Managing the Db2 Mirror environment

After Db2® Mirror is configured and running, changes may be required as your applications and environment evolve.

PTFs for Db2 Mirror
The best practice for Db2 Mirror maintenance is to stay current on some important PTF groups.
Managing the Replication Criteria List
The Replication Criteria List (RCL) contains the rules that determine whether an object is replicated by Db2 Mirror. The system administration team must design a replication strategy prior to implementation, since the initial rules are set during configuration of Db2 Mirror.
Managing the Object Tracking List
The Object Tracking List (OTL) provides the interface for tracking replicated object changes. It contains information and status for objects that have been resynchronized, are being resynchronized, and still need to be resynchronized. There is one tracking table for SYSBAS and one for each database IASP.
Db2 Mirror properties
There are properties within Db2 Mirror which will affect characteristics of the replication environment.
Object replication controls
Object replication controls provide the capability to control object replication for certain replication-eligible object types at the product level.
Managing IASPs
On IBM® i, independent auxiliary storage pools (IASPs) can be used to store data on separate physical disk from SYSBAS. The IASPs can be brought offline separate from SYSBAS and can be replicated or switched between systems using PowerHA® hardware replication.
Managing NRGs
Network Redundancy Groups (NRGs) hide the complexity associated with automated physical network redundancy, failover, and load balancing of connections between the two nodes. When a connection is initiated by Db2 Mirror to perform an action on the other node, an NRG name is specified which logically separates Db2 Mirror traffic by function. Initially, all five Db2 Mirror NRGs are created identically. NRGs may require tuning when configuration changes or for performance reasons.
Managing takeover IP address groups
Many IBM i applications are accessed by using an IP address or a group of IP addresses.
Managing the Submitted Job Tracker
The Submitted Job Tracker is an IBM i work management feature that tracks the lifecycle of submitted jobs for a user specified set of job queues.
