[ADA.1.204] Cannot connect to the database with DataSource class "oracle.jdbc.pool.OracleDataSource".
Io exception: Got minus one from a read call

suggest to check the db availability

Ping and telenet to the destination ip adresss seems issue with the app.or db to which you are connecting to, if unable to ping or telnet ask the respective app or db team to check their system.connectivity

Basic error for a normal webMethods developer. .. once we keep on practice, we can rectify like this errors..... .... This error may be chance of DB down, or jar file missing, or table space not created while running DB configurator, or grant permissions to the respective schema in the oracle DB ....

Issue can be with DB.. check whether you are able to connect that DB with any oracle client or sqldevelper..

If you are able to connect from through oracle client then check the correct jar file and associated DataSource Class in connection parameter i.e sqlserrver:- com.microsoft.jdbcx.sqlserver.SQLServerDataSource Oracle:- oracle.jdbc.pool.OracleDataSource

can you place 'ojdbc6.jar' file in webMethods Installation Dir->Integration Server->lib->jars folder and restart IS.........your problem gets resolved

Lot of answers related to DB connectivity which is exactly the issue, however to be more specific, the reason is - "Oracle DB, reached the maximum connections limit. You may wait for some time and try again later or work with Oracle DBAs to kill the inactive connections".
