECI
call should be verified by RACF before the EXCI call is made. The default is
YES. We did not wish to flow user IDs on the ECI calls in our tests, and
therefore left this line commented out in our ctgstart script, ctgenvvar &
STDENV member.
Tip: The way CICS TG checks AUTH_USERID_PASSWORD is unusual.
While MVS checks to see the contents of a variable, the CICS TG ignores the
contents of this variable and merely checks if it is null or not null.
AUTH_USERID_PASSWORD can be YES, NO, or REDRUM and it is still
considered set (not null).
To unset a variable, comment it out in ctgenvvar and your STDENV member,
and make sure it is not set in /etc/profile or the .profile of the user ID under
which the CICS TG is running.
► EXCI_LOADLIB
This is the name of the library containing the EXCI load modules, without its
high-level qualifier. This will usually be SDFHEXCI, and so does not usually
need modifying.
► EXCI_OPTIONS
This is a user library that contains the EXCI options to be used if you have a
tailored version of the EXCI options table (DFHXCOPT). For more details,
refer to Chapter 6, “CICS TG security scenarios” on page 99.
► HLQ
This is the high-level qualifier for the library specified in EXCI_LOADLIB. If
you do not have your CICS installation image in the default location
CICSTS22.CICS, then you will need to modify this statement.
► CICSCLI
You can specify a different path to the configuration file by setting the location
of CTG.INI. This variable is instrumental in running multiple CICS TG started
tasks.
You will note in our example that we point the CICS TG to a directory specific
to the started task. This allows each CICS TG started task to have its own
CTG.INI.
► CTG_CLASSPATH
This controls the classpath used by the Gateway daemon. It is best set in
ctgenvvar, and needs modifying only if you need to make a server
compression class available to a protocol handler. This will be the case if you
