Q Replication
For low latency, DB2-to-DB2 data movement, WebSphere Information Integrator
Replication for z/OS provides another option. This architecture uses WebSphere
MQ Series as the transport for the data, and employs parallel apply agent
technology to deliver low latency data movement. Stored procedure targets and
event publishing offer new options for information integration. The event
publishing capability, which can be purchased separately, formats XML
documents from the captured data and publishes this information via WebSphere
MQ Series. This can drive intra- or inter-business integration.

Scenarios, SG24-6487.
4.2.7 Summary
In today’s complicated, multifacited environments, DB2 UDB for z/OS is a
cornerstone. DB2 provides deep synergy with the zSeries platform and z/OS.
This delivers a data serving platform that is adaptable to change and provides
the highest levels of availability.
While it is important to deliver quick-recovery capability, DB2 for z/OS and the
z/OS platform are designed to go beyond this and deliver continuous availability.
This difference in philosophy places DB2 and the z/OS platform at a higher level
of capability. As explained in this chapter, deployment choices of data sharing,
online utilities, and autonomic definitions allow DB2 to deliver higher availability
while allowing you to make required system and application changes.
The improvement of existing features, and the delivery of new capabilities,
continue to provide superior results on a long history of business resiliency. This
delivers support for both legacy and new workloads, optimized data serving to
the enterprise, and reduced administrative costs.
