As with many communication products, BRMS uses the default local location name (LCLLOCNAME) rather than the system name (SYSNAME). In most cases, the System i platforms have the same value specified in LCLLOCNAME as in SYSNAME. BRMS also uses the local network identifier LCLNETID. You can change these values at the Change Network Attribute (CHGNETA) display. You can review the values at the Display Network Attribute (DSPNETA) display. Other network attributes do not affect BRMS.
When you install BRMS Networking, many of the BRMS commands like WRKMEDBRM, WRKMEDIBRM, and STRRCYBRM support a FROMSYS parameter, allowing you to perform the operation using the data retrieved from the networked system using Distributed Data Management (DDM). If your BRMS network is configured to use TCP/IP, BRMS attempts to create the DDM file using TCP/IP and if that fails, will attempt again using APPC. If a connection to networked system cannot be made, BRMS will use data available on the local system.
The APPC connection method allows a system in restricted state to communicate with other systems in the network which are not in restricted state. This capability is possible using TCP/IP but must be configured to do so. If you need this capability and want to use TCP/IP as your primary communication method see Configuring TCP/IP for Restricted State. You should also consider configuring APPC as well as TCP/IP if you want BRMS to use APPC as an alternate communication method when TCP/IP communications is not available.
