Weblogic Cause: org. hibernate. exception. GenericJDBCException: Connection closed, connectionclosed

The weblogic site reports an error, resulting in data delivery failure. The error message is as follows:

### Error opening session. Cause: org. hibernate. exception. GenericJDBCException: Connection closed
### Cause: org. hibernate. exception. GenericJDBCException: Connection closed
Com. gg. corm. exceptions. PersistenceException:
### Error opening session. Cause: org. hibernate. exception. GenericJDBCException: Connection closed
### Cause: org. hibernate. exception. GenericJDBCException: Connection closed

The connection is closed. I think there are two problems: one is that weblogic sets the inactivity timeout time, and the other is caused by the timeout settings in the Oracle database sqlnet. ora.

I have previously written java. SQL. SQLRecoverableException: IO error: Socket closed. The idle timeout value is set to 300 in the data source> connection pool> advanced. If this error is reported, you must set it to a large value, if no error is reported, it is best to optimize the function.
