Last updated on MARCH 11, 2022

Applies to:

JDBC - Version and later
Information in this document applies to any platform.


On : version, Thin JDBC driver

UCP cannot create the connection pool using a wallet for authentication.

Tests done:
1) Code does work with Oracle Database using the ojdbc6.jar and ucp.jar from 11.2
2) Specifying user and password directly would work, but isn't acceptable. (not using Wallets)
3) Connecting directly with wallet, but without UCP also works (just to prove that wallet setup is ok)
4) Not able to make it work using JDBC and UCP

Project Constraint: Has to work with Java 7
