System  requirements

This topic describes the Fast Path Recovery Utility system environment, system requirements, and program considerations.

System Environment

Fast Path Recovery Utility requires the following system environment:

  • Fast Path Recovery Utility programs and macros run on any CPU that is compatible with the IBM z/Architecture (as outlined in the z/Architecture Principles of Operation).
  • Fast Path Recovery Utility programs operate under any version of MVS/XA and MVS/ESA. All input/output operations use QSAM, BSAM, and VSAM.
  • Fast Path Recovery Utility programs run in a virtual storage region. Region size for TSSAFR1 (Selection and Extract Processing) is approximately 2048 KB, which includes the requirements for the program, access method modules, and buffers. TSSAFR2 (DEDB Recovery) requires a virtual storage region of approximately 2048 KB.

System resources

Fast Path Recovery Utility requires the following system resources:

  • Hardware:
    • Fast Path Recovery Utility operates on any processor that supports the MVS/ESA operating system. It requires the same hardware as the IBM IMS/ESA Database Manager product.
    • BMC licenses each product to run on a specific CPU.
  • Operating system:
    • You can use Fast Path Recovery Utility with the IBM z/OS operating system.
    • Fast Path Recovery Utility is written in assembler language within the constraints of the OS/VS Assembler.
  • IMS:
    Your site must have a license for the IMS/ESA Database Manager. You can use Fast Path Recovery Utility with the following versions and releases of IMS:
    • IBM supported versions of IMS
    • All releases of DBRC

Program considerations

When using Fast Path Recovery Utility, consider the following:

  • Fast Path Recovery Utility programs and associated utility modules are written in assembler language. They do not require source code modifications to any user or IMS module or control block.
  • APF authorization is required only for block-level sharing support.
  • Fast Path Recovery Utility requires the following programs for installation, operation, and maintenance:
    • z/OS
    • Fast Path Recovery Utility supports all IBM-supported versions of z/OS and will support new versions as they become available from IBM.

    • IMS/ESA

      Fast Path Recovery Utility supports all versions of IMS/ESA and will support new versions as they become available from IBM



      • OS/VS utility programs
      • OS/VS linkage editor
      • OS/VS access method services
      • (Optional) IBM supported versions of DB2
