The DELPLOG function allows you to dynamically delete a protection log (PLOG) data set without terminating your current nucleus session. PLOG data sets can also be dynamically deleted using an equivalent function in the Adabas Online System (AOS).
Note:
Any PLOG data sets you delete dynamically may reappear once you
recycle your Adabas nucleus. To ensure the PLOG data set is dropped when Adabas
is stopped and restarted, alter the Adabas startup JCL as well, ensuring that
the NPLOG ADARUN parameter setting is
reduced to account for the dropped PLOG data sets.
Running the ADADBS DELPLOG utility function is invalid when Adabas is running with dual PLOGs.
This document describes the syntax, processing, and parameters of the ADADBS DELPLOG function.
Use the NUMBER parameter to specify the number of the nonsequential PLOG data set to be deleted. Valid values are integers ranging from "2" through "8" (inclusive).
This parameter is required only in cluster environments.
Use the NUCID parameter to specify the nucleus ID of the Adabas within the cluster to which the PLOG data set should be dynamically deleted.
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. Note that the validity of values and variables cannot be tested: only the syntax of the specified parameters can be tested. See Syntax Checking with the TEST Parameter for more information about using the TEST parameter in ADADBS functions.
In the following example, PLOG data set 3 is dynamically deleted from its 3390 device.
ADADBS DELPLOG NUMBER=3,CLOGDEV=3390
In the following example, PLOG data set 6 is dynamically deleted for the Adabas nucleus 65590 in a cluster environment.
ADADBS DELPLOG NUMBER=6,NUCID=65590
