Hi all!

For the accident, I found that many indexes was created with tablespace SYSTEM, and then, I have got a decision to move them to the other tablespace, USERS.

However, I wonder about them will be rebuilt concurrency when I use the command

SQL> alter index CSN.PS_102007 rebuild tablespace USERS;

Because of more generation redo log file when if index is rebuilt, then I feel to bother.

Thank you for your reply!
