RE: [JBoss-user] httpsession clustering overhead
ECPERF is in CVS under the ecperf module. For testing with 3.0 series, you'll need to checkout: ecperf -r Branch_3_0 3.2 and higher, just check out ecperf regulary. It is configured to use either BMP, CMP, or clustering. You can email me for help, but I'm pretty busy right now so I may not respond to lengthy questions. Also ECPerf is not a good HTTP test. For that I suggest the RICE study (JBoss vs. Jonas). Dain has done some great work porting the test to 3.0, but we haven't committed it yet. Could anybody offer up machines for doing clustering benchmarks with RICE and ECPERF? I only have 3 machines at home and its just not enough. Email me if you're interested.

Random generators may give good uniqueness but that is not what they are designed for. java.util.Random is pseudo random and one should not expect good random behavior from it. java.security.SecureRandom is better quality but slow. I believe Tomcat can be configured to use either. SecureRandom is very slow, and Random is not really random, wouldn't rely on either for unique generation.

Re: [JBoss-user] is sessionid unique?
I'm working on user-behavior-tracking solution for a jboss application and I'd like to know how unique is sessionid generated by server (especially in long run, including server restart and aplication redeployment). After posting this I did some searching and found that in Tomcat sessionid is pure random (16 bytes written in hex) while in jetty it's just System.currentTimeMillis() based. Is Tomcat's sessid creation safe? 16 bytes is not small size but I guess nobody would accept such key generation for database... regards marcin --- This sf.net email is sponsored by: See the NEW Palm Tungsten T handheld.

Re: [JBoss-user] setting SecurityManager causes security exception in hybrid JBoss /RMI application
You need these permissions assigned to any code that interacts with the JBoss security
layer when running with a security manager:
java.lang.RuntimePermission("org.jboss.security.SecurityAssociation.getPrincipalInfo")
java.lang.RuntimePermission("org.jboss.security.SecurityAssociation.setPrincipalInfo")
java.lang.RuntimePermission("org.jboss.security.SecurityAssociation.setServer")
java.lang.RuntimePermission("org.jboss.security.SecurityAssociation.setRunAsRole")

Re: [JBoss-user] Running CMP2 tests: HSqlDB allows duplicate columns
Jonathan.O'[EMAIL PROTECTED] wrote: Folks, I'm on a mission to allow the same column be mapped to both a CMP field and a CMR field. What version are you targeting this for? Jboss 4.0 cmp is getting a complete rewrite that what will for one thing makes this type of n:m data mapping model trivial. Since 3.0 isn't really getting new features, this seems like a lot of work for just the 3.2 release. If you still decide to go ahead, be really careful with the cached values, as each field has a private cache and the last thing we want is an inconsistent cache. I made some mods to one of the tests (ReadOnlyUnitTestCase) and found that the create table SQL that JBoss generates contains a column name twice. Yes, fields are not allowed to be mapped to the same column. I have gotten patches that address the sql generation problem but none have address the big cache problem I mention above. That's fine, but hsqldb doesn't complain. However, Oracle hates such SQL. The version of hsqldb we use does no real verification of the query. Which DBs do the unit tests get run against? hsqldb, postgres and sometimes mysql... some of the other guys have tested on oracle Also, are all new releases supposed to run all unit tests cleanly? I'd like to see the test suite report added to release. They are supposed to, but don't. All releases should cleanly run the tests-db suite, which tests bmp, cmp 1.1 and cmp 2. -dain --- This sf.net email is sponsored by: See the NEW Palm Tungsten T handheld.

Directionally of relationships has no effect on the code; it is just a matter of convince for designers. With the performance patch you mention above, I make sure to not load relationships unless absolutely necessary for referential integrity, so what you are seeing is a bug. Please, file a bug report with a simple test case (Order-LineItem) that reproduces the error. -dain --- This sf.net email is sponsored by: See the NEW Palm Tungsten T handheld.

Re: [JBoss-user] httpsession clustering overhead
I did think of the backplane idea as well. But we also have memory consumption to think about. If I had four servers evenly balanced, say 100 users on each, I think I would end up with 400 sessions per server. Our sessions are currently pigs, and that is motivation to fix that! Perhaps better would be the cmp implementation which I haven't tried. There, it seems the servers could keep only the load they need, and if the get an unknown session, the cmp would pull in the data if needed. I'm not sure it really works that way though, I suppose it depends on how bean clustering works, and I haven't looked into that. It could be just as bad if bean clustering works in high availability mode as well! > Thats a good point that I once was worried about also.

[JBoss-user] httpsession clustering overhead
I am beginning to get httpclustering to work. Aside from the overhead of each server having to have the capacity to hold the total sessions in all servers, what's the wire traffic like? Yea, I'll sniff it if I have to, this is just to see if anyone has a quick idea. I'm guessing it sends out X bytes representing the serialized session data each time it is changed via setattribute, and all servers pick it up and store. Or is that not true? If so I suppose I have to ensure good granularity with the session data. Unfortunately we have a big ugly object that holds a lot of the info, which I can just imagine going out all the time for one or two field changes! I have my debug level of logging, and the logs don't tell much of what's happening. rick --- This sf.net email is sponsored by: See the NEW Palm Tungsten T handheld.

Re: [JBoss-user] Performance issue while adding to a EJB 2.0relation - JBoss version: 3.0.2
1. Do you run the code in a transaction? 2. Sun JDK 1.3.1_03 is AFAIK the slowest >=1.3 JDK you can find for linux. I recommend upgrading to 1.4.1 from sun, IBMs 1.3 or www.jrockit.com's 1.3. When you have done that, can you see any performance difference between Linux and Win2k? What kernel? Recompiled, or stock-RH-kernel?
