Upgrading Network Configuration Manager to the most recent version will help you stay more secure with security fixes, enhance performance with bug fixes, and gain out-of-the-box functionalities with new feature releases. This helps you maintain optimum network performance, while ensuring network security.

  • If product is stopped but postgres processes are not killed properly then run stopPgSql.bat/sh to make sure all postgres processes are stopped:

    • Open the command prompt or terminal
    • Move to the bin directory on entering the command <NCM-Home>/bin
    • Execute stopPgSql.bat/sh file to stop the processes.
