Home -> Community -> Mailing Lists -> Oracle-L -> How to precreate tables for migration?
So,
We're taking the leap from 8.0.6 to 8.1.7. For various reasons, we will be using the export/import method of migration.
Since I'll have the DB all to myself for the weekend, I want to also partition most of our larger tables (1M-7M rows each -- it's not a huge DB) in the migration. My plan to precreate the tables was to:
(I've left out many migration steps not pertinent to this question)
Obviously, step 4 can't go before step 5, as step 5 creates the schemas.
So, my questions: Has anyone precreated tables before a full import on a clean DB? Did you just manually precreate the schemas? How does the import deal with this (e.g. the DESTROY arg for imp)? Or would it be OK to skip step 4 and delete/rebuild the tables to be partitioned after the import had rebuilt them? I would prefer not to do the latter, seeing as this will be the first time in three years that the TSs will be nice and contiguous. :)
Also, for brevity, we won't be going LMT for most of our TSs. Need too much time to plan for that... :(
TIA!
