Subsystem Governance
High-performing mainframe applications depend on well-tuned database systems and transaction processors. SAI Technologies manages, tunes and upgrades DB2, IMS, CICS Transaction Server, WebSphere and IBM MQ.
The business problem
Subsystem version obsolescence, unoptimized SQL queries and fragmented CICS regions can slow performance and complicate compliance reporting.
How SAI Technologies approaches the work
Catalogue DB2, IMS, CICS and MQ instances, version dependencies and cross-platform calls.
Assign database administration, CICS region management and MQ ownership for backup, recovery, security, tuning and controlled maintenance.
Review indexing, bufferpool allocation, lock escalation and CICS thread availability.
Execute version upgrades and maintenance fixes within approved windows and validated rollback plans.
Establish continuous monitoring and governance practices for database administrators.
Illustrative industry use case
A regional bank faces transaction slowdowns in CICS and DB2 calls during morning trading hours. SAI Technologies tunes DB2 bufferpools, optimizes CICS thread limits and validates the effect on locking and response time.
A practical first SOW
Perform an in-depth health check of one DB2 or CICS environment, deliver query and transaction tuning actions, and execute approved optimization.
