SAP on windows listening on "0.0.0.0"

[former_member189252]

I am checking SAP Java application that is started on one of our app server. I notice that all the "listening" ports show IP as "0.0.0.0". e.g., as shown below. None of them are listening on actual ip of the windows server. What OS issue could this issue be?

Hi Giridhara,

In this case the 0.0.0.0 means all the IPv4 addresses on the machine. For example with IP addresses 192.168.1.1 and 10.10.10.1 the listening ports will be available on both IP addresses.

Best regards,

Antal

Hello Giridhara Tadikonda,

Can you please check what are the access point for your SAP systems in SAPMMC?

There must be proper IP address listed with IP and port
