Troubleshooting Your OSI/MHS Subsystem

Effects on the System
•
OSI/AS (TAPS) traces, with minimum of L5, L6, ACSE trace records, and record
size of 4042 (maximum value)
•
SCF configuration files for OSI/AS and OSI/MHS
•
EMS event log (with accounting events turned on)
Effects on the System
Interconnection problems cause minimal impact on the subsystem, with the exception
of the connection to the adjacent MTA. OSI/MHS cannot relay a message to an MTA
with which it has no connection; it cannot receive messages from an MTA whose
connection it has refused.
