my java code is like:
logger.info("start");
getJdbcTemplate().execute("call " + procedureName + "()");
and I got the exception:
org.springframework.dao.DataAccessResourceFailureException: StatementCallback; SQL [call PRMI_UPDATE_USER_LOGIN_INFO()]; Io ERROR: Connection reset; nested exception is java.sql.SQLException: Io ERROR: Connection reset

at org.springframework.jdbc.core.JdbcTemplate.execute(JdbcTemplate.java:407)
at org.springframework.jdbc.core.JdbcTemplate.execute(JdbcTemplate.java:428)
Maybe it's caused by the long time waiting. I found that it printed " start " in log and after about 5 minutes I got the exception.
update at 2013-03-13:
I got that exception not only at calling oracle stored procedure but at druid's 'JdbcUtil.close(...)':
com.alibaba.druid.util.JdbcUtils.close:81 - close connection error

The druid's JdbcUtil.close method is quite simple:
public static void close(Connection x) {
if (x == null) {
return;
}
try {
x.close();
} catch (Exception e) {
LOG.debug("close connection error", e);
}
}
the source code is : https://github.com/alibaba/druid/blob/master/src/main/java/com/alibaba/druid/util/JdbcUtils.java
It should wait as long as it is needed. Forget about various hacks which try to "detect" deadlock based on timeout delay.
Io ERROR: Connection reset
does not look like Oracle error message, there should be some error number attached to it CPU_PER_CALL
but in such a case you should get an error: ORA-02393: exceeded call limit on CPU usage
. And you connection should NOT be lost Maybe it's caused by the long time waiting
No it is not caused due to that
As Java Doc says about DataAccessResourceFailureException
Data access exception thrown when a resource fails completely: for example, if we can't connect to a database using JDBC.
