Hanging on SQL Queries
Every now and again (1 in 3 times) Rapidminer will hang on an SQL query. Usually my process will take 5 minutes.
By hang I mean the timer just keeps going, for hours, it never resolves.
The data in the database is static, im not updating/writing new rows to it.
is this a common issue? Should I think about doing a large extract from the database to my local machine and working with that?
I sometimes get this: Feb 4, 2012 6:12:29 PM WARNING: Caught exception in concurrent execution of Read Database (Read Database): com.rapidminer.operator.UserError: Database error occurred: Operation not allowed after ResultSet closed
