Hey all... Im looking for study material for the oracle 9i 1z0-147 exam. Basically Im looking more for reading material rather than questions. Study guides or tutorials. If anyone could point me in the right direction It would be appreciated. Haven't found a lot myself. Most stuff online refers to studying for 1z0-101 to prepare for 1z0-147
Thanks all

Thanks for the pick me up Kathy. It's good to know there is someone like you so involved helping us greenhorns out. Like I said your site is a phenomenal resource and it's so super that you would even take the time to respond. You rock

Unfortunately it was with an embarassing (for me at least) 72%. Scored well in the 90's for my other 3 certifications. But I guess I booked a little early on this one and I didn't sleep last night. Should have studied the material more as well. Especially container managed persistence and relationships.
I bought whizlabs and softscbcd. Never really used whizlabs though. I found softscbcd better for a run at tests. It's simpler but tests the topics very well. Whizlabs has more in depth, ridiculously so at times I thought. But if I had more time I would have used it. If you can do their exams then you have no worries. Thx to Kathy and Bert for their book and this site. This site is probably one of the best educational resources I've found online.
Anyway off to do IBM UML or XML or OCA Developer. Guess we'll see which topic is more interesting. Bye all!

Im using softSCBCD simulator to study... and I ran across this question
A message-driven bean ProcessOrderBean with container-managed transaction demarcation has the 'Required' transaction attribute specified for its onMessage(javax.jms.Message) method.
If the invocation of onMessage method on ProcessOrderBean instance always results in transition of the bean instance to 'does not exist' state, then which of the following methods might have been invoked from onMessage(javax.jms.Message) method (select the best answer):
A.javax.ejb.EJBContext's setRollbackOnly()
B.javax.ejb.EJBContext's getCallerIdentity()
C.javax.ejb.EJBContext's getRollbackOnly()
D.javax.ejb.MessageDrivenBean's ejbRemove()
Now I chose D ... their answer is B. I see what they are trying to say. Their argument has to do with B causing a system exception resulting in Does not Exist. My question's are,
1.Is there even a getCallerIdentity function in EJBContext? (I didn't see it on the Interface summary at the back of the HF: EJB book, saw getCallerPrincipal but that's not what they wrote, infact they say getCallerPrincipal is another way as well as getEJBLocalHome() and getEJBHome() to throw a system exception.)
2.Wont ejbRemove in javax.ejb.MessageDrivenBean result in a transition from ready to Does Not Exist. Their question mentions nothing about exceptions so I assume D is a better answer than B.
Does it have something to do with the fact that 'invocation of onMessage method on ProcessOrderBean instance always results in transition of the bean instance to 'does not exist' state' is that akin to saying they're throwing a system level exception? As opposed to the container running ejbRemove. Hmmm I may have just answered my own question in writing this post... But I put so much work into it I'll post it anyway just to get some feedback :roll: Thx all

Can a stateful session bean instance can be passivated while it is associated with a transaction?
