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;

This video is a brief introduction on how to create key groups / Indexes in Erwin Data Modeler.It also demonstrates the use of Macros to name the indexes Refer "Template Language and Macro Reference" PDF by ERwin. The following is the Macro I have used in the demo. This macro has additional logic than just get the number from the keytype and add it to our index name, it checks if the number is less than ten, if so it will add a zero in front of it( this calculation is done using the If statements) %Switch(%Substr(%KeyType,1,2)) { %Choose(pk) {x_%tablename_pk} %Choose(ak) {x_%tablename_uk_%if(%==(0,%/(substr(%keyType,3,4),10))) ) {%concat(0,%substr(%keyType,3,4))} %else {%substr(%keyType,3,4)}} %Default {x_%tablename_%if(%==(0,%/(substr(%keyType,3,4),10))) ) {%concat(0,%substr(%keyType,3,4))} %else {%substr(%keyType,3,4)}} }

Oracle Forms 10g: list items poplist, tlist, combobox with user input
 
24:01
List items poplist, tlist, combobox with user input A list item is an interface object that displays a predefined set of choices, each corresponding to a specific data value. You use the list item at run time to select a single value. List choices or elements are mutually exclusive; one and only one can be selected at a time. The Three List Item Styles • Poplist: Appears as a field with an iconic button attached to the right (When you click a poplist, all its list elements are displayed.) • Tlist: Appears as a rectangular box that displays the list elements (When the display area is not big enough to display all the list elements, a scroll bar is automatically attached to the right to view the remaining list elements.) • Combo box: Appears as a field with a down arrow next to its right (Use the button to display all the combo box list elements. The combo box accepts user input.) Uses and Benefits of List Items • Enable display of a defined set of choices • Display a set of choices without using a vast area of canvas • Provide an alternative to radio groups • Provide a Windows-style list of values Follow me: https://www.facebook.com/munir.du Oracle Forms 10g: Oracle Forms building menus Oracle Forms 10g: Controlling Validation Using Properties-Validate from List Oracle Forms 10g: ONETIME _WHERE clause to restrict the query only once Oracle Forms 10g: Forms Calendar in date field Oracle Forms 10g: Image items Oracle Forms 10g: Change list items at run time Oracle Forms 10g: Dynamic list item Oracle Forms 10g: Case-sensitive query and interacting with check box using trigger Oracle Forms 10g: How to create iconic button

Difference Between Delete and Truncate
 
03:41
Below is link for Useful Pl/SQL Books http://goo.gl/XMy0tt ---------------------------------------------------------- Difference Between Delete and Truncate in Detail On bigger picture they serve the same purpose but there are many Differences listed with examples Point Delete Truncate 1. Data Recovery Delete: Come under the DML Category, we need to commit or Rollback explicitly to make the changes permanent, so we can recover the data by Rollback command fully with in a session or up to a point if Save Points are used Fall In DDL Category (DDL Command issue the Auto commit implicitly) so no chances of Recovery even not using the Flashback table method. But Truncate operations are also logged , they didn’t generate redo SQL but they are logged , view for truncated data info V$LOGMNR_CONTENTS 2. Data Removal Delete Can remove all or selected data using the Where Clause predicates. Or we can say delete any subset of rows We can Truncate complete table or a partition or sub partition of a table. 3. Speed Delete is Slower because oracle maintain the redo logs for Read Consistency (so that every session connected can see a consistent data at a given point of time ) Delete is very time consuming activity especially when table have numerous indexes and Triggers associated with table Faster as no data logs are maintained no associated trigger firing. 4. DML Triggers Firing DML (Delete) triggers associated with table will fire. DML Trigger will not fire in case of truncate method. 5. Flashback Technology Data can be recovered even after commit operation using Flashback Table options Flashback_transaction_query table will give what to recover and up to which point. Data cannot be recovered in truncate method by Flashback table option. 6. Referential Integrity Constraint Behavior if we don’t have related data in child table then we can delete the data from the parent table or we have variants like On Delete Cascade & on Delete set Null. We can’t truncate a table with enable Referential Integrity Constraint, even there is no data in the child table, we have to disable or drop the constraint if we want to truncate the table. Exception: Truncate is possible if the FK is self-referential means primary key and foreign key are on the same table. 7. Space De allocation or Space Utilization No extent reset with delete when deleting rows from a table, extents are not de allocated, So if there were 50 extents in the table before the deletion, there will still be 50 after the deletion. Truncate: When a table is truncated it will free the space allocated except in case of reuse storage clause. This space can subsequently be used only by new data in the table or cluster resulting from insert or update operations .All extents are de allocated leaving only the extents specified when the table was originally created .Example So if the table was originally created with min extents 3, there will be 3 extents remaining when the tables is truncated. When you truncate a table, NEXT is automatically reset to the last extent deleted. 8. High Water Mark Delete will not reset the high water mark Truncate will reset the High Water mark which is very important for performance point of view as in case of full table scan and full index scan oracle will read all the block under high water mark this makes a lot of difference in terms of performance. 9. Cluster No as such restriction with delete. You cannot individually truncate a table that is part of a cluster. You must truncate the cluster, Delete all rows from the table, or drop and re-create the table. 10. Information Capturing Delete : we can capture the row information what we have deleted using Delete Method, f you are deleting multiple records then use composite data types (collections & records) Truncate Don’t have this feature of capturing the deleted records. 11. Function Based Index Impact DELETE You cannot delete rows from a table if a function-based index on the table has become invalid. You must first validate the function-based index. Truncate: No as such restriction 12. UNUSABLE Indexes Delete no as such feature. Truncate if table is not empty then truncate make all unusable indexes to useable. 13. Complex views You cannot delete data from a Complex view except through INSTEAD OF triggers. But we can delete data from simple Views and MV. We cannot truncate a view simple or complex but you can truncate MV with special Features like Preserve MV Logs and Purge MV Logs. 14. Privileges Delete You need to provide delete table privilege on object. Truncate you must have drop table privilege there is no truncate table privilege exists. 15. Domain Index No as such restriction You cannot truncate the object having domain index in invalid or In progress state

Oracle SQL Tutorial 22 - Why Primary Keys Shouldn't Change
 
07:14
In the last video I mentioned that with our database design it is important to make sure that nobody tries to update a user's username. What happens if they do? Nothing horrible, Oracle will just throw an error. That's not such a big deal, but if you are hoping to make some kind of application that allows someone to change their username, this is not the best set up. Why? If you look at the projects table, we have a foreign key that references the username. Let's assume for a moment that Oracle allows you to do anything with your data. That means that if a user updates their username, there will be projects created by users that don't exist. Or a user could change their name to the previous owner. To fix this problem, we would need something such as an ON UPDATE CASCADE command for our foreign key. That would mean that if the user updated their username, the columns that reference that username would also update to the new value. This exists in some database management systems, but this does not exist in Oracle at the time of this video. How do we get around this problem? I'm sure we could conjure up something to allow us to update the username, but the easiest solution is to reference the user_id instead of the username. That way, when the username is updated, nothing changes inside of the foreign key. As a general rule, primary keys should never change. Foreign keys CAN change, but they should not change because a primary key changed. So, if we did happen to use a username as a column, it would be frowned upon if the username had to change because the column it references changes. However, it would be acceptable to change the foreign key if we needed to point to a new entity in the users table. Even if a username is never intended to change, these complications bother a lot of people. You can mitigate these problems by only referencing surrogate keys in foreign keys. This has the downside though that when you retrieve the data, you are going to have to do more work to make the data readable. For example, we had a table that was called project_users. It is essentially a table that says what users are part of what projects. We could have the foreign keys reference the project's name and the user's username. Then when you could say SELECT * FROM project_users. The data would be completely readable without doing anything. If you switch to only referencing surrogate primary keys, you will have a bunch of random numbers that don't mean anything and will have to be joined with other tables…which is really super frustrating when later you have to join a thousand tables to read anything. Which side do you prefer? Pick a side. Choose wisely.

How to implement strong password verify function on Oracle database
 
03:36
Establishing and enforcing limitations on password complexity, expiration, lockout, and reuse will reduce the risk that threat agents may gain access by exploiting a weakness in these settings. Create a strong password verify function and attach the function to default or custom profile which will be assigned to all user accounts created in the database. Following values are recommended for the password profile options:- failed_login_attempts=10- password_life_time=90- password_reuse_max=20- password_reuse_time=365- password_lock_time=1- password_grace_time=3
