Hey Chris,  

Note:62290.1 on Metalink has all of the steps you need to follow...  

But the basic steps are:  

  1. Backup your current environment software and database.
  2. Install the 32bit software.
  3. copy over your parameter, password files, etc to the new Oracle home.
  4. Point your environment to the new Oracle Home
  5. Startup migrate and rebuild the dictionary: catalog, cataproc and utlirp

I believe thats it but make sure you read that metalink note.

Subject: 64-bit -> 32-bit 32-bit linux was just released.  

We are hitting a number of OLAP bugs in that are supposedly fixed in 64-bit linux won't be out for another month or so (so we are told).  

We are seriously considering migrating to 32-bit version in the meantime but I don't fully understand the consequences of doing so.  

  1. Is is just a matter of installing 32bit and bringing up the database under the 32bit home? ...or do i have to go the export/import route?
  2. Is there any good reason not to do this?

thanks for any help.  

i also have an sr open with oracle to figure this stuff out and will be researching this today.  

i will post what i find if anyone is interested.
