Export to excel in web with oracle forms 10g
we have an application running on web with oracle 10g forms in windows server 2003. We use webutil to generate excel. But it is terribly slow when its is run on web. When run locally its fine...
PLS suggest.....
Thanks,
RekhaCLIENt_OLE transfers lots of small packets over the network,that's what it makes slow. What you could do.... write your own javabean which uses jacob and "aggregates" the low-level OLE-commands to somehow logical commands like "writeValuetoCell"

How do I access my external drive over the web with my iPhone. The drive is attached to my Time Machine. I am new to Apple and am trying to get all my stuff working together.
This is not a supported feature of iPhone or Time Capsule.

I have a MacBook Pro, which I just bought in August.
When I try to watch videos on my computer, a message pops up saying, "You are currently browsing the web with Google Chrome and your Video Player might be outdated." I know it's a pop up, but I don't know how to get rid of it and watch videos on my computer. I did look it up online and I downloaded the TSM Adware Removal Tool, which removed some adware files. Then I also downloaded Bitdefender Virus Scanner from the app store to scan my entire computer - nothing came up.
Please help me solve this problem. Thanks.The update alerts are fake, and are intended to dupe you into installing malware or disclosing private information so that your identity can be stolen.
You might get the alerts when visiting a website that has been hacked. Don't visit the site again. If applicable, notify the site administrator of the problem, but don't send email to an unknown party.
If you get the alerts when visiting more than one well-known website, such as Google, YouTube, or Facebook, then they're almost certainly the result of an attack on your router that has caused you to get false results from looking up the addresses of Internet servers. Requests sent to those sites are redirected to a server controlled by the attacker. It's possible, but less likely, that the DNS server used by your ISP has been attacked, but you should assume that the router is at fault until proven otherwise.
The router's documentation should tell you how to reset it to the factory default state. Usually there's a pinhole switch somewhere in the back. It may be labeled "RESET." Insert the end of a straightened paper clip or a similar tool and press the button inside for perhaps 15 seconds, or as long as the instructions specify.
After resetting the router, quit the web browser and relaunch it while holding down the shift key. From the Safari menu bar, select
Safari ▹ Preferences... ▹ Privacy ▹ Remove All Website Data
and confirm. Do the equivalent if you use another browser. Open the Downloads folder and delete anything you don't recognize.
Then go through the router's initial setup procedure. I can't be specific, because it's different for every model. The key points are these:
1. Don't allow the router to be administered from the WAN (Internet) port, if it has that option. Most do.
2. Set a strong password to protect the router's settings: at least ten random upper- and lower-case letters and digits. Don't use the default password or any other that could be guessed. Save the password in your keychain. Any password that you can remember is weak.
3. If the router is wireless, or if you have a wireless access point on the network, use "WPA 2 Personal" security and set a different strong password to protect the network. If the router or access point doesn't support WPA 2, it's obsolete and must be replaced.
During the time the router was compromised, you were redirected to bogus websites. If you ever connected to a secure site and got a warning from your browser that the identity of the server could not be verified, and you dismissed that warning in order to log in, assume that your credentials for the site have been stolen and that the attacker has control of the account. This warning also applies to all websites on which you saw the fake update alerts.
Check the router manufacturer's website for a firmware update.
If you downloaded and installed what you thought was a software update, ask for instructions. -
Opening PDF files on the web with IPad
Hi everyone
I am having difficulty opening some (but not all) pdf files on the web with my IPad. When I click on the icon it comes up with approx half of the first page of the document, but nothing else. It also does not provide an "open in" bar. Any thoughts on what is going on here?
With thanks, Mike.Thank you for following up. We often have people reporting similar problems and I suggest they follow up with the website owner but I rarely hear back from the original poster so I'm never sure that this is indeed the problem. Ironically, serving a document for mobile is almost easier than serving it to a desktop browser because there are no plugins to get in the way. That said, a lot of website owners have gone through pains to do plugin detection and user authentication and authorization and mobile represents another case that they would need to handle on top of what they already do.

HT201335 when i watch movies from the web with airplay on my apple tv stop every 2 minuts
when i watch movies from the web with airplay on my apple tv stop every 2 minuts
I have a similar issue with my Home Sharing. Everything plays just fine on my Apple TV except when I try to play a movie using Home Sharing. If I choose the same show or movie from the Purchased section of iTunes it works just fine but nothing ever loads for me on Home Sharing.
Not the exact same issue, but very similar. Good luck, I'm hoping to learn something here too! -
The network adapter could not establish the connection with Oracle
I installed Oracle in my laptop (windows 2008), and install Hyperion 11.1.2, when I configure Hyperion, it pops up with "the network adapter could not establish the connection with Oracle"?
Hi,
This usually means that the connection details you have put in for Oracle are incorrect or Oracle can not be contacted.
Double check your configuration connection details and make sure you can access Oracle using them details.
Cheers

How can i do the RAC with Oracle 9i ?
How can i do the RAC with Oracle 9i ?
The Oracle 9i has a RAC(Real Application Cluster)module , please who can tell me how can i let it working .
Which hardware the RAC need's
Thank All ,
[email protected]That is right you need atleast 2 boxes. The two servers will use the same hard disks.
The concept is an extension of OPS(Oracle Parallel Server).
Basically, you install Oracle Server Software on both the boxes, One database will be shared by both the servers. You can access your database through the Server1 or Server2. If Server1 fails then the Server2 will take over all the connections. You can add or remove any servers to and from the cluster any time you want with out impacting your production.
They share load, reliable, scalable.... -
Deploying application to the web with Developer Server
Hi everyone,
Does anyone out there has any notes or step-by-step configuration
guide on deploying application on the web with Developer Server
only (not with OAS)? I know that you can use it with Microsoft
IIS 3.0 or 4.0 (as the web server) but don't know how to set it
up. Appreciate if someone out there could help. Thanks.

I am getting this pop up message: You are currently browsing the web with and it is recommended that you update your video player to the fastest version available. Please update to continue.
How do I get rid of it? I have tried searching the web and I have only seen solutions for chrome and firefox. Thanks.the link to the page is below

Anybody else tired of not being able to play half the videos on the web with your Apple products - just a rant. Thanks
Constant problems: asking for password, not retrieving mail from the server,leaving things in the outbox. Then it can be fine for days. iPad and iPhone apps sometimes hang for a bit as well.
A friend just bought an iMac and has had nothing but trouble with ROGERS mail. Support guy walked us through the whole set up today and everything was fine for a while and then it just quit.
I am wondering if having an IPad, computer and phone all communicating with server at the same time causes problems. -
Hi everyone.
I've been trying to learn how to make a web crawler in java following this detailed albeit old tutorial: http://www.devarticles.com/c/a/Java/Crawling-the-Web-with-Java/
The SearchCrawler class they feature can be found in two parts:
First part: http://www.devarticles.com/c/a/Java/Crawling-the-Web-with-Java/3/
Second part: http://www.devarticles.com/c/a/Java/Crawling-the-Web-with-Java/4/
I don't want to copy and paste the code because it is really long and an eyesore if viewing here.
I get a lot of errors when compiling of which I do not understand. The majority of the errors (62 of them to be precise) are "class, interface or enum expected" errors, with the remaining few being "illegal start of type" and "<identifier> expected" errors.
Can someone here perhaps take a look at it and compile it and see if they also get the same errors? I realise it is an old tutorial but there are hardly any detailed resources I can find for java web crawlers.
Thanks.Odd I can't seem to log into my account. Never mind.
I have used java before, the problem here I suppose is I'm not good enough to spot what's the problem. The code seems fine bracket wise and it has really left me stumped.
If someone code put it in their editor and attempt to compile and see if I'm not the only one that's having a problem.. that would be much appreciated.

We are using Oracle ERP in our company which is a web based ERP system. I am using firefox to work in ERP for convinieince pf working and using internet at the same time. This requires a plugin provided by oracle oajinit.exe to be installed in Plugins it is a JAVA plugin which opens the ERP Screens. This works fine in versions prior to 3.6 version of firefox. However, after upgrading to 3.6 version the forms do not open and firefox crashes. Due to this i am not able to upgrade to the latest version else i'll have to operate the ERP in internet explorer and using firefox for browsing which i do not want. The plugin used for the ERP is "* JInitiator 1.3.1.18 for Netscape Navigator (DLL Helper)"
Firefox 3.6 needs the Java Second Generation Plugin which comes with newer versions than 1.6.0_03 - update Java, the latest version is 1.6.0_22
