CA Datacom/AD for CA 7 › Database Sizing › Multiple CA 7 Instances in a Single MUF

Multiple CA 7 Instances in a Single MUF

Some users want to put multiple CA 7 instances in the same MUF. If you do, make the space allocations for the CA Datacom/AD data areas reflect this requirement. You can handle this requirement in several ways:

• Create export files for all instances and concatenate them when running the space estimator.

  Note: You can create an export file for an instance that is already running CA 7 Version 12.0. Use the Database Export Import utility. See CAL2DBEI Utility in the Systems Programming Guide.

• If the allocations for the first instance are adequate, you can manually adjust the allocations based on the relative size of subsequent instances. Adjust them to the size of the first instance.

Dynamic Extend

The database is defined using the Dynamic Extend feature. This feature causes the index and data areas to extend up to 15 times per volume automatically. They extend when the allocated space is exhausted. When data areas are defined into a DFSMS storage group, the extents can be to any volume in that group.
