Resource management install and discard exit XRSINDI
The XRSINDI global user exit is driven, if it is enabled, immediately after CICS
successfully installs or discards a resource definition.
The install and discard activities that drive the exit are as follows:
v The install function of the group list on an initial or cold start of CICS
v The CEDA INSTALL command
v All autoinstall operations, as follows:
– The autoinstall of a terminal, connection, program, mapset, partitionset, or
journal
– The automatic discard of an unused terminal, controlled by the AILDELAY
system initialization parameter and the SIGNOFF parameter on the
TYPETERM resource definition.
v The connection to, and disconnection from, an MVS log stream
v A CEMT DISCARD and EXEC CICS DISCARD command
v The front-end programming interface (FEPI) install and discard operations: the
EXEC CICS FEPI INSTALL command and EXEC CICS FEPI DISCARD
command.
The parameter list is designed to pass the names of more than one resource
installed or discarded, in field UEPIDNAM. When designing your global user exit
program, do not assume that the number of resource names passed is always one.
You are recommended to analyze the resources within a loop based on the value
referenced by UEPIDNUM.
Note that the names of modegroups are prefixed with the corresponding connection
name. There is no separator between the two names: the first four characters form
the connection name, followed by eight characters for the modegroup. The parts of
the concatenated name are fixed length—if connection names are defined with less
than four characters, they are padded with blanks in the concatenated names.
Similarly, the connection names for a front-end programming interface (FEPI)
connection is a concatenation of a FEPI node name and a FEPI target name, each
of which is 8 characters long (fixed length) with no separator.
The exit is driven once for each individual resource in a group list installed during a
CICS initial or cold start. If you are concerned about the performance overhead on
an initial or cold start, do not enable the exit until after the group list is installed. To
obtain the information about resources installed prior to enabling the exit, you can
write a program to scan the tables of installed resources, using the EXEC CICS
INQUIRE
resource_name
browse function.
