IBM i operating system makes use of registered version information entries to enable enhancements to Db2 Mirror for i that require coordination of specific features or functions across both nodes. A version information entry that contains MRDB for its version group and RESUME-INTERNAL-MAINTENANCE for its version name is used to enable features related to resuming replication.
Use the following SQL to display the highest registered version value that is available on both nodes for the RESUME-INTERNAL-MAINTENANCE version information entry:
SELECT ACTIVE_VERSION, ENTRY_SOURCE,
VERSION_GROUP, VERSION_NAME,
PRIMARY_VERSION, SECONDARY_VERSION
FROM QSYS2.MIRROR_VERSION_LIST
WHERE STATE = 'ACTIVE' AND
VERSION_GROUP = 'MRDB' AND
VERSION_NAME = 'RESUME-INTERNAL-MAINTENANCE';
For complete details on viewing registered version information entries stored in the Mirror Version List (MVL), view the IBM Documentation page: MIRROR_VERSION_LIST view.
NOTE: A PTF of Base indicates that the version for the enhancement is enabled in the base release. Base Enhanced indicates that the version for the enhancement was enabled in the base release without any additional PTFs.
