Run checks prior to installation using the nnl-install.sh script. It verifies that you’ve installed the right OS version, JDK version, and database version. It also checks database connectivity.

Using administrator privileges, run the script:

cd <NNL_HOME>/install/
./nnl-install.sh -pre-install-check

The script generates a text report. Review the report and fix any issues that were flagged.
