Which release? In 10.1 it is in <Windchill>/codebase/wvs.properties. In 10.2 it is in <Windchill>/codebase/WEB-INF/conf/wvs.properties.
Use xconfmanager to set it. For example
start a windchill shell
xconfmanager -p -t codebase/wvs.properties -s <somekey>=<somevalue>
xconfmanager -p -t codebase/WEB-INF/conf/wvs.properties -s <somekey>=<somevalue>
It should be the second command. Did you copy/paste? If so, try typing manually because the dash often does not copy/paste correctly.
Can you run "xconfmanager -p" to propagate?
Can you run "xconfmanager -p -t codebase/WEB-INF/conf/wvs.properties -s testkey=testvalue?
Does it give errors or does it write "testkey=testvalue" into the file?
I suppose that you have access to the windchill server.
Go to the file <Windchill root folder>/Windchill/site.xconf
This is the master file for changes, inside of it you can find commands as:
<Property name="NAME OF THE PROPERTY" overridable="true" targetFile="codebase/WEB-INF/conf/wvs.properties" value="VALUE FOR THE PROPERTY"
And there is your wvs.properties, in the path <Windchill root folder>/Windchill/codebase/WEB-INF/conf/wvs.properties
After that, all the chagest must be realized in the site.xconf ussing that style. You can't change wvs.properties directly.
When you finish to change/add/delete etc all the properties in site.xconf, you must go to windchill shell and write:
This is the step by step method for changes, for your security.
severals of the changes need that you reboot Windchill, other only the background.

I always put properties files into a spreadsheet to record the OTB values.
Best practice is to add a few columns - OTB value, your current value, comments.
