SQL Developer 1.5.5 installs but won't connect to Oracle DB

An earlier version I'd been using for years just went dead on me, nearly crashing my PC in the process.
I installed 1.5.5 with its own JDK, and it launches without errors, but when I try to create a new connection, it gives me this crap: "no ocijdbc11 in java.library.path".
A perfect example of a completely useless error message. What's a "java.library.path"? Where is it? How do I fix it?
I couldn't find any uninstall utility for SQL Developer, so I just deleted the 'sqldeveloper' directories for both versions and re-installed. Same result, same useless error message.
I thought I might try this forum while I'm installing TOAD. Any suggestions? Anyone seen this before?

If you're using TNS, try using the Basic connection type.
If that still doesn't work, you can try tricking sqldev by changing your ORACLE_HOME within a batch file inside sqldev's install folder. This would force using the supplied thin driver:
set ORACLE_HOME=%CD%
start sqldeveloper.exeHope that helps,
K.

Did you create a database though?
Installing Oracle doesn't necessarily mean you have a database.

Need to Install Safari 6.0.2 on a white Intel core duo iMac. Had to throw out 6.0.3 because of conflict with required software. Downloaded wrong version that was for Mountain lion (I am running 10.7.5). It installs but won't open.

Of course I can't throw it away since I get a message it's part of the sytem. I can show package contents and throw those away, but evidently not a good idea!!

We use an Airport Extreme in my office, which works fine for me. Occasionally we need to have more than one computer running on it, but for some reason it won't connect to the internet. It says we have internet, but won't connect to wifi. What's going on?

I use my computer everyday in our office and have no issue connecting to the internet/wifi, but when my boss comes in and tries to connect it doesn't work. It tells her she has internet, but won't connect to the wifi. We've tried a few different tactics(the basic ones I've seen on here), but nothing seems to be working for us. My computer automatically connects to our wifi.
Just recently the Airport Extreme has started with the blinking amber colored light on the front, which I believe means something is wrong? Can anyone help us figure out what's going on and why we can't get my boss' computer to connect as it should?
Thank you!

Here's an update:
Now the light is not blinking. It's a solid, consistant green. I don't know if it helps to narrow it down or anything, but I just figured I'd mention it.

Glad to hear it is all straightened out. You are right about the upgrade cost. That is one reason why Adobe switched to monthly licensing—no more upgrade cost <g, r, & d>. Of course we do have nearly monthly product upgrades. It is almost like playing whack a mole.

SQL Developer not starting - new installation

I installed Oracle 11g on Windows 8, and am having problems with SQL developer starting. I have tried to debug but not a clue what I am looking for. I really could use some help. It is a 64 bit installation - and seems to be OK as I can connect to the DB in SQL plus. Thanks a lot!

Rosetta Stone TOTALe (Spanish) 4.5.5 Fatal Application Error 1141 Installs But Won't Launch After MacBook Restarts

I have a MacBook Pro running OS X 10.9.4 (Maverick) and am trying to add Rosetta Stone Latin Am Spanish to this laptop, after having successfully installed it several years ago on a older MBP.
I was given the latest download file TOTALe 4.5.5 by Rosetta Stone Support for this purpose. It will install fine and work, immediately upon installation, but when I shut down and restart, I can no longer launch the program and get the Fatal Application Error 1141 code instead.
I have been through this issue many, many times with Rosetta Stone Support already and have followed, alone and with them, the troubleshooting link set up for this problem without success. (Here is the link: https://rosettastone.secure.force.com/en/language-learning/articles/Error-1141-a ppears-when-I-start-the-Rosetta-Stone-TOTALe-application#macdiv) Rosetta Stone has run out of ideas to resolve this issue. (I have saved about 10 chat session transcripts where the support people have me run through the same steps over and over, despite my informing them of the previous lack of success in following these steps.)
My OS X is up to date. I am wondering if anyone else has experienced this problem running Maverick.
Any thoughts would be greatly appreciated.
P.S. This is a relatively new MBP and the only add-on software other than Rosetta Stone is Microsoft Office.

I have the same problem. Back in 2011 I bought Rosetta and got the very same problem, talked and talked to their support to no avail. On that instance they returned my purchase money. This time around I asked beforehand if the software was totally compatible with Yosemite and they said yes. I just got it, tried to unit and got error 1141 again. It is very frustrating! I will talk to them again but my hopes are very low. I guess one needs to understand that the software is crap!

SQL Developer - Cannot see list of tables in my connection

Hi - when I downloaded and started to use the SQL developer tool, once I connected, I could see all of the tables/columns in my connection on the left side of the tool, and I had my query panel, results panel, and SQL history stacked on the right. Suddenly something has changed, and I cannot see the list of tables, etc. in my connection anymore, so I have to rely on memory and SQL history to remember the table and column names. It has to be "hidden" somehow, but view-connections does not help, and trying to click and drag windows doesn't uncover it either.
Any suggestions?
Thanks!

Probably better to ask in the SQL Developer forum here: SQL Developer
I've been trying the version 2 beta though and it has quite a few bugs in. Table browsing is working fine for me, but all my functions and procedures have disappeared from the tree view. It does odd things with code formatting too.
I don't think it will be supplanting trusty old command line SQL Plus for me yet any time soon...

SQL Developer 1.1 Query Builder does not display connection tree

I have installed SQL Developer 1.1 on a PC running Windows XP SP2. I am connecting to Oracle 9.2.0.7.0.
After connecting to the database, I right click in the SQL Worksheet and select Query Builder and when the new window is displayed, there are no tables to select from.
What is causing this?

Hi Antony,
Upgrading from SP7 to SP9 fixed a lot of problems for me! It's worth trying.
Problems solved for me:
Page requests take about 2 minutes to display page (now within a few seconds)
KM SQL logging (30-50Mb per minute) problem fixed.
There are some problems upgrading to SP9, but searching this forum will help you in finding some solutions for this

Noel

Time capsule produces a signal, but won't connect or backup

I have looked at some of the other discussions here; some are similar, but I can't find an answer.
I have a TC, Macbook Pro and an iPhone 4, all between 6-10 months old. My problems started when I turned on all my stuff after being away for 4 weeks over the summer.
My Macbook pro's AirPort recognises the TC - I have a 'full signal' reading at the top of the page. However, when I try and connect to the internet, I'm told it can't connect to the server. If I just keep trying, re-entering addresses (from the scroll-down bar, so always exactly the same), it eventually connects and I have a great connection, which I can use to watch movies/download stuff no problem. Why is it so **** illogical? Why does it connect on the 20th attempt, and not on the first? This happens however long the computer has been on, and regardless of when I last connected to the internet.
The biggest problem is that I have a Vodafone 'Sure Signal' signal booster attached to the TC. Without it, I get no phone signal. The Sure Signal does not recognise the signal from the TC at all. I have done factory resets on both - individually and together, and nothing has changed. I have turned the Sure Signal off, but the TC still doesn't work properly.
My iPhone won't connect either. It too shows a 'full signal', but when I try and connect it says connected/not connected alternately about every 1 second.
The TC is connected to the internet via a cable from my landlord's router, next door. They have perfect signal. They also have a signal booster in their house, which used to interfere with my TC (when it worked). I changed the channel on my TC, and now, when it connects, there is no interference.
Please can someone enlighten me - I have worked though every thing I can, and I can't go any further because I can't see any logic to the problem.
** Since these problems have started, the TC has not backed anything up - I can't get it to back up, whatever I've tried.
** Each time I have re-made my network, when I open Airport Utility, it says 'no wireless devices recognised', and I have to re-start the TC in order to be able to do anything to it.

Try changing the Firewall setting:
mDNSResponder - Allow incoming connections
Background:
My Time Capsule was working perfectly in Leopard.
When I upgraded to Slow Leopard, Airport Utility was no longer able to see the Time Capsule - although my Mac (MBP) was still able to connect to the wireless network and out onto the Internet.
The next day or so I upgraded to Lion (Snow Leopard was only installed to get App store) - the situation remained the same.
From another Mac (MB - still running Leopard) Airport Utility was still able to connect to Time Capsule.
I edited the firewall settings on my Lion MBP:
The mDNSResponder was set to "Block incoming connections".
I changed this to "Allow incoming connections".
Airport Utility was then was then able to see the Time Capsule (I can't recall now if I needed a reboot after changing this).
HTH.

Forgot password.Tried to wipe by using Find my iPhone but won't connect to wifi even though it is turned on in the lock screen.Then tried to restore through iTunes but couldn't because Find my iPad on. Removed the iPad but iTunes still not working. Help!

My daughter stopped using her iPad when she got an iPhone for Christmas. It has been over one month and she has forgotten her passcode. I tried to wipe it via Find my iPhone but it won't connect to the wifi even though wifi is switched on on the lock screen. I then tried to restore it through iTunes but was unable to becuase Find my iPhine was switched on so I removed the iPad from the device list only to find that it didn't solve anything with the iTunes situation and it still won't connect to the wifi. I ahve tried turning wifi on and off, tried leaving the house and re-entering all to no avail. Is there any other way to restore the iPad????

FORCE IPAD INTO RECOVERY MODE
1. Turn off iPad
2. Turn on computer and launch iTune (make sure you have the latest version of iTune)
3. Plug USB cable into computer's USB port
4. Hold Home button down and plug the other end of cable into docking port. Do not release button until you see picture of iTune and plug (very important)
5. Release Home button.
ON COMPUTER
6. iTune has detected iPad in recovery mode. You must restore this iPad before it can be used with iTune.
7. Select "Restore iPad"...
Note: Data will be lost

My airport extreme shows a green light, but won't connect to the internet.

I have an airport extreme, and it stopped working one day, so I reseted it and it's not connecting to the internet now. It's showing a green light, however, it won't connect to the internet. I live in an apartment complex, so I don't have a cable modem. The router is directly connected to the wall via ethernet. I had the ports checked by connecting the ethernet cord directly to the computer, and the internet is working fine. I tried resetting the router, but it still doesn't connect.

Your problem is typical Yosemite network.. just reboot the Time Capsule.. no luck reboot the network.. do a restart in correct order.. modem.. wait 2min.. TC .. wait 2min.. clients.
No luck then do a full reset of the TC and setup in a way that Yosemite can cope with.
Start from a factory reset. No files are lost on the hard disk doing this.
Factory reset universal
Power off the TC.. ie pull the power cord or power off at the wall.. wait 10sec.. hold in the reset button.. be gentle.. power on again still holding in reset.. and keep holding it in for another 10sec. You may need some help as it is hard to both hold in reset and apply power. It will show success by rapidly blinking the front led. Release the reset.. and wait a couple of min for the TC to reset and come back with factory settings. If the front LED doesn’t blink rapidly you missed it and simply try again. The reset is fairly fragile in these.. press it so you feel it just click and no more.. I have seen people bend the lever or even break it. I use a toothpick as tool.
N.B. None of your files on the hard disk of the TC are deleted.. this simply clears out the router settings of the TC.
Setup the TC again.
Then redo the setup from the computer with Yosemite.
1. Use very short names.. NOT APPLE RECOMMENDED names. No spaces and pure alphanumerics.
eg TCgen5 for basestation and TCwifi wireless name.
If the issue is wireless use TC24ghz and TC5ghz with fixed channels as this also seems to help stop the nonsense. But this can be tried in the second round. ie plan on a first and second round of changes to fix this.. hopefully.. I will point out other steps that can be round2.
2. Use all passwords that also comply with 1. but can be a bit longer. ie 8-20 characters mixed case and numbers.. no non-alphanumerics.
3. If the TC is main router you can skip this point. This is only an issue when the TC is bridged.
Ensure the TC always takes the same IP address.. you will need to do this on the main router using dhcp reservation.. or a bit more complex setup using static IP in the TC. But this is important.. having IP drift all over the place when Yosemite cannot remember its own name for 5 min after a reboot makes for poor networking.
4. Check your share name on the computer is not changing.. make sure it also complies with the above.. short no spaces and pure alphanumeric.. but this change will mess up your TM backup.. so be prepared to do a new full backup. Sorry.. keep this one for second round if you want to avoid a new backup.
5. Mount the TC disk in the computer manually.
In Finder, Go, Connect to server from the top menu,
Type in SMB://192.168.0.254 (or whatever the TC ip is which you have now made static. As a router by default it is 10.0.1.1 and I encourage people to stick with that unless you know what you are doing).
You can use name.. SMB://TCgen5.local where you replace TCgen5 with your TC name.. local is the default domain of the TC and doesn't change.
However names are not so easy as IP address.. nor as reliable. At least not in Yosemite they aren't. The domain can also be an issue if you are not plugged or wireless directly to the TC.
6. Make sure IPv6 is set to link-local only in the computer. For example wireless open the network preferences, wireless and advanced / TCP/IP.. and fix the IPv6. to link-local only. Do the same for ethernet if you use it.
There is a lot more jiggery pokery you can try but the above is a good start.. if you find it still unreliable.. don't be surprised.
You might need to do some more work on the computer itself. eg Reset the PRAM.. has helped some people. Clean install of the OS is also helpful if you upgrade installed.
Tell us how you go.
Someone posted a solution.. See this thread.
Macbook can't find Time Capsule anymore
Start from the bottom and work up.. I have a list of good network practice changes but I have avoided Yosemites bug heaven.
Yosemite has serious DNS bug in the networking application.. here is the lets say more arcane method of fixing it by doing a network transplant from mavericks.
http://arstechnica.com/apple/2015/01/why-dns-in-os-x-10-10-is-broken-and-what-yo u-can-do-to-fix-it/
Same thing applies to the Airport Extreme or the Express if used as router.. just replace TC in the instructions with AE.

Airport used to work fine, but won't connect to internet now

Hello. I bought my Macbook pro about two weeks ago and never had problems with my internet connection. I moved last week to another city, and had my wi-fi installed today. My brother has a Powerbook G4 and it worked fine with the new connection, but my Mac won't; it won't connect automatically when I turn the computer on and when I click on "open network preferences", nothing happens. I already got connected by clicking on Network Diagnostic in Safari, but i'd like to do so without going through all that everytime I need to get on the internet.
Can anybody help me to fix this problem? I'd really appreciate that. Thanks in advance.

Tell us about your network. How are you connected to the internet? Cable modem, DSL?... Is there a router involved? Which one is it? System Preferences>Network>Show:Airport>TCP/IP are you getting an IP address?
