Recently when i tried to start the WLS sever after fresh installation, i have got the following error:
[WARN ][osal ] could not enumerate processors (1) error=-1073738824
[WARN ][osal ] Failed to init system load counters
The domain has both SOA and OSB managed servers in a machine where the OS is Windows 2003 server.
JRockit JVM is used while creating the domain.
After a little research found out that it’s one of the known issues when using the JRockit JVM on windows.
The following link gives the workaround for this problem.

In my case, i just switched on to Sun JVM by modifying setDomainEnv.cmd file.

Hello,
sorry for my English.
Please, what were your changes to the setDomainEnv.cmd file.
Thanks, regards.
