Error in getting the tenant status - wso2

Question

I have an instance of Stratos 1.5.1 running. After stratos sits over night without having been interacted with I get the following message on login to Identity Server
And I have added the autoReconnect to true both in the url call and in the property tag of user-mgt.xml
If anybody has an idea why the autoReconnect is not working that would be great. Thanks.

You should consider either expiring and/or testing connection validity before use in your application, increasing the server configured values for client timeouts, or using the Connector/J connection property 'autoReconnect=true' to avoid this problem.

Answer 1

I followed instructions at
http://www.lahiru.org/2010/07/keep-live-connection-in-wso2-products.html
to correct this problem.
What this says to do is keep the mysql connection available. This required that i add these attributes
wait_timeout=259200
interactive_timeout=259200
and values to the /etc/my.conf file. I restarted and then waited 24 hours to verify and tried logging in again and this time it worked.
