Oracle 12c (12.2.0.1) binaries Installation on Oracle Linux 7

In this post, I’m installing the Oracle Database 12c Release 2 (12.2.0.1.0) software on Oracle Linux 7.4.  Only the software is being installed at this point.

First and foremost, before you start, make sure your Linux server meets the minimum hardware requirements:

• 1GB of RAM (plus appropriately sized swap space)
• 6.4GB of disk space for the software installation
• 1GB of disk space for your /tmp directory

Download the database 12c software

You need to download both Oracle Database 12cR2 parts from the Oracle Technology Network (OTN).

Once you’ve downloaded the software, unzip file to a staging area:

[oracle@localhost 12c]$ ll

total 3372756

drwxr-xr-x. 7 oracle oinstall       4096 Jan 26  2017 database

-rw-r--r--. 1 oracle oinstall 3453696911 Nov 11 00:22 linuxx64_12201_database.zip

[oracle@localhost 12c]$ cd database/

[oracle@localhost database]$ ll

total 24

drwxr-xr-x.  4 oracle oinstall 4096 Jan 26  2017 install

drwxrwxr-x.  2 oracle oinstall   61 Jan 26  2017 response

-rwxr-xr-x.  1 oracle oinstall  500 Feb  7  2013 welcome.html

[oracle@localhost database]$ 

So we successfully completed the software installation of Oracle 12CR2. Happy DBA'ing :)

Rolling forward physical standby database using RMAN incremental SCN backup

Rolling forward physical standby database using RMAN incremental SCN backup 
*************************************************************************************************

At PRIMARY database

SQL> select max(sequence#) from v$archived_log where applied='YES';

MAX(SEQUENCE#)
--------------
            17

At STANDBY database

SQL> select max(sequence#) from v$archived_log where applied='YES';

MAX(SEQUENCE#)
--------------
            10

Mistakenly archive log sequence no 11 deleted from primary database archive log location, till archive logs#16 received at physical standby.
But due missing archive log# 11, MRP process has been stopped, which results archive log gap. 

Below is practical illustration, how to roll forward physical standby databases using RMAN incremental SCN backup.


1) Take min SCN from out of 3 queries from Physical standby

SQL> SELECT CURRENT_SCN FROM V$DATABASE;

CURRENT_SCN
-----------------
962773 

SQL> select database_role, current_scn from v$database;

SQL> select min(checkpoint_change#) from v$datafile_header;

2) Stop MRP process at standby database

ALTER DATABASE RECOVER MANAGED STANDBY DATABASE CANCEL;

3) Check MRP status

select RECOVERY_MODE from v$archive_dest_status;
select process,sequence#,status from v$managed_standby;

4) Take SCN based backup from primary database in order to sync with physical standby

$ rman target sys/dg123@prod

5) Copy RMAN backup including controlfile to standby FRA.

6) Connect RMAN to standby target

Step by step Physical standby database creation using RMAN DUPLICATE in oracle 11g.
*******************************************************************************************************

Oracle binaries installed with one stand alone database created.

IP: 192.168.56.2
Primary DB_NAME=prod
Primary DB_UNIQUE_NAME=prod

on Physical standby, I have installed only oracle binaries.

IP: 192.168.56.3
Primary DB_NAME=prod
Primary DB_UNIQUE_NAME=stdby

Required Parameters:
********************
                          
DB_NAME    - Must be same on primary & on all standby
DB_UNIQUE_NAME    - Must be UNIQUE on all database respectively
LOG_ARCHIVE_CONFIG    - This parameter includes DB_UNIQUE_NAME which are the part of DATAGUARD configuration
LOG_ARCHIVE_DEST_n    - Define Local & Remote archive log file location
LOG_ARCHIVE_DEST_STATE_n - Define state of archiving (ENABLE or DEFER)
REMOTE_LOGIN_PASSWORDFILE - Must be in EXCLUSIVE mode
FAL_SERVER - Use for archivelog gap resolution (required only in physical standby server)
DB_FILE_NAME_CONVERT - Required when directory structure is different FOR datafiles
LOG_FILE_NAME_CONVERT - Required when directory structure is different FOR logfiles
STANDBY_FILE_MANAGEMENT - Keep AUTO to create file automatically on standby


STEPS:
******
on PRIMARY database:

1) ENABLE ARCHIVELOG MODE

SELECT LOG_MODE FROM V$DATABASE;

IF ARCHIVELOG MODE is DISABLE, follow below steps to enable it.

SHUT IMMEDIATE;
STARTUP MOUNT;
ALTER DATABASE ARCHIVELOG;
ALTER DATABASE OPEN;

2) ENABLE FORCE LOGGING MODE

SELECT FORCE_LOGGING FROM V$DATABASE;

ALTER DATABASE FORCE LOGGING;

3) VERIFY DB_NAME & DB_UNIQUE_NAME OF Primary Database

SHOW PARAMETER DB_NAME;
SHOW PARAMETER DB_UNIQUE_NAME;

4) CONFIGURE LOG_ARCHIVE_CONFIG PARAMETER

ALTER SYSTEM SET LOG_ARCHIVE_CONFIG='DG_CONFIG=(prod,stdby)';

5) SET ARCHIVELOG DESTINATION FOR STANDBY 

ALTER SYSTEM SET LOG_ARCHIVE_DEST_2='SERVICE=ngprd VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE) DB_UNIQUE_NAME=ngprd';

ALTER SYSTEM SET LOG_ARCHIVE_DEST_STATE_2=ENABLE;

6) SET REMOTE LOGIN PASSWORD TO EXCLUSIVE

ALTER SYSTEM SET REMOTE_LOGIN_PASSWORDFILE=EXCLUSIVE SCOPE=SPFILE;

SHOW PARAMETER REMOTE_LOGIN_PASSWORDFILE;

7) SET FAL_SERVER PARAMETER

ALTER SYSTEM SET FAL_SERVER=stdby;

8) ALTER SYSTEM SET STANDBY_FILE_MANAGEMENT=AUTO;

9) CONFIGURE REQUIRED NETWORK SERVICES using "NETMGR"


10) CREATE STANDBY CONTROLFILE & PFILE

ALTER DATABASE CREATE STANDBY CONTROLFILE AS '/tmp/stndcnt.ctl';
CREATE PFILE='/tmp/initstdby.ora' FROM SPFILE;

11) MODIFY initstdby.ora file 

i)   change DB_UNIQUE_NAME
ii)  change FAL_SERVER
iii) change log_archive_dest_n
iv)  change location of controlfile

To achieve switchover & switchback (DR) activity, modify same parameters as in production into standby pfile.

12) CREATE APPROPRIATE DIRECTORY STRUCTURE AND MOVE BACKUP, PASSWORD FILE, CONTROLFILE & PFILE

NOTE:- If you fail to move password file to standby destination, you will face below error, while transporting logs to standy site.

ORA-01031: insufficient privileges

In order to rectify this error, move password file to $ORACLE_HOME/dbs location and rename with ora$ORACLE_SID.


ON PHYSICAL SERVER:
*******************
1) CREATE NETWORK SERVICES & UPDATE /etc/oratab FILE

2) START LISTENER on BOTH database

3) Startup database in nomount with updated standby pfile.
