Solution is successfully on Nokia Lumia 520 (Handset) and Idea is the Mobile Operator

Go to Settings
->  access point
-> Add (you may be confused that there is already Idea, don't worry click on Add)
Enter only 2 field
-> Connection Name (you can write Idea)
->Internet Access point name(APN) - Enter Internet

The solution turned out to be successful without a reboot

Different ways to login to the Database

1.

$sqlplus //from OS Prompt

enter username:

enter password:

SQL>show user //from SQL Prompt, shows the user currently 

2.

$sqlplus hr //from OS prompt logs into the user asking for password

Enter password

3.

$sqlplus hr/password@orcl //from OS prompt using the user name and pasword along with the database you want to login

Pre-Installation Configurations: Meeting the software requirements:

Once all hardware requirements are verified, we will proceed with further configuration.

Make sure that there is an entry in /etc/hosts file for your machine like this:


[IP-address]  [fully-qualified-machine-name]  [machine-name]
/*
 Where "fully-qualified-machine-name" is your "machine_name"."domain_name"
*/

--------------------------------------------------------------------------------------------------------------

Next we need to adjust the Linux Kernel Parameters to support Oracle.
Open /etc/sysctl.conf and add the following lines:

sysctl is an interface that allows you to make changes to a running Linux kernel. With /etc/sysctl.conf you can configure various Linux networking and system settings such as:

1. Limit network-transmitted configuration for IPv4
2. Limit network-transmitted configuration for IPv6
3. Turn on execshield protection
4. Prevent against the common 'syn flood attack'
5. Turn on source IP address verification
6. Prevents a cracker from using a spoofing attack against the IP address of the server.
7. Logs several types of suspicious packets, such as spoofed packets, source-routed packets, and redirects.

# Oracle settings
fs.aio-max-nr = 1048576
fs.file-max = 6815744
kernel.shmall = 2097152
kernel.shmmax = 536870912
kernel.shmmni = 4096
kernel.sem = 250 32000 100 128

net.ipv4.ip_local_port_range = 9000 65500 // #Increase system IP port limits

net.core.rmem_default = 262144 //# increase Linux auto tuning TCP buffer limits
net.core.rmem_max = 4194304
net.core.wmem_default = 262144
net.core.wmem_max = 1048586

# TCP and memory optimization 
# increase TCP max buffer size setable using setsockopt()

net.ipv4.tcp_wmem = 262144 262144 262144
net.ipv4.tcp_rmem = 4194304 4194304 4194304

--------------------------------------------------------------------------------------------------------------

Note: You may find the parameters mentioned above already present in the /etc/sysctl.conf file. If they have a value lower then mentioned above then make sure you change it, but if they have a larger value then perhaps its safe to leave it as is.


-- Make the kernel parameters changes effective immediately:
# /sbin/sysctl -p

-- Verify the parameters are changed or not?
# /sbin/sysctl -a | grep name_of_kernel_parameter -- e.g. shmall


Now setup User that we will use as Oracle owner and the groups that it will need for installing and managing Oracle.


/usr/sbin/groupadd oinstall
/usr/sbin/groupadd dba
/usr/sbin/groupadd oper
/usr/sbin/useradd -g oinstall -G dba,oper oracle
/usr/bin/passwd oracle

-----------------------------------------------------------------------------------------------------------------------------------------

Create directories where the Oracle Software and database will be installed.

mkdir -p /u01/app/oracle/product/11.2.0/db_1
chown -R oracle:oinstall /u01
chmod -R 0775 /u01

/*
 The above directory structure is designed to comply with OFA (Oracle Flexible Architecture) i.e. a directory structure to
 support multiple oracle software installations.

 ORACLE_BASE=/u01/app/oracle
 -- Base directory for all oracle installations.

 ORACLE_HOME=ORACLE_BASE/product/11.2.0/db_1 -- 11.2.0 installation 1.
 ORACLE_HOME=ORACLE_BASE/product/11.2.0/db_2 -- 11.2.0 installation 2.
 ORACLE_HOME=ORACLE_BASE/product/10.2.0/db_1 -- 10.2.0 installation 1.

 and so on....
*/

-----------------------------------------------------------------------------------------------------------------------------------------


-----------------------------------------------------------------------------------------------------------------------------------------
http://ss64.com/bash/limits.conf.html

Now set the shell limits for the user Oracle.
Open /etc/security/limits.conf and add these lines.






oracle           soft    nproc   2047
oracle           hard    nproc   16384
oracle           soft    nofile  1024
oracle           hard    nofile  65536





The syntax of the lines:

<domain> <type> <item> <value>

 

hard

for enforcing hard resource limits. These limits are set by the superuser and enforced by the Kernel. The user cannot raise his requirement of system resources above such values.

 

soft

for enforcing soft resource limits. These limits are ones that the user can move up or down within the permitted range by any pre-exisiting hard limits. The values specified with this token can be thought of as default values, for normal system usage.

Where "nproc" is the maximum number of processes available to the user and "nofiles" is the number of open file descriptors.

PAM - Pluggable Authentication Modules

Open /etc/pam.d/login and add the following line if it is already not there.

session    required     pam_limits.so

------------------------------------------------------------------------------------------------------------------------------------------

Disable secure linux by editing the /etc/selinux/config file, making sure the SELINUX flag is set as follows:

SELINUX=disabled

------------------------------------------------------------------------------------------------------------------------------------------

If you leave SELINUX=enforcing then you may get an error later while starting sqlplus:
sqlplus: error while loading shared libraries:
/usr/lib/oracle/default/client64/lib/libclntsh.so.11.1: cannot restore segment
prot after reloc: Permission denied

Now we need to make sure we have all necessary packages for Oracle. Put your Linux Media into DVD and go to the "Server" directory.

NOTE: If you are using RHEL5 DVD then you should find them all in the "Server" directory in your DVD. And if you don't find one there you may download it from the Linux vendor's Web site.
If you have your Linux distribution in 3 CDs then these will be scattered on all three CDs in the Server directory on all CDs.

Allow the user oracle to use X server, which it will need to run Oracle Universal Installer.

------------------------------------------------------------------------------------------------------------------------------------------

# xhost +SI:localuser:oracle

Now switch to the user oracle.

# su - oracle

-- Let's see which shell is being used by the user Oracle.
$ echo $SHELL
/bin/bash

# to change your shell use $ chsh -s /bin/tcsh




------------------------------------------------------------------------------------------------------------------------------------------

If the returned shell is bash then open ~/.bash_profile and add these lines:

# Oracle settings
TMP=/tmp; export TMP
TMPDIR=$TMP; export TMPDIR

# If /tmp doesn't have 1G space free then you can workaround it by
# pointing the variables TMP AND TMPDIR to a location where you have
# sufficient space.

ORACLE_HOSTNAME=ora11g.home.com; export ORACLE_HOSTNAME
ORACLE_BASE=/u01/app/oracle; export ORACLE_BASE

LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib;
export LD_LIBRARY_PATH

export CLASSPATH


if [ $USER = "oracle" ]; then
   if [ $SHELL = "/bin/ksh" ]; then
     ulimit -p 16384
     ulimit -n 65536
   else
     ulimit -u 16384 -n 65536
   fi
fi

umask 022

------------------------------------------------------------------------------------------------------------------------------------------

If using C shell then open ~/.login and add these lines:

# Oracle settings
setenv TMP=/tmp
setenv TMPDIR=$TMP

# If /tmp doesn't have 1G space free then you can workaround it
# by pointing the variables TMP AND TMPDIR to a location where you
# have sufficient space. Oracle will then use this directory for
# temporary files.

setenv ORACLE_HOSTNAME ora11g.home.com
setenv ORACLE_BASE /u01/app/oracle
setenv ORACLE_HOME $ORACLE_BASE/product/11.2.0/db_1
setenv ORACLE_SID ora11g
setenv ORACLE_TERM xterm
setenv PATH /usr/sbin:$PATH
setenv PATH $ORACLE_HOME/bin:$PATH

setenv LD_LIBRARY_PATH $ORACLE_HOME/lib:/lib:/usr/lib
setenv CLASSPATH $ORACLE_HOME/JRE:$ORACLE_HOME/jlib
setenv CLASSPATH $CLASSPATH:$ORACLE_HOME/rdbms/jlib

if ( $USER == "oracle" ) then
      limit maxproc 16384
      limit descriptors 65536
endif

umask 022
------------------------------------------------------------------------------------------------------------------------------------------

Now run the following command to make these changes effective in the current session of user oracle.

-- for bash shell
$ source ~/.bash_profile
-- for C shell
$ source ~/.login

------------------------------------------------------------------------------------------------------------------------------------------

------------------------------------------------------------------------------------------------------------------------------------------
Install Oracle 11g Release 2 on RHEL 5:

The environment is ready for oracle installation. Its time to prepare the oracle installation media now.
Download or Copy the oracle media to the oracle user home directory i.e. /home/oracle.
Once Download/Copy is done unzip the media as follows:

$ cd /home/oracle
$ ls
linux_11gR2_database_1of2.zip  linux_11gR2_database_2of2.zip
$
$ unzip linux_11gR2_database_1of2.zip
$ unzip linux_11gR2_database_2of2.zip

Once the unzip is finished go to the "database" directory unzipped in the previous step and start the Oracle Universal Installer.

$ cd /home/oracle/database/
$ ./runInstaller

The OUI (Oracle Universal Installer) should start and you should see following screens in the order given below:

1. Provide your email address and Oracle support password to get security updates from Oracle.

    Configure Security Updates

2. Installation options like creating a database, installing oracle software only or upgrading the database. Select "Create and configure a database".

    Installation Options

3. Choose the system class here. Select "Server Class" it provides more advanced options.

    System Class

4. Choose from creating a single node installation or RAC.

    Node Selection

5. Choose your installation Typical or Advanced. We will go with typical at this moment.

    Install Type

6. If you choose typical install in previous screen, then you will see this page for Install Configurations. Provide Oracle software installation location, database files location and administrator password etc.

    Typical Install Configurations

7. Specify the Oracle install inventory location and Operating system group "oinstall".

    Create Inventory

8. Now all prerequisite checks will be performed here and if every thing is ok you will be moved to the install summary page. You can hit the "Back" button and come back to see the status of all the checks performed.

    Prerequisite Checks

9. Installation Summary page. Hit "Finish" to start the Installation.

    Install Summary

10. Installation Progress. This will take several minutes and it will automatically invoke Database COnfiguration Assistant to create a database.

    Installation Progress

11. Database Configuration Assistant invoked by the installer.

    Database Configuration Assistant

12. Once DBCA has finished creating the database, it will show a page like this. It is a summary of the database that has just been created.

    Database Creation Summary

13. As a last step you will be asked to execute some configuration scripts as root.

    Execute Configuration Scripts
