Senior Application Database Administrator: RDBMS (w2 Role)
Senior Application Database Administrator: RDBMS
An IBM Db2 z/OS Application Database Administrator responsible for configuring and
managing Q Replication using the IBM InfoSphere Data Replication (IIDR) suite requires
expertise in several key areas, including database administration, and replication
technologies. Here's a summary of the essential skills:
- IBM Db2 for z/OS Administration
• Strong understanding of Db2 for z/OS architecture, storage structures, and system
performance tuning.
• Proficiency in Db2 system parameters, logging, backup, and recovery strategies.
• Experience with Db2 utilities (e.g., REORG, RUNSTATS, COPY, RECOVER).
• Knowledge of SQL tuning and optimization for Db2 on z/OS.
- IBM InfoSphere Data Replication (IIDR) & Q Replication
• Deep understanding of IBM Q Replication concepts, including unidirectional and
bidirectional replication.
• Configuration and tuning of Q Capture and Q Apply programs.
• Managing spill queues, latency monitoring, and troubleshooting replication lag.
• Knowledge of MQTs (Materialized Query Tables) and staging tables for replication.
- Performance Tuning & Troubleshooting
• Using IBM InfoSphere Replication Dashboard to monitor Q Replication.
• Analyzing latency, log processing rates, and MQ message throughput.
• Tuning buffer pools, MQ queue sizes, and commit frequency for optimal performance.
• Diagnosing latency issues, queue buildup, and replication bottlenecks.
- Scripting & Automation
• Writing Rexx, or JCL scripts to automate replication tasks.
• Using IBM Data Studio, IBM Admin Tool, and DSNTEP2/DSNTEP4 for queries and
automation.
• Experience with SMF records and Db2 performance traces for diagnostic purposes.
