What is High Water Mark(HVM) in oracle and how it effects the performance of queries?
 
05:41
This video tutorial is to understand the concept of a High Water Mark or HVM of a oracle table, also it states the various changes in the HVM when we perform a insert, delete and Truncate operation on the table, and the video also informs why is the truncate operation more advisable and optimized then the delete operation.

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.

How to Perform Resumable Space Allocation in Oracle. /* Step By Step /*
 
19:56
We can perform Resumable space allocation on Tables. Resumable space allocation, introduced in Oracle 9i, is for all tablespaces at the session level. Database operations are suspended when an out-of-space condition is encountered. These suspended operations automatically resume when the error condition disappears. This feature is very easy to understand. And easy to Implement on any tables.

칼럼 제거 - 칼럼 제거 시 SET UNUSED COLUMN은 해당 칼럼의 데이터를 물리적으로 삭제하는 것이 아니라 사용하지 않는 칼럼으로 Marking 하는 것이다. DROP UNUSED COLUMNS는 UNUSED로 Marking 된 모든 칼럼들을 DROP 한다. Row Chain & Row Migration - Row Chaining이란 Data Block 하나에 전부 입력할 수 없는 Row가 여러 Block에 걸쳐서 입력되는 것을 말한다. - Row Chain이 발생 하면 Chain이 발생한 Row를 조회 시 하나 이상의 Block에 대해 I/O가 발생하므로 성능을 저하 시키는 요인이 된다. - 이러한 Row Chaining 현상은 해결하기 위해 Row Migration이라는 기법을 이용한다. (일부 저장 용량의 손실을 감수 하더라도...) - Row Migration이란 Block 하나에 전부 입력할 수 없는 Row를 다른 Block으로 옮겨서 입력하는 것을 말한다.
