Multiple oracle exe process

Hi,
I am using 10.2.0.1.0, 64 bit version on windows.
In our schema if we execute one query multiple oracle exe process are created for same query. Nearly 20 process are created. I am seeing this result on toad session browser.
Could any one tell me why these much of process are creating.
Thanks,
Ratna.

Looks like parallel query.

Oracle.exe process active at 9pm GMT

At 9pm GMT every night the oracle.exe process leaps into action and starts doing something.
What is it doing and how do I control it?

David is right. Do selects from dba_scheduler_jobs and dba_jobs to see what scheduled tasks occur at around that time.
If they are scheduler jobs then dba_scheduler_job_run_details and dba_scheduler_job_log may provide more info.
Hope this helps,
Ravi.

Acrobat X intermittently won't launch, multiple Acrobat.exe processes hanging in task manager

Apologies if this is in the wrong community area - I was unsure where it belongs.
This is an intermittent issue, but does happen several times a day.
Regardless of what method is used to launch Acrobat (double-clicking a PDF, clicking the shortcut in the taskbar, selecting Acrobat from the start menu), often the application won't launch. Upon investigation, task manager shows multiple instances of Acrobat.exe, although the application is not running (see the image below). Ending all Acrobat.exe processes does allow Acrobat to launch.
Any thoughts as to what might be causing this, as well as a more permanent fix? The workaround of constantly ending multiple processes is becoming cumbersome.
We are running Acrobat X Pro in Windows 7. I also have several CC 2014 apps installed (as well as a couple of earlier versions required for plugin functionality).

This happens all the time in my company with several installs of Acrobat.
The only way to fix this for us is to end each process in Task Manager as you have pointed out.
It is very time consuming in our workflow as we each operator deals with hundreds of PDFs daily, and has to do this End Process procedure several times a day.
We have done several tests and nothing seems to stop this from happening.

PS CS5 Std - Multiple Photoshop.exe Processes Seen Running

Interesting. On a couple of occasions I have spotted more than one Photoshop.exe process running in Task Manager. It was a curiosity and I ignored it, thinking perhaps Adobe was doing something special to split up the work.
Today, when updating to Camera Raw 6.1, I saw the message that follows:
Sure enough, even though I had closed the Photoshop application I started the update from, there was a Photoshop.exe *32 running. Killing that process yielded success with the update, but given that I have read several accounts where people have said they've seen the above error as well, I wonder whether there's a systemic problem with PS CS5.
I have Photoshop CS5 on Windows 7 x64 Ultimate. My system is stable otherwise, clean of malware and well maintained.
I realize the Windows environment is one in which anything can and does happen, and believe me I will be checking the health of my system in every way I can, but given that I carefully maintain this system I ask that you please don't discount this problem as a one-off on my particular computer because of something specific I have that's gone wrong.
Those of you running an x64 OS, please start your Task Manager, Processes tab. Do you see more than one Photoshop.exe (or a Photoshop.exe process when you're not running it).
-Noel

No, whatever variant (32 bit or 64 bit) you started stays running. Normally an attempt to start either one afresh brings the currently running variant to the top. For a very brief period both are running, but I assume the second one up discovers that the first one is running and just activates it.
I have just reproduced the problem, by the way... After a fair bit of editing I was running the Genuine Fractals 6.04 plugin and the plugin trapped out. Now there is an "orphan" Photoshop.exe *32 process just sitting there, with no window... It's not actively using any cpu time.
I can't expect Adobe to be concerned about faults arising from 3rd party plugins trapping out, but I'm sure I've seen this issue without that happening. I will report back if I see it again.

Multiple javaw.exe processes

I've been working with Java on the Mac platform for quite a while now, but we've been noticing a Windows XP problem at work that is over my head:
"A javaw.exe process is launched each time I start the app. Quitting the program does not kill the javaw.exe process. After starting and quitting the app a number of times, my system's performace really starts to degrade. I have to manually kill all of the javaw.exe processes to liberate my RAM. "
Normally we open it just by double-clicking the jar file (since it has a manifest in it), but we've also resorted to using the console the open it. Nothing seems to make a difference.
I'm positive that System.exit(0) is being called after I save everything and close all my windows (I added console output to verify that).
Am I misusing System.exit()? Does anyone have any experience with this problem, or knowledge of the subject?

i don't believe that System.exit() is called. just
insert a Syste,.out.println() just before
System.exit() to check if it is really called.I already did. (That's why I said before "I'm positive it's called".)
This took days to hunt down, but today we finally figured it out (and a work-around):
The problem was a shutdown hook. (See Runtime.getRuntime().addShutdownHook(). )
I use them to save preferences, write an error log, and close up QuickTIme.
Apparently on Windows if you call QTSession.close() in a shutdown hook, the thread blocks. And any shutdown hook that blocks will keep the JVM from closing -- so if you're experience a similar problem check your shutdown hooks. And pray to the great computing gods in the sky that you're not using packages that abuse their own shutdown hooks.
I suspect the problem is that QuickTimeJava added its own shutdown hook, putting a synchronization lock on the ability to edit the current state of QTSessions. I say this because I could safely call: QTSession.isInitialized(), but QTSession.close() or QTSession.terminate() caused a deadlock.
The workaround:
My code now says:
MovieUtilities.shutdown();
System.exit(0);
where the method shutdown is simply:
//note that there might be several QTSession's open
while(QTSession.isInitialized()) {
QTSession.close();
This keeps Windows machines from blocking, and the javaw.exe processes terminate normally.

Opening PDF spawns multiple AcroRd32.exe processes.

I have a user that when he opens any PDF he'll get 4 AcroRd32.exe process spawned the first time. When that one is closed, 2 of the 4 process end. When another PDF is opened, 2 processes start, but only one ends when the PDF is closed. So after 5 PDFs are opened and closed, 6 AcroRd32.exe processes are still running.
So far all we've done is reinstalled Adobe Reader XI. Anything you guys know on how to fix it?

Hi chubbcheese,
Thank You for posting on the forums. Kindly help with the information listed below.
1) Operating System
2) Version of Reader (E.G.11.0.06)
3) What kind of PDF is it, PDF producer
Thanks,

OPMN Controlling Multiple Oracle Home Processes

OK,
Have OC4J,HTTP in a 10.1.3 Oracle Home.
Have Webcache in a 10.1.2 Oracle Home.
GOAL: opmnctl <start|stop> controls all processes (OC4J, HTTP Server, 10.1.2 Webcache).
Is it possible to have 10.1.3 OPMN control the webcache process in the 10.1.2 Oracle Home? Would this be implemented via OPMN's custom process fuctionality or some ONS/OPMN discovery mechanism?
Thanks,
KB

Interesting how OPMN claims to support Grid computing but it can't (in a supported manner) support processes in multiple OHs ON THE SAME BOX! I guess I'll build a shell script.
And yes, opmnctl is working in both the OHs.

Size of oracle.exe

Hi,
I have installed Oracle8i (8.1.7) for NT. I sized SGA to require about 15MB. But when the instance initiates, the oracle.exe process is getting about 30MB of memory! Do you know the reason??
Thanks in advanced,
Carlos

If you are running 32-bit Windows, then it doesn't matter that you've got 8GB physically in the box: that's a common over-configuration. A 32-bit Windows system can only see 4GB of RAM -and only 2GB of that is available to user-mode programs like Oracle.
If you use a /3GB switch, you can let user-mode programs see 3GB instead of 2GB. But that's your lot.
Unless you are also using a /PAE switch, though that has interesting interactions with the /3GB switch and everything else!
Let's assume you're using a bog-standard Windows environment with no odd boot-time switches. That means 2GB is your limit. And that's for everything Oracle might want to use it for: PGA and SGA alike. I don't know how big your PGA needs to be, but assume a worst-case: allow 50% for the PGA, and 50% for the SGA. That means your SGA_MAX_SIZE parameter should be no bigger than 1GB.
For some reason, you say this sort of thing is "not an option". That's fine: but then you live with the massive swapping to disk that will ensue if you don't keep within bounds. Your choice, really.
From memory, LOCK_SGA does indeed work. But if you're locking into memory an over-allocation of SGA, you'll just be making your paging problems worse.

System cpu goes 50% to 100% process is oracle.exe

My server cpu goes high 50% to 100% and process is oracle.exe.Database is oracle8i and windows 2000 server.machine is dell power edge 2800.
problem is in oracle database or in machine or in os

It is difficult to guess
but most probably it is your Db which which may be causing
There may be so many reasons for this
It is happenig intermittently?
What is happening at the DB level during 100%?
Any batch process?
any Reporting ?

How to install Oracle BPEL Process Manager for OracleAS Middle Tier

hi,
i need to install BPEL process manager, so i download the following file from otn
1.soa_windows_x86_101310_disk1
2.soa_windows_x86_bpel_101310
here i read the document named b28980.pdf from bpel\doc\pc.1012 to install BPEL PM
so i start to complete the pre-installation task
1.installed Oracle database 10g
2.Run the Integration Repository Creation Assistant on the Database
3.Install Oracle Application Server 10g Release3 (10.1.3.1.0) and select either the J2EE Server installation type or the J2EE and Web Server installation type. selected J2EE and Web Server installation type
and installed according to the Oracle application server installation guide.
installed OracleAS in the path : D:\product\10.1.3.1\OracleAS_1
4.Install the current release of Oracle BPEL Process Manager for OracleAS Middle Tier
here they mention to select the J2EE and Web Server installation type because that type is selected in Oracle AS installed in Oracle Application Server
so i start to install the BPEL PM by selecting the setup.exe-->and shows the location source and destination
default destination is : D:\product\10.1.3.1\OraBPEL_1 selected next on the screen
the next screen is select installation type here there are two types named
1.BPEL process Manager for Developer (371MB)
2.BPEL process manager for Oracle AS Middle tier (107MB)
i selected 2.BPEL process manager for Oracle AS Middle tier (107MB) and click next
pop up window opens with title dependencies
error:
BPEL Process manager for oracle AS Middle tier will run on top of a supported Oracle Application Server 10.1.3.1.0 J2EE server and Web Server Or J2EE server instance. this location does not contain this instance. Please select new Oracle home that contains a supported instance.
so i changed the destination path to : D:\product\10.1.3.1\OracleAS_1\BIN then also i got the same error.
please any one mention the path for J2EE and Web Server instance for installing the BPEL PM for Oracle AS Middle Tier.
Thanks in Advance
Aswath Thaniga

If you choose the developer version you will be fine.
If you have installed J2EE and Web Server installation into D:\product\10.1.3.1\OracleAS_1 then this is the location you install your BPEL PM into, not D:\product\10.1.3.1\OraBPEL_1 or D:\product\10.1.3.1\OracleAS_1\BIN.
D:\product\10.1.3.1\OracleAS_1 is what we call the ORACLE_HOME, generally we create a new home for each install, but in this case there is a dependency on 10.1.3.1 OC4J container. So it needs to be installed into 10.1.3.1 oracle home.
The bin directory is just the executables for that home, its not the actual. home.

Oracle.exe taking high memory

Hello,I got an error Ora-04030:-ORA-04030: out of process memory when trying to allocate 3842688 bytes (session heap,kgich) on oracle 11gr2 On windows 8.
My ram is of 16gb
sga_max_size =8g
Pga_aggregate_target=1.5g
Oracle.exe goes upto 15gb.
how it is possible?
please reply...

Simple: Oracle processes are implemented as threads within Oracle.exe. So you all of your sessions communicate with a corresponding thread in the Oracle.exe service. Evidently those threads consume memory.
A SGA of 8 Gb, 50 percent of physical RAM, looks a bit outrageous to me.
Also Windows 8? That is not even yet released! Did Oracle certify 11gR2 against Windows 8? No doubt they didn't, they never certify against newer releases!!

EXCEL.EXE process is keep running even after closing all the handles

I am using Excel Report Instrument functions for creating excel application and sheet,workbook after reading/writing in to excel file am closing all the handles using CA_DiscardObjHandle (handle);     even after file is getting closed m checking it in TaskManager then one EXCEl.EXE process is keep running there,pls let me know how to deal with this....
Solved!
Go to Solution.

A Kumar:
Have you tried running the example program excelreportdemo.prj that ships with CVI? It ends the excel process by discarding multiple handles, and it works even if you're editing a cell or have an Excel dialog open, etc. Try running this without modification and verify that the excel process is closed when you quit the CVI app.
Here's the Quit function from excelreportdemo. It checks for and closes handles for the worksheet, chart, workbook, and excel application.
int CVICALLBACK Quit (int panel, int control, int event,
        void *callbackData, int eventData1, int eventData2)
    switch (event)
        case EVENT_COMMIT:
            if (worksheetHandle)
                CA_DiscardObjHandle(worksheetHandle);
            if (chartHandle)
                CA_DiscardObjHandle(chartHandle);
            if (workbookHandle)
                ExcelRpt_WorkbookClose(workbookHandle, 0);
                CA_DiscardObjHandle(workbookHandle);
            if (applicationHandle)
                ExcelRpt_ApplicationQuit(applicationHandle);
                CA_DiscardObjHandle(applicationHandle);
            QuitUserInterface (0);

Is this a new application on this database?
Has it run well in the past?
I have had this happen before on a 32bit Windows server. Our problem was a poorly written procedure that kept pegging the cpu to 100%. You should be able to figure out what SQL is being used that is causing this problem, it will be the Top Working SQL most likely.
I also had this problem on a Logical Standby server which was trying to apply SQL to the SYS.AUD$ table. As soon as SQL Apply was started, the CPU went to 100%. Once I truncated that table, the cpu usage went back to normal. Not sure what you are using to monitor your database but if you can, try to find out what SQL is running when your CPU goes to 100%.

Shared Services 9.3.1.1 HyS9SharedServices.exe process

We recently started to notice that the HyS9SharedServices.exe process grows to use 1GB of memory. Currently this isn't causing any known issues, there aren't many users in the system. However about a month ago we had major performance issues with HFM / Smartview while there were "a lot" of users in the system. The problems in HFM were slow logins and slow switching between HFM applications. Smartview logins were also slow. Once in the HFM app things seemed to be fine. This lead us to look at Shared Services and we noticed that the HyS9SharedServices.exe had grown to 1GB.
Note: there was nothing in the Shared Services logs including in debug mode.
Ticket was opened with Oracle support and they first had us install HFM patch 9.3.1.4.10 siting this defect: 9056633 - HIGH NUMBER OF PROVIDER QUERIES WHEN USER BELONGS TO ONLY NATIVE GROUPS
Our user security is MSAD accounts belonging to native groups so this patch made sense and seemed to resolve the issue. Oracle also had us upgrade Shared Services to SP1 so we're now on 9.3.1.1 previously on 9.3.1.0.13
We've been monitoring the memory usage of the HyS9SharedServices.exe process over the last month and while it typically sits somewhere between 150-250MB memory usage twice, including yesterday we watched it grow to 1GB and get stuck there. Our servers are rebooted every Sunday so we expect the process to drop back down to normal again in a few days. Meanwhile we're concerned that something is triggering it to grow and get stuck at 1GB but we don't know what or if this is something that we should be concerned with. Oracle support is still working with us but still doesn't have much on this.
One other thing of interest when looking at various logs, for example the SharedServices_Memory_Profile.log you can see memory use is ~25455 kb right up until it jumps to 167091 kb and then to 681665 kb starting at 12:01pm yesterday right when the process started to grow. Then at 12:11pm according to the log it's back down to 25516 kb but this is not how windows is reporting it as it's still currently showing it at 1,059,676 K. Could this just simply mean that windows isn't reporting things accurately or is it tomcat? Any one have any ideas?

One of the problems that show similar sysmtoms is data explosion, caused by poorly written rules. Rules can dramatically populate a database with many more values than what was loaded from the source system. To determine if this issue is affecting your application, first determine how many records are in the DCE (Entity) table and see how close that is to the number of records in the load file. You can run a query that will order all the records, and give you a count of how many records there are for each account. Look for accounts that have dramatically larger frequencies than others, and then trace them back to the source. Do the same for the DCN (Node) table.
The results of this can be compared with your load file to determine if you are experiencing data explosion from rules.
Are you getting any subcube warnings in the HSVEvent log?
