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.
Hello, see on Youtube our Tivoli System Automation for Multiplatforms high availability solution for SAP. You can find two videos. Part 1: http://www.youtube.com/watch?v=4k22CYXM-f4 Part 2: http://www.youtube.com/watch?v=TGwqQnIGv9E Enjoy ! p.s.: These are both posted to the Tivoli Demos YouTube channel http://www.youtube.com/user/tivolidemos?feature=mhee
Die GSE Herbst-Tagung steht vor der Tür, zum
ersten Mal durchgeführt durch die beiden neuen GSE-Gruppen “Automation and Business Resiliency on Open Systems” und “Automation and Business Resiliency on
Mainframe” . Wann: 25.10.2011 - 28.10.2011 Wo: Köln Wir haben bisher Präsentationen in den
folgenden Bereichen geplant:
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. This
paper describes an approach to creating a highly available SAP solution
that covers all critial components. The IBM High Availability (HA)
middleware solution (Tivoli System Automation for Multiplatforms) provides this level of high availability. High
availability is a term used to describe systems that are continuously
available that are up and running, performing... [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]
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... [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
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!
Get SAMP version
Get RSCT version
Check operator commands
Check operator commands on every node in the cluster
for NODE in `lsrpnode -x | cut -f1 -d' '` ; do ssh $NODE cat /var/ct/IBM.RecoveryRM.log; done
This self-paced audio-visual course provides an overview of the System Automation for z/OS 3.4 functional differences as they relate to implementation and administration. This is is the first of three courses in a set of courses that cover implementation and administration differences. The other two courses provide demonstrations and additional details on specific topics. The functional differences associated with operational commands are covered in a separate set of courses.

With the 220.127.116.11 release of System Automation Application Manager, the capability to manage virtual guests on zEnterprise hardware has been introduced. This allows the SA Application Manager to start and stop virtual servers hosted inside the zEnterprise Ensemble. As this functionality is not only available via the graphical interfaces but also for the command line, our team developed some sample scripts, written in PERL, to show several possibilities of eezcs scripting. You can also browse our manuals for detailed description of the new... [More]
Today we added a new utility to the SA Application Manager WIKI which allows to model tasks as SA resources. This utility can be used together with the Agentless Adapter of the SA Application Manager as well as for the instrumentation of resources in SA for Multiplatforms. What are task resources?
With System Automation it is possible to
manage the availability of all resources in a datacenter. System Automation
ensures the availability 24x7 by constantly monitoring the availability of defined
resources and automatically reacts on... [More]
Tivoli System Automation Application Manager 3.2.2 has released its first pre-canned End-to-end policy. This policy is called "End-to-end Disaster Recovery with DB2 HADR" and is available on the ISM Connect library: http://www-304.ibm.com/software/brandcatalog/ismlibrary/details?catalog.label=1TW10SA08# It is a disaster recovery (DR) solution with System Automation Application Manager as single point of control for operating and disaster recovery actions. Application data is replicated software-based with IBM DB2 high availability... [More]
