Monitor - Pools Page

From this page, you can view the pools that are configured for a particular server, and by selecting a particular pool, see a list of sessions associated with that pool. Choose a session to see the Session Monitor. Choose Change State to start or stop your pool.

To display the Pools page, in the left pane of the MCS window, select a server and choose Monitor. In the right pane of the MCS window, select the Pools tab.

Sessions exist in one of three states:

Inactive: The session does not currently exist, but a pool has been configured to contain a maximum number of them. This number is the inactive number of sessions in a pool.
Free: The session is connected to the host and free to be used by a client application.
Allocated: The session is connected to the host and currently in use by a client application.

Select Pool to Monitor: Each pool is listed, along with pertinent information to help you monitor the pool. Data is reset when the pool is stopped.

This column
Describes this

Name The name of the pool. This is usually the same name given to the project (NavMap) the pool is associated with.

State This indicates whether the pool is currently running. The pool is either starting or stopping.

Inactive The number of sessions contained in a pool that are available to be allocated (up to the maximum value). The initial number of sessions available to a pool as well as the maximum number are set on the General Configuration page. 0 or "unlimited" indicates that an infinite value has been set.

Free The number of sessions that are connected and available for use by the next client application. Free sessions are available for the next request that comes in.

Allocated The number of sessions currently allocated to and in use by client applications.

Max allocated This is the peak number of concurrent session allocations for a single pool since the Runtime Service was started. For example, if you set up a pool containing ten sessions, and over the duration of the pool, the most sessions ever used concurrently was 8, then the max allocated value is 8.

Total allocated The running count of sessions that have been allocated for a single pool since the Runtime Service was started. This number can exceed the max allocated value, as well as the maximum number of sessions set on the General Configuration page. For example, during the lifetime of a pool, a number of sessions can be allocated, freed, and then re-allocated. The total number of these allocations is recorded here.

Allocation failures The number of client application requests that were denied since the Runtime Service was started.

Creation failures The number of sessions that were unable to initialize since the Runtime Service was started. These are failures that occur when attempting to connect to the host, such as the logon process failed.

When you choose a pool from the list, the sessions belonging to the pool are listed in the Select Session to Monitor pane.

Change State: Starts or stops the selected pool.

In order to change some pool configuration options, you must first stop the pool.

Select Session to Monitor: Displays all the sessions, including pertinent information to help you monitor the session.

This column
Describes this

ID Unique session number, assigned by the pool.

Navigation The navigation state of the session, for instance, idle or navigating.

Elapsed Time The time the session has been in its current state.

State The availablity of the session: free, allocated, or inactive.

Host The address of the host associated with the pool containing the selected session.

Job Name The job name is designated on the Session Monitor: Advanced page and is imperative for correlating events with tasks when logging events. See Correlating Events with Tasks Using Job Names in the Related Topics list for more information.

Instance Name A user-defined instance name, such as an identifier for the bean on a Web page, or other bean container. This name does not need to be unique. The default value is an empty string.

Allocations The total number of client applications that have been allocated to this session.

Errors The number of errors that have been encountered during this session.
