Verify That Your Server is Ready for Installation 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: ```plaintext cd /install/ ./nnl-install.sh -pre-install-check ``` The script generates a text report. Review the report and fix any issues that were flagged.
