Senior Mainframe Associate

We would need a senior Mainframe experienced associate with extensive knowledge in

IMS, DB2, CICS PL1, COBOL, JCL and MQ. Proven experience in real-time and batch programming environments

Location : Denmark/Poland (Warsaw)

Key Responsibilities:

IMS to DB2 Bridge & Data Propagation

• Design and develop enhancements to the bridge responsible for asynchronous data propagation between IMS and DB2.
• Read and interpret IMS logs to identify updated rows and translate them into executable SQL commands on DB2.
• Ensure data integrity and consistency across IMS and DB2 systems.
• Maintain and optimize PL/I programs for complex data transformation and synchronization.

IMS Realtime Logic & Data Modeling

• Maintain and evolve the IMS data model in a real-time environment.
• Analyze and implement load balancing strategies for transactions across physical IMS tables.
• Collaborate with DBAs to calculate storage requirements and evaluate consumption for new and existing tables.
• Modify COBOL applications using IMS APIs to support logical load balancing and performance improvements.
• MQ messaging for real-time transaction handling and inter-system communication.
• Troubleshoot and resolve performance bottlenecks across mainframe components.

Additional Experience

• Application enhancements or creation of new IMS databases.
• Proven incident handling and resolution capabilities.

Competencies:

• IMS DBA level knowledge.
• Calculate storage needs for new tables.
• Evaluate current consumption on existing tables.
• COBOL application IMS API.
• Make changes to the logical load balancing between our IMS tables.
• PL1 programming, highly skilled, complex technical solution.
• IMS on a technical level not only application API, the bridge programs also scans the IMS logs to find insert operations, so an understanding of the IMS logs is needed.
• Experience in cards and payments will be an added advantage.
