Setup Standby Database on One PC
Building the Data Guard
1. Check the primary database name:
SQL> select name from v$database;
NAME
---------
BSL01LAB
2. Enable Forced logging
--check FORCE LOGGING status
SQL> select force_logging from v$database;
FOR
---
NO
--eable FORCE LOGGING
SQL> alter database force logging;
Database altered.
--Verify
SQL> select force_logging from v$database;
FOR
---
YES
3. Create a password file
--To create the password file
D:oracleproduct10.2.0db_1database>orapwd file=PWDbsl01lab.ora password=dow entries=5
--To verify the new password file
D:oracleproduct10.2.0db_1database>sqlplus /nolog

SQL> connect sys/dow as sysdba
Connected to an idle instance.
4. Configure a Standby Redo Log
Step 1 Ensure log file sizes are identical on the primary and standby database
SQL> select group#,thread#,bytes/1024/1024,members from v$log;
GROUP# THREAD# BYTES/1024/1024 MEMBERS
---------- ---------- --------------- ----------
1 1 50 1
2 1 50 1
3 1 50 1
Step 2 Determine the appropriate number of standby redo log file groups
The minimal number should be 3+1=4
Step 3 Verify related database parameters and settings
Maxlogfiles
Maxlogmembers
Step 4 Create standby redo log file groups
SQL> alter database add standby logfile ('D:ORACLEPRODUCT10.2.0ORADATABSL01LABredo01d.log') size 50M;
Database altered.
SQL> alter database add standby logfile ('D:ORACLEPRODUCT10.2.0ORADATABSL01LABredo02d.log') size 50M;
Database altered.
SQL> alter database add standby logfile ('D:ORACLEPRODUCT10.2.0ORADATABSL01LABredo03d.log') size 50M;
Database altered.
Step 5 Verify the standby redo log file groups were created
SQL> select group#,thread#,sequence#,archived,status from v$standby_log;
GROUP# THREAD# SEQUENCE# ARC STATUS
---------- ---------- ---------- --- ----------
4 0 0 YES UNASSIGNED
5 0 0 YES UNASSIGNED
6 0 0 YES UNASSIGNED
