Cross-reference IMS resources

You can use the cross-reference views to discover the association between databases and programs. For example, if a database is unavailable, you can easily discover the cause. The problem may be with the database or with a program that uses the database.

Cross-reference IMS resources overview

Using a preferred point of entry (database, program, or transaction), you can cross-reference resources to:

  • Investigate issues such as data unavailability
  • Assess the impact of actions against IMS resources
  • Issue actions against a database, program, or transaction

You can use the cross-reference views to discover the association between databases, programs, and transactions. For example, if a database is unavailable, you can discover the cause. The problem may be with the database, a program that uses the database, or a transaction that the associated program processes.

With cross-reference views, you can manage programs and transactions as they relate to a database, and you can manage the database itself. Before stopping a program or taking a database offline, you can use the cross-reference views to see all:

  • Transactions and programs affected by a specific database
  • Databases used by a program or transaction
  • Transactions that a program processes
  • Messages outstanding against each transaction

The cross-reference views are designed so that you can pick a preferred point of entry. If you want to view information from a database perspective, choose an IXD* view (D for database); if you prefer a program perspective, choose an IXP* view; and if you prefer a transaction perspective, choose an IXT* view. The following cross-reference views are provided:
