Example 10: CHECK DATA for user-defined RI using saved rules

In this example, CHECK PLUS checks for the specified constraint only. SCOPE ALL is specified to allow for checking of user-defined RI. The user-defined RI rules specified in the example 8 job were saved in the CHECK PLUS RI rules tables and the utility automatically uses the rules in this job.

CHECK PLUS reports five violations in message BMC52288I and details the errors in messages BMC52610I and BMC52611W. Because of these errors, the utility completes with return code 4.

Message 50041I indicates the status of zIIP processing. For this example, the ZIIP installation option is ENABLED, but an XBM subsystem was not specified. CHECK PLUS automatically located an available XBM subsystem to provide zIIP processing.

CHECK PLUS writes five foreign keys in violation to the SQLDEL-formatted discard data set. The SQL DELETE statements can be executed to delete the rows that are in violation. You can use SPUFI, QMF, DSNTEP2, DSNTIAD, or the SQL batch execution program that CHECK PLUS provides. See SQL-batch-execution-program for detailed information about this program and an example execution.
