Double the memory usage in SQL Developer 1.5 vs 1.2.1

I have observed that SQL Developer 1.5 uses at least twice the amount of RAM than 1.2.1 when performing the same functions. This seems rather inefficient. I am merely opening the application and opening a single connection, where 1.2.1 uses ~60MB RAM, while 1.5 uses ~110 - 150MB ram. Is something wrong here, or is the enhancing of the GUI in 1.5 just using up mad RAM? Can this be cleaned up somehow? Thanks.

I agree I have noticed 1.5 is very taxing on my machine.
1.51 5440
XP 1 GB RAM
According to Task Manager, Mem Usage is 6.5 mb, and VM is 240 meg, this is one database connection and editing one function.
I know memory issues were brought up in other versions but it seems it is getting worse not better. I wish Oracle would acknowledge the issue.

Memory used by SQL Developer

Hello
I was running a query with output of around 9 lakh records. I did this with Toad earlier and now I tried with SQL Developer.
I found a difference like this.
When in toad the records were being fetched the memory used by Toad was not getting increased as shown in the Task manager processes. While the PF Usage was getting increased which I understand is SWAP file. When all the rows were received this increase was approximately same as the file I created after exporting that data.
In case of SQL Developer the memory used by SQL developer itself goes on increasing.
Will this have impact on machines actual RAM being used ?
or In other words is Toad using swap memory directly rather than consuming RAM for saving file output ?
Regards
Sanjeev

I believe the difference could be that toad fetches each record and automatically flushes it to the output file while SQL Developer might keep all the records in memory or use a different file handling method. Basically what you said sounds as a reasonable assumption.

When i run exe built in Labview 7.1 the memory usage goes on increasing

Dear Sir/Madam
I have built an application in LabView 7.1. When i run this application and view the memory usage in Task manager, i find that the memory usage goes on increasing.
Please help.
With Regards
Ravindra Kumbhar

Hi, Ravindra,
It looks that you have memory leak in your application.
There are lot of possible reasons for memory leaks - opened in cycle and not closed references, continuosly growing arrays, memory allocation in own DLLs, etc.
Normally you should have the same behaviour in development environment as well (memory of LabVIEW.exe incresed continuously).
You should check the code, which executed repeatable (while/for loops) for allocated, but not closed resources. What you can do is following - remove (or isolate) parts of you code, executed in cycles, then check is leak present or not. So, step by step you will found the place where leak occurred.
best regards,
Andrey.

Where to find the blob viewer in sql developer

Hi,
i tried to find the blob viewer in sql developer to see blob column data , but failed. The manual introduce blob vievers but not mention where it is in sql developer
can any gurus guide me to find blob viewers

It shows the raw binary data unless it is a JPEG, GIF or PNG where you can see a picture.

Please make the memory usage built-up a top priority to problemsolve.

Hi, Firefox is my favorite browser on OSX) , but the memory usage is really getting annoying. It's been 2 yrs and I have to restart Firefox every couple of hours to keep the memory usage in check. If i don't do that
I think this is a serious issue with your browser. None of the other browsers (Safari, Chrome)I use have this problem, however they're not that user-friendly in my opinion.
Like I said it has been 2 yrs and the forums are filled with this topic, without any real solutions, are there actually people on this problem? It's a pretty big problem, and honestly I don't understand why there's no correspondence from Firefox, that they acknowledge the problem and they're working on it or something.
Before those 2 yrs, never a hitch. The problem must've been introduced since FF21 or 22, not sure.
I'm experiencing exactly the same as "Cyberpawz":
https://support.mozilla.org/en-US/questions/958108?page=6
I'm a avid Firefox user and just want the voices of the users experiencing this problem to be heard. And ofcourse the problem to be resolved.
Thanks for listening!

The memory issues will be real problems, just look at the viewing stats on the thread you linked to
'' 104 replies, 94 have this problem, 7788 views ''
The easy problems will have been identified and fixed. The difficult or least common ones need users able to help troubleshoot and most just want to complain not file bugs, (Please note such bugs will likely only be followed up if it is a Firefox bug or a problem with a single popular addon).
If you follow the advice from ''Cor-el'' and try with a new profile with all plugins disabled you should find the problem goes away.

Viewing the database version in SQL Developer

Hello there,
I am using SQL Developer version 1.5.0.53, and I was wondering if there is a way that I can view the database version within SQL Developer?
I know when you log on in SQL *Plus it shows it, is there anywhere in SQL Developer that it can be viewed?
Thanks,
ivalum21

There is a report.
Data Dictionary Reports -> About Your database -> Version Banner
but it is probably just quicker to select * from v$version;

How to integrate the Data modeler in Sql developer

Hi
How can we integrate the data modeler into sql developer and use the data modeler?
Thanks

Integrating different oracle products (SQL Developer [Data Modeller], JDeveloper, ...) on platforms like Eclipse, Netbeans, JDeveloper Framework is a really missing feature.
JDeveloper has a good approach for integrated Java and database development, but has not immediate benefits from from other development streams like SQL Developer.
On daily work we must use more than three different tools for most common task
- editing stored functions, procedures and packages with SQL-Developer (code formatter in Jdeveloper produces sometimes UNREADABLE code ( So we are using TOAD instead ). Why can't Jdeveloper use SQL-Developer formatting tools in bug fixed verrions from 1.5.5?
- database modelling with SQL Developer Data Modeler without PLSQL package support ???
- database development with JDeveloper, ADF and offline database model without capabilities for logical databse models
Please put them all together!

When I take a photo it goes to camera roll and my photo stream. This doubles the memory being used. Can I delete the camera roll?

When I take a photo it goes to camera roll and my photo stream. This doubles the memory being used. Can I delete the camera roll? This seems pointless to have the same pictures twice. My Photo Stream pictures upload to my PC, so why should I have the same photos in Camera Roll?
Am I supposed to delete pictures in camera roll after they go into My Photo Stream? Why can't I just take a picture and it go to photo stream on its own? My camera roll AND My Photo Stream go back to March 11, 2014

You're misinformed and have asked several questions that I'll try to tackle.
No it doesn't double the memory. The Photo Stream image is simply a pointer to what you have in your camera roll.
If you delete pictures from your camera roll, leaving them only in Photo Stream, you will lose those images forever if you don't then pull them out of Photo Stream on another connected device. Photo Stream is meant to be TEMPORARY cloud storage for your images. Read about it here: iCloud: My Photo Stream FAQ
You should ALWAYS offload your images if you want to keep them. See how to do that here: iOS: Import personal photos and videos from iOS devices to your computer

Want commands running in the back ground in sql developer

HI all,
I am new user to oracle sql developer. i started using it and found interseting. It is very easy just using the GUI interfaces. what ever i need to do i can do using the GUI interfaces instead of using commnads. makes my work easier. BUt there starts my concern
if i continue to use the tools one day i will not know the commands which are executed actually.
Is there any way throught which i can look what every that commands or queries that are executed in the back ground for my instruction in the foreground

Hi,
If you truly wish to see all the SQL and PL/SQL executed for a given connection, you can try the following:
1. Tools -> Monitor Sessions...
2. Select a connection for a user with appropriate privileges (e.g., must be able to run DBMS_MONITOR)
3. In the list of sessions, right-click on a session of interest, select Trace Session and click Apply
4. After completing the desired activity on the connection of interest, close the connection.
5. Open the trace file in SQL Developer (File -> Open, or drag and drop it) -- make sure the Filter drop-down is set to All -- to see the SQL.
6. Pick one of the four tabbed views of the trace file data: List, Tree, Statistics, History
Step 5 is easy if the DB is local. For example, with Oracle 10g Xe on Windows, look for the most recent trc file in a directory like
C:\oraclexe\app\oracle\admin\XE\udumpFor a remote DB you would need to copy the trc onto a shared network drive or ftp it to your local machine.
If you just wish to see DDL commands as you manipulate DB object definitions from the Connection Navigator tree or the Object Viewer Actions list, the UI usually provides a SQL tab so that you may view the SQL before clicking the Apply button.
Hope this helps,
Gary

Double quote encapsulated identifiers in sql developer 1.5.1

hello,
i migrated a mysql database to oracle using the sql developer 1.5.1 on linux. unfortunately i'm using some reserved words in my table name / columns. how is it possible to generate an import script that uses double quote encapsulated identifiers? in the migration workbench, there is an option named "Create ANSI-compilant names" which should do what i need, but i cannot find this option in sql developer.
thank you for your help. regards,
sebastian

I'm not sure what your question is; Did you migrate successfully? How do you generate an import script? What is failing? Can you provide an example?

Why does the query work in SQL Developer, but not in APEX?

Hi, guys:
I have a silly question. I have a complicated query, and I tested it successfully with SQL developer, and result is correct. However, when I put it into APEX to generate a report, it always reports no data found. I also know the condition related to "other marks" select list in the where clause part causes this problem. It also looks strange: before I add this condition, everything works OK; after I add this condition, even I do not choose the "other marks" select list, other components do not work neither. I always got no data found result. Could anyone help me on this problem? You can also visit our developing site as http://lsg-solutions.com:8888/apex/f?p=206 to check the problem.
Thanks a lot

My suggestion would be to put some instrumentation into your query and see what values you are using.. Or even simpler take out ALL the where clauses you can until data starts to sho wup and then add them back in one at a time until you find the culprit..
My bet would be on any date comparisons you are doing between page items and database columns..
Thank you,

Customising the Legend (Legend Box) - SQL DEVELOPER DATA MODELER

Hi,
Is there a way to customize the legend Box (obtained when you right click Show->Legend in the Relational or Logical model window) in the latest latest version of SQL Developer Data Modeler.
For example i would like to remove a particular attribute from the legend say Changed by or Author.
Thanks in advance.

Hi,
It is not possible.
There will be such option in the future.

Domains usage in SQL Developer data MODELER

Hi,
I'm trying to understand how to use Domains in Oracle SQL Developer Data Modeler. We use version 3.1.3 . before I used Toad Modeler where domains are just part of your main design.
Oracle data modeler has some different concept.
let's assume I'm working on 2 designs: DesignA and DesignB that include relational models.
DesignA and Design B should use domains but list of domains in design A is very different than in design B.
Default domain file is located on c: drive where SqlModeler is installed. It is obviously unacceptable , so I need to change Default System Type directory in preferences.
And of course I want to have different domain directories for DESIGN A and DESIGN B.
So when I open design A then I changed Default System Type directory let's say to x:\AAA. Then i close design A and open Design B and change Default System Type directory to x:\BBB
I checked folders AAA and BBB and they have necessary XML files there: defaultdomains.xml, defaultRFDBSSites and so on....
Now questions:
can I rename defaultdomains.xls to something else like AAAdomains.xls? Domain administration can edit any domain file with any name , but how can I associate certain domain file with my design? My wish , when I open my design , then corresponding domain file will be open automatically. Is it possible?
If I open 2 designs in Sql Modeler and switch between designs then corresponding domain files should be changed automatically as well. Currently I shouldn't forget to change default System Type directory every time when I switch models. Is it the only way to handle it?
Thanks
vitaliy

Hi Vitaliy,
We use version 3.1.3
I recommend always to use the latest version. If you don't want to use beta (DM 4.0 EA is out) you can use DM 3.3.
Otherwise Oracle SQL Developer Data Modeler supports two types of domains:
1) DM installation domains - those in file defaultdomains.xml
2) Design level domains - they are stored in design directories and are visible to particular design only. They can be created in following ways:
2.1 Manually - there is a property "Domains file" and you id it's not set "defaultdomains" domain will become design level domain and will be stored in file with provided name (without .xml extension)
You can change later the file for design level domains, however you cannot change file for domain already in defaultdomains.xml.
2.2 Using types to domains wizard you can generate design level domains
2.3 Design level domains are created during import of DDL files (controlled in preferences)
2.4 You can import domains from specific file with domains using "File>Import>Domains" - you need to rename the source file if it's named defaultdomains.xml otherwise you'll get domains as installation domains
If the list with domains is too long you can define a list with preferred domains (or/and logical types) in "Preferences>Data Modeler>Model" and you can use shorter list in Table/Entity dialog if check "Preferred" check box next to "Type:" combo box.
If I open 2 designs in Sql Modeler and switch between designs then corresponding domain files should be changed automatically as well
If you open 2 designs in one instance of DM they will use the same file with default domains i.e. you'll lose domains in one of design depending of setting for "system data type directory". You need to go with design level domains.

Edit the results list in sql developer 1.5

Hi
is there someone that know if it is possible to make a querry in sql developer and then edit in the results list?
I have tryed but can not se how.

Getting the schema using Oracle SQL Developer 1.5.1

I need to generate a report in CSV/XLS format using Oracle SQL Developer 1.5.1 to get the schema details
in the below format.
Table Name: XXXXXXXXX
Table Space Name: XXXXXXXXXXXXXXX
Structure :
Field Name Data Type Size
Xxxxxxxx xxxxxx xxxxx
Xxxxxxxx xxxxxx xxxxx
Xxxxxxxx xxxxxx xxxxx
Xxxxxxxx xxxxxx xxxxx
Field level constraint:
Xxxxxxxxxxxxxxxxxx
Table Level Constraint:
Xxxxxxxxxxxxxxxxxx
Indexes:
Index Name Column Name(s) Table space name
Xxxxxxxx xxxxxxxxx xxxxxxxxxxxx
Xxxxxxxx xxxxxxxxx xxxxxxxxxxxx
Xxxxxxxx xxxxxxxxx xxxxxxxxxxxx
Sequence Number:
Xxxxxxxxxxxxxxxx
Triggers:
Xxxxxxxxxxxxxxxxxx
I am using a query to do that, but I cannot run more than one queries in the Create Report Dialog.
I went to the Menu->View->Reports. In that, I chose User Defined Reports, created a new folder called Schema Detail and in that a report named Schema Detail. I right click on that report, choose Edit option, Create Report Dialog opens.
In the Create Report Dialog, I chose the option Script for Value of Style.
In the SQL column I enter a query "select * from table_names". But, if I enter another query after that, it does not run and reports an error "SQL Error: ORA-00933: SQL command not properly ended
00933. 00000 - SQL command not properly ended" Cause: Action: "
I end the first query with a semi colon, but it does not work.
The queries run fine in a SQL Worksheet. There, I can terminate the first query with a semi colon and enter the second query. Then, I run both of them together so that result-set of second query appears after the second.
Am I doing something wrong? Can someone please advise on how to get the information I need?
Thanks a lot.

You can do it in SQL Worksheet because you are running a script. You could run the script in SQL*Plus, and even start it from a bat/cmd file.
Or if you want this as a User Defined Report, you might make it a PL/SQL style report. Here, all output is done through DBMS_OUTPUT.PUT or DBMS_OUTPUT.PUT_LINE. You can output HTML tags or plain text. I have an example in my paper for ODTUG Kaleidoscope 2009.
