JDBC Adapter issue

I am getting the following exception once in a while, can some one let me know what this exception means and I have set Minimum Pool Size: 0. I really appreciate any reply in this regard.

Nancy,

Is this issue with Oracle? If so you might want to check this link

I think you will have to set this in other properties field of the JDBC connection.
