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.

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.

Oracle Managed Files
 
11:12
Oracle Managed Files (OMF) OMF simplifies the creation of databases as Oracle does all OS operations and file naming. It has several advantages including: * Automatic cleanup of the filesystem when database objects are dropped. * Standardized naming of database files. * Increased portability since file specifications are not needed. * Simplified creation of test systems on differing operating systems. * No unused files wasting disk space. The location of database files is defined using the DB_CREATE_FILE_DEST parameter. If it is defined on its own all files are placed in the same location. If the DB_CREATE_ONLINE_LOG_DEST_n parameter is defined alternate locations and levels of multiplexing can be defined for Logfiles. These parameters are dymanic and can be changed using the ALTER SYSTEM statement. https://www.facebook.com/photo.php?v=675154272533058&set=vb.244092622305894&type=2&theater&notif_t=video_comment

Performing Oracle 11g ASM Data Migration
 
17:34
Performing Oracle 11g Automatic Storage Management - ASM Data Migration Purpose of ASM Data Migration Alternatives to ASM storage include file systems, raw disks, and SAN configurations. ASM includes a number of benefits over these storage alternatives, including performance optimization, redundancy protection, and load balancing. You do not need to obtain a third-party Logical Volume Manager because ASM manages disks for you. Oracle Real Application Clusters (Oracle RAC) databases benefit from ASM because it provides ready-made shared storage. If a database currently uses a storage system other than ASM, then you can migrate all or part of the database into ASM, thereby simplifying database administration. You can also migrate a flash recovery area to ASM. Native operating system commands such as Linux cp or Windows COPY cannot write or read files in ASM storage. Because RMAN can read and write ASM files, you can use RMAN to copy datafiles into and out of ASM storage or between ASM disk groups. This technique is useful if you need to store backups on user-managed disks.

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.

SAP ASE 16 Learning Part 9 Enabling Auto Expansion in Sybase ASE 16. To Learn or Teach Linux visit www.theskillpedia.com, A Marketplace for Learners and Trainers. Session 9 Auto Expansion Ram N Sangwan Auto Expand Feature We can configure databases to expand automatically when they run out of space. This automatic expansion process runs as a background task and generates informational messages in the server's error log. By default Sybase does not have this turned on, as a matter of fact, you have to run a script that is shipped with the product in order to create the stored procedures that will make it possible for you to use this feature. Auto Expand Contd.. Use following steps to set up a database for automatic expansion. Please log in with sa_role permission. Install automatic database expansion procedures. Installdbextend script installs the family of threshold action procedures and sp_dbextend in the sybsystemprocs database. Expanding Databases Automatically You can configure databases to expand automatically when they run out of space. The stored procedure sp_dbextend allows you to install thresholds that identify those devices with available space, and then appropriately alter the database—and the segment where the threshold was fired—on these devices. Automatic Expansion – How it Works After you set up a database for automatic expansion, internal mechanisms fire when a database grows to its free space threshold, and increase the size of the database by the amount of space your expansion policies specify. The automatic expansion process measures the amount of room left on all devices bound to the database. If there is sufficient room on the devices, the database continues to grow. By default, if the size of the device is greater than 40MB, the size of the database is increased by 10 percent. How it Works If your database is smaller than 40MB, the size of the database is increased by 4MB. However, you can specify database resizing limits that match the needs of your site. If any devices are configured for expansion, those devices expand next. Finally, the database is expanded on those devices. Running sp_dbextend Validating current thresholds sp_dbextend includes a powerful simulation mode that any user with sa_role permission can use to simulate the execution of the top-level threshold action procedure Defining Expansion Policies To define expansion policies for the logsegment in the pubs2 database: sp_dbextend ’set’, ’database’, pubs2, logsegment,’3M’ sp_dbextend ’set’, ’threshold’, pubs2, logsegment, ’1M’ To simulate expansion for these policies: sp_dbextend ’simulate’, pubs2, logsegment Example The following examples show the series of database and disk expansions that would occur if the threshold on database pubs2 segment logsegment fired once: sp_dbextend 'simulate', pubs2, logsegment --------------- NO REAL WORK WILL BE DONE. Actual Implementation To actually expand the database manually for this threshold, issue: sp_dbextend 'execute', 'pubs2','logsegment', '1' Manual Expansion To expand the database manually for this threshold, execute: sp_dbextend ’execute’, ’pubs2’, ’logsegment’ Thank You

Setting Up Your Automated Email Marketing for Cleaning Services
 
21:31
Learn how to automate your marketing for cleaning services. Today today Mike coaches Peter Boland, return guest and owner of Oracle Building Maintenance! First things first, avoid overwhelm and start small. It's better to have something in place sooner that works than taking months getting something complex in place. Let’s break down 3 key points to marketing for cleaning services: Know who your customers are and what they want Have a trained sales force in place Automate and supercharge the process already in place with email marketing, funnel marketing, or automated marketing! KEY POINT: Get control of how your commercial cleaning business acquires emails and how you use them Oracle Building Maintenance acquires emails from purchased lists. They then start cold calling individuals to establish a relationship prior to emailing. Over time, when customers need services, they will think of Oracle first because he’s already established a relationship. KEY POINT: Customers will buy when they are ready! Not when you want to sell Make sure you have systems in place that are automated to keep track of everything so that when customers are ready…so are you! For the most successful email marketing plans: Be aware of the stage your customers are In! New clients: Emailing is more aggressive (daily) and then there’s a weaning off Clients that show least amount of interest-touch base about every five weeks KEY POINT: Segment your messaging for maximum effect Segmenting your emails for each customer is imperative. What is segmenting? Just think: Different email messages for each client. For Example: In the commercial cleaning business, if you have four or five different verticals you need to deal with each one of those as a different situation. A medical facility needs will be different from what your customer at a car dealership will want and those needs will then vary for your consumer at a warehouse. 2 Key points to Segmentation: Niche and Interview Pick a niche Interview them to understand who they are and what their “pain” is. Know where they are in the sales cycle Prospective client who just showed interest will have a different message and frequency than existing clients or clients who just quit. RESOURCE ALERT: Check out this in depth article on email marketing SIDE NOTE ON LEAD MAGNETS HERE: While we are on the subject, let’s chat about these lead magnets really quickly! Various lead magnets get different responses from different people. The emails here will vary dependent upon issues and lead magnets. RESOURCE ALERT: Want to know more about commercial cleaning company leads? Check out this podcast http://www.growmycleaningcompany.com/cleaning-company-leads/ KEY POINT: Timing is EVERYTHING! Let’s chat about how many emails a commercial cleaning business should put out in order to keep customers engaged. How much is too much? Let’s break it all down for you in terms of this timing factor: Be aggressive at the beginning, then peel off. At the end of every month, everyone ends up in the same, final email funnel! This is an email that you “ping” customers with at least once a month. This is a generic email to keep contact going between you and your customers. Find the Frequency! In terms of frequency—as long as you're bringing value and interest to the clients, it won’t be a problem. Keep in mind, “filler” emails won’t “fly” with customers. Fewer emails that are higher in quality and content are better than just every day “fluff” or “filler”. What is Considered a “Valuable” Email? Get a “consumer pulse” by checking on the engagement of your customers! If you’re getting lots of clicks, response, shares, and buzz this tells you that your customers find the information valuable! If it’s “dead” like radio silence…you probably have not hit a nerve! How to Engage and get a “Pulse” on What’s Valuable from your Customers: Speak to your customers! Involve them! Send an email stating that you’re posting a survey to discover what they would like to hear more of in their emails! Tell clients that you will reveal the answers from the survey of all customers involved. Surveys can be serious in nature or humorous from time to time! Mix them up!

01 Overview of table Partition in oracle
 
07:26
Partitioning enhances the performance, manageability, and availability of a wide variety of applications and helps reduce the total cost of ownership for storing large amounts of data. Partitioning allows tables, indexes, and index-organized tables to be subdivided into smaller pieces, enabling these database objects to be managed and accessed at a finer level of granularity. Oracle provides a rich variety of partitioning strategies and extensions to address every business requirement. Moreover, since it is entirely transparent, partitioning can be applied to almost any application without the need for potentially expensive and time consuming application changes. Partitioning allows a table, index, or index-organized table to be subdivided into smaller pieces, where each piece of such a database object is called a partition. Each partition has its own name, and may optionally have its own storage characteristics. From the perspective of a database administrator, a partitioned object has multiple pieces that can be managed either collectively or individually. This gives the administrator considerable flexibility in managing partitioned objects. However, from the perspective of the application, a partitioned table is identical to a non-partitioned table; no modifications are necessary when accessing a partitioned table using SQL queries and DML statements. Partitioning Key ======================== Each row in a partitioned table is unambiguously assigned to a single partition. The partitioning key is comprised of one or more columns that determine the partition where each row will be stored. Oracle automatically directs insert, update, and delete operations to the appropriate partition through the use of the partitioning key. When to Partition a Table ========================== Here are some suggestions for when to partition a table: Tables greater than 2 GB should always be considered as candidates for partitioning. Tables containing historical data, in which new data is added into the newest partition. A typical example is a historical table where only the current month's data is updatable and the other 11 months are read only. When the contents of a table need to be distributed across different types of storage devices. When to Partition an Index ============================= Here are some suggestions for when to consider partitioning an index: Avoid rebuilding the entire index when data is removed. Perform maintenance on parts of the data without invalidating the entire index. Reduce the impact of index skew caused by an index on a column with a monotonically increasing value. Partitioned Index-Organized Tables =================================== Partitioned index-organized tables are very useful for providing improved performance, manageability, and availability for index-organized tables. For partitioning an index-organized table: ============================================ Partition columns must be a subset of the primary key columns Secondary indexes can be partitioned (both locally and globally) OVERFLOW data segments are always equi-partitioned with the table partitions See Also: Oracle Database Concepts for more information about index-organized tables System Partitioning System partitioning enables application-controlled partitioning without having the database controlling the data placement. The database simply provides the ability to break down a table into partitions without knowing what the individual partitions are going to be used for. All aspects of partitioning have to be controlled by the application. For example, an insertion into a system partitioned table without the explicit specification of a partition will fail. System partitioning provides the well-known benefits of partitioning (scalability, availability, and manageability), but the partitioning and actual data placement are controlled by the application. See Also: Oracle Database Data Cartridge Developer's Guide for more information about system partitioning Partitioning for Information Lifecycle Management Information Lifecycle Management (ILM) is concerned with managing data during its lifetime. Partitioning plays a key role in ILM because it enables groups of data (that is, partitions) to be distributed across different types of storage devices and managed individually.

How to Detect Soft Corruption in Oracle 12c Database
 
18:19
Detection of Soft Corruption in 12c: To use the scripts below replace : , ",# and $ by proper bracket Lets Create a tablespace and small table. SQL: create tablespace DEMO1 datafile '/u02/tstdb1/TSTDB1/datafile/demo01.dbf' size 50M SQL: create table objects tablespace DEMO1 as select * from dba_objects; SQL: alter table objects add constraint pk_obj primary key #object_id$; SQL: create index idx_obj_name on objects#object_name$ tablespace demo1; Backup tablespace. 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;
