In order to use the Oracle Extension, you must first create an alias in the Borland Database Engine (BDE) for your source
                  data store to communicate with the Oracle client installed on your machine. A BDE alias is not required for your target data
                  store. 
                  	  
               
            
 
            	 
             
               		Note: 
               	 
            
 
            	 
             
               		
               -  For your source Oracle data store specified for either the Distributed Loader or Distributed Exporter, you must create a
                  BDE alias. We recommend that the associated BDE alias match the Oracle TNS service name specified in your 
                  		  tnsnames.ora file. 
                  		
               
-  For your target Oracle data store specified in the Distributed Exporter, make sure that the target name is the Oracle TNS
                  service name specified in your 
                  		  tnsnames.ora file located on the machine where you intend to mask/subset data. 
                  		
               
- If you are using Data Express on Windows Vista and User Access Control is enabled, you must run the BDE Administrator utility
                  as 
                  		  Administrator. 
                  		
               
To create an Oracle alias: 
               	 
            
 
            	 
             
               		
               -  Open BDE Administrator (from the 
                  		  Control Panel). Click the 
                  		  Configuration tab, and then select 
                  		  ORACLE from the 
                  		  Native Drivers list as shown in 
                  		  Figure A-1: 
                  		
               
-  In the 
                  		  Definition of ORACLE pane, click in the second column for 
                  		  DLL32 to display a list of DLLs. Select 
                  		  SQLORA8.DLL, and click 
                  		  Object > 
                  		  Apply as shown in 
                  		  Figure A-2: 
                  		
               
-  3. In the 
                  		  Definition of ORACLE pane, click in the second column for 
                  		  VENDOR INIT, and enter 
                  		  OCI.DLL as the Vendor DLL file name. 
                  		
               
-  4. In the 
                  		  Drivers and System pane, click the 
                  		  Databases tab. 
                  		
               
-  5. Create a new Oracle database alias (right-click, select 
                  		  New, select the Database Driver Name 
                  		  ORACLE, and then 
                  		  OK) and rename the alias as appropriate. 
                  		
               
-  6. In the 
                  		  Definition of 
                     			 AliasName 
                     		   pane, click in the second column for 
                  		  SERVER NAME, and enter your Oracle TNS.
