    DB2 uses external authentication and as such no password file is necessary. During the database creation, DB2 automatically creates the system catalog, and when the compatibility vector is enabled, it will also create the Oracle-compatible data dictionary views and PL/SQL packages. DB2 uses ‘autoconfigure’ feature to set the variables. This course provides you with instruction on how to physically implement a logical database design in DB2. The course includes instruction on DB2 data management, DB2 catalog tables, the bind process, database utilities such as LOAD and REORG, and security considerations. Note: This course material is at the DB2 11 for z/OS level.   In Db2 11 for z/OS, we address that problem by introducing enhancements that provide a simple, transparent, and consumable approach to enabling pervasive encryption of data at rest. This same function is also available as a base release enhancement to Db2 12 for z/OS. Exam—IBM DB2 11 DBA for z/OS 3 z Use the appropriate method to alter DB2 objects z Understand the impacts of different encoding schemes Section 2: Operation and Recovery (22%) z Possess knowledge of commands for normal operational conditions z Possess knowledge of commands and utility control statements for use in abnormal conditions z Load and unload data into and from the created .

You - Selection from Subsystem and Transaction Monitoring and Tuning with DB2 11 for z/OS [Book]. The simplest form of data integrity enforcement available to DB2 is with data typing. By choosing the appropriate data types, DB2 will force columns to contain only the proper form of data (e.g., character, numeric, date).

Of course, DB2 offers more sophisticated forms of ensuring data integrity, too. DB2 uses constraints to enforce business rules for data and to help preserve database integrity. You also learned how to use both the command line and the DB2 Control Center (and how to query the database catalog) to effectively manage constraints.

Db2 Checkpoint - Db2 for z/OS Data Sharing Db2 data sharing, along with the use of IBM’s Parallel Sysplex© clustering technology, has many advantages over single, stand-alone S/© platforms.
