Given a 2 node domain, what option do you have to allow a single node to obtain Operational Quorum after bringing one node offline and knowing your TieBreaker device will not be accessible from the surviving node ?
Firstly, if you want to know more about "Quorum", check out one of my earlier blogs:
There are a number of scenarios where clients have ended up with a surviving... [More]
Why are you using the Tivoli System Automation for Multiplaforms (TSAMP) product with your DB2 HADR or DB2 HA Shared Disk environment ?
The answer should be to keep the DB2 service highly available (and provide some operational convenience via some basic automation TSAMP can provide).
But how do you know your HA environment is prepared for that unexpected problem. In my mind, its similar to a "backup" you take to help you recover from an unexpected event ... how do you know the backup is good and will restore when you need... [More]
Ever tried to bring a resource offline only for it to result in a state of "Stuck online" ?
A "Stuck online" situation could also prevent a move request (failover) since the first step of a move is to stop/offline all resources that are in the scope of the move.
Your first sign of a "Stuck online" situation will likely be from the output of the 'lssam' command. Here is some sample lssam output :
Stuck online... [More]

To understand how things are organized in a TSAMP/RSCT environment, we start with the idea that almost everything is considered a resource. Of course there are different kinds of resources and that is where we introduce the concept of a resource "class". Then there are different Resource Managers, each responsible for managing or controlling resources that belong to a particular set of resource classes. The following diagram shows the mapping of three key Resource Managers to some Resource Classes they manage and then to some example... [More]
A Network TieBreaker is a popular configuration option for a Tivoli System Automation for Multiplatforms (TSA MP) managed environment.
But what is a TieBreaker and why is it needed ? To understand the what and why, you first need to understand the concept of "quorum" ... please see my blog titled "TSA Blog Series: High Availability Concepts - What is Quorum ?" https://www.ibm.com/developerworks/community/blogs/d6a38b59-943a-434b-a473-b408ed64847d/entry/what_is_quorum?lang=en

"The Majority Rules !"
In a nutshell, you have Quorum if you have the majority.
Quorum is the number of "operational" nodes in a cluster that are required to control the resources, modify the cluster definition, or perform certain cluster operations.
The main goals of quorum operations:
- identify who has the majority when a cluster is broken up into sub-clusters
- keep data consistent, especially when shared file systems are being used
- protect critical resources … maintain HA control

SA AppMan and zEnterprise
ITM monitored resources with SA AppMan
The tool appcmd can be used for testing IBM Tivoli System Automation for Multiplatforms policies as well as IBM Tivoli System Automation Application Manager end-to-end and Agentless Adapter policies. In order
to verify that your policies work as expected, they need to be tested.
In particular, it has to be tested whether resources are recovered as
expected in failure situations. It is very time-consuming to perform
such tests with real applications because all failures to be recovered
need to be injected manually. This application... [More]
The Tivoli System Automation development team just released a whitepaper on SAP High Availability with Tivoli System Automation for Multiplatforms on AIX and Linux.

I'm also including the URL to the official guide
Configuring an IBM Tivoli Storage Manager cluster with IBM Tivoli System Automation for Multiplatforms
that shows how to set up and operate an SA MP cluster to keep TSM highly available.
since it it not easy to find, I'm including the URL to the official TWS integration guide here.
Tivoli Workload Scheduler - Integrating with other products
Chapter 6 of this guide explains how to set up and operate a cluster with SA MP to keep TWS highly available.
there is a new cool video on youtube showing the (old) integration of SA Application Manager with ITM to add policy-based automation on resources of a datacenter being monitored by ITM. This video also impressively shows the integration of SA and ITM widgets in one combined dashboard. Have a look: http://youtu.be/_5OHhZ0czdU
The simple answer is RSCT (the "cluster" software) trace data from key daemons (sub-systems) like IBM.ConfigRM, cthags, cthats, and possibly even RMCd. IBM Support would use this trace data to confirm whether or not it was RSCT that forced the reboot, and if so, then why.
However what isn't always that simple is collecting these trace files before they wrap. The trace files for all the RSCT and TSAMP core daemons and Resource Managers are setup to be a fixed size and First-In, First Out (FIFO). Some of these... [More]
In a previous blog, I talked about the importance for collecting and providing diagnostic data. For the Tivoli System Automation for Multiplatforms (TSA MP) product, this means running its automated data collection utility called "getsadata".
However, there are details about a problem situation that cannot be obtained by a tool, script, or bunch of commands. The most obvious is the problem description itself. So what does a good problem description entail ?
Well a timeline for one. Lets say Support staff have to dig into... [More]
If you're planning on asking IBM Support for help, more than likely there will be a minimum amount of detail they will need up front. The most obvious being details about your environment, such as platform/OS and product versions.
Now if you're needing the root cause for some event that has since pasted, then keep in mind that someone providing "remote" support will likely need historical log or trace data before they will be able to offer you anything significant.
For the Tivoli System Automation for... [More]
We've created a "landing page" for a collection of support resources pertaining to the Tivoli System Automation for Multiplatforms (TSA MP) product. Think of it as the home page for your initial Support needs. Here's the direct URL :
This page is permanently linked off TSAMP's IBM Support Portal site, referred to as "Featured documents".
The landing page is actually divided into a collection of categories, each with their own home page.... [More]
Here are some power-user commands mainly for servicing SA MP which I have gathered over time and are worth sharing. They can be made into shell aliases or just used as is. Have fun!
