Deployment of DataGuard and master-slave switchover

Master Database: vsgpdb
Standby Database: dgdb
 

1. confirm that the master database is in archive Mode
SQL> archive log list
Database log mode Archive Mode
Automatic archival Enabled
Archive destination/gp/arch
Oldest online log sequence 1307
Next log sequence to archive 1312
Current log sequence 1312
 

2. Set the primary database to force logging mode. Use the following statements:
SQL> select force_logging from v $ database;
 

FOR
---
YES
 

SQL> alter database force logging;
 

3. Configure the initialization parameters of the Primary database
Modify the client initialization parameter file and add the following content:
*. DB_UNIQUE_NAME = vsgpdb
*. LOG_ARCHIVE_CONFIG = 'dg _ CONFIG = (vsgpdb, dgdb )'
*. LOG_ARCHIVE_DEST_2 = 'service = dgdb lgwr sync affrem VALID_FOR = (ONLINE_LOGFILES, PRIMARY_ROLE) DB_UNIQUE_NAME = dgdb'
*. LOG_ARCHIVE_DEST_STATE_2 = DEFER
 

 

SQL> alter system set LOG_ARCHIVE_CONFIG = 'dg _ CONFIG = (vsgpdb, dgdb )';
SQL> alter system set LOG_ARCHIVE_DEST_2 = 'service = dgdb LGWR SYNC affsert
VALID_FOR = (ONLINE_LOGFILES, PRIMARY_ROLE) DB_UNIQUE_NAME = dgdb ';
SQL> alter system set LOG_ARCHIVE_DEST_STATE_2 = DEFER;
 

# -------- Configure the parameters of the standby role for role conversion
*. FAL_SERVER = DGDB
*. FAL_CLIENT = VSGPDB
*. DB_FILE_NAME_CONVERT = '/opt/ora10g/oradata/vsgpdb','/opt/dgdb/oradata/dgdb'
*. LOG_FILE_NAME_CONVERT = '/opt/ora10g/oradata/vsgpdb','/opt/dgdb/oradata/dgdb'
*. STANDBY_FILE_MANAGEMENT = AUTO
 

SQL> alter system set FAL_SERVER = DGDB;
 

System altered.
 

SQL> alter system set FAL_CLIENT = VSGPDB;
 

System altered.
 

SQL> alter system set DB_FILE_NAME_CONVERT = '/opt/ora10g/oradata/vsgpdb', '/opt/dgdb/oradata/dgdb ';
Alter system set DB_FILE_NAME_CONVERT = '/opt/ora10g/oradata/vsgpdb','/opt/dgdb/oradata/dgdb'
*
ERROR at line 1:
ORA-02096: specified initialization parameter is not modifiable with this
Option
 

 

SQL> alter system set DB_FILE_NAME_CONVERT = '/opt/ora10g/oradata/vsgpdb', '/opt/dgdb/oradata/dgdb','/gp/oradata ', '/opt/dgdb/oradata/dgdb' scope = spfile;
 

System altered.
 

SQL>
SQL> alter system set LOG_FILE_NAME_CONVERT = '/opt/ora10g/oradata/vsgpdb', '/opt/dgdb/oradata/dgdb' scope = spfile;
SQL> alter system set STANDBY_FILE_MANAGEMENT = AUTO;
Restart after modification
 

4. Create a control file-primary database operation
SQL> alter database create standby controlfile as '/opt/ora10g/oradata/vsgpdb/dgdb03.ctl ';
 

SQL> create pfile from spfile;
 

File created.
 

Shutdown immediate -- Be sure to turn off the master database and then transfer data files
 

5. transfer files to the standby Database
Initialize parameter files + control files + data files
SLAVE: 192.168.165.26 is the slave database IP address.
