System Default Port Numbers

                  System Default Port Numbers

Ports with numbers 0–1023 are called system or well-known ports; ports with numbers 1024-49151 are called user or registered ports, and ports with numbers 49152-65535 are called dynamic, private or ephemeral ports.
One of the challenging tasks for an administrator is to remember the default port number.
You may remember the most common ones like HTTP, FTP, SSH but if you are working on various technology stacks then it’s difficult to remember all of them.

Here I have listed the default port numbers of various applications to help you in the real world.

IBM WebSphere - Synchronize a node (syncNode)

Image
  IBM WebSphere - Synchronize a node (syncNode) Before we get into synchronization, let's talk about nodes and the master configuration. The master configuration is a collection of XML files that contain all sorts of information about a cell, such as the security settings and the applications in the cell. A node contains one or more WebSphere application servers. When a managed nodes is federated into the dmgr, the node needs to be synchronized with the master configuration so that the node is using the dmgr configuration. The synchronization is always from Dmgr to Nodes and it never happens vise versa. If you made any changes from the node side it will be cleared during next synchronization process. Let's consider a common example. You make some change in the WebSphere admin console, and you are presented wit the Save option. Selecting save updates the master configuration. This will cause the node to be out of sync with the master configuration. To know if a node is synchroni...

Backup and Restore of WebSphere Application Server configuration

                      Backup & Restore of IBM WebSphere Application Server Configuration Backup configuration in  WebSphere One of the major activity that we can perform in Websphere as a pre-requisites when ever we intended to perform any major configuration changes like Fix Pack upgrade ,Interim Fix upgrade, JDK upgrade etc. For any mission critical application, taking frequent backups is essential for recovering from severe errors. In the case of WebSphere Application Server, setting up of the application server environment is a demanding task and it is not an easy to repeat the setup if something bad happens. So, its wise to take backups whenever we make the first setup or when we do configuration changes. Depending upon our diskspace availability two types of backups is possible . 1) Full Backup A full backup can be performed by running the ./backupConfig command from the<WAS-ROOT>/bin di...
