Home -> Community -> Mailing Lists -> Oracle-L -> Changing the Staus of a Database to Read Only
I tried to post this in response to the "Best Practices" thread, but for unkown reasons it didn't seem to make it. My apologies if this is a repeat.
It had been stated that placing each partition in a separate tablespace allowed one to make a tablespace read only once that partition would no longer be used for insert/update/delete operations. I have not tried to switch a database from online to read only after 8.1.6, but as of that release doing so was difficult in an active database. Oracle required not only that there be no active transactions against the tablspace to be converted but no such transactions against the entire database.
If this has changed, when did it happen? We have a system where the ability to make a tablespace read only while the database is actively processing transactions bound for other tablespaces would be extremely useful.
