Then create a backup script via Rman:

[email protected] dbs]$ Rman target/catalog rman/[email protected]

Recovery manager:release 11.2.0.1.0-production on Tue APR 7 11:29:41 2015

4> Delete noprompt expired archivelog all;
5> Allocate channel CH1 device type disk;
6> Delete noprompt Obsolete recovery window of the days;
7> release channel CH1;
8>}

This is the backup script built successfully!

Note:

In the back of the same error, after the operating system deleted the trace file "Blk.trc", and back to normal, and now have not figured out the specific cause of the problem is what?
