After DB installation Ensure the following services are running.
1. Oracle service<Instance Name>
2. Oracle listener service

Goto sqlplus enter userid/pwd or userid/pwd@service_name
If the username and pwd is correct, we would be logged into the oracle and will get the SQL Prompt

To Create Table Space:
Create a folder in local drive like BOSE_DBF
Tablespace created.

To Increase the Tablespace Size:
• Increasing the Existing Datafile

Database altered.

Appending additional DATA file to the Tablespace

SQL> alter tablespace kk add datafile 'e:\bose_dbf\bose1.dbf' size 20M;
Tablespace altered.

To create DB user:
SQL> create user <username> identified by <password> default tablespace <Tablespace Name>
Temporary tablespace <Temporary tablespace name>;

SQL> create user bose identified by bose default tablespace bose temporary tablespace temp;
User created.

SQL> show user;

Granting Access to the USER:
SQL> grant create session,imp_full_database to <user name>
SQL> grant create session,imp_full_database to bose;
Grant succeeded.

Granting DBA Access to the USER:
SQL> grant dba to user
SQL> grant dba to bose;
Grant Succeeded

Altering USER:
SQL> alter user bose quota unlimited on <username>;
SQL> alter user bose quota unlimited on bose;
User altered.

Now we will exit from the sys user and will connect our newly created to user to import or export the db objects

SQL>conn bose/bose

Syntax for Import:
• C:\>imp <username>/<password> file=<dumpname.dmp> log=<logfilename.log> full=y
C:\>imp bose/bose file=bose.dmp log=boseimp.log full=y

• C:\>imp <username>/<password> file=<dumpname.dmp> log=<logfilename.log> fromuser=<fromusername> touser=<tousername>

• Before import we need to check the tablespace free space.
INDX -100M

C:\>imp bose/bose file=bose.dmp log=boseimp.log fromuser=hr touser=bose
Import completed successfully with warnings.

After Import Connect to the Respective DB user

Enter username: bose/bose

SQL>@c:\compile – it will compile all the Invalid objects run the compile script atlease 4 times.

Exporting DB user:
C:\> exp <username>/<password> file=<filename.dmp> log=<logname.log>
C:\>exp bose/bose file=bose.dmp log=kk.log
Export terminated successfully without warnings.

Taking full DB Export:
 C:\>exp system/<system pwd> file=<filename.dmp log=logfile.log full=y
C :\> exp system/system file=fulldump.dmp log=fulldump.log full=y

To drop DB user:
SQL> drop user kk cascade;
              User dropped.

To drop DB user object:
Connect to specified Database
SQL> CONN bose/bose
To Drop Tablespace:
SQL> drop tablespace bose including contents;
Tablespace dropped.

SQL> select username from dba_users:
It will display all the username in the DB

SQL> select name from v$database;
It will display the DB name

SQL> select count(*) from user_objects;
           It will display the number of objects in that schema.

Step by Step installation of Oracle Client in Windows 7

I am giving here the complete step by step installation of  Oracle Client 32bit installation in Windows7 64 bit machine environment. If you are planning to install oracle client in windows machine this post will help you install completely.

Step 1: 
Download oracle client software from oracle site and unarchive the zip file and click on setup.exe from the unarchived client folder

Step 2: 
Oracle Universal Installer starts to initiate the installation with the below screen
Step 3:
Actually from here actual only actual installation steps begins. Select the type as per your needs. Here I am having the master database installed in another machine in the network so going with 'Administrator' installation to have a complete installation and features of Oracle Client
Step 4:
Select the languages support you need to be have with this installation. Here I have selected all the languages.
Step 5: 
This step is an important step in Oracle Client Installation. If you are having database installed already in the machine and if you are installing oracle Client also on the same machine then It will select the same path where database is installed automatically.

I suggest always to create a separate folder and Install it in separate place to differentiate database and client easily.
Step 6:
once you clicked with 'Next' button with above screen, we will get the below screen. With this screen we have the button 'Save Response File' to save the installation details in a file and then Click 'Finish'
Step 7:
Once we clicked 'Finish' with above screen installation of client starts and It takes a while to install all the necessary files and details in folder.
Step 8:
After successful completion of installation we will be getting below screen. Just click 'Close' to complete installation.
