http://serverfault.com – I have a websphere application which runs under the user wsadmin. The application invokes the SQL bulk loader client ./sqlldr The sqlldr needs some environment variables predefined in order to work such as ORACLE_BASE=/usr/app/oracle ORACLE_HOME=/usr/app/oracle/product/11.2.0.1/client_64 ORACLE_SID=VDO1018 Can you tell me what is the best place to put these variables.
