The SIDs are extracted from the process list via "ps -ef".
Some of the extracted SIDs may have a pre- or postfix in
(ADDRESS = (PROTOCOL = TCP)(Host = HOSTNAME)(Port = PORT))
(CONNECT_DATA = (SID = SID)(GLOBAL_NAME = SID.POSTFIX))
The pre- or postfix can be configured in mk_oracle.cfg, eg.
PREFIX='GLOBAL_PRE_' # for all SIDs
PREFIX_SID='SPECIFIC_PRE_' # for the specific SID 'SID'
The same works for 'POSTFIX'.
