Restore points and related data protection features enable us to rewind data back in time to correct any problems caused by logical data corruption or user errors within a designated time window. These features provide a more efficient alternative to point-in-time recovery and does not require a backup of the database to be restored first. The effects are similar to database point-in-time recovery (DBPITR). Restore points is not only effective in traditional database recovery situations but can also be useful during database upgrades, application deployments and testing scenarios when test databases must be quickly created and re-created. Restore points provide capabilities related to Flashback Database and other media recovery operations. In particular, a guaranteed restore point created at a system change number (SCN) ensures that you can use Flashback Database to rewind the database to this SCN. You can use restore points and Flashback Database independently or together

This video gives a quick demonstration of the table point in time (PITR) in Oracle Database 12c. Note. In this case it would be easier to do a flashback query to get the data as it was, but I'm using this simple example to demonstrate this functionality.

Note: this will only work if you have Windows backup or system restore point created! Steps: start Windows Explorer, find the file you want to restore (or choose the drive), right click on it, left click on "Restore previous versions", select versions and check your files by clicking on "Open", if you have found the required version, click on "Restore" or you can just manually copy over the files from the backup. Footage shows how to restore previous version of one specific file.

Database point-in-time recovery (DBPITR) restores the database from backups prior to the target time for recovery, then uses incremental backups and redo to roll the database forward to the target time. DBPITR is sometimes called incomplete recovery because it does not use all of the available redo or completely recover all changes to your database. The target SCN can be specified using a date and time, in which case the operation is sometimes called time-based recovery. https://dbagenesis.com/p/oracle-advanced-rman-backup-recovery

Remove Junk Files to Cleanup Your Windows 10 Computer Firstly, let’s delete the Windows update data. To do that, open C drive, then Windows, then Software Distribution and here choose Download. We have around 1 gig of Windows update data and we don’t need it. If the system needs any file, it will be downloaded again. So no issues. Let me delete everything here in this downloads folder to remove junk files to cleanup the Windows 10 computer. So now the second one. Let’s delete the temporary & prefetch files. To do that, open Run by right-clicking on the #Windows icon and here choose ‘Run’. In here type %temp% and choose ok. Now you will see all the temporary files and delete them all by saving any of the work that you are currently doing with any of the applications. Again open Run by right-clicking on the Windows icon and now just type temp. This is another location where the temp files are stored. Just, delete them all to clean up the temp location. Now we’re going to delete the prefetch files. To do that, open Run dialogue box by typing Windows + R keys together and type prefetch. Select all the files and folders here then proceed to delete them. This is how you remove junk files to clean up your #Windows10 computer. Now, the third one. If you have any issues with the Windows store then just do this thing without changing account settings or deleting installed apps. By opening the Run dialogue box, type wsreset and hit ok. Now you will see the command prompt with a blank screen. You need to wait for a few seconds to complete the reset process. Once done, you will get the Windows store on the console. The fourth one is clearing the browsing history of #Microsoft edge and chrome as I have them. You can try clearing the browsing history of all the browsers that you have. So, now going with Edge browser, Open it and choose these three dots right here and choose settings. Now at the center, click on ‘Choose what to clear’ under ‘clear browsing data’. Tick what you want to delete and choose ‘clear’. Alternatively, you can opt to ‘Always clear this when I close the browser’ option if you wish to clear browsing data regularly to remove junk files to cleanup your windows 10 computer. If you are using #Chrome browser, do these steps to delete the browsing history. Open chrome and choose these three dots to expand the available options. From the menu, choose ‘More Tools’ then ‘Clear browsing data’. You will get a window with basic options. Navigate to the ‘Advanced’ tab and choose the time range, what things you would like to clear etc and click on ‘clear data’. That’s it. The fifth one is to clear the DNS cache. If you have any internet connectivity issues you can run this command to flush the DNS cache. To do that, search for cmd and right click on it to run the command prompt as an administrator. Now here type the following command. ipconfig/flushdns and it will instantly clear the DNS cache for you. The sixth one is to clean up the disk. To do this search for Disk cleanup and open it. Choose the disk you would like to clean up and here I’m choosing the C drive. Now choose the files that you would like to clean up and select ok. It will then clean up the junk files that are in C drive. The seventh one is to free up the space using a restore point. To do that, search for restore point and then open it. Once you have the system restore point window, choose the C drive and choose ‘configure’ to look for the space that was occupied at restore point. Now I have around 2 gigs here and you just need to delete it by choosing delete and press ok. Now create a new restore point and name it as you like. I’m here naming it as restore and it will take less space now. This is how you can remove cache or junk files to cleanup your Windows 10 computer manually without using any software.

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 Flashback Technology is a group of Oracle Database features that let you view past states of database objects or to return database objects to a previous state without using point-in-time media recovery. Oracle Flashback Version Query Use this feature to retrieve metadata and historical data for a specific time interval (for example, to view all the rows of a table that ever existed during a given time interval). Metadata for each row version includes start and end time, type of change operation, and identity of the transaction that created the row version. To create an Oracle Flashback Version Query, use the VERSIONS BETWEEN clause of the SELECT statement. Oracle Flashback Table Use this feature to restore a table to its state at a previous point in time. You can restore a table while the database is on line, undoing changes to only the specified table.
