ONEDB_HOME environment variable

The ONEDB_HOME environment variable specifies the directory that contains the subdirectories in which your product files are installed. You must always set ONEDB_HOME. Verify that ONEDB_HOME is set to the full pathname of the directory in which you installed your database server. If you have multiple versions of a database server, set ONEDB_HOME to the appropriate directory name for the version that you want to access. For information about when to set ONEDB_HOME, see your HCL OneDB™ Installation Guide.
