Mainframe services

ITF consult can assist with:

  • Design and architecture on hardware and software
  • Building robust and resilient solutions for critical applications
  • Technical program maintenance and development
  • Translating business requirements into technical solutions
  • Performance optimisation and fine tuning of system capacity
  • Optimize software usage

Mainframe design for resilience.

Failure tolerant systems are designed to be able to contain errors and continue operation without interruption. Services offered to enable the process:
  • Disaster recovery infrastructure architecture and design
  • Failure analysis and root cause analysis reviews
  • Parallel Sysplex design for continued operation

Experience

Working with resilience in a 50000+ Mips Parallel Sysplexes

Creating fault tolerant implementations of application systems

Technical lead on disaster recovery decision planning and creation of a pre-approved plan

Technical programming

Programming of technical routines from small analysis software to larger scale monitoring solutions.

System software exits for MQ, CICS, JES. SMF analysis tools for performance analysis and root cause analysis. Monitor routines to catch resource constraint situations.

Experience:

- System health checker routines

- Hardware instrumentation analysis program

- Rexx, Assembler, C/C++, Cobol, JCL

Mainframe modernisation

Using mainframe when best fit for purpose and making data and core systems available thru web-services and api's.

Modernising on the mainframe makes sense as the core applications will remain in the proven and well performing environment. Modernising to make data and functions available to any strategic software portfolio makes good sense.

Experience:

API enabled core mainframe systems

Web services in CICS

Using certificates for secure and encrypted connections

Ansible scripts for process automation

Performance and Capacity

Performance and capacity goes hand in hand. Optimal performance is the driver for optimal capacity. Sufficient capacity is the driver for overall well performing systems.

Capacity planning and a firm hand on performance is the key to a cost optimal system.

Experience:

Tools like APA, Strobe, RMF, SMT-ITBI, Thruput Manager and several homegrown

Application tuning including LE tuning in CICS and batch

Managing both 4-hour rolling average as well as Tailored Fit Pricing on IBM software

Software stack optimisation

Demise or replacement of system software for cost savings and simplifications.

Software creates affinities that will increase dependency on the specific product to operate the systems. Analysis to find and eliminate dependencies is required to successfully demise or replace the software.

Experience:

Analysis of data, logs and SMF records to identify dependencies that need to be addressed

Demise of vendor software to optimize the software stack for cost
