Try the command line option.

opr-node Command-Line Interface - Operations Bridge Manager (microfocus.com)

Hi, I tried below command

opr-node -username admin -password mypassword -add_node -node_name roopesh001.test.com ci_name roopesh001 -os_type "Windows Server 2012 (6.2)" -processor_family x86_64 -ci_type nt -node_group mygroup

But getting error as "
ERROR: The following arguments are not recognized by this application:
ci_name, mynode
INFO: Enter -help or -h to find help using the tool
ERROR: Operation failed"

Any suggestion whats wrong in command?

ci_name is missing hyphen, also you don't need to provide ci_name it will take it from your -node_name automatically.

ran as below;

opr-node -username admin -password mypassword -add_node -node_name roopesh001.test.com -os_type "Windows Server 2012 (6.2)" -processor_family x86_64 -ci_type nt -node_group mygroup

Now getting error as "WARN: Default virtual gateway server URL isn't a valid URL.: java.net.MalformedURLException -- java.lang.NullPointerException
java.lang.IllegalArgumentException: Illegal character in authority at index 7: http://<unspecified>:80/opr-config-server/rest/systemArchitecture/osList"

check the online docu: https://docs.microfocus.com/doc/Operations_Bridge_Manager/24.2/Clioprnode

You probably need to use -server or -url.

command runs properly on my 2022.05 and 24.2 instances.

thanks, in that case there is something wrong in my DPS computer which is not allowing this process to work? I use Windows 2016 server to run DPS.
