Oracle Database Extension - "No keepalive from datasource" error

Starhut

Hi guys, I am testing on the Oracle Database extension. 

After added the Oracle endpoint and established the connection, an error "No keepalive from datasource sqlOracle. Restarting" kept showing and the metric collected in incomplete.

Any configuration can be done on Dynatrace to solve it?

Hi

I did the integration before and no additional configuration is needed.

Please revert to the Database team to inderstand and try to find something.

My team encountered an identical problem on our client env.

We have an open ticket. If I know more, I will let you know 🙂

Have a nice day!

To update on what we have done: 

1. check on parameter SQLNET.EXPIRE_TIME 

2. remove and configure the extension again.

3. update the extension to latest version 

4. Research on keepalive setting in DB server and found that it is always on automatically in server by default. 

After all the changes above, error still there. Now, we are looking for a new direction on troubleshooting this issue.

I had this problem in another v2 extension, in this case SNMP.

I did all type of tests, but then seeing this thread, I decided that would delete and recreate the monitoring configuration. To do that I preserved the JSON configuration.

To my great surprise, when I was recreating the monitoring configuration, I detected an IP with a trailing space. It worked after I recreated, but I would check if there's a space somewhere, in case someone gets this error too.

Same as @AntonioSousa in my side ! The space in the IP field (POST via JSON payload) broke the entire Extension engine on the AG ... Like a loop in the process, high memory and cpu. Tricky debug to find it.
