Starting with version 1.4, dbRadar uses the Oracle instant client. Therefore there is no need to have the Oracle client libraries installed as a prerequisite for making a connection.
All you have do is set the ORACLE_HOME or TNS_ADMIN environment variables so that dbRAdar can find the tnsnames.ora file.
export TNS_NAME=_path_to_your_tnsnames_file
Use the following tnsnames.ora file to make your settings:
MARI.WORLD =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = server)(PORT = 1521))
)
(CONNECT_DATA =
(SID = mari)
)
)
