IBM Data and AI Ideas Portal for Customers


This portal is to open public enhancement requests against products and services offered by the IBM Data & AI organization. To view all of your ideas submitted to IBM, create and manage groups of Ideas, or create an idea explicitly set to be either visible by all (public) or visible only to you and IBM (private), use the IBM Unified Ideas Portal (https://ideas.ibm.com).

Avoid Single point of failure for Db2's critical files

If the critical files of Db2 damage, e.g. by erroneously deletion, file system corruption Db2 will no longer be available (#usable). Since some of the critical files are permanently updated a restore of the critical files does solve the problem. A loss of (part of) the local database directory requires a complete restore of a database which means hours of outage.

Mirroring the local database directory to a different path (preferably a different file system) could make Db2 tolerant to such kind of problems. This kind of enhancement could work roughly comparable to MIRRORLOGPATH, which allows to configure a mirror path for the log files, a DB parameter like DBDIRMIRRORPATH could allow to specify a mirror path for the local database directory

    Improved resilience through control file mirroring

    The Db2 database engine stores internal state and control information within internal control files in the database path. The information in these control files is required for operation. Starting in 11.5.7, it is possible to specify a redundancy path where a copy of these files is maintained, which may aid recovery in the event that the control files are inadvertently deleted, corrupted, or no longer accessible within the database path. For more information, see ctrl_file_recov_path - Database control file recovery path configuration parameter.

SQLOGCTL.LFH.1 contains very important log control file infos, and therefore has a redundant copy named SQLOGCTL.LFH.2 . However, both files always reside in the same directory. An option is needed, to configure a second directory/path, so that bo...
