Configuring the Enterprise Message Bank
The Enterprise Message Bank is an optional remote archiving facility where you can collect messages, Event Log items, and search table entries from multiple Ensemble client productions.
This chapter describes how to configure it. It discusses the following topics:
The following chapter Identifying Enterprise Systems for Viewing and Monitoring, describes how to configure enterprise systems so that you can resend messages from the Message Bank.
For information on defining the Enterprise Message Bank, which is a specialized Ensemble production, see “Defining an Enterprise Message Bank” in Developing Ensemble Productions.
For information on using it, see “Using the Enterprise Message Bank”’ in Monitoring Ensemble.
You must configure each desired client production to send messages to the Message Bank. For each client production, perform the following configuration steps:
Add the specialized message bank operation (Ens.Enterprise.MsgBankOperation) to the production and configure it as needed.Note:For this business host, Operation Name must be the Message Bank operation class name. Either leave this blank to use the default class name or enterEns.Enterprise.MsgBankOperation.See the following subsection for configuration details.
If you have not yet done so, configure the link to the Message Bank, as described in the previous section.Or navigate to the Configure Message Bank Link page (Ensemble > View > Enterprise Message Bank). The first time you enter the Enterprise Message Bank page, Ensemble prompts you for information to define the link. This information is the same as described earlier.
Now the production is configured to send messages to the Message Bank, and the Management Portal has a link to the Message Bank web pages.
Configure the following settings specifically for the Message Bank:
Set to True. This starts messages queuing from all business hosts in the client production. Note that this queueing continues even if you disable the operation and while it is not able to connect to the Message Bank. The operation forwards any queued messages to the Message Bank server whenever it is enabled.
If set to False, the operation does not queue any messages for the Message Bank.
IP address of the Message Bank production. Note that this does not include the web server port number.
TCP port number used by the Message Bank production input service (9192 is the default).
Optionally configure the following additional settings:
Controls which messages to send to the Message Bank. The default behavior is to archive everything except scheduler messages as shown by the value:
See the following subsection.
Event Log Interval
How frequently should we check for conforming Event Log events that may need to be forwarded to the Message Bank server. 0 means check only when messages are being forwarded.
If set to True, send empty event submissions periodically if no conforming events need to be submitted.
For information on other settings, see the following:
“Settings in All Productions” at the end of this book.
The Archive Items setting controls which messages the production sends to the Message Bank. It is a comma-separated list of configuration names of items whose messages are to be archived to the Message Bank server.
Archive log events for each item using the following colon-separated syntax:
Within the event type brackets, you can use the following characters in your selection list:
|Pattern character||Placement||Resulting action|
|include all event types|
|at the front of an item||exclude the type from archiving entirely|
|at the end of an item||exclude message bodies from archiving|
|at the end of an item||exclude search table entries from archiving|
|at the end of an item||exclude message headers from archiving|
|for events of type Trace||optionally used to select a particular category of trace event. Event type Trace without a suffix means Trace events of all categories.|
*[*]— Archive everything
*$[*],Ens.Alert![-*]— Archive all events, headers, and bodies but not SearchTable entries; but do not archive bodies or events from item Ens.Alert.
Ensemble only archives trace events if it has logged them. You can use these settings only to restrict which logged events get archived, not to archive any events that you did not configure to be logged.
The Ens.Enterprise.MsgBank.TCPService component on the Message Bank server helps process the incoming messages from the Message Bank client productions. If you have configured enterprise systems, the TCPService uses the information that you defined to associate the incoming message with the enterprise system. See “Identifying Enterprise Systems for Viewing and Monitoring” for details on configuring enterprise systems. If you do not identify the enterprise system, the monitor service identifies the incoming message based on the elements of the message.
There are two cases where it there may be conflicting information to identify the enterprise system sending the message:
If the enterprise system has multiple IP addresses and the system restarts it may be sending messages from a different IP address. To instruct the Message Bank to recognize that these messages are coming from the same enterprise system as the earlier messages, select the Ignore Client IP Changes check box on the Ens.Enterprise.MsgBank.TCPService.
Although it is not a recommended configuration, it is possible to terminate an enterprise system and restart a new one with the exact same configuration and name but resetting the message IDs. Since the message IDs are not related to the ones in the messages sent by the previous enterprise system, the Message Bank should treat it as a new enterprise system. In this case you should clear the Ignore Client IP Changes check box on the Ens.Enterprise.MsgBank.TCPService.
The Ignore Client IP Changes check box does not affect how the Message Bank treats enterprise systems that are part of a Caché mirror set (see “Mirroring Architecture and Planning” in the Caché High Availability Guide).
