Install the CKDS entry retrieval
exit by installing the load module that contains the exit into an
APF-authorized library.
ICSF uses this normal
z/OS search order
to locate the exit:
- Job pack area
- Steplib (if one exists)
- Link pack area (LPA)
- Link list (SYS1.LINKLIB concatenation)
Define the
ICSF name and the load module name on the EXIT keyword
in the installation options data set.
Parameters in the installation options data set describes
the installation options data set in further detail. The EXIT keyword
has this syntax:
- EXIT ( ICSF name, load module name, FAIL (options)
)
The
ICSF name portion of the keyword refers
to the
ICSF name for the exit. The
ICSF name for the CKDS entry
retrieval exit is CSFCKDS. The
load module name is
the name of the load module that contains the exit. The name can be
any valid name that your installation chooses. The
FAIL portion
of the EXIT keyword specifies the action
ICSF takes if the exit
cannot be loaded or if it ends abnormally. The valid FAIL options
are:
- NONE
- Do not take any action.
- EXIT
- Do not call this exit again. The exit will not receive control
during subsequent attempts at CKDS retrieval.
- SERVICE
- Fail the service. All subsequent attempts at CKDS entry retrieval
fail.
- ICSF
- End ICSF.
You must specify a FAIL option. If you do not, ICSF returns an
error message, ends abnormally, and generates an SVC dump when attempting
to load the exit. If the exit ends abnormally, the attempt at CKDS
entry retrieval fails, regardless of the FAIL option you specified.
FAIL options only apply to subsequent attempts at CKDS entry retrieval.
