Last Updated March 05, 2019
You are upgrading the DLP Enforce Server to 15.x from a prior version. You are able to connect to the Oracle DB using SQLPlus, but when you run the Symantec Data Loss Prevention 15.x Enforce Server set up MSI, you receive the error:
Error calling OCIServerAttach for database <//IPADDRESS:PORT/ServiceName>: ORA-12154: TNS:could not resolve the connect identifier specified.
Note that the values in the angle brackets will reflect those of your environment.
Uninstall the Oracle Client on the Enforce server
Reboot the server
Install the Oracle Client provided by Symantec for the version of Oracle you are running (either 11.2.04 or 12.2.01)
On the Select Installation Type, be sure to select the ‘Administrator’ button during the installation
