Orachk does not recognize DB instance when SID is prefix of another SID
Depending on the start order of the instances resp. the process ID of the corresponding PMON process, OraChk may or may not discover an instance if the SID is a prefix of another SID.
(The system is not running Oracle Grid Infrastructure resp. Oracle Restart).
