Simple, dynamic system management.

NIM offers maximum benefits to organizations using:

  • z/OS, MSP EX or similar
  • VTAM
  • JES2 or JES3
  • and wish to avoid using a cumbersome general purpose TP monitor.

NIM is designed to make full use of the sub-tasking and memory management capabilities of z/OS, whilst interposing a minimum of activity between NATURAL, VTAM and ADABAS.

NIM establishes a new OS subtask for each user, allocating a unique address range in NIM’s virtual address space. Therefore each user is independent and any user sub-task essentially isolating each user and can’t affect other users. By using only the documented z/OS interfaces, NIM remains transportable through OS upgrades. NIM does not need to run as an authorized program (but can), so protected areas of memory are not threatened.

NIM advantages:

Reduced resource overhead:

NIM will consume between 1% to 5% of the CPU used by NATURAL sessions.

Minimal support required:

Typically no dedicated support responsibility is required.

Ease of Use:

NIM’s logical and convenient DBA interface means simple installation, minimum training and quick response to environment changes.

System Performance:

NIM’s powerful monitoring and control facilities provide an opportunity for system tuning and the potential to improve resource utilization and cut response times.


An elegant and logical architecture has resulted in an exceedingly stable, low maintenance product.


The value of NIM in the areas of processing efficiency and reduced support costs guarantees return on investment within a brief period.
