Any working MDB examples with 9.2.0.3? AQ? OJMS
Does anyone have a working MDB app for app server version 9.2.03 and database 9.2.0.1.0 ???
I realize the messagelogger app is not compatible; I also am having problems with the MDB sample from Wrox ch19.
In general, I am very confused about which JMS provider is supplied with this release and what is supposed to work with it. If anyone can give a clearer picture of oracle's JMS status, please do so. I have read the release notes and have just gotten more confused. OJMS vs. Oracle JMS vs. OC4J/JMS... what is what here. Also, how does Advanced Queueing (AQ) fit into the picture? Is it required with this release?
Thanks for any info on these questions.

Hi Stefan,
Exactly which Java component did the installation stop at, and if you go to the end of the install log (install log is in oraInventory/logs directory, it's named installActions<date>.log), what does it say?
If you forgot to set LD_ASSUME_KERNEL to "2.4.1", the installer will stop right at the beginning when it starts copying files. This is because although the installer is a Java app, it calls native shared libraries via JNI to perform OS operations like copying files or changing file permissions. Those shared libraries were compiled against an earlier version of glibc.
The only places where relinking stopped for me were at oemagent and at a ctx agent. The ctx agent has a fix which is well known. The oemagent cannot be fixed without hacking glibc source code and recompiling I think. I haven't had time to try that yet.
Cheers,
Dave

Error running A Simple MDB example with oc4j
Hi All,
I am new to OC4J, I am trying the example for MDB from OTN's site, A Simple MDB example with OC4J. When I start my OC4J on the command line > java -jar oc4j.jar

I have just followed all the steps provided to run the example exactly as given.

I don't know what is wrong. Please help me.
RohiniHello,
I guess that you didn't define the Topic and/or TopicConnectionFactory on your OC4J
Inside $J2EE_HOME/config (see: subfolders .../j2ee/home/config e.g.)folder are several xml files appropriate for OC4J configuration. There's also jms.xml. Please, verify this one, it should have some entries for your settings.
Just like in an example below:
<topic-connection-factory name="TopicConnectionFactory" location="jms/TopicConnectionFactory"/>
<topic name="theTopic" location="jms/theTopic"/>
The names should be the same like in your MDB deployment descriptors. It works of course after next OC4J server restart.
I hope helped you

Has anyone done any work in Labview with a Hund enviromental monitoring unit?
The data cable from the unit connects to a dongle that is plugged into the parallel port of the computer. The only software that work with dongle in place is the manufacturer's software, which is not adequate. I would like to create a VI using Labview to monitor the measurements taken by the unit.
Wow. You are in a tough spot. I could not find anything on our site that mentions Hund. Since the manufacturer is using a dongle, I would be surprised if they would reveal how to communicate with the instrument. If we had that information, we could do the communication in LabVIEW.
If the software program reveals some of its properties and methods using ActiveX, you can have LabVIEW use the software that controls the device. It is a long shot.

i need to add bpm to my songs but in some of them i just can't add/modify any info. it seems like it happens only with the verified songs (the ones i download from souncloud work for example) probably verified trough gracenote..is there anything i can do?
this is what happens when i try to add/modify the infos and it doesn't work, i'm even unable to click in the spaces
thanks for your attention,sorry for the bad englishRight-click on your main iTunes folder and click Properties, then go to the Security tab and click Advanced. If necessary grant your account and system full control to this folder, subfolders and files, then tick the option to replace permissions on child objects which will repair permissions throughout the library. This is the XP dialog but Windows 7 shouldn't be too different.

I'm using Sun MQ3.5 + OpenLdap2.2.20 as jndi remote binding mechanism.
I've unsuccessfuly tryed to add a Topic Factory!
Running the command

I get such an exception:

Thanks for any suggestion,
SilvanoAgreed.
I've been wanting to test the steps and write a tech article on this
and post it to somewhere on sunsolve.sun.com but have not had
time yet.
In any case, the instructions Ken-shi gave are below including
the 3 files (etang.ldif objectstore.properties slapd.conf). Not sure
how messy this posting can get due to size of files.
I'd much rather point you to a sunsolve article but don't want
to make you wait. When I do post the sunsolve article, this thread
will be updated with a ptr to it.
===Begin instructions===
Attached please see my working configuation files.
1.Modify your OpenLdap configuration. (see slapd.conf)
start OpenLdap: ./slapd
2.Modify you initial data.( see etang.ldif)
load initial data: ldapadd -x -D "cn=Manager,dc=etang,dc=com" -W -f
etang.ldif
3.ObjectStore properties ( see objectstore.properties )
create your object store with "Administration" GUI on windows;
while creating destinations or connection factories, be sure that the
lookup names start with "cn=".

I just bought a new MacBook Pro this summer and was all excited. But I'm very frustrated right now because I can't connect to any external monitors through VGA. My thunderbolt (DisplayPort Mini) to HDMI works just fine, but when I try with my other connector to go from Thunderbolt (DisplayPort Mini) to VGA, Nothing works. my screen goes blue and changes size like it recognized something but nothing is ever detected on the external moniter or projector. I'm not sure what is wrong but it's very frustrating. I'm just very depressed that it worked just fine with my 2-year-old MacBook Pro but isn't working now. I'm running OS X 10.8.2. I just upgraded yesterday from 10.8.1 but that upgrade did nothing to fix my problem. Can anyone help? Thanks
I am haveing this exact same issue. I have plugging in 3 monitors and tried two different VGA to mini displayport and nothing is working. I recently bought a Acer monitor and it work for an hour and now it back to doing the same thing.
When I plug the VGA adapter in to the monitor the monitor think its not connected to a computer then when disconnecting the VGA adapter the monitor thinks it is connected to a computer.
NEED SOME HELP!!! at the point of all my hair is pulled out.

that is the same problem i am having! if anyone can help that would be great i'm losing my mind over here -

Hi i been try to minimise few app like safari,Ical etc etc from the fullscreen view but didn't manage to find any solution!! With the command M shortcuts didn't work...any help???
To make a screen full screen, you click on the arrows in the upper right corner. To minimize, move your cursor all the way to the upper right corner of your desktop--give it a second--a symbol will appear that lets you "reverse" the action and minimize the window. Hope I'm explaining this correctly.

Lots of existing threads, but no consistent answer - what settings need to be applied to the 2012 (new) Airport Express for it to work at hotels with an ethernet only connection? Any answers specific to Japan would be helpful. I would prefer not to take my old Dell laptop and just be able to use my Ipad 2 via the wireless connection that the Airport Express creates. However, I can configure the Airport Express at home prior to leaving if that is the best thing to do.
I have a very similar problem with my AE! My MacBook, MacBook Pro & iPod Touch (1st Generation) all get a GREAT signal from our AE. BUT, our iPod Touch (2nd Generation) and new iPad (WiFi) get terrible signal strength unless we're right next to the AE!! Tech support at Apple is of no help! I'm ready to sell them all! This all started when we got the last OS update for iPod Touch/iPhone/iPad. So it must be a software issue not a hardware one..
Any ideas?
