First of all, confirm which target the TX map is failing to connect to, by using the audit log.
If it is indeed the Oracle database, then check that the MDQ is available in the directory that the map code expects it to be in. Then check that the Oracle connect string has been defined in the server .ora file. Make sure that you have an Oracle client install on the server and that the TX user is authorised to connect to the database. It may prove helpful setting a DB trace on the TX map where the DB call is initiated.
If it isn't one of those, then perhaps there is a network issue (firewall for example) that is preventing the map from connecting to the database.
Good luck -
