While running a mb program to connect to oracle database , we are getting Database Initialization error
ERROR  :20080413:15.27.03:r4edi(oratest):Oracle returned the following error: Oracle returned -1 when trying to initialize the Oracle_101 database interface.
How can we get rid of this error ?

To remove this error, we need to check three things
--Path of variable ORACLE_HOMEshould be set correctly.
--There should be only oracle101.db (oracle90.db for windows only) file exist at CORE_ROOT\4edi\dbload. Move other files to disabled directory.
--Change security mode for UNIX file system under ORACLE_HOME (changed to read and access for other group)
