Hi everyone,
I'm about midway through an advanced DataStage class with existBI and we recently went over job optimization in the lab.

I have a good number of jobs that are essentially just moving data with some basic type conversions from one table to another in the same database. Based on what I have learned from the optimize features there's a good chance I could offload a good portion of that to the SQL server itself, in my case a Netezza.

However, my coworker nor I can use Optimize in our Designer. The icon is missing entirely from the toolbar, and it's greyed out under the File menu. Does anyone have any insight as to why this might be?

It's a paid option...

With such "basic transformation" you could optimize it yourself. Few years back that option wasn't there in datastage at all.

Yea, pretty sure we paid for it but I will have to double check. I will have to check into the self optimization further, netezza uses some SQL functions that I am not familiar with and omits some that I am more familiar with. I was quite curious to see how DataStage wrote the code for some of the optimizations from a reverse engineering standpoint. :-p

Thanks QT_KY,
We are indeed 11.5 here, it sounds like this is something that our server administrators may not have setup when they installed InfoSphere?

That is entirely possible. We did not install that option either. At the time of our install, it was not known to us to be a no extra cost option in 11.5.

This can be verified on the server. Go to the install directory where the Version.xml file is:

$ grep -i bal response.txt
DataStage.BalOp=false

Though it is no longer chargeable, it is definitely still an optional installation step. Many administrators don't realize that it was included in the base license at 11.5, and still don't install it.

Be aware that there are a number of restrictions placed on when Balanced Optimization will automatically push SQL down to the database.

Yea it turns out we started with 11.3 and upgraded to 11.5. The individual who did the upgrade was not aware that this was now a non-charged inclusion and just used the same response file he used before. Working to have him get it installed. Thanks for that list of limitations! Looks like most of what I am looking to do is supported so I'm still quite curious to give it a shot on some of my jobs.

Post initial installation, Balanced optimization can be turned on/offthru iisAdmin.

Command to switch it ON:

If it's installed.
