IIS is free and included as part of the operating system.� If you're running on Windows XP, I believe it is called "Personal Web Sharing".� On Windows Server 2003, it may be an optional install.� As is the case with Apache, unless you need IIS for something other than Mid-Tier, I would not bother installing it at all.� Anything related to Mid-Tier is going to be handed off to ServletExec or Tomcat (depending on which you install) and that is where the real "work" happens.� In this specific scenario, introducing IIS just adds another unnecessary layer.
The only advantage I may see with using IIS on Windows is perhaps for ARS Mid-Tier sites which are very busy.� Since IIS is integrated into the operating system, I would like to assume that it has been very finely tuned to effectively manage a high number of socket connections.� In performance intensive situations, people tend to use either the Apache Portable Runtime with Tomcat or the Grizzly connector to manage socket-based communications.
If you decide to use Tomcat with IIS, you're going to need to install the ISAPI filter for Tomcat. 4) Should i DL tomcat or apache or both? And from what exact link should i DL for windows 32 bit version? Unless you need Apache for other features, I would just install Tomcat.� Much of my reasoning behind this can be found in the earlier discussion for using IIS.� Since Tomcat is 100% pure Java, there is no 32/64-bit choice.� Just download Tomcat 5.5.17 and install it. 5) Apart from tomcat or apache or both, what other S/w is needed? You will need to have the Java Development Kit installed.� I would install Sun's Java Standard Edition 5.0 Release 7 Development Kit (a.k.a., J2SE 1.5 release 7).� There are other options from other vendors, but this is the one I generally use.� I'd be curious to know how many on the list are using JRockit or the IBM JVM.� It's been a while since I've looked at benchmarks. 6) In what order should i install these products?
JDK� IIS or Apache (optional) Tomcat Mid-Tier
If you are going to use Tomcat alone, then when prompted to choose a web server, select the "Other" option.� Do the same for the question about the Servlet Engine.� I don't normally do this in LINUX/UNIX (I use symbolic links instead), but when you install Mid-Tier, install it to the <Tomcat_Installation>/webapps/arsys folder.� For example, if you install Tomcat to C:\Program Files\Apache Tomcat, then install Mid-Tier to C:\Program Files\Apache Tomcat\webapps\arsys.
Good luck with your install! � This is the first time i'm installing mid-tier, so pls help me out. � Jason

Subject: Re: MidTier on Linux

Derek,
I did pretty much the same thing, although I did not know about the Java Service Daemon so I am still running on Port 8080. When I install the Mid-tier, I just download the WAR file and pop it into the Tomcat webapps directory. I then stop and start Tomcat and it extracts the WAR file for me and installs the MidTier. After that, I copy the config.properties file over and I am good to go. I must say that Tomcat was very easy to install and config, I had some real problems with Apache/Tomcat on my AIX box.
I followed these instructions:
8. Download latest Midtier "war" file from Remedy Support
9. Rename war file to arsys.war and copy to tomcat webapps directory
# cp arsys.war /usr/local/jakarta-tomcat-5.0.28/webapps
10. Stop and restart Tomcat
/usr/local/jakarta-tomcat-5.0.28/bin/shutdown.sh
/usr/local/jakarta-tomcat-5.0.28/bin/startup.sh
11. Wait for arsys directory to appear under webapps (Tomcat will build)
# cd ../webapps
# ls -lrt
total 62688

12. Copy config.properties to /usr/local/jakarta-tomcat-5.0.28/webapps/arsys/WEB-INF/classes
Change the server references.
13. Test Midtier
http://<server>/arsys/shared/config/config.jsp
Mike.

Unless you have a compelling need to run Apache, have you considered just running Tomcat alone?� Most of the environments in which I deploy Mid-Tier, this is the configuration that we use because the web application servers are only being used for Mid-Tier.
The only out-of-the ordinary configuration changes that I've made is that I leverage the Java Service Daemon (JSVC) which ships with Tomcat (but you have to compile it) and allows Tomcat to bind to port 80, but run as a non-privileged user.� In addition, in the Tomcat startup scripts, I configure it to use the server-side JVM rather than the default client-side.
When installing Mid-Tier, I choose the "Other" options for both the Web Server and Servlet container.� And then I place an arsys �symbolic link in the /opt/tomcat/webapps�folder that points to /opt/ars-midtier (where I actually installed Mid-Tier).
If you are really concerned about performance, there are options available to you that can help address this such as using the Apache Portable Runtime (needs to be compiled) which is a native library that Tomcat uses via JNI to manage the connections at the TCP/IP level.� This is the same code that Apache uses for this purpose.� There is also the� Grizzly connector which ships with Sun's�GlassFish (open source J2EE server) is based on the Java Non-Blocking I/O (NIO) API which is a high-performance I/O API targeted for server-based applications designed to let applications handle more connections with fewer threads (ergo fewer resources).
I find this simpler because I only have to worry about configuring Tomcat rather than Tomcat and Apache.
Just a possible alternative.
Derek
P.S. My current production server environment consists of three hardware load-balanced x86 boxes running RHEL 3 Release 4, JDK 1.5 release 6, Apache Tomcat 5.5.12 and ARS Mid-Tier 6.3 Patch 14.� My development server is running RHEL 4 Release 2, with JDK 1.5 release 7, Tomcat 5.5.17, and Mid-Tier 7.0 Patch 1.

Greetings List,
�
System information for starters:
�
Database: MS SQL Server 2000 SP4 on Windows Server 2003
Application: Remedy 6.3 on Windows Server 2003
Web: MidTier 6.3 on Windows Server 2003 with IIS6 and Servlet Exec.
�
Now, onto the "problem".
�
I've gleemed from the list that the Win2K3/IIS6/MidTier/ServletExec combination is rather slow.� I've noticed some sluggishness myself.
�
I've also seen people mention that an Apache/Tomcat combination is quicker.
�
Therefore, I've stood up a Red Hat Enterprise Linux 4 Update 3 server with Apache and Tomcat.� Furthermore, I've installed MidTier 7 rather than 6.3 and pointed the install to the Application server listed above.
�
My questions are:
�
1.) Will MT7 work with ARS 6.3?
�
2.) Given that the above answer is "yes", what caveats do I need to know to get MT working correctly with Apache/Tomcat?
�
I know Apache is working as I can see the standard test page when accessing it from another box.� The same goes for Tomcat.
�
As far as installation is concerned, apache is at /etc/httpd and tomcat is (unfortunately at this time) is in a user's directory /home/<user>/apache-tomcat-<version>
�
MidTier is installed at /usr/ar/mid-tier.
�
These are all of the configuration settings I passed into the MT7 installer script, which finished without errors.
�
Any special configurations I need to make to MidTier, Apache, Tomcat, or all of the above?
�
When I attempt to access (from the RHEL box) http://localhost/arsys/config/config.jsp as annotated in the documentation, I get a page not found.�
�
I made a symbolic link in /var/www/http/ and pointed it to the MT install home directory and when I visit the page above, I see the JSP script in the browser window.
�
Thanks,//SIGNED//
