Hi,
I see that the stream count is defaulted to 2. But I also read the all restores are single streamed except for a few iDAs. And oracle iDA is not one of them.
Regards,
Pedro
Do Oracle DB restores supports multiple streams?

Hi,
I notice that changing the stream count to higher number caused RMAN to allocate and use more channels during the datafile restoration process.
What does that mean?
I notice though that archive log restore operation used only one channel.

Pedro
Hi
I am pretty sure you can run multiple channels with RMAN, but this depends whether you have Standard or Enterprise Edition of Oracle from memory - Standard only allows one channel
I looked at this many years ago, to speed up some Oracle backups / restore times which luckily had Enterprise Edition
You had to backup with multiple streams, to restore with multiple streams eg: 1 backup stream cannot be two restore streams!

Hi
As per this article: https://documentation.commvault.com/2023e/expert/92576_multi_stream_restore_operations.html
Oracle doesn’t support multiple stream restores:
Hopefully this helps,

Is this something that will be changing in the future or is there a feature request for multiple streams for Oracle iDA restores?
