Once a sysplex has gained ownership of a coupling facility, CFRM
continues its initialization by reconciling the data being maintained
about the current coupling facility environment and, if necessary,
by cleaning up the dump space in the coupling facility.
- Reconciling the data
The system maintains
data about use of coupling facility resources in both the active policy
and in the coupling facility itself. The coupling facility data is
assumed to be more accurate. The system performs the reconciliation
process for each coupling facility for which the sysplex has gained
ownership. The process consists of comparing data about use of the
coupling facility resources from the coupling facility with the data
in the active policy. The reconciliation actions taken by CFRM might
include deallocating structures that are not persistent and have no
persistent connections. CFRM also checks that all persistent structures
are listed in the active policy, and must determine how to handle
structures or connections remaining in the coupling facility but not
in the active policy. The operator might be required to request the
deletion of these structures, or CFRM might reconstruct the active
policy by adding the structures or connections.
- Cleaning up the dump space
If there were
dumps in progress at the time of transition to a new active policy,
the system dumps all captured data to a dump data set.
If the
operator had issued a CHNGDUMP,STRLIST command to initiate one or
more new structure dumps, the dump contains information for each structure
listed on the STRLIST parameter.
