Overview of the Automated Operator Interface
The AOI works during the authorization and/or allocation and unauthorization and/or deallocation of the database.
It provides positive control over the database because it always waits until the command completes successfully before initiating further processing.
When the utility is operating with DBRC active in a SHARECTL environment, it must obtain authorization from DBRC before accessing the data set group or area. If the IMS or DBCTL system is active at the same time that the utility is running, the authorization request may fail. For example, if the IMS system is active and is holding a database in update mode, DBRC rejects the request from the utility for read-with-integrity access mode to that database. Before the utility can continue, the database access mode that is held by the IMS system must be changed. This task can be accomplished by manually entering the appropriate UPDATE, /DBD, or /DBR command, or it can be accomplished automatically by invoking the AOI.
You can implement the AOI with the following methods, which are identified by the utility keywords that control them:
- PLEXNAME
- AOI(B)
- AOI(Y)
