Sure, Jiri. It is in BMC's own documentation, a white paper called Performance Tuning for BSM. You can find it in the AR System 7.6 documentation.

BMC states that the 32 bit jvm is about 45% faster than the 64 bit. Your choice, just want to be sure you see the cost from both sides. > > Rick > On Jun 29, 2011 8:29 AM, "Wilson, Jeffrey M" <[email protected]<mailto: [email protected]>> wrote: >> Hi, >> >> We're running into some issues with a midtier upgrade that we're are trying to implement.

For example, a user can click on the View button on Task tab of the Incident form but nothing happens on the 7.6 midtier. There are no errors generated in the tomcat or midtier logs. At this point, we're not sure if there is a common thread between the missing active links. I realize that BMC has documented that there are certain expected interoperability issues associated with a 7.6.0.4 64-bit midtier and older AR server versions but the documentation indicates the limitations are related to data visualization fields. We've already tried using a 32-bit JVM but that had no impact on the active link behavior and defeats one of the purposes of the upgrade (more java heap space). I'll try installing 7.6.0.4 SP1 this morning. Has anybody run into this before with a hybrid configuration? Are there any obscure midtier configuration changes that are necessary that might have been overlooked? Any suggestions on other things to try? Any help that you can provide would be appreciated. >> >> Thanks, >> Jeff >> >> >> >> _______________________________________________________________________________ >> UNSUBSCRIBE or access ARSlist Archives at www.arslist.org< http://www.arslist.org> >> attend wwrug11 www.wwrug.com<http://www.wwrug.com> ARSList: "Where the Answers Are" > _attend WWRUG11 www.wwrug.com ARSlist: "Where the Answers Are"_ > > ************************************************************************************************* > > This email is intended for the named recipient(s) only.
