Error in JDBC Connection

I connected thru JDBC to the one database and when I am trying to connecting to other database but it is giving the following error I connected to the Siebel adapter also as part of project

Error encountered

[ART.118.5042] Adapter Runtime (Connection): Unable to enable connection resource GE_CMS_JDBC_Adapter.Connections:CMS_JDBC_Connection_01.
[ART.118.5036] Adapter Runtime (Connection): Unable to configure connection manager.

Thanks in advance,
