Resolving Gaps in Data Guard Apply Using Incremental RMAN BAckup

Resolving Gaps in Data Guard Apply Using Incremental RMAN Backup:-

On the primary:

SQL> select name,database_role,switchover_status from v$database;

NAME      DATABASE_ROLE    SWITCHOVER_STATUS
--------- ---------------- --------------------
ORCL      PRIMARY          UNRESOLVABLE GAP

SQL> select current_scn from v$database;

CURRENT_SCN
-----------
    2076457

On the standby:

SQL> select database_role,switchover_status from v$database;

DATABASE_ROLE    SWITCHOVER_STATUS
---------------- --------------------
PHYSICAL STANDBY NOT ALLOWED

SQL> select current_scn from v$database;

CURRENT_SCN
-----------
    1998045

Solution:- 

1. [Standby] Stop the managed standby apply process:

SQL> alter database recover managed standby database cancel;
Database altered.

2. [Standby] Shutdown the standby database;

SQL> shutdown immediate
ORA-01109: database not open
Database dismounted.
ORACLE instance shut down.
SQL> 

3. [Primary] On the primary, take an incremental backup from the SCN number where the standby has been stuck;

RMAN> backup incremental from scn 1998045 database;

Starting backup at 15-SEP-14

Finished backup at 15-SEP-14

4. [Primary] On the primary, create a new standby controlfile:

SQL> alter database create standby controlfile as '/u01/neeraj/stdb_cont.ctl';
Database altered.

5. [Primary] Copy these files to standby host:

[oracle@localhost ~]$ cd /u01/neeraj/
[oracle@localhost neeraj]$ ls
29pij5mb_1_1  2apij5p1_1_1  stdb_cont.ctl
[oracle@localhost neeraj]$ 
[oracle@localhost neeraj]$ 
[oracle@localhost neeraj]$ scp * oracle@192.168.204.129:/u01/tspr

stdb_cont.ctl                                 100%   11MB  11.1MB/s   00:01    
[oracle@localhost neeraj]$ 

6. [Standby] Bring up the instance in nomount mode:

SQL> startup nomount
ORACLE instance started.

Variable Size             201328768 bytes
Database Buffers          864026624 bytes
Redo Buffers                4636672 bytes

7. [Standby] Check the location of the controlfile:

SQL> show parameter control_files

NAME                                 TYPE        VALUE
------------------------------------ ----------- ------------------------------
control_files                        string      /u01/app/oracle/oradata/stdb/control01.ctl   --- "rename or remove(control01_old.ctl)"

8. [Standby] Replace the controlfile with the one you just created in primary. and rename the existing file which is already exist on the standby.

$ cp /u01/tspr/stdb_cont.ctl /u01/app/oracle/oradata/stdb/control01.ctl

9.[Standby] Mount the standby database:

SQL> alter database mount standby database;

Database altered.

10 .[Standby] RMAN does not know about these files yet; so you must let it know – by a process called cataloging. Catalog these files:

RMAN> catalog start with '/u01/tspr';

searching for all files that match the pattern /u01/tspr

List of Files Unknown to the Database
=====================================
File Name: /u01/tspr/29pij5mb_1_1
File Name: /u01/tspr/2apij5p1_1_1

Do you really want to catalog the above files (enter YES or NO)? yes
cataloging files...
cataloging done

List of Cataloged Files
=======================
File Name: /u01/tspr/29pij5mb_1_1
File Name: /u01/tspr/2apij5p1_1_1

11 .Recover these files:

RMAN> recover database;

Note:- After some time, the recovery fails with the message. This happens because we have come to the last of the archived logs.

12 .At this point exit RMAN and start managed recovery process:

SQL> alter database recover managed standby database disconnect from session;

On the primary database:

Table_exists_action Parameter of Data Pump

Table_exists_action Parameter of Data Pump
Sometimes we need to import table into an existing table.If we import the table in that schemas it throws error that table already exist. If we have to reserve the old data of table and append the new data, we can use the table_exists_action parameter of data pump. Some valid keywords are (SKIP | APPEND | TRUNCATE | REPLACE).

The possible values of the following effects are:-

1.) SKIP: - says to ignore the data in the import file and leave the existing table untouched. This is not a valid option if the CONTENT parameter is set to DATA_ONLY.By default the value is SKIP.

2.) APPEND: - loads rows from the source and leaves existing rows unchanged.

3.) TRUNCATE: - truncate the exiting rows in the table and insert the rows from the dump. The truncate option cannot be used over a db link or with a cluster table.

4.) REPLACE: - says to delete the whole table and replace both the table definition and rows from the import dmp file. This is not a valid option if the CONTENT parameter is set to DATA_ONLY.

example :- 

SQL> create user rudra identified by rudra default tablespace mmoney quota unlimited on mmoney;
User created.
SQL> grant create session,resource to rudra;
Grant succeeded.
SQL> create or replace directory abc as '/u01/neeraj';
Directory created.
SQL> grant read,write on directory abc to rudra;
Grant succeeded.

SQL> conn
Enter user-name: rudra
Enter password:
Connected.
SQL> create table r1(id number,name varchar2(20));
Table created.
SQL> insert into r1 values(1,'rudra');
1 row created.
SQL> insert into r1 values(2,'manoj');
1 row created.
SQL> /
1 row created.
SQL> /
1 row created.
SQL> commit;
Commit complete.
SQL> select * From r1;
