Hi Experts,
I have a small question regarding Information Analyzer 8.1.
Is it possible to run IA jobs(column analysis, primary key analysis, foreign key analysis etc...) across multiple engines.?
For example, I have the below setup.
(1) Client tier : Computer A
(2) Services tier along with colocated engine tier: Computer B
(3) Separate Engine tier : Computer C
Is it possible to run IA jobs across Computer B and Computer C to take advantage of aditional engine capabilities which is on Coputer C in this case.?
OR
IA job can be executed through one engine at a time only.?
Please share your thoughts on this.

IA jobs run as parallel jobs. Therefore the answer is "yes". Even better, apart from providing a valid configuration file, you don't have to do anything to take advantage of this functionality.

Thanks for your quick response Ray. Do I need to register the aditional node by using Information Analyzer --> Configuration --> Analysis Settings --> Validate engine connection options for all the nodes and then update default.apt configuration file with all nodes.
Actually I tried to do this and while validating separate engine connection, i got the below error.
Analysis Connector:Error
Invalid settings:
Error executing DS jon:

No, simply mention a second node in the DataStage configuration file (e.g. default.apt) on the analysis engine. Validate the analysis engine - the one on which the ANALYZERPROJECT project exists. You do have to do all the deployment things that parallel engine requires - sharing the parallel engine software and enabling rsh/ssh between the nodes.

Thanks Ray. I have one more question. Should I NFS mount the Projects directory from conductor node onto computational node such that the Projects(ANALYZERPROJECT and other Projects...) are visible through all the engines.?
If I don't do this, I get error message saying file or directory(/opt/IBM/InformationServer/Server/Projects/ANALYZERPROJECT) does not exist on computaional node.
Please share your inputs on this.
