Do you meet this error? "Could not load **Master", Reason 500, Could not create a transaction to Thingworx Persistance provider. I open the Application.log and find the detail. How to solve this problem? Many Thanks.
Hi Yijun, seems like connectivity issue to PostgreSQL. Are you able to perform other tasks in Composer e.g. creating/editing a Thing? Does the issue persist despite the Tomcat restart? Can you check and share the tomcat's catalina.log file here? Is ThingWorx and Postgresql running on different machines?
I didn't use the PostgreSQL. There are some properties' values will be deleted when 12:00 p.m. So I call the Timer5s services as a subscription.
The issue will be disappeared if I restarted the Tomcat. I connect the Thingworx with MySQL server. But they are in the same machines.
I check the initial memory pool and maximum memory pool of Apache Tomcat 8.0 Properties (Java). They are none. By the way, I didn't set the Java options.
If I set the java options as the following, I cant start the Tomcat. It will shut down automatic.
So, how to solve this problem?
Thanks a lot.
Hi Yijun, when you restart with those Java options what error message do you get in the Tomcat's catalina log? I think that needs to be fixed since we need those options for Tomcat. BTW, are you defining Xms and Xmx for the tomcat JVM?
Hi Sushant, the catalina error logs are showed above. Today's log has no error.
By the way, I didn't set/ define Xms and Xmx for tomcat JVM.
I just do some setting as the following
Yijun, but these errors are from 5th Sept, are these same even when you add all the JAVA options for the Tomcat?
I am out of office those days. I got the error messages from my colleague. I come back and change some JAVA options today. Just like add/delete :
Delete the Initial memory pool and Maximum memory pool. But when I open the ThingWorx again, IE browser oops, and Chrome tells me that no memory. Just I post in another discussion. (IE browser looks oops)It looks so unreasonable. I don't know what happen. Looking forwards to your reply.
Thank you Yijun, I'll have look at the logs you have shared. Will check and get back to you.
