Lately we've been seeing errors on both nodes almost ever other day. The system administrator has checked the SAN array and said there are no issues being reported. Another part of the problem, it appears the instances alter the service_names parameter not allowing new connections to the node with the reported error, but also terminate sessions already connected using the RAC service. The errors all start with - Encountered disk I/O error 19502 - and contain the following: ARC2: Encountered disk I/O error 19502 (ifxdb2) Errors in file /u01/app/oracle/diag/rdbms/ifxdb/ifxdb2/trace/ifxdb2_arc2_15414.trc: ORA-19502: wr

In RMAN I issued: backup database plus archivelog; channel ORA_DISK_1: starting piece 1 at 17-MAR-07 RMAN-00571: =========================================================== RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS =============== RMAN-00571: =========================================================== RMAN-03002: failure of backup command at 03/17/2007 12:12:06 ORA-19502: http://www.dba-oracle.com/t_ora_19502_write_error_on_file_blockno_where_blocksize_equals.htm write error on file "4ceve9st_1_1", blockno 67969 (blocksize=8192) What does this error message mean and how can I fix this? Answer: To diagnose any error, you start by using the oerr utility to fully display the ORA-19502 error: ORA-19502: Write error on file "string", blockno string (blocksize=string) Cause: Write error on output file Action: Check the file This information on ORA-19502 helped to clarify the initial odd-looking message. It's a write error on an output file, just as it says. As a result of the inability to write, it looks like an RMAN backup command failed. In this situation, it turns out the error was an assumption that the location parameter default was set up, but this assumption was not true. Setting the default by issuing a command like the following correct
