Our main i2b2 is still currently based in KC on Oracle. We have a local one on sql server, but we haven’t started using it as our production i2b2. So it hasn’t been tested to identify the issue you are speaking of.

Hi, We are starting to run queries against our MS-SQL based i2b2 in Nebraska. We are seeing what seems to be blocking of queries that are trying to be executed in parallel by different users. Does the access to the Fact table by 'active query #1' cause 'active query #2' which also needs to access the Fact table to block? Just wondered if any GPC sites using SQL-Server for i2b2 had run into this, and what they may have done about it.
