RE: [U2] [UV] FAST Running while system in use
And I should clarify that the biggest part of my nightmare was having someone do a RESIZE CONCURRENT on one of the largest major most utilized files during business hours... uhhh -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of Mitchell, Stewart Sent: Saturday, April 22, 2006 12:04 AM To: 'Debster'; 'u2-users@listserver.u2ug.org' Subject: RE: [U2] [UV] FAST Running while system in use Hi Debster, Thanks for your suggestions.

RE: [U2] [UV] FAST Running while system in use
Stewart, The FAST Gather Statistics and Type Analysis processes can be safely run while other users are accessing the files. The FAST processes are read only and use no locks are other mechanisms that would interfere with access to the files. Of course, if the files were being heavily updated it could cause the calculations to be inaccurate but that would be the worst that might happen. Only the Resize process cannot be safely run with other uses in the files. Hope this helps! Please feel free to contact us for help at [EMAIL PROTECTED] if further questions arise.
