Re: Dbspace question

Posted By: Kern Doe

In Response To: RE: Dbspace question (Larry Sorensen)

Say, your database (source) created in dbs1 but all your tables are in dbs2, when you do onload (to target), of course, you must specify -d dbs1 (it is where the database is in), but all your tables are automagically onloaded to dbs2 -- as far as I remember.

HOWEVER, I must mention this issue based on my past experience involving onunload/onload with older version of IDS (9.4?) was that if you have created dbspaces with different page sizes, onunload of database level appears to work but then onload will fail -- I have not tried with the latest version so I do not know if IBM has fixed this bug.

I encourage you to test all these out to see for yourself.

So, what you are thinking is that, if I do not use onload -d dbspace (the -d
option), it will just use the same dbspaces as the unload came from rather
than the rootdbs, which I was worried it might?

continue using onunload and onload, it should work as long as your target
instance has identical or similar dbspace layout. Why don't you test it out,
it should take 15 min and you'll know the answer.
For example, generate a schema of your source database but modify or comment
out extent sizes (to save space). On the target instance, recreate the same
database with this schema. Now run onunload, drop the database, then onload
