Does oracle database require jdk?
Oracle database requires jdk. The reasons are: 1. When using specific software or functions, other software or libraries included in the JDK are required; 2. Java JDK needs to be installed to run Java programs in the Oracle database. ; 3. JDK provides the function of developing and compiling Java applications; 4. Meets Oracle's requirements for Java functions to help implement and implement specific functions.
#The operating environment of this article: Windows 10 system, Oracle version 19c, dell g3 computer.
Oracle Database is one of the most popular database management systems in the world, and its reliability and efficiency make it a key strategic tool. People often ask whether JDK (Java Development Kit) is needed to install Oracle database? The answer is yes—but in some cases, there are a lot of questions.
In short, to correctly install and use Oracle database, you need to install Java JDK, other software or libraries included in JDK are only required when you use specific software or features. In addition, Oracle Enterprise Edition may require the installation of Java JDK or Java Runtime Environment (JRE), depending on the functionality you want to implement.
JDK is commonly used with IDEs such as Eclipse, NetBeans, and Sun JavaStudio. They provide functionality for developing and compiling Java applications, as well as improving the performance of Java applications. However, there is another important use of using JDK, which is to allow you to run Java programs in an Oracle database.
For example, you may need to call and execute complex server-side Java stored procedures, which requires the Java Definer client JDK. Starting from Oracle version 10g, JVM (Java Virtual Machine) has been built into the database, and you can use the internal JVM version to execute Java programs without installing an external Java client (such as JDK).
In addition, Oracle 10g and all new versions support custom Java functions, which allows application developers to write custom Java functions in the Oracle database to help implement and implement specific functionality. However, to meet Oracle's requirements for Java functions, you must install the correct, latest version of the Java JDK.
Of course, you can still write and execute stored procedures, functions and triggers in the database without using Java, so there is no need to install the Java JDK. Generally speaking, if you just want to use Oracle to manage data, you do not need to install JDK, but to use some more complex functions, you may need to install Java JDK.

How to solve the problem of closing oracle cursor
Apr 11, 2025 pm 10:18 PM
The method to solve the Oracle cursor closure problem includes: explicitly closing the cursor using the CLOSE statement. Declare the cursor in the FOR UPDATE clause so that it automatically closes after the scope is ended. Declare the cursor in the USING clause so that it automatically closes when the associated PL/SQL variable is closed. Use exception handling to ensure that the cursor is closed in any exception situation. Use the connection pool to automatically close the cursor. Disable automatic submission and delay cursor closing.
