Table Shrinking in Oracle Database
 
14:15
1.Shrink the Table: Shrinking is started from 10g. In this method I’m using user u1 and table name sm1. Now I’m deleting some rows in sm1 COUNT ---------- 1048576 Table sm1 has 1048576 rows. [email protected]: delete from sm1 where deptno=10; 262144 rows deleted. I deleted above number of rows. Rows COUNT ---------- 786432 And I’m giving commit [email protected]: commit; Commit complete. So now we have 786432 rows in sm1 table. Now see the following command [email protected]: select OWNER,TABLESPACE_NAME,SEGMENT_NAME,SEGMENT_TYPE,BYTES/1024/1024||' mb'"space",BLOCKS,EXTENTS from dba_segments where tablespace_name like 'U%TS'; OWNER TABLESPACE_NAME SEGMENT_NAME SEGMENT_TYPE space BLOCKS EXTENTS ----- --------------- ------------- ------------- ------ ---------- ---------- U1 U1TS SM1 TABLE 29 mb 3712 44 After I deleted some rows in sm1 table still above result showing same values, so now our duty is shrink this table. This is done by following 2 ways, i By using COMPACT key word: In this method shrinking is done in two phases. In the first phase all fragmented space are just defragmented, but still the High Water Mark is persist with last used block only. That mean used free blocks are not de allocated and HWM is not updated here. Issue the following command before use shrink command. [email protected] alter table sm1 enable row movement; Table altered. There is particular use with above command, when we shrink the table all rows are moves to contiguous blocks, so here row movement should be done. By default the row movement is disabled for any table, so above command enabled the row movement. Then execute shrink command now. [email protected]: alter table sm1 shrink space compact; Table altered. Now see the space of table by using below command. [email protected]: select OWNER,TABLESPACE_NAME,SEGMENT_NAME,SEGMENT_TYPE,BYTES/1024/1024||' mb'"space",BLOCKS,EXTENTS from dba_segments where tablespace_name like 'U%TS'; OWNER TABLESPACE_NAME SEGMENT_NAME SEGMENT_TYPE space BLOCKS EXTENTS ----- --------------- ------------- ------------- ------ ---------- ---------- U1 U1TS SM1 TABLE 29 mb 3712 44 So here seems nothing happened with above shrink command, but internally the fragmented space is defragmented. But the high water mark is not updated, used free blocks are also not de allocated. For de allocating the used blocks we have to execute below command. This is the second phase. [email protected]: alter table sm1 shrink space; Table altered. Now see the space by using below command. [email protected]: select OWNER,TABLESPACE_NAME,SEGMENT_NAME,SEGMENT_TYPE,BYTES/1024/1024||' mb'"space",BLOCKS,EXTENTS from dba_segments where tablespace_name like 'U%TS'; OWNER TABLESPACE_NAME SEGMENT_NAME SEGMENT_TYPE space BLOCKS EXTENTS ----- --------------- ------------- ------------- ---------- ---------- ---------- U1 U1TS SM1 TABLE 20.8125 mb 2664 36 So now the space of sm1 table is reduced. Note: Actually the alter table sm1 shrink space command will complete these two phases of the shrinking of table at a time. But here we done shrink process in two phases because when we use alter table sm1 shrink space command the table locked temporarily some time period, during this period users unable to access the table. So if we use alter table sm1 shrink space compact command the table is not locked but space is defragmented. When we not in business hours issue the second phase shrink command then users are won’t get any problem. ii Because of above method the table dependent objects are goes to invalid state, to overcome this problem we have to use below command. [email protected]: alter table sm1 shrink space cascade; Table altered. The above command also shrinks the space of all dependent objects. We also do this in two phases like above two phases. See the below command. [email protected]: alter table sm1 shrink space compact cascade; Table altered. And then [email protected]: alter table sm1 shrink space cascade; Table altered.

1Z0-052 How to create tablespace in Oracle database 11g
 
03:56
A tablespace is a logical storage unit in an Oracle database. It is called logical because a tablespace is not visible in the file system of the machine where the database resides. Each table, index, and file stored in an Oracle database belongs to the tablespace itself. A tablespace acts like a bridge between the Oracle database system and the filesystem in which the table's or index's data is stored. There are three types of tablespaces: Permanent tablespaces, Undo tablespaces and Temporary tablespaces.

RMAN: backup tablespace DEMO1; We need to put the DB in archivelog first Rebuild index with NOLOGGING option to simulate soft corruption later. RMAN: alter index idx_obj_name rebuild nologging; Confirm that we have datafiles that require backup because they have been affected with NOLOGGING operation. RMAN: report unrecoverable; Simulate corruption. RMAN: alter database datafile 5 offline; RMAN: restore datafile 5; RMAN: recover datafile 5; RMAN: alter database datafile 5 online; Query table with corrupted index and notice error. SQL: select count#*$ from objects where object_name like 'A%'; Let’s perform validation of datafile to check block corruption. RMAN: backup validate check logical datafile 5; Notice that we have 457 blocks marked corrupt but v$database_block_corruption view is empty. SQL: select count#*$ from v$database_block_corruption; Let’s query v$nonlogged_block view. set lines 200 set pages 999 select file#, block#, blocks,object#,reason from v$nonlogged_block; Will RMAN detect that we have corrupted blocks? RMAN: backup datafile 5; RMAN backup won’t fail due to NOLOGGING corrupt blocks and our backup will contain soft corrupted blocks. Let’s Identify corrupt segments using v$nonlogged_block view. set lines 2000 set pages 9999 col owner for a20 col partition_name for a10 col segment_name for a20 SELECT e.owner, e.segment_type, e.segment_name, e.partition_name, c.file# , greatest#e.block_id, c.block#$ corr_start_block# , least#e.block_id+e.blocks-1, c.block#+c.blocks-1$ corr_end_block# , least#e.block_id+e.blocks-1, c.block#+c.blocks-1$ - greatest#e.block_id, c.block#$ + 1 blocks_corrupted FROM dba_extents e, V$NONLOGGED_BLOCK c WHERE e.file_id = c.file# AND e.block_id "= c.block# + c.blocks - 1 AND e.block_id + e.blocks - 1 := c.block# UNION SELECT s.owner, s.segment_type, s.segment_name, s.partition_name, c.file# , header_block corr_start_block# , header_block corr_end_block# , 1 blocks_corrupted FROM dba_segments s, V$NONLOGGED_BLOCK c WHERE s.header_file = c.file# AND s.header_block between c.block# and c.block# + c.blocks - 1 UNION SELECT null owner, null segment_type, null segment_name, null partition_name, c.file# , greatest#f.block_id, c.block#$ corr_start_block# , least#f.block_id+f.blocks-1, c.block#+c.blocks-1$ corr_end_block# , least#f.block_id+f.blocks-1, c.block#+c.blocks-1$ - greatest#f.block_id, c.block#$ + 1 blocks_corrupted FROM dba_free_space f, V$NONLOGGED_BLOCK c WHERE f.file_id = c.file# AND f.block_id "= c.block# + c.blocks - 1 AND f.block_id + f.blocks - 1 := c.block# order by file#, corr_start_block# / This is the best outcome to get if you notice corruption errors. All errors are related to index corruption so we could fix this problem rebuilding index. alter index idx_obj_name rebuild; Simply issuing "alter index rebuild" command won't work. We should mark index unusable to drop segment before rebuilding it or just rebuild index with online option. It is better choice to mark index unusable because you don't need additional space then, but I will simply rebuild index with online option and see what will happen. SQL: alter index idx_obj_name rebuild online; Index altered. SQL: select count#*$ from objects where object_name like 'A%'; No errors... but, let's validate datafile for corruption. RMAN: backup validate check logical datafile 5; Notice "Marked Corrupt" column. Hm... 457 like before. Don't worry, this is not new corruption. These are FREE blocks which will be reused and Oracle will automatically re-format those blocks. Query the v$nonlogged_block view again as given above. We could force re-formatting creating dummy table and inserting data to dummy table. Check Doc ID 336133.1. create table s # n number, c varchar2#4000$ $ nologging tablespace DEMO1; SQL: BEGIN FOR i IN 1..1000000 LOOP INSERT /*+ APPEND */ INTO sys.s select i, lpad#'REFORMAT',3092, 'R'$ from dual; commit ; END LOOP; END; / SQL: drop table sys.s purge; Notice that we don't have corrupted blocks any more. RMAN: backup validate check logical datafile 5;

Basics of Oracle Internal Structure - Database Tutorial 43
 
10:27
Video 43 Basics of Oracle Internal Structure This video explains the basics of Oracle Internal Structure. Inside the Oracle database, everything gets stored in Tablespaces. A tablespace is a logical structure that is made up of one or multiple data files. The operating can only see the data files. For it, these files are just like other files. But, once these files are properly opened up by Oracle, then they present a logical structure called Tablespace within Oracle. It is important to remember, tablespaces are logical structure that can be seen only from inside of Oracle. Outside of it, that is, from the Operating System's perspective, they would be nothing but a bunch of data files. For an user to log in to the database he/she must have an user account within that database. These users are called just 'users'. However, users can be granted privileges to create tables or indexes or other objects. And if an user creates a table, that is owned by that user, then that user can also be called as a schema.

Oracle Tablespaces - Database Tutorial 56 - Oracle DBA Tutorial This video explains about Oracle Tablespaces. Oracle Tablespaces are the storage containers where the objects such as Tables, Indexes etc will be stored. A Tablespace is formed using one or mode data files. A Data file can belong to only one Tablespace. But a Tablespace can have multiple data files.

How to move a Datafile in Oracle Database 12c - part 2
 
01:26
How do you move a datafile in an Oracle Database? Well, it just got a lot easier in 12c! Watch this free video tutorial where OCM John Watson of SkillBuilders will demonstrate both techniques, 11g and 12c. http://skillbuilders.com/free-oracle-tutorials There are many reasons to move a datafile in an Oracle database. Here are just a few: Renaming datafiles to a standard Moving from one file system to another Converting from file system storage to ASM Changing from SAN to NFS storage In 11g, we need to take the tablespace offline, meaning downtime. Argh! In 12c, all that is required is ALTER DATABASE MOVE DATAFILE; this is an online operation with zero downtime (in 11g we use ALTER DATABASE RENAME DATAFILE). Even "critical" files such as the files associated with the SYSTEM tablespace can be moved online. Consider the ease of moving to ASM this provides! This also functions in an Active Data Guard standby environment. And, there are syntax options that allow you to keep or delete the original file. Very cool stuff.

Define Segment, Extent, Block (Hindi) | Prof. Jayesh Umre
 
06:20
Solution to the question submitted by students. Define Segment, Extent and Block? (RGPV Dec 2014,Dec 2010, Dec 2009) Sol. Block: A database block is the smallest unit of storage in Oracle. Oracle manages the storage space in the datafiles of its database in these units. The size of block is a specific number of bytes of storage within a given tablespace. The default block size is specified by the Oracle initialization parameter that is DB_BLOCK_SIZE. Extent: An extent is the next level of logical grouping in the database. An extent consist of one or more database blocks. When we enlarge a database object, the spece added to the object is allocated as an extent. Segment: Segment is a group of extents that form a database object that oracle treats as a unit, such as table. There are four types of segments- Data segment – It is a storage part. Index segment – Its hold all of its data. Temporary segment – It’s a temporary work space. Undo segment – to do transaction undo
