Database Copying/Cloning

A database cloning procedure is especially useful for the DBA who wants to give his developers a full-sized TEST and DEV instance by cloning the PROD instance into the development server areas.

This Oracle clone procedure can be use to quickly migrate a system from one UNIX server to another.  It clones the Oracle database and this Oracle cloning procedures is often the fastest way to copy a Oracle database.

STEP 1: On the old system, go into SQL*Plus, sign on as SYSDBA and issue: “alter database backup controlfile to trace”. This will put the create database syntax in the trace file directory. The trace keyword tells oracle to generate a script containing a create controlfile command and store it in the trace directory identified in the user_dump_dest parameter of the init.ora file. It will look something like this:

    STARTUP NOMOUNT

    CREATE CONTROLFILE REUSE DATABASE "OLDLSQ" NORESETLOGS

    NOARCHIVELOG

    MAXLOGFILES 16

    MAXLOGMEMBERS 2

    MAXDATAFILES 240

    MAXINSTANCES 1

    MAXLOGHISTORY 113

    LOGFILE

    GROUP 1 ('/u03/oradata/oldlsq/log1a.dbf',

    '/u03/oradata/olslsq/log1b.dbf') SIZE 30M,

    GROUP 2 ('/u04/oradata/oldlsq/log2a.dbf',

    '/u04/oradata/oldlsq/log2b.dbf') SIZE 30M

    DATAFILE

    '/u01/oradata/oldlsq/system01.dbf',

    '/u01/oradata/oldlsq/mydatabase.dbf'

    ;

    # Recovery is required if any of the datafiles are restored

    # backups, or if the last shutdown was not normal or immediate.

    RECOVER DATABASE

    # Database can now be opened normally.

    ALTER DATABASE OPEN;

 STEP 2: Shutdown the old database

 STEP 3: Copy all data files into the new directories on the new server. You may change the file names if you want, but you must edit the controlfile to reflect the new data files names on the new server.

    rcp /u01/oradata/oldlsq/* newhost:/u01/oradata/newlsq

    rcp /u01/oradata/oldlsq/* newhost:/u01/oradata/newlsq

    rcp /u03/oradata/oldlsq/* newhost:/u03/oradata/newlsq

    rcp /u04/oradata/oldlsq/* newhost:/u04/oradata/newlsq

 STEP 4: Copy and Edit the Control file – Using the output syntax from STEP 1, modify the controlfile creation script by changing the following:

 Old:

     CREATE CONTROLFILE REUSE DATABASE "OLDLSQ" NORESETLOGS

 New:

     CREATE CONTROLFILE SET DATABASE "NEWLSQ" RESETLOGS

 STEP 5: Remove the “recover database” and “alter database open” syntax

    # Recovery is required if any of the datafiles are restored

    # backups, or if the last shutdown was not normal or immediate.

    RECOVER DATABASE

    # Database can now be opened normally.

    ALTER DATABASE OPEN;

STEP 6: Re-names of the data files names that have changed.

Save as db_create_controlfile.sql.

Old:

    DATAFILE

    '/u01/oradata/oldlsq/system01.dbf',

    '/u01/oradata/oldlsq/mydatabase.dbf'

New:

    DATAFILE

    '/u01/oradata/newlsq/system01.dbf',

    '/u01/oradata/newlsq/mydatabase.dbf'

STEP 7: Create the bdump, udump and cdump directories

    cd $DBA/admin

    mkdir newlsq

    cd newlsq

    mkdir bdump

    mkdir udump

    mkdir cdump

    mkdir pfile

 STEP 8: Copy-over the old init.ora file

     rcp $DBA/admin/olslsq/pfile/*.ora newhost:/u01/oracle/admin/newlsq/pfile

 STEP 9: Start the new database

     @db_create_controlfile.sql

 STEP 10: Place the new database in archivelog mode

Database present status

SELECT SYSDATE-logon_time "Days", (SYSDATE-logon_time)*24 "Hours", status
from  sys.v_$session where  sid=1

SELECT DECODE(TRUNC(SYSDATE - LOGON_TIME), 0, NULL, TRUNC(SYSDATE - LOGON_TIME) || ' Days' || ' + ') || TO_CHAR(TO_DATE(TRUNC(MOD(SYSDATE-LOGON_TIME,1) * 86400), 'SSSSS'),'HH24:MI:SS') UPTIME FROM v$session WHERE SID = 1;

ORA-02030 - Grants on v$ views

Today I have faced an issue while giving GRANT permission on a v$ view. Received 'ORA-02030: can only select from fixed tables/views' error.

SQL> grant select on v$session to TEST_SUH;
grant select on v$session to TEST_SUH
                *
ERROR at line 1:
ORA-02030: can only select from fixed tables/views

SQL>

Solution:

Here the problem is caused because of trying to give select privilege on a synonym, Oracle v$ views are named V_$VIEWNAME and they have synonyms in format V$VIEWNAME and we can't give any privilege on a synonym.

If you want to give permission to a V$ views, Follow below way,,

SQL> grant select on v_$session to TEST_SUH;

Grant succeeded.

Delete vs Truncate

Delete Command:

• It is DML command. 
• Command is for deleting the rows from the table.
• Can delete selective rows from the table using where clause.
• All rows can be deleted if no where clause is specified.
• It needs a commit or rollback command to complete the transaction or make it as permanent change.
• Delete will generate redo log entries.
• Delete command use the Undo tablespace to rollback the transaction.
• Delete operation is slow compared to truncate command as it generates redo log entries.
• Delete operation fires the delete triggers on that particular table.
• You can grant delete table privilege to a user.
• Delete never de-allocate the space. It needs a table reorganization to claim the free space.
• Delete doesn’t reset the high watermark.

Truncate Command:

• Truncate is DDL command. Obviously implicit commit is followed by truncate.
• Truncate command removes the entire rows from the table.
• Truncate command cannot be used for selective deletes.
• There is no rollback option with truncate command.
• There will not be any undo generation so this will not use undo tablespace.
• Truncate does not generate redo log entries.
• Truncate is faster compared to delete command.
• Underling triggers will not get fired for truncate command.
• You cannot grant truncate table privilege to a user.
• Truncate de-allocate the space.
• Truncate makes unusable index usable again.
• You cannot flashback truncate command.
• Truncate reset the high watermark.

Data Pump impdp/expdp : Extract DDL and DML from dump file using SQLFILE option

Using data pump IMPDP utility we can generate SQL or DDL/DML from the dump file using SQLFILE option. When you execute IMPDP with SQLFILE option it won’t import the data into the actual tables or into the schema. Suppose if you wanted to generate some particular DDL's from the database you can use this option. Please find the example below with all syntax's.
