vRealize Operations for Horizon requires that you have an event database to store information about Horizon events. You can store events in a SQL database or an Oracle database.

For supported database versions, see Database Requirements for View Composer and the Events Database in the Horizon 7 Installation document.

If you use an Oracle event database, a recent version of Oracle Data Access Components (ODAC) and Oracle Instant Client (Basic or Basic Light package) must be installed on your system.

For more information, see Oracle Event Databases.
