What Do Oracle Audit Vault Collection Agents Do?
The Oracle Audit Vault is installed on a server, and collector agents are installed on the hosts running the source databases. These collector agents communicate with the audit vault server.
If the collection agents are not active, no audit data is lost, as long as the source database continues to collect the audit data. When the collection agent is restarted, it will capture the audit data that the source database had collected during the time the collection agent was inactive.
