The Easiest Way to Connect with Clients After Database Migration

The process of migration of database, from the old Oracle server to a new one, is a difficult task on its own. And the process of reconfiguration with all the different clients and branches make it more difficult for the business owners.

Once the process of migration has been done, most of the time of the IT employees of the company gets consumed in the connection process. They re-connect all of their workstations again with the new server. In most cases, the lack of ample time period enhances the risk of errors.

Some simple mistakes can create bad connection issues on the new server. The process requires proper focus and skill in order to successfully implement the configuration process after the migration.

Some prefer to use a single tnsnames.ora file for all the workstations. This works well until there is a minor network issue. These minor network issues can become very problematic for the users. This method is only practical when the user is upgrading client software on the different workstations.

However, there is another way to reduce this time lag between the database migration in oracle and the re-configuration. You can add service and the name of all the different clients and branches as an additional entry on the new server. This will reduce a lot of editing time for you after the migration.

The Method parallel server

This method doesn’t just allow the administrator to create a new database server parallel to the existing network, but also let the user test and get comfortable with the new environment of the server. Plus, the connection with the client doesn’t get lost during the whole process.

There are some key steps that you need to follow during shifting of the production to the new server.

  1. After the process of the migration has been done and you are ready to shift from the old server to the new one, make sure that you close the original database server. If you don’t take the old server offline, it will conflict with the new one on your network. This can become problematic for you, so keep this point in mind.
  1. Once the old server is offline, you can change the name of the host of the new database server. Make sure that the hostname matches the name of the host of the original server. This step is to break the database bond between the old and the new database server.
  1. Now you need to re-configure the Domain Name System (DNS). This will blend the original host name to the new server. On the contrary, you can change the IP of the new server in order to match the old server.
  1. Finally, add all the services and the names of the different clients from the old server to the new database server.

Now, all of your clients can connect to the new server of the database.

Hence, this is the most efficient way to re-connect with the clients after the migration process.
