How To Install Oracle 21c Express Edition On Windows 11

[Demeter Exekutor]

Im trying to Install Oracle Database 11g express edition. I've used it many times in the past with no problem. Recently my work machine was rebuilt, and while trying to install oracle, on the step that shows TNS port, MTS Port, and HTTP Port, it will not accept the default 1521 port, or any other port I try (I've tried quite a few). Message box says "Port 1521 is in use. Specify a different port number. This port is not in use that I can tell.

Had this same problem. Regardless of what port i put, it would say "port already in use'. Solution was to change to a port known to be open, then click the back button on the installer until you get back to the first installer screen, then continue clicking next. This will install on your specified http port.

The thing is, when you have this screen, try to go back to the beginning of the install wizard,then go next from the beginning to the part "Specify Database Port" and by magical when you insert the same port : you manage to access at the next step.

SQL Express is a free and feature-limited edition of SQL Server that has been being published since the SQL Server 2005 version and it still continues to be published by Microsoft. Nowadays, Microsoft has released the Express edition of SQL Server 2019. We can use this edition for lightweight data-driven mobile, desktop or web applications. However, when we decide to use this edition, the supported features have to be checked in the Editions and supported features of SQL Server 2019. For example, the database size can not exceed 10 GB and the SQL Server Agent feature is not supported by the Express editions. As a result, we must take the limited features into consideration before planning to use the SQL Express Editions.

We can download the express edition of SQL Server 2019 from the Microsoft official web site. On this download page, we can find out the express edition download link. When we click the Download now link, we can begin the download process:

After downloading the setup package, we can start the installation steps. We will right-click the installation file which is named SQL2019-SSEI-Expr.exe and select the Open option in order to start the installation process. In this step, we must make sure that the logged-on user already has the necessary rights to install the programs on the computer. Otherwise, we can face problems during the installation steps:

The Custom installation method offers more advanced installation options so that we can configure the features and other options of the SQL Server installation. We will use the Custom installation method. In the next screen, we will set the path of the setup files to be downloaded and then click the Install button:

After the completion of the download, the SQL Server Installation Center will meet us. In this screen, besides installing the SQL instance, we are able to install SQL Server Reporting Service, SQL Server Management Studio or SQL Server Data Tools and we can also upgrade the installed version of SQL Server.

In the Install Rules screen, the potential issues will be checked by SQL Setup that might be occurred during the installation. We will click the Next button and skip the next step:

At the same time, we can determine the service account of the SQL Server Database Engine and SQL Server Browser. In the Collation tab, we can customize the Server collation option of the SQL Server:

In the Mixed Mode, the SQL Server can be accessed with both Windows authentication and SQL Server authentication. For this installation, we will select the Mixed Mode option, so we will set the password of the sa login of the SQL Server and we will also add a windows login. We can directly add the current windows user to the windows through the Add Current User button:

Tip: If you predict over workload on the TempDB database for your SQL Server, you can change the number of the tempdb files. Microsoft recommended the following rule as a best practice:

After installing the SQL Express, we are able to connect to the SQL Server Database Engine over the SQL Server Management Studio. The following server notation can be used to open a connection to SQL Engine:

In this article, we learned how to install SQL Server Express step by step with details. By following these steps, we can easily complete the installation process of the SQL Server 2019 Express edition.

NetBeans IDE includes built-in support for Oracle Database. You can easily establish a connection from inside the IDE and begin working with the database. This tutorial demonstrates how to use a local installation of Oracle Database 10_g_ Express Edition (Oracle Database XE), a lightweight database that is free to develop, deploy, and distribute.

This tutorial demonstrates how to connect to an Oracle Database XE instance installed on your local system, but the steps can also be applied when you are connecting to a remote instance. If you are connecting to a local instance you need to download and install Oracle Database XE. The installation process is simple and intuitive, but if you have questions, refer to the Oracle Database XE installation guide for your platform.

A common way of interacting with databases is running SQL commands in an SQL editor or by using database management interfaces. For example, Oracle Database XE has a browser-based interface through which you can administer the database, manage database objects, and manipulate data.

Although you can perform most of the database-related tasks through the Oracle Database management interface, in this tutorial we demonstrate how you can make use of the SQL Editor in the NetBeans IDE to perform some of these tasks. The following exercises demonstrate how to create a new user, quickly recreate a table, and copy the table data.

In real life, a database administrator creates custom roles and fine tunes privileges for each role. However, for the purpose of our tutorial, we can use a predefined role, such as CONNECT . For more information about roles and privileges, see Oracle Database Security Guide.

There are several ways to create a table in the database through the NetBeans IDE. For example, you can run an SQL file (right-click the file and choose Run File), execute an SQL Command (right-click the connection node and choose Execute Command) or use the Create Table dialog box (right-click the Tables node and choose Create Table). In this exercise you will recreate a table by using the structure of another table.

In this example, you want the user jim to create a copy of the Departments table in his schema by recreating the table from the hr database. Before you create the table you will need to disconnect from the server and log in as user jim .

Right-click the Locations table node and choose View Data to see the table contents. You will see the contents of the Locations table.You can insert new records and modify existing data directly in this view window.

In our case, we will use a simple "natural join", because both tables have the same "location_id" column that holds values of the same data type. This join selects only the rows that have equal values in the matching location_id column.

This SQL query returns the rows from the Departments table whose location_id values are equal to the values in the matching column in the Locations table, with the results being ordered by the Department name. Note that you cannot insert new records directly in the results of this query, as you could do in the representation of a single table.

You can save the SQL join query as a View (right-click the View node and choose Create View) and run it conveniently whenever you want. For this, the database user should be granted the privilege to Create View that our sample user does not have. You can log in under the system account, grant jim the Create View privilege (with this SQL statement: "grant create view to jim;") and try creating your own view.

If you were following this tutorial, you already used the capabilities of the NetBeans IDE SQL Editor. Here we list several other capabilities of the NetBeans IDE SQL Editor that might be useful to you.

GUI View of Database Tables. When you right-click a table node in the Services window and choose View Data, the IDE displays a visual representation of the table and its data (as shown in the figure above). You can also add, modify, and delete table data directly in this view.

To add a record, click the Insert Records icon and insert new data in the Insert Records window that opens. Click the Show SQL button to see the SQL code for this operation. The table will be automatically updated with the new records.

To modify a record, double-click directly inside any cell in the GUI View of a table and type the new value. Until the change is committed, the modified text is shown in green. To commit your changes, click the Commit Changes icon. To cancel changes, click the Cancel Edits icon.

Keep Prior Tabs. Click the Keep Prior Tabs icon on the SQL Editor toolbar to keep the windows with the results of previous queries open. This can be helpful if you want to compare the results of several queries.

SQL History (Ctrl-Alt-Shift-H). Use the SQL History icon on the SQL Editor toolbar to view all SQL statements that you ran for each of the database connections. Choose the connection from the drop-down list, find the SQL statement that you need and click Insert to place the statement to the SQL Command window.
