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 a parameter error or a functional error occurs while this utility function is running, the utility ordinarily prints an error message and terminates with user abend 34 (with a dump) or user abend 35 (without a dump). 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.
Note:
When NOUSERABEND is specified, we recommend that it be specified
as the first parameter of the utility function (before all other parameters).
This is necessary to ensure that its parameter error processing occurs
properly.
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.
