This single-day course introduces the changes and new features of Db2 12 for z/OS. It provides a technical overview, and discusses areas of potential advantage for the new features, as well as caveats and potential problems with new features.

On successful completion of this course attendees will be able to:

• describe the new features and facilities introduced with Db2 12;
• know the migration possibilities;
• identify the changes to SQL, commands, utilities and infrastructure relevant to their organisation;
• identify the new features that would particularly benefit their own installation.

• New SQL Possibilities

  "Advanced triggers" having a full SQL PL body; arrays as global variables; enhanced MERGE statement; DML pagination: OFFSET clause, multi-column predicates; piece-wise DELETE; new OLAP functions (e.g. LISTAGG)

• Performance Enhancements

  New faster insert algorithm; automated RUNSTATS runs; optimizer improvements (e.g. for UNION ALL, outer joins, temporal queries, top-n pushdown; adaptive list prefetch); new access paths (e.g. adaptive index and bubble up)

• Availability Enhancements

  Transfer ownership of: database, tablespace, table, index, view, stogroup; partition sizes up to 1TB; RTS & some catalog tables can be made temporal

• Infrastructural Changes

  Unicode columns in EBCDIC tables; referential integrity for temporal tables; 7-byte RIDs; relative page numbering for partitioned tablespaces; DSSIZE at partition level

• Security Enhancements

  Optional obfuscation ("wrapping") of the body of an SQL PL procedure, trigger, or function; UNLOAD privilege; resource limit facility for static SQL

• XML Enhancements

  XMLMODIFY can now update multiple documents and use the FLWOR notation; enhancements to the functions XSLTRANSFORM and JSON_VAL

• Command and Utility Changes

  New commands (related to function level, to dynamic statement cache, and to statistics collection)

• Migration Considerations

  Simplified migration process: gradually enabling new features through "function levels" and continuous delivery.
