• Does anyone know of a good guide to configure GC in Java?

  - by evilpenguin

  I'm having trouble with a JVM running an app, whose heap memory looks like a comb. It's constantly jumping from 1.5 GB to 3 GB and slowly deteriorating to higher values. I'm using G1 GC algorithm, but have no idea how to configure it. I do not have access to the code of the app I'm running and, needless to say, it's a rather large app. So, bottom line, does anyone know of a good guide to configure GC in Java?

The type of the generic class cannot be retrieved directly because there is no type for a generic class without a type parameter provided.

• I need to programmatically remove a batch of unique constraints that I don't know the names of.

  - by Bill

  I maintain a product that is installed at multiple locations which as been haphazardly upgraded. Unique constraints were added to a number of tables, but I have no idea what the names are at any particular instance. What I do know is the table/columnname pair that has the unique constraints and I would like to write a script to delete any unique constraint on these column/table combinations. This is MSSQL 2000 and later. Something that works on 2000/2005/2008 would be best!
