Claire did you ever get this resolved? I found that my OOTB Mid-tier 7.6.04 SP3, 64-bit, was also running very slow and memory consumption was really high. I am only running 10 gb of Ram on my servers. I got together with one of the company Tomcat Gurus and he suggested that I add a file called tcnative.dll and add it to the ...\ Tomcat6\Bin directory. It is a file that Tomcat uses to interact with Windows and is not shipped with BMC's Tomcat version. You can download it from:
http://www.apache.org/dist/tomcat/tomcat-connectors/native/1.1.24/binaries/tomcat-native-1.1.24-ocsp-win32-bin.zip and the 64bit dll is in the 32bit zip file and it has the open SSL dll with it. I didn't install the open SSL, but I did install the tcnative-1.dll and that helped a lot. I was actually able to resize the forms much easier. Also you need to set the permsize to 512 if you are getting low memory messages. I actually lowered my max memory pool to 2048 from over 3gb where I had it before and my Min memory pool is 512. Here are some more tips that he gave me to change in the web.xml file. It is supposed to help with performance by taking Tomcat out of Development Mode, which is what it ships with. It's as though its running in Dev Cache mode. <init-param> <param-name>development</param-name> <param-value>false</param-value> </init-param> <init-param> <param-name>reloading</param-name> <param-value>false</param-value> </init-param> So this <servlet> <servlet-name>default</servlet-name> <servlet-class>org.apache.catalina.servlets.DefaultServlet</servlet-class> <init-param> <param-name>debug</param-name> <param-value>0</param-value> </init-param> <init-param> <param-name>listings</param-name> <param-value>false</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> Should look like this <servlet> <servlet-name>default</servlet-name> <servlet-class>org.apache.catalina.servlets.DefaultServlet</servlet-class> <init-param> <param-name>debug</param-name> <param-value>0</param-value> </init-param> <init-param> <param-name>listings</param-name> <param-value>false</param-value> </init-param> <!-- add --> <init-param> <param-name>development</param-name> <param-value>false</param-value> </init-param> <init-param> <param-name>reloading</param-name> <param-value>false</param-value> </init-param> <!-- end of added --> <load-on-startup>1</load-on-startup> </servlet> After doing this my Tomcat's memory consumption is around 1 gb. Try it in your development environment and see what happens. Also try to make sure that your Max records on get list is set to under 10000 in Server information. I have it set to 10000 and that prevents users from running long queries which gobble up memory.

My network team says it is not the network. Even though it happens at almost the same time every day. I have no escalations running at that time and have done most of the tuning that was in the BMC documents. My tomcat service grows up to 5 GB fairly quickly. Of course when I restart the tomcat people stop reporting the slowness. Management wants me to submit a ticket to BMC (already done this several times) and there is no real result. They do a WebEx, look at the logs and there is no appreciable speed increase. The Mid-tier Server has 24 GB of ram. The Application Server has 16 GB. The Database Server has 16 GB ITSM 7.6.04 SP2 Mid-Tier SP3 ARS SP3 Oracle (latest version - can't find the patch number) The servers are all in the same physical location. The App and Mid-tier servers are Win 2008 and the DB server is a UNIX server. _______________________________________________________________________________ UNSUBSCRIBE or access ARSlist Archives at www.arslist.org attend wwrug12 www.wwrug12.com ARSList: "Where the Answers Are" Information contained in this email is subject to the disclaimer found by clicking on the following link: http://www.lyondellbasell.com/Footer/Disclaimer/ _______________________________________________________________________________ UNSUBSCRIBE or access ARSlist Archives at www.arslist.org attend wwrug12 www.wwrug12.com ARSList: "Where the Answers Are"
