Our server had a unexpected shutdown and now the Method Server refuses to start.

Error log from Method Server:

Any help would be immensely appreciated!

The error means could not find the class under classpath. The class is for Options Variants.

 

1. Use which command to check whether it exits or not, please recover if it was gone.

java wt.util.jmx.Which com/ptc/windchill/enterprise/generic/server/GenericService.class 

-it should under <windchill>/codebase

 

2. Verify the classpath

- Look MS log, it will display all ClassPaths of Windchill whether <windchill>/codebase is the first

I was able to manually find the GenericService.class file under <windchill>\codebase\wt\generic 

And the MS log shows a classpath including <windchill>/codebase, but not <windchill>\codebase\wt\generic specifically.
Here's the full classpath from the log file:
