For sure there will be more RIF's coming. We were told as much when the last big RIF in India started.
India and China have been hit and as I understand it EMEA is in the firing line June / July, at least due to employment laws etc there is some notice period in most countries in Europe and anyone looking for a new role outside would generally be looked on favourably having the big O on their CV.
I jumped on a Zoom a few minutes early yesterday and overheard the subject of headcount and RIF's being talked about in terms of who will be left to handle the workload so something is definately being co-ordinated. Unfortunately its a way of life these days in any big company. I don't honestly think anyone is 100% safe at Oracle.
While being part of a RIF can be horrible I can say from experience it can also be very empowering when you realize other companies value your skills way more highly than they are valued at Oracle
