I have a weblogic 6.1 app server running with 1GB RAM on a windows server. Currently I have been using this option: -ms128m -mx512m. What is the optimum heap size to set?

Here is no formula to calculate the optimal size without first hand information. However you can set both the -Xms and -Xmx to same size ie 512MB (BEA recommends this as the memory is allocated in single shot). You may have to enable GC log and analyze how frequently Full GC happens. This way you can find out if you need to increase the size of heap or not.
 
I agree. Here's the link: http://aspose.com/file-tools
