STEPLIB-Rx™

STEPLIB-Rx™ Delivers Extensive STEPLIB Management

STEPLIB-Rx™ enables each TSO and ISPF user to dynamically allocate and free STEPLIB datasets at any time. The datasets allocated using STEPLIB-Rx function as actual STEPLIB datasets, just as those specified in users’ TSO LOGON procedures. STEPLIB-Rx™ allows authorized users to:

  1. Automate STEPLIB allocation through startup CLISTS and REXX Execs to provide concurrent access to multiple product versions and transparent access to both test and production systems from one ISPF session.
  2. Dynamically allocate up to 128 datasets to DDNAME STEPLIB.
  3. Issue STEPLIB commands directly from the ISPF session, and allocate separate STEPLIBs in each of the 32 ISPF split screens independently of other split screens or TSO READY.
  4. Dynamically alter allocations and override standard library assignments to concurrently access multiple application versions across both test and production, to expedite testing and migration to production.
  5. Dynamically create new STEPLIBs and/or insert libraries at any position into an existing STEPLIB concatenation.
  6. Execute “Push and Pop” commands, allowing multiple STEPLIB concatenation sequences to be temporarily saved and restored anytime during the session.

Datasets allocated by STEPLIB-Rx™ are searched in the order concatenated by STEPLIB-Rx. If the member is not found in the STEPLIB-Rx specified libraries, then the LPALIB and the LINKLIST datasets are searched.

STEPLIB-Rx Options Deliver Maximum Flexibility

STEPLIB-Rx™ provides the ability to replace an existing STEPLIB environment or modify existing concatenations. STEPLIB-Rx retains library authorization and includes unit and volume operands in case the specified dataset is uncataloged. Numerous optional parameters allow authorized users to create the perfect dynamic STEPLIB environment for high productivity.

STEPLIB-Rx™ Provides Full Security

STEPLIB-Rx™ allocates standard OS partitioned datasets, allowing complete compatibility with popular security packages including CA-ACF2, CA-TOP SECRET, and RACF. This enables installations to restrict user access to libraries as STEPLIB datasets.

Test Multiple Software Versions Side by Side with the Unique STEPLIB-Rx RENT Command

STEPLIB-Rx™ enables authorized users to concurrently run multiple copies of identically named reentrant load modules, each in a separate ISPF screen. Through this unique capability, users can significantly speed upgrades of key applications and tools, such as QMF, DB2 or SAS.

Simply adding the RENT keyword to your existing STEPLIB-Rx command invocations is all it takes to gain access to multiple copies of the same load modules from different libraries on different ISPF screens. Users can then easily test new releases and multiple software versions side by side with current versions.

STEPLIB-Rx™ Fully Supports All Levels of z/OS

STEPLIB-Rx™ is certified and supports the latest z/OS operating system releases. In addition, SMP/E-based compliant installation and maintenance is provided for STEPLIB-Rx™. Further, TONE actively participates in the IBM System z ISV Program to test and certify STEPLIB-Rx™ on new IBM operating system releases before they become generally available.
