The DELCP function deletes checkpoint records.
After running ADADBS DELCP, the remaining records are reassigned ISNs to include those ISNs made available when the checkpoint records were deleted. The lower ISNs are assigned but the chronological order of checkpoints is maintained.
This document covers the following topics:
TODATE specifies the latest date for which checkpoint information is deleted. Checkpoint information dated after the date specified by TODATE= is not deleted. TODATE= must be specified; there is no default date. Specify the date as a four-digit decimal value for year followed by two-digit decimal values for month and day, in that order.
When an error is encountered while the function is running, the utility prints an error message and terminates with user abend 34 (with a dump) or user abend 35 (without a dump). When NOUSERABEND is specified, it must be specified as the first parameter (before all other parameters) for the utility function.
If NOUSERABEND is specified, the utility will not abend after printing the error message. Instead, the message "utility TERMINATED DUE TO ERROR CONDITION" is displayed and the utility terminates with condition code 20.
The TEST parameter tests the operation syntax without actually performing the operation. Only the syntax of the specified parameters can be tested; not the validity of values and variables. See Syntax Checking with the TEST Parameter for more information on using the TEST parameter in ADADBS functions.
All checkpoint records up to and including February 1, 1996 are to be deleted.
