Subject:   General Availability Announcement for CA Datacom/DB for

                 z/OS Version 15.0


On behalf of CA Technologies, we appreciate your business and the opportunity to provide you with high-quality, innovative software and services.  As part of our ongoing commitment to customer success, we regularly release updated versions of our products. Today, we are pleased to announce that CA Datacom/DB, CA Datacom Datadictionary, CA Dataquery, CA Datacom SQL, CA Datacom Presspack and CA Datacom Fast Restore for z/OS Version 15.0 is now available.



New features for CA Datacom/DB and core products for z/OS Version 15.0 include:


  • Expanded use of 64-bit Memory. CA Datacom Version 15.0 customers will be able to move their Multi-User Facility (MUF) data buffer pools into 64-bit memory greatly reducing the use of 31-bit memory (which is typically a limited resource in z/OS environments). With the movement of the data buffer pools, the majority of MUF memory usage can now be directed to 64-bit memory.


  • Ability to add/delete an index online. CA Datacom Version 15.0 provides a set of enhancements that allows you to remove unused indexes or add new indexes without a user data access outage. The process provides a series of steps that allows you to disable a key to applications (while still maintaining its validity) so that a trial period can be completed before the physical delete is actually done. Likewise, you can build a new index before making it available to existing applications. 


  • Dynamic extension of VIRTUAL Database Areas.  CA Datacom Version 15.0 provides you with the ability to extend a Virtual database area dynamically while the area is in use by a MUF. This functionality allows you to avoid MUF outages when a critical Virtual data area becomes full. 


  • Parallel Variable Log Area (LXX) Support of Large Rows.  CA Datacom Version 15.0 has expanded the largest allowable row size for logging from just under 16K to the maximum allowable row size (32720 bytes).


  • SQL Source Cache. CA Datacom Version 15.0 introduces the new SQL Source Cache which provides significant performance improvement and tuning of ODBC/JDBC applications executing through CA Datacom Server. The bind process is avoided when the statement, after eliminating literals, is found in the Cache.  Execution performance statistics are collected and can be used to find/abort inefficient queries, or analyze specific queries using the new QUERYNO clause.


  • Additional SQL Syntax.  CA Datacom Version 15.0 delivers additional SQL language syntax including the new CREATE DATABASE and CREATE AREA statements. You can combine these statements with the existing SQL syntax to define the Datacom database model.


  • Enhanced Performance.  CA Datacom Version 15.0 delivers various performance enhancements including parallel restart processing for quicker MUF restarts (after a failure), improved OPEN/CLOSE processing, and enhanced performance of DBUTLTY functions such as the REPORT function with TYPE=DATASP.



We also encourage you to visit the CA Datacom product information page on the CA Support Online website at for more information.  Please refer to the CA Datacom Release Notes for a complete list of the enhancements and benefits for this release.
