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?
Here is my About Detail;

Aces!!! You nailed it Gary...
Thank you.
I applied fixed noted in Re: Reduce SQLDeveloper memory footprint with JDK 1.7
For others, to summarize my changes.
product\11.2.0\client_3\sqldeveloper\sqldeveloper\bin\sqldeveloper.conf
AddVMOption -XX:+UnlockExperimentalVMOptions
AddVMOption -XX:+UseG1GC
AddVMOption -XX:MaxGCPauseMillis=50
AddVMOption -XX:GCPauseIntervalMillis=200
AddVMOption -XX:MaxPermSize=128M
AddVMOption -Xms50M
AddVMOption -Xmx384M
AddVMOption -XX:MinHeapFreeRatio=10
AddVMOption -XX:MaxHeapFreeRatio=10
product\11.2.0\client_3\sqldeveloper\ide\bin\ide.conf
comment the following two lines as shown below
#AddVMOption -Xmx640M
#AddVMOption -Xms128M
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.

High memory consumption in XSL transformations (XSLT)
Hello colleagues!
We have the problem of a very high memory consumption when transforming XML
files with CALL TRANSFORMATION.
Code example:
CALL TRANSFORMATION /ipro/wml_translate_cls_ilfo
SOURCE XML lx_clause_text
RESULT XML lx_temp.
lx_clause_text is a WordML xstring (i.e. it is a Microsoft Word file in XML
format) and can therefore not be easily splitted into several parts.
Unfortunately this string can get very huge (e.g. 50MB). The problem is that
it seems that CALL TRANSFORMATION allocates memory for the source and result
xstrings but doesn't free them after the transformation.
So in this example this would mean that the transformation allocates ~100MB
memory (50MB for source, ~50MB for result) and doesn't free it. Multiply
this with a couple of transformations and a good amount of users and you see
we get in trouble.
I found this note regarding the problem: 1081257
But we couldn't figure out how this problem could be solved in our case. The
note proposes to "use several short-running programs". What is meant with
this? By the way, our application is done with Web Dynpro for ABAP.
Thank you very much!
With best regards,
Mario DüsselHi,
q1. how come the Ram consumption is increased to 99% on all the three boxes?If we continue with the theory that network connectivity was lost between the hosts, the Coherence servers on the local hosts would form their own clusters. Prior to the "split", each cache server would hold 1/12 of the primary and 1/12 of the backup (assuming you have one backup). Since Coherence avoids selecting a backup on the same host as the primary when possible, the 4 servers on each host would hold 2/3 of the cache. After the spit, each server would hold 1/6 of the primary and 1/6 of the backup, i.e., twice the memory it previously consumed for the cache. It is also possible that a substantial portion of the missing 1/3 of the cache may be restored from the near caches, in which case, each server would then hold 1/4 of the primary and 1/4 of the backup, i.e., thrice the memory it previously consumed for the cache.
q2: where is the cache data stored in the coherence servers?on which memory?The cache data is typically stored in the jvm's heap memory area.
Have you reviewed the logs?

Environment:
MAC OSX 10.9.5
Firefox 32.0.3
Firefox keeps consuming lot of memory when you keep refreshing a tab after an interval.
I opened a single tab in my firefox and logged into my gmail account on that. At this stage the memory consumption was about 400MB. I refreshed the page after 10 seconds and it went to 580MB. Again i refreshed after 10 seconds and this time it was 690MB. Finally, when i refreshed 3rd time after 10 seconds, it was showing as 800MB.
Nothing was changed on the page (no new email, chat conversation, etc. nothing). Some how i feel that the firefox is not doing a good job at garbage collection. I tested this use case with lot of other applications and websites and got the similar result. Other browsers like Google chrome, safari, etc. they just work fine.
For one on of my application with three tabs open, the firefox literally crashed after the high memory consumption (around 2GB).
Can someone tell me if this is a known issue in firefox? and is firefox planning to fix it? Right now, is there any workaround or fix for this?Hi FredMcD,
Thanks for the reply. Unfortunately, i don't see any crash reports in about:crashes. I am trying to reproduce the issue which will make browser to crash but somehow its not happening anymore but the browser gets stuck at a point. Here is what i am doing:
- 3 tabs are open with same page of my application. The page has several panels which has charts and the javascript libraries used for this page are backbone.js, underscore.js, require.js, highcharts.js
- The page automatically reloads after every 30 seconds
- After the first loading of there three tabs, the memory consumption is 600MB. But after 5 minutes, the memory consumption goes to 1.6GB and stays at this rate.
- After sometime, the page wont load completely for any of the tabs. At this stage the browser becomes very slow and i have to either hard refresh the tabs or restart the browser. -
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 SWhy is that number, 'too much?'

Very high memory consumption of B1i and cockpit widgets
Hi all,
finally I have managed it to install B1i successfully, but I think something is wrong though.
Memory consumption in my test environment (Win2003, 1024 MB RAM), while no other applications and no SAP addons are started:
tomcat5.exe 305 MB
SAP B1 client 315 MB
SAP B1DIProxy.exe 115 MB
sqlservr.exe 40 MB
SAPB1iEventSender.exe 15 MB
others less than 6 MB and almost only system based processes...
For each widget I open (3 default widgets, one on each standard cockpit), the tomcat grows bigger and leaves less for the sql server, which has to fetch all the data (several seconds on 100% of CPU usage).
Is this heavy memory consumption normal? What happens if several users are logged into SAP B1 using widgets?
Thanks in advance
Regards
SebastianHi Gordon,
so this is normal? Then I guess the dashboards are not suitable for many customers, especially for them who are working on a terminal server infrastructure. Even if the tomcat server has this memory consumption only on the SAP server, when each client needs about 300 MB (and add some hundred for the several addons they need!), I could not activate the widgets. And generally SAP B1 is not the only application running at the customers site. Suggesting to buy more memory for some Xcelsius dashboards won't convince the customer.
I hope that this feature will be improved in the future, otherwise the cockpit is just an extension of the old user menu (except for the brilliant quickfinder on top of the screen).
Regards

MAIL Version 7.2 (1874) High Memory Consumption
My MacBook Air has lately increased its Memory consumption ( It has 4 GB Ram ) up to the point that is getting very slow operationally speaking. Is there something that I can do to improve it, controlled it.
Have you installed anything recently? Open up Activity Monitor and check what applications are running and see what's consuming the most resources.

Workstation Manager Service - High Memory Consumption
Anytime I leave my work PC running for 2-3 days without restarting it, the Workstation Manager Service gradually starts to consume more and more memory. It seems like every day past when I restart this work PC, the Window's Task Manager will show that the WM.EXE process is consuming 100 MB more memory than it was the previous day. For example, my PC hasn't been restarted in about 3 days now, and the Task Manager is showing that the WM.EXE process is using 382,940 K of memory. If I were to not restart this PC for another 2 days, it would then be consuming more than 500,000 K of memory. None of the other processes running on this PC seem to be exibiting this weird behavior if I don't restart the PC. The version number is 6.5.0.4.
I've attached a zip file containing 3 screenshots (spanning over 2 months) of the Window's Task Manager showing what I am referring to.
Does anyone know what may be causing the WM.EXE process to behave like this and how I can go about resolving this issue?Make sure you are at SP2 IR1.
I don't recall that version number.
However, there were some known leaks at one point in time there were
addressed.
Its just been too long for me to recall the details.

SQL Developer 3.0/3.1 64 Bit Memory Setting
Hi,
To avoid hitting memory setting issues with SQL Dev 3.0/3.1 64 bit clients, you can make the following changes:
1) Close SQL Developer
2) Locate the sqldeveloper.conf file
Found in directory:
C:\<SQLDeveloper32\sqldeveloper\sqldeveloper\bin
3) Change the following line
Before:
AddVMOption -XX:MaxPermSize=128M
After:
AddVMOption -XX:MaxPermSize=256M
4) Launch SQL Developer
A memory issue of this sort will generally result in non-responsive UI behavior.
You can verify that you are hitting this issue by launching the console window version of SQL Developer and checking for memory exceptions.
C:\SQLDeveloper30-64RTMPatch1\sqldeveloper\sqldeveloper\bin\sqldeveloper.exe
A bug has been filed change this setting.
Thanks, MarkSQL Developer itself will work with a 64-bit JDK. It is possible that the data modeler still requires a 32-bit JDK.
You may get better answers in the dedicated Data Modeller forum. -
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
SanjeevI 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.

BW data model and impacts to HANA memory consumption
Hi All,
As I consider how to create BW models where HANA is the DB for a BW application, it makes sense moving the reporting target from Cubes to DSOs. Now the next logical progression of thought is that the DSO should store the lowest granularity of data(document level). So a consolidated data model that reports on cross functional data would combine sales, inventory and purchasing data all being stored at document level. In this scenario:
Will a single report execution that requires data from all 3 DSOs use more memory vs the 3 DSOs aggregated say at site/day/material?Lower Granularity Data = Higher Memory Consumption per report execution
I'm thinking that more memory is required to aggregate the data in HANA before sending to BW. Is aggregation still necessary to manage execution memory usage?
Regards,
Dae JinLet me rephrase.
I got an EarlyWatch that said my dimensions on one of cube were too big. I ran SAP_INFOCUBE_DESIGNS in SE38 in my development box and that confirmed it.
So, I redesigned the cube, reactivated it and reloaded it. I then ran SAP_INFOCUBE_DESIGNS again. The cube doesn't even show up on it. I suspect I have to trigger something in BW to make it populate for that cube. How do I make that happen manually?
Thanks.

Extremely high memory usage after upgrading to Firefox 12
After I upgraded to Firefox 12, I began frequently experiencing Firefox memory usage ballooning extremely high (2-3GB after a few minutes of light browsing). Sometimes it will drop back down to a more reasonable level (a few hundred MB), sometimes it hangs (presumably while trying to garbage collect everything), and sometimes it crashes. Usually the crashing thread cannot be determined, but when it can be, it is in the garbage collection code ( [https://crash-stats.mozilla.com/report/list?signature=js%3A%3Agc%3A%3AMarkChildren%28JSTracer*%2C+js%3A%3Atypes%3A%3ATypeObject*%29] ).
I was able to capture an about:memory report when Firefox had gotten to about 1.5 GB and have attached an image.
A couple of things I've tried. I have lots of tabs open (though the Don't load tabs until selected option is enabled), so I copied my profile, kept all my extensions enabled, but closed all my tabs. I then left a page open to http://news.google.com/ and it ran fine for several days, whereas my original profile crashes multiple times a day.
I also tried disabling most of my extensions, leaving the following extensions that I refuse to browse without:
Adblock Plus
BetterPrivacy
NoScript
PasswordMaker
Perspectives
Priv3
However, the problem still happened in that case.
Don't know if any of this helps or not. I'm looking forward to trying Firefox 13 when it comes out.hello, thanks for reporting back with detailed information.
from a brief look at your extensions i don't recognize any known (to me at least) memory leaking ones. in the last weeks there were also reports about the java plugin causing high memory consumption in combination with firefox 12 - in case you have it installed in firefox > addons > plugins try disabling it for a few days & test how firefox is behaving with many tabs.
& although probably not related to the memory problems you could update your graphics driver to get better results with hardware acceleration in firefox - this is the latest driver by intel for your model & os:

Integration Builder Memory Consumption
Hello,
we are experiencing very high memory consumption of the Java IR designer (not the directory). Especially for loading normal graphical idoc to EDI mappings, but also for normal idoc to idoc mappings. examples (RAM on client side):
- open normal idoc to idoc mapping: + 40 MB
- idoc to edi orders d93a: + 70 MB
- a second idoc to edi orders d93a: + 70 MB
- Execute those mappings: no additional consumption
- third edi to edi orders d93a: + 100 MB
(alle mappings in same namespace)
After three more mappings RAM on client side goes on 580 MB and then Java heap error. Sometimes also OutOfMemory, then you have to terminate the application.
Obviously the mapping editor is not quite will optimized for RAM usage. It seems to not cache the in/out message structures. Or it loads for every mapping very much dedicated functionality.
So we cannot really call that fun. Working is very slow.
Do you have similar experiences ? Are there workarounds ? I know the JNLP mem setting parameters, but the problem is the high load of each mapping, not only the overall maximum memory.
And we are using only graphical mappings, no XSLT !
We are on XI 3.0 SP 21

Apart from raising tablespace..
Note 425207 - SAP memory management, current parameter ranges
you have configure operation modes to change work processes dynamically using rz03,rz04.

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".

Excessive memory consumption when loading Customers through Component Inter
Hi All,
I'm facing a big problem with the high memory consumption when loading Customers, Companies and Sites using the Component Interfaces delivered by the product (RD_CONSUMER_CI_API, RD_COMPANY_CI_API, RD_SITE_CI_API) within Application Engine programs. I'm loading about 7 million customers, an amount that is not so big in my opinion, but the memory consume is too high.
We have 3 Batch Servers, each one running under Red Hat OS with 32 GB RAM memory plus 32 GB Swap memory in each server. We are running 2 Process by Server and with a day and half the servers crash with 100% of memory consumed (RAM and SWAP).
There's a good pratice to use Component Interface in a heavy load process?
There are parameters in the process scheduler configuration file that could help to reduce the memory consumption?
There's a way to free the memory through PeopleCode or by running another process?
Thanking you in advance.You may want to try and cut down on the input data to ascertain that the load might be a problem.
You may try and use the GarbageCollector, but might not help in your case.
To get an idea of the size allocated in buffer for the Rowset being used, you may want to check out the memory overhead ...
Also, could check, which is the process that is consuming a lot of memory -
Graphic failure after full on memory consumption
After few hours of usage mostly after a high memory consumption, my mac starts doing these lines. Now i never had this issue before maverick upgrade. Can someone let me know what is going on. Rebooting fixes the issue for now.
MacBook Pro
15-inch, Mid 2010
Processor 2.53 GHz Intel Core i5
Memory 4 GB 1067 MHz DDR3
Graphics Intel HD Graphics 288 MBYup, same thing happening here. Just upgraded to 10.9 Mavericks.
2010 MBP 15-inch, i5 2.4GHz.
Kind of odd that all that all of us have the same model Mac. I hope this isn't related to another issue described over here: http://support.apple.com/kb/TS4088
I just spent money to get my logic board replaced because of that issue, as the diagnostic test said I "passed" even though I was still getting kernel panics occasionally. Now I upgrade to 10.9 and see video artifacts everywhere.
Random video/graphics glitches appear all over the place after a while. Sometimes it's minor, other times it makes the system unusable as you can't see anything. Usually goes away again if you restart, but it's obvious there's some kind of graphics issue with 10.9.
