Enable and disable dSource hooks

Some dSources are linked to production systems, where hooks can execute with the privileges of the Delphix Environment User account. To reduce risk on production hosts, dSource hooks should remain disabled unless they are required for approved operational use cases.

Impacted dSources types

Only dSource types where hooks execute on production hosts are impacted by this control.

• For Oracle, dSources using Delphix initiated backups.

• For AppData, dSources which use "Direct ingestion” mechanism.

This control does not apply to hooks that execute on staging hosts or VDB target hosts.
