Dynamically Allocate STEPLIBs with DYNA-STEP for z/OS

Automate dynamic STEPLIB allocation and ISPF library management to save time, reduce maintenance, and save system resources with DYNA-STEP from Tone.

Using the DYNA-STEP dynamic STEPLIB solution, the TSO/ISPF configuration can be altered dynamically at any time to a new configuration, or to access any application or multiple applications. DYNA-STEP provides authorized users with efficient, direct access to multiple STEPLIBs, product versions, and DB2 subsystems, all without leaving their ISPF split screen session.

With DYNA-STEP, users work more efficiently, easily moving between environments and applications without repetitive logon and logoff activities.

The DYNA-STEP Bottom Line Advantages Include:

  • Increased user productivity
  • More efficient use of host system resources
  • Increased z/OS service levels
  • Faster application and system upgrades
  • Real Dollar Savings



As today’s mainframe shops plan and execute their z/OS upgrades and migrations, many will need to replace their TSOPLUS software, which is no longer supported by Computer Associates (CA).

DYNA-STEP Allocation

DYNA-STEP provides immediate relief for TSOPLUS users through the dynamic STEPLIB allocation capabilities that painlessly replace embedded TSOPLUS STEPLIBX allocations, and the AIA facility that transparently replaces the TSOPLUS On Demand Application (ODA) feature.

Further, DYNA-STEP delivers support for extended allocations and extensive ISPF library management capabilities, as well as a seamless TSOPLUS transition experience through straightforward TSOPLUS migration aids that eliminate the need for manual conversions.


Manage STEPLIBS and Libraries under both TSO and ISPF

Using DYNA-STEP, allocation of STEPLIB and ISPF datasets is removed from LOGON procedures, and automatically managed in product startup CLISTS and REXX EXECs, allowing fewer and more efficient LOGON PROCs.

The datasets allocated using DYNA-STEP function as actual STEPLIB datasets. Under ISPF, each logical screen may allocate separate STEPLIB datasets independently of other split screens or while at TSO READY, and each ISPF split screen may have its own dynamic STEPLIB environment. Therefore, users can execute multiple releases of an application simultaneously.

DYNA-STEP dynamically allocates additional ISPF and TSO library types such as ISPLLIB, ISPPLIB, ISPMLIB, ISPTLIB, and ISPSLIB. In addition, DYNA-STEP enables users to dynamically allocate or alter any closed TSO DD statement, providing complete flexibility to manage library and dataset concatenations on-the-fly.

Speed DB2 Maintenance and Upgrades with DYNA-STEP

DYNA-STEP enables DB2 DBAs to switch between test and production DB2 systems simply by selecting a different option on their ISPF menu, eliminating repetitive LOGOFFs and LOGONs to switch between test and production systems, and slashing the time required to upgrade and maintain DB2.

Through DYNA-STEP, allocation of key DB2 datasets, such as .SDSNEXIT and .SDSNLOAD, is removed from LOGON procedures and dynamically allocated through CLISTS and REXX EXECs, or from the TSO READY prompt. As a result, DBAs can STEPLIB to multiple DB2 systems, execute multiple DB2I sessions, and access different subsystems in one ISPF session using DYNA-STEP.

DYNA-STEP Cuts Costs & Increases Productivity

  • Reduces DASD search time and therefore, DASD contention.
  • Cuts the system I/O associated with long and repetitive DASD search options.
  • Increases DB2 flexibility, enabling DBAs to expedite migration between DB2 test and production versions.
  • Improves user service levels, speeds system response time, and delivers overall better system performance.
