Filtering your Session

You can filter the displayed sessions in the ApplinX Administrator by

See screen below:

graphics/filter.png

Two types of filtering are supported:

Define a filter and press Enter or click the Filter button to activate the filter. The filter specification appears near the table in the node information area.

When a valid filter is properly applied, the background color of the filter area is colored light orange:

graphics/filter-active.png

If you are filtering by duration, the filter is validated. If it does not match one of the allowed formats ("x day(s)", "hh:mm:ss" or value in seconds) a red border is created around the text field, indicating the value is not allowed.

graphics/filter-red.png

When you modify active filter, the color changes back to indicate that the filter line and active filter box are not the same.

Start of instruction setTo remove the filter

Setting the Refresh Rate

By default, the session list is sampled every second in order to keep it updated. When many users connect to the server, this refresh rate can significantly slow down the list’s update. You can change the system’s refresh rate to suit your needs.

Start of instruction setTo set the Refresh Rate

  1. Open ApplinX Administrator.

    Right-click on the Management>Current Activity>Sessions node and select Refresh Rate. The Refresh Rate dialog box appears.

    graphics/RefreshRate.png

  2. Type the new Refresh Rate in milliseconds, click OK.

The Refresh Rate is changed, and you may read all updated data from the server in the desired frequency.

Accessing the Session Viewer

This feature allows you to view the current host session while you are in the Administrator. The benefits of this feature are that it allows you to view the current host screen at the same time as other users are viewing the same host screen. If you are experiencing problems in code, the Session Viewer allows you to view the current host screen.

To access the Session Viewer, open ApplinX Administrator and select the relevant session in the Main View, then either right-click on the session and select Show Session or select Show Session in the Connection menu.

Canceling a Session

Using the Administrator, you can cancel a session from the server. This is useful when:

Note:
You can use session filtering to cancel multiple sessions in one operation. See Filtering your Session above.

Start of instruction setTo cancel a session on the server

  1. Open ApplinX Administrator.

  2. Select the relevant session in the Main View, then either right-click on the session and select Cancel Session or select Cancel Session in the Connection menu.

  3. Click Yes in the Cancel Session dialog box appears.

Managing Connection Pools

Note:
Refer to the Administrative Web Services API to access connection pool information using the API.

Viewing Application Connection Pools

To view a list of all Pools whose applications are loaded open ApplinX Administrator and select the Management>Current Activity>Connection Pools node.

Application/Connection Pool

The name of the application followed by the full name of the Connection Pool.

Example Value

Demo:/folderA /ConnectionPoolName

Status

Current status of the connection pool:

"Not Started"- The connection pool was not initialized yet. If a user requests a connection the connection pool will return an immediate error.

"Initializing" - The connection pool is trying to reach Active status, but does not have any ready connection yet. If a user requests a connection the connection pool will return an immediate error.

"Active" - The connection pool is working, and managed to create at least one connection to the host.

"In standby" - The connection pool had several consecutive errors trying to create new connections to the host. The connection pool will continue to try to connect if user requests arrive, but will not initiate new connections otherwise. If a new connection is successfully created, the status will automatically change to Active.

"Suspended" - The connection pool is blocked for new users, and does not maintain its connections. If a user requests a connection the connection pool will return an immediate error.

"Stopping" - The connection pool is trying to reach Stopped status, but still has connections in different stages of termination. When all connections are down, the status will automatically change to Stopped. If a user requests a connection the connection pool will return an immediate error.

"Stopped" - The connection pool does not have connections or maintenance. If a user requests a connection the connection pool will return an immediate error.

Active

The number of connections in use (with users attached).

Example Value

10

Ready

The number of available connections.

Example Value

5

Process

The number of connections currently in one of the following states: initializing, recycling or keep-alive.

Example Value

1

Viewing Connection Pool Monitoring Information

To view the run time information about a specific connection pool, open ApplinX Administrator and select the Management>Current Activity>Connection Pools node and then either double-click the required connection pool in the Main view area or right-click the required connection pool either in the ApplinX Explorer or in the Main view section and select Show Monitor.

This panel displays identifying information about the displayed connection pool.

Name

The name of the displayed connection pool.

Folder

The folder in which the displayed host connection pool is placed.

Application

The application to which the connection pool belongs.

Current State

This panel displays run time information about the displayed connection pool.

Since

The connection pool is in its current status since this time.

Connections

The total number of connections in the connection pool, ignoring broken connections.

Broken

The number of connections that failed initialization recently. When more than 0, this number is shown in red.

Average wait time

The average time (in milliseconds) sessions waited for a READY connection (calculated only among those sessions that waited) multiplied by the percentage of waiting sessions. For example: if 8% sessions had to wait, and in average each of those waited 1000 milliseconds, the overall average wait time was: 0.08 * 1000 = 80 milliseconds.

Sessions served

The total number of sessions that connected to the connection pool since the connection pool started.

Connections used
