Applies to:Universal Connection Pool - Version 18.104.22.168.0 and later
Information in this document applies to any platform.
An application defines a UCP data source that does not contain the user/password.
The connections are retrieved as:
Connection connection = dataSource.getConnection("login", "password");
The initial pool size is 0.
Using UCP 22.214.171.124 this works fine.
Using UCP 126.96.36.199 this fails as UCP is trying to create a connection when the pool is started:
java.sql.SQLException: Unable to start the Universal Connection Pool: oracle.ucp.UniversalConnectionPoolException: Cannot get Connection from Datasource: java.sql.SQLException: ORA-01017: invalid username/password; logon denied
This issue can be demonstrated using the following sample code:
