Thanks Experts.<br />
<br />
We did make some changes on the memory settings that help to resolve this error on few databases. Still working with Oracle support on this.

If you didn't get an answer I suggest you delete the question.<br />
<br />
That is better than accepting answers that didn't help locate a solution, like ping the servers and make sure the database is up...

We're getting intermittent connection issues with the databases. <br />
<br />
The error we're getting is &quot;ORA-12537: TNS: Connection closed&quot;<br />
<br />
This server is running 13 databases with their own oracle homes.<br />
<br />
Where should I start looking to fix this issue?<br />
<br />
Thanks,<br />
