Cause: The agent control utility was unable to access its parameter file. This could be because it could not find its admin directory or because permissions on directory were not correctly set. See the solution below.

Error solution: The agent control utility puts its parameter file in either the directory pointed to by the environment variable AGTCTL_ADMIN or in the directory pointed to by the environment variable TNS_ADMIN. Make sure that at least one of these environment variables is set and that it points to a directory that the agent has access to.
