The client request id for tracing.
A token that uniquely identifies a request so it can be retried in case of a timeout or server error without risk of executing that same action again. Retry tokens expire after 24 hours, but can be invalidated before then due to conflicting operations. For example, if a resource has been deleted and purged from the system, then a retry of the original creation request might be rejected.
The ocid of the asynchronous request.
For optimistic concurrency control. In the PUT or DELETE call for a resource, set the
if-matchparameter to the value of the etag from a previous GET or POST response for that resource. The resource will be updated or deleted only if the etag you provide matches the resource's current etag value.
