Mainframe Service

Best Practices to Right-size Consumption

CPU Hours

  • Maintain, optimize, and/or tune applications to increase efficiency of DB2 and CICS code.
  • Review and optimize frequency and scheduling of batch jobs.
  • Review rebinding SQL code in new version of DB2 optimizer.
  • Consolidate applications and CICS environments to lower CICS region management costs.
  • Long term: Migrate application code to servers where applicable and use mainframe as a database server to use less costly zIIP engine.
  • Consider hiring a third party to maintain, tune, and optimize applications and databases.

Storage and Backup

  • Review and optimize storage capacity.
  • Review retention of backups and eliminate redundant backups.
  • Implement agency data retention plan for long-term data storage.
