Add or Edit a Coupling Facility Structure
Add or edit information for a coupling facility structure. (The CFRM policy
contains control information about the coupling facility and the structures
you define.)
The Parallel Sysplex wizard creates the following structures:
-
IXCPATH1 for sysplex signaling. The wizard uses the default CLASSLEN value of 956.
-
IXCPATH2 for sysplex signaling. The wizard uses the CLASSLEN value of 16364.
-
ISGLOCK for GRS star.
The Resource Sharing for the Parallel Sysplex creates the following structures:
- WLM structure for Intelligent Resource Director. The plug-in creates a structure with a size of 10240 kilobytes. The name of the structure starts with SYSZWLM_.
- Enhanced catalog sharing. The plug-in creates a structure with a size that is based on the number of active catalogs. The name of the structure is SYSIGGCAS_ECS.
- OPERLOG. The plug-in creates a structure that is based on the total number of writes per second to syslog and how long the records are kept in the coupling facility. The name of the structure is SYSPLEX_OPERLOG.
- LOGREC. The plug-in creates a structure that is based on the total number of writes per second to syslog and how long the records are kept in the coupling facility. The name of the structure is SYSPLEX_LOGREC.
To avoid a single point of failure, you should have at least two coupling
facilities in your configuration.
