Step by Step Creating a physical standby database on Oracle 11.2.0.1.0 using RMAN

Creating a physical standby database on Oracle 11.2.0.1.0 using RMAN :-

OS Version:-Red Hat Enterprise Linux Server release 6.4
Oracle version:- Oracle Database 12c Enterprise Edition Release 11.2.0.1.0 64bit
Primary database:- prim
Standby database:- stand

System Configuration

primary server:-

edit the following files

vi /etc/hosts

192.168.2.102   server1.soumya.com      server1
192.168.2.104   server2.soumya.com      server2

:wq

vi /etc/sysconfig/network
HOSTNAME=server1.soumya.com

:wq

vi /etc/sysconfig/network-scripts/ifcfg-eth0

NETMASK=255.255.255.0
IPADDR=192.168.2.102
GATEWAY=192.168.2.1

:wq

Standby Server:-

edit the following files

vi /etc/hosts

192.168.2.102   server1.soumya.com      server1
192.168.2.104   server2.soumya.com      server2
:wq

vi /etc/sysconfig/network

HOSTNAME=server2.soumya.com

:wq

vi /etc/sysconfig/network-scripts/ifcfg-eth0

NETMASK=255.255.255.0
IPADDR=192.168.2.104
GATEWAY=192.168.2.1

:wq

In both server-- # service network restart
                 # service NetworkManager restart
                # service iptables stop
                # chkconfig iptables off
                #vi /etc/selinux/config and disable selinux .
                After changing inside the file please restart the server.

We have a database called prim on primary server and we will install only oracle binaries on
standby server(192.168.2.104).No database should be running in standby server.


Oracle Net configuration:-

Listener.ora configuration for primary database (prim) in primary server (192.168.2.102)

vi $ORACLE_HOME/network/admin/listener.ora

SID_LIST_LISTENER =
(SID_LIST =
    (SID_DESC =
      (GLOBAL_DBNAME = prim)
      (ORACLE_HOME = /u01/app/oracle/product/11.2.0/db_1)
      (SID_NAME = prim)
    )
)
LISTENER =
(DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = server1.soumya.com)(PORT = 1521))
)
ADR_BASE_LISTENER = /u01/app/oracle

:wq

Listener.ora configuration for standby database (stand) in standby server (192.168.2.104)
vi $ORACLE_HOME/network/admin/listener.ora

SID_LIST_LISTENER =
(SID_LIST =
    (SID_DESC =
      (GLOBAL_DBNAME = stand)
      (ORACLE_HOME = /u01/app/oracle/product/11.2.0/db_1)
      (SID_NAME = stand)
    )
)
LISTENER =
(DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = server2.soumya.com)(PORT = 1521))
)
ADR_BASE_LISTENER = /u01/app/oracle

:wq

On both server(192.168.2.102 & 192.168.2.104), add Oracle Net aliases for both databases and aux alias for RMAN DUPLICATE in
tnsnames.ora:

vi $ORACLE_HOME/network/admin/tnsnames.ora

prim =
(DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = server1.soumya.com)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = prim)
    )
)

stand =
(DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = server2.soumya.com)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = stand)
    )
)

-save & exit(:wq )

Now we will have to start listener in primary and standby server:-

$ lsnrctl start

Check "tnsping prim" & "tnsping stand" in both server. If output of both command is
coming as "ok" that means oracle net service has been added successfully.

In primary database:-
Put the database in archivelog mode.

In Primary Database:-

Enable force logging The FORCE LOGGING option to ensure that all the changes made in the database
will be captured and available for recovery in the redo logs.

SQL> alter database force logging;
Database altered.

SQL> select force_logging from v$database;

FORCE_LOGGING
---------------------------------------
YES

Create a password file
$ orapwd file=$ORACLE_HOME/dbs/orapwprim password=redhat
$ cd $ORACLE_HOME/dbs/
$ chmod 775 orapwprim
$ cp orapwprim orapwstand

Now transfer the password file into standby server using scp command
$ scp orapwstand oracle@192.168.2.104:/u01/app/oracle/product/11.2.0/db_1/dbs/

Add following parameter in pfile for primary database.

create pfile='/u01/app/oracle/product/11.2.0/db_1/dbs/initprim.ora' from spfile;

vi /u01/app/oracle/product/11.2.0/db_1/dbs/initprim.ora

$ mkdir -p /u01/app/oracle/admin/stand/adump
$ mkdir -p /u01/app/oracle/flash_recovery_area/stand/
$ chmod 775 -Rf /u01

Configure .bash_profile
[oracle@server2 ~]$ vi .bash_profile

# .bash_profile

# Get the aliases and functions
if [ -f ~/.bashrc ]; then
        . ~/.bashrc

FROM v$archived_log
WHERE sequence# =
(SELECT MAX(sequence#) FROM v$archived_log );

While in the Primary Database, you can check what is the current sequence and what is the pending sequence to be applied.

On primary database

SQL> SELECT
(SELECT name FROM V$DATABASE
) name,
(SELECT MAX (sequence#) FROM v$archived_log WHERE dest_id = 1
) Current_primary_seq,
(SELECT MAX (sequence#)
FROM v$archived_log
WHERE TRUNC(next_time) > SYSDATE - 1
AND dest_id = 2
) max_stby,
(SELECT NVL (
(SELECT MAX (sequence#) - MIN (sequence#)
FROM v$archived_log
WHERE TRUNC(next_time) > SYSDATE - 1
AND dest_id = 2
AND applied = 'NO'
), 0)
FROM DUAL
) "To be applied",
(
(SELECT MAX (sequence#) FROM v$archived_log WHERE dest_id = 1
) -
(SELECT MAX (sequence#) FROM v$archived_log WHERE dest_id = 2
)) "To be Shipped"
FROM DUAL;

NAME      CURRENT_PRIMARY_SEQ   MAX_STBY To be applied To be Shipped
--------- ------------------- ---------- ------------- -------------
PRIM                       17         17             0             0

Finally Test on primary database to check if the datas are being replicated to standby or not
SQL> create user soumya identified by soumya;
SQL>grant connect , resource to soumya;
SQL> conn soumya/soumya
SQL>create table test (id number);
SQL>insert into test values(1);
SQL> /
SQL> /
SQL> commit;

Now on standby database:-
sqlplus soumya/soumya

SQL> select * from test;

        ID
----------
         1
         1

So we can see the datas are applying on standby real time.

How to install Oracle 12C database on RHEL 6.4

Requirements :-

*) For large-scale installation we need to use multicore processors with High availability.
*) Recommended minimum RAM needed for Oracle is 2GB or more.
*) Swap must be enabled double the size of RAM.
*)Disk space must be more than 8GB, its depends on edition which are we going to choose for installing.
*)/tmp directory must have free space more than 1GB for error free installation.
*)Supported Linux operating systems are RHEL, Centos, Oracle.
*)Both x86_64 and i686 packages are required for installation.

Step 1:-Set up Hostname and bind it.

[root@server3 ~]# vi /etc/sysconfig/network
NETWORKING=yes
HOSTNAME=server3.soumya.com

-save & exit(:wq)

[root@server3 ~]$ vi /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.2.104 server3.soumya.com server3

-save & exit(:wq)

Step 2:-Disable firewall and put selinux on permissisve or disabled mode.
[root@server3 ~]$ service iptables stop
[root@server3 ~] service iptables save

[root@server3 ~]# cat /etc/sysconfig/selinux

# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
# enforcing - SELinux security policy is enforced.
# permissive - SELinux prints warnings instead of enforcing.
# disabled - No SELinux policy is loaded.
SELINUX=disabled
# SELINUXTYPE= can take one of these two values:
# targeted - Targeted processes are protected,
# mls - Multi Level Security protection.
SELINUXTYPE=targeted

**Remeber you need to restart the server for the changed selinux settings to put on effect.

Step 3:-Install the required packages using YUM

# From Public Yum
yum install binutils -y
yum install compat-libcap1 -y
yum install compat-libstdc++-33 -y
yum install compat-libstdc++-33.i686 -y
yum install gcc -y
yum install gcc-c++ -y
yum install glibc -y
yum install glibc.i686 -y
yum install glibc-devel -y
yum install glibc-devel.i686 -y
yum install ksh -y
yum install libgcc -y
yum install libgcc.i686 -y
yum install libstdc++ -y
yum install libstdc++.i686 -y
yum install libstdc++-devel -y
yum install libstdc++-devel.i686 -y
yum install libaio -y
yum install libaio.i686 -y
yum install libaio-devel -y
yum install libaio-devel.i686 -y
yum install libXext -y
yum install libXext.i686 -y
yum install libXtst -y
yum install libXtst.i686 -y
yum install libX11 -y
yum install libX11.i686 -y
yum install libXau -y
yum install libXau.i686 -y
yum install libxcb -y
yum install libxcb.i686 -y
yum install libXi -y
yum install libXi.i686 -y
yum install make -y
yum install sysstat -y
yum install unixODBC -y
yum install unixODBC-devel -y

Step 4:- Change the kernel parameters .
Add or amend the following lines in the "/etc/sysctl.conf" file.

[root@server3 ~]# vi
fs.file-max = 6815744
kernel.sem = 250 32000 100 128
kernel.shmmni = 4096
kernel.shmall = 1073741824
kernel.shmmax = 4398046511104
net.core.rmem_default = 262144
net.core.rmem_max = 4194304
net.core.wmem_default = 262144
net.core.wmem_max = 1048576
fs.aio-max-nr = 1048576
net.ipv4.ip_local_port_range = 9000 65500

-save & exit(:wq)

Run the following command to change the current kernel parameters.

[root@server3 ~]# /sbin/sysctl -p

Add the following lines to the "/etc/security/limits.conf" file.

[root@server3 ~]#vi /etc/security/limits.conf
oracle soft nofile 1024
oracle hard nofile 65536
oracle soft nproc 16384
oracle hard nproc 16384
oracle soft stack 10240
oracle hard stack 32768

-save & exit(:wq)

Step 5:-Create required groups and users.

[root@server3 ~]#groupadd -g 520 oinstall
[root@server3 ~]#groupadd -g 521 dba
[root@server3 ~]#groupadd -g 522 oper
[root@server3 ~]#useradd -u 520 -g oinstall -G dba,oper oracle
[root@server3 ~]# passwd oracle
Changing password for user oracle.
New password: *****

Add the following lines to the "/etc/security/limits.d/90-nproc.conf" file.

[root@server3 ~]#vi /etc/security/limits.d/90-nproc.conf
# Change number of process
* soft nproc 1024
# To this
* nproc 16384
-save & exit(:wq)

Step 6:- Create required directories and assign them proper permission / ownerships.

[root@server3 ~]# mkdir -p /u01/app/oracle/product/12.1.0.2/db_1
[root@server3 ~]# chown -Rf oracle:oinstall /u01
[root@server3 ~]# chmod -Rf 775 /u01

Step 7:-Configure bash profile for oracle user.

[root@server3 ~]#vi /home/oracle/.bash_profile
# .bash_profile

# Get the aliases and functions
if [ -f ~/.bashrc ]; then
. ~/.bashrc
fi

# User specific environment and startup programs

PATH=$PATH:$HOME/bin
export TMP=/u01/tmp
export TMPDIR=$TMP
export ORACLE_HOSTNAME=server3.soumya.com
export ORACLE_UNQNAME=ora12c
export ORACLE_BASE=/u01/app/oracle
export ORACLE_HOME=$ORACLE_BASE/product/12.1.0.2/db_1
export ORACLE_SID=ora12c
export PATH=/usr/sbin:$ORACLE_HOME/bin:$PATH
export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib:/usr/lib64
export CLASSPATH=$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib

-save & exit(:wq)

Step 7:-Now switch to the directory where the installation file exists extract it.

[root@server3 ~]# cd /u01/
[root@server3 u01]# ls -ltr
total 2625116
-rwxrwxr-x 1 oracle oinstall 1673544724 Mar 1 21:57 linuxamd64_12102_database_1of2.zip
-rwxrwxr-x 1 oracle oinstall 1014530602 Mar 2 19:14 linuxamd64_12102_database_2of2.zip
drwxr-xr-x 4 oracle oinstall 4096 Mar 6 16:22 app

Unzip the installation files.
[root@server3 ~]#unzip linuxamd64_12102_database_1of2.zip
[root@server3 ~]#unzip linuxamd64_12102_database_2of2.zip

Step 8.Now Open X-Manager and start the installation.
*For x-manager make sure "xterm, xorg" packages are installed.

From Xmanager console:-
[root@server3 ~]#su - oracle
[oracle@server3 u01]$ cd database/
[oracle@server3 database]$ ls -ltr
total 36
-rwxrwxr-x 1 oracle oinstall 500 Feb 7 2013 welcome.html
-rwxrwxr-x 1 oracle oinstall 8533 Jul 7 2014 runInstaller
drwxrwxr-x 2 oracle oinstall 4096 Jul 7 2014 rpm
drwxrwxr-x 2 oracle oinstall 4096 Jul 7 2014 sshsetup
drwxrwxr-x 2 oracle oinstall 4096 Jul 7 2014 response
drwxrwxr-x 14 oracle oinstall 4096 Jul 7 2014 stage
drwxrwxr-x 4 oracle oinstall 4096 Mar 6 14:57 install

[oracle@server3 database]$sh runInstaller
In installation window
Step 1 :-Configure security updates => Untick the option "I wish to receive security updates via My oracle support"
Step 2 :-Installation option => Select Create & configure Database.(Incase if you want to configure database choose install database software only )
Step 3 :-System Class => Select Server Class.
Step 4 :-Grid installation option => Select Single instance database installation.
Step 5 :-Install Type => Select Typical install
Step 6 :-Typical installation =>
Make sure at this step we have following paths selected
Oracle_Base =/u01/app/oracle
Software location=/u01/app/oracle/product/12.1.0.2/db_1
Storage type= File system
Database file location=/u01/app/oracle/oradata
OSDBA Group=dba
Global database name=ora12c
Password=provide password
Select option Pluggable Database name=pdbora12c

Step 7 :- It should not make any issue regarding packages or other checks.
Step 8 :- Install.
While the installation is going on it will ask to run following two scripts from root user.
/u01/app/oracle/product/12.1.0.2/db_1/root.sh
/u01/app/oraInventory/oraInstroot.sh

The whole process would take some time..

[oracle@server3 ~]$ sqlplus / as sysdba

How to Enable and Disable Database Options in oracle 11g

Installation of Oracle Database 11g Release 2 Software installs all the licensable database options. Though installed, not all the licensable database options are enabled by default.
During installation, installer gives an option for users to enable the licensable database options that are not enabled in a default installation.

SQL> SET LINESIZE 200
SQL> select * from v$option where value ='FALSE';
PARAMETER                                                         VALUE
---------------------------------------                       --------------------------------------
Real Application Clusters                                        FALSE
Automatic Storage Management                            FALSE
Oracle Label Security                                               FALSE
Real Application Testing                                        FALSE

So we see the disabled options are listed above.

To enable an option lets say "Real Application Testing" we would follow the following process.

Step 1:-Stop the database, Database Control console process, and listener.

SQL> shut immediate;
Database closed.
Database dismounted.
ORACLE instance shut down.

[oracle@configsrv2 ~]$ emctl stop dbconsole
[oracle@configsrv2 ~]$ lsnrctl stop

Step 2:-
[oracle@configsrv2 ~]$ cd $ORACLE_HOME/rdbms/lib
[oracle@configsrv2 ~]$ make -f ins_rdbms.mk rat_on ioracle
After hitting the above command it would take some time as this would enable the Real Application Testing option for the database.

Step 3:-
Once the execution of the above command is done ; we need to start the database, listener and Database Control console process.
[oracle@configsrv2 ~]$ lsnrctl start
SQL> startup
SQL> select * from v$option where parameter='Real Application Testing';

PARAMETER                                                        VALUE
---------------------------------------------------------------- ----------------------------------------------------------------
Real Application Testing                                         TRUE

To disable a certain option:-
SQL> select * from v$option where value ='TRUE';

PARAMETER                                                        VALUE
---------------------------------------------------------------- ----------------------------------------------------------------
Partitioning                                                     TRUE
Objects                                                          TRUE
Advanced replication                                             TRUE
Bit-mapped indexes                                               TRUE
Connection multiplexing                                          TRUE
Connection pooling                                               TRUE
Database queuing                                                 TRUE
Incremental backup and recovery                                  TRUE
Instead-of triggers                                              TRUE
Parallel backup and recovery                                     TRUE
Parallel execution                                               TRUE

Here lets disable Partitioning in our database

Step 1:-
So, Stop the database, Database Control console process, and listener.

[oracle@configsrv2 ~]$ lsnrctl stop
[oracle@configsrv2 ~]$ emctl stop dbconsole
SQL> shut immediate;
Database closed.
Database dismounted.
ORACLE instance shut down.

Step 2:-
[oracle@configsrv2 ~]$ cd $ORACLE_HOME/rdbms/lib
[oracle@configsrv2 ~]$ make -f ins_rdbms.mk part_off ioracle
After hitting the above command it would take some time as this would enable the Partitioning option for the database.

Step 3:-
Once the execution of the above command is done ; we need to start the database, listener and Database Control console process.
[oracle@configsrv2 ~]$ lsnrctl start
SQL> startup
SQL> select * from v$option where parameter='Partitioning';

PARAMETER                                                        VALUE
---------------------------------------------------------------- ----------------------------------------------------------------
Partitioning                                                     FALSE

So we can see the option Partitioning has been disabled for the database.

Here is the list of database options and switches:
Database Option                    ON            OFF
Data Mining                        dm_on        dm_off
Data Mining Scoring Engine        dmse_on        dmse_off
Database Vault                    dv_on        dv_off
Label Security                    bac_on        lbac_off
Partitioning                    part_on        part_off
Real Application Clusters        rac_on        rac_off
Spatial    s                        do_on        sdo_off
Real Application Testing        rat_on        rat_off
OLAP                            olap_on        olap_off
Automatic Storage Management    asm_on        asm_off
Context Management Text            ctx_on        ctx_off

cd /etc/pki/rpm-gpg
rpm --import RPM-GPG-KEY-CentOS-6

#yum install postgresql94-server

# service postgresql-9.4 initdb
or
# service postgresql initdb

# chkconfig postgresql-9.4 on

Step 3:-Start postgresql:-
[root@infosystem ~]# service postgresql-9.4 start
Starting postgresql service: [ OK ]

Check status of postgresql:-
[root@infosystem ~]# service postgresql status
postmaster (pid 4260) is running...

Step 4:- Log into postgre
#su - postgres
$ psql

To create a user:-
postgres=# CREATE USER soumya WITH password 'redhat';
CREATE ROLE

To check version:-
SELECT version ();

To change postgres password:-
postgres=# \password postgres
Enter new password:
Enter it again:

To create a table:-
postgres=#CREATE TABLE COMPANY(
ID INT PRIMARY KEY NOT NULL,
NAME TEXT NOT NULL,
AGE INT NOT NULL,
ADDRESS CHAR(50),
SALARY REAL
);

To view created tables:-
postgres=#\d

List of relations

: postgres=CTc/postgres
template1 | postgres | UTF8 | en_US.UTF-8 | en_US.UTF-8 | =c/postgres
: postgres=CTc/postgres

To drop a database:-
postgres=# drop database mydb;
DROP DATABASE

To backup all database:-
pg_dumpall > all.sql

To verify the backup:-
bash-4.1$ grep "^[\]connect" all.sql
\connect postgres
\connect mydb1
\connect postgres
\connect template1

To create a table under a schema:-
create schema soumya;
set search_path to soumya;
create table foo (id int);

To backup a particular db:-
pg_dump kmi > kmi.sql[mydb1 is db name for which i'm taking the backup]

SELECT * FROM pg_stat_activity WHERE datname='mydb1';

Restore all the postgres databases

$ psql -f alldb.sql

Restore a single postgres table:-

$ psql -f kmi.sql kmi

How to install MongoDB on RHEL 6

How to install MongoDB on RHEL 6:-

Os version _ Rhel 6.4
MongoDB Version:-2.6.7

Step:1 System Login as root user. We are checking system OS type and system bits type.

# uname –a
Linux server1.soumya.com 2.6.32-358.el6.x86_64 #1 SMP Tue Jan 29 11:47:41 EST 2013 x86_64 x86_64 x86_64 GNU/Linux

# cat /etc/issue
Red Hat Enterprise Linux Server release 6.4 (Santiago)
Kernel \r on an \m

Step:2 Now we are creating a yum repo file .like /etc/yum.repos.d/mongodb.repo

# vi /etc/yum.repos.d/mongodb.repo
[mongodb]
name=mongodb Repository
baseurl=http://downloads-distro.mongodb.org/repo/redhat/os/x86_64
gpgcheck=0
enabled=1

--save & exit(:wq)

Step:3 Now we install mongodb client and server using yum

# yum install mongo-*

If you face any error while installing the rpms do the following
# yum erase mongo*
yum shell
> install mongodb-org
> remove mongo-10gen
> remove mongo-10gen-server
> run

Step:4 Now we can configure and basic setting in Mongodb Database Server

# vi /etc/mongod.conf
logappend=true
logpath=logpath=/var/log/mongodb/mongod.log
port=27017
dbpath=/var/lib/mongo
smallfiles = true
:wq

Step:5 Start Mongodb Server

# /etc/init.d/mongod start
# chkconfig mongod on

Open another terminal and type
#mongo

Show all database:-
>show dbs

Define a database name as soumya:-
>use soumya

then to check your current db name:-
>db

To add the created db in dblist we need to add collection in this database.For instance, create a document in a customers collection like this:
db.customers.save({"firstName":"Alvin", "lastName":"Alexander"})

Next, verify that your document was created with this command:
db.customers.find()

Now check your db name:-
>show dbs

Now to add a new user in a db:-
>use pizza
>db.createUser( { user: "soumya",
pwd: "redhat2",
roles: [ "readWrite", "dbAdmin" ]
} )

To check all the users in your current db:-
>show users
or
db.system.users.find()

To drop the database pizzas:-
use pizzas;
>db.dropDatabase()

To check current version:-
db.version()

Done..
