How to Login as Sys Oracle Sql Developer

In this tutorial, nosotros volition learn how to create a new user and connectedness in SQL developer. Nosotros will besides larn how to unlock Hour account and understand more about Hour schema.

This commodity is divided in iii parts:

1. Create a New Connection for SYS user
2. Create a New Connection for 60 minutes User
3. Create a New User and Connection in SQL programmer

Create a new Database connection for SYS user

This is the get-go thing that we need to practice later installing SQL programmer.

Once we have installed Oracle database and SQL developer on our system, we need to create a connection using SQL programmer to connect with Oracle database. We tin use both SQL developer and Command Prompt to collaborate with the database.

When we install Oracle database, information technology comes with some predefined users like STS, SCOTT, SYSTEM, HR etc. SYS user is the one which has all the administrative privileges. Nosotros simply login to the database using this user when we need to perform administrative tasks.

Since, SYS and SYSTEM users are already created when we install Oracle Database, we just need to create a connectedness in SQL developer to connect with the database.

Pace i: Open up the New Connection Window

Click on the 'Green Plus' Sign under Connections on the left to open up New Connection Window. This screen opens up.

Here,

• Username is SYS and Password is what you gave at the time of Oracle Database installation. In our instance,
• Proper noun – System ( You tin give any proper noun, but nosotros give information technology as System for quick reference )
• username – SYS
• password -system
• Office – SYSDBA
• Connection Blazon – Basic

Stride 2: Check hostname, port and SID in tsnames.ora file

For hostname, port and SID y'all can once check the tsnames.ora file in the Oracle Installation Directory.

The path of this file on my machine is >>

C:\oraclexe\app\oracle\product\xi.ii.0\server\network\ADMIN\tsnames.ora

Yous can also search for this in your Oracle Installation Directory.

Open this file in Notepad++ or any other text editor and this will give you lot the hostname, port and SID. Employ this information while creating any new user or connectedness in SQL developer. In most cases it's default, simply in some cases the SID might be different

Later on this click on Examination and and so Salve to create a new database connection for SYS user in SQL developer.

Create a New Database connection for HR User

HR is other predefined user which comes Hr schema. HR schema consists of some database tables which we use for oracle training. These tables are generally used for learning Oracle and nosotros perform all SQL queries on these practice tables.

Only like SYS user, 60 minutes user is as well automatically created when we install Oracle Database. We just need to create a new connexion for this HR user in SQL developer.

Step 1: Open the new connection window in SQL developer

Just like earlier, click on the 'Green Plus Sign' under connections to open the New connexion window.

Enter the following data:

• Name- hour
• username -60 minutes
• password -hr
• Role – Default
• Connection Blazon- Basic

Hostname, Port and SID is the same that we used while creating the SYS user connection. You can as well check it in tsnames.ora file.

As you tin can see, nosotros received the ORA-28000 Error saying the account is locked. This happens because sometimes we forget to unlock these accounts at the fourth dimension of Oracle Database Installation. We can unlock this account by writing a simple two line SQL query.

Footstep ii: Unlock the Hr account in SQL Developer

For this, nosotros utilize the SQL command Line Tool. Just search for SQL command Line tool in your Commencement Menu every bit this tool is as well installed when we install the Oracle Database.

SQL Developer is a GUI ( Graphical User Interface) tool which allows u.s. to work with the database using just our mouse and we get to see and edit the information in tables as we exercise in Excel. But SQL Command Line Tool is simply used for writing queries and does non offering any graphical interface to interact with information in the database.

Let'due south use SQL control Line tool to write this 2 queries, one after other

connect arrangement/arrangement every bit sysdba;

alter user hr identified by hr business relationship unlock;

The first line is used for connecting with database using arrangement username and password.

The second line is used for altering the hr user account and instructing Oracle to Unlock information technology.

User is altered.

Step 3: Create Hr connection in SQL Developer

Repeat Step ane and this time as y'all can run into, it shows success.

Click on Examination > Save and then login to this account using

• username- hour
• countersign -hour

HR Schema

All relational objects like Tables, Views, Functions etc. inside a database are owned by a specific user. These objects together are referred to as Schema.

Every bit we already saw, SYS, SCOTT, Organization, HR are some of the users which are created at the time of Oracle Database installation. Each user has its ain schema or relational objects associated with information technology.

60 minutes schema consists of seven tables and a view and procedure. These are exercise tables with dummy data which reflect data used in a existent organisation.

We use these tabular array to perform operations and manipulate information within these table as per our requirements and to learn Oracle SQL.

Create a New User and Connection

SYS and HR were the users which come preinstalled. Let's see how to create a brand new user using SQL developer.

Step ane: Login to SYS account and Create a New User

For creating a new user, we need to login to the SYS business relationship using username and countersign.

Here, we have the option of simply writing a query to create a new user or to use SQL Developer interface to create new user.

Footstep 2: Open the SYS User schema and go to > Other Users > Create User

Pace 3: Give username and password

Give any name you wish, just brand sure it does non disharmonize with the name of any user that comes preinstalled with Oracle.

• Default Tablespace – Users
• Temporary Tablespace – Temp

Footstep 4 : Grant Privileges

Grant Connect, DBA and Resource Privileges to this new user.

Pace 5 : Grant Quota for Tablespace

Users > Unlimited

Click Apply and this new user has been created.

Stride 6: Create a New Connection for this New User

Alternate Method to Create New User

We tin can also create new user and connection using few simple queries.

Step 1:

Let's directly create the user by using SQL queries by logging into the SYS user business relationship.

CREATE USER 'obama' identified by 'obama';

Pace 2:

Type this query to bank check, if the account status. If its locked, we may go error. Replace the username with username that you have given.

SELECT * FROM dba_users WHERE username ='obama';

Step 3 :

Create new connexion past clicking on 'green plus sign' in SQL developer.

As you can come across, nosotros are getting the ORA-01045 mistake every bit we accept non granted privileges to user.

Footstep four:

Permit's grant all privileges to new user:

grant privileges to obama;

Finally, Nosotros have created the new user and connection.

Permit'due south check if everything is working fine by writing 1 simple query afterwards logging into new user account we just created:

Everything is working fine.

In this tutorial, we learned how to create a new user and connexion in SQL programmer.
