bye,

Look at this URL:
http://www.vamphq.com/jwsfaq.html#offline
It describes two methods, one dumb method, used by Java Webstart and JNLP-Services, but the second method could be usable for you, it tries to resolve a Internethost within a given timeout.

Hi Gurprit,
A null value is being passed at runtime. Make sure that you enter values when filling in the form.
Also check for the cardinality of the nodes being used. You can also initiliaze your value attributes as follows:
In wdDoInit() method:
wdContext.currentNodeAElement.setValueA("");
Context is as follows:
RootNode
|____NodeA
        |_____ValueA
Hope it helps.

How to implement XI interfaces in online and offline modes?

Hi Everybody,
Can you please tell me how to implement XI interfaces in online and offline modes?
thanks a lot,
Ramya Shenoy.

Hi,
Are you looking for Push and Pull mechanism of PI?
When the adapters like SOAP, HTTP, IDOC, etc. send the data to PI , it is nothing but a push mechanism, and hence the communication is synchronous by default.
But adapters like JDBC, File, etc. they fetch the data from Source Applications, so it is a kind of Pull mechanism for PI, and
by default communication is asynchrnous.
Pls elaborate exactly what are you looking for?
Regards,
Supriya.

Wut mean by online and offline option in OBIEE Administration?

Hello Dears ,
any one cane told the difference of online and offline option to open a repository in oracle BI Administration?
Regards
shakeel khan

OBIEE Administration can be done in two modes
1) Offline
2) Online
Offline: Where most of the developement work is done and repository is not loaded in to the server
Online: Repository is loaded in to server and few modifications are done.
When the services are started( Bi Server and Presentation Server) the repository is loaded in to the server and when try to open the repository in Offline mode it open in Read only mode.

Accessing BI system online...

Hi,
I want access SAP BW/BI training/IDES system online. Is there any way?
Are there any free downlaods available for this?
Thanks in advance.
Thanks...

HI Anuj
As of now we have only the executable file avalable online. But after intalling that too you need to connect to the server. And this server details need to be cofigured through VPN only..
Or the other option is to get the software purchased it online.
Thanks & Regards

AE 12.2 - online or offline updates?

Just updated adobe applications, not sure after effects was even one of them but hey, and my workspaces have disappeared.
Ae says it's version 12.2.1.5
I'm aware they're about to update, but I'm not keen on downloading that until bug roll outs come into force.
C:\Users\ME\AppData\Roaming\Adobe\After Effects\12.2\ModifiedWorkspaces
I have two modified workspaces in here, xml files, yet in AE I only have the standard options, with new, delete and reset at the bottom.
Is this to do with sync settings and being online or offline? What do I need to do to get these back.. I'm sure those two workspaces are what I need, they just aren't loaded in at all?
I have re opened a few times.
Thanks all.

Any one have any hints on this?
I can see where my account is connected to now but don't know where it would have been kept or connected to before..
I just find this a bit confusing. Any light on this would be great.

Itunes won't play on computer when online only offline

I have 2 computers- I downloaded the Itunes program on both of them yesterday. On computer A I purchased 2 songs and played them yesterday without problems (online and offline). I copied them onto a flash drive and moved them onto comptuer B and it played fine. This morning while using computer A & connected online, my newly purchased Itune songs would not play (completely skipped the songs- although they were checked). I was logged on to Itunes and the computer was authorized (I was also logged off on computer B). As for being authorized it said I was successful in authorizing 2 computers out of 5 that I'm allowed. So I recently got off line and and the songs play just fine. Why? And how can I correct this?

Hi,
Delete track and go into iTunes Store>purchased (under quicklinks) and redownload track.

How recognize if you are working online or offline

How an application programmatically find if it is working online
(you started from the browser so you have a connection for sure)
or if you are working offline(started from the local webstart center)?
best regards
AT

There is no way to really tell if you are online of offline. you can try the api: BasicService.isOffline(),
but this will allways return false unless you set the Application Manager to offline mode, and then
launch the app from there. Then it will run javaws -offline ... which will return true from isOffline().

HT2513 it ask to go online or offline and keeps on asking

You cannot lock or find the device until it comes online. You can schedule a lock sequence to be sent once the device is online. That's it. Furthermore, if whoever finds the device completely erases it, then even when it comes online you will not be able to track it.
What To Do If Your iDevice Is Lost Or Stolen
If you activated Find My Phone before it was lost or stolen, you can track it only if Wi-Fi is enabled on the device. What you cannot do is track your device using a serial number or other identifying number. You cannot expect Apple or anyone else to find your device for you. You cannot recover your loss unless you insure your device for such loss. It is not covered by your warranty.
If your iPhone, iPod, iPod Touch, or iPad is lost or stolen what do you do? There are things you should have done in advance - before you lost it or it was stolen - and some things to do after the fact. Here are some suggestions:
This link, Re: Help! I misplaced / lost my iPhone 5 today morning in delta Chelsea hotel downtown an I am not able to track it. Please help!, has some good advice regarding your options when your iDevice is lost or stolen.

Online or Offline status

I love the way the Adobe Forum is structured where you can
see if a user is online or offline. I wish to produce the same
method. I have a list of users in my admin page where I see the...
Username | First Name | Last Name | E-mail
I wish to make a fifth column called status that would have
online or offline such as...
Username | First Name | Last Name | E-mail | Status |
MySQL statement looks as such...
CREATE TABLE `adminusers` (
`userID` int(11) NOT NULL auto_increment,
`userName` varchar(50) NOT NULL default '',
`userPassword` varchar(50) NOT NULL default '',
`emailAddress` varchar(50) NOT NULL default '',
`firstName` varchar(50) NOT NULL default '',
`lastName` varchar(50) NOT NULL default '',
`date` timestamp NOT NULL default CURRENT_TIMESTAMP,
`userTypeID` int(11) NOT NULL default '3',
PRIMARY KEY (`userID`)
) ENGINE=MyISAM DEFAULT CHARSET=utf8 AUTO_INCREMENT=1 ;
I believe that the online/offiline status is a boolean
statement but I am not sure and do not know how to incorporate it.
Can someone help me what I must do. Thank you all for your
help.

There is no way that you can tell whether someone is online.
The web is
stateless. All that Adobe is doing is taking an arbitrary
time since
that individual either logged in or last clicked a link. It's
done by
updating a timestamp each time the visitor clicks a link.
Online or
offline status is determined by the time elapsed since the
last activity
(usually 5 or 10 minutes).

Why did i spend $479 on a DVR security system online

why did i spend $479 on a DVR security system online? i never bought on bestbuy.com before and will not again i wanted geek squad protection when i went to pick it up they would not give it to me. the geek protection is why i buy at best buy. they said it was because of vandalism well i will be taking it back on Sunday or Monday and going to Sams club where i can get a extended warranty. i called the 1-888-best buy number THE CUSTOMER CARE LINE and the lady ask me did i receive it and i said yes she than said it was up too the store if i could get it. well i asked for the protection before i took possession well no more best buy for the man!

Hello confer669,
I appreciate you bringing us your business and for coming to us with this inquiry! I can understand your desire for Geek Squad Protection (GSP), as I get it on almost everything I buy from Best Buy. That is as good of a reason as any to come to us for your technology purchases. I am very sorry you were unable to receive that on this product.
We offer GSP for the majority of our products; however, not every type of product has the option for GSP. In this case, it wouldn’t have mattered asking the associate for the protection plan before completing the pickup or after. When looking at the product info page for an item on BestBuy.com, if it has a GSP plan available for it, you should see a “Protection & Services” tab showing you the available plans associated with that product. Also, when you click the “Add to Cart” button, a pop-up window should appear displaying the available GSP plans as well.
Please let me know if you have any additional questions or concerns.
Respectfully,
JD|Social Media Specialist | Best Buy® Corporate

You cannot. Your best course of action is to immediately change all your internet passwords, notify the police and your insurance company. Send the remote wipe command to the MBA through iCloud.com and buy a new one from the insurance reimbursement.

Making data in tables online and offline - Backup/Recovery for tables.

Hi All,
I'm working on a project where the functionality is similar to 'Backup and Recovery' for database tables.
Lets say we have a set of 6 tables T1, T2.... T6. They do have relationship between them. The tables in questions are simple standard tables, which are not table partitioned.
- I want remove the records from live tables based on user entered date ranges and store it in some offline medium.
- I might want make the data online again from the offline medium; Application should be able use that data without any modifications.
- Different offline mediums can be
a) Flat file
b) Different table space
c) Any other secondary medium (like XML, tape..Etc,)
The total number of records will run in millions.
The proposed solution should consider,
1. Performance - Java solutions not feasible. Anything in SQL, PL/SQL or runs in DB itself(tools) are OK.
2. Reliability - Should be highly reliable, Data corruption simply unacceptable.
3. Security - Users should not be able to make out of the file.
Few options include:
1. Use partition
2. Use SQL*Loader
3. Export and import of tables.
My main targets:
1. Reduce space.
2. Increase performance for queries.
Please pass on your suggestions, any help is highly appreciated!
Thanks In Advance!

If you truely need to get the data out of the Oracle database into flat files, partitioning is pretty useless. Partitioning the table, though, strikes me as by far the most efficient, reliable, and secure solution.
What sort of security do you need with the flat file? Do you need the data in the file to be encrypted, or is the binary file format of an Oracle export file sufficiently obfuscated?
I'd stay away from UTL_FILE here, just because performance is rather poor.
I always get pretty nervous about recoverability when people start moving data out of the database to flat files for long-term archival.
- If you ever change the data model, even slightly, you may not be able to move the data back into the database without modifying your loader. A few years down the line, after a few data model changes, it can be almost impossible to find the documentation to make that change.
- If you do things like change lookup tables over time, reloading data can cause major problems. When you load the data back in, your applications and reports may not treat the old codes properly.
- Making sure that the flat files get stored and tagged properly can be a challenge. When the database gets moved to new system, you have to make sure that all the flat files also get moved around and the the loader scripts are modified appropriately.
