Re: Deallocate channel vs Release channel in RMAN

Rick,

There is no RMAN command deallocate Channel, only release channel.

When you allocate a channel, causes operating system resources to be allocated depends on your operating system. On some platforms, operating system resources are allocated at the time the command is issued. On other platforms, operating system resources are not allocated until you open a file for reading or writing.

In the doc for Release Channel it says : To release a channel while maintaining the connection to the target database instance. Specify the channel name with the same identifier used in the allocate channel command. This command is optional; RMAN automatically releases all channels allocated when the run command terminates.

HTH,
Tammy
