Forms/4GL Tutorial Returns Cannot find server or DNS Error
Hi:
I am trying to plow through this tutorial (10.1.3.1.0) and when I run the SRList.jpsx page I receive the error: Cannot find server or DNS Error. The URL produced by JDeveloper is:
http://192.168.99.36:8988/SRTutorialADFBC-UserInterface-context-root/faces/app/SRList.jspx.
Any suggestions?
I've culled the forums and the Web, and cannot find a match. The only nugget that I can add is that I'm using JDeveloper with the OA Framework extension. I have been successful creating pages with OA Framework and executing them. Is there some incompatibility with OA Framework and ADF?
Any help is greatly appreciated!
Mchrist,
You cannot use the OA Framework download to develop ADF apps.
I would create two batch/command files: in each one, set JDEV_USER_DIR and any other environment variables to point to a proper place and run the JDeveloper.
Just unzip JDev and OA Framework to separate locations and ensure that the user directory for each is in a separate location as well.

Intermittent "Cannot find server or dns error"
We are getting "Cannot find server or dns error" intermittently. It happens most frequently using internet explorer on https. Anyone else getting this or have any suggestions?
(I have logged as TAR 1525537.999)
nullAfter many, many hours or research and corresponding with other
Oracle resources, we resolved the issue. We still receive the
"Cannot find server or DNS error" but with much, much less
frequency.
Here are the complete details:
Environment:
Windows NT 4.0 SP 6
Oracle 9iAS 1.0.2.2
Oracle 9iAS Portal 3.0.9.8.0
Oracle 8i Database 8.1.7.0.0
Apache HTTP Server: 1.3.19 (win32)
mod_ssl: 2.8.1
OpenSSL: 0.9.5a
SSL port: 443
Problem:
We were running into the following error intermittently (but very
frequently) when accessing pages in the Oracle Portal application
with SSL enabled:
"Cannot find server or DNS error" at the bottom of a "Page cannot
be displayed" error page.
Resolution:
7 Applied patchset for Oracle8i 8.1.7.1.1 (to database client and
server)
7 Applied patchset for Oracle8i 8.1.7.1.5 (to database client and
server)
7 Applied patchset for Oracle Portal 3.0.9.8.1
7 Implemented solution for Oracle Bug No. 1822053 (HTTP 404 Doing
Portal Development) by changing (and un-commenting) the following
line in our Apache http.conf file:
From: #SetEnvIf User-Agent ".*MSIE.*" nokeepalive
ssl-unclean-shutdown
To: SetEnvIf User-Agent ".*MSIE.*" ssl-unclean-shutdown
7 Implemented solution for Oracle Bug No. 1821195 (When uploading
large file using modplsql & SSL error reading data from client)
by replacing the existing ApacheModuleSSL.dll file with the
patched file referenced in the bug details.
Note: Bug No. 1821195 is for Oracle9iAS 1.0.2.2. It references
Bug No. 1773627 for Oracle9iAS 1.0.2.1.
I feel the biggest help was finding out about Bug No.
1821195/1773627. We were provided the bug details by a local
Oracle technical consultant, Dave McMarlin, referred to us by the
Oracle Joint Staff Account Manager. That solved our problem with
receiving the noted error message when we tried to add items to
the content area. Applying the change to the http.conf file
identified by Bug No. 1822053 (removing the nokeepalive entry) in
combination with the Oracle8i and Oracle Portal upgrade seems to
have solved our problems with the other intermittent occurrences
of the noted error message.
According to the details for the ApacheModuleSSL.dll patch, there
was mention of a bug in the "select" function in Windows NT 4.0:
"When checking a socket, if data can be read without blocking,
select () returns yes, but when actually reading from the socket
with recv(), that function returns WSAEWOULDBLOCK, which says
that reading would block. It seems that this problem does not
occur in usual operation, but only in an SSL enabled Apache
(modssl or apache-ssl) with https. The code for WIN32, which
handles writing to a socket, already contains a workaround for
this. The code for reading from a socket did not have a
workaround."

Problem with wrt54gl Cannot find server or DNS Error
Hello,
I am having problem with wrt54gl roouter. I have windows 2K professional that connected trough the wire. The browser (and other tools) is periodically loosing connection for around 30-60 seconds showing "Cannot find server or DNS Error". after refreshes it comes back. If I connect PC directly to internet without router I never have a problem. I have put statical resolution of dns servers(3 of them) and ip does not help. I switch between ports on pc and router site, change the cable, remove antivirus, put latest windows updates, use different browsers. Disable anable 2d network card (2 on mother board).
Any suggestions?
ThanksHi… Login to the setup page of the router and reduce the MTU to 1365. Upgrade or re-flash the firmware if needed.

IE returns "Cannot find server" page during Servlet processing
I have 2 JSP applications, that require a certain amount of server processing before they complete. For small amounts of information, both of these applications work fine. However, with larger amounts of processing, IE seems to timeout or have a problem maintaining its session and returns with "Cannot find server" - the actual server processing continues meanwhile. This only happens with IE - other browsers maintain persistence. The "timeout" is always consistent - 5 minutes or so with one of the applications, 13 minutes with the other.
I can find no IE configuration that controls this. Since this doesn't happen with other browsers, is this an IE problem or a design issue with the application that doesn't manifest itself with other browsers ?I wouldn't call it an IE problem. I would call it a design issue -- you should not take that long to return a response to the browser. Instead, you should return an immediate response that says something like "Your request has been received for processing", and have some other thread processing requests off-line. That other thread should send a notification (by e-mail?) to the user when the request has been processed, including a link where the data can be accessed.

For the last few days I am having a lot of problems with my Btinternet email - main one is that 7 out of 10 log ins I get a "Cannot find server" message. This morning I haven't been able to get in at all so far. (and yes, I am trying to log in via the link on the BT.com home page). I also get kicked out of email most times I click on Inbox and have to log back in again which is incredibly frustrating.
All this is since my laptop insisted on installing IE 11 but I don't know if there is a connection.
Any suggestions?If I go to the 'My BT' website and click on the 'Email' logo at the top right of the screen I get the email logion screen.
After typing my login details my web browser tries to display page
http://uk.mg.bt.mail.yahoo.com/
but it fails and I get an error message saying "502 - Cannot find server or DNS Error".
Has anyone got any ideas how I can access my emails? -
"Cannot Find Server" Constant Error Message
I've been having this problem for quite some time. I will attempt to connect to a website only to wait forever and then get a "Cannot find server" error message. It's not just with one site, it happens with many.
It's also random. Sometimes everything connects fine and fast, and then inexplicably I get "Cant' find server" for sites like Facebook, Amazon, even Apple. It can start working again for a few minutes and then in an instant I'm getting error messages again.
However, my email always works fine.
And this is NOT a Safari problem. I also get the same trouble when I switch to Firefox or Explorer. My ISP says it's an Airport / Mac issue since it all works fine if I direct connect to the laptop and because my email is also working.
In addition, when I'm having this problem, my iPhone also cannot connect to the WWW but can get email.
I've tried powercycling the modem and the airport numerous times. It's really becoming a pain.
Any thoughts?Me too I tried everything. I am an Apple fan with 2 computers,3 iPods. I have no idea what the problem is. I had to re-run the disk each time to find the internet. Finally tried a Linksys Grouter worked first time-laptop anywhere in the house strong signal. I have had similar problems with an Airport Express-never got it to work-so tried the Extreme. I returned it-I didn't want to but I just could not get it to work.

Safari cannot open facebook, cannot find server.. why ?
When I try to go to the facebook page, Safari cannot open it, says "Safari cannot find server"..."Safari cannot conect to server".. etc etc
Double-click anywhere in the line of text below on this page to select it, then copy it to the Clipboard (command-C):
www.facebook.com
Launch the Network Utility application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Network Utility in the icon grid.
Step 1
Select the Lookup tab and paste into the address field (command-V). Press return. Post the output that appears below – the text, please, not a screenshot.
Step 2
Select the Ping tab and do the same. Please enter the same input as you did in Step 1. Don't use the output of Step 1 as input to Step 2.
Important Note
Some web browsers and mail clients will automatically convert a domain name such as "www.example.com" to a clickable URL, such as http://www.example.com. That will interfere with the test. If necessary, edit the input in the Network Utility window to remove any added characters. -
HP Laserjet 2015 ..."Cannot Find Server"
I am having trouble in having my printer be a... "Network Printer"…. It is a HP Laserjet 2015 Printer.
I have a Mac OS version ~ 10.8.2 on my Apple computer.
If i have the printer connect directly to the computer via USB, (with no network) the printer works fine, but if I try to set up a network using an Ethernet Cable from the Printer Server to the Linksys E1200 Router, then I am unable to print. I get a page with ERROR messages.
I am using a HP JetDirect 175x External Print Server
When I run "Network Diagnostics"…. I get a….. "Cannot find Server"….. along with the message below….

I have since removed the Printer Server, and found that I can simply put the USB Cable from the Printer to Computer 1, and Computer 2 will see it on the Network..... so I didn't even need that Printer Server in my setup as I had been informed.

The printer that I have does not have network capabilities built in.... to have the network capabilities, HP says an additional piece of equipment must be used.... in my case, an HP JetDirect 175x Print Server... I found a used one on eBay that was inexpensive, so I purchased that, and have been trying to configure it to my computer and printer for about 5 hours now.... all I got were error pages.
I have an older iMac (2008), and I wanted the ability of the use of one printer for the new and old computers.
After I read your advice, I disconnected the HP JetDirect 175x Print Server entirely, and used just a USB cable from the printer to the computer.
The printer worked great from my new computer, but I still wanted the ability of using the printer with the older computer (Wi-Fi). I went into the Print & Scan of System Preferences, and for the heck of it, I clicked the "Printer Sharing" box.
I went to the old computer, and for the heck of it, I tried printing something.... LO & BEHOLD it worked.
I don't know how it works, because as I said before, the printer is not network-ready. When I bought the printer several years ago, there were two printers of that model on the shelf. One was a HP 2015, and the other was a HP 2015n.... (n meaning network). At the time I didn't think that I would ever need a network printer, which was more expensive, so I purchased the non-network one.
Now I am truly bewildered as to how I am able to print from both computers without the HP JetDirect 175x Print Server.
Do you, or anyone else have the answer to that????

Cannot find server error trying to download Migration Workbench
I've been trying to download OMWB for the last 4 days, from Oracle Migration Workbench Downloads / Release 9.2.0.1.2 for Microsoft Windows 98/NT/2000/XP page.
Keep getting 'Cannot find server' and 'Page cannot be displayed' errors in Internet Explorer.
Is this the correct URL:
http://download.oracle.com/otn/nt/omwb/92012/omwb_92012.exe
I downloaded and used the previous version of OMWB. Was very satisfied with it. Unfortunately, I had to rebuild my hard drive and lost OMWB.I suggest that you retry, maybe there was some network glitches... If you follow the links from OTN you should be able to download no problems. Did you try the split downloads as an alternative?
