Support for replicating Db2 system-period temporal tables

iCluster 8.2 fully supports replicating IBM Db2® system-period temporal tables and the associated history tables. System-period temporal tables were introduced in Db2 for i in the IBM i V7R3 release.

New group type *HADR for high availability and disaster recovery

For some critical business requirements, replication to a single target is not sufficient. More customers are now replicating to both a High Availability server as well as a remote Disaster Recovery server, increasing switchover complexity and putting more demands on the IT team. To help simplify three-way switching processes, Rocket iCluster v8.2 has introduced *HADR replication group types, we have added a new group type called *HADR for this release. This is a replication group with three nodes–a primary node, an HA backup node and a DR backup node.

Parallel processing for better performance

The following commands and processes can now do their work using parallel processes:

  • *CHECKSUM sync check
  • DMOBJCNT
  • DMAUDITRPT
  • DMRPLCVRPT
  • DMMRKPOS for native objects (DMMRKPOS and DMSETPOS also use parallel processing for BSF. This support was added in iCluster 8.1.)
Additional enhancements
  • Replication support for SQL sequences as an SQL object type
  • Replication of journaling attributes for files (PF-DTA and BSF)
  • Options *MEDIUM and *HIGH for object compression in the DMSETSVAL command
  • Refresh of SQL triggers with CREATE TRIGGER statements longer than 32K bytes
  • Automatic creation of a second remote journal for a local journal if necessary
  • “Change object auditing” parameter added to DMCHGROLE and DMSTRSWO
  • Cascaded MQ Series replication
