Exit XDTLC
The XDTLC user exit is invoked at the completion of data table loading—whether
successful or not. The user exit is not invoked if the data table is closed for
any reason before loading is complete. The XDTLC exit is invoked for a coupling
facility data table only if the table is loaded from a source data set.
The exit program is informed if the loading did not complete successfully—see field
UEPDTORC. This could occur, for example, if the maximum number of records was
reached or there was insufficient virtual storage. In this case, the exit program can
request that the file is closed immediately, by setting the return code.
When invoked
At the completion of table loading. It is not invoked if the loading process
was terminated because the data table had been closed.
