--===============0388671869== Content-class: urn:content-classes:message Content-Type: multipart/alternative; boundary="----_=_NextPart_001_01C5B4A2.02DF5E85" This is a multi-part message in MIME format. ------_=_NextPart_001_01C5B4A2.02DF5E85 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: quoted-printable We have nearly 200 GB of data in a production Oracle database broken up into about 100 files of 2 GB. The database incurrs a 5% change per week in the form of new data, no modification nor deletions. I need to copy this data from one mount point to another then bring up the new database on the new mount point in place of the original. The high availability and production nature of this system means that my maintenance windows are few and far between. To minimize my use of the maint window, I would like to pre-copy as much data as I can with RSYNC before the window, then do a final sync of the data during the window with the database down. My question is, will RSYNC be a good option given that the Oracle database is up and running for the initial sync? I'm hoping that RSYNC will be an option for us, as other mirroring strategies I have seen rely upon same size disk devices/partitions, which we do not want because the goal is to put up a single device larger area to keep this data. Please ignore the gaping holes for ideas such as just having Oracle use another mount point in addition to the one it is already using or online VG expansions. =20 David Poe ------_=_NextPart_001_01C5B4A2.02DF5E85 Content-Type: text/html; charset="us-ascii" Content-Transfer-Encoding: quoted-printable <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN"> <HTML><HEAD><TITLE>Message</TITLE> <META http-equiv=3DContent-Type content=3D"text/html; = charset=3Dus-ascii"> <META content=3D"MSHTML 6.00.2800.1515" name=3DGENERATOR></HEAD> <BODY> <DIV><SPAN class=3D230305617-08092005><FONT face=3DArial size=3D2>We = have nearly 200=20 GB of data in a production Oracle database broken up into = about 100=20 files of 2 GB.
