IDS 11.5 Presentation

While surfing the Internet I discovered the following interesting presentation. It covers the business continuity features of IDS 11.5:

IDS 11.5 - MACH Your Business Continuity

More information about IDS 11.5 can be found here:

• DBTA Magazine: Inside Informix V11.5
  

IBM has recently released a new RedBook, called "Informix Dynamic Server 11: Extending Availability and Replication"

It looks to be a comprehensive review, covering:

Preparing the technical infrastructure
High availability data replication
HDR: Advanced use scenarios
Remote Standalone Secondary servers
Shared Disk Secondary servers
Updatable Secondary servers
Connection management in an IDS cluster environment
Enterprise Replication
Instantiating Enterprise Replication
Making changes in Enterprise Replication

Messing around with MACH11

I recently had the pleasure of playing around with MACH11 in a demo environment. In much the same way as onbar is trivial to set up once you have a storage manager going, once you've got all the background hoo-hah of building instances done, it's amazingly simple to build a MACH11 cluster!

You need to tell the primary that it's the primary for each kind of replication you're going to use (with onmode -d commands. In my case it was HDR, SDS and RSS -- going for broke.

• You need to set up some non-shared disk for SDS.

Abstract:

MACH 11 - Setup a SDS Node in 5 Minutes

If you didn't had the time to play with the SDS (Shared Disk Secondary) functionality which is part of the MACH 11 technology introduced in IDS 11, here is a short summary how to setup a SDS node on the same machine. It will take you only about 5 minutes to get the SDS node up and running.

I assume that you already have an IDS 11 instance running on your machine. If not, download the cost-free IDS Developer Edition:

MACH 11 - IBM Whitepaper published

You want to know more about MACH 11 ?

Then download and read the new IBM whitepaper below which talks about this outstanding new Informix clustering technology:

Availability Solutions with IDS 11

I got several requests to translate my german article which is a roundup on the MACH 11 functionality available with IDS Cheetah. So here is a translation of the article:

MACH 11 stands for Multinode Active Cluster for High Availability.

It is an extremly flexible High Availability Technology which is fully integrated in the Informix DBMS Kernel and builds upon the efficient and nearly linear scalable multithreaded architecture.
