Big advantage of the PVSS Web Client

Post by smass »

Did you know about the big advantage of the PVSS Web Client? :

Apart from the fact that it runs in a webbrowser, the panel files, message catalogs and config-files of the server are locally cached at the client and automatically kept up to date!
No need to copy any files manually.

Even if you use a Standard User Interface instead of the WebClient, you can call it with the following option to also use the caching mechanism (you must have the http-server for the PVSS Web Client running on the server side):

PVSS00ui -server

Apart from the caching mechanism another advantage is, that you need no network-share for the files and no open ports for the event- and datamanager in your firewall because the connection is established via port 80.

"Share the fun!"

Dear Sebastian,

It would be good to let people know that a license is needed for the use of the HTTP-connection.

With regards,

Martijn Goedhart

Thank you for your input Martijn!

You need one webclient license for each webclient you want to use simultaneously
(just similar to the usual UI licensing - you have to use a floating UI license for every UI you want to use at the same time)

For the http-server to which the webclients connect, you need only ONE license on the machine where the control-manager for the http-server is running (not a license for every connection)

Dear Sebastian

I have implemented -server option for all our Clients and Webclients and am impressed.
This saves me implementing other methods to update panels/msg/etc etc. prior to this I had batch files running between servers/clients

Only issue I have with the webclient would be to have a more friendly interface as standard for when the number of licenses used from the 'server' has been exceeded/used.
Operators find this difficult to understand.
I have implemented a script to auto logout webclients after an inactivity delay, only if they operate in a web browser.

Sebastian,

On the web client all files of all subprojects and the project are merged into one folder structure. How will this influence the config files, eg. config.level? Will a webclient load all the necessary libraries?

Thank you for your input Jason, i'll take this into account.
Your script for the auto logout might be a good article for our "Lab" in the Portal - do you want to participate? ;-)

The HTTP Server always merges all config/config.level/config.redu/... files as needed and sends this to the client.
Have a look into the clients /config/config file and you'll find the merged config file with delimiter lines between the
separate files on the server, e.g.:
## /opt/pvss/pvss2_v3.9/config/config.level ##

The merging is done inside the HTTP Server script - you can have a look into the getConfig() function.

Does the PC clock on the client and server PC still has to be synchronized?
