Lost settings of SQL Developer

Hi Buddies;
I'm using SQL Developer, and inadvertently, I changed the configuration. By this, I mean, initially when I enter to SQLDeveloper I got the window with the conections at the left, and at teh right i got the windows to execute queries or to see tables contains.
But now, when I enter, initially I got a big window with the conections, and when I open a table or I wan to execute a query, I need to look for the especific window, and it's not easy.
How can I restore the initial configuration? I was thru Universar Installer, trying to delete the SQLDeveloper, but I couldn't find out under which section it's.
Any idea what can I do, to solve this problem?
Thank you very much.

To reset the layout, delete the (hidden) \Application Data\SQL Developer\system2.1.0.63.73\o.ide.11.1.1.2.36.55.30\windowinglayout.xml under your Windows user profile. It will be recreated at next startup.
Hope that helps,
K.

Migrating SVN Settings to SQL Developer 3.1EA3

I had SVN set up in SQL Developer 2 and it was working just fine. When I installed SQL Developer 3, I migrated the settings from SQL Developer 2, but the SVN settings did not move over with it. In addition, when I attempt to set up SVN in SQLDev3, it sees it as a new repository and attempts to overwrite my existing local SVN repository.
What is the recommended way to migrate an SVN repository from 2 to 3?
Thanks!
Jimmy

Here's the solution (in case any one else has had the same problem).
You need to export your SVN settings from the previous version of SQL Developer and import it to the current version. In my case, it was version 2.1 to 3.
Right click on Subversion in the Versioning Navigator, and Export connection.
Then, in the new version of SQL Developer, right click on Subversion and Import connection.
Done.

How to get these settings in sql developer

as per this link, when I selected my rows in sql developer am not getting any of the options shown in the screen shot of the link,
my sql developer is Version 3.2.20.09 windows 64 bit, to use this options do I need to do any settings?
http://www.thatjeffsmith.com/archive/2013/02/how-to-copy-only-column-headers-from-query-results-in-oracle-sql-developer?
when I highlight and right click am getting only
a) Save Grid as report
b) Single record view
c) count rows
d) FInd/highlight
e) Export

Once you have identified the desired column headings by highlighting one or more related data cells in the results grid, position your cursor over any column heading and right-click to get the context menu shown in Jeff Smith's blog.

SQL Developer 2.1 loses "recently used" type settings

I'm having an issue with 2.1 that I did not have with 1.5.5. Each time I start SQL Developer all my "recent" settings go back to default. I'm not quite sure how to articulate appropriately what I am seeing, so I will give an example...
For instance...Each time I restart 1.5.5 and I go to the Files tab, the last drive/folder/file that I last worked with is highlighted. When I export a given result set, and then export another, the last drive/folder that I used is what is brought back into the export dialog box. In 2.1 I seem to have lost this function, and have to drill down each and every time I open, or do another export.
I have searched through the preferences, and can't really find anything that would seem to relate to this issue...
Had anyone else experienced this, and if so, have you been able to overcome it?
Thanks for any help....
Tim

The above is my problem at this moment, too . Will anybody help ... us ? ^^

All connections are lost in SQL Developer 1.5

Windows XP - SP2
Install Oracle Developer 1.5 today on my XP box. I don't have any old version of Oracle Developer installed before.
I created some connections and able to do some query against some database. Then, I close Oracle SQL Developer. When I relaunch it again, I found all the connections I have created are lost. When I try to recreate any connection, it failed and I see lots of java error by view "Logging Page - Log" tab. Not sure, how to copy and paste those log information.
Since I can't create any connections, I can't use SQL Developer 1.5 anymore. I have to reinstall it again.
Can anyone help?
Thanks!
Kevin

I have posted an announcement with the workaround for this problem, but I'll go ahead and duplicate them here :)
We have identified an issue with loading connections in SQL Developer 1.5. The symptoms of the problem are a failure to load previously defined connections in the Connections navigator coupled with errors displayed in the Logging Page related to severe problems initializing the JNDI context.
There are two known workarounds to this issue. The first is to install and use JDK 6.0 update 6 (or later). This may require removing the jdk directory from the SQL Developer install and/or editing the sqldeveloper.conf file to remove any references to a Java Home.
The second workaround is to modify the sqldeveloper.conf file to add some libraries to the classpath. These libraries are currently being added to the classpath by one or more extensions; however, adding them to the sqldeveloper.conf file will ensure they get added in the correct order. Add the following lines:
AddJavaLibFile ../../lib/java/api/jaxb-api.jar
AddJavaLibFile ../../lib/java/api/jsr173_api.jar
AddJavaLibFile ../../j2ee/home/lib/activation.jar
AddJavaLibFile ../../lib/java/shared/sun.jaxb/2.0/jaxb-xjc.jar
AddJavaLibFile ../../lib/java/shared/sun.jaxb/2.0/jaxb-impl.jar
AddJavaLibFile ../../lib/java/shared/sun.jaxb/2.0/jaxb1-impl.jar

Sql Developer Data Modeler all domains lost after changing to version 3.0

I have two questions:
1. Sql Developer Data Modeler - is it still a separate product? Or is it only available as integrated within Sql Developer?
2. After opening a model created with Data Modeler 2.0 with the new integrated Data Modeler 3.0 I lost all my domain definitions. What can I do to avoid this? Any help would be appreciated.
Thanks in advance
Holger

Hi Holger,
Sql Developer Data Modeler - is it still a separate product? Or is it only available as integrated within Sql Developer?Standalone version is here http://www.oracle.com/technetwork/developer-tools/datamodeler/overview/index.html
2. After opening a model created with Data Modeler 2.0 with the new integrated Data Modeler 3.0 I lost all my domain definitions. What can I do to avoid this? Any help would be appreciated.Copy file defaultdomains.xml from DM 2.0 installation to "sqldeveloper\sqldeveloper\extensions\oracle.datamodeler\types" directory (if you use version in SQL Developer) or to
"datamodeler\datamodeler\types" if you use standalone DM 3.0.
Location of this directory can be set in preferences - it's called system types directory there - it contains: default domains, RDBMS sites, logical types and custom scripts.

Prevent SQL Developer from writing to c:\documents and settings\

Hello,
does anybody know how I can change the directory where sql developer is writing to under windows?
Currently it is writing to c:\document and settings\... (my %APPDATA% path in windows).
I have quotas on my profile and the quotas are exceeded by SQLDeveloper.
Kind regards,
Marcus
Edited by: user12019413 on Feb 3, 2010 6:33 AM

If you want to change the directory where the SQLDeveloper configuration files are stored you can add:
AddVMOption -Dide.user.dir=DIRECTORY_YOU_LIKEto SQL_DEV_INSTALL_DIR/sqldeveloper/bin/sqldeveloper.conf

Need help with SQL developer settings

Hi Folks,
I am trying to access a schema via a user (with read-only privilages). What this means is that off the command line interface, I have to pre-qualify all my tables using the schema name. E.g. desc schema_name.table_1 etc.
When I connect to the schema via SQL developer, I do not see any tables. Are there any settings in the SQL developer that will automatically add the pre-qualifier before each table ?
BTW, I am using Oracle SQL Developer version 2.1.1.64 and my database is 10g.
Thanks in advance

The Tables node only lists your own tables. For others' objects, use the Other Users node.
Alternatively, you can assign synonyms to other users' objects to list them in your own tree.
Have fun,

SQL Developer 2.1 editor settings

In SQL Developer 2.1, when I single click on a pl/sql object in the navigation pane, a writable editor tab opens. How can I change this behavior so that it opens as read-only? I only want the pl/sql editor to be writable if explicitly selected. I could not find anything in the preferences for this.
Thanks, John

You can always make a suggestion on the SQL Developer Exchange, and/or vote on some of the existing read-only connection requests to add more weight for possible future implementation.

SQL Developer 1.51.5440 Font Settings

Hi,
In my other editors & dev tools, I set the font to Lucida Console 11. It looks OK. However, SQL Developer 1.51.5440 seems to interpret font seting differently:
- Lucida Console size 14 looks like size 10 in other editors.
- ClearType is not respected (look pixelated)
Also is it possible to set the font for the datagrid? (the one that display columns, constraints, data, etc. when clicking on a table).
Thanks in advance for any help.

Changing the font in the grid is currently only possible through Look&Feel themes.
Nevertheless, there's a feature request at http://apex.oracle.com/pls/otn/f?p=42626:39:482060356626746::NO::P39_ID:7001 (Raghu, a developer, promised to check the status).
The theme's fontsize can be changed in the IDE.Properties file (under your user profile). If you're lucky, your problem with the size in the other areas might be affected by this also.
As for Cleartype, I understand you need a JDK 1.6. Sqldev comes with a bundled 1.5, but you can download the latest non-beta and set its use in sqldeverloper.conf (under the installation folder):
SetJavaHome C:\Archivos de programa\Java\jdk1.6.0_07Hope that helps,

Top 10 Obstacles to Sql Developer Becoming a World-class Tool

I've been working with Sql Developer day and night for the last 6 months.
On a positive note, the SqlDeveloper team has been the most responsive Oracle product team I've worked with in the 19 years I've been working with Oracle tools. They pay attention to their customers. It's noticed and much appreciated!
I thought I would share the biggest problems that I face with the tool on a daily basis, the kind of problems that make me want to work with a different tool each and every day.
My intent isn't to gripe, it's to focus attention on the biggest productivity drains I face using the tool. Others may have a different list, based on their needs. Without further ado, here is my top 10 problems list:
1) Quality Control.
I cannot count on critical portions of the tool working correctly. This includes an oracle database development tool that is incapable of extracting oracle ddl correctly and which is incapable of correctly displaying information about SQL Server data and database objects. It also includes destroying connection files and losing keyboard settings. When the product was installed, it was incapable of properly displaying code in a worksheet when I scrolled thru the code. The details are listed in other postings of mine.
2) Quality Control.
See #1.
3) Quality Control.
See #1.
4) Very badly done threading.
The tool locks up on a constant basis when it does a many tasks. Rather than let me work on some other task, I have to wait for it to complete. My current work-around is to have two or three sql developer windows open. That sucks life out of my RAM supply, but at least I can get some work done. And, of course, it will often completely lock up and never return, which means I lose all unsaved worksheets. This forum is full of postings about these issues.
5) Memory Leaks / Internal memory corruption.
If I've had the tool open for a few days, or really worked it hard for a day, I will get bizarre compilation errors that make no sense. If I exit the tool, re-enter the tool, and compile the exact same code all will be well.
6) Awkward and slow data entry interface for frequently performed tasks.
Example: I create a new table and want to start defining columns for it. I remove my hands from the keyboard to press the + button, then I have to set focus on the column name field (it should do that for me!). Now that my hands are back on the keyboard, I have to backspace the dummy "column name" value in the column name field (it should ditch that dummy value for me). Only after all that can I actually enter a column name. When I want to add a new column, it's back to the mouse again, for the same drill. The down arrow key should take me to a new column record, as should pressing return at the end of the last field in the column row.
7) Destroys code
Changing a column datatype from varchar2 to nvarchar2 destroys the length of the column. Changing a field on a view destroys the instead of triggers. This is bad. There is no warning that this this is about to happen, which would at least give us a chance to avoid the problem. Better still, of course, would be not destroying that data.
8) Inaccurate checking for record locking.
When I try to edit records in a data grid for a table, I often get an error message telling me the data was modified in another session. It is simply not true. A hand-written update statement in a sql worksheet will work just fine. I've seen posts in the forum discussing this issue. An Oracle database development tool unable to reliably update oracle data tables is embarrassing. See Obstacle #1.
9) Unicode support
Sql Developer is heads above all the other tools I've tried out on this topic.
However, the configuration of the tool to provide unicode support needs to be simplified.
The tool needs to recognize the encoding of the files that are being opened up. On Windows Vista, Notepad seems to infallibly pick the right encoding for the file when I open it. Sql Developer should do the same. Files have specific encodings, the tool should have a default encoding (that I can override). Right now, the tool has a specific encoding and expects all files to match it. Extracting ddl to a worksheet does not respect the encoding choices of the tool, either. It only works with a limited set of tool encoding choices.
10) Resources
Does the sql developer team have the resources they need to compete with vendors like Microsoft? One really big reason for picking sqlserver over oracle is the ease of use of the Microsoft front-end tools. It's not until later that they may realize that Oracle has more capability, but that's still a lost sale.

We are acutely aware of quality and with each release work at improving this. Providing a polished, professional and ultimately user friendly and useful tool is our constant goal.
The broader our customer base grows, the more demands we have. This is a good and exciting position to be in, although it might mean that we need to slow down on our release cycles.
Release 2.0 should address more of the threading and memory leaks displayed as the team have rewritten some of the sections. As for resources, it's true we're a small team and we get on with the work that we do.It might be a little slower than some would like, but I'm not convinced that having large team is necessarily always the answer.
As ever, some of the points mentioned could be added to the Exchange. We'll be reviewing and updating the Exchange again in the New Year.
I think there is another point to add to your list. A lot of what the tool is and will become is from a positive customer interaction we have had to date. While we continue to grow this, I think the product will grow and improve. The forum and all the positive interactions that happen here are key to taking the product forward.
Regards
Sue
