Create Tablespace in ORACLE 10g



Create Tablespace in ORACLE 10g
Permanent tablespace
Adding Tablespace in database:

CREATE SMALLFILE TABLESPACE BU_SYSTEM_TBS DATAFILE '$DATAFILE_LOCATION/BU_SYSTEM_TBS' SIZE 100M AUTOEXTEND ON NEXT 1000M MAXSIZE UNLIMITED LOGGING EXTENT MANAGEMENT LOCAL SEGMENT SPACE MANAGEMENT AUTO;


Adding Datafile in a Tablespace:
Use ALTER TABLESPACE to add datafile in tablespace:


ALTER TABLESPACE BU_HIS_LOG_TBS ADD DATAFILE '$DATAFILE_LOCATION/BU_HISTLOG_TBS_01.dbf' SIZE 1000M AUTOEXTEND ON NEXT 20M MAXSIZE UNLIMITED;

Modify Datafile:

You can modify datafile using ALTER DATABASE command:
ALTER DATABASE DATAFILE ’$DATAFILE_LOCATION/data01.dbf’ AUTOEXTEND ON NEXT 30M MAXSIZE 1200M;

which means datafile data02.dbf can automatically grow upto 1200 MB size in blocks of 30 MB each time as required.

Renaming Tablespaces:
This is a feature that is available with Oracle 10g and can be useful in transportable tablespace scenarios.
alter tablespace ts_user rename to ts_user_01;

ALTER TABLESPACE BU_IMAGE TO BU_PICTURE;

Shared Pool Tuning: Cursor Tuning (Tuning Open_Cursors, Session_Cached_Cursors, Cursor_Space_For_Time)

Shared Pool Tuning: Cursor Tuning The three most important parameter for shared pool tuning are OPEN_CURSORS , SESSION_CACHED_CURSORS and CURSOR_SPACE_FOR_TIME. But most of the time we see that these two parameters SESSION_CACHED_CURSORS and CURSOR_SPACE_FOR_TIME are ignored or unused . OPEN CURSORS Open cursors take up space in the shared pool, in the library cache. OPEN_CURSORS sets the maximum number of cursors each session can have open, per session. For example, if OPEN_CURSORS is set to 1000, then each session can have up to 1000 cursors open at one time. V$open_cursor shows cached cursors, not currently open cursors, by session. If you’re wondering how many cursors a session has open, don’t look in v$open_cursor. It shows the cursors in the session cursor cache for each session, not cursors that are actually open.  To monitor open cursors, query v$sesstat where name= ’opened cursors current’ . This will give the number of currently opened cursors, by session:
