1.1 Overview
MidJet GSM Text is a robust interface to the Short Message Service (SMS)
offered by all major GSM network operators. It provides the capability to
exchange up to 160 characters long text messages, between iSeries and
GSM telephones.
The main functions are:
- A user-friendly paging system, with ability to create and send SMS
messages to individual person(s) or group(s) of persons.
- A solid monitor for operational problems. MidJet GSM Text will send a
message when a batch job halts with MSGW status, or if a message
arrives at a message queue. Thus system messages like multiple
attempts to sign on with incorrect password, application program errors,
communications problems, running out of disk space etc will be
forwarded to the operator in charge. Messages can also be sent as e-
mail using GSM Text’s integrated SMTP client.
For inquiry messages, a reply message can be sent from the GSM
telephone back to the iSeries. After an authority check, the message will
perform a reply to the message in the message queue. In addition, the
second level (help) text can be forwarded to the mobile phone.
Using the design of checkpoints, a number of different conditions can be
controlled. MidJet GSM Text checks the iSeries to ensure that certain
subsystems and jobs are active when they should be. Job queues and out
queues can be monitored in order to check that only an allowed number of
entries exist. Connection checks to remote systems or other units using
TCP/IP is supported. Configuration objects, lines, controllers, devices or
network interfaces descriptions can be checked for an accepted status. The
accessibility to HTTP, POP3, SMTP and generic servers can be checked. A
user written program can be used to check other conditions.
The operations monitor offers the possibility of message escalation. When
this is active, operational messages will be sent to the next person in a
distribution group when no attention was paid by the first receiver.
With the use of the included API’s, the user defined question and reply
handling function is enabled. This makes it possible to use the GSM
telephone as a device to issue inquiries to the database and receive replies.
A source file with example programs illustrates the ease of using the API’s.
When an iSeries operational message is sent to the mobile, it is possible to
use the modem to ring the mobile phone afterwards. The intended use is to
alert the operator in charge during night time etc. This function is called
”alarm call”.
The application creates logs where sent and received messages can be
retrieved. The logs contain all important information about each message.
There is also an API that can be used to retrieve message information from
within your own application.
The MidJet Win2000/NT Monitor product allows you to perform the similar
operations monitoring on systems the Microsoft Win2000 and NT operating
systems. Entries in the Event Log can be selected and transferred, and
predefined processes can be controlled active. As an option, user log files in
text format can be monitored. Commands can be run, initiated from the
