I ran the script /usr/sap/DAA/SMDA98/script/smdsetup.sh in my managed system to change it to a different managing system, since I had originally registered it to our DEV SolMan and we decided to move it to our PRD SolMan.
The original setting in runtime.properties was:
smd.agent.connection.url=ms\://sapsmd\:8166/P4
After I ran the script with this command line:
smdsetup managingconf hostname:"sapsmp" port:"8161" user:"SOLMAN_ADMIN" pwd:"xxxxxxx"
The setting in runtime.properties changed to:
smd.agent.connection.url=p4\://sapsmp\:8161
After restarting the system, it would not show up in the SLD on in the PRD SolMan system
I manually edited the runtime.properties file and changed the setting to:
smd.agent.connection.url=ms\://sapsmp\:8161/P4
to make it look like the the original setting, and the agent showed up in SolMan PRD
Just my .02
