All, I'm seeing this strange intermittent happening with Data Guard that I can't explain & it seems that OTS can't either. About once a month, or less, I end up with a gap at the standby location, but the log file is there. I'll then try registering it and catch an "ORA-00317: file type 0 in header is not log file" error. I'll then remove the file & let the fetch archive log process do its thing only to see the gap still there 30 minutes later, same file & once again it's on the standby. Again I'll try to register it & get the same error again. But if I binary ftp the file to the log_archive_dest_1 location but with a slightly modified file name, .dbf0 instead of .dbf, & register it with the modified file name it works as advertised. Can't understand the initial error. Anyone else ever see this behavior??? ______________________________________________________________ Dick Goulet / Capgemini North America P&C / East Business Unit Senior Oracle DBA / Hosting Office: 508.573.1978 / Mobile: 508.742.5795 / www.capgemini.com Fax: 508.229.2019 / Email: richard.goulet@xxxxxxxxxxxxx 45 Bartlett St. / Marlborough, MA 01752 Together: the Collaborative Business Experience ______________________________________________________________ This message contains information that may be privileged or confidential and is the property of the Capgemini Group.
