Hi:

I need to convert RBS tablespace (used for rollback segments) from DMT to LMT on a 24x7 production machine (Solaris 2.8, Oracle 8173). Here are the steps I am thinking of taking:

1. create a new rbslmt tablespace
2. create new rollback segments (RBSlmt01, RBSlmt02, ... RBSlmt 06) in rbslmt ts , set them online
3. alter all old rollback segments (RBS01, ... RBS06) offline;
4. Drop all old rollback segments;
5. alter old RBS tablespace offline
6. Drop old RBS tablespace
7. Remove old RBS tablespace's datafiles from OS
8. Create new RBS tablespace as LMT
9. Create new rollback segments (RBS01, ... RBS06) in RBS, set them online;
10. alter rollback segments (RBSlmt01, RBSlmt02, ... RBSlmt 06) offline, then drop them;
11. alter tablespace rbslmt offline
12. drop tablespace rbslmt
13. Remove tablespace rbslmt's datafiles from OS.

Anything I am missing?

TIA. Guang
