Hello Uday,
what do you mean with "CI"? An ABAP instance with the enqueue service or an ASCS instance? If an ABAP instance is running on the DB server, then you do not need a sapccmsr agent. If with CI do you mean the ASCS instance, then a sapccmsr is required. You should be aware, that in SAPHOSTAGENT an integrated sapccmsr is running and if you want to use a standalone sapccmsr you should deactivate this integrated one first.
