Alarm THE REX CONNECTOR PROCESS DIED was raised a week before.
the rex connector process was down.
Release : 21.2.x
Component : Spectrum Integrations
Because IP Routing Manager is not used
As you are not using the IP Routing Manager move the REXCON.IDB file from %SPECROOT%/lib/SDPM/partslist folder to any other folder.
Recycle the spectroserver and process daemon services
cd SS/bin
./stopSS.pl
cd lib/SDPM
./processd restart
cd SS/bin
./startSS.pl
Now the RexConnector will not start.
