Today's announcement extends z Systems Parallel Sysplex leadership:

Asynchronous CF Duplexing for Lock Structures

Asynchronous CF Duplexing for Lock Structures is designed to be a continuously available solution that:

  • Makes duplexing Coupling Facility (CF) lock structures more practical, even at extended distances
  • Provides performance advantages for duplexing lock structures

Asynchronous CF Duplexing is designed to improve the performance of the duplexing of lock structures by reducing the overhead costs associated with the synchronous duplexing of lock structures while maintaining the robust failure recovery capability inherent in the redundancy of duplexing.

With Asynchronous CF Duplexing, secondary CF lock structure updates are performed asynchronously with respect to primary updates in order to drive out cross-CF latencies that exist today. This is intended to avoid the need for synchronous communication delays during the processing of every duplexed update operation.

Asynchronous CF Duplexing for Lock Structures is planned to be generally available on IBM z13™, IBM® z13s, and later z Systems generations on October 28, 2016. It requires CFCC Level 21 with service level 02.16, z/OS® V2.2 SPE with PTFs for APARs OA47796 and OA49148, CF to CF connectivity via coupling links, and exploitation. Asynchronous CF Duplexing for Lock Structures is designed to be a general-purpose interface for any transactional CF lock structure exploiters. DB2® V12 is the first exploiter.

Note: Any distance latencies associated with the round trip to and from the primary lock structure are not avoided by this support. That is unavoidable distance latency. This support is designed to avoid the additional latencies associated with the duplexing protocol itself.

Refer to the Driver 27 Customer Exception Letter for MCL bundle, PSP bucket, and latest service levels for any CFCC firmware updates.

Refer to the Software requirements section.

For more information regarding the z/OS V2.2 update, refer to Software Announcement 216-392, dated October 4, 2016.

For more information regarding DB2 V12, refer to Software Announcements 216-378, dated October 4, 2016, and 216-077, dated October 4, 2016.

IBM Electronic Services
Bottom rule

IBM has transformed its delivery of hardware and software support services to help you achieve higher system availability. Electronic Services is a web-enabled solution that offers an exclusive, no-additional-charge enhancement to the service and support available for IBM servers. These services are designed to provide the opportunity for greater system availability with faster problem resolution and preemptive monitoring. Electronic Services comprises two separate, but complementary, elements: Electronic Services news page and Electronic Services Agent.

The Electronic Services news page is a single internet entry point that replaces the multiple entry points traditionally used to access IBM internet services and support. The news page enables you to gain easier access to IBM resources for assistance in resolving technical problems.

The Electronic Service Agent™ is no-additional-charge software that resides on your server. It monitors events and transmits system inventory information to IBM on a periodic, client-defined timetable. The Electronic Service Agent automatically reports hardware problems to IBM. Early knowledge about potential problems enables IBM to deliver proactive service that may result in higher system availability and performance. In addition, information collected through the Service Agent is made available to IBM service support representatives when they help answer your questions or diagnose problems. Installation and use of IBM Electronic Service Agent for problem reporting enables IBM to provide better support and service for your IBM server.

To learn how Electronic Services can work for you, go to the IBM Electronic Support website.
