Database Point-in-Time Recovery | RMAN INCREMENTAL Backups | DB PITR
 
08:41
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

Oracle Tablespace PITR Recovery | TS-PITR Part - 1
 
09:29
https://dbagenesis.com/p/oracle-advanced-rman-backup-recovery Recovery Manager (RMAN) automatic TSPITR enables you to quickly recover one or more tablespaces in a database to an earlier time without affecting the rest of the tablespaces and objects in the database. RMAN TSPITR is most useful for the following situations: 1. You want to recover a logical database to a point different from the rest of the physical database, when multiple logical databases exist in separate tablespaces of one physical database. For example, you maintain logical databases in the orders and personnel tablespaces. An incorrect batch job or DML statement corrupts the data in only one of the tablespaces. 2. You want to recover data lost after DDL operations that change the structure of tables. You cannot use Flashback Table to rewind a table to before the point of a structural change such as a truncate table operation. 3. You want to recover a table after it has been dropped with the PURGE option. 4. You want to recover from the logical corruption of a table. You can also use Flashback Database to rewind data, but you must rewind the entire database rather than just a subset. Also, unlike TSPITR, the Flashback Database feature necessitates the overhead of maintaining flashback logs. The point in time to which you can flash back the database is more limited than the TSPITR window, which extends back to your earliest recoverable backup.

Can you flashback table into SYSTEM tablespace?
 
10:02
Flashback feature in Oracle database is well known to roll back the table to a specific timestamp (depends on undo retention) or to restore dropped table and many more. We must have used this flashback feature so far on application schema objects and found working without any issues. As an Oracle DBA did you configure any tools (might be monitoring, RMAN catalog or any) with objects created in SYSTEM tablespace? If so, you probably would see some problems later when you need to use Flashback on these objects though they are not Oracle supplied objects. Let us go through a case study which will clearly explain you the functionality of Flashback table. Did you like the video? Subscribe now, Like it and share it.

PRM-DUL untruncate Oracle Tables ,recover truncated oracle table data
 
02:41
Why DUL? Doesn’t need the database or the instance to be open Does not use recovery, archive logs etc… It doesn’t care about data consistency more tolerant to data corruptions Does not require the SYTEM tablespace to recover DUL is a utility that can unload data from “badly damaged” databases. DUL will scan a database file, recognize table header blocks, access extent information, and read all rows Creates a SQL*Loader or Export formatted output matching SQL*Loader control file is also generated If data files are not available for the SYSTEM TableSpace the unload can still continue but USER, TABLE and COLUM names will not be known. Identifying the tables can be an overwhelming task. But it can be (and has been) done. You need in depth knowledge about your application and the application tables. Column types can be guessed by DUL, but table and column names are lost. Any old SYSTEM tablespace from the same database but weeks old can be of great help!. Most of the information that DUL uses does not change. (only the dataobj# is during truncate or index rebuild)

SQL: Delete Vs Truncate Vs Drop
 
08:27
In this tutorial, you'll learn the difference between delete/drop and truncate. PL/SQL (Procedural Language/Structured Query Language) is Oracle Corporation's procedural extension for SQL and the Oracle relational database. PL/SQL is available in Oracle Database (since version 7), TimesTen in-memory database (since version 11.2.1), and IBM DB2 (since version 9.7).[1] Oracle Corporation usually extends PL/SQL functionality with each successive release of the Oracle Database. PL/SQL includes procedural language elements such as conditions and loops. It allows declaration of constants and variables, procedures and functions, types and variables of those types, and triggers. It can handle exceptions (runtime errors). Arrays are supported involving the use of PL/SQL collections. Implementations from version 8 of Oracle Database onwards have included features associated with object-orientation. One can create PL/SQL units such as procedures, functions, packages, types, and triggers, which are stored in the database for reuse by applications that use any of the Oracle Database programmatic interfaces. PL/SQL works analogously to the embedded procedural languages associated with other relational databases. For example, Sybase ASE and Microsoft SQL Server have Transact-SQL, PostgreSQL has PL/pgSQL (which emulates PL/SQL to an extent), and IBM DB2 includes SQL Procedural Language,[2] which conforms to the ISO SQL’s SQL/PSM standard. The designers of PL/SQL modeled its syntax on that of Ada. Both Ada and PL/SQL have Pascal as a common ancestor, and so PL/SQL also resembles Pascal in several aspects. However, the structure of a PL/SQL package does not resemble the basic Object Pascal program structure as implemented by a Borland Delphi or Free Pascal unit. Programmers can define public and private global data-types, constants and static variables in a PL/SQL package.[3] PL/SQL also allows for the definition of classes and instantiating these as objects in PL/SQL code. This resembles usage in object-oriented programming languages like Object Pascal, C++ and Java. PL/SQL refers to a class as an "Abstract Data Type" (ADT) or "User Defined Type" (UDT), and defines it as an Oracle SQL data-type as opposed to a PL/SQL user-defined type, allowing its use in both the Oracle SQL Engine and the Oracle PL/SQL engine. The constructor and methods of an Abstract Data Type are written in PL/SQL. The resulting Abstract Data Type can operate as an object class in PL/SQL. Such objects can also persist as column values in Oracle database tables. PL/SQL is fundamentally distinct from Transact-SQL, despite superficial similarities. Porting code from one to the other usually involves non-trivial work, not only due to the differences in the feature sets of the two languages,[4] but also due to the very significant differences in the way Oracle and SQL Server deal with concurrency and locking. There are software tools available that claim to facilitate porting including Oracle Translation Scratch Editor,[5] CEITON MSSQL/Oracle Compiler [6] and SwisSQL.[7] The StepSqlite product is a PL/SQL compiler for the popular small database SQLite. PL/SQL Program Unit A PL/SQL program unit is one of the following: PL/SQL anonymous block, procedure, function, package specification, package body, trigger, type specification, type body, library. Program units are the PL/SQL source code that is compiled, developed and ultimately executed on the database. The basic unit of a PL/SQL source program is the block, which groups together related declarations and statements. A PL/SQL block is defined by the keywords DECLARE, BEGIN, EXCEPTION, and END. These keywords divide the block into a declarative part, an executable part, and an exception-handling part. The declaration section is optional and may be used to define and initialize constants and variables. If a variable is not initialized then it defaults to NULL value. The optional exception-handling part is used to handle run time errors. Only the executable part is required. A block can have a label. Package Packages are groups of conceptually linked functions, procedures, variables, PL/SQL table and record TYPE statements, constants, cursors etc. The use of packages promotes re-use of code. Packages are composed of the package specification and an optional package body. The specification is the interface to the application; it declares the types, variables, constants, exceptions, cursors, and subprograms available. The body fully defines cursors and subprograms, and so implements the specification. Two advantages of packages are: Modular approach, encapsulation/hiding of business logic, security, performance improvement, re-usability. They support object-oriented programming features like function overloading and encapsulation. Using package variables one can declare session level (scoped) variables, since variables declared in the package specification have a session scope.
