My apology if you get a duplicated email.

We found out  ""Could not get JDBC Connection; nested exception is
java.sql.SQLRecoverableException:
IO Error: Got minus one from a read call" happened very frequently, almost
every uPortal.log.

Any inputs will be appreciated.

Thanks,
Xin

Hi,

We have uPortal 4.0.10 setup with Oracle Database 11g Enterprise Edition
Release 11.2.0.3.0 - 64bit Production on Exadata, use Oracle JDBC driver
 11.2.0.3.0 (11.2).

During our load test, we found out "Could not get JDBC Connection; nested
exception is java.sql.SQLRecoverableException: IO Error: Got minus one from
a read call" happened sometime on some tomcat instances.

Anyone have been experience this? Would this error have any impact to
your environment? Any idea why this happened? How can we fix it?

Highly appreciate your help.

Thanks,
Xin
