I tested the mifos 2.1.0 on my windows vista machine with Tomcat 7.0 and it worked fine. But When I tried to install and run the same with the above configuration it did not get deployed. I tried with Tomcat7.exe command option it ran. Now every now and then it shows java Perm Gen Space Error. I tried to increase memory in CATLINA_OPTS to 2048 but still the problem persists.

This is a common problem with any large Java application when JVM arguments are not setup as required.
You can try increasing then memory and if it doesn't work provide then more information and reopen the issue.
Information like what is the size of your database or possibly share the JVM dump on OOME
