CLONING OF DATABASE BY RMAN

                                             CLONING OF DATABASE BY RMAN

1) PRIMIARYDATABASE NAME: PROD (172.16.1.145)
2) DUPLICATEDATABASE NAME: DUP (172.16.1.142)

------------------------------------------------------------------------------------------------------------

STEPS1: CONFIGURE THE TNSNAMES.ORA IN PRIMARY:
TO_DUP =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 172.16.1.142)(PORT = 1521))
)
(CONNECT_DATA =
(SERVICE_NAME = dup)
)
)

------------------------------------------------------------------------------------------------------------

STEPS2: CONFIGURE THE LISTNER.ORA IN TARGET SIDE:
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = dup)
(ORACLE_HOME = /oracle/app/oracle/product/10.2.0)
)
)
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = RHEL)(PORT = 1521))
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC0))
)
)

------------------------------------------------------------------------------------------------------------

STEP3 : create password file in duplicate database side
$] $ORACLE_HOME/dbs/orapwd file=orapwdup password=oracle123 entries=5 force=y

------------------------------------------------------------------------------------------------------------

STEP4: COPY intiprod.ora from primary to standby database.
Dbs]$ Scp initprod.ora 172.16.1.142:$ORACLE_HOME/dbs

------------------------------------------------------------------------------------------------------------

STEP5: rename the initprod to initdup.ora in duplicate database.
Dbs]$ mv initprod.ora initdup.ora

------------------------------------------------------------------------------------------------------------

STEP 6: create new folder in primary as well as duplicate databases.
]$ Mkdir /oracle/backup_file

------------------------------------------------------------------------------------------------------------

SETP7: ASSIGN THE LOCATION OF BACKUP FILE IN RMAN PARAMETER AND ALSO CHANGE
CONTROLFILE AUTO BACKUP TO ON
RMAN> CONFIGURE CHANNEL DEVICE TYPE DISK FORMAT '/oracle/backup_files/prod_backup_%U';
RMAN>CONFIGURE CONTROLFILE AUTOBACKUP ON;

------------------------------------------------------------------------------------------------------------

STEP8: create the required folders according the initdup.ora file

------------------------------------------------------------------------------------------------------------

STEP9:
Include db_file_name_convert and log_file_name_convert parameters in initdup .ora file to avoid
the duplication of data files.
Db_file_name_convert=(‘/oracle/app/oracle/oradata/prod’,’/oracle/app/oracle/oradata/dup’)
Log_file_name_convert=(‘/oracle/app/oracle/oradata/prod’,’/oracle/app/oracle/oradata/dup’)

------------------------------------------------------------------------------------------------------------

STEP10: start the duplicate database in nomount stage
SQL> startup nomount
ORACLE instance started.
Total System Global Area 377487360 bytes
Fixed Size 1219520 bytes
Variable Size 113247296 bytes
Database Buffers 260046848 bytes
Redo Buffers 2973696 bytes

------------------------------------------------------------------------------------------------------------

SETP11: GO TO PRIMARY DATABASE TAKE THE BACKUP OF PRIMARY DATABASE
RMAN> BACKUP DATABAE PLUS ARCHIVELOG

------------------------------------------------------------------------------------------------------------

SETP12: THIS BACKUP WILL STORE IN FILE /ORACLE/BACKUP_FILES FOLDER OF PRIMARY DATABASE.

------------------------------------------------------------------------------------------------------------

STEP13: COPT THIS BACKUP TO THE DUPLICATE DATABASE IN THE LOCATION
/ORACLE/BACKUP_FILES:
/ORACLE/BACKUP_FILE$] SCP * 172.16.1.142:/ORCALE/BACKUP_FILES

------------------------------------------------------------------------------------------------------------

STEP 14: NOW GO TO RMAN IN PRIMARY SIDE
$] RMAN TARGET /
STEP 15: GIVE THE AUXILIARY COMMAND SO THAT IT CONNECT DUPLICATE DATABASE
RMAN> connect auxiliary sys/oracle123@to_dup

------------------------------------------------------------------------------------------------------------

STEP16: give the duplicate command so the all the primary database data will transfer to duplicate
database remotely.
Rman>Duplicate target database to ‘dup’;

------------------------------------------------------------------------------------------------------------

duplicate target DATABASE TO ‘dup’;

Job "CLEPROD"."SYS_IMPORT_SCHEMA_01" completed with 6 error(s) at 08:39:47

All the above error ORA-30082 is a warning . This error occurs due to improper or re-order the sequence of importing the objects or due to the dependency on others objects . For example  , in above case data pump import create procedures before views, if our procedure have dependency on views then we will have the ORA-39082 compilation errors . There are various ways to solve these issues. 

1.)              Run  utlrp.sql  to recompile all invalid objects within the database after the import is complete. This script is in the $ORACLE_HOME\rdbms\admin  directory or alternatively we can use the built-in  DBMS_RECOMP package . This will usually clean up all the invalid objects. utlrp.sql  will compile objects in the database across schemas. In case of  Re-mapping objects from one schema to another and utlrp.sql  won't be able to compile them .

2.)               After the import is completed, recompile the every errors . This is useful when you have few errors. The below command are used to recompile the objects as 

3.)              SQL> ALTER PACKAGE <SchemaName>.<PackageName> COMPILE;

4.)              SQL> ALTER PACKAGE <SchemaName>.<PackageName> COMPILE BODY;

5.)              SQL> ALTER PROCEDURE my_procedure COMPILE;

6.)              SQL> ALTER FUNCTION my_function COMPILE;

7.)              SQL> ALTER TRIGGER my_trigger COMPILE;

8.)              SQL> ALTER VIEW my_view COMPILE;

9.)              SQL> EXEC DBMS_UTILITY.compile_schema(schema => 'cleprod')

10.)         SQL> EXEC UTL_RECOMP.recomp_serial('cleprod') ;

ORA-01919:

ORA-01919:

This example, tested on Oracle 10g , demonstrates the ORA-01919 error message, which some people find misleading. First create a user called ANAND, a role called newrole and another user called ANOTHER_USER

SQL> conn / as sysdba

Connected.

SQL> grant create session to anand

  2  identified by anand

  3  /

Grant succeeded.

SQL> create role newrole

  2  /

Role created.

SQL> create user another_user

  2  identified by another_user

  3  /

User created.

SQL>

Connect as ANAND then try to grant role NEWROLE to ANOTHER_USER. This fails but the error message is not helpful. Role NEWROLE  does exist but it has not been granted to ANAND yet:

SQL> conn anand/anand

Connected.

SQL> grant NEWROLE to another_user

  2  /

grant newrole to another_user

*

ERROR at line 1:

ORA-01919: role 'newrole' does not exist

SQL>

Grant the role NEWROLE to ANAND:

SQL> conn / as sysdba

Connected.

SQL> grant newrole to anand

  2  /

Grant succeeded.

SQL>

Then login as ANAND and try to grant NEWROLE to ANOTHER_USER again. This time the error message gives a better explanation:

SQL> conn anand/anand

Connected.

SQL> grant newrole to another_user

  2  /

grant blah to another_user

*

ERROR at line 1:

ORA-01932: ADMIN option not granted for role 'NEWROLE’

SQL>

Now grant the role to ANAND with the ADMIN option:

SQL> conn / as sysdba

Connected.

SQL> grant newrole  to anand with admin option

  2  /

Grant succeeded.

SQL>

Login as ANAND again. This time the GRANT statement works:

SQL> conn anand/anand

Connected.

SQL> grant newrole to another_user

  2  /

Grant succeeded.

SQL>

IMPORT THE DATA WITHOUT EXPORTING ,DIRECTLY IMPORTING BY USING IMPDP

1   )   Importing the data from remotely without taking the export by database link :

Steps:

   Remote side :

·         Create a new user name called <prod>

Sql> Create user prod identified by prod;

·         Grant connect, resource ,dba   , imp_full_database,  exp_full_database to user prod;

·         Now log into user which we created

Conn prod/prod

·         Now create a db link

Create database link  <newlink>  connect scott identified by tiger using ‘remotedb’;

·         Now execute the impdb comment

$ ] Impdp prod/prod@testdb network_link=newlink schemas=scott remap_schema=scott:prod

--------------------------------------------------------------------------------------------------------

2)    Exporting data by expdp :

Expdp  username/password  dumpfile=<filename>   logfile=<filename> schemas=<schema name>  directory=<directory name>

For Example:

Expdp  scott/tiger   dumpfile=scott.dmp logfile=scott.log schemas=scott  directory=data

3)    Importing data by impdb:

Impdp username/username dumpfile=<filename> logfile=<filename> remap_schema=<from schema: to schema> directory=<directory name>

            For Example:

          Impdp  prod/prod  dumpfile=scott.dmp logfile=scott1.log remap_schema=scott:prod    schemas=scott
