Coupling Facility Configuration Options (PDF, 392KB)
Learn how configuration options for the coupling facility can make the most of resource and data sharing with improved availability and performance.
TD Bank Financial Group Best Practices (PDF, 301KB)
TDBFG is widely recognized as the “best of breed” for having achieved continuous availability since 1996 of its Parallel Sysplex and the core bank services it supports. The purpose of this Continuous Availability Best Practices paper is to provide a real life case study that proves reaching such a milestone is possible and to bring well-deserved credit to TDBFG as a worldwide leader in IT Service Management. Considering that each IT environment is unique, the TDBFG story should be as an example of what is possible, rather than as a specific roadmap for any one other organization.

Find out how coupling facility duplexing can help you manage your Parallel Sysplex and improve recovery.
Parallel Sysplex Coupling Facility Dumps
There are situations when a serialized dump of a coupling facility is required to diagnose an issue. The ability to disruptively collect a serialized coupling facility dump has always existed. A disruptive dump of a coupling facility requires the coupling facility to stop, dump and then restart. All of the structures in the coupling facility at the time of the disruptive dump were “lost” when the coupling facility restarted. With the z196, IBM enhanced first failure data capture (FFDC) with the introduction of the capability to take a non-disruptive serialized dump of a coupling facility (ND CF dump). For this type of dump, the CF image does not stop, is not restarted, and structures in the CF are not “lost.” This paper discusses Non-disruptive serialized dumps, system programmer action and how to initiate the dump.
The ITSO has created many Redbooks over the years describing Parallel Sysplex technology, installation, use, and management. These books are available for download.
OS/390 and z/OS TCP/IP in the Parallel Sysplex Environment —Blurring the Boundaries (PDF, 176KB)
Discover how TCP/IP support for the Parallel Sysplex provides high availability for the TCP/IP stack and TCP/IP applications. Focus areas include VIPA (Virtual IP Address), load balancing, use of XCF among TCP/IP stacks, and TCP/IP enhancements that can leverage the Parallel Sysplex environment.
Many applications could leverage Dynamic VIPAs and Sysplex Distributor. This white paper gives examples of five IBM middleware products which leverage Dynamic VIPAs and Sysplex Distributor, or which may be deployed with these functions for enhanced availability and workload balancing.
