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: https://www.ibm.com/developerworks/community/blogs/d6a38b59-943a-434b-a473-b408ed64847d/entry/what_is_quorum There are a number of scenarios where clients have ended up with a surviving node unable to obtain quorum during...

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 it? ... [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 IBM.ResourceGroup:App-rg Request=Move Control=MemberInProblemState Nominal=... [More]

in case you haven't seen this so far...... With the introduction of Tivoli System Automation Application Manager (SA Application Manager) version 220.127.116.11 (available since Q4 2011) the SA Application Manager has been enhanced to automate (start/stop) resources that are monitored by IBM Tivoli Monitoring (ITM).This new capability allows ITM customers to not only monitor SW components, but also control and automate SW components which are so far monitored by ITM. A simple example is a multi-tierd online banking application with software... [More]

In How Tivoli Provisioning Manager integrated usability testing in Agile - Part 1 we talked about 3 points on how usability testing fits into the development cycle. In part 2, I will be sharing some other points to make this activity successful. 4. We tested “anything” By testing items that were not complete, we received excellent feedback about the end-to-end customer scenarios and important features that were needed. For example, we tested various designs to validate the general flow of a task from the business perspective. The feedback... [More]
The Tivoli Provisioning Manager development team has implemented usability testing in the Agile development process. By allowing customers to experience the product while in development, we are building a strong partnership with our customers to shape the solution that they need. Here are the main points that we followed to be able to fit formal usability testing into the Agile schedule. By doing so, our team greatly improved the task flow and user interaction for the features tested. 1. We created a team Our usability team is... [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 ... in a nutshell, a group of nodes is... [More]
"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 If critical resources are...

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]

This video also impressively shows the integration of SA and ITM widgets in one combined dashboard. Have a look: http://youtu.be/_5OHhZ0czdU cheers, Josi.
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 trace files are... [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 the log and... [More]
