Weblogic nodes are taking a long time to start

Tried one node with 2GB and the node failed to start. the second node was shutdown. So, you want me install weblogic server and setup nodes with 2GB. this will not solve my problem because the application requires weblogic portal. whenever the nodes are started the logs are throwing the below errors and the nodes comes up after those errors stop.

We are unable to start the ndoes with 2GB of JVM. Is this because we are running 32bit JDK on 64bit windows 2003 machine? where I can we find the 64bit weblogic portal 10.3.2 installer for windows 2003 64bit STD edition server. we already installed the weblogic portal 10.3.2 with 32 bit JDK, can we just change the JDK from 32bit to 64 bit? if yes then can you please provide us the 64bit JDK installer?

1. Please follow these instructions to make the 3GB flag for windows server 2003. http://technet.microsoft.com/en-us/library/bb124810%28EXCHG.65%29.aspx

2. To change to 64 bit of JDK , its just simple download the 64 bit of installer to your machine and point this 64 bit jdk while creating the domain , in domain creation wizard there is a "configure server start mode and JDK " section . so point the 64 bit jdk here and you are all set.
