RE: How can I get UserTransaction or TransactionManager
Thank you Heinz. I tried in other ways to manage a transaction, but I still have other problems about Orion TXN. What I wanted to do in my App. is as follows; Let's assume that user class and address class exist and their relationship is 1-to-1. 1. Create a user 2. Create an address object of the user if creating the address object is failed, I'd like to rollback creating a user. Trial 1 I used entity bean and session bean to manage the transaction as follows; 1. newUser method is one of the methods of a session bean, and the method's transaction attribute is set to RequiresNew 2. newAddress method is one of the methods of User entity bean, and the mehtod's transaction attribute is set to Supports 3. newUser method calls newAddress method. But, even though creating the address failed, creating a user was not rollbacked, i.e. new user was still in the database. Tiral 2 I used ejbContext to get UserTransaction in newUser method of a session bean as follows; ejbContext.getUserTransaction().begin(); create a user newAddress(); ejbContext.getUserTransaction().commit(); And set the session bean's TXN attribute to Bean but, the result was the same as above.

RE: communication among ejbs in different applications
Hi,Juan: Thank you for your suggestion. Do you think this kind of calls will violate any J2EE specs?

Slow RMI - returning 4000 empty wrapped Strings takes 9 seconds.
Hi there I've got a stateless session bean that returns an ArrayList of 4000 objects to a servlet. If the objects are of type String it takes a few milliseconds to return all 4000. If they are of a custom class (i.e. One I coded) that only contains a String object it takes 9 seconds to return all 4000. The stings are all close to empty in all cases (typically 5 characters). Something doesn't seem right. I'm running Orion from within Jbuilder for debugging purposes. I know that Orion automatically creates the client stub classes for EJB's. If these classes are not in my classpath I imagine Orion might have to fetch the stubs from the RMI server. If it did this 4000 times it might explain the slow-down. If this is the case where does Orion store the stub classes that it generates ? I want to add it to my class path. If this is not the case, does anyone have any idea what I might be doing incorrectly ? Thanks Henty
Problem with DataSourceUserManager on orion 1.5.2
I just upgraded to Orion 1.5.2 and my DataSourceUserManager stopped working. It can find the User info, but when the getGroup() call is returning null for some reason. Has something changed that would break this? (Also, I can't get to orionsupport.com or Orion's mailing list archive or I would have looked there first.)

SV: LDAP and EJBs
Title: SV: LDAP and EJBs
You would have one sessionbean being business delegate in front of the EntityBean manipulating the RDBMS and another managing the LDAP directory service. Then you would have a Facade in front of both these sessionbeans with one method that does the whole trick with transactional attributes set up to require a transaction before entering the method.
interface UpdatingFacade : SessionBean {
void doTheUpdate() throws RemoteException;
}
interface LdapDelegate : SessionBean {
void writeLdapEntry() throws RemoteException;
}
interface RdbmsDelegate : SessionBean or EntityBean {
void writeRdbmsRow() throws RemoteException;
}
Then you want an error in the writeLdapEntry() aswell as the writeRdbmsRow() to throw an EJBException breaking the transaction begun by doTheUpdate() method. Both writeXxx methods must require that a transaction already exists before being called. The doTheUpdate() method can really have it either way, as long as there is an active transaction associated to the thread calling it.

Patrik Andersson

Hi everyone!
I have a use case where I need to interface an LDAP directory and a
relational database within a same transaction. That is, to create a new
row to RDBMS from session bean using entity bean and to create an LDAP
entry from the same session bean using Sun's LDAP provider through JNDI.
1. Is this possible?
2. Can I use container managed transactions?
Thanks a lot!

RE: communication among ejbs in different applications
first, let's get one thing out of the way: 'parent' attribute is a JNDI facility, no more, no less. there still are separate containers for each app (this may not be useful in all apps, specially since transactions may not function as expected) it allows for JNDI properties to propagate BOTH ways (they always propagate from father to son, default father being the default-app) Now, this is where I was aiming to: have apps A, B deployed; do not use parent attribute. connect A B apps using JNDI parameterized contexts (see connecting from applet, application in www.orionsupport.com) Pray for correct transaction enroling/2PC.

We are setting up 2 cluster-islands witha load balancer running behind apache on same host (one physical sun box) for one web-application. So to add to my question above for 2 cluster-islands do we need to run 4 instances of orion or just 2 ? The documentation wasn't clear to me on this I have it working for a single instance of orion but need to do clustering for scalability and fault tolerance issues. How does this perform ?

RE: Cluster configuration
a resend... as far as stopping orion, the usual methods apply java -jar admin.jar ormi://localhost:the_rmi_port_number_for_the_instance_to_shutdown admin somepassword -shutdown force as for the loadbalancer, kill -s 9 pid seems to be the only thing that works. -Original Message- From: elephantwalker [mailto:[EMAIL PROTECTED]] Sent: Monday, July 09, 2001 6:21 PM To: Orion-Interest Subject: RE: Cluster configuration Its not the orion port, its the ormi, or rmi port that's complaining and the jms port that's complaining. If you set up more than one instance of orion on the same machine, you will need to change the jms and rmi port's in their respective config files so that there is no conflict. I think 23791 is the rmi port by default, and 9127 is the jms port by default. You can change these by changing the config/rmi.xml and config/jms.xml file settings.

I have a web-app that is shared. I am running Apache in front of Orion. I can start everything fine except for 2nd instance of orion in cluster i get the error: Error starting JMS-Server: Unable to bind socket: Address already in use Error starting RMI-Server: IO Error: Address already in use Warning: Error reading transaction-log file (/oracle/app/oracle/product/oas9i/Apache/j2ee_2/home/persistence/transactio n.state) for recovery: premature end of file Where can i change the ports for these or how would i resolve this ? Also i have apache running on port 80 and i would like to run loadbalancer on another port. Would i specify this port in the loadbalancer.xml file or at startup command line for loadbalancer ? Is it recommended to run loadbalancer on port 80 ?

So yes, you need at least 2 instances per cluster-island, and yes you install 2 separate orion instances with the same cluster id in the web-site.xml. I didn't run any benchmarks on my cluster setup, it was more just a proof-of-concept. Is there a reason you want 2 cluster-islands? because they won't share session information with eachother. Jeff.
