Purging Old Files in Linux
By combining the Linux "find" command with "mtime" and "rm", you can remove files older than a specified number of days. This can be really handy when dealing with incremental backups. Please be careful running a code like this since if it is run in the wrong folder, you could lose some important files. But if following the example correctly, you can maintain a backup folder quite well from a simple cronjob.

SQL: Delete Vs Truncate Vs Drop
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.

How to Detect Soft Corruption in Oracle 12c Database
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.

Delete, Drop, and Truncate Statements in Hive
Delete, Drop, and Truncate Statements in Hive Delete Statement: Delete statement is used to delete certain rows from a table based on a condition specified using the WHERE clause. The syntax is in below as highlighted. DELETE FROM tablename [WHERE expression]; Note: DELETE statement is available from hive 0.14.0 version and above Drop Statement: The drop table statement is used to drop the table altogether. The syntax is highlighted here: DROP TABLE IF EXISTS TABLENAME; Let’s quickly see how the managed table and external table differs when dropping the table. We have already discussed this in the “Two different types of hive tables” video. Take a look at it if you haven’t. For the managed hive tables, the drop table statement removes the metadata information as well as the data. The data will be actually moved to .Trash/Current directory. metadata will be permanently deleted. However for external tables, only the metadata information is permanently deleted and the actual data remains intact in the hdfs directories. So in the case of external table, if the table was deleted accidentally, then the table can be re-created by using the same schema and specifying the same location for the hdfs data directory. If deleting the external table was the intention, then after deleting the table using the drop statement, you may also delete the underlying hdfs data directory by issuing the hdfs dfs -rm command. Truncate Statement: Truncate table statement is used to remove only the data from the table. The table structure with the schema remains intact. Truncate removes all the rows from a table or partition. The syntax is highlighted below. TRUNCATE table syntax TRUNCATE TABLE TABLENAME;

Difference Between Delete and Truncate
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
