AUDSERV is only used in an SQL environment. It is not an interactive program; it is invoked by the NonStop TMF subsystem. AUDSERV makes it possible for applications to share the use of a table or index during DDL reorganization.
AUDSERV is invoked when re-organization work is happening concurrently with normal data access. Splitting a partition is one situation where this can occur. When a partition is split, it takes some time for the rows in the table to be physically copied from one partition to another and then be deleted from the first partition. During this time, data access is suspended . If the partition is split while the application is running, AUDSERV interleaves the data access and reorganization functions, keeping track of all the " suspense " NonStop TMF audits generated by the data access and then applying them during the "commit" phase. This way, only a short table lock is needed to mark all the "suspensed" data changes being held in NonStop TMF software as applied. If applications couldn't share operations, then all user access would be locked out for the duration of the data reorganization.
RISK AUDSERV has no risk associated with user intervention.
BP-FILE-AUDSERV-01 AUDSERV should be secured "UUUU".
BP-OPSYS-LICENSE-02 AUDSERV must be LICENSED.
BP-OPSYS-OWNER-02 AUDSERV should be owned by SUPER.SUPER.
BP-OPSYS-FILELOC-02 AUDSERV must reside in $SYSTEM.SYSTEM.
If available, use Safeguard software or a third party object security product to grant access to AUDSERV only to users who require access in order to perform their jobs.
BP-SAFE-AUDSERV-01 Add a Safeguard Protection Record to grant appropriate access to the AUDSERV object file equivalent to the Guardian file security string listed above.
