SOFTWARE-RECLONE version entry

IBM i operating system makes use of registered version information entries to enable enhancements to IBM Db2 Mirror for i that require coordination of specific features or functions across both nodes. A version information entry that contains DB2-MIRROR for its version group and SOFTWARE-RECLONE for its version name is used to enable features or enhancements related to software reclone.

Software reclone is a type of reclone operation where only the replicated objects are copied from the source of the reclone to the target. Objects, which depend on those replicated objects might be affected on the target node, but other nonreplicated data, the OS, and products on the target are not be affected. A software reclone can be done on SYSBAS or on a database IASP. View the IBM Documentation page for a complete description of Software reclone process.

Use the following SQL to display the highest registered version value that is available on both nodes for the SOFTWARE-RECLONE 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 = 'DB2-MIRROR' AND
          VERSION_NAME  = 'SOFTWARE-RECLONE';

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.

• Active version:  2.1
• Version group:  DB2-MIRROR
• Version name:  SOFTWARE-RECLONE

Version 2.1 enables enhancements in the handling of journal and journal receiver objects during software reclone. Enhancements include reassociating any journal receivers that were disassociated from the replicated journal and reestablishing any remote journals that were removed during the software reclone. For complete details, view the IBM Documentation page: Journaling consideration for software reclone.

The enhancements for this version are enabled after the following IBM Db2 Mirror for i and Db2 for i PTF Groups have been loaded and applied:

• IBM i 7.5 - [Base]
• IBM i 7.4 - [SF99668 Level 19 and SF99704 Level 20]
