Arc0 I/o Error 19502

Messages sorted by: [ date ] [ thread ] [ subject ] [ author ] Hello Diane, I believe that implementing TAF could help a bit encountered disk i/o error 19502 in this case, at least to become transparent to the end users,
Ora-19502
unless of course, 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 dual; Result> 2009-01-31 << Fail over the connection >> select sysdate from dual; Result> 31-JAN-09 2. In-progress transactions must be rolled back 3. 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

Well, there is a alternative : Oracle Archive dest is exhausted? Well, there is a alternative : Oracle Author: Abu Fazal Abbas Category: Oracle 8 Aug 15 Issues that we face Ideally in a production Oracle database, we enable the archivelog mode for i/o error 19502 the ONLINE redo logs to be archived during log switches. We must also periodically backup and clean up the designated archivelog destination to make room for new archivelogs and avoiding database to go in a hang state. We normally schedule periodic jobs for these backup and clean up operations. However, there are times when unexpected data load happens in the database without the knowledge of DBA and the application faces this so called database hangs and finally they guys managing the applications knock at the DBA's door for help. The next course of actions by the DBA is well known to you and I am not going to waste your time in telling all those stories. What I would like to share today is a very simple method to tackle those unexpected load scenarios where the archivelog destination gets filled up and your periodic backup/cleanup job is yet to be executed. Oracle provides a very simple and straight forward way for the DBA to configure a ALTERNATE (secondary) location for a specific archive destination in a database. What it means is, if Oracle is not able to archive the ONLINE redo logs to a particular archivelog destination (for any reason be it disk being filled up, disk failure, etcetera) it can route t
