Re: replacing mounted rootdbs as raw diskspace

Sukmar, 1. it really improves performance to use raw when you're on Unix because it minimizes OS interference with reads and writes (a simplistic answer). 2. migration should be a snap. Something like, - create sufficient raw space on a partition (divvy or the tool your system provides) - soft link the raw device to a file name that makes sense to you, e.g. mydatabase - skip this if you've already defined the rootdbs and the dbspace it resides in - if you haven't yet defined or configured the new rootdbs, start onmonitor and set all the parameters and initialize - export old, import old to new dbexport dbname -ss (check the options) dbimport dbname -d dbspacename (raw dbspace) This is sketchy and you'll probably, as usual, have to resort to the manuals. Actually they're not half bad. Hope this helps. Yours, Nick At 07:17 AM 6/24/98 -0500, sukumar konduru wrote: >Hi > >Our "rootdbs" has been created as mounted file system rather than raw >disk space.
