Welcome to the Data Center Automation Blog, where you can read the perspectives from storage management experts. This Blog provides insights into the data center automation solution, as well as technical details about specific IBM products.
I wrote a new tool I call "db2tsacheck" to help avoid unwanted surprises due to configuration problems. Its sole purpose is to look for as many configuration problems as possible for TSAMP managed DB2 HADR or DB2 HA Shared Disk environments. Its a tool you can run on a periodic basis to validate all is well with your configuration.
To download the new version, please visit the following URL:
Although the first two releases provided good coverage of known... [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]
A new paper has been released on the System Automation Application Manager WIKI:
Paper: Integrating OSLC
It contains information and examples (in Java® and PERL) on how to control End-To-End resources via REST calls. For scripting this eliminates the necessity to log on to the node hosting the SA Application Manager and does not need to start a JVM (like eezcs does).
As always we are very interested in your feedback and any nice solutions (like handy scripts) you are developing.

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
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]
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]
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]

This conference addresses the needs of System, Network and Automation Administrators. Sessions are presented by representatives from IBM software development teams and YOU, the product exploiters. Interaction and feedback is both expected and encouraged.
Topics cover a range of IBM system management products, including IBM Tivoli System Automation Family (SA z/OS, SA for... [More]
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]
IBM Education Assistant or "IEA" has released 135 videos and links to You Tube videos so far this year.
What is IEA?
The IBM Education Assistant (IEA) integrates narrated presentations, Teach Me Demonstrations, tutorials, and resource links to help you successfully configure and use IBM software products.
In detail, the information provided in IEA is role and task based to demonstrate how to accomplish "specific" tasks in your software product(s). The term coined for this is aptly named... [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
