Iisproxy.dll & Performance

The installation guide for the WebLogic-to-MS-IIS Bridge includes two
screen shots that display a disabled "Cache ISAPI applications" and an
enabled "Run in separate memory space (isolated process)". Since there
are performance implications with these settings, I am wondering if
these settings are recommended?
Thanks in advance.
Namaste,
Michael

We're running a B-to-B web app with WL 5.1 with service pack 6 on NT 4.
When we hit Weblogic server with a browser directly (not using IIS at all), we get
good performance across all of our JSPs. However, when we use IIS to proxy (all .jsp
file extensions) to Weblogic, for some reason performance decreases sharply (2-5
times slower under load), especially for large JSP responses. IIS is running on a
separate box, and we've reviewed all the performance tuning guides we can find and
believe we've optimized as best as possible.
We tried running IIS on two boxes, each proxying to the same Weblogic instance running
on a third box; this improved performance by 40%, leading us to believe that iisproxy.dll
and/or IIS on the web server is becoming the bottleneck for our application.
Anyone have any tips or advice for improving the throughput of iisproxy.dll?
Our iisproxy.ini is:
WebLogicHost=XXX.XXX.XXX.XXX
WebLogicPort=XXXX
ConnectTimeoutSecs=20
ConnectRetrySecs=4
Thanks,

Hi
we had also this problem on Solaris, and could solve it with using the
proxy from the SP8
hope it works on NT

IISProxy.dll error

This is the set up we have currently.
          Nt 4.0 server with IIS 4.0. I have followed the WebLogic 5.1 documentation
          and made the root web executable then mapped the extensions .jsp and .jhtml
          to c:\weblogic\iisproxy.dll.
          I have the iisproxy.ini in the c:\weblogic directory and it is a direct copy
          out of the documentation. We are getting an http 500 internal server error.
          When you hit refresh you get a %1 is no a valid windows nt application.
          I believe this problem is isolated to the IIS server.
          I had a sniffer on the network and at no time do I see any traffic from the
          IIS server to the Weblogic server. If I hit the Weblogic server explicitly
          it will server jsp pages.

The problem was a corrupted dll. Vinod was great in sending me a debug dll
          and it starting working. Once a fresh copy of the current dll was abtained
          and installed the servers are now talking.
          Thanks for all your help Vinod.

IP Address of Client after IISProxy.dll configured

Hi,
We have a requirement to capture IP address of client. we are able to do it when the users access the portal from inside the firewall using portal url. http://<servername>:port/irj
but when users access the portal outside the firewall we have IISproxy.dll configured which redirects requests from IIS server to our ep server. so everytime when we try to capture ip address we get the ipaddress of the IIS web server instead of user ip address.
one possible way could be get the ip address of the user on IIS server and send it as a parameter in redirected request to ep server.
Any suggestions?

In the XML Config file you have to have the following
<filter name="IisProxy filter" <b>remote-address="forward"</b>>
This will then forward the clients IP address to the J2EE server
I hope this helps

Iisproxy.dll problem

Hello all,
our group is having a problem with Weblogic's IIS plugin from the SP8 for WL5.1.
The plugin resubmits
long requests(queries) after about 5 minutes if the results don't come back from
the database in this
period of time, even though the ConnectionTimeoutSecs and ConnectionRetrySecs have
been set
to the same value, so it (the plugin) would never resubmit the request and would
time out after the
specified amount of seconds(according to the documentation).
But it does not work. Is there a bug in iisproxy.dll?
Any help would be appreciated.
Dmitriy.

ConnectionTimeoutSecs and ConnectionRetrySecs are more for the connection
between the client and the web server. They are used to calculate number of
connection retries with weblogic. HungServerRecoverSecs is the parameter you
need to play with. default=300 and max=600. It defines the timeout for reads
and writes
from/to weblogic. Note that plugin retries at least twice. Also you may
want to
set the parameter Idempotent to false in case you don't want failover at
all.

Probably the jsp was not proxied to weblogic and servered as raw html.
          I never used IIS 4.0, but I think there should be some configuration about
          the proxy on URL or mimes.

Iisproxy.dll throws DLL initialization routine has failed

Hi,
We are experiencing problems with the Weblogic ISAPI plug-in. After some time
the webserver is throwing the following error:
"A dynamic link library (DLL) initialization routine has failed" for all JSP requests
(the only ones that are using this plug-in), without crashing the IIS service.
This causes our load-balancers to hit the affected webserver(s) as the IIS service
is running, but the clients (browsers) only seen this error.
Our configuration is the following:
- 2 WLS 4.5.1 SP11 on Solaris 2.5.7 boxes running in a cluster
- 3 IIS4 using the iisproxy.dll from WLS 4.5.1 SP14 on NT4 SP6a boxes.
The plug-in is registered to only serve JSP requests and the "Run in separate
memory space" is checked. Does anyone knows what's the problem? I'm also attaching
the plug-in log.
Thanks in advance.
[Wlproxy.zip]

Thanks, JLS.
We figured it out. There's an entry in the registry that lvanyls.dll points to specifying the location of the LV shared directory (and therefore the MKL directory). If it's not found in that exact location, the dll load aborts.
We're trying to not include the runtime installer in our application installer because of the size, so we're figuring out our own workaround (and trying to CYA in the meantime ).

Iisproxy.dll causes "DLL initialization routine has failed" when serving JSPs

          Hi,
          We are experiencing problems with the Weblogic ISAPI plug-in. Often the webservers

Response Time out through IISProxy.dll

I just found that the end of my message was missing . So, I posting the remaining
over here.
Because , I was flusing the data after every 2 minutes , it worked fine ..
This one worked with WebLogic 5.1 when accessing the Weblogic server directly
. Like
http://IP:7001/x/applet.jsp (This JSP downloads the Applet under JRE1.3) .
From this Applet I was calling the above code (delay.jsp) using the HttpMessage
Class as given below.
However , when proxied by path with the WebServer IIS4.0 it didn't work.
IS IISProxy.dll not capable of doing it ?
Iam copying the code fragments for the Applet Iam using . Is it a problem with
the code?
I heard that the URLConnection never times out . How is that it is not able to
read the Response?
<CODE >
<HttpMessage>
public class HttpMessage {
URL servlet = null;
Hashtable headers = null;
public HttpMessage(URL servlet) {
this.servlet = servlet;
public InputStream sendGetMessage(Properties args) throws IOException {
String argString = ""; // default
if (args != null) {
argString = "?" + toEncodedString(args);
URL url = new URL(servlet.toExternalForm() + argString);
// Turn off caching
URLConnection con = url.openConnection();
con.setUseCaches(false);
// Send headers
sendHeaders(con);
return con.getInputStream();
private void sendHeaders(URLConnection con) {
if (headers != null) {
Enumeration enum = headers.keys();
while (enum.hasMoreElements()) {
String name = (String) enum.nextElement();
String value = (String) headers.get(name);
con.setRequestProperty(name, value);
</HttpMssage>
<Code used to Read the Response.>
URL url = new URL(getDocumentBase(),"/ccls/test/delay.jsp");
HttpMessage msg = new HttpMessage(url);
InputStream in = msg.sendGetMessage(null);
char[] buff = new char[2048];
int bytesRead;
int ch;
StringBuffer sbtextbox = new StringBuffer("");
DataInputStream data = new DataInputStream(
new BufferedInputStream(in));
String line;
while ((line = data.readLine()) != null) {
sbtextbox.append(line+"\r\n");
</Code used to Read the Response.>
</CODE>
Can anybody suggest what should be the possible reasons and any workaround for
it?

Increase "HungServerRecoverSecs"(default 300 seconds) in your iisproxy.ini.

It is working fine . However, if the response time of the server is more

the Response is not coming back to the the Applet and it is in a loop

I have observed that the request is sent to the server and it is processed

Then , I tried to call this sample JSP from the Applet.

out.flush();
System.out.println("2 Minutes");
dTime = System.currentTimeMillis();
System.out.println((new Date()).toString());

Regards, L.Mouillart

I implemented SSO succesfully with EP 6 SP9 using Windows integrated authentication. Used IISProcy 1.5.0.
It is two step prcoes.
1) Configure ISAPI filter for IRJ
2) Configure WebAS for Logon Module Stack. Create new module called HeaderVariableLoginModule.
Complete following steps.
1) Make sure you have IIS installed. Take a backup before the changes
2) Installl ISAPI filter called IRJ.
3) COpy IISPrxy files into the directory under Inetpub.
4) Map ISAPI filter IRJ to the IISProcy ditrectory.
5) Restart website to test ISAPI filter.
6) Please make sure to add logging for IISProcy filter. This gives very good info.
7) You can check the IisProxy.log file in the directory where you copied the IISProxy files.
8) CHeck and make sure REMOTE_USER is populated in the IisProxy.log file.
Configuration of WebAS server:
1) Create new login module called HeaderVariableLoginModule
2) Add this to the stack called ticket.
3) Change BasicPasswordLoginModule to optional.

Dll - performance issue

Hello,
I created a simple Vi to test the performance. It is very good - when I start the vi in LV both processors of my PC are used.
When I create a dll to export this funtion it gets very slow. When I use the function in Visual C it uses only one processor and therefore takes more time.
I attach a shot of the VI.
C.

Hi Curtis,
due to constant folding LV8.5 takes 0s to calc your SinCos vi!
I build a new dll from this, but didn't test it... Can you do so?
Best regards,
GerdW
CLAD, using 2009SP1 + LV2011SP1 + LV2014SP1 on WinXP+Win7+cRIO
Kudos are welcome

Jsp via iisproxy.dll

I have a jsp page being called by an IIS server. The jsp page comes up fine
          except for the images. I have a nav bar that is called via an include from
          the home.jsp page. I know the include is working. I see the code when I do a
          view source. I see the call for the images as well but they don't show up.
          Any ideas????. Do I have to have the images on the IIS server and the jsp
          pages on the Weblogic server?
          Thanks for any help


Correction. I meant....
          "Another way is to proxy by path/URL. Wait till next Service pack and you will have
          the ability to proxy by path. If you want a one off contact WebLogic Support.."

Iisproxy.dll & Permissions

The prescribed installation for the WebLogic-to-MS-IIS Bridge specifies
disabling the "Script engine" property in "Application Extension
Mapping" and the screen shot implies replacing the "Script" permission
with "Execute (including script)" at Home Directory. However, it is
possible to reverse those two settings with successful results.
It would seem to me this would be a preferable configuration from a
security standpoint. Is there any reason as to why this is not the
recommendation?
Thanks in advance.
Namaste,
Michael

I need to clarify that I want IIS to handle
          all traffic on port 80, and TomCat to handle
          all traffic on port 88.
          Basically, two seperate hhtp servers that
          should have nothing to do with each other.

WL vs WebSphere performance

I have been running informal benchmarks of WLS6.1SP2 and
WebSphere4.0.4 on a Win32 box, and am surprised to see WLS to come in
at ~60% of pagesPerSec/responseTime of WebSphere at same CPU
utilization. Has anybody exeperienced similar behavior? I have read
through the WL docs, but can't find anything in my setup that would
impose a performance penalty.
Using a Win32 2CPU box with 654MB RAM, WL setup: IIS using
iisproxy.dll proxies requests to two local WL servers. All tracing
(IIS and WL) turned off. Images served by IIS. Remote ORCL db,
connection pool size 10 initial/50 max. Same EJB used for both tests.

That's very surprising. WLS should outrun websphere.
Is the test environment idential? (ie does websphere go through the IIS
proxying as well?)
Are you using the same JDK for both setups? IBM's JDK tends to be
faster than the Sun 1.3.x that is bundled with WLS. You might also try
BEA's jrockit jvm.
How many concurrent threads are you running? If you vary the client
threads, does that change the WLS v Websphere relationship?
