Step By Step Dataguard Implementation (oracle 10g)


Your Pfile in primary should have entries like the following entries:

Tasks must perform on PRIMARY :

On Primary site

1. Install oracle
2. Create database by dbca
3. Create archivelog location
4. Turn on force logging on primary database:

ALTER DATABASE FORCE LOGGING;

select * from v$pwfile_users;

select bytes from v$log;

select group#, member from v$logfile;

5. Adding standby redo log group.

ALTER DATABASE ADD STANDBY LOGFILE GROUP 5(‘DATAFILE_LOCATION/ULTIMUS/redo07.log’) SIZE 100M;

ALTER DATABASE ADD STANDBY LOGFILE GROUP 6 (‘DATAFILE_LOCATION/ULTIMUS/redo08.log’)SIZE 100M;

ALTER DATABASE ADD STANDBY LOGFILE GROUP 7 ('DATAFILE_LOCATION/ULTIMUS/redo09.log')SIZE 100M;

select * from v$standby_log;


6. shutdown immediate;
7. startup mount;
8. alter database archivelog;
9. alter database open;
    archive log list;
10. startup mount;

11. Create standby control file and transfer it to Standby.
alter database create standby controlfile as ‘DATAFILE_LOCATION/ULTIMUS/STAN.ctl’;
12. ALTER DATABASE OPEN;
13. Recheck init file,tnsname,listener file.
14. create spfile.
15. start listener
16. tnsping
17. shutdown




 Init file in standby server

*.undo_management='AUTO'
*.undo_tablespace='UNDOTBS1'
*.user_dump_dest='AUDIT_FILE_LOCATION/STAN/udump'
STANDBY_FILE_MANAGEMENT=AUTO


 On standby site

1. install oracle
2. create database by dbca,
3. shutdown.delete datafile
3. create archivelog location
4. copy datafile,tnsname.ora,lIstener.ora
5. delete control file except standby,delete standby redo file
5. recheck pfile.
6. startup mount pfile
OR. startup   mount pfile='$ORACLE_HOME/dbs/initSTAN.ora'

7. if necessary:

ALTER DATABASE DROP LOGFILE GROUP 5;
ALTER DATABASE DROP LOGFILE GROUP 6;
ALTER DATABASE DROP LOGFILE GROUP 7;

8. Add stanby redo log group:

ALTER DATABASE ADD STANDBY LOGFILE GROUP 5(‘DATAFILE_LOCATION/STAN/redo07.log’) SIZE  100M;

ALTER DATABASE ADD STANDBY LOGFILE GROUP  6(‘DATAFILE_LOCATION/STAN/redo08.log’) SIZE  100M;

ALTER DATABASE ADD STANDBY LOGFILE GROUP  7(‘DATAFILE_LOCATION/STAN/redo09.log’) SIZE  100M;

select * from v$standby_log;

9. start listener
10. tnsping
11. shutdown immediate
12. startup mout pfile

13. to start log applying to secondary:

alter database recover managed standby database disconnect; ---apply cuurent logfile

* To check archives are applied to secondary, issue the following command.

select sequence#,first_time,applied from v$archived_log order by first_time;

* To check if the process MRPO exists in secondary, issue the command.
SELECT PROCESS FROM V$MANAGED_STANDBY WHERE PROCESS LIKE 'MRP%';

EXPDP/IMPDP Export/Import dumpfile to a Remote Server Using Network_Link.

EXPDP/IMPDP Export/Import dumpfile to a Remote Server Using Network_Link. Step 1:   First you have to create a TNS entry at destination database which will be used to connect to the remote target database. pumplink =   (DESCRIPTION =     (ADDRESS_LIST =       (ADDRESS = (PROTOCOL = TCP)(HOST = 172.17.1.171)(PORT = 1521))     )     (CONNECT_DATA =       (SERVER = DEDICATED)       (SERVICE_NAME = Ultimus)     )   ) Step 2:   Connect to SQL plus: --Issue the following command to create db link on destination database: CREATE PUBLIC DATABASE LINK pumplink    connect to scott identified by tiger USING 'pumplink'; Step 3:   Issue the expdp command on the destination server using Network_link parameter: expdp scott/tiger directory= dumpdir logfile=impi_temp.log network_link= pumplink  schemas=scott dump...

Solution of problem: Resultset Exceeds the Maximum Size (100 MB)

Solution of problem: Resultset Exceeds the Maximum Size (100 MB) I was running a select statement in PL/SQL Developer. it was a short query but the data volume that the query was fetching was huge. But when ever i Click the button Fetch Last Page or press 'ALT+End' button a message box comes after a while saying: Then I started looking for the exact reason of this sort of problem in Google. When I realized there was no direct solution in the web, I started looking the PL/SQL Developer Software menu and found the ultimate solution. The reason of this problem is there is a parameter of maximum result set size in PL/SQL Developer Software which is by default set to 100 MB. To change this parameter you have to go to the following location: 1. Goto Edit Menu and click ' PL/SQL Beautifier Options '. A new window will open. 2. Click SQL Window of " Window Types ". 3. Now Change the value of "Maximum Result Set Size( 0 is unlimited)"  ...
