Consider a system that processes files uploaded by ftp to the DB server. Currently the upload directory is polled periodically for new files (since they don't all arrive on a predictable schedule with predictable names). Any new files are processed and then moved to an archive location so that they aren't reprocessed. The polling and processing is done by java stored procedures. This system is a RAC system with no shared filesystem storage. The jobs that poll run on a particular instance via the 10g Job Class trick. The question that I have is how would you implement resilience to node failure for this system. It seems to me that we could do * add shared storage - at a cost probably. * ftp the files directly to the db - implies code changes probably Does anyone else do anything similar and if so how? -- Niall Litchfield Oracle DBA http://www.orawin.info ______________________________________________________________________ Wm Morrison Supermarkets Plc is registered in England with number 358949.
