How to initiate emcli session on OMS host

 EMCLI Basic commands

EMCLI stands for Enterprise Manager Command Line Interface. This binary is located under $OMS_HOME/bin or $ORACLE_HOME/bin - whichever is set for the oms installation. Sometimes it can be MIDDLEWARE_HOME. It is actually depends on how the admin configured the environment. For a better understanding check where the oms middleware is installed.

you can check this by running which emcli, it will show if the ORACLE_HOME/bin is part of the PATH variable and it can be executed without changing directory to ORACLE_HOME/bin. 

else,

cd $ORACLE_HOME/bin and run the below command.
