FYI, we have been running with the settings Tauf listed below for quite some time (2, 5a, and 5b). Our memory is -Xms512m and -Xmx 1024m, but we are on a 64-bit Win2K3 server with 12 gb RAM so the only limitation is the 32-bit Java.
Our ChunkSize=100, but our OutgoingConnectionRecycleSize=500 Polling Interval in the configuration form is 5 minutes. These settings have been scrutinized by support MANY times since we have been working on an issue with the 7.1.00.002 and 004 email engine dying silently since June 2008. Sometimes it dies on a failure to parse incoming mail, but frequently it is just a silent death where the service is hung. The latest armapi71.dll we are using appears to have solved the parsing problem, but the jury is still out on long-term stability (the latest is the dll in patch 7.1.00.006). I have not been seeing a backlog of messages (except when it hangs), but we normally have only 1000 to 2000 outgoing messages on a work day.

The following will show you how to increase the # of threads used to 4. You can try the following (assuming windows here): 1. Open up the registry and go to: HKEY_LOCAL_MACHINE>SYSTEM>CurrentControlSet>Services>BMC Remedy Email Engine>Parameters 2. Edit the JVM Option Count. Should be set to 2. Change it to 4. 3. Create a new String. Value name should be JVM Option Number 2 Value data should be -Xms128m 4. Create another new String. Value name should be JVM Option Number 3 Value data should be -Xmx512m 5. Now in the emaildaemon.properties file, use these params: a. com.bmc.arsys.emaildaemon.NumberOfSenderThreads=4 b. com.bmc.arsys.emaildaemon.FetchUserGroupInfoOnDemand=true Hope this helps your performance woes. It helped me a great deal. Tauf Chowdhury Analyst, Service Management Office: 631.858.7765 Mobile:646.483.2779 From: Action Request System discussion list(ARSList) [mailto:arsl...@arslist.org] On Behalf Of Pasterski, t...@dts Sent: Tuesday, March 24, 2009 5:23 PM To: arslist@ARSLIST.ORG Subject: Email Restriction - ARS 7.1 Patch 005 ** In the emaildaemon.properties (7.1 P5) there is a parm: <com.bmc.arsys.emaildaemon.ChunkSize=100> which restricts the number of messages sent with each poll to 100. I suppose that normally that is adequate if you poll every minute but during heavy message traffic even then it can cause significant delays. You cannot increase the parm or the email engine will fail to start. Support suggested adding parms: com.bmc.arsys.emaildaemon.NumberOfSenderThreads=1 com.bmc.arsys.emaildaemon.OutgoingConnectionRecycleSize=200 But for what I don't know, didn't change a thing. I tried to remove the ChunkSize parm and raise the RecycleSize and no change also. 100 is just inadequate, we have 9000 in the queue now! Anyone else experience this / have a solution?
