how many bytes take by varchar2 data type in oracle to store number or string values.

When we define varchar2 data type to particular column in table, same time we define its length or you can say its range but knowledge point is how many byte oracle server take? to store particular string or number values its depend upon the character set .So my this post explain to you  how many byte oracle server take to store values.

Explanation:-
                  
SQL> create table test(id varchar2(10);

     table created

SQL> insert into test values('abcdefghij');

    one row inserted

SQL>commit;

SQL> select length ('abcdefghij') from dual;   **/ length is 10 so no error  has been generated after execution of insert statement /*****

SQL> insert into test values('1234567891');
   
         one row inserted

SQL> commit;

SQL> select length('1234567891') from dual;      **/ length is 10 so no error  has been generated after execution of insert statement /*****

LENGTH('1234567891')
--------------------
                  10

SQL>insert into test values('12345678910');

ERROR at line 1:
ORA-12899: value too large for column "SCOTT"."TEST"."ID" (actual: 11, maximum:
10)
             **/ After execution of statement oracle server gives error  because insert statement cross specified range /***

NOTE:- that's means oracle server allowed you to insert only number of numeric and string values as per you specified range of column while creation of table.


SQL>  create table test1 (id VARCHAR2(10 byte));

Table created.

note:- now oracle server take only10byte data that means insert only those numeric and string values which within 10 bytes.if numeric or string values cross 10 byte range then oracle server gives error.

how to kill process which is running on particular session.

Some time we needs to terminate current process which is running on particular users session.in this process first we find out which process is running on particular session then we first get it id and serial number,through this two attribute we can kill the oracle process.

note:- this process is very important to kill oracle process without any impact.

 Oracle session process kill steps:-


SQL>SET LINESIZE 100
COLUMN spid FORMAT A10
COLUMN username FORMAT A10
COLUMN program FORMAT A45

SELECT s.inst_id,
       s.sid,
       s.serial#,
       p.spid,
       s.username,
       s.program
FROM   gv$session s
       JOIN gv$process p ON p.addr = s.paddr AND p.inst_id = s.inst_id
WHERE  s.type != 'BACKGROUND';

SQL> ALTER SYSTEM KILL SESSION 'sid,serial#';

In a RAC environment, you optionally specify the INST_ID, shown when querying the GV$SESSION view. This allows you to kill a session on different RAC node.

SQL> ALTER SYSTEM KILL SESSION 'sid,serial#,@inst_id';


The KILL SESSION command doesn't actually kill the session. It merely asks the session to kill itself. In some situations, like waiting for a reply
from a remote database or rolling back transactions, the session will not kill itself immediately and will wait for the current operation to complete.
In these cases the session will have a status of "marked for kill". It will then be killed as soon as possible.

SQL> ALTER SYSTEM KILL SESSION 'sid,serial#' IMMEDIATE;

Create database link using host:port/service new syntax

when  we want to access data from different database that time we use database link through service name to access particular  data.so my this post is for to create database link without change in to tnsname.ora file that means without using service name.

Example:-
                 Targate Database: orcl
                 Source Database :  test

1)target database
    SQL>create user test
              identified by test
              default tablespace test;
  SQL>grant connect,resource to test;
        
  SQL> connect scott/tiger;

  SQL>  create table test(id number);

SQL>begin
                for i in 1..10 loop
        insert into test values(i);
       end loop;
      end;
/
SQL> commit;

SQL> select count(*) from test;

  COUNT(*)

2)Source Database

SQL> CREATE DATABASE LINK test_db_link
    CONNECT TO scott IDENTIFIED BY tiger

Secure externel password storage using oracle Wallet.

ORACLE WALLET:    Secure external password storage using oracle Wallet.

     Some time we create shell scripts or batch file etc. for database operation.In particulate file we specify the oracle user name and password so it will not secure that means any person can get our username and password through this file. So nullify this problem oracle provide  the solution called as oracle wallet. Using this you can directly connect to oracle server using service name example: '/@db11g'  no need to specify username and password. So no one can get your oracle user password.   

:- ORACLE wallet creation steps.

Note:- every username should have different  service name. so service name cant be conflict for username and his password.

Transfer particulate single table from one database to other database.

   
Transfer particular single table from one database to other database.
 Some time requirement is to transfer only one table to other database for development operation or any operation so that time impdp/expdp logical backup utility helps us to transfer table from one database to other database.so my bellow example showing you transfer one table using expdp/impdp.

Example:-

          Target database:- orcl
          Source database:- db11g

 NOTE:- In step 1 i created tablespace and users its not mandatory. i did this because only after you import data from dump file so after that you just  check it, both tablespace and users created on source database that means you import database process is successfully completed.

tablespace point in time recovery using SCN (RMAN)

tablespace point in time recovery using SCN (RMAN).

  I got this solution after visit number links regarding  rman backup and recovery.I sort all documents and perform this practical on test database and got desired result.

how to create sql profile manually

After going through number Documents regarding sql profile. i got some solution regarding  how to create sql profile manually. so below is example shows details of creation of sql profile.


1) Session I (connect normal user i used scott user).

SQL> create table test (id number );
Table created.

SQL> declare
          begin
           for i in 1 .. 10000 loop
               insert into test values(i);
               commit;
           end loop;
          end;
/
PL/SQL procedure successfully completed.

SQL> create index test_idx on test(id);
Index created.

SQL> exec dbms_stats.gather_table_stats('','TEST');

PL/SQL procedure successfully completed.

sql>set autotrace on

sql>select /*+ no_index(test test_idx) */ * from test where id=1;


Plan hash value: 1357081020


--------------------------------------------------------------------------
| Id  | Operation         | Name | Rows  | Bytes | Cost (%CPU)| Time     |
--------------------------------------------------------------------------
|   0 | SELECT STATEMENT  |      |     1 |     4 |     7   (0)| 00:00:01 |
|*  1 |  TABLE ACCESS FULL| TEST |     1 |     4 |     7   (0)| 00:00:01 |
--------------------------------------------------------------------------

Predicate Information (identified by operation id):
---------------------------------------------------

   1 - filter("N"=1)

2) Session II (connect as sysdba).

Create and execute tuning task and run report tuning task.
Accept recommended SQL Profile.

sql>declare
  my_task_name VARCHAR2(30);
  my_sqltext CLOB;
  begin
     my_sqltext := 'select /*+ no_index(test test_idx) */ * from test where id=1';
     my_task_name := DBMS_SQLTUNE.CREATE_TUNING_TASK(
     sql_text => my_sqltext,
     user_name => 'SCOTT',
     scope => 'COMPREHENSIVE',
     time_limit => 60,
     task_name => 'my_sql_tuning_task_2',
     description => 'Task to tune a query on a specified table');
end;

FINDINGS SECTION (1 finding)
-------------------------------------------------------------------------------

1- SQL Profile Finding (see explain plans section below)
--------------------------------------------------------
  A potentially better execution plan was found for this statement.

  Recommendation (estimated benefit: 95%)
  ---------------------------------------

  - Consider accepting the recommended SQL profile.
    execute dbms_sqltune.accept_sql_profile(task_name =>
            'my_sql_tuning_task_2', task_owner => 'SCOTT', replace => TRUE);

  Validation results
  ------------------
  The SQL profile was tested by executing both its plan and the original plan
  and measuring their respective execution statistics. A plan may have been
  only partially executed if the other could be run to completion in less time.

                           Original Plan  With SQL Profile  % Improved
                           -------------  ----------------  ----------
  Completion Status:            COMPLETE          COMPLETE

  Elapsed Time(us):                 600                40      93.33 %
  CPU Time(us):                     399                 0        100 %
  User I/O Time(us):                  0                 0
  Buffer Gets:                       20                 1         95 %
  Physical Read Requests:             0                 0
  Physical Write Requests:            0                 0
  Physical Read Bytes:                0                 0
  Physical Write Bytes:               0                 0
  Rows Processed:                     1                 1
  Fetches:                            1                 1
  Executions:                         1                 1

  Notes

  -----
  1. The original plan was first executed to warm the buffer cache.
  2. Statistics for original plan were averaged over next 9 executions.
  3. The SQL profile plan was first executed to warm the buffer cache.
  4. Statistics for the SQL profile plan were averaged over next 9 executions.
