tablespace

问题 I have a partitioned table that belongs to tablespace report . I want to move it to tablespace record instead. One possibility is to drop the table and recreate it in the new tablespace, but that is not an option for me, since there is data in the table that needs to survive the move. I started by checking that the partitions actually belong to tablespace report with: SELECT * FROM user_tab_partitions WHERE table_name = 'REQUESTLOG'; Then I just tried: ALTER TABLE requestLog MOVE TABLESPACE

问题 SQL to check the free space allocated for a user who doesn’t have DBA access. preciously in oracle 11G it was possible to use the “user_free_space” View but from oracle 12 c this view access is restricted to DBA users.

问题 This is a practice assignment where I have to create a table space with two datafiles. We have to use the exact naming conventions that are given to us. I believe I have it right, but I get this error: " ORA-00972: identifier is too long ". I think I'm getting this because the path and filename are so long. The question is, how do I get around this? Thanks! CREATE TABLESPACE CTTT444_tbs DATAFILE "C:\oracle\product\10.2.0\oradata\cttt444_1.dbf" SIZE 15M, DATAFILE "C:\oracle\product\10.2.0

问题 I need to check space used by a tablespace but I have no dba privs. Is there a way to do this? 回答1: Unfortunately without explicit permissions to the dba_free_space or dba_segments views you are stuck with your users default tablespace: SELECT ts.tablespace_name, TO_CHAR(SUM(NVL(fs.bytes,0))/1024/1024, '99,999,990.99') AS MB_FREE FROM user_free_space fs, user_tablespaces ts, user_users us WHERE fs.tablespace_name(+) = ts.tablespace_name AND ts.tablespace_name(+) = us.default_tablespace GROUP

问题 Hi Can some let me know why we created different table space for Index and data. 回答1: It is a widespread belief that keeping indexes and tables in separate tablespaces improves performance. This is now considered a myth by many respectable experts (see this Ask Tom thread - search for "myth"), but is still a common practice because old habits die hard!
