Mainframe for critical applications in large organizations

Many large organizations, institutions and authorities today have business critical IT systems running in a mainframe environment. Maintenance, management and modernization of these systems can be a true challenge.

At APPER we have solid and documented experience in modernization, maintenance and further development of systems in these environments. Our industry experience is in the automotive industry, banking, finance, insurance, e-commerce, distribution, retail and manufacturing.

Our area of expertise lies within:

  • Programming
  • Analysis
  • Test and validation
  • System development
  • Project management
  • Data modeling/Data base design/DBA

in all life stages of the system:

  • New development/functionality
  • Test
  • Operation
  • System maintenance & management
  • Development & adaption

with most tools, technologies and environments, such as:

COBOL | DB2 | IMS DB/DC/TM | DL/1 | CICS | TSO | E+ | JCL – Procs – JCL Utilities | Rexx | ISPF – Skels | CA Gen | Filhantering | OPC | Endevor | VCOM | MQ | FTP/SFTP | PL/1 | Assembler | SAS mainframe | Fileaid/File Manager | Fault Analyzer | Intertest

Our maintenance team

A dedicated maintenance team can be a better option when you no longer want to manage one or more own mainframe systems “inhouse”, but at the same time feel that the system is too important and critical to export to another country, another language and maybe even another culture. We meet our customers and their businesses “IRL”; in the plant, at the customers office and / or in our office at APPER. We understand the importance of knowing our customer and understanding their business needs.

We also want to emphasize our work and our offer regarding modernization of IBM i and IBM z-systems! Many have certainly realized how well, safely and stable the existing systems and platform actually work and move forward on this platform, rather than decommission. IBM are constantly improving and investing in the technology, tools and development environments, not least through IBM’s Rational Developer (RDi / RDz). APPER is a appointed IBM Rational Partner and IBM Rational Brand Development Tools Reseller.

In many cases, companies are not fully aware of how powerful mainframe systems are in comparison to server systems, and that they are much safer.

Do you need help with modernization?

We offer a comprehensive maintenance and modernization commitment of the mainframe platform with its systems, subsystems and applications.

Together with the customer, we make a thorough analysis of the needs and of the system in question, agree on SLAs, limits of responsibility, roles, necessary contingency levels, setup times, etc., where we finally transfer the maintenance and possible further development to our maintenance team.

Our maintenance team today consists of approximately 25 consultants, who together possess more than 600 years of experience in IBM z & IBM i! We work consciously and continuously with the development of the team’s skills, and we work actively to find, educate and bring in young, driven professionals in the team.
