I am trying to find out the rman memory usage when backup jobs are run. i am looking at a job now from backup_async_io:

Does this mean for the currently active channels 16Mb, 16Mb and 4Mb of mem is being used?

Thanks
Ram.

Which OS? If it is some kind of Unix, I would check the /proc file system. It usually provides an excellent information about memory usage.
