- DB2 log
- Catalog and directory
- Data sharing feature
- Connection process
- Command routing process
- Program preparation and execution processes
- Transaction and points of consistency
- Set up and tune the IRLM
- Recognize the important IRLM parameters
System security
- Protect DB2 data sets when DB2 is up or down
- Protect connections to DB2
- Describe the high-level operation of DB2 security exits

Operations (monitoring and controlling DB2)
- Monitor and control DB2
- Train operators at your local site
- Discuss the functions of ATS (Administrative Task Scheduler)
System recovery/restart
