WWRUG attendees received a BMC draft white paper entitled "Fine-Tuning the Mid-Tier and the Web Infrastructure for Performance". Not only are there setting recommendations but a lot of good information about web apps, architecture and protocols in general. Right off when browsing it for the first time I realized that we had made some poor assumptions regarding TC settings in the past. Our first exposure to TC was also with MT and RKM and we are by no means TC experts. I did a quick check on the support site and was not able to find it. David Easter, do you know if this document is (or going to be) available on Support Central?

The reason I'm asking is one of my guys submitted a ticket to the BMC/Remedy help desk asking for one when he couldn't find it and was told one does not exist. I find it hard to believe there isn't something that explains how to create the linkage when these are installed separately for those of us who are novices with Tomcat.

The compatibility matrix lists the minimum version supported and customers are welcome to use any version at or higher than the minimum version. For example, AR System 7.6.03 supports Tomcat 5.5.28 or higher... it is not required that you use version 6.0.18. In the same way, 7.5.00 customers are welcome to use a later version of Tomcat if so desired. -David J. Easter Sr. Product Manager, Enterprise Service Management BMC Software, Inc.

We're not on 7.6 yet because the 7.6 midtier apparently doesn't support 7.0.1 database servers. We're trying to get the database servers all upgraded to 7.5 as well before moving to v7.6. Until then, we need a stable midtier. The bundled Tomcat version in 7.5 P6 appears to be v5.5.28. Are those settings you mentioned below applicable to 5x Tomcat? Willing to remove the threads setting if not recommended. If anyone knows why that's a bad thing--please respond.

Prior to this I have always installed the mid-tier using tomcat as the web server, not IIS. BTW, at some point during production with 7.1 BMC Support admitted to me that the 3000 threads settings they had documented in the past was an error, and should not be set at all. Eventually it dropped out of the mid-tier docs. Recently they told me that under Java Options: in the Apache Tomcat Tomcat6 Properties box, I should add the line: -XX:MaxPermSize=256m Apparently the mid-tier installer already adds the settings: -Xincgc -XX:PermSize=256m Adding this setting has cleared up some out of memory errors that I have seen when trying to load the RKM 7.6.03 console in mid-tier, among other things. These do not appear to be standard settings in a tomcat install - yesterday I built a midtier 7.6.03 on the 64-bit Windows distribution of tomcat 6.0.28 (trying to find a tomcat 6.0 build that will not only do SSL using a commercial certificate, but will work properly with mid-tier 7.6.03; the most current tomcat - 6.0.29 - had problems with mid-tier), and I had to add all three of the -X lines to the Java Options.

It appears to happen randomly and at no set memory limit. The last couple of times was in the 600-700MB in use when it happened. The service fails to stop or restart and has to be killed to get it started again. We're running the following: ARS 7.5 P6 Apache Tomcat 5.5.28 Java 1.6.0_21 Windows Server 2008/IIS7 Tomcat settings are 512MB initial, 1536MB maximum, and 3000 threads. We've always used ServletExec in the past. Those of you with a lot of Tomcat experience, what combination of versions/memory sizes have you found to be the most stable for ARS 7.5?
