How to adjust timeouts in FlexiCapture

If you are looking to adjust the following Timeouts:
Inactive Session Timeout
Timeout for Postponed Tasks
Timeout for Deferred Rescan Tasks
Timeout for Tasks assigned to a Specific User

This article is the right one for you.

All of the mentioned timeouts need to be configured on the application server machine (on the computer where FlexiCapture Server is installed) in IIS (Internet Information Service)

To revoke a task during the verification while the user is inactive, you need to configure the main server timeout - the lifetime of an inactive session.

It is important to remember that the timeout affects not the tasks, but the session – in case the station freezes or there is no user activity, the session will be deleted after the timeout. (The processing server starts cleaning once an hour. It accesses the application server, which in turn deletes all sessions with an expired timeout).

The timeout acts at the stations:

  • Verification and data verification stations, local and remote ones
  • Project Setup Station

Step-by-step guide

The timeout is configured on the application server machine (on the computer where FlexiCapture Server is installed) in IIS (Internet Information Service)

Inactive Session Timeout Setup

Timeout settings are stored at \FlexiCapture12\Server\web.config - <appSettings> (\Default Web Site\FlexiCapture12\Server - Application Settings:

1) Open Administrative Tools (Control Panel\System and Security\Administrative Tools) and choose Internet Information Service (IIS) Manager:

2) In the IIS Manager choose FlexiCapture Server (Sites -> Default Web Site -> FlexiCapture12)

3) Choose Server Folder and open Application Settings in the right side.

4) Change the value of the key InactiveSessionTimeoutMinutes at Application Settings – timeout value in minutes (in case you don’t have such key there, add it).

Please note that server cleans expired sessions once an hour.

In case the timeout at the thick station has expired, after trying to make changes to the task you will receive a message that the session is closed.

Timeout for Postponed Tasks

Is configured on the application server in IIS as well.

\FlexiCapture12\Server\web.config - <appSettings> (\Default Web Site\FlexiCapture12\Server - Application Settings) (see steps 1-3 in Inactive Session Timeout Setup)

In Application Settings, change the value of the PostponedTaskExpirationMinutes key (if there is no such key, then you need to add it). This applies to the whole complex. The value is how many minutes you can keep the verification task pending. The default value is 0 (cleaning off). If cleaning works for a task, it returns to the queue and event 28 “task return from deferred” is written to the log. Edits to the task that were saved to the server are not lost during the process, and then the operator will have the opportunity to either commit or roll them back.

Timeout for Deferred Rescan Tasks

It is configured on the application server in IIS as well.

\FlexiCapture12\Server\web.config - <appSettings> (\Default Web Site\FlexiCapture12\Server - Application Settings) (see steps 1-3 in Inactive Session Timeout Setup)

In Application Settings, change the value of the RescanningTaskExpirationMinutes key (if there is no such key, then you need to add it). Similar to PostponedTaskExpirationMinutes, but for deferred rescan tasks. The processing server performs cleaning once an hour; within each cleaning, it first cleans the verification tasks, then rescan ones.

Timeout for tasks assigned to a Specific User

Configured on the application server in IIS as well.

\FlexiCapture12\Server\web.config - <appSettings> (\Default Web Site\FlexiCapture12\Server - Application Settings) (see steps 1-3 in Inactive Session Timeout Setup)

In Application Settings, change the value of the PersonalTaskExpirationMinutes key (if there is no such key, then you need to add it). Similar to PostponedTaskExpirationMinutes, but for tasks assigned to a specific user. After this timeout, the task is returned to the shared pool.

Verification Web Station Timeout

Verification Web Station Timeout is configured separately at \Default Web Site\FlexiCapture12\Verification.

This timeout only affects web stations (it does not affect thick stations).

Configuration steps:

1) Open the Administrative Tools (Control Panel \ System and Security \ Administrative Tools) and select the Internet Information Service (IIS) Manager:

2) In the IIS Manager, select the FlexiCapture server (Sites -> Default Web Site -> FlexiCapture12)

3) Open the Verification folder and select Application Settings on the right

4) In Application Settings, change the parameter values
SessionInactiveLifetimeInMinutes - timeout for tasks in minutes (default value is 120 minutes)
SessionRefreshInterval - check interval in milliseconds (default value is 60,000, i.e. 1 time per minute)
If there are no such keys, then you need to add them

Warning! In case a timeout is configured on the server (the lifetime of an inactive session), after the server timeout expires, the web session will show verification errors and prevent the open task from being saved.

In case a web timeout is configured, after it expires, the web page will simply switch to the login page.

    I have followed the steps above for the inactive web verification (changed the timeout to 20 minutes) but I still have an issue with empty sessions piling up.  Have also reached out to the VAR but they don't have any additional help besides the step listed above as well..  

    We are using version 12.0.3.2525
