Hi everyone,
We have a 10g database with over 3.5 TB of data. This supports a
SAPR3 application. However, this database has been upgraded twice since
it was originally created and the upgrade went from 8i to 9i to 10gr2.
It has come to be somewhat unmanageable since It's so big and most
tablespaces are 'Dictionary Managed' (thanks 8i). We have been trying to
solve this by migrating the tablespaces to locally managed, but there
are a couple of tablespaces that are humongous and simply there is not
enough time during a weekend to do this change. CT cannot tolerate any
more downtime. At this point we are drawing a blank... so I thought I
could ask over here, perhaps someone has a little experience with these
sort of issues.
I considered creating a second database (which would require about
3.5 TB of temporary storage), and using streams or datapump to move all
the data... however I never implemented streams in this way and am not
certain it could be done.
Thanks in advanced.
