1.2.3 Check the port to use
Before you install JP1/AO on Linux 8, verify that the ports that JP1/AO will use on the JP1/AO server are not in use by other products. If a port is being used by another product, neither product might operate correctly.
To ensure that the necessary ports are not in use, use the netstat or ss command.
You must verify that port numbers 22170 - 22173 are not used by other products because this causes a new, overwrite, or upgrade installation to fail.
