RAC backup error solved

Check the Rman backup log in the early morning and find an error. The error is as follows:

RMAN-00571: ========================================================
RMAN-00569: ========= error message stack follows ============
RMAN-00571: ==========================================================
RMAN-03009: failure of backup command on d2 channel at 06/27/2007 05:06:17
ORA-19504: failed to create file "/data/rman/archivelog/MEM_20070627_349_1.arc"
ORA-27040: file create error, unable to create file
Linux Error: 2: No such file or directory

Take a closer look at the error and analyze the cause as follows:
Since the database to be backed up is a Linux RAC, only one of the instances is connected when archiving logs are backed up. when you back up the archiving logs of another instance, the error occurs because no corresponding directory is created on the server! Locate, and create the desired directory!
