Create a physical standby database

Summary

This is the basic procedure from the Data Guard manual. This does not use RMAN DUPLICATE or Cloud Control.

The primary database is on PADSTOW with the physical standby database on BOTANY.

Preparation

Create Database

I created the OCM12PRI CDB on PADSTOW using dbca. It has one (1) PDB: EXAMPLES.

Enable Force Logging

Following the procedure in “3.1.1 Enable Forced Logging”, I ran the following commands on PADSTOW as the ORACLE user:

sqlplus / as sysdba

The output is:

SQL*Plus: Release 12.1.0.2.0 Production on Wed Jul 4 20:44:38 2018

Copyright (c) 1982, 2014, Oracle.  All rights reserved.

Connected to an idle instance.

Startup the database instance in MOUNT mode:

startup mount

The output is:

ORACLE instance started.
Total System Global Area 1258291200 bytes
Fixed Size          2923920 bytes
Variable Size         822084208 bytes
Database Buffers      419430400 bytes
Redo Buffers           13852672 bytes

Database mounted.

Determine the current settings:

select name, log_mode, force_logging from v$database;

The output is:

NAME      LOG_MODE     FORCE_LOGGING
--------- ------------ ---------------------------------------

OCM12PRI NOARCHIVELOG NO

Change the settings with the following commands:

ALTER DATABASE FORCE LOGGING;
ALTER DATABASE ARCHIVELOG;

Verify that the settings are correct:

select name, log_mode, force_logging from v$database;

The output is:

NAME      LOG_MODE     FORCE_LOGGING
--------- ------------ ---------------------------------------

OCM12PRI ARCHIVELOG YES

In addition to enabling FORCE LOGGING, I also enabled ARCHIVELOG mode.

Redo Transport Authentication

Since I do not have OID configured in my environment, there is no need to Configure Redo Transport Authentication.

Configure the Primary Database to Receive Redo Data

Since this environment is only used for a fast fail-over test, there is no need to Configure the Primary Database to Receive Redo Data.

Set Primary Database Initialization Parameters

For the list of parameters described in “3.1.4 Set Primary Database Initialization Parameters”, I ran the following query to get current values:

COLUMN name   FORMAT A25
COLUMN value  FORMAT A50
SET PAGESIZE 100
SELECT
     name,
     value
   FROM
     v$parameter
   WHERE
     NAME IN (
       'db_name',
       'db_unique_name',
       'log_archive_config',
       'control_files',
       'log_archive_dest_1',
       'log_archive_dest_2',
       'remote_login_passwordfile',
       'log_archive_format'
     )
   ORDER BY
     name
/

The result was:

NAME                      VALUE
------------------------- --------------------------------------------------
control_files             /opt/app/oracle/oradata/ocm12pri/control01.ctl, /o

db_unique_name            ocm12pri_padstow
log_archive_config
log_archive_dest_1
log_archive_dest_2
log_archive_format        %t_%s_%r.dbf
remote_login_passwordfile EXCLUSIVE

8 rows selected.

Added the following lines to /opt/app/oracle/product/12.1.0/dbhome_1/network/admin/tnsnames.ora on PADSTOW:

OCM12PRI_BOTANY =
   (DESCRIPTION =
     (ADDRESS = (PROTOCOL = TCP)(HOST = botany.yaocm.id.au)(PORT = 1521))
     (CONNECT_DATA =
       (SERVER = DEDICATED)
       (SERVICE_NAME = ocm12pri_botany.yaocm.id.au)
     )
   )

Verified the changes as follows:

tnsping ocm12pri_botany

The output was:

TNS Ping Utility for Linux: Version 12.1.0.2.0 - Production on 14-JUL-2018 21:34:53

OK (10 msec)

In all, I only had to make the following three (3) parameter changes:

ALTER SYSTEM SET log_archive_config='DG_CONFIG=(OCM12PRI_PADSTOW,OCM12PRI_BOTANY)';
ALTER SYSTEM SET log_archive_dest_1='LOCATION=USE_DB_RECOVERY_FILE_DEST VALID_FOR=(ALL_LOGFILES,ALL_ROLES) DB_UNIQUE_NAME=OCM12PRI_PADSTOW';

ALTER SYSTEM SET log_archive_dest_2='SERVICE=OCM12PRI_BOTANY ASYNC VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE) DB_UNIQUE_NAME=OCM12PRI_BOTANY';

The new set of parameters are:

  8 rows selected.

Since I only plan to do fail-over tests, there is now need to configure the other parameters or to allocate standby redo log files.

Enable Archiving

I had already enabled archiving earlier (see 3.1.5 Enable Archiving for procedure).

Creating a Physical Standby

Task 1: Create a Backup Copy of the Primary Database Data Files

Followed the procedure in “3.2.1 Creating a Physical Standby Task 1: Create a Backup Copy of the Primary Database Data Files”.

I used the following RMAN commands to backup the database:

run {
   allocate channel d1 device type disk;
   allocate channel d2 device type disk;
   backup database archivelog all delete input;
   delete noprompt obsolete;
}

The RMAN output is as follows:

using target database control file instead of recovery catalog
allocated channel: d1 channel d1: SID=85 device type=DISK

allocated channel: d2 channel d2: SID=82 device type=DISK

Note:

The above warnings are caused by the Data Guard settings I had configured earlier in that the marked archived redo log files have not been yet applied the non-existent standby database as specified in the parameter, log_archive_dest_2.

To make the copying of the RMAN backup files easier, I used the following RMAN command to backup the entire recovery area to /tmp:

Task 2: Create a Control File for the Standby Database

Followed the procedure in “3.2.2 Creating a Physical Standby Task 2: Create a Control File for the Standby Database”.

ALTER DATABASE CREATE STANDBY CONTROLFILE AS '/tmp/botany.ctl';

Task 3: Create a Parameter File for the Standby Database

Followed the procedure in “3.2.3 Creating a Physical Standby Task 3: Create a Parameter File for the Standby Database”.

CREATE PFILE='/tmp/initpadstow.ora' FROM SPFILE;

I used the following commands to make changes to the proposed parameter file for the standby database on BOTANY:

[oracle@padstow ~]$ cp /tmp/initpadstow.ora /tmp/initbotany.ora [oracle@padstow ~]$ vi /tmp/initbotany.ora [oracle@padstow ~]$ diff /tmp/initpadstow.ora /tmp/initbotany.ora 21c21 < *.db_unique_name='ocm12pri_padstow' --- > *.db_unique_name='ocm12pri_botany' 24a25 > *.fal_server='ocm12pri_padstow' 27,28c28 < *.log_archive_dest_1='LOCATION=USE_DB_RECOVERY_FILE_DEST VALID_FOR=(ALL_LOGFILES,ALL_ROLES) DB_UNIQUE_NAME=OCM12PRI_PADSTOW' < *.log_archive_dest_2='SERVICE=OCM12PRI_BOTANY ASYNC VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE) DB_UNIQUE_NAME=OCM12PRI_BOTANY' --- > *.log_archive_dest_1='LOCATION=USE_DB_RECOVERY_FILE_DEST VALID_FOR=(ALL_LOGFILES,ALL_ROLES) DB_UNIQUE_NAME=OCM12PRI_BOTANY'

Note:

The above changes are much simpler than the ones given in “3.2.3 Creating a Physical Standby Task 3: Create a Parameter File for the Standby Database” because I am not going to do a switchover.

I did not include the following system parameters because the current files do not include the DB unique name:

The values currently are:

Task 4: Copy Files from the Primary System to the Standby System

Followed the procedure in “3.2.4 Creating a Physical Standby Task 4: Copy Files from the Primary System to the Standby System”.

Ran the following commands to copy the files from PADSTOW to BOTANY:

scp /tmp/botany.ctl botany:/tmp scp /tmp/initbotany.ora botany:/tmp scp /tmp/padstow.gz botany:/tmp scp /opt/app/oracle/product/12.1.0/dbhome_1/dbs/orapwocm12pri botany:/opt/app/oracle/product/12.1.0/dbhome_1/dbs

Used the following command to restore the backup of the recovery area from PADSTOW into the current directory on BOTANY:

tar xvzf /tmp/padstow.gz

The output was:

tmp/OCM12PRI_PADSTOW/ tmp/OCM12PRI_PADSTOW/backupset/ tmp/OCM12PRI_PADSTOW/backupset/2018_07_14/ tmp/OCM12PRI_PADSTOW/backupset/2018_07_14/o1_mf_nnndf_TAG20180714T215755_fnmv41p9_.bkp tmp/OCM12PRI_PADSTOW/backupset/2018_07_14/o1_mf_annnn_TAG20180714T222835_fnmv3mlz_.bkp tmp/OCM12PRI_PADSTOW/backupset/2018_07_14/o1_mf_ncsnf_TAG20180714T220024_fnmv6s0g_.bkp tmp/OCM12PRI_PADSTOW/backupset/2018_07_14/o1_mf_nnndf_TAG20180714T215755_fnmv5mt2_.bkp tmp/OCM12PRI_PADSTOW/708E7D80672721D0E0536E01A8C0111B/ tmp/OCM12PRI_PADSTOW/708E7D80672721D0E0536E01A8C0111B/backupset/ tmp/OCM12PRI_PADSTOW/708E7D80672721D0E0536E01A8C0111B/backupset/2018_07_14/ tmp/OCM12PRI_PADSTOW/708E7D80672721D0E0536E01A8C0111B/backupset/2018_07_14/o1_mf_nnndf_TAG20180714T215755_fnmv6kxr_.bkp tmp/OCM12PRI_PADSTOW/708E7D80672721D0E0536E01A8C0111B/backupset/2018_07_14/o1_mf_nnndf_TAG20180714T215755_fnmv62vw_.bkp tmp/OCM12PRI_PADSTOW/708F04B2A880250FE0536E01A8C01CF7/ tmp/OCM12PRI_PADSTOW/708F04B2A880250FE0536E01A8C01CF7/backupset/ tmp/OCM12PRI_PADSTOW/708F04B2A880250FE0536E01A8C01CF7/backupset/2018_07_14/ tmp/OCM12PRI_PADSTOW/708F04B2A880250FE0536E01A8C01CF7/backupset/2018_07_14/o1_mf_nnndf_TAG20180714T215755_fnmv4tr2_.bkp tmp/OCM12PRI_PADSTOW/708F04B2A880250FE0536E01A8C01CF7/backupset/2018_07_14/o1_mf_nnndf_TAG20180714T215755_fnmv3to3_.bkp

Move the backups from the current directory back to the /tmp directory:

mv tmp/OCM12PRI_PADSTOW /tmp

Create the required directories on BOTANY:

mkdir -p /opt/app/oracle/oradata/ocm12pri mkdir -p /opt/app/oracle/fast_recovery_area/ocm12pri mkdir -p /opt/app/oracle/oradata/ocm12pri/examples mkdir -p /opt/app/oracle/oradata/ocm12pri/pdbseed

Update /etc/oratab as follows:

cat >>/etc/oratab <<DONE ocm12pri:/opt/app/oracle/product/12.1.0/dbhome_1:N DONE

Task 5: Set Up the Environment to Support the Standby Database

Followed the procedure in “3.2.5 Creating a Physical Standby Task 5: Set Up the Environment to Support the Standby Database”.

2. Copy Remote Password File to Botany

Ran the following command on PADSTOW:

scp $ORACLE_HOME/dbs/orapwocm12pri botany:$ORACLE_HOME/dbs/

3. Configure and Start Listener on Botany

Listener was already configure when BOTANY was cloned from PADSTOW. This is confirmed as follows:

lsnrctl status

The output is:

LSNRCTL for Linux: Version 12.1.0.2.0 - Production on 23-JUL-2018 19:58:53 Copyright (c) 1991, 2014, Oracle. All rights reserved.

4. Create Oracle Net service names

Added the following lines to /opt/app/oracle/product/12.1.0/dbhome_1/network/admin/tnsnames.ora on BOTANY:

OCM12PRI_PADSTOW = (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = padstow.yaocm.id.au)(PORT = 1521)) (CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = ocm12pri_padstow.yaocm.id.au) ) )

Verified the changes as follows:

tnsping ocm12pri_padstow

The output was:

TNS Ping Utility for Linux: Version 12.1.0.2.0 - Production on 23-JUL-2018 21:28:12 Copyright (c) 1997, 2014, Oracle. All rights reserved.

5. Create SPFILE

Configure an environment for an idle instance (on BOTANY) as follows:

. oraenv

Use the following parameters:

ORACLE_SID = [personal] ? ocm12pri ORACLE_HOME = [/home/oracle] ? /opt/app/oracle/product/12.1.0/dbhome_1 The Oracle base remains unchanged with value /opt/app/oracle

Start session with an idle instance as follows:

sqlplus / as sysdba

The output is:

SQL*Plus: Release 12.1.0.2.0 Production on Mon Jul 23 21:31:35 2018 Copyright (c) 1982, 2014, Oracle. All rights reserved. Connected to an idle instance.

Convert the parameter file into a SPFILE as follows:

create spfile from pfile='/tmp/initbotany.ora';

The expected output is:

File created.

Exit from SQL*Plus as follows as all following commands will be done through RMAN:

exit

The expected output is:

Disconnected from Oracle Database 12c Enterprise Edition Release 12.1.0.2.0 - 64bit Production With the Partitioning, OLAP, Advanced Analytics, Real Application Testing and Unified Auditing options

Task 6: Start the Physical Standby Database

Note:

There is a missing step here: I did not record how I used the standby control (/tmp/botany.ctl) to create the cotrolfiles on the physical standby.

Followed the procedure in “3.2.6 Creating a Physical Standby Task 6: Start the Physical Standby Database”.

Start a RMAN session (on BOTANY):

rman target /

Sample output is:

Recovery Manager: Release 12.1.0.2.0 - Production on Fri Aug 3 21:45:27 2018 Copyright (c) 1982, 2014, Oracle and/or its affiliates. All rights reserved. connected to target database (not started)

Mount the database:

startup mount

Sample output is:

Oracle instance started database mounted Total System Global Area 1224736768 bytes Fixed Size 2923824 bytes Variable Size 771752656 bytes Database Buffers 436207616 bytes Redo Buffers 13852672 bytes

Restore the database as follows:

restore database;

Sample output is:
