Measures reported by TuxedoServerTest

An administration server is a software program that performs administration functions. Each Tuxedo managed node has the following administration servers:

  • BRIDGE: An administration server that establishes the machine's listening address.
  • BULLETIN BOARD LIAISON (BBL): An administration server that creates the shared memory Bulletin Board. Each master machine also has a Distinguished Bulletin Board Liaison (DBBL), which is an administration server that manages the updates to the Bulletin Board.

A Tuxedo managed node may have additional administration servers, such as Transaction Management Server (TMS), which handles transaction completion.

Failure of a critical administration server such as BBL can cause the activation of other administration servers on that machine to fail. If the DBBL fails to activate, the entire application's activation process will fail. It is hence imperative to continuously track the state of each administration server.

This test reports the current state of and the load on every administration server on the target Tuxedo server, so that server failures and improper load distribution amongst administration servers (i.e., services) are detected early and fixed.

The measures made by this test are as follows:

Measurement Description Measurement Unit Interpretation
Service_state Indicates the current state of this administration server.   The values that this measure can report and their corresponding numeric equivalents have been detailed in the table below:

Measure Value Numeric Value
Active 100
Idle 1
Inactive 0

Note:

By default, this measure reports the Measure Values discussed in the table above to indicate the current state of a server. The graph of this measure however, represents the same using the numeric equivalents only.

Request_handle Indicates the number of requests handled by this administration server during the last measurement period. Number  
Load_server Indicates the load on this server during the last measurement period. Number Compare the value of this measure across servers to identify the server that is overloaded.
