When installing the Network Node Manager iSPI for MPLS when configuring for Oracle database. There is now way to change the default database port from 1521 to XXXX.
There is no option provided during installation to configure a different port for the Oracle DB instance for MPLS. It always uses the 1521 by default. And because of this the installation fails as the connection to the DB instance with port 1521 always failed.
To resolve this issue, modify the installation port using the below steps:
1) Start the MPLS SPI installation.
2)After entering the MPLS oracle server name and the instance name information, you will be taken to a page where you will be asked to enter the database user name and password.
3) Before entering anything in the above page, open the file /tmp/ovinstallparams.ini. Here, you modify the "db.port=1521" to "db.port=XXXX'
Save the changes.
4) Then go back to the installation window and continue with installation by entering the db user name and password details.
