Exasol connectivity issues on Tableau Server

sikumar

Hi all,
 
We have recently migrated from Exasol on-prem to AWS(Exasol 7.0.16).
Post-migration, we are able to connect from Exasol Server to Tableau Desktop.
We have tried using various ODBC Drivers (6.1.0, 6.2.5 ,7.0.0 , 7.1.0) to test.
 
But we are facing issues connecting to Exasol Server from the Tableau Server.
We see that connectivity gets established intermittently and fails most of the time.
When we checked the Tableau Server logs, this is what we could find:
 
Tableau Server logs(When Connection fails): Communication with the Tableau client process was lost. Tableau client process might be terminated, possibly due to system resource constraints or another external source
 
Tableau Server logs(Just before the Connection succeeds occasionally):
SRM-ReleaseFreeFromHeap: Successfully released free memory from heap"}
 
Has anyone faced this issue before?
 
Any suggestions will be greatly appreciated.

@exa-Nico - Thanks for the reply!

Yes this was due to a routing issue on AWS instance and we got it resolved once the AWS exasol data node IPs were allowed to connect to the Tableau server.

Hi @sikumar based on the error message, it seems like it's a Tableau error. The error messages are not an Exasol error message at least, so I'm not sure if it even was able to connect to the Exasol database anymore. Has Tableau support said anything about it?
