at least to become transparent to the end users, unless of course, ora-19502 ora-27072 the following points are blocking in your case: 1. ALTER SESSION statements are lost: Statements such as "ALTER ora-19502 write error on file ora-27072 file i/o error 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

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 Additional infor

RMAN abort https://www.ibm.com/developerworks/community/forums/thread.jspa?threadID=164157 with ORA-19502 and ORA-27072 Oracle Database Tips by Burleson Consulting March 16, 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: File I/O error Is this really a file I/O write error 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 phantom I/O error (as when the disk file is full), and the OS write error on 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.

Unanswered question This question has not been answered yet. Hello, I have an single lpar on p570 with 5300-05-06. Today i noticed lots of messages in the errpt log that keep on comming every single minute: LABEL: J2_USERDATA_EIO IDENTIFIER: EA88F829 Date/Time: Wed May 30 13:25:13 2007 Sequence Number: 1868 Machine Id: 00C398DE4C00 Node Id: miranda Class: O Type: INFO Resource Name: SYSJ2 Description USER DATA I/O ERROR Probable Causes ADAPTER HARDWARE OR MICROCODE DISK DRIVE HARDWARE OR MICROCODE SOFTWARE DEVICE DRIVER STORAGE CABLE LOOSE, DEFECTIVE, OR UNTERMINATED Recommended Actions CHECK CABLES AND THEIR CONNECTIONS INSTALL LATEST ADAPTER AND DRIVE MICROCODE INSTALL LATEST STORAGE DEVICE DRIVERS IF PROBLEM PERSISTS, CONTACT APPROPRIATE SERVICE REPRESENTATIVE Detail Data JFS2 MAJOR/MINOR DEVICE NUMBER 000A 0006 FILE SYSTEM DEVICE AND MOUNT POINT /dev/hd9var, /var The OS is working normaly haven't crashed or anything it's just those messages, nothing in the config of the lpar or the OS have been changed in the last week or so. Only change to that box was an upgrade of the FW to: Platform Firmware level: SF240_299 Firmware Version: IBM,SF240_299 Without shutting down the lpar and activating it again. lsvg rootvg looks OK, no stale PVs or anything. No PTFs or APARs applied to the OS after the SP6 of TL5. Anyone has any idea what this could be? Searched google without much luck. Thanks in advance. Log in to reply.

This is the accepted answer. OK so here is what happend, looks like the var lvol got corrupted and you could touch a file but one wasn't able to fill it in with some data and after running fsck on mounted FS (i know it's not a good idea to run it on mounted FS, the "man" says that fsck does a read-only check on mounted FS and since that fsck was a blind shot (call me a AIX noob if you will) since i had no ideas what this could be) i got: Block allocation map is corrupt (NOT FIXED) Block allocation map is corrupt Guess that was the problem, booting in maint mode and running fsck again fixed it and now i don't have any of the previous errors. Hope this is helpfull to s
