I am a newbie and I encountered with the following error when trying to connect to the database. I searched the forums and tried all kinds of solutions that might resolve the issue but didnt work out. Could someone tell me what could be the cause for this error.
[ART.118.5042] Adapter Runtime (Connection): Unable to enable connection resource ABC_Env.Adapters.DB:Log_Conn.
[ART.118.5036] Adapter Runtime (Connection): Unable to configure connection manager.
[ADA.1.204] Cannot connect to the database with DataSource class “oracle.jdbc.pool.OracleDataSource”.
Io exception: Connection refused(DESCRIPTION=(TMP=)(VSNNUM=168821504)(ERR=12505)(ERROR_STACK=(ERROR=(CODE=12505)(EMFI=4))))
I appreciate your input.
