At one point in my program, I performing calculations on number of rows(~600,000). I use JSP & JAVA. Here are some things I noticed.
1. It's very slow! :-)
2. Initially, the cpu monitor shows a high level of cpu utilisation, but this slowly drops off with a blip every second or so. Basically, things slow down as the process chugs along.
3. I eventually get a java.Lang.OutOfMemory exception after approx 1:00 -1:30 hrs.
I tried running the JVM with heap size set to 256 Mbytes. I still get the outof mem error.
Is there a faster/better way? Any ideas on how I can get rid of the out of mem errors.....???
I tried searching in the forum for similar kind of discussions but..could n't get the solution for it..Pls help...!!!
