Oracle 11g Grid : Using EMCLI to run Remote OS Commands

Here , I wish to locate disk space acquired by a Remote target Host using df command

Please read post Using EMCLI , A command line Grid Control Interface to understand how EMCLI is used

C:\EMCLI>emcli execute_hostcmd -cmd=”df -k”  -targets=”sagar-pc:host”
Error : Preferred Credentials do not exist for some targets.

The error indicates preferred user credentials are not set at Grid cntrol for this host.

Navigate to Grid -> Preferences -> Preferred Credentials -> Host ( I selected host as my target to run above command and not database)

One can set Default Credentials applied to all hosts or specific details for each individual Host

Test entered credentials by using “test button” and run  failed command again.

C:\EMCLI>emcli execute_hostcmd -cmd=”df -k”  -targets=”sagar-pc:host”
