UCP version 12.2.0.1 Requires User Name For Pool Start (Doc ID 2267158.1)

Last updated on FEBRUARY 14, 2019

Applies to:

Universal Connection Pool - Version 12.1.0.2.0 and later
Information in this document applies to any platform.

Symptoms

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 12.1.0.2 this works fine.
Using UCP 12.2.0.1 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:
