Prerequisites:-

Download Oracle 11gR2

Steps:-

1. Installing Dependencies
To install dependencies, run

sudo apt-get update

sudo apt-get install gcc make binutils gawk x11-utils rpm build-essential libaio1 libaio-dev libmotif4 libtool expat alien ksh pdksh unixODBC unixODBC-dev sysstat elfutils libelf-dev binutils lesstif2 lsb-cxx libstdc++5

2. We need to create some softlinks to start the installation. To do so run the following commands,

sudo ln -sf /bin/bash /bin/sh

sudo ln -s /usr/bin/awk /bin/awk

sudo ln -s /usr/bin/rpm /bin/rpm

sudo ln -s /usr/bin/basename /bin/basename

sudo ln -s /usr/lib/i386-linux-gnu/libpthread_nonshared.a /usr/lib/libpthread_nonshared.a

sudo ln -s /usr/lib/i386-linux-gnu/libc_nonshared.a /usr/lib/libc_nonshared.a

sudo ln -s /lib/i386-linux-gnu/libgcc_s.so.1 /lib/libgcc_s.so.1

sudo ln -s /usr/lib/i386-linux-gnu/libstdc++.so.6 /usr/lib/libstdc++.so.6

3. Also we need to add oracle user and oinstall, dba, nobody group. Run following commands,

sudo addgroup oinstall

sudo addgroup dba

sudo addgroup nobody

sudo usermod -g nobody nobody

sudo useradd -g oinstall -G dba -p password -d /home/oracle -s /bin/bash oracle

sudo mkdir /home/oracle

sudo chown -R oracle:dba /home/oracle

4. We need to do changes in start-up script, run following commands as root

mkdir /etc/rc.d

for i in 0 1 2 3 4 5 6 S

do ln -s /etc/rc$i.d /etc/rc.d/rc$i.d

done

5. Now we will create the directory for installation, and changes it owner to oracle. Run following commands to do the same

sudo mkdir -p /u02/oradata/MYDB

sudo chown -R oracle:dba /u01

6. We also need to modify the kernel parameter, to do so run following commands as root

echo "#">> /etc/sysctl.conf

echo "# Oracle 11gR2 entries">> /etc/sysctl.conf

echo "fs.aio-max-nr=1048576" >> /etc/sysctl.conf

echo "fs.file-max=6815744" >> /etc/sysctl.conf

echo "kernel.shmall=2097152" >> /etc/sysctl.conf

echo "kernel.shmmni=4096" >> /etc/sysctl.conf

echo "kernel.sem=250 32000 100 128" >> /etc/sysctl.conf

echo "net.ipv4.ip_local_port_range=9000 65500" >> /etc/sysctl.conf

echo "net.core.rmem_default=262144" >> /etc/sysctl.conf

echo "net.core.rmem_max=4194304" >> /etc/sysctl.conf

echo "net.core.wmem_default=262144" >> /etc/sysctl.conf

echo "net.core.wmem_max=1048586" >> /etc/sysctl.conf

echo "kernel.shmmax=1073741824" >> /etc/sysctl.conf

7. Note: kernel.shmmax = max possible value, e.g. size of physical memory in bytes. In my case machine is having 2GB so we are specifying 1GB. Adjust the parameter as per your configuration

Load new kernel parameters, by running following,

sudo sysctl -p

8. We have to change shell configuration, to do the same run following commands as root user,

cp /etc/security/limits.conf /etc/security/limits.conf.original

echo "#Oracle 11gR2 shell limits:">>/etc/security/limits.conf

echo "oracle soft nproc 2048">>/etc/security/limits.conf

echo "oracle hard nproc 16384">>/etc/security/limits.conf

echo "oracle soft nofile 1024">>/etc/security/limits.conf

echo "oracle hard nofile 65536">>/etc/security/limits.conf

9. Download Oracle 11g R2 database from Oracle Download Center for linux.

I have downloaded both the zip in /home/oracle. We need to extract both the zip to start the installation. To unzip run,

cd /home/oracle

unzip linux_11gR2_database_1of2.zip

unzip linux_11gR2_database_2of2.zip

10. Now we will start the installation. You can start the installation from /home/oracle/database.
Login as a oracle user.

su oracle

11. Go to the binaries and start the installation as a oracle user,

cd /home/oracle

chmod 777 -R database

cd database

./runInstaller -ignoreSysPrereqs

12. Next we go though the installation (I don’t have the “Oracle Support Password” so just skip in here):

In Selection Installation Option, choose Create and configure a database:

In System Class, choose Server Class (we hope to give a full control during installation):

In Node Selection, choose Single instance database installation:

In Select Install Type, choose Advanced install:

In Select Product Languages, I choose to install English language:

In Select Database Edition, I choose Enterprise Edition:

In Specify Installation Location, it should default as below:

Oracle Base: /u02/oradata/MYDB

Sofeware Location: /u02/oradata/MYDB/product/11.2.0/dbhome_1

13. In Create Inventory, it should default as below:

Inventory Directory: /u02/app/oraInventory

oraInventory Group Name: oinstall

14. In Select Configure Type, choose General Purpose / Transaction Processing:

(IMPORTANT!) In Specify Database Identifiers, configure as below:

Global database name: mydb.asaptp.com

Oracle Service Identifier (SID): MYDB

15. In Specify Configuration Options, configure as below:

Memory -> Enable Automatic Memory Management: TRUE

Character sets: Use Unicode (AL32UTF8)

16. In Specify Management Options, choose Use Database Control for database management but keep other else empty:

In Specify Database Storage Options, choose File System where:

Specify database file location: /u02/oradata/MYDB/oradata

In Specify Recovery Options, choose Do not enable automated backups:

In Specify Schema Passwords, I am a bit lazy so choose Use the same password for all accounts (don’t do this in production server!):

In Privileged Operating System Groups, confirm as below:

Database Administrator (OSDBA) Group: dba

Database Operator (OSOPER) Group: oinstall

17. In Preform Prerequisite Checks, just simply ignore all warning message (since we are using Debian but not Oracle officially supported OS):

18. Special note for Ubuntu 12.04: If you face error during installation so update as below:

19. When you see the above error, open a new session to the Server and execute the below commands:

export ORACLE_HOME=/u02/oradata/MYDB/product/11.2.0/dbhome_1
sed -i 's/^$\s*\$(MK_EMAGENT_NMECTL)$\s*$/\1 -lnnz11/g' $ORACLE_HOME/sysman/lib/ins_emagent.mk
sed -i 's/^$\$LD \$LD_RUNTIME$ $\$LD_OPT$/\1 -Wl,--no-as-needed \2/g' $ORACLE_HOME/bin/genorasdksh
sed -i 's/^$\s*$$\$(OCRLIBS_DEFAULT)$/\1 -Wl,--no-as-needed \2/g' $ORACLE_HOME/srvm/lib/ins_srvm.mk
sed -i 's/^$TNSLSNR_LINKLINE.*\$(TNSLSNR_OFILES)$ $\$(LINKTTLIBS)$/\1 -Wl,--no-as-needed \2/g' $ORACLE_HOME/network/lib/env_network.mk
sed -i 's/^$ORACLE_LINKLINE.*\$(ORACLE_LINKER)$ $\$(PL_FLAGS)$/\1 -Wl,--no-as-needed \2/g' $ORACLE_HOME/rdbms/lib/env_rdbms.mk

20. Then press Continue and keep going …

21. Now following the instructions and run the following commands with root user:

/u02/app/oraInventory/orainstRoot.sh
/u02/oradata/MYDB/product/11.2.0/dbhome_1/root.sh

22. Confirm with installation progress

23. In previous screen the installer mentioned that we can access Enterprise Manager Database Control URL
from https://localhost.localdomain:1158/em, so now let’s open the browser and test it with following account:

User Name: SYS
Password: your_secret_password
Connect As: SYSDBA

24. login as oracle user root@ubs-desktop:~# su – oracle

25. startup lsnrctl
oracle@ubs-desktop:~$ lsnrctl start

26. startup database
oracle@ubs-desktop:~$ sqlplus sys as sysdba

SQL> startup;

SQL> alter user scott identified by tiger;

SQL> alter user scott account unlock;

SQL> exit

Troubleshoot -EM Daemon is not running

Quite often, the Enterprise Manager Database Control doesn’t work. An error is seen as follows

$ emctl status dbconsole
Oracle Enterprise Manager 11g Database Control Release 11.2.0.1.0

Logs are generated in directory /u02/app/oracle/product/carried-desktop_orcl/sysman/log

FIX:-

Set date/time

SQL>ALTER database SET TIME_ZONE ='Asia/Calcutta';

Run following commands

$ORACLE_HOME/sysman/lib
make -f ins_emagent.mk "agent"
snip ... -lnmemso -lcore11 -lnnz11 ...snip

Still not fixed????

Try running:-

emca -config dbcontrol db -repos recreate
