oracle.ucp.UniversalConnectionPoolException: Cannot get Connection from Datasource After Changing User Password (Doc ID 2407765.1)

Last updated on AUGUST 30, 2023

Applies to:

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


After changing passwords of the users of a Tomcat application using UCP and JDBC,  a new application war file is created and moved into a java environment. 

When Tomcat starts up, it fails with the error:

java.lang.Exception: Exception in ConnectionPool constructor():
oracle.ucp.UniversalConnectionPoolException: Cannot get Connection from Datasource

The application has a verify_password function that validates the password to be of a certain length. After changing the passwords to the new length required by verify_password function, the connections fail.

Resetting passwords to what they were before being changed works fine.



 Passwords were changed.
