--UTL_SMTP.VRFY (vs_conn,'[email protected]') ;
can u anyone help

The VRFY command is basically useless.. had a good intent, but no practical way to do it accurately and correctly, nor does it serve any real purpose.
Some servers (especially older SMTP version) will simply parse the e-mail address and check if the format is correct. E.g.
-> VRFY [email protected]
<- 252 <[email protected]>
Newer servers will return a 502, meaning that the command is not implemented. E.g.
-> VRFY [email protected]
<- 502 smtp.domain.com: Command not implemente
The reason for this is that in the vast majority of times, the SMTP server you are talking to does not own the address of the recipient. You usually send e-mail to someone in another domain, via your domain's SMTP server.
How can your domain's SMTP server verify the recipient's address when it belongs to another domain? And what can it check? The domain name? How and why? It is not as simple as it sound.
When you deliver an e-mail to recipient on the same domain, the VRFY also does not make sense. Why waste a round trip on that command? If VRFY says okay, you still need to send the address via the RCPT TO command. So simply send a RCPT TO command and have the server telling you yea or nae - a single round trip dealing with the recipient's address.

Can I use short commands in CCNA exam

Can I use short commands in CCNA exam
for example
“conf t” instead of “configure terminal”

Sim questions are always answered by configuring
something!
The Exam Engine grades the running config, not the
startup config
Before exam day …
Practice as much as you can (real gear, simulators, sample
tests, read every configuration in books, repeat labs while in
class, etc.)
Use multiple sources for practice/review of configurations
Exam day …
Do what you can—partial credit!!!
Start with “show running-config”
There are no style points!
You can use the short version of commands on the exam.

How can I use a 3rd party XML parser such as xerces with OC4J ?

Hi all tech experts,
I am using Oracle Application Server 10g Release 2 (10.1.2) and i have
installed Portal and Wireless and OracleAS Infrastructure on the same
computer.
i tried all the solutions on this thread
Use of Xerces Parser in out application with Oracle App Server 9.0.4
but still fighting.
I have also posted this query on OTN on following thread
How can I use a 3rd party XML parser such as xerces with OC4J?
but no reply....
Please help me on this issue.
Since OC4J is preconfigured to use the Oracle XML parser which is xmlparserv2.jar.
i have read the following article which states that
OC4J is preconfigured to use the Oracle XML parser. The Oracle XML parser is fully JAXP 1.1 compatible and will serve the needs of applications which require JAXP functionality. This approach does not require the download, installation, and configuration of additional XML parsers.
The Oracle XML parser (xmlparserv2.jar) is configured to load as a system level library of OC4J through it's inclusion as an entry in the Class-Path entry of the oc4j.jar Manifest.mf file. This results in the Oracle XML parser being used for all common deployment and packaging situations. You are not permitted to modify the Manifest.mf file of oc4j.jar.
It must be noted that configuring OC4J to run with any additional XML parser or JDBC library is not a supported configuration. We do know customers who have managed to successfully replace the system level XML parser and the Oracle JDBC drivers that ship with the product, but we do not support this type of configuration due to the possibility of unexpected system behavior and system errors that might occur from replacing the tested and certified libraries.
If you absolutely must use an additional XML parser such as xerces, then you have to start OC4J such that the xerces.jar file is loaded at a level above the OC4J system classpath. This can be accomplished using the -Xbootclasspath flag of the JRE.
i have also run the following command
java -Xbootclasspath/a:d:\xerces\xerces.jar -jar oc4j.jar
but no success.
How could i utilize my jar's like xerces.jar and xalan.jar for parsing instead of OC4J in-built parser ?
All reply will be highly appreciated.
Thnx in advance to all.

Hi Neeraj Sidhaye,
I am trying to deploy a sample xform application to the Oracle Application Server (10.1.3). However, I encountered the class loader issue that is similar to your stuation. I tried all the three solutions but the application is still use the Oracle xml paser class. I am wondering if you have any insight about this?
Thanks for your help.

Can I use more than one bluetooth device at a time with my iphone4

Can I use more than one bluetooth device at a time with my iphone4

Anthony
I have a Plantronics 975 earpiece that works very well with my Razr. I
just got a Panasonic KX-TG7873S phone system for my home, it has a
"Link-to-Cell" cellular convergence solution, from what I understand it is
just Bluetooth enabled. I have paired both device with my Razr. In
settings, Bluetooth setting, both device show. But only one device can
connect at a time. If my Plantronics is connected and I choose the
Panasonic device, the Plantronics device disconnects and the Panasonic
device then says it is connected. Both devices work when they
are connected. Is it because they are both "headsets"?
So, to have to remember to connect to one or the other device, depending on
weather I am coming or going is not practical.

Can I use Logic Pro 9.1.6 on two computers with one licens

I have download and install Logic Pro 9.1.6 on my MacBookPro 13". I record on location with my MacBook an wil edit and arrange the music on my iMac at home. Can I use Logic Pro 9.1.6 on two computers with one licens. I'm the owner of both computers. If it can where can I find the program on my MacBook? and how to install and register?

Hi, is the iMac also 10.6.8? I had an iMac die when 10.6.8 was installed, it worked at first but after some You Tube flash videos the screen just locked and no mouse clicking anywhere did anything. It turned out that most older iMacs [ mine was from august 2007] have a graghics chipset that can't handle Snow Leopard, there were [are?] 77 pages on this "locked screen"topic in the Snow Leopard forum. I checked out a web site that tells you how much your mac is worth by filling in the sereal number-mine was worth only $168, I may give it to a friend for his children to play with, although that seems unholy. I doubt anyone woud buy it,the problem is now so well known that even Apple certified resellars here in the Netherlands refuse to repair them,they claim Apple will revoke their certification if they replace the faulty Graphics unit,it is also VERY hard to get to that unit in an iMac, everything is so tightly packed inside.
If your iMac is running Mountain Lion[10.8.0] you may have to change the app store preference to accept apps from all sites,normally ML will only allow app store apps to be downloaded.

How can I use a firewire hard drive on a new Macbook with one USB-C only?

How can I use a firewire hard drive on a new MacBook with only one USB-C?

kaz-k is correct about FireWire not being supported by any possible connector or adaptor to USB-C and never will. However, there is no such thing as a FireWire Hard Drive. There are only SATA (or if it is a really old one, ATA,) drives in a FireWire enclosure. If you can remove the drive from the case/enclosure - bust it open somehow if it is a glued-up unit - then the drive can be placed into a regular USB3 enclosure. Then it can connect to the new MacBook via any one of the adaptors Apple sells.

How come you can not use more than 126GB of a 1.5TB diskdrive with LabVIEW Real Time?

How come you can not use more than 126GB of a 1.5TB diskdrive with LabVIEW Real Time?
This is only 8.3% of the available disk drive space!
http://digital.ni.com/public.nsf/allkb/E7E2F5657B6026358625750B007201A6?OpenDocument
National Instrument's solution is either reformat you drive to less than 126GB or replace the drive with one less than that size.
Please NI, tell me you are going to fix your LabVIEW Real Time soon, and that we won't have to wait for LabVIEW RT 9.2.1 in 2011 for this one to be fixed.
http://upload.wikimedia.org/wikipedia/commons/9/90/Hard_drive_capacity_over_time.svg
Drives as large as 126GB or more have been around since about mid 2002. That's about 7 Years now and LabVIEW Real Time STILL can't use drives larger that 126GB! Please NI. Do something.
We deserve fixes to the old versions of LabVIEW RT. How about updates to LabVIEW RT. Such as 7.0.2, 7.1.2, 7.6.2, 8.0.2, 8.2.2, 8.6.2.
We don't need new features or versions of LabVIEW RT such as 9.0 until we have some of bugs fixed in the existing versions.

The RealTime OS is an NI Product that is purchased from NI.
NI may or may not outsource design, developement, or manufacturing of the products that it sells under its own Company name.
For this reason I would be concerned if I were a PXI Embedded Controller designer/developer in the United States.
Yes, 126GB is some space. I see that there are now 2TB drives available. 126GB would be 6.3% of a new 2TB drive. Should we all be happy with being able to use 6.3% of the available drive space. Moore's Law seams to be alive and well. Drives larger than 126GB have been readily available for 5 or 6 Years. This should not be a surprise to NI. Why don't they do something about it.
Thanks for the trivia on Bill Gates. I must have missed that one since I don't try to keep up with Microsoft. I believe that he is a wonderful person and he and his family are doing wonders for the world in their "retirement". The world needs more like him.
What I do remember is Steve Jobs telling us that we would never need more that 128MB and that we would never to need to do anymore software development because everything was already in the "ToolBox".

How can I use JTA in my business logic and execute process with PAPI?

HI All,
How can I use JTA in my business logic and execute process with PAPI?
When my business logic has exception, the process will rollback.
or the process has some exceptions, my business logic also will rollback.
I don't know how to do it.
Does anyone know how to do it?

Thank you for your reply, Daniel.
But I think I did not express my mind clearly.
There is a scene that I have 2 Application Server.
My business code is deployed in one Server.
The BPM is deployed in another Server.
I want to execute Task use PAPI.(ProcessServiceSession.runActivity)
In my business code, I will do something before execute Task.
I need my business logic and Task in same transaction.
To ensure them "all-or-nothing" .
As you say, if The transactions are managed by Oracle BPM.
then can I retrieve OBPM transcaction in my business code?

The one needs 7.4 (or better), the other 8.1, so Photoshop CS5 with ACR6 is not up to the task.
The free DNG Converter could be used to convert the RAW images to DNG which your version of ACR should be able to process.
