Step by step to configure Oracle DataGuard in Oracle 10g

Step by step to configure Oracle DataGuard in Oracle 10g

The Enviroment 

2 Linux servers, Oracle Distribution 2.6.9-55 EL i686 i386 GNU/Linux
Oracle Database 10g Enterprise Edition Release 10.2.0.1.0
ssh is configured for user oracle on both nodes
Oracle Home is on identical path on both nodes

Implementation notes: 

Once you have your primary database up and running these are the steps to follow:

1.  Enable Forced Logging
2.  Create a Password File
3.  Configure a Standby Redo Log
4.  Enable Archiving
5.  Set Primary Database Initialization Parameters

Having followed these steps to implement the Physical Standby you need to follow these steps:

1.  Create a Control File for the Standby Database
2.  Backup the Primary Database and transfer a copy to the Standby node.
3.  Prepare an Initialization Parameter File for the Standby Database
4.  Configure the listener and tnsnames to support the database on both nodes
5.  Set Up the Environment to Support the Standby Database on the standby node.
6.  Start the Physical Standby Database
7.  Verify the Physical Standby Database Is Performing Properly

Enable Forced Logging

In order to implement Standby Database we enable 'Forced Logging'.

This option ensures that even in the event that a 'nologging' operation is done, force logging takes precedence and all operations are logged
into the redo logs.

SQL> ALTER DATABASE FORCE LOGGING;

Database altered.  

Create a Password File

A password file must be created on the Primary and copied over to the Standby site. The sys password must be identical on both sites. This is
a key pre requisite in order to be able to ship and apply archived logs from Primary to Standby.

cd $ORACLE_HOME/dbs
[vmractest1] > orapwd file=orapwwhiteowl password=oracle force=y

Configure a Standby Redo Log

A Standby Redo log is added to enable Data Guard Maximum Availability and Maximum Protection modes. It is important to configure the
Standby Redo Logs (SRL) with the same size as the online redo logs.
In this example I'm using Oracle Managed Files, that's why I don't need to provide the SRL path and file name. If you are not using OMF's
you then must pass the full qualified name.

Enable Archiving

On 10g you can enable archive log mode by mounting the database and executing the archivelog command:

SQL> startup mount;

Set Primary Database Initialization Parameters

Data Guard must use spfile, in order to configure it we create and configure the standby parameters on a regular pfile, and once it is ready we
convert it to an spfile.
Several init.ora parameters control the behavior of a Data Guard environment. In this example the Primary database init.ora is configured so
that it can hold both roles, as Primary or Standby.

SQL> create pfile='/oradisk/app01/oracle/product/10gDB/dbs/pfilewhiteowl.ora'  from spfile;

File created.

Edit the pfile to add the standby parameters, here shown highlighted:

db_name='whiteowl'
db_unique_name='whiteowl' 
LOG_ARCHIVE_CONFIG='DG_CONFIG=(whiteowl,blackowl)' 
control_files='/vmasmtest/od01/WHITEOWL/WHITEOWL/controlfile/o1_mf_310n1xf0_.ctl'

Once the new parameter file is ready we create from it the spfile:

Backup the Primary Database and transfer a copy to the Standby node.

Generate a script to copy datafiles

On the standby node create the required directories to get the datafiles

[root@vmractest2 root]# mkdir -p /oradisk/od01/BLACKOWL/datafile/
[root@vmractest2 root]# mkdir -p /oradisk/od01/BLACKOWL/onlinelog/
[root@vmractest2 root]# chown -R oracle:dba /oradisk/od01

On the primary node execute the script to copy the database while the main database is down (or in backup mode)
