The FAILDISP keyword on the CPF macro defines what the system will
do on behalf of the prefix owner when the subsystem on which the command
will be processed terminates:
If you specify FAILDISP=RETAIN, the system will keep the prefix
in the CPF table at all times, even if the subsystem owning the prefix
terminates. In this case, you can decide what to do with the command
prefix. You have three options:
Perform no action
Delete the prefix from the CPF table (REQUEST=DELETE)
Transfer ownership of the prefix to a system or subsystem in the
sysplex using the REDEFINE keyword.
If you do nothing, subsequent use of the command prefix will
cause an error message. If you redefine the owner of the command
prefix, you must update the CPF table to reflect the new owner.
If you specify FAILDISP=PURGE, the system will delete the command
prefix from the CPF table.
If you specify FAILDISP=SYSPURGE, you will need to delete the
command prefix from the table when either the subsystem owning the
command prefix goes through end-of-memory (EOM) termination, or you
remove from the sysplex the system to which CPF directs commands.
