SYS.1.7.A37 Parallel Sysplex in z/OS (H)

Based on the availability and scalability requirements at hand, a decision SHOULD be taken as to whether a Parallel Sysplex (a cluster of z/OS systems) is to be used and, if so, what redundancies are planned. The requirements of applications SHOULD be taken into account when planning the capacity of the necessary resources. The software and the definitions of the LPARs of the Sysplex, including RACF, SHOULD be synchronised or provided as shared files.

It SHOULD be ensured that all the LPARs of the Sysplex can access the couple data sets. The couple data sets, as well as all security-critical programs and commands for managing the Sysplex, SHOULD be protected by RACF. A GRS (global resource serialisation) network SHOULD also be set up. The hard disks of the Sysplex SHOULD be strictly separated from the hard disks of other systems. The system logger SHOULD be used with staging data sets.
