Table Compression Enhancement in Oracle Database 11g R2
 
05:00
Table Compression: Overview Oracle Database supports three methods of table compression: 1.Basic table compression 2.OLTP table compression Oracle Corporation recommends to compress all data to reduce storage costs. The Oracle database can use table compression to eliminate duplicate values in a data block. For tables with highly redundant data, compression saves disk space and reduces memory use in the database buffer cache. Table compression is transparent to database applications. The table_compression clause is valid only for heap-organized tables. The COMPRESS keyword enables table compression. The NOCOMPRESS keyword disables table compression. NOCOMPRESS is the default. With basic compression, the Oracle database compresses data at the time of performing bulk load using operations such as direct loads or CREATE TABLE AS SELECT. With COMPRESS FOR OLTP, the Oracle database compresses data during all DML operations on the table.

Held on August 9 2018 This session by Gregg Christman focuses on general questions and insights regarding Oracle Basic Compression, Oracle OLTP Table Compression and Oracle Advanced Row Compression. Here is a quick guide to the highlights: 2:25 Basic vs. Advanced Row Compression comparison 4:55 Should you expect the same compression ratio with Basic and Advanced Row Compression? 8:29 Should you compress all tables and partitions? 15:50 What is the overhead associated with Advanced Row Compression? 17:06 Do I need to change my application to use compression? 17:31 Who uses Advanced Row Compression? 18:35 Is there any ongoing administration with Advanced Row Compression 20:43 When does updated data get compressed? 26:30 What role does PCTFREE play in updates and compression? 28:44 Does Advanced Row Compression work with Oracle Encryption? 29:34 Does enabling compression online or offline make a difference? 31:38 What are the typical compression ratios with Basic and Advanced Row Compression? 32:56 Are there any suggested MOS notes related to compression? 34:12 Feedback about ACO from customers AskTOM Office Hours offers free, monthly training and tips on how to make the most of Oracle Database, from Oracle product managers, developers and evangelists. https://asktom.oracle.com/ Oracle Developers portal: https://developer.oracle.com/ Sign up for an Oracle Cloud trial: https://cloud.oracle.com/en_US/tryit music: bensound.com

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.

When to use Oracle Database Bitmap Indexes Lesson 1
 
00:49
This tutorial will identify some use cases for Oracle bitmap indexes, including some of the more advanced capabilities. See all lessons, free, at http://www.skillbuilders.com/when-to-use-oracle-bitmap-indexes. Indexing your Oracle Database for best performance? There are cases, depending on data structures and queries, where b-tree indexes are not useful (e.g. scan access paths perform inadequately). In these cases, bitmap indexes may be a better solution. Bitmap indexes are a powerful tool, but they need to be used with care. Inappropriate use may cause problems worse than those they solve. The tutorial covers somewhat more advanced cases such as using bitmap join indexes to denormalize a snowflake schema, and to enable star transformations in queries that join fact tables to several dimension tables. This training will benefit any Oracle DBA administering a Data Warehouse or VLDB and "power" developers working in same. Instructor: Oracle Certified Master DBA John Watson, SkillBuilders

How to Compress an ArcSDE geodatabase? lets learn on how to compress an arcsde geodatabase launch arc catalog now point to note is that only an geodatabase administrator can compress the geodatabase so here we will use sde user to compress the gdb as of now we donot have any data in this db but still i can show you how to compress so we can either compress from here and it will be running in the background or we can run the compress tool. . COOL our database is compressed now now you notice that compress log is generated this compress log is generated in the beginning of the compress operation or when the compress operation is done first time on a database every time you compress the database, an entry of compress will be added in this compress log i will show you if the end_state_count is 1, that means the database is compressed to state 0. so it how we can compress its done For more information, write to us at www.arcsdesupport.com or visit arcsde.blogspot.in

Creating Tables Without Segments
 
04:52
Understand Deferred Segment Creation Beginning with Oracle Database 11g Release 2, when you create heap-organized tables in a locally managed tablespace, the database defers table segment creation until the first row is inserted. In addition, segment creation is deferred for any LOB columns of the table, any indexes created implicitly as part of table creation, and any indexes subsequently explicitly created on the table. The advantages of this space allocation method are the following: 1.It saves a significant amount of disk space in applications that create hundreds or thousands of tables upon installation, many of which might never be populated. 2.It reduces application installation time.

How to implement VPD (Virtual Private Database) in Oracle Database(9i,10g,11g,12c) Enterprise Edition. PART 1 Video links: Part 1 https://youtu.be/JVvtvh3cN1I Part 2 https://youtu.be/xLcin_Wgbvs Part 3 https://youtu.be/mE1cSbmEwnQ This is Part of Oracle Advance Security. Please view my earlier videos on how to create a database , if you are not having a database. 1)First we will create the users needed for our environment a)Owner of the schema which will have the objects or tables b)security admin user c)non owner user1 & user2 which will have limited access as per data in the rows (here user1 will have access to data with HR and user2 with FINANCE) Object owner creation: -------------- CREATE USER schemaowner IDENTIFIED BY schemaowner DEFAULT TABLESPACE users TEMPORARY TABLESPACE temp; GRANT connect, resource TO schemaowner; alter user schemaowner quota unlimited on users; security admin user creation: -------------- CREATE USER SEC_ADM IDENTIFIED BY sec_adm default tablespace users temporary tablespace TEMP; GRANT CONNECT, RESOURCE TO sec_adm; alter user sec_adm quota unlimited on users; garnts for the sec_adm user: ------------- GRANT CREATE SESSION,CREATE ANY CONTEXT,CREATE PROCEDURE,CREATE TRIGGER, ADMINISTER DATABASE TRIGGER TO SEC_ADM; GRANT EXECUTE ON DBMS_SESSION TO SEC_ADM; GRANT EXECUTE ON DBMS_RLS TO SEC_ADM; create user with restricted access on table: ----------------------- CREATE USER user1 IDENTIFIED BY user1 DEFAULT TABLESPACE users TEMPORARY TABLESPACE temp; GRANT connect, resource TO user1; CREATE USER user2 IDENTIFIED BY user2 DEFAULT TABLESPACE users TEMPORARY TABLESPACE temp; GRANT connect, resource TO user2; Now we will log in as schemaowner and create one tables : ------------------- CONN schemaowner/schemaowner This table is the table which contains the secure as well as un-restricted data CREATE TABLE user_data (column1 VARCHAR2(50) NOT NULL, user_id VARCHAR2(30) NOT NULL); Now to access this table from other schema we need to give the select and insert privs to: GRANT SELECT, INSERT ON user_data TO sec_adm,user1, user2;

SUBSCRIBE to our Google Earth flights channel - https://www.youtube.com/channel/UC6UuCPh7GrXznZi0Hz2YQnQ Database management systems provide multiple types of indexes to improve performance and data integrity across diverse applications. Index types include b-trees, bitmaps, and r-trees. In database management systems, a reverse key index strategy reverses the key value before entering it in the index. E.g., the value 24538 becomes 83542 in the index. Reversing the key value is particularly useful for indexing data such as sequence numbers, where each new key value is greater than the prior value, i.e., values monotonically increase. Reverse key indexes have become particularly important in high volume transaction processing systems because they reduce contention for index blocks. Reversed key indexes use b-tree structures, but preprocess key values before inserting them. Simplifying, b-trees place similar values on a single index block, e.g., storing 24538 on the same block as 24539. This makes them efficient both for looking up a specific value and for finding values within a range. However if the application inserts values in sequence, each insert must have access to the newest block in the index in order to add the new value. If many users attempt to insert at the same time, they all must write to that block and have to get in line, slowing down the application. This is particularly a problem in clustered databases, which may require the block to be copied from one computer's memory to another's to allow the next user to perform their insert. Reversing the key spreads similar new values across the entire index instead of concentrating them in any one leaf block. This means that 24538 appears on the same block as 14538 while 24539 goes to a different block, eliminating this cause of contention. (Since 14538 would have been created long before 24538, their inserts don't interfere with each other.) Reverse indexes are just as efficient as unreversed indexes for finding specific values, although they aren't helpful for range queries. Range queries are uncommon for artificial values such as sequence numbers. When searching the index, the query processor simply reverses the search target before looking it up. Typically, applications delete data that is older on average before deleting newer data. Thus, data with lower sequence numbers generally go before those with higher values. As time passes, in standard b-trees, index blocks for lower values end up containing few values, with a commensurate increase in unused space, referred to as "rot". Rot not only wastes space, but slows query speeds, because a smaller fraction of a rotten index's blocks fit in memory at any one time. In a b-tree, if 14538 gets deleted, its index space remains empty. In a reverse index, if 14538 goes before 24538 arrives, 24538 can reuse 14538's space.
