Currently using File-AID across our org. We're mostly using it for creating test data and compares.
Pros
Extract/load data from one DB or table to another masking the data for testing.
Compare extracts against each other to ensure good baselines.
Cons
I find it more obtuse to use than IBM Optim.
Related tables are difficult to incorporate.
Likelihood to Recommend
It's pretty good at creating an extract of a whole table, but not the best at grabbing all related tables in my experience. Pretty intuitive on setting up your test data categories. I also really like that it can either run via ISPF or via Topaz which was included with our purchase.
