Introducing the Administrative Utility
The OSI/MHS Administrative Utility (AU) product supports AU-specific requests and
responses between an AU server and a World Wide Web browser, which provides the
user interface (see Appendix A, Recommended Settings for Your Browser, for
information about setting up your browser for best viewing of the AU screens). The AU
allows you to obtain information about messages, reports, and probes (communications
sent by an originator to the message transfer system (MTS) to test delivery of a message
or report) in the form of Protocol Data Units (PDUs) within an OSI/MHS subsystem
from a workstation platform using a Web browser.
The AU’s features allow you to do the following tasks:
•
List PDUs based on selections made from either the control screen or the
subsystem-filter screen. Each screen is described in detail in Section 3, Using the
Administrative Utility.
•
Suspend or remove a PDU, or activate a suspended PDU from the route-retry or
link-retry queue. You also can remove PDUs from the gateway queue.
•
Delete bad-state PDUs from the subsystem.
•
View statistical information for all configured groups in the OSI/MHS subsystem.
•
Display PDUs in one of the following formats:
•
Decoded message, which is the PDU in decoded format.
•
Decode trace, which is a detailed trace of the ASN.1 decoder.
•
Encoded message, which is the PDU in encoded (hexadecimal) format.
•
Logs, which are log records for this PDU.
Overview of the AU Design
As shown in Figure 1-1, the AU is implemented as two Pathway server classes: the
AU-DISTRIBUTOR class and the AU-SERVER class.
The AU-DISTRIBUTOR class monitors the TCP/IP port defined in the Pathway
configuration (See Section Figure 1-1, Components of the AU and Their Relationships
,
for information about Pathway configuration considerations for the AU). The
AU-DISTRIBUTOR class listens for a connection on a TCP/IP port and performs a
Pathsend procedure call to start an AU-SRVR process. The AU-SRVR process then
responds directly to Web browsers using TCP/IP.
The HyperText Transfer Protocol/HyperText Markup Language (HTTP/HTML)
requests accepted by the AU-SERVER class are specific, AU-formatted request strings.
The AU-SERVER class rejects all other HTTP/HTML commands.
