Memory leak issue with link server between SQL Server 2012 and Oracle

Hi,
We are trying to use the linked server feature with SQL Server 2012 to connect SQL server and Oracle database. We are concerned about the existing memory leak issue. For more context please refer to the link.
http://blogs.msdn.com/b/psssql/archive/2009/09/22/if-you-use-linked-server-queries-you-need-to-read-this.aspx
The above link talks about the issues with SQL Server versions 2005 and 2008, not sure if this is still the case in 2012. I could not find any article that talks about if this issue was fixed by Microsoft in later version.
We know that SQL Server process crashes because of the third-party linked server provider which is loaded inside SQL Server process. If the third-party linked server provider is enabled together with the
Allow inprocess option, the SQL Server process crashes when this third-party linked server experiences internal problems.
We wanted to know if this fixed in SQL Server 2012 ?

So your question is more of a information type or are you really facing OOM issue.
There can be two things for OOM
1. There is bug in SQL Server which is causing the issue which might be fixed in 2012
2. The Linked server provider used to connect to Oracle is not upto date and some patch is missing or more recent version is to be used. Did you made sure that you are using latest version.
What is Oracle version you are trying to connect(9i,10g, R2...)

Issue with migration DB from SQL Server 2005 to Oracle 11.2 using SQL Developer Migration workbench

Hi,
We face an issue while migrating an SQL Server 2005 DB to Oracle 11.2. It fails during the process. I hope someone on the forum has seen this before and can give us some advice.
I use the latest version of SQL Developer with JRE included (3.2.20.09). The JDBC driver to connect to SQL Server 2005 is 1.2.0
Here are the steps we take in the Migration Workbench wizard:
I made an online extract of the SQL Server database.
Using the workbench in SQL Developer I created a migration repository in schema PDM_MIGRATION.
Next I start the migration, it captures the tables fine, but immediately after the start of the conversion I get a failed message without further explanations.
This is the content of the error xml:

Does anybody know what this error means and what steps we should take to continue the migration?
I see the PDM_MIGRATION.MIGR_FILTER is a type.
Many thanks in advance,
Kris

Hi Wolfgang,
Thanks for your reply.
This is how the type MIGR_FILTER looks like:
create or replace
TYPE MIGR_FILTER IS OBJECT (
FILTER_TYPE INTEGER, -- Filter Types are 0-> ALL, 1->NAMELIST, 2->WHERE CLAUSE, 3->OBJECTID LIST
OBJTYPE VARCHAR2(40),
OBJECTIDS OBJECTIDLIST,
NAMES NAMELIST,
WHERECLAUSE VARCHAR2(1000));
I think the repository user has the correct privileges. This is the overview of privileges it has:
SQL> select * from dba_sys_privs where GRANTEE in ('PDM_MIGRATION') order by GRANTEE;
GRANTEE PRIVILEGE ADM
PDM_MIGRATION ALTER SESSION NO

Connectivity issue with local instance of sql server

hi everbody,
well for the last couple of days i have almost taken my head out to get this issue resolved.
but still i am no where. i have already referred to so many tips available online but still can't fix the prob.
i am trying to connect a C# ( .net 2005) program to connect to the integrated sql server 2005 instance on my local computer.
i have got windows 7 home basic on my pc with .net frame work 2.0 sp2 and have also upgraded to sql server 2005 sp3 as per some online study.
i have also tried all these steps but still getting the error 40.
1. Check Whether the SQL Server is running or not.
Because the trial to connect to the stopped server may also cause this problem.
2. Check the name of the SQl Server.
For example, if we try to connect to SQL server using .NET application, for some SQL Server, the name of the server "localhost" works, but for some server, we may need to mention "(local)".
3. Check Whether the SQL Browser Service is running
4. Check Whether the TCP/IP is enabled for SQL Server Configuration
* Expand SQL Server Configuration Manager
* Enable TCP/IP
5. Firewall Settings
You may need to add the port of Sql server to the Firewall if it is other than the default port(1433).
Go to Control Panel | Windows Firewall | Change Settings | Exceptions | Add Port
6. Enable the Remote Connection
Goto SQL Server Management Studio.
Right Click on Server node
Click On Properties
Check the Allow Remote connections to Server Check Box
7. Enable Named Pipes
- Open the "SQL Server Configuration Manager" (under Configuration Tools)
- Expand the "SQL Server 2005 Network Configuration"
- Select the "Protocols for "
- Set the Named Pipes To Enabled
8. Create Exception of Sqlbrowser.exe
kindly provide me some help with your valuable suggestions.

Hi Mukesh Devrani,
Thank you for posting.
Your question is more like SQL. I suggest that you can ask your question in SQL forum.

Memory Leak issue with TreeView

Hi,
I get Memory Leaks in the TreeView, if I open the stage which contains the TreeView several times.
Everytime I open the stage, I clear the TreeView and populate it with new items.
However there are leaks.
I think this is a bug. But maybe my code is wrong and someone could comment on this issue.
See this test case:
i < 10: 5854 KB
i < 100: 35944 KB
i < 200: 64515 KB
import javafx.application.Application;
import javafx.event.EventHandler;
import javafx.scene.Scene;
import javafx.scene.control.TreeItem;
import javafx.scene.control.TreeView;
import javafx.scene.layout.VBox;
import javafx.stage.Stage;
import javafx.stage.WindowEvent;
public class TestApp3 extends Application {
    public static void main(String[] args) throws Exception {
        launch(args);
    public void start(final Stage stage) throws Exception {
        VBox root = new VBox();
        SubStage subStage = new SubStage();
        for (int i = 0; i < 10; i++) {
            subStage.show();
            subStage.hide();
        System.gc();
        System.out.println((Runtime.getRuntime().totalMemory() - Runtime.getRuntime().freeMemory()) / 1024 + " KB");
        Scene scene = new Scene(root);
        stage.setScene(scene);
        stage.show();
    private class SubStage extends Stage {
        public SubStage() {
            TreeView<String> treeView = new TreeView<String>();
            final TreeItem<String> rootNode = new TreeItem<String>("Root");
            treeView.setRoot(rootNode);
            setOnShowing(new EventHandler<WindowEvent>() {
                @Override
                public void handle(WindowEvent windowEvent) {
                    rootNode.getChildren().clear();
                    rootNode.getChildren().add(new TreeItem<String>("Item"));
            Scene scene = new Scene(treeView);
            setScene(scene);

Hi. If You replace
    rootNode.getChildren().clear();
    rootNode.getChildren().add(new TreeItem<String>("Item"));
with:
     rootNode.getChildren().setAll( new TreeItem<String>("Item"));
You will get the following:
i < 10: 2881 KB
i < 100: 3341 KB
I <200: 3478 KB

Memory Leak Issue With Win7 64 bit and Youtube.

I have a Win7 64 bit using IE9 with version 11.4.402.265 installed. 4 MB installed.
Whenever I go to Youtube or Liveleak, and watch videos, over time it uses up to 4gigs of my memory! Even if I close the window, it does not free up the memory until I Ctrl/Alt/Delete and shut down the window(s).
I normally only keep open 1-2 windows. Google toolbar is about the only thing installed. I can open 5 and more tabs, but as long as the site does not use flash, I don't have issues and each window usually uses under 200k memory watching them in task manager.
When I go to open and watch a youtube video, it slowly climbs to 200k and within an hour, I can be at 2 gigs or more memory and up to 4 gigs within 2 hours (or sometimes much sooner). Closing the window does not release the memory until I end task on it and then after a minute or so, the memory seems to clear and everything is back to normal.
I searched the forums and seems lots of users, report memory leaks, some using yahoo toolbar installed, which is not my case. I do use yahoo as my e-mail address, no idea if that is related or not. I had the same issue when I had the prior Flash version installed, this has been going on for months. Right now having only this window open, using 129, 192 memory. If I open one more window (using the 64 or 32 bit browser) and start youtube, the memory in that window keeps climbing about 50-100kb a second, so it adds up quickly. I have kaspersky running in the background and that is about it other then my nvida driver setup.
Really frustrating that so many people here and across the internet have reported this. I did have IE8 a few weeks ago and still had the same issue, upgraded to IE9 to see if that helped.
Interesting side note, if I pause a video, it slows way down on the memory leak, but still rises at a slower pace. I don't know if this is an IE thing or Flash. I have had this setup since 2009 and don't recall having issues with IE7. I use Youtube so much as a teaching instrument as a music teacher, so constantly have lessons going on it.
Thanks and hope someone has come up with something. I also build computers and have done some programming, so I could modify a file if needed with clear instructions.

This could be similar to bug https://bugbase.adobe.com/index.cfm?event=bug&id=3334814

Memory leak issue with static basicWriteLockInfo

Hi,
I am using JE 3.3.69 and am seeing a memory issue that I do not see with JE 3.2.76. The application loads the database (filling the DB cache in the process), fully closes the environment, re-opens the environment, and then preloads databases until the DB cache of the new environment is full. What seems to be happening is that the the DB cache from the closed environment is never garbage collected and the preload causes an out-of-memory error since the heap is not big enough for two full caches.
I saw that there is a static field in WriteLockInfo referencing a database (through the abortDb field) and is thereby holding on to the objects that make up the DB cache of the closed environment.
static final WriteLockInfo basicWriteLockInfo =
new WriteLockInfo();
Should this static field belong to the environment instead?
Is there a work-around I can try?
Thanks,

This bug, or something very similar, still exists for databases using the shared cache.
The whole shared cache ends up leaked.
I don't know what is causing the leak, and if it is the same or similar internal cause as the previous bug.
I can confirm that for databases using their own (non-shared) cache, it no longer occurs but did in the past.
Reproduction:
Open Environment A (large) with locking disabled, using the shared cache, set the cache to a known percent value.
Open Environment B, C, D, etc in the same shared cache
Access Environment A until a large amount of RAM is used by the cache. Stop activity. Garbage Collect. Note remaining heap size (JConsole, Jstat, JMX, various other ways).
Open Environment A2 (same thing, different dir -- in our case we are swapping out updated data).
Close Environment A. Garbage collect -- no difference in size. Note, A2 has not been accessed at all.
Access Environment A2 again causing more memory to be used. It will grow well past its previous level above.
Open Environment A3.
Close Environment A2. Garbage collect -- it will free up all the stuff associated with A2, but all the stuff from A still remains.
The effect is as if the first shared lru cache is lost. Repeated opening and closing recycles the memory properly. But whatever is accessed in the "first" opening is lost forever.
When you use a cache that is 40% of the heap size (3500MB heap) and you lose 40% of the heap, its bad.
We are unable to use the shared cache feature due to this bug, though we are thinking about investigating a purposeful open/access/close upon startup to work around it.

HT203175 Is anyone having memory leak issues with 64bit Windows 7 and iTunes?

iTunes runs for a period of time and then a dialog box appears. It takes longer if you let the program change tracks as in a playlist. You can accelerate the process by picking a new song after they play for a while (double click). Eventually, you get a dialog box that states - The iTunes Library file cannot be saved. An unknown error occured (-50). Eventually, the program locks up.

One thing that you can try that i read was disable the iTunesHelper.exe program either by the msconfig program or just disable the service. Appearently this can cause a similar issue. All this program does is open iTunes when you connect your iPod to your USB port. I am wondering what 64bit patches you guys are on? Maybe if you list them we can figure out if some Microsoft patch is causing this issue, a circumstance, or bad programming from Apple. I will review my system and list my patches tomorrow. I dont remember this always happening, nor do I remember it only happening after an upgrade to the iTunes.exe or iTunes files. Sometimes, things seems a certain way until you really find out their root cause. I am still trying to find some time to finish debugging the application. I didnt realize how big the symbols directory was for Microsoft. I am finding myself juggling disk space since i am using a laptop.

What is the best way to deal with memory leak issue in sql server 2008 R2

What is the best way to deal with memory leak issue in sql server 2008 R2.

What is the best way to deal with memory leak issue in sql server 2008 R2.
I have heard of memory leak in OS that too because of some external application or rouge drivers SQL server 2008 R2 if patched to latest SP and CU ( may be if required) does not leaks memory.
Are you in opinion that since SQL is taking lot of memory and then not releasing it is a memory leak.If so this is not a memory leak but default behavior .You need to set proper value for max server memory in sp_configure to limit buffer pool usage.However
sql can take more memory from outside buffer pool if linked server ,CLR,extended stored procs XML are heavily utilized

SQL Server 2012- Memory Leak Issue

Team,
We are running a Mission Critical Application on SQL Server 2012 SP2(11.0.5058) which is configured on Always ON Synchronous mode. Offlate due to heavy development work, Application team have come up with stating memory issues. I have analysed all the areas
and everything looks normal. Please suggest if we have to patch the latest CU4 for SQL Server 2012 SP2.
The checks were performed on the below areas:
- Errorlog, System Logs - No errors reported.
- There are close to 8 Databases hosted on the instances which are all configured for AlwaysON. SQL Server is running on VM Infrastructure and the total physical memory allocated is 96GB out of which SQL is capped for 92GB.
-The Page Life Expectancy is healthy and is showing a greater number. There are no Signal waits either or pending memory grants.
- The writes are more than reads for one of the databases which is flagged with application team. There are no blockings & Deadlocks.
Please suggest me the future course of action and your inputs are much appreciated.
Best Regards,
Sharath

Actual issue is- Application team have reported a memory leak and their builds have significantly slowed down. They suspect that its Database memory leak. However I have verified from database end and gave the above inputs.
The AOAGs are good. I was looking for any pointers whether there are any bugs which is related to memory leaks in SQL Server 2012. I know all of them are addressed with SQL Server 2012 SP2.
Application team has NO idea about SQL Server do they ? And to say SQL Server has memory leak you have to actually prove it did they showed any proof. Its common for application team to say SQL Server is leaking memory because they are unaware about fact
by default SQL Server would take as much memory as possible and would release when SQLOS asks it to do so. This might give sign that it is leaking memory BUT IT IS NOT.
As you already said AOAG is working fine so I am presuming there is nothing much to worry. To monitor memory usage in SQL Server 2012 you can use below counters
SQL Server: Memory Manager-- Target Server Memory (KB)
SQL Server: Memory Manager--Total Server Memory (KB)
SQL Server: Memory Manager- Free Memory (KB)
SQL Server: Memory Manager--Database Cache Memory (KB)

PGA memory Leak issue along with TNS: listener could not hand off client connection

Hi,
We have two Oracle Database instances in a 32 bit Standard Edition Windows OS machine with 3 GB RAM : 1) 1525 MB (SGA+PGA) 2) 515 MB (SGA+PGA)
Recently we upgraded the RAM from 3 GB to 4 GB. Subsequently we upgraded the SGA + PGA of the 2nd instance to 771 MB.
This has resulted into PGA memory leak issue reported in the alert log file and trace file.
Reverting back the SGA+PGA size to 515 MB solved the issue.
Is this issue related to Address Windowing Extension (AWE)?
Is the reason related to Total memory for all the cumulative Oracle instance should be < 2GB.
How to solve this?

There may be something fixed in the patch that gives the error rather than mysterious hangs. I would prefer that, myself. There may be something in the patch that changes how Oracle allocates user, system and program areas.
At some point you spend more trying to limp things along in a growing environment than simply upgrading. 32 bit environments these days is an indicator that management is figuring some false economies. But that's their prerogative.
The PGA can be affected by many things, not least of which is how the application uses it. Much has been written about it, my own experience has been more is used than most people say. But that is probably just my app. Note there are different ways to set it, and a parameter with "target" in it might not be a hard limit. Different execution plans for the same code may use different amounts of memory - there can even be situations where forcing some code to use a sort area instead, or even forcing more operations to disk, can free up more pga for everyone else. It depends. But that's why I look at multi-pass operations in dbconsole.

Linked Server error: Login Failed for user 'NT AUTHORITY\ANONYMOUS LOGON' between sql server 2005 32 bit and sql server 2012 64 bit

Hi All,
Here the linked server is created between sql server 2012 64 bit and sql server 2005 32 bit. I am getting the below error when i try to access linked server from third server. I have created linked from Instance 1 to Instance 2. When i access it from
instance 3 i am getting the below error. SPN setting has been done between these 2 servers. Also the option 'Trust the delegate' is enabled for the both the service account.
'Login Failed for user 'NT AUTHORITY\ANONYMOUS LOGON'
Appreciate your quick response.

Oracle InstantClient with Linked Server in Sql Server 2005

We are trying to connect ORACLE server from sql server 2005 using Linked Server Feature in SqlServer 2005
Generally Oracle Client software is needed for this activity in the sql server machine.
Can we use "Oracle InstantClient" instead of "Oracle Client Software" to connect ORACLE using Linked Servers ?
Please give us your views, any existing reports similar to this activity
Thanks & Regards,
Palani

Thanks for your reply
I agree that Oracle Client software is used to connect oracle from SQL SERVER 2005.
But my doubt is can we use Oracle InstantClient instead of Oracle Client software to connect oracle from SQL SERVER 2005
with respect to Oracle Instant Client - I would like to know the development steps (Not the installation steps of Oracle Instant Client in windows machine) to connect ORACLE server.
Thanks & Regards,
Palani

Why SCCM 20012 Install fails with remote 64 bit SQL Server but proceeds for remote 32 bit SQL Server

I have the following setup:
AD User accounts
- SQLAdmin (used to run SQL Services i.e. Database Engine)
- SCCMADmin (used to install SCCM 2012)
SPN registered for user account SQLAdmin
setspn -S MSSQLSvc/SQL.Domain_Name:1432 Domain_Naem\SQLAdmin
setspn -S MSSQLSvc/SQL:1432 Domain_Name\SQLAdmin
setspn -S MSSQLSvc/SQL.Domain_Name:1433 Domain_Naem\SQLAdmin
setspn -S MSSQLSvc/SQL:1433 Domain_Name\SQLAdmin
and checked with setspn -L TESTING\SQLAdmin
1 SERVER called SQL

64bit Server that is to be the Primary Site Server\MP for SCCM 2012
ODBC link to SQL\SCCM2012,1432
ODBC link to SQL3\SCCM2012,1432
ODBC uses SQL Native Client 10.0 (64 bit)
Both ODBC connections when TESTed pass and suggest connectivity to SQL Servers
Install process doe SCCM2012
Tried to install SCCM 2012 RC2 when logged in to SCCM Server as AD user account
SCCMAdmin, and when utilising the SCCM2012 SQL instance on
32 bit server of SQL install proceeds barring warning about 8GB rec, for SQL Server. Then fails on PKI certificate issue. Installation (chose HTTP for MP). I beleive the PKI failure as install starts is
due to the fact that SCCM 2012 needs its database server to b 64 bit ?
Thus i then tried to install SCCM 2012 RC2 when logged in to SCCM Server as AD user account SCCMAdmin, and
when using the SCCM2012 SQL instance on
64 bit server of SQL install proceeds but fails at checking stage and says:
SQL Server sysadmin rights FAILED SQL3.Domain_Name
Either the user account running Configuration Manager Setup does not have sysadmin SQL Server role permissions on the SQL Server instance selected for site database installation, or the SQL Server instance could not be contacted to verify permissions. Setup
cannot continue.
and
Site System to SQL Server communication WARNING SCCM.Domain_Name
A communication error has been detected between the specified site system and the site database computer. This error can occur when the site database server is offline or if a valid SPN has not been registered in Active Directory Domain Services for the SQL
Server instance hosting the site database. Setup cannot continue.
Why does the install of SCCM 2012 with 32 bit SQL proceed further than the install with 64 bit SQL, with the latter process failing as above error meesages show and yet both servers are set identically (apart from temporary turning off Firewall on the 64
bit server) and during the install the Databse Server specified is accepted ?

Thanks for the reply.
I can connect via ODBC to the the 32 bit SQL Server and the 64 bit SQL Server from the SCCM Server
The SQL Server Unit called SQL3 unit is a 64 bit SQL.
The SQL Server Unit called SQL is only 32 bit, but at least gets past the final checking stage and the error messages about sysadmin rights and Site System to SQL Server communication problem, and then fails with PKI certificate error message.
When trying to install SCCM specifying the 64 bit SQL Server as the Database Server it gives the 2 error messages at the final checking stage of the installation as listed.
So as I said what is confusing is the fact that if the SCCM install uses the remote 32 bit SQL Server it passes the final checking (although fails with PKI certificate message) but the 64 bit SQL Server set up exactly the same apart from the Firewall being
left off for the time being, fails at the final check stage with the 2 listed errors.
If I use a local 64 bit SQL Server the installation is fine.
Still would like to find out what cause the 2 issues for the remote 64 bit SQL Server, when ODBC seems fine, sysadmin rights have been given for the installer account and the SCCM computer account and SPNs have been set for the user account running the SQL
Services.

Difference between SQL SERVER 2008 & SQL SERVER 2012 & SQL SERVER 2014

Difference between SQL SERVER 2008 & SQL SERVER 2012 & SQL SERVER 2014 ?

What sort of databases do you have OLTP? Data warehouse? What requirements do you have for High Availability?
The main features for SQL 2012/2014, as I see it:
o Support for window functions, which makes it possible to write fast queries for running totals, sliding windows etc.
o Columnstore indexes, which can speed up your data warehouse enormously. But of no interest for OLTP. Only writable in SQL 2014.
o AlwaysOn and Availability Groups, a vastly improve story for high availability and disaster recovery.
o try_convert/try_cast, you can now easily filter out values from a column which does not convert to a number. A small but essential feature.
o In memory-OLTP, a new in-memory engine in SQL 2014. This far with very limited feature set, and quite specialised.
Of the points above, the second and third require Enterprise Edition, the first and fourth are in all editions. For the last, I don't think Microsoft has announced anything yet.
There are also new stuff in the BI area, but that's out of my league.
And, oh, there is a new licensing model - which I think is holding more than one customer back.

Is this a memory leak issue ?

We are using Jdev10g + BC4J + Struts + JSP to build our enterprise application,
but when the application running some days in our Application Server(RedHat AS3-86, with 4GB RAM), the memory consumed is serious ! we doubt and worry
about maybe our application suffer the memory leak problem, so we want to know have the command to find out whether our application caused the memory leak
issue and which program is the major murderer for memory.
In EM console , the memory utilization chart have big memory consumed in "other" legend ? the "other" legend is mean what ? I cannot find the consumer process in system level through ps command ? it seems disapear ! but after I reboot the server , the "other" legend is clear !

The second scenario is, as we perform some deployment activity on 10g, the memory usage chart shows a sharp consumption of memory about 1.5GB .the loss memory almost be display in "other" legend chart !
Please give us some advice , thanks in advance
