Measures reported by TuxedoTransTest

The BEA Tuxedo transaction management server, named TMS, is responsible for coordinating global transactions, on behalf of BEA Tuxedo applications, from their point of origin-typically on the client-across one or more server machines, and then back to the originating client. TMS tracks transaction participants and supervises a two-phase commit protocol, ensuring that transaction commit and rollback are properly handled at each site.

To measure the load on the TMS, you need to know how many transactions are being handled by the TMS and what is their current state - whether they are being committed? rolled-back? aborted?. This can be achieved using the TuxedoTransTest. This test reports the number of transactions currently handled by TMS, and reveals the state of each transaction.

The measures made by this test are as follows:

Measurement Description Measurement Unit Interpretation
No_of_transactions Indicates the number of transactions currently handled by the server. Number A high value for this indicates heavy load on the TMS. To know which transactions are currently being serviced by TMS and what their status is, use the detailed diagnosis of this measure. The detailed diagnosis reveals the Global_Transacation_Identifier, Machine_Id, Transaction_status, and Group_count. A transaction can be in of the following states:

  • TMGACTIVE
  • TMGABORTED
  • TMGTOBEABORTED
  • TMGCOMMITED
  • TMGCOMMITCALLED
  • TMGDECIDED
