the following points are blocking in your case: 1. ALTER SESSION statements are lost: Statements such as "ALTER

SESSION ..." are not automatically re-issued to the server following a failover. This can have a significant effect on application behavior. For example: ALTER SESSION SET NLS_DATE_FORMAT='YYYY-MM-DD'; select sysdate from

Continuing work on existing cursors may raise an error (eg: ORA-25401 "cannot continue fetches") 4. Failed over selects may take time to re-position (when FAILOVER_TYPE=SELECT) 5. Client awareness of a Failover Can we have an overview of the disk i o error usb boot database setup, nature of transactions, and parameters? It would also help to examine the troublesome node behavior and recovery measures.

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: write error on file "/u03/arch/2_1917_656008464.dbf", block number 155649 (block size=512) ORA-27072: File I/O error Linux-x86_64 Error: 5: Input/output error Additi

RMAN abort with ORA-19502 and ORA-27072 Oracle Database Tips by Burleson Consulting March 16, http://www.dba-village.com/village/dvp_forum.OpenThread?ThreadIdA=44741&DestinationA=RSS 2015 Question: I lam trying to run an RMAN backup and I am getting the ORA-19502 and ORA-27072 error: ORA-19502: write error on file "/orabackup/rman/snlprod/control_files/c-225853591-20150315-01", block number 320 (block size=16384)ORA-27072: disk i File I/O error Is this really a file I/O error or is it just not enough disk spac for the backup? How to I get my RMAN backup to complete? Answer: This sounds like a file-full or a disk I/O failure to me, Your first step is to see if you have a "real" disk I/O error, and not a disk i o phantom I/O error (as when the disk file is full), and the OS logs will provide this information. SQL> select * from V$DATABASE_BLOCK_CORRUPTION; This error is related to the RMAN disk I/O failure. The backupis attempting to write to a larger disk space than is available. It can also happen when a 2 gigabyte file size has been reached. Make sure oracle software owner (oracle user, by default) at OS level has full permissions on the file system under the new mount point. If everything is OK, configure the disk channel explicitly and see if it works.The reason for this error is that there is not enough disk space on the drive to complete the backup piece. To resolve this error, either clean up unnecessary files on the disk, or add disk space to the disk then re-run the RMAN backup.
