This chapter contains information about support provided by MIMIX commands for synchronizing data between two systems. The data that MIMIX replicates must by synchronized on several occasions.

  • During initial configuration of a data group, you need to ensure that the data to be replicated is synchronized between both systems defined in a data group.

  • If you change the configuration of a data group to add new data group entries, the objects must be synchronized.

  • You may also need to synchronize a file or object if an error occurs that causes the two systems to become not synchronized.

  • Automatic recovery features also use synchronize commands to recover differences detected during replication and audits. If automatic recovery policies are disabled, you may need to use synchronize commands to correct a file or object in error or to correct differences detected by audits or compare commands.

The synchronize commands provided with MIMIX can be loosely grouped by common characteristics and the level of function they provide. Topic Considerations for synchronizing using MIMIX com-mands describes subjects that apply to more than one group of commands, such as the maximum size of an object that can be synchronized, how large objects are handled, and how user profiles are addressed.

Initial synchronization: Initial synchronization can be performed manually with a variety of MIMIX and IBM commands. For information about initial synchronization, see these topics:

  • Performing the initial synchronization describes how to establish a synchronization point and identifies other key information.

  • Environments using MIMIX support for IBM MQ for IBM i have additional requirements for the initial synchronization of replicated queue managers. For more information, see the Assure MIMIX for IBM MQbook.

Synchronize commands: The commands Synchronize Object (SYNCOBJ), Synchronize IFS Object (SYNCIFS), and Synchronize DLO (SYNCDLO) provide robust support in MIMIX environments, for synchronizing library-based objects, IFS objects, and DLOs, as well as their associated object authorities. Each command has considerable flexibility for selecting objects associated with or independent of a data group. Additionally, these commands are often called by other functions and by options to synchronize objects identified in tracking entries used for journaling. For additional information, see:

Synchronize Data Group Activity Entry: The Synchronize DG Activity Entry (SYNCDGACTE) command provides the ability to synchronize library-based objects, IFS objects, and DLOs that are associated with data group activity entries which have specific status values. The contents of the object and its attributes and authorities are synchronized. For additional information, see About synchronizing data group activity entries (SYNC-DGACTE).

Synchronize Data Group File Entry: The Synchronize DG File Entry (SYNCDGFE) command provides the means to synchronize database files associated with a data group by data group file entries. Additional options provide the means to address triggers, referential constraints, logical files, and related files. For more information about this command, see About synchronizing file entries (SYNCDGFE command).

Procedures: The procedures in this chapter are for commands that are accessible from the MIMIX Compare, Verify, and Synchronize menu. Typically, when you need to synchronize individual items in your configuration, the best approach is to use the options provided on the displays where they are appropriate to use. The options call the appropriate command and, in many cases, pre-select some of the fields. The following procedures are included:
