ORA-19502

Write error on file: ORA-19502:

 

While trying to take the backup through the RMAN some times we are facing the below error.

RMAN> backup database plus archivelog;

channel ORA_DISK_1: starting piece 1 at 03-OCT-12
RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================
RMAN-03002: failure of backup command at 10/03/2012 12:05:04
ORA-19502: write error on file "4crcv3st_1_1", blockno 5354 (blocksize=8192)

Solution:

As the name it is clear. It is a write error on output file. Check the file then try again.

Check the location parameter default setting by issuing a command like: 

Configure channel 1 device type disk format 'H:\oraback\backup_%U';

It is also possible the backup will be attempting to write to a larger disk space than is available; there is not enough disk space on the drive to complete the backup.
