System definition
These topics provide guidance information for designing an IMS system, including information about defining and tailoring the IMS system, IMS Common Queue Server (CQS), IMS Common Service Layer (CSL), IMS catalog, IMS Connect, IMS-to-IMS TCP/IP connections, and dynamic resource definition (DRD).
The topics also include descriptions of the IMS macros, procedures, and members of the IMS PROCLIB data set.
These topics are the same as those in the PDF publication IMS Version 15.5 System Definition, but the content in IBM® Documentation is updated more frequently.
Programming interface information
This information documents Product-sensitive Programming Interface and Associated Guidance Information provided by IMS.
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.
