Solution Manager Agent on the fly

[Former Member]

Hello,

I have installed diagnostic agents on a MSCS cluster. When I enable Agent on the fly within Solution Manager the agent restarts every 2 minutes. In the log file I get the message :

Error      [AgentNodeControllerHelper] Cannot add agent node grndbxxxx.

[EXCEPTION]

com.sap.smd.nodes.controller.NodesMaintenanceException: Command executed: D:\usr\sap\DAA\SMDA97\script\smdsetup.bat installer addagent virtualhost:grndbxxxx servername:grndbxxxx keep:connection sid:DAA inr:97  / command returned: Access is denied.

When I run the command in a dos box it works, but with a failover he wants to uninstall and I get the same error.

I have given the group everyone full control on the folder SMDA97 but it didn't work.

When I disable agent on the fly every thing works just fine.

Who can help me ?

Thank you,

Stefan

Hi,

This is probably a permission issue at OS level. When you enable the agents on the fly, the application needs to exdecute the script to create the agent node. This script needs to create files and folders within the SMDAgent folder. Ensure that the SMDAgent OS user has enoguh permission to execute this actions.

Also, you may change the file SMDAgentApplication to debug mode, this will provide you more details about the error. You should find the root cause in debug mode.

Hello Allam,

Permissions were the problem, the sapservicedaa user must have enough permissions to run the script. Local admin did the trick.

Thanks,

Stefan

Hi,

servername:grndbxxxx keep:connection sid:DAA inr:97  / command returned: Access is denied.

what is your diagnostic agent version? sometime you get triggered these errors due to version mismatch? Refer the sap  SAP Note 1365123 for the Diagnostics Agent installation strategy and version details.

Thanks

Hello,

Yes As the jansi says it a related to version mismatch follow the note

Hello Jansi,

I have installed the diagnostic agent again using note 1365123. The problem still exist. When I disable the agent on the fly feature al works well. My version is 7.30. I will post the log with the error.

The problem is when the smdagent tries to create an agent for the logical hostname of the node.
