Synchronizing phase

Edit online

When Migrate While Active is in the Data Synchronization stage and the migration phase is Synchronizing, changes to objects on the source node are tracked and asynchronously migrated to the copy node.

Migrate While Active is focused solely on objects within SYSBAS.

Migrate While Active separates the migration processing into three groups:
  1. Db2® Mirror replication-eligible object types.

    The RESYNC_STATUS view returns information from the object tracking list (OTL).

  2. Non-Db2 Mirror replication-eligible object types, that reside within libraries.

    The LIBRARY_MIGRATION_LIST view returns a list of all eligible library-based objects that require migration to the copy node using Migrate While Active.

  3. Objects within the integrated file system, except for objects in /QSYS.LIB and /QDLS.

    The IFS_MIGRATION_LIST view returns a list of the integrated file system objects that require migration to the copy node using Migrate While Active.

While in the Synchronizing phase, you should not attempt to initiate object changes on the copy node. Migrate While Active is actively synchronizing changes from the source to the copy node, and the copy node is not ready at this point to be used. Db2 Mirror replication-eligible objects will prevent any attempt to initiate an object change on the copy node. Non-Db2 Mirror replication-eligible object types and objects within the integrated file system have no blocking protection in place on the copy node.

Note: Do not make changes to objects on the copy node before the Migration Manager has completed Final Synchronization.

When changed objects are successfully migrated to the copy node, those objects no longer appear on the tracking list where they were tracked.

Migrate While Active includes the ability to review historical detail for migrated objects:
  • The MIGRATED_IFS view returns a list of the integrated file system objects that have been successfully migrated to the copy node by Migrate While Active.
  • The MIGRATED_LIBRARY view returns a list of library-based objects that have been successfully migrated to the copy node by Migrate While Active.
