System administration
These topics provide guidance information for managing the administration and operations of a single IMS or one or more IMS systems that work as a unit (an IMSplex).
The topics describe designing, documenting, operating, maintaining, and recovering an IMS system, as well as the Database Recovery Control (DBRC) facility, the Extended Recovery Facility (XRF), the IMSRSC Repository, and the Repository server. The topics also include information about the IMS Base Primitive Environment (BPE), IMS Common Queue Server (CQS), and IMS Common Service Layer (CSL), all of which can be part of an IMSplex, as well as information for sharing data and message queues in an IMSplex.
These topics are the same as those in the PDF publication IMS Version 15.5 System Administration, but the content in IBM® Documentation is updated more frequently.
Programming interface information
This information documents Product-sensitive Programming Interface and Associated Guidance Information and General-use Programming Interface and Associated Guidance Information.
Product-sensitive Programming Interfaces allow the customer installation to perform tasks such as diagnosing, modifying, monitoring, repairing, tailoring, or tuning of this software product. Use of such interfaces creates dependencies on the detailed design or implementation of the IBM software product. Product-sensitive Programming Interfaces should be used only for these specialized purposes. Because of their dependencies on detailed design and implementation, it is to be expected that programs written to such interfaces may need to be changed in order to run with new product releases or versions, or as a result of service. Product-sensitive Programming Interface and Associated Guidance Information is identified where it occurs, either by an introductory statement to a section or topic, or by a Product-sensitive programming interface label. IBM requires that the preceding statement, and any statement in this information that refers to the preceding statement, be included in any whole or partial copy made of the information described by such a statement.
General-use programming interfaces allow the customer to write programs that obtain the services of IMS. General-use Programming Interface and Associated Guidance Information is identified where it occurs, either by an introductory statement to a section or topic or by a General-use programming interface label.
