SQL Developer won't show the connections Tab - oracle-sqldeveloper

So SQL Developer won't show the connections tab no matter what I do.
I've tried going through the "view" tab and clicking into the "connections" and I've also tried clicking the new button. I've also tried an uninstall/reinstall, but nothing.
It's probably something simple, but I'm fairly new to it, can anyone direct me or provide any advice?
Any help is really appreciated :)

You can go to the upper tab "WINDOW" and then click "Reset Windows to factory settings".

1.) Save your current SQL connection xml file located in windows 7/8/10: C:\Users\"youruseraccount"\AppData\Roaming\SQL Developer\systemXXXXX\o.jdeveloper.db.connection.xxxxxx
2.)Now delete your SQL Developer Folder and sqldeveloper folder located in: C:\Users\"youruseraccount"\AppData\Roaming\
3.)Now delete the main sqldeveloper folder containing the actual SQL developer application files.This would be located wherever you initially unzipped the SQLDeveloper download.
4.)Download the latest version of SQL Developer and unzip wherever you like.
5.)Launch SQL developer and specify your JDK location.
6.)Copy your connections xml file to your roaming SQL Developer directory here: C:\Users\"youruseraccount"\AppData\Roaming\SQL Developer\systemXXXXXX)\o.jdeveloper.db.connection.xxxxxx
7.)Launch SQL Developer and your DBA view should now be available after selecting view -> DBA

1 ) Select the Windows Menu
2 ) Choose the option Reset Windows to Factory Settings
3 ) Oracle SQL Developer automatically closed and reopened.

Search for the file - windowinglayoutDefault.xml and delete it, and restart SQL Developer.
This file should be present inside a system folder at
windowuserPath\AppData\Roaming\SQL Developer\

I had the similar issue with SQL Developer 4.2, one fine day all the connections pane on left vanished, tried couple options unsuccessfully.
Remedy is
1) Installation of newer version of SQL Developer to the folder of your choice with newer java JDK
2) Import the preference from previous version. DID the TRICK... Good Luck

For me, it worked in the following way:
I just deleted the folder where I had extracted the zip folder and then re-extracted it and then ran sqldeveloper.exe

I exported all my connection to a json file. Then imported the one disappeared and it worked.

This worked for me!!, No need of recreating the connections.

Restore or access workspaces from MySQL Workbench

Using MySQL Workbench 6.3.8 build 1228 CE (64-bit), on Windows 10 Pro, version 1803, build 17134.112.
I want to restore my old workspaces in MySQL Workbench. If that is not possible, I will be happy with just being able to access them as text files.
I guess my laptop had an unusual power-off or reset last night. Normally I put it in Sleep mode, but when I opened it this morning it had reset itself: all applications had quit.
I re-opened Workbench, and got this error message:
saying that my workspaces could not be opened.
I can't get the full text of the error message, so I don't know exactly where Workbench is looking, but using Windows Explorer I could navigate to:
C:\Users\JamesBarton\AppData\Roaming\MySQL\Workbench\sql_workspaces
which looks right to me, and contains .workspace and .autosave directories.
I've backed up the Workbench\ directory, and then tried just removing the .autosave directories, to force the use of the .workspace directories, but when I did that, Workbench still just opened one empty tab. The first .workspace directory contains 95 files, including 45 .scratch files totalling 107kb.
Is it possible to check exactly where MySQL Workbench is looking for workspaces?
Can I force it to open a workspace directly, or at least show me why it can't open a workspace? If that is not possible, can I somehow extract the SQL from the .scratch files? Thanks.
Should be easy to recover the sql from the scratch files which are just plain text files. The sql code is not encrypted. Also you can look in the Workbench log file (see Help menu) to see if there's an error message or similar for a specific file. Could be there's some file corruption. Running the file system checker on that disk also might help.
PS: in Windows you can use the clipboard in system dialogs like this one. Just press Ctrl+C while the dialog has the focus to copy the entire text, including the button captions, to the clipboard. That will hopefully give you the full error message.
Even though my desktop has crashed several times in the past 3 years (either power-related or system) this last time was the first time MySQL Workbench had issues with a workspace (apparently the 2 I had open at the time?). When I investigated why I discovered that all the .info and .scratch files in those workspaces were written with only NUL characters so no easy recovery of my tabs is possible. Grrr.
I will have to recover everything from scratch (haha) by going through the sql_history and possibly log folders and copy/paste as necessary back into the GUI.

AppSrv01 doesnt have write permission

i know that the default profile name when i installed websphere was Appsrv01, I want to create my own AppSrv02 but the location of my IBM Websphere was in C: and i dont have any write permission, i dont have any admin rights also..
using COMMAND-LINE, I want to make my profile folder to be writable, so that my newly created AppSrv02 will be list down in the profile names in my RAD.
Please help me. Thanks
So that's your problem. In order to have a usable profile in WAS, your user must have write permissions. See this link from WAS ND infocenter, it applies to WAS standalone too.
http://www.ibm.com/support/knowledgecenter/SSAW57_8.5.5/com.ibm.websphere.installation.nd.doc/ae/tpro_manage_nonroot.html
If you cannot change the write permissions to this profile, you'll need to create your own. For this, you can either use WAS Profile Management Tool, WAS CLI or you can create your profile using the Configure profiles... link in the WAS server creation wizard you posted. I'd use the RAD way because RAD validates, within the IDE, the proper permissions that you need to create and use the profile within RAD.
First check whether you have admin rights or not if your using User/Guest profile, by creating any new folder in C drive where IBM WAS is installed.
If you have Admin rights, than right click on RAD run as administrator. It should work fine.
If Profile doesnt show up in drop down, Configure new profile and try checking that way.
If you dont have Admin rights better install RAD in any local drive other than C
Running Eclipse with Admin rights and removing the read-only tick for the AppServXX folder/WAS folder couldn't help me... cause I copied the WAS server from another PC :). So for those of you who want to move / migrate your development environment:
I did a search inside the copied WAS, Eclipse and the project's workspace folder for their old paths (with Total Commander, feed the results into a list) and dragged all the files (except the log ones) into my editor (NotePad++) and did a replace in all open documents for the new paths. It's a bit lucrative, but it took only 10 minutes for me and afterwards the WAS server in Eclipse showed the correct profile and it also did start up well.

How can I show local file system browser for Zend Studio 10?

I cannot figure out how to show a local system file tree structure in Zend Studio 10. Nearly all IDEs have this capability. Can someone please tell me how I can browse my local system to open a file without having to create a project?
I don't think this is possible without explicitly creating a project. I think there is a workaround for this if you are using Linux/OSX. Go to Window > Show View > Remote Systems and create an ssh connection to your local host.
Yes, this is an ugly solution but at least its something!

Eclipse says: “Workspace in use or cannot be created, chose a different one.” How do I unlock a workspace?

When I start, Eclipse says "Workspace Cannot Be Locked"
"Could not launch the product because the associated workspace is currently in use by another Eclipse application." or “Workspace in use or cannot be created, chose a different one.”
But I know it isn't.
How do I "unlock" it?
Just delete the .lock file in the .metadata directory in your eclipse workspace directory.
Precaution - If you delete the .metadata folder all preference will be deleted.
I've seen 3 other fixes so far:
in .metadata/, rm .lock file
if #1 doesn't work, try killing the process javaw.exe etc. then rm .lock file
if #1 and #2 don't work, try rm .log file in .metadata/, and double check .plugin/.
This has always worked for me: relocate .metadata/, open and close eclipse, then overwrite .metadata back
The solution boils down to cleaning up the .metadata folder.
Go to TaskManager(Right Click in the Task Bar) and select Processess menu bar and select eclipse.exe and Click EndProcess
Another possible cause of the “Workspace in use or cannot be created, chose a different one” issue is that the real path to your workspace may have changed.
In my case, the real location of the workspace had changed, but I had used a symlink to make it look like it was in the same location. I saw errors in logs indicating that eclipse was looking at the previous "real" location, as opposed to following the symlink, and this was causing the errors.
In my case, I just moved the workspace back to its old location.
There is another case where the path to the workspace may not exist, e.g., if you have imported preferences from another workspace, then some imported workspace addresses may appear in your "open workspace" dialog; then if you didn't pay attention to those addresses, you would get the exact same error once you tried to open them.
Running eclipse in Administrator Mode fixed it for me. You can do this by [Right Click] -> Run as Administrator on the eclipse.exe from your install dir.
I was on a working environment with win7 machine having restrictive permission. I also did remove the .lock and .log files but that did not help. It can be a combination of all as well that made it work.
deleting logs and .lock didn't work but
-clean option fixed it for me.
At times, if you are on Windows, you may not see all the processes - or the culprit process in Task manager. I had to click 'Show process from all users' and there was this java.exe that I had to kill in order to get back my workspace.
Another possible case if none works is to see that there is a running Java application . may be your previous open and close has left unkilled java instances.
Do look for any java instance is running if there are two at least you need to kill one.But ,most of the time i kill any java running :) because that java is using the work space earlier and still will if don't kill it.
Change another work space in case if you want a multiple IDE to use and work on diffrent or same project , but you should import project form workspace after you open your IDE.
i was faced this issue when ever the eclipse is not closed (kill eclipse process the from task manager or computer power off), i was tried below steps, it worked for me.
1) Remove the file names start with ".fileTable" from this folder
C:\eclipse\configuration\org.eclipse.osgi.manager
2) Remove the log files like text files start with numeric names from this folder
C:\eclipse\configuration
3) Open Command prompt(cmd) navigate to this folder
C:\eclipse
type below command
eclipse clean start
For Mac Users:
It could be that another instance of eclipse is running in the background. If so, use either Force Quit eclipse or
ps -ef |grep eclipse
kill -9 pid
to all the eclipse instances, and start the new workspace
Start Eclipse with the option -Dosgi.locking=none.
I got the trick here and it works.
Don't do this unless you know nobody can work on the same file at the same time.
PLease try to end task Eclipse from taskbar. It works for me.
The answer #Boris gave is correct 99% of the time, however it can also happen if you open the workspace in an older version of Eclipse. A workspace imported into/created with Juno will throw this error when opened in Galileo.
Another all-too-common reason for this problem is if you attempt to load a directory on a drive that is no longer connected. For example, Say you program in C:\Code\Java, but occasionally work off of a flash drive, H:\Code\Java. If you do not have the drive connected it can be easy to believe you are trying to load a valid directory without noticing your typo.
Another problem is when eclipse doesn't have write access to your src folder. Change the security permission and make sure "Authenticated Users" are added with all permissions checked but Full Control & Special Permissions.
I had this error after I restarted the system (after a long time. Normally I just make it sleep).
Found out that once I mounted the drives (by clicking and opening it) where project folder is located, and relaunching eclipse, solved the issue for me.
PS: I'm an ubuntu user.
Here are a few steps to solve it the no. 4 step is works for me.
Delete .log files along .metadata folder.
Check the current user permission make sure to check the full control checkbox click apply then OK.
If you run system drive defragmentation or maintenance before you run eclipse editor sometimes original file path are not in their respective path to make sure run "previous version" time before your system maintenance of your drive where the eclipse workbench or something similar to this was saved.
This last option is works for me.
Check the drive letter of your current drive where the code editor was saved. If something unusual e.g before your maintenance your drive letter is K then after defragment or maintenance.
The drive letter is now L hence you should change the drive letter to its original one that is K.
to do this click the ff:
Open control panel
System & security
Administrative tools
Computer management
Disk management
in disk mngt choose the Drive example L
then right click > change drive letter & path > click remove > then ok, open it again then > click add and > choose your original drive letter for that drive then click ok. If you use your computer for a long period of time do restart first to refresh everything.
Choosing a "different one" is actually a pretty easy solution.
I had been running Eclipse as an administrator (sudo eclipse from the command line) because the "workspace" folder was throwing the Workspace in use or cannot be created… error (and running as administrator seemed to be the only solution that fixed it).
A coworker (working on this same issue with me) wanted to run Eclipse by clicking on an icon. So when he ran Eclipse, and the dialogue box came up with the choose your workspace, he just added a "2" to the end of "workspace".
This created a new folder: "workspace2". Eclipse ran fine with that; and I haven’t had any of the locking problems since.
It will occur when you not closed eclipse.exe correctly.
*Open Task manager->End task your eclipse->Now open eclipse.exe it will work.
Hope its help someone.
I have observed one case when eclipse when in forced quit, or Alt-f2 xkilled in linux, an attempt to immediately open eclipse shows that error. Even the metadat/.lock file is not present in that case.
However it starts working after a span of about two minutes
I don't know what's the wrong but I solved by creating a directory directly in c drive(c:\dev) instead of from my home folder (c:\users\me\dev). But I don't have to thinks about it. In my case, it is fresh eclipse unziped instance. I am not able to see .matadata folder in eclipse folder. By God grace, I solved.
The reason this was happening to me (with Photon) was easily fixed by changing an Eclipse general preference:
Window -> Preferences -> General: Uncheck: "Always run in background"
Once you make that change, whenever you shutdown Eclipse, it will no longer leave the javaw.exe process running in the background. I’m guessing this is a bug in Photon (or a bug with using the Amazon Corretto OpenJDK version of Java with Eclipse) that will one day be fixed.
I faced the same problem, but for some reasons the .lock file in workspace was not getting deleted. Even creating a new workspace was also getting locked.
So what I did was cleaning the windows temp folder, the %PREFETCH% folder and %TEMP% locations. Restart the system and then it allowed to delete the .lock file.
Maybe it will help someone.
It seems your workspace is used in Java TM, Open task manager and close eclipse.exe and java TM process.
What worked in my case was restarting the system. (ubuntu 20.04)
If anyone have come here with a STM32Cube related issue, which apparently is based on Eclipse and has the same problem, none of the above suggestions worked for me, and here is how I fixed it, for Linux, although I suppose you can find the corresponding paths in Windows as well.
In the $HOME directory, go to .eclipse/com.st.stm32cube.ide.../configuration/settings
The file org.eclipse.ui.ide.prefs contains few options including the recent workspace path, and whether it will prompt you to select a workspace at the startup. Either modify the path for RECENT_WORKSPACES, or enable SHOW_WORKSPACE_SELECTION_DIALOG.
In my case, there was a space right before the workspace's location C:\. I removed that space and it was enough :)

Deleting files on remote server

I have a PHP project in NetBeans with remote files (over sftp). When I create, modify anything these changes happening both locally and on my web server. However when I'm trying to delete a file or a folder it gets erased only locally. What could be the problem?
Permissions seems to be ok, all files belong to the user I'm using to access the server.
I'm using Netbeans 6.9.1, default configuration, all updates installed.
Netbeans does not have a synchronization function. It is limited to downloading and uploading files. What you can do is to use some external tool, for example WinSCP is capable of synchronizing local and remote directories.
I read what you wrote... but I think it could be a permissions problem.
I also use NetBeans and when I delete a file from the project window it first erase it locally and then syncs with my server.
I login through sftp (using vsftp) as root, which is a bad thing, but you could try this too to be sure if it's a permission issue.
You mistakenly turned off the settings. Please follow these steps:
Right click on the project name
Select properties
From the list of the left select 'Run configuration'
On the left almost down, look for the setting 'Upload files:'
Make sure you set that to 'On Save'
All the best man
