Frequently asked questions
Can you take full responsibility for mainframe application maintenance?
Yes: incidents, evolutions, packaging and production window coordination, with up-to-date documentation.
Do you optimize batches exceeding their window?
Yes. We trace the chains, identify bottlenecks (I/O, JCL exclusions, DB2 contention) and restore the SLAs.
How do you open a mainframe to modern systems?
Through controlled integration points: APIs, MQ queues, ETL or replication — without threatening production stability.
Can you modernize without a big bang?
Yes, in stages: batch takeover, service opening, then targeted migration to the cloud or a distributed environment.
Is the team available during production windows?
Yes, the Paris/Tunis setup is sized around your batch windows and your monthly or quarterly milestones.
