Not Able to Start OracleXNTNSListener in Windows Environment

To resolve this issue,

Goto your oraclexe directory and navigate to network/ADMIN 

   e.g oraclexe\app\oracle\product\11.2.0\server\network\ADMIN

Open (listener.ora) in notepad and replace the HOST address with your localhost or current-ip

e.g

 LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
      (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
    )
  )

 DEFAULT_SERVICE_LISTENER = (XE)

Open (tnsnames.ora) with notepad and replace HOST address with your localhost or current-ip address.

e.g

 XE =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = XE)
    )
  )

Open your command prompt as adminstrator and run lsnrctl start


NB: You might have to map localhost to 127.0.0.1 in the C:\Windows\System32\drivers\etc\host file by adding 127.0.0.1       localhost

This phenomenon can be frustrating, especially when it indicates that the connections are not being closed properly by the server or client. In our investigation, we found that the culprit behind this issue was an HTTP error code 513 being sent to clients from servers. This error code indicates that the server is overloaded and cannot handle more requests. Furthermore, the client was logging a socket close event, which meant it was terminating the connection prematurely. To replicate this issue, we used JMeter and found that the max concurrent connection limit was reached, resulting in an HTTP error code 513. The allowed queue was also full, contributing to the problem. So, what are the consequences of this issue? Performance degradation and resource wastage on both servers and clients ca...

Java Client SSL Setup and Related Errors

Troubleshooting Tips for Effective Configuration Configuring Secure Sockets Layer (SSL) is a crucial step in ensuring the security of your Java client's communication. In this article, we'll walk you through the process of configuring SSL and provide guidance on troubleshooting common errors that may arise during the setup. To troubleshoot issues effectively, follow these steps: - Enable the JVM option -Djavax.net.debug=all - Capture the network traffic dump for faster analysis. Certificate Setup Go to your console and access your <JAVA_HOME>/bin/keytool NB :  The default location for saving the generated files is the user home directory. You can change this by specifying a path. STEP 1: Generate a new key (private key) for a Keystore. This either creates a file called <KEYSTORE_NAME>.keystore or update an existing file if it already exists. The CSR which will be presented to a Certificate Authority (CA) will be generated with this key and alias. <J...
