Have you tried setting your plugin logs to fine? What java are you using? 32 bit? 64 bit? Are you mixing between the two? Meaning 32 bit for some components and 64 for others? If so eliminate that if possible and use either 32 or 64 across the board..

Also, when I submit a service request, it’s not creating the incident. I ran filter/api/sql logging to no avail. I was getting an error stating Unable to connect to Ar System Plugin Server when I tried submitting an incident (after marking yes to the option in Rules that creates request on submit). A filter (don’t have the name right now) like SRM USM… failed and it looked like it was doing a run process as well. It may not be related to load balancing at all and a plugin configuration error but I am lost right now… Tauf Chowdhury | Forest Laboratories, Inc.

I have seen plugin errors with 7.6.03 that seem to be resolved in 7.6.04 that are not related to load balancing but I suspect is related to the fact that 7.6.03 was not yet supporting 64 bit java at all points wherever Java was required.. On 7.6.03 for eg, if you used 64 bit java wherever 64 bit is supported and 32 wherever 64 bit was not (which is exactly what I had done) I was unable to set the Server Ports and Queues using the plugin interface. Changing values there would not result in any errors, not even in the plugin logs when set to fine, but it just wouldn’t change the configuration. Close that administration form and reopen it and those values would read the current values (unchanged) from the config file, and your new values would not be seen. Even from the timestamp on the ar.conf file it was clear that it was not even touching the file.. Remedy support had recognized it as a bug.. It was resolved when I used 64 bit java all round in 7.6.04 where areas where 64 bit java was not supported was then supported.. Which is why I get that feeling it was because java versions were mixed and matched in 7.6.03, it may have created that problem.. What is the nature of your problem?

Two load balancers, one in front of the web, another between web and app. The only issues we are experiencing are related to session timeout problems, which is server clustering related…still working on that one. If you are getting plugin errors, ensure that in your armonitor.cfg file you are starting your java plugin server connecting to your individual node alias, and in the ar.cfg file, ensure that all of your java plugins are connecting to the same node based name… If you are by chance using Tomcat for your clustering, I would be willing to accept config tips/files to help smooth my road J From: Action Request System discussion list(ARSList) [mailto:arslist@ARSLIST.ORG] On Behalf Of Chowdhury, Tauf Sent: Friday, April 22, 2011 9:31 AM To: arslist@ARSLIST.ORG Subject: 7.6.04 - Load balancing ** Has anyone set up Remedy 7.6.04 as a server group with a hardware load balancer in between the mid tier and AR servers? Has that gone well? We set the “enable lifespan” option on the mid tiers and had the load balancer clear the persistency flag and are seeing odd plugin errors. Not sure if it’s related. I have a ticket open with BMC but curious if anyone experienced the issue. Tauf Chowdhury | Forest Laboratories, Inc.
