Performance enhancements for lock structures with record data z/OS MVS Setting Up a Sysplex SA23-1399-00 |
|
z/OS® V1R4 and APAR OW52437 provide performance improvements for lock structures with record data in a system-managed CF structure duplexing environment. Compatibility for the improvements is available for systems in the sysplex at OS/390® V2R8 and higher through APAR OW52266. The performance improvements may increase the size of an existing lock structure; perhaps an additional 300K of space in the coupling facility may be required. Currently allocated lock structures with record data must be reallocated through the rebuild process to acquire the additional storage in preparation for system-managed CF structure duplexing. The following procedure outlines the steps to provide compatibility
for the performance improvements.
The following procedure outlines the steps to enable the lock structure
performance improvements provided in OW52437.
