Hi Alwina,
I had already set the parameter ccms/enable_agent=0. There are 2 log files under /usr/sap/hostctrl/work/sapccmsr, one old and one which is current. I've attached a text file with contents of both logs.
Also, can you please confirm where should the ccms agent be installed - on the DB server or the CI server?
regards,
Suraj
