DB2 10 for z/OS System Administration

The course is updated for DB2 10 for z/OS. This course is the classroom delivered version of the Instructor led Online course DB2 10 for z/OS System Administration - ILO (3V851).

Administrators of DB2 10 for z/OS can acquire a view of the architecture and fundamental processes required to manage a DB2 10 for z/OS subsystem. Engage in lectures and hands-on labs to gain experience to:

Relate the z/OS IPL process to a DB2 subsystem
Explain effects of stopping and starting DB2
Explain how DB2 sets and use Integrated Catalog Facility (ICF) catalog names
The use of DSN command processor running in batch and foreground
Use views to minimize your ability to see into the DB2 catalog
See how the catalog (through grant activity) controls access to data
Search the catalog for problem situations
Use the catalog and DB2 utilities to determine data recovery requirements
Describe Internal Resource Lock Manager (IRLM) in a DB2 environment
Implement DB2 and Resource Access Control Facility (RACF) security
Describe DB2 program flow for all environments
Display normal and problem threads and database status
See how the SQL Processor Using File Input (SPUFI) AUTOCOMMIT option defers the COMMIT/ROLLBACK decision
Interpret lock displays
Identify and cancel particular threads
Describe available DB2 utilities to manage system and user page sets

This intermediate course is for system administrators, database administrators, and other technical individuals, who manage and implement DB2 10 for z/OS.

Conocimientos requeridos

You should have an understanding of the objects (tables, indexes, databases, and so forth) used in DB2 systems, and of how those objects are created, managed, and recovered.

These skills can be developed by taking the DB2 Database Administration Workshop (CF83) / DB2 9 for z/OS Database Administration Workshop Part 1 (CV830) or through equivalent experience. You should also have a working knowledge of SQL. The DB2 SQL Workshop (CF12) / SQL Workshop - Instructor Led Online (3E120) provides that.

In addition, you should have:

At least one year as a z/OS systems programmer orequivalent experience
Or, one year working with DB2 on the mainframe as a DBA on the mainframe or equivalent experience
