Title

ACP database is not on a separate physical volume from its backup and recovery datasets. (Cat II impact)

Discussion

The ACP backup and recovery data files provide the only means of recovering the ACP database in the event of its damage. In the case where this damage is to the physical volume on which it resides, and any of these recovery data files exist on this volume as well, then complete recovery of the ACP database would be extremely difficult, if even possible.

Fix Text

The systems programmer will ensure that placement of ACP files are on a separate volume from its backup and recovery data sets to provide backup and recovery in the event of physical damage to a volume. Identify the ACP database(s), backup database(s), and recovery data set(s). Develop a plan to keep these data sets on different physical volumes. Implement the movement of these critical ACP files. File location is an often overlooked factor in system integrity. It is important to ensure that the effects of hardware failures on system integrity and availability are minimized. Avoid collocation of files such as primary and alternate databases. For example, the loss of the physical volume containing the ACP database should not also cause the loss of the ACP backup database as a result of their collocation. Files that will be segregated from each other on separate physical volumes include, but are not limited to, the ACP database and its alternate or backup file.
