Db2 support

This version of REORG PLUS supports IBM Db2 Versions 12 or later.

System and software requirements

The REORG PLUS product has the following requirements:

  • This version of REORG PLUS has the following system requirements:
    • IBM System z10 processor or a later 64-bit z/Architecture processor
    • Minimum hardware EC12 and Z114
    • z/OS version 2.4
  • REORG PLUS requires a minimum of the following versions of BMC common components:
    • Version 2.4.01 of BMCSORT
    • Version 13.1.00 of the Db2 Utilities Common Code (D2U)
    • Version 13.1.00 of the Db2 Solution Common Code (SCC)
  • To update Db2 catalog statistics or the DASD MANAGER PLUS for DB2 database statistics tables, REORG PLUS requires a minimum of version 13.1.00 of the BMC Common Statistics component.

  • To use the Instant Snapshot technology, REORG PLUS requires version 6.2.01 or later of the BMC SNAPSHOT UPGRADE FEATURE (SUF) (also known as XBM) product and its technology.

    For Db2 V13 support, XBM PTF BPE0556 is required. If you use the XBMID option to specify a particular SUF (also known as XBM) subsystem, that subsystem must be at this maintenance level. If you do not specify a particular SUF (also known as   XBM) subsystem and snapshot processing is required, REORG PLUS searches for an SUF (also known as   XBM) subsystem at this level.

  • To offload eligible processing to an IBM z Integrated Information Processor (zIIP), REORG PLUS requires version 6.2.01 or later of SNAPSHOT UPGRADE FEATURE (SUF) (also known as XBM).

    If you use the XBMID option to specify a particular SUF (also known as XBM) subsystem, that subsystem must be at this maintenance level. If you do not specify a particular SUF (also known as XBM) subsystem and ZIIP ENABLED is in effect, REORG PLUS searches for an SUF (also known as XBM) subsystem at this level.

  • To use any features that invoke DSNUTILB, you must be licensed to use the IBM Db2 REORG utility.

Required authorization

Using the REORG PLUS product requires that you have the appropriate authorization within Db2 and through your system security package, such as RACF. You need sufficient authorization to access resources and perform specified tasks during REORG PLUS processing.

The products use one of the following mechanisms to verify authorization:

  • If the Db2 DSNX@XAC authorization exit is available for your system, the product uses this exit to verify authorization for external access. The exit is available from the following sources:

    • IBM provides a sample exit with Db2 for the IBM Resource Access Control Facility (RACF) component.
    • CA Technologies provides the DSNX@XAC exit with the CA-ACF2 and CA-Top Secret products.

    We recommend this mechanism for implementing external security. The access control authorization exit must be available in the STEPLIB, JOBLIB, linklist, or in the SYS3.DSN exit.

  • If the DSNX@XAC exit is not available, the product uses the standard Db2 method to check security.
