Installation of NGL3

1. Download NGL3 from this link. If you have already downloaded this file in the Download page, skip this step.
2. This will download a file Extract this file, for this example we have extracted the zip file into D: Drive. In D: Drive you will now see a directory name "InstallNGL3.0". The contents of this directory.

3. Place you database backup file in InstallNGL3.0/DBBackup directory. This database backup must be in "Plain format with insert commands"
4. Now go into D:/InstallNGL3.0/apache-ant-1.8.1/bin directory. In this directory you will find a file config.ini. open this file using Wordpad or Notepad. Edit the parameters as explained below.
This means that the NGL installation will be made in the directory C:/NGL3. you may give choose any other directory as you wish. But for this example we will choose this directory.

The IPAddress of the computer which is running Postgresql database. By default leave it as localhost. It means that Postgresql database server is running on this system itself.

The Port on which your Postgresql Server is running. In most of the cases this port number is 5432.


Do not edit this parameter. Postgresql 8.3 installation creates a default database called postgres


Default database user is postgres. So do not edit this value.


The password you entered for postgres. In our installation manual we asked to give the password as newgenlib.

This is the location which has NGL3.0 Installation files. Refer to Point 2.
If you are using windows leave this parameter as it is.

If you want to restore a blank NGL schema the above value is blank. If you want to restore a NGL backup(with data) instead of a blank schema then put the backup file in D:/InstallNGL3.0/DBBackup directory. Instead of blank use original. Your parameter will look like this restore.database=original

Do not edit this parameter. If you want the database name to be something else you may change it here.

Do not edit this parameter. A new user with this name will be created


Do not edit this parameter. The user will be created with this password.

Save the changes made to config.ini

5. Go to D:/InstallNGL3.0 and Double click on Install batch file. This will Open command prompt and execute the scripts as shown below

6. Go to C:/NGL3 apache-tomcat-6.0.32/bin directory. You can see a file RunNGL3Server batch file.

This batch file when executed will run the apache-tomcat Server with NGL Application. Since you have use this batch file frequently let us create a shortcut of this file on the desktop. Right click on RunNGL3Server and Send to ---> Desktop (Create Shortcut) as shown below.

A shortcut will be created on your desktop as shown below.

7. Double click on the Shortcut to start NGL Server. The NGL Server (apache-tomcat) will start. It will take some time to initialize. Finally you will get a message as shown below. The time taken for server to initialize will change system to system.

Check if the installation is working

1. Make sure that your NGLServer is running. (Point 6 of above section).
2. Click on this link. http://localhost:8080/newgenlibctxt. This should open Web OPAC as shown below.

3. Now the Installation is running, we will now have to create a Solr Index of Bibliographic and Authority data. Please note that unless you execute this step you will not be able to make searches.
Go D:/InstallNGL3.0 directory you will find a file BuildIndex batch file. Double click on this file. This will create Bibliographic and Authority data Index.
