SQL/Developer & Resource Usage.

A quick comparison with Toad on XP.
Both software connected to same database running a blank sql window.
Toad = 30MB
SQL/Developer =60MB
Usage of SQL/Developer see memory usage rocket to 180MB.
Shutdown of SQL/Developer closes down the process but the PC still runs slow and requires a reboot.
Nice product but what's the deal guys ?

It's the insight stuff.
You shold turn off sql insight as documented here: http://www.oracle.com/technology/products/database/project_raptor/ea6_relnotes.html.
<snip>
We now have a command line way to turn off code insight. This is very useful for users who access larger databases. To disable Code insight, startup SQL Developer from the command line using:
On Windows: sqldeveloper -J-Dsdev.insight=false
On Linux or Mac: Run sh sqldeveloper -J-Dsdev.insight=false
or edit sqldeveloper.conf and add "AddVMOption -J-Dsdev.insight=false".

SQL Developer - Memory Usage

We have SQL Developer installed on our Citrix farm and we are facing hard times right now. Unfortunately SQL Developer is consuming in some cases more than 650 MB/session. And since we have on each site more than 50 users in same time, server gets exceeded very fast. Currently server is running Windows 2003 R2 edition x86. We know that this is bad and we are planning on switching on Windows Server 2008 R2. And here comes my questions:
Will Windows Server 2008 R2 work more effectively with Java x64 and SQL Developer x64 and resolve our memory issues?
Thank you.

Hi,
I have no idea if Windows Server 2008 runs Java applications better than 2003 but, regardless of which you run, here are a couple of ideas that may be of help:
1. x32 Java/SQL Developer starts up with a smaller working set (246,000 KB) than x64 Java/SQL Developer (318,000 KB).
2. Try tweaking the garbage collection algorithm, using Garbage-First:
Re: Memory Leak or Bad Java Garbage Collector
I ran across this (old) comment from a blog on blogs.msdn.com:
Even though Windows Server 2008 R2 is exclusively a 64-bit operating system, 32-bit applications are
supported by enabling the WoW64 optional feature. If this feature is not enabled and you try to run a
32-bit application, the application will fail to execute. The WoW64 execution layer is an optional component
that is installed by default on R2 releases after beta1. You can save resources by removing the feature if
you are not going to be running 32-bit applications on your Server Core install. Regards,

SQL Developer - High usage of memory !

Hello All,
I have downloaded SQL Developer 4 today and when i started working on it, my computer memory started to IRK a lot. So when i checked in "Task Manager", i found something very strange.
The memory consumption was too high (almost 350 MB). Can someone tell me why is this version of SQL Developer is using such as huge amount of memory or is there some workaround for this issue.
I tried to attach the screenshot but that did not happen.
Any help is greatly appreciated.
Thanks in advance,
Aravind S

Why is that number, 'too much?'
What Windows reports is rarely accurate with Java applications.
How much RAM do you have on your machine, and how much was free when your machine started to misbehave?

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.

SQL Developer occasionally hogs all CPU resources

Client OS: Windows XP Professional
Connecting to : Oracle 9.2.0.3 on Sun Solaris server
I encountered a few instances where SQL Developer hogs all CPU resources on my Windows XP notebook.
I usually have to kill the SQL Developer process.
I have noticed this happening occasionally when I :
1. hit Enter at the SQL Worksheet window
2. hit F9 at the SQL Worksheet window - the query does not start
How do I collect a dump or some kind of debug information when the above happens ?
Who can I send the information to ?

How do I collect a dump or some kind of debug
information when the above happens ?Start SQLDeveloper using sqldeveloper.exe in <sqldeveloper>\jdev\bin
When sqldeveloper starts hogging cpu, go to the console window and type ctrl-break. You should get a thread dump.
Who can I send the information to ?If you have a support contract, you can raise a TAR, otherwise post the thread dump here.

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

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.

SQL Developer usage problem

Hi All
I have installed sql developer V 4.1 to my computer and all the necessary java apllications have been installed. When i opened the program menu screens can only be shown when i get my cursor over it as shown in the below. İ have format my OS system because i think this can be because of my region and registy settings. So at the final i have a fresh Windows 8.1 Eng X64 Ent edition. and up to dated java version but same problem.
Please give an opinion to me
Thanks.

Hi Jeff,
I would like add some input:
I have similar issue, but in different case.
SQL Developer installed on real Win7 machine (no virtual) and uses the appropriate jdk (latest in each case: 7 for v4.1 EA1 and 8 for v4.1.EA2).
It works fine and correct on the desktop, but when I try to continue my task over Remote Desktop its behavior is like as the described one.
And I have feeling that happens during switches from v3.x to v4.x (sorry don't remember exactly).
Hope it helps in your investigation.
Best Regards

SQL Developer usage (newbie) question - using for script development

I'm new to Oracle, but not to SQL (used MS SQL Server off and on for 3 years prior). SQLDeveloper (v1.5.1) was recommended as a dev tool for the work that I'm doing in in Oracle 10.2.0.4. I'm looking to write some scripts to eventually become stored procedures. The problem I'm having is it seems i can only execute one line even though there are multiple statements in the "Enter SQL Statement" window pane.
ie.
select id, Full_Name, unique_name, user_id from srm_resources;
select id, user_name, last_name, first_name from cmn_sec_users;
when i highlight those two lines and click the "Excecute Statement" button, only the top line generates results.
I'm used to using MS SQL's Query Analyzer where I could select one statement or multiple statements to execute, even non-SELECT statements (variable assignments, math, control loops). It does not appear that I have this kind of functionality in SQL Developer - or an I not using the tool correctly?
Thanks
Brian

I'm assuming you're meaning the SQL worksheet here. The green arrow icon is execute statement (F9) The tiny green arrow is execute script (F5). I'm currently on 1.5.4 of SQL Developer.
Hope this helps some. I would download the documentation also.

SQL Developer 3.2.09 and excess memory usage

This is really something that will ultimately end up as a bug-fix request, I'm thinking, but I was wondering if anyone else is seeing the same thing, before I report it.
We're using SQL Developer 3.2.09 in a Citrix environment, and we're finding that it's using up an inordinate amount of memory, causing performance problems for anyone else with applications open on the server. We haven't seen any patterns so far ... like if it's a side-effect of having the tool open for long periods of time (memory leak), or if certain activities within the tool are prone to using up too much memory.
Has anyone else experienced the same thing when running SQL Developer on their desktop, or in Citrix? And have you been able to tune it at all?
Thanks,
--=Chuck

SQL Developer is java based and relies on the jvm's memory management.
I'm not aware of any memory leaks as such, but memory tends not to be returned to the system.
Queries which return large return sets tend to use a lot of memory (SQL Developer has to build a java table containing all the results for display).
You can restrict the maximum memory allocated by modifying settings in in <sqldeveloper>\ide\bin\ide.conf
The defaults are -
AddVMOption -Xmx640M
AddVMOption -Xms128M

SQL Developer High Memory Consumption 3.2.20.09.87

Hello,
I have been using SQL developer for quite some time and had initially had problems in the past with high memory consuption when I use this tool.
I have received and applied advice from this forum and while it had helped a little, the majority of the high memory consuption remained an issue.
I finally got more time to dig around and try to specifically isolate where the problem seems to be coming from and here is what I found.
*1)* I have removed the Check for Updates feature
*2)* I have turned off many of the extensions except for DBA Navigator, Real Time SQL Monitoring, SearchBar and Snippet.
*3)* When I start a fresh SQL Developer Session and initiate a Oracle Connection the application consumes roughly 148 meg fo RAM
*4)* When I open my Windows Task Manager and watch the memory allocated to SQL Developer I notice it goes up when I move my mouse over the SQL Developer tool and When I run through menus at roughly 5k a second or so and the memory is never released back to the system.
*5)* When I run a Large SQL to the grid the memory jumps by about 100 meg or so and will continue to do so every time I repeat the SQL until SQL Developer consumes roughly 748 meg of RAM.
*6)* 748 Meg of RAM seems to be the number when SQL Developer (with one Oracle connection) no longer continues to consume more and then not return the memory to the system.
Is there a way to have SQL Developer automatically clear up it's active memory usage without closing it down and restarting it?
Why does SQL Developer continue to consume more and more memory just from moving your mouse over it and/or by navigating menus?

Aces!!! You nailed it Gary...
Thank you.
I applied fixed noted in Re: Reduce SQLDeveloper memory footprint with JDK 1.7

comment the following two lines as shown below
#AddVMOption -Xmx640M

Now SQL Developer runs at roughly 500 meg.
I guess the only thing I have left to ask others reviewing this would be if there is a way to get these memory values down without having much adverse impacts on SQL Developer based on newer JVM switches/functionalities.
The posts that drove these changes are old from a technologoical perspective :) 2010.

Password change fails in SQL Developer with verify function...

A couple of months ago I enforced a password verify function on our 11.2.0.3 databases and also one legacy 10.2.0.4 database.
At the time I tested on my account (which had elevated privileges...doh!).   Now some users are hitting expiry, they can't change it via SQL Developer.
If I create a user with 'create session' privilege and set their profile to one that uses the verify function (see both below), I then log in to SQL Developer (we have tried with versions 3.1 (Windows) and 3.2 (Linux) with same failure results.
BTW,.. the password verify function enforces the following:
password must be minimum of 8 characters
password must not be the same as the user name, or user name (1-100)
password must contain at least a single digit
password must contain at least a single character
1. Works = I log into the local server and run command line SQLPlus, type 'password' and update.   I can successfully change my password.
2. Fails = I log into the local server and run command line SQLPlus, type 'alter user <me> identified by <newpwd>;' I get:
TEST: SUTEMP > alter user sutemp identified by carport9999;
alter user sutemp identified by carport9999
ERROR at line 1:
ORA-28221: REPLACE not specified
This error is because the account does not have the 'alter user' privilege.   I'm okay with this, as I don't want our users having this privilege.
3. I start SQL Developer 3.2, type 'alter user <me> identified by <newpwd>;' I get the same ORA-28221 error as above.   That is fine, and as expected.
4. Now in SQL Developer, I type 'password', set a valid password, but I get 'Failed to change password' in the Script Output tab.
I have a database 'after servererror on database' trigger set, and querying the database table it is logging into, I see a record with a date stamp matching my failure with a server_error=28221 (the same as above).
So I'm wondering if I'm doing something wrong here, or if this is a bug in SQL Developer.   I don't want standard users having 'alter user' privileges, but I do want to enforce password verification.
I get the same result on three 11.2.0.3 databases (haven't tried any more but suspect same results for others) and one legacy 10.2.0.4 database, and using SQL Developer 3.1 and 3.2.

okay,... I just saw another website which shows I should put in the 'replace <oldpwd>' clause in.
This works in SQL Developer:     alter user sutemp identified by carport999 replace garage999;
So why does the 'password' command fail?     (Developers: it would also be helpful to have the ORA- error displayed as opposed to 'Failed to change password')

PI 7.11 - SXI_CACHE Issue - SQL 0904 - Resource Limit Exceeded

Hi PI & IBM I Gurus,
We are having the SXI_CACHE issue in our PI 7.11 SPS04 system. When we try to do the delta cache refresh through SXI_CACHE, it is returning the error SQL 0904 - Resource limit exceeded. When we try to do the full cache refresh, it is getting the issue 'Application issue during request processing'.
We have cleaned up the SQL Packages with DLTR3PKG command, which did not resolve the issue. We recently performed a system copy to build the QA instance and I observed that the adapter engine cache for the development is presented in the QA instance and removed that cache from there.
I am not seeing the adapter engine connection data cache in our PI system. The adapter engine cache is working fine.
All the caches are working fine from the PI Administration page. The cache connectivity test is failing with the same error as I mentioned for the SXI_CACHE.
Please let me know if you have encountered any issue like this on IBM I 6.1 Platform.
Your help is highly appreciated.
Thanks
Kalyan

Hi Kalyan,
SQL0904 has different reason codes ...
Which one are you seeing ?
Is the SQL pack really at its boundary of 1GB ?
... otherwise, it is perhaps a totally different issue ... then DLTR3PKG cannot help at all ...
If you should see this big SQL Package, you should use PRTSQLINF in order to see if there is more or less over and over the same SQL in, just with different host variables or so ...
If the last point should be the case, I would open a message with BC-DB-DB4 so that they can check how to help here or to talk to the application people to behave a bit different ...

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.

Sue

Apex Listener 2.0.1 vs Sql Developer Administration 3.2.20.09 bugs

Apex Listener 2.0.1 / Sql Developer 3.2.20.09 / Apex 4.1.1
1. I'm using basic connection type with service name. Each time I connect to listener administration it is resetted to SID with default name as orcl.
2. Test Settings does not work in case hostname is localhost.
Database Settings apex:Cannot connect to APEX_PUBLIC_USER. Исключение ввода/вывода (input/output exception): The Network Adapter could not establish the connection>
At the same time it's working in defaults.xml:
<entry key="db.hostname">localhost</entry>I'm not sure why. Database and Apex Listener are installed on the same mashine. May be this can help:
<Warning> <Server> <x> <> <DynamicListenThread[Default]> <<WLS Kernel>> <> <> <> <BEA-002611> <Hostname "x", maps to multiple IP addresses: 10.110.x.x, 0:0:0:0:0:0:0:1> 3. I can see "Enable RESTful Services" action in (url http://docs.oracle.com/cd/E35137_01/appdev.32/e35117/intro.htm#autoId110)SQL Developer User's Guide. Still there is no such action in Sql Developer. Thus settings are always uploaded with enabled RESTful Services.
I see error
The pool named: apex_al does not existeach time I connect to Apex Listener Administration in case of RESTful Services is not configured during configuration of apex.war.
I can't find any restrictions for RESTful Services to be configured. So I think this error is unnecessary.
4. From sql developer User's Guide
Connect (context menu only): Connects to the Application Express Listener (see Connecting to Application Express Listener Server).Retrieve Settings, Upload Settings, and Launch URL are enabled when you connect to the Application Express Listener.>
administration settings are retrieved and displayed but still Retrieve Settings, Upload Settings, and Launch URL are disabled in context menu after connection.
I need to perform New Administration action to make them enabled.
Is this expected behavior ?
Is this all bugs or known features ?

Igor

SQL Developer and Blocking View of Other Users' Objects

I am using SQL Developer in a classroom environment. My student users can “see” Other Users objects. They cannot modify, but none the less can see the structure and data.
I only want the users to be able to see their own objects. Is there a privilege that needs to be revoked? (In using SQL Plus command line, this was not a problem.)
Thanks.
-Karen

Karen,
From sysdba account (sys/system). Run following and verify for that particular user grant is revoked. May be exit from sql developer and log back in or refresh view.
YOu can also potenially revoke all the privs from all non admin uses i.e.r even connect/resource roles and grant them back.
revoke select any table from yourschemaname;
revoke connect from schemaname;
revoke create session from schemaname;
revoke resource from schemaname;
Then just grant privs as need basis
grant connect to schemanme;
grant resource to schemaname;
