[UNIFACE-L:2063] RE: iPlanet and URD threads

[LOPER, LOUIS M (AIT)]

I ran into this problem with Iplanet about two years ago and I believe that
there is no possible
way to get more than one WASV to run. The uniface lab knows about the
problem, but they were
unable to determine if the problem is related to Uniface or Iplanet servlet
engine.
I could never get more than one WASV process to run on the server, I worked
with several
technician from Netscape, but they knew absolutely nothing about Uniface and
did not want to
learn. I made the decision after all of the frustration to use Iplanet 4.1
as my webserver and IBM
Websphere 3.5.6 as my servlet engine. The Iplanet - Websphere combination
has worked well for us.
If you have any questions, please let me know.....

P.S. I ran into this problem in both Uniface 7.2.05 and 7.2.06. I could
also probably track down
my old call tracking number if you need it.

Thanks,

Subject: [UNIFACE-L:2048] iPlanet and URD threads

We have a customer who is running iPlanet on Unix with the java
servlet URD(7.2.06) but they only ever appear to have one servlet
thread running and consequently a single WASV process, which leads to
poor throughput because every request is serialized through this one
servlet.

We can see that when we use Tomcat that multiple requests are handled
by multiple threads in the URD and hence multiple WASVs.

We don't know iPlanet, so are limited in our ability to help, but have
suggested everything in the iPlanet documentation with regard to java
servlets and threads, but to no avail.

Does anyone have any experience of running the URD on iPlanet that
could give spare some hints and tips on how to make it multi-threaded?

Thanks.

Hello Lou and Andy,

Overhere we are working with Iplanet4.1/Solaris and the java servlet
URD(7.2.06) and ran into the same problems about the single WASV
process. Instead of using websphere, we were advised to use JRUN 3.1
as servlet engine. Works fine in the situation of Iplanet+JRUN as
webserver environment and WASV process on the uniface application
server environment(other machine,Solaris) and when there is no
firewall between them (same DMZ). But with a firewall (Checkpoint)
between both machines, JRUN is not able to stop or clean up a started
WASV process. After a while of non activity and then another URD
request, JRUN wants to enable the started WASV again. But the firewall
has blocked the connection due to a non activity time out and the user
sees an empty screen within his browser. And after a while an Uniface
URD erro message. JRUN will not start a new WASV process unless the
user does a page refresh when he is confronted with an empty page.
It's a bugging and severe problem overhere and we are looking for a
solution for this. Transferring JRUN towards the application server
environment has been tried out, but then we run into problems with
serving out .JSP files from the Iplanet webserver environment since
JRUN wants them on the same machine as were JRUN is running.

Perhaps you, or someone else, can be of any assistance for us?

Thx,

René Haring, CR Delta the netherlands

Has any-one tried iPlanet 6.x with the URD servlet?

In reading the documentation there appears to be a "number-of-singles"
parameter setting to specify the number of SingleThreadModel servlet
instances can be created.

Seems like the ticket, except we have no way of testing it.
