SAP Message Server ACL configuration file for JAVA

244 Views Last edit Dec 12, 2022 at 11:16 AM 2 rev

Hi Team,


We have a requirement to configure restrictive message server ACL file .
As the central communication component in a SAP system network, the Message Server should be protected against unwanted external access. With an ACL (Access Control List) we can control which hosts are permitted to open a connection to the Message Server. A separate ACL can be used for each port on the Message Server.
ACL file must include all host names, domains, IP addresses and/or subnetwork masks from which application servers are allowed to log on to the Message Server.

In order to maintain entries in ACL file, we have to analyze the interfaces currently in use, in order to avoid disrupting existing and required connections.

we got to know that when we enable gw/sim_mode parameter in ABAP, we will get connected systems list.

Is this parameter applicable for Java?
Is there any other parameter or any other way to get connected systems list for Java?

Can you please provide information on how to collect interfaces system list for Java system.
