using ttbs to change block size

edited Sep 9, 2016 5:01AM in Database Administration (MOSC) 5 commentsAnswered

dear all,

I have a DB with 8KB block size.

On the same server I've create a DB with 32KB Block size, and a non-default buffer db_8k_cache_size = 10G.

Both DBs = 11.2.0.4 running on the same server Linux 64.

I used the following link to move all user tablespaces from the original 8kb to the new db without changing the datafiles location.

https://docs.oracle.com/cd/B28359_01/server.111/b28310/tspaces013.htm

which steps should I do, and should I do not, as long as I do not change neither the OS nor the Data Files location?

PS: I'm using this way to change block size because this will minimize the downtime, as we could use normal methods "alter table move, dbms_redifintion" to move segments from non-default block size tbss to normal one, after they are pluged to the new db.

Howdy, Stranger!
