This course is intended for z/OS system administrators, database administrators, or other technical individuals who will be managing Db2 12 for z/OS.

• Understanding of the objects (such as databases, table spaces, tables, indexes, and so forth) used in a Db2 subsystem
• Basic knowledge of SQL
• At least one year as a z/OS systems programmer or equivalent knowledge

OR

• At least one year as a Db2 for z/OS Database Administrator

After completing this course, students should be able to:

• Describe the components and address space structure of a Db2 subsystem
• Explain the use of RACF (or another external security program) for Db2 connection security
• Explain the use of Roles and Trusted Contexts
• Implement security procredures for a Db2 subsystem
• Explain Db2 program flow for all environments
• Explain parameter setting for the IRLM
• Invoke and utilitze Db2 TSO facilities
• Use the Db2 Catalog to monitor subsystem authorizations
• Work with the Active Log data sets
• Explain Db2 logging
