I dont use App connectors much so I won’t be able to help you much.

Just a thought – were you able to reproduce this behaviour of Office 2007 and Office 2003 with Webtop running on your local PC? That could help to identify if the problem is with Office product or if some proxy/webserver redirection is causing this issue.

cheers.

I’ve a strange situation. MS Word 2007 works good with application connector D6.5. But when using MS Word 2003 I get the “ucf session wait timeout” error.

Any idea? Thanks in advance.

Anton

I’ve never had to test this setting (didn’t have to use it as we have acceptable performance on a D6SP1 platform) but there is some client.engine.timeout setting in the ucf.client.config.xml that one can use to keep the ucf java process awake for more than the default 1 minute setting. Now it must be that the java process is stopped if you close your internet explorer window (did not test that).

Thanks for sharing the information. I have heard about the improvements in D6.5. Unfortunately these improvements are not ported to D6 SP1. So organizations who have recently upgraded to D6 will face the UCF lag issues.

I came to know that efforts are ongoing to port the D6.5 performance enhancements to D6 SP1 and provide a hot-fix. Lets see how that goes.

As you know the problem of this lag is mostly due to JRE initialization. But to the end-user who just wants to use Documentum, the lag is perceived to be with Documentum. Hopefully the future version of Sun JRE will launch faster…

cheers

For info, D6.5 has considerably better UCF performance. The JRE is initialised on user login to Webtop and persists. Therefore the”lag” on document download is much, much less. On local testing on a laptop, if I have (say) Word or Acrobat already open, then select a PDF/DOC (say 250Kb) to view in Webtop it almost instantly opens in the native application.

My laptop is running Sophos AV BTW and is not setup to ignore any files.

FROM THE WHAT’S NEW IN 6.5 PDF:

UCF performance improvements in Webtop

UCF content transfer is more usable and performs better. The following lists the UCF
enhancements for Documentum 6.5:
• Reduction in the number of round trips between the UCF client and server. This feature is especially effective for improving transfer performance for smaller files over a high latency WAN.
• The following UCF client initialization/startup improvements:
— Sharing a JVM instance across multiple web sessions
— Starting JVM upon login
• Support for PDF byte streaming through a native viewer.
• Use of parallel streams to increase content transfer rate. This feature is especially effective for improving content transfer performance of large files over a high latency WAN (outbound and inbound).
• Freeing up stuck threads to optimize resources and increase concurrency.
• Reduction in unnecessary WDK UCF client calls.

Content transfer dialog
———————–
An improved content transfer dialog shows the action that is running (in the header of the dialog), the file which is transferring at the time, and progress of that transfer. The new dialog is easier to understand and is similar to other applications with which a user may be familiar
