Can we have uCMDB with both HP SM and BMC Remedy integration concurrently?
Does uCMDB provide web services functionality?
I am not sure what you mean "concurrely", both integrations can be HP SM and BMC Remedy can coexist on the same server.
Ucmdb does provide web services functionality. i.e. http://<ucmdb_name>:8080/axis2/services/listServices
you can log with the default sysadmin/sysadmin
