Jboss 6.0 + PostgreSQL Datasource + security-domain + CallerIdentityLoginModule : Can i set max number of pools?
by Achilleas Mantzios
Hello and merry Xmas to all.
Being a jboss user (starting from 3.0.3, still deployed in some remote locations) for the the last 10 years
I have succesfully set up a new test system Jboss 6.0, postgresql 9.0.2, openjdk 1.6, in a porcess to completely
upgrade all of our application engine software.
I had an idea, instead of going the old way of creating the postgresql pool with one user (typically : postgres),
to try having personalized connections, which makes debugging, diagnosing a very very easy task.
So i set up <security-domain>postgresqluser</security-domain>, then in login-config.xml i defined
<application-policy name="postgresqluser">
<authentication>
<login-module code="org.jboss.resource.security.CallerIdentityLoginModule" flag="required">
<module-option name = "managedConnectionFactoryName">jboss.jca:service=XATxCM,name=pgsql</module-option>
</login-module>
</authentication>
</application-policy>
I set up both jboss and postgresql authenticate against the same LDAP server, and all the magic seemed to work!!
As i understand it, one separate pool will be created for each user.
However this is the only unpleasant thing in the whole story.
I'd like to have a way to restrict the max total pools created, in order to pose a limit in the max total connections to the db.
In other words emulate <max-pool-size> as if we were talking about the normal "OnePool" case.
Is there anything to pose a limit to the number of actual pools created?
This is not for use in high traffic web situation (where usually the apps are simple and the number of users large).
This is for a business, with 200 total users, but a big complexity of apps, queries, etc...
I am planning to set up min-pool-size=0, max-pool-size=4 and idle-timeout-minutes=5 minutes.
(maybe more fine tuning on this last one)
During the last 10 months, we had on average 100 distinct logged in users par day, and 130 max.
Haven't done yet any research on the definition/estimation of "cuncurrent" users in the system.
(in order to assess the max number of "simultaneous" connections).
Anyway, i'd like to ask :
a) if you see any potential risks with this
b) if there is a way to limit the max numbers of pools (as a means to limit the max total potential number of connections to the db)
c) My eye fell on http://docs.jboss.org/jbossas/6/JCA_Guide/en-US/html_single/#An_Overview_...
where it suggest that by specifying Criteria=ByNothing means
"all connections are equivalent, usually if adapter supports reauthentication "
Ideally what would be great is if we could have a total max number of connections, across all users,
and reauthenticating in the already existing connections.
I dont know whether postgresql supports this but it would be cool in general to have.
Thank you for any help!

by Kobi Biton

configurations on the JBOSS run.conf I am able to access via jconsole
IP:PORT , however I fail to see any JBOSS MBEAN , goggling and reading
it seems like the support of JCONSOLE And JMX on 4.0.2 is tricky can

[jBPM] - Problems with JBPM 3.1.7 login

Good day
I have installed JBPM 3.1.7 in JBOSS AS 5.01 and I'm having problems when trying to login.
It simply returns that the login is incorrect, but I have data loaded in the database, and the db configuration seems correct, since the Jboss AS log didn't complaint about it.
I am receiving this stack trace in Jboss Shell:

Since I don't know where is meant to be this user.properties file, I didn't create it.
I am using MySQL 5.5 and have configured the hibernate properties along with the database files.
If anybody can help me, I will be pleased.
Thanks to all.

My problem is "hanging" process after interacting with jBPM.
I start process (process with Human Task).
Everything works fine, process starts, human task is generating, but my app never end...
I think it "hangs" on CommandBasedWSHumanTaskHandler.
What am I doing wrong?

I succesfully deploy that process definition to JBPM, but it turn out that only task : task1, task2, task3 is assigned to the user. Other task (testing and task4) that should be done by group of user is not assigned.
What's probably missing or wrong in my process definition ?.
Thanks in advance for your help
