Web Intelligence Session Timeout

[Former Member]

I am running Business Objects XI R2 SP2 and running Xcelsius 2008 FP1.

Basically within my models i use LiveOffice to refresh the initial data used within the models and then I use QaaWS to use certain drill through parameters to retrieve more detailed information.

All this works fine and returns all the data i need, but i get session errors when accessing the models from Infoview.

When i log into Infoview, i can run 1 model fine and do all the necessary refreshes and further drill downs without any trouble, but when i close the model down and try to go into the next model i get the following error message;

Your webintelligence session has timeed out WIS: 30553.

NOw i have updated all the setting i know of eg;

1) Webi report server timeout in server properties

2) Configured the command line of the webi report server in CCM to include the timeout parameter.

3) Web.xml file has been amended to increase the session timout

4) Web.xml file has been amended to uncomment the listener settings

5) i have even updated the session timeout on the Tomcat server (tomcat\conf\web.xml)

Has anyone any other ideas as i can not access the models

If the previous solutions provided are not helpful then you can try the following one.

You may have to increase the default time-out value for persistent HTTP connections in Internet Explorer if you are using a Web program that must communicate with Internet Explorer over the same TCP/IP socket after one idle minute. To change the default time-out value for persistent HTTP connections in Internet Explorer, add a DWORD value that is named KeepAliveTimeout to the following registry key, and then set its value data to the time (in milliseconds) that you want Internet Explorer to wait before resetting an idle connection:

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\InternetSettings

To do this, follow these steps:

1.Click Start, click Run, type regedit, and then click OK.

2.Locate and then click the following key in the registry:

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\InternetSettings

3.On the Edit menu, point to New, and then click DWORD Value.

4.Type KeepAliveTimeout, and then press ENTER.

5.On the Edit menu, click Modify.

6.Type the appropriate time-out value (in milliseconds), and then click OK. For example, to set the time-out value to two minutes, type 120000.

7.Restart Internet Explorer.

If you set the KeepAliveTimeout value to less than 60,000 (one minute), you may have problems communicating with Web servers that require persistent HTTP connections. For example, you may receive a "Page cannot be displayed" error message.

If you must have a KeepAliveTimeout value higher than 120000 (two minutes), you must create an additional registry key and set its value equal to the KeepAliveTimeout value that you want. The additional registry key is ServerInfoTimeout. It is a DWORD with a value (in milliseconds) and in the same location as KeepAliveTimeout.

For example, to use a three-minute KeepAliveTimeout value, you must create the following registry keys:

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\InternetSettings

KeepAliveTimeout DWORD value 180000 (in milliseconds)

ServerInfoTimeout DWORD value 180000 (in milliseconds)

By default, HTTP 1.1 is enabled in Internet Explorer except when you establish an HTTP connection through a proxy server. When HTTP 1.1 is enabled, HTTP connections remain open (or persistent) by default until the connection is idle for one minute or until the value that is specified by the KeepAliveTimeout value in the registry is reached. You can modify HTTP 1.1 settings in Internet Explorer by using the Advanced tab in the Internet Options dialog box.

Hi Sarbhjeet,

I did find your previous post on this, but the trouble is, the session is not inactive at all. i click into 1 model and then come striaght out and click into the next one and the error message is displayed.

When i go into webi reports i can move around without an issues at all. I can open up a report refresh it, close it down and go into another report and refresh and all is ok, so i think it is related to Xcelsius??

Hi Anthony,

Following solutions might be helpful for resolving the issue.

Solution1:

If you are using .net, please perform following settings

- Right mouse click on "My Computer" and select "Manage"

- Expand "Services and Applications"

>> "Internet Information Services"

>> "Web Sites"

- Right mouse click on "Default Web Site" and select "Properties"

- Increase "Connection Timeout" from 120 seconds to 3600 seconds

- Next click the "Home Directory" tab and click the "Configuration" button

- Under the "Options" tab, increase the ASP Script timeout to 600 seconds

Solution2:

Go to Start > Settings > Control Panel > System > Advanced > Enviromental Variables and under both User and System variables change the TEMP and TMP variables to the same location.

Solution3:

Click Start > Run. The Run dialog box appears.

Type "regedit" in the Open text field. Click OK. The Registry Editor appears.

Navigate to the HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Control/Session Manager.

Click Subsystems > right-click Windows key > click Modify.

Edit the SharedSection value from 1024,3072,512 to 1024,3072,1024.

Solution4:

Webi Report Server

Enable the following

• List of values caching

• Enable Viewing Caching

• Enable Real time Caching

- Increase 'Document Cache Duration'

- Increase 'Document Cache Size'

- Increase 'Document Cache Scan Interval'

- 'Document Cache Duration' should always grater than 'Document Cache Scan Interval'

I hope this will help you.

Hi Sarbhjeet,

I have tried everything you have listed above and i still get the error message. What is strange is that i have to shut the browser down and log back into Infoview to gain access.

I can not use the log on button and log back in as when i do that i get the error when i click on the first model.

regards,

anthony
