 Would you be interested in knowing what causes ORA-12154 error and how to resolve it? Are you also interested in knowing important tips in order to resolve ORA-12154 error? If so, then you reached the right place. In this article, we will understand how to fix this error. Let's start.

What is ORA-12154 error in Oracle database?

ORA-12154: TNS could not resolve service name is a common error encountered while connecting to an Oracle database. This error occurs when the TNS (Transparent Network Substrate) service is unable to find the service name specified in the connection string.

Here are some tips to resolve the ORA-12154 error:

• Check the TNSNAMES.ORA file: This file is used by TNS to resolve the service name to an actual database connection. Check the file for any spelling or syntax errors in the service name.

• Verify the service name: Make sure that the service name specified in the connection string matches the service name defined in the TNSNAMES.ORA file.

• Update the TNS_ADMIN environment variable: If you are using a different TNSNAMES.ORA file, make sure that the TNS_ADMIN environment variable points to the correct location.

• Check the listener status: Ensure that the listener is running and able to accept incoming connections. You can check the listener status by using the “lsnrctl status” command.

• Restart the listener: If the listener is not running, restart it using the “lsnrctl start” command.

• Check the network connectivity: Verify that the server hosting the database is reachable and there are no network issues preventing the connection.

• Reinstall the Oracle client: If all other steps fail, reinstalling the Oracle client may resolve the ORA-12154 error.

• Verify the Oracle Home environment variable: Make sure that the Oracle Home environment variable is set correctly to the location of the Oracle client software.

• Check the SQLNET.ORA file: This file is used to configure the Oracle Net Services that provide the communication between the client and the server. Verify that the correct settings are configured in the SQLNET.ORA file.

• Use the TNS Ping utility: The TNS Ping utility is used to test the connectivity to the database by checking the availability of the listener. You can use the “tnsping” command to run this utility.

• Check the firewall settings: If the server hosting the database is located behind a firewall, verify that the firewall is configured to allow incoming connections on the specified port.

• Disable the Windows Firewall: If the Windows firewall is enabled, it may be blocking the connection to the database. Try disabling the Windows firewall temporarily to see if it resolves the ORA-12154 error.

• Check the port number: Make sure that the port number specified in the connection string matches the port number used by the listener.

• Try a different connection method: If the error persists, try connecting to the database using a different method such as SQL*Plus or SQL Developer.

• Check for multiple TNSNAMES.ORA files: If you have multiple Oracle client installations on the same machine, there may be multiple TNSNAMES.ORA files. Make sure you are using the correct TNSNAMES.ORA file for your current Oracle client installation.

• Check the service name format: The service name can be specified in different formats such as a simple string, an easy connect string, or a connect descriptor. Make sure that you are using the correct format for your particular scenario.

• Upgrade the Oracle client software: If you are using an outdated version of the Oracle client software, upgrading to the latest version may resolve the ORA-12154 error.

• Check for incorrect hostname or IP address: Verify that the hostname or IP address specified in the connection string is correct and matches the actual hostname or IP address of the database server.

• Verify the SERVICE_NAME parameter in the database: If you are connecting to a database that uses the SERVICE_NAME parameter instead of the SID, make sure that the service name specified in the connection string matches the actual service name in the database.

• Check the network configuration: If you are using a complex network configuration such as a VPN, make sure that the network is configured correctly and that the database server is accessible from the client machine.

• Verify that LDAP is listed as one of the values of the names.directory_path parameter in the sqlnet.ora Oracle Net profile.

Verify that the LDAP directory server is up and that it is accessible.

 

Verify that the net service name or database name used as the connect identifier is configured in the directory.

 

Verify that the default context being used is correct by specifying a fully qualified net service name or a full LDAP DN as the connect identifier

By following these tips, you should be able to resolve the ORA-12154 error and successfully connect to your Oracle database. If the error persists, it is important to seek the help of a qualified Oracle database administrator or support specialist.

What is Null Pointer Error in Java and How to fix it?

Are you looking for what is best way to fix Null Pointer error in your Java code? Are also would like to know what causes Null Pointer error. If so, then you reached at right place. In this article, we will understand what is root cause of Null Pointer error and how to fix it. Let's start.

 A null pointer error, also known as a "null reference exception," occurs when a program attempts to access an object or variable that has a null value. In other words, the program is trying to access an object that doesn't exist. This can happen when a variable is not initialized or is set to null, but the program tries to access it as if it has a value.

The error message will typically indicate the specific location in the code where the error occurred, and it will look something like this: "java.lang.NullPointerException at [classname].[methodname]([filename]:[line number])".

There are several ways to fix a null pointer error, but the most common solution is to check for null values before trying to access an object. This can be done by using an if statement to check if the variable is null, and if so, assign a value to it or handle the error in a specific way.

Another way is to use the "Optional" class introduced in Java 8, it allows to avoid null pointer exceptions. It can be used with any type of variable and it wraps the variable and it can check if it's present or not.

For example, if the error occurs when trying to access an object called "objectName," the following code can be used to fix it:

if (objectName != null) {

    // code to access objectName

} else {

    // handle the error or assign a value to objectName

}

Additionally, you should check that the objects that you're using are not null, it's also important to check that the objects that the object you're using is not null. To avoid this error, it's important to initialize variables and objects properly and to be aware of the scope of the variables and objects that you're using in your code.

In summary, a null pointer error occurs when a program tries to access an object or variable that has a null value. The error can be fixed by checking for null values before trying to access an object and handling the error properly. It is important to initialize the variables and objects properly, check for the scope of the variables and objects, and to be aware of the potential of null values.

What is data governance?

 Data governance is the set of processes,  programs, and norms that associations use to insure the quality, vacuity, and security of their data. It involves a range of conditioning, including data operation, data quality assurance, data security, and compliance.  

One of the main pretensions of data governance is to insure that data is accurate,  harmonious, and dependable. This is fulfilled through data operation practices similar to data confirmation, data sanctification, and data standardization. Data quality assurance is also an important aspect of data governance, as it helps to identify and correct crimes or inconsistencies in the data.   Another important aspect of data governance is data security. Organizations must insure that their data is defended from unauthorized access, as well as from accidental or purposeful breaches. This can include enforcing security controls similar to firewalls, intrusion discovery systems, and encryption.   Compliance is also a major concern for associations, as they must cleave to a variety of laws and regulations that govern the use and running of data.

 This can include regulations similar to the General Data Protection Regulation( GDPR) in the European Union and the Health Insurance Portability and Responsibility Act( HIPAA) in the United States. Organizations must insure that their data governance practices align with these regulations to avoid expensive forfeitures and penalties.   Data governance is a critical aspect of any association's operations, as it helps to insure the quality, vacuity, and security of their data. It involves a range of conditioning, including data operation, data quality assurance, data security, and compliance.

By enforcing effective data governance practices, associations can ameliorate their decision-making capabilities,  cover their character, and achieve compliance with laws and regulations.    enforcing data governance can be a complex process, as it involves numerous different stakeholders and can have a significant impact on an association's operations. thus, it's important to have a clear and well-defined data governance framework in place.

 

This frame should include the places and liabilities of the colorful stakeholders, as well as the programs and procedures that will be used to govern the data.   One of the crucial factors of data governance is a data governance council. This council is responsible for creating and administering the data governance programs and procedures. It should be made up of representatives from colorful departments within the association,  similar to IT, legal, and compliance. This will insure that all stakeholders have a voice in the data governance process and that the programs and procedures are aligned with the overall pretensions of the association. 

 

 Another important aspect of data governance is data governance software. This software can automate numerous data governance processes,  similar to data confirmation, data sanctification, and data standardization. It can also help to cover the data to insure compliance with laws and regulations. also, it can give real-time visibility into the data, which can help associations to identify issues and take corrective action more snappily.   Data Governance isn't a one-time event, it requires ongoing monitoring and conservation to insure that the data is accurate,  harmonious, and secure. Regular checkups should be conducted to insure that the data governance programs and procedures are being followed and to identify any areas for enhancement.  

 

In conclusion, data governance is a critical aspect of any association's operations. It helps to insure the quality, vacuity, and security of the data, which is essential for effective decision-  timber,  guarding character, and achieving compliance. Organizations should apply a clear and well-defined data governance frame, including a data governance council and data governance software to automate processes. Regular monitoring and conservation are also crucial to icing the ongoing effectiveness of data governance practices.

How to connect to Database in Java?

 To connect to a database using Java, you will need to use the JDBC (Java Database Connectivity) API. This API provides a standard set of interfaces for connecting to a database, executing queries, and processing the results.

 

Here is an example of Java code that demonstrates how to connect to a database using JDBC:

 

import java.sql.Connection;

import java.sql.DriverManager;

import java.sql.SQLException;

 

public class DatabaseConnection {

 

    public static void main(String[] args) {

 

        // Load the JDBC driver

        try {

            Class.forName("com.mysql.jdbc.Driver");

        } catch (ClassNotFoundException e) {

            e.printStackTrace();

            return;

        }

 

        // Establish a connection to the database

        Connection connection = null;

        try {

            connection = DriverManager.getConnection(

                "jdbc:mysql://localhost:3306/mydatabase", "username", "password");

        } catch (SQLException e) {

            e.printStackTrace();

            return;

        }

 

        // Do something with the connection, such as executing a query

        // (omitted for brevity)

 

        // Close the connection

        try {

            connection.close();

        } catch (SQLException e) {

            e.printStackTrace();

        }

    }

}

 

 

In this example, we first load the JDBC driver for MySQL using the Class.forName() method. Then, we use the DriverManager.getConnection() method to establish a connection to the database. Finally, we close the connection using the Connection.close() method.

 

Note that this example uses MySQL as the database, but you can use a different database by simply changing the JDBC driver class and the connection URL. You will also need to provide the appropriate username and password for the database.
