AR/CTL products

You can use the following AR/CTL products to meet the needs of application programs that run in the z/OS system environment:

AR/CTL for IMS

AR/CTL for IMS works independently in application programs that use only IMS databases, only sequential files, or both. AR/CTL for IMS works with AR/CTL for VSAM in programs that use IMS databases and VSAM data sets. These programs can also use sequential files.

AR/CTL for IMS works with AR/CTL for Db2 in programs that use Db2 tables, IMS databases, or the Db2-oriented services of AR/CTL (explained later in this section) in an IMS environment. These programs can also use sequential files. However, AR/CTL for IMS can work alone with programs that use Db2 tables and IMS databases but do not use Db2-oriented services of AR/CTL.

AR/CTL for Db2

AR/CTL for Db2 works independently in application programs that use only Db2 tables, only sequential files, or both. AR/CTL for Db2 supports the use of Resource Recovery Services Attachment Facility (RRSAF) in an AR/CTL non-IMS environment. When RRSAF is used in an AR/CTL non-IMS environment, AR/CTL for Db2 invokes the Resource Recovery Services routines to perform both commit processing and backout processing. Using Resource Recovery Services commit services and backout services ensures that all the participants of the Resource Recovery Services unit-of-work remain synchronized (for example, for Db2 and MQ).

AR/CTL for Db2 works with AR/CTL for VSAM in programs that use Db2 tables and VSAM data sets. These programs can also use sequential files.

AR/CTL for Db2 works with AR/CTL for IMS in programs that use Db2 tables, IMS databases, and Db2 oriented services of AR/CTL in an IMS environment. These programs can also use sequential files.

AR/CTL for VSAM

AR/CTL for VSAM works independently in application programs that use only VSAM data sets, only sequential files, or both. AR/CTL for VSAM works with AR/CTL for Db2 and AR/CTL for IMS in any program that uses VSAM data sets. These programs can also use sequential files.

You can use the AR/CTL products separately or together to provide services for application programs that use the following types of data structures:

  • Sequential files, using queued sequential access method (QSAM)
  • IBM Db2 tables
  • IBM IMS full-function, Fast Path, or GSAM databases
  • Virtual storage access method (VSAM) data sets
  • Any combinations of these data structures
