This page shows you information on the transaction manager service instances.
Navigation: Site Map > Transaction Managers (under Application Services)
The following information is displayed:
Details (Show/Hide) - Click Show to display the Sleep Interval setup for the selected Transaction Manager and the percent Estimated Availability. The sleep interval can be edited by clicking the Edit button.
Name - Drills down to the Service Instances Processes page.
Status - drills down to the Status page for the selected transaction manager.
State - The current state of a service. If you perform an action on that service, the state column value is updated.
Node - In a parallel concurrent processing environment, a service's processes are targeted to run on the node displayed here. If a service is defined to use a platform-specific system queue, this column displays the name of the queue to which the service submits its processes.
Actual Processes - The number of operating system processes. Typically, the number of actual processes equals the number of target processes (the maximum number of requests a service can run). However, the number of actual processes may be less than the number of target processes due to service deactivation or service migration.
Target Processes - This column displays the maximum number of service processes that can be active for this service.
Timeouts - the number of timeouts that have occurred for this manager since its last activation.
You can use the buttons at the top to perform the following on a selected service instance:
Delete
Edit - Launches the Edit Manager page.
View Status - Launches the Status page.
View Processes - Launches the Service Instances Processes page.
To create a new service instance, use the Create New button.
Use the drop-down list to set the debug level for the transaction manager. Choose one of the following options and click the Set Debug Level button. This will set the debug level for all Transaction Managers and will be enabled for future sessions.
Client side debugging
Both Client and Server side debugging
Server side debugging
Off
Note: Because debugging can adversely affect performance, it is important to turn it off when you are finished.
If a transaction manager is performing poorly, use the Time Transaction Manager feature to help diagnose the source of the problem. The Time Transaction Manager test reports the time consumed by each activity involved in a single transaction.
To run the test, select a transaction manager and click the Time Transaction button. This will invoke the Time Transaction Manager launch page. Click the Run Test button. The test results page will display the following information:
Elapsed Time - the total time required to complete the test.
Program - the test program name.
User - the user ID of the initiator of the test. Drills down to the User Details page.
Session ID
Transaction ID
Time - the time the activity began.
Source Type - the type of activity and whether it was initiated by the client or the server. If you activated client-side only or server-side only the test will show only those activities of the selected source. To see both, select Both Client and Server side debugging.
Action - description of the activity
Message - any message returned by the activity
Function - the PL/SQL function
Elapsed Time (in hundredths of seconds)
From this screen, click Finish Test to return to the Service Instances page, or click Purge to purge the debug information for the session.
You can select a service instance and use the drop down menu above the table to perform the actions listed below. Or you can use the drop down menu at the top right to perform a single action on all service instances.
Starts (activates) a service instance.
Deactivates individual services. Once deactivated, a service does not restart until you select the service and choose the Start button.
When you deactivate a manager, all transaction requests currently running are allowed to complete before the manager shuts down.
When you restart a transaction manager, its processes are shut down and then brought back up.
Aborts or terminates individual services.
