logging no longer works after tomcat upgrade

Hi, we do have a yet another delightful problem with ThingWorx. We have updated Tomcat from 8.0 to 8.5. 

We have changed server config file as instructed and java properties in tomcat config utilities. 

We deployed ThingWorx into the new Tomcat (coppied war file, autodeploy true by default) 

Everything works fine except for the fact that platform is no longer logging anything into the log files. 

No script log, no application log no nothing. 

 

Anyone any help. 

I am very exhausted to debug such a software....

Hi there,

sorry for delayed answer. It was very hectic at the end of the year. 

So..

After some back and forth it turned out that it was indeed a permission issue after all. 

For some reason Tomcat 8 install it self as (rather "under account of") local system, but 8.5 as local service. Difference is that local service has R/W permissions (that is why Import/Export in/from ThingworxStorage/repository worked, as well validation.properties file has been created after startup), but local system has full access permissions. I dont why that is necessary, but it is. 

We changed under which account Tomcat has to run and now everything works. 

It was not obvious because there were no errors in tomcat log files.

Any errors listed in the catalina.log (my guess is that application log is blank)

You've probably already check the permissions on the ThingworxStorage folder and its subfolders?

    Tomcat runs under the same user as previous version of tomcat so I guess that permission is not an issue. 

    Plus - Export, IMport, Repository all works, if permission would be the issue none of that would work as well right? Repository is also under ThingworxStorage. ESAPI file was also created after Tomcat started.

    Hi @tcoufal.

     

    Which version of ThingWorx are you running and which exact version of Tomcat did you upgrade to?  What platform are you running on?  In Composer, do you see logs under Monitoring?

     

    I am happy to open a case on your behalf in order to work with a Support engineer on a solution.

     

    Regards.
