A lot of kind people write me, concerned I may be breaking the law by saying you have to be a Church member. It's legal I promise! :-) ________________________________ From: Jared Still <jkstill@xxxxxxxxx> To: wjwagman@xxxxxxxxxxx Cc: oracle-l <oracle-l@xxxxxxxxxxxxx> Sent: Friday, January 9, 2009 4:42:44 PM Subject: Re: Question re Database Duplication On Fri, Jan 9, 2009 at 3:28 PM, William Wagman <wjwagman@xxxxxxxxxxx> wrote: ... 1) going from 32-bit to 64-bit 2) going from 10.2.0.3 to 10.2.0.4 3) going from SE to EE I am pretty certain this isn't going to work, I don't believe OEM and RMAN have the intelligence built in to make the changes and I suspect I will have to use expdp/impdp but am just wondering if anyone has any further thoughts. Unfortunately I don't have an environment in which to test this. A few months ago I migrated a 32 bit 9.2 database to 10.2.0.2 on a 64 bit server, all at once. RMAN was not used. This was an SAP database, and a custom version of the dbua was employed. No, I don't know what was different about this dbua. :) The point is that the procedure can be done, but I can't tell you if OEM/RMAN is capable of doing this. Further thoughts: You absolutely need an environment to test this in. There are too many moving parts to try this and expect it to work in production. There is a document on ML detailing 32bit -> 64bit conversions. Jared Still Certifiable Oracle DBA and Part Time Perl Evangelist
