XCON: Interoperability Logs (AP0.LOG) (163321)
The information in this article applies to:
- Microsoft Exchange Server 5.5
- Microsoft Exchange Server 4.0
- Microsoft Exchange Server 5.0
This article was previously published under Q163321 SUMMARY
Interoperability text logs consist of the binary content of X.400 protocol
messages passed between Microsoft Exchange Message Transfer Agents (MTAs)
on different Microsoft Exchange Servers and between MTAs and client
applications. They are used to log messages sent over internal interfaces
(XAPI, ACSI, TSI, and NSI).
MORE INFORMATION
Increasing Diagnostic Logging levels to Medium or higher for both the
Interoperability and Interface categories will generate AP*.LOG files in
the exchsrvr\MTADATA directory. The current log is always named AP0.LOG.
Prior logs are named AP#.LOG with the # increasing with the age of the log.
When a log reaches 5 megabytes in size it is renamed and a new log is
begun.
NOTE: There is no difference between Medium and Maximum for the
Interoperability category. However, in addition to its influence on
Interoperability logs, the diagnostics logging level of the Interface
category determines which Interface events are written to event logs.
Interoperability logs can be instrumental in tracking down configuration
problems on MTAs. However, they are valuable only to those familiar with
ASCII translations of X.400 protocol. These logs can grow quite large very
quickly and cause performance on the Server to suffer.
