ORAStack Utility

I'm gettign the TNS Listener error
TNS-12518: TNS:listener could not hand off client connection
TNS-12560: TNS:protocol adapter error
TNS-00530: Protocol adapter error
32-bit Windows Error: 2: No such file or directory
I deployed the patch and added some of the recommended parameters from orcle but did not resolve the issue. When this error occur, the news users are not able to opne any new connection to the database.
Now I'm thinking to reduce the Stack size from 1MB to 500k. by using
orastack oracle.exe 500000
orastack tnslsnr.exe 500000
Is there any disadvantages by using this ?

This could be used, but I strongly suggest you to validate with Oracle Support before you apply this change. There are several situation where the use of orastack is advised, but not only on listener, but also on the oracle.exe, and it is used to reduce the stack size, but if you undersize it your RDBMS may be rendered unstable, so watch out.
I've got documented a clinical case where I required to reduce the stack size due to an excessive resource consumption after migrating from 9iR2 to 10gR2 on a Windows 2003 platform --> Issues found when upgrading to 10gR2, and The Orastack Uitlity.

  • Problem in using ORASTACK utility

    when I try to reconfigure memory consumption by each connection by orastack utility it throws the below shown error...
    G:\oracle10G\BIN>orastack oracle.exe 500000
    Couldn't open file with CreateFile()
    GetLastError() == 32
    whereas simply orastack succeeds..
    G:\oracle10G\BIN>orastack oracle.exe
    Dump of file oracle.exe
    Current Reserved Memory per Thread = 1048576
    Current Committed Memory per Thread = 4096

    Hi Anirban,
    maybe I am a little late...
    but I guess you receive that error because oracle.exe is in use.
    You have to shutdown all instances on the node before modifying the stack size.
    (orastack oracle.exe simply shows the current values without changing anything)

  • Problem In utilizing "ORASTACK" utility

    Dear all
    I want to chang default stack zise of a thread/session, when i try to reduce stack of every session created int the oracle executable for serving more users it show some error.
    ---------------------Current size------------------------------------------
    c:\> oracle\product\10.2.0\db_1\bin\orastack oracle.exe

    How i can resolve this problem.
    Thanks in advance

    After shutdown database i thry changing stack size
    It is used primarily to address the ORA-04030 error on Windows servers. The oerr output for the ORA-04030 error is:
    04030, 00000, "out of process memory when trying to allocate %s bytes (%s,%s)"
    // *Cause: Operating system process private memory has been exhausted
    // *Action:
    This error occurs when Oracle is trying to allocate memory for the session but none exists. Windows NT has a limitation of 2 GB of RAM allocated for user processes and a maximum of 2 GB for the system. The memory counter reaches the maximum addressable memory at 2 GB, and the ORA-04030 error will occur.

  • How do oracle stack increase ?

    Hi
    while expdp the database i got below error.
    Expdp is failing with the below errors:
    ORA-39014: One or more workers have prematurely exited.
    I found the workaround in metalink.
    Changes
    Oracle.exe stack's size was reduced to 512K from 1024K.
    Cause
    oracle.exe stack's size was reduced.
    Solution
    Increase the stack size for oracle.exe.
    Workaround:
    Perform the datapump export from other server having more stack size for oracle.exe.
    how do increate oracle stack ?

  • How do I access the web utility with model cisco sf302-08p ?

    Hi,i have a problem with the model Cisco SB SF302-08PP Switch , i connect a cable rj45 to my pc and configure the adapter local area connection (ip address:192.168.1.252), the LEDs blink green, and go to the address bar and get the IP by default, which according to the manual is 192.168.1.254 and the result is: page not found. Is there any way to change the web utility? How do I access the web utility?

    restore  the switch by holding more than 30 seconds and try accessing with ip 192.168.1.254. username and password is "cisco". before change your base ip to 192.168.1.2-253.try to ping and check the connectivity

  • RBACx Encrypted Password Change Utility

    Hi all,
    In the OIA/SRM installation guide, there is a reference to a tool, to find out the password of rbacxservice.
    "Oracle Identity Analytics utilizes an encrypted password when communicating with the database.
    To change the default database password, use the RBACx Encrypted Password Change Utility"
    Could you please help me finding out this tool.
    Many thanks in advance.
    Warm regards,
    Manipradeep Sunku.

    The mentioned tool only encrypts the password so that you don't have to store a plain text password in the config file. It does not decrypt it. The default rbacxservice password is rbacxservice.
    The tool does not come with the OIA/SRM distribution so if you need it, you will need to contact support.

  • Studio 12.1 Performace Analyzer 7.7 problem, with 'er_print' utility.

    I am having a minor but nagging problem with a regression in the ‘er_print’ utility of the Sun Performance Analyzer suite bundled in Studio 12. is there maybe a patch available or in the works?
    I have not had any success in finding a resolution by searching the open literature…
    The issue is that the ‘callers-callees’ listing only dumps functions in alphabetical order, ignoring the sort order specified by ‘sort’. This is a regression from the Performance Analyzer (7.4) behavior from Sun Studio 10. We only recently jumped to studio 12.1.
    This functionality is documented here: http://docs.sun.com/app/docs/doc/821-0304/afaid?a=view (as well as many other references). To quote:
    “callers-callees
    Print the callers-callees panel for each of the functions, in the order specified by the function sort metric (sort)."
    I use a script input to er_print that in the past analyzed the top ‘N’ functions sorted on inclusive thread time. Now I have to be sure to dump ALL functions and need a third-party search tool to find that information in the resulting report.
    Has anyone heard of this problem or are there Performance Analyzer patch(es) available. I saw some for 7.6 and another for unspecified but have not seen this problem in patch notices.
    Thanks.
    Regards,
    Steve

    Nik, thanks for taking a look. We can't go to 12.2 because we're a software developer and we'll lose our binary compatibility with the release we've been building for the last few months. I'm a systems guy and will paste in a developer's example below.
    Note Marc's url shows a 12.1 Performance Analyzer patch 142369-01 we have not yet installed. The patch notice description doesn't show much. I'll pass on patch info to remote user/developer.
    Developer example:
    I use a script input to er_print that in the past analyzed the top ‘N’ functions sorted on inclusive thread time. Now I have to be sure to dump ALL functions and need a third-party search tool to find that information in the resulting report.
    Here’s a shortened (only 4) example of the behavior I’m seeing… the focus of the functions in callers-callees are NOT those of the functions determined by the sort metric.

  • USB Enhanced Performanc​e Keyboard utility crash

    USB Enhanced Performance Keyboard (Wired) : skd881x daemon has stopped working
    What I'm getting here is a consistent crash of the OSD / button management daemon (Skdaemon.exe) on a standard french Vista 32bit install. This might be a duplicate of this unresolved problem, although the OS is 32 bit here.
    I can reproduce the crash easily by using either one of the Volume+, Volume- or Mute buttons at any time as long as the Play/Pause button has never been pressed before. If I start the daemon, choose "Play/Pause" (the indication "Play/Pause" appears in the OSD), then the instance of the daemon will never crash afterwards and I will be able to use the volume buttons until the next reboot.
    I have tried :
    using the keyboard configuration tool to change most of the settings,
    clean uninstalling/reinstalling the (latest) driver and utility,
    looking up for a solution elsewhere,
    to no avail.
    I would appreciate any pointer to resolve that annoying problem.
    EDIT : updated the title so it appears more explicit from the forum view

    I know that bumping my own thread is not really a display of gentleman's manners, but I would like to know if there is a way to reach lenovo directly, at least to make the company aware of this annoying bug (which does seem to be recurrent). I can't seem to find it as I'm lost in the endless cross-references between lenovo and IBM support pages, and a part of the online support doesn't seem to be available in France

  • Error while deploying a web service whose return type is java.util.Date

    Hi
    I have written a simple web service which takes in a date input (java.util.Date) and returns the same date back to the client.
    public interface Ping extends Remote
    * A simple method that pings the server to test the webservice.
    * It sends a datetime to the server which returns the datetime.
    * @param pingDateRequest A datetime sent to the server
    * @returns The original datetime
    public Date ping(Date pingDateRequest) throws RemoteException;
    The generation of the Web service related files goes smoothly in JDeveloper 10g. The problem arises when I try to deploy this web service on the Oracle 10g (10.0.3) OC4J standalone. it gives me the following error on the OC4J console :
    E:\Oracle\oc4j1003\j2ee\home\application-deployments\Sachin-TradingEngineWS-WS\
    WebServices\com\sachin\tradeengine\ws\Ping_Tie.java:57: ping(java.util.Date) in com.sachin.tradeengine.ws.Ping cannot be applied to (java.util.Calendar) _result  = ((com.sachin.tradeengine.ws.Ping) getTarget()).ping
    (myPing_Type.getDate_1());

    I read somewhere that the conversion between java to xml datatype and vice versa fails for java.util.Date, so it is better to use java.util.Calendar. When I change the code to return a java.util.Calendar then the JDeveloper prompts me the following failure:
    Method Ping: the following parameter types do not have an XML Schema mapping and/or serializer specified : java.util.Calendar.
    This forces me to return a String data.
    I would appreciate if someone can help me out.
    Thanks

    Hi
    I got the web service working with some work around. But I am not sure it this approach would be right and good.
    I started altogether afresh. I did the following step :
    1. Created an Interface (Ping.java) for use in web Service as follows :
    public interface Ping extends Remote{
    public java.util.Date ping(java.util.Date pingDateRequest)
    throws RemoteException;
    2. Implemented the above interface in PingImpl.java as follows :
    public class PingImpl implements Ping
    public java.util.Date ping(java.util.Date pingDateRequest) throws RemoteException {
    System.out.println("PingImpl: ping() return datetime = " + pingDateRequest.toString());
    return pingDateRequest;
    3. Compiled the above 2 java files.
    4. Generated a Stateless Java Web Service with the help of JDeveloper. This time the generation was sucessful.(If I had "java.util.Calendar" in place of "java.util.Date" in the java code of the above mentioned files the web service generation would prompt me for error)
    5. After the generation of Web Service, I made modification to the Ping interface and its implementing class. In both the files I replaced "java.util.Date" with "java.util.Calendar". The modified java will look as follows :
    Ping.Java
    =========
    public interface Ping extends Remote{
    public java.util.Calendar ping(java.util.Calendar pingDateRequest)
    throws RemoteException;
    PingImpl.Java
    ================
    public class PingImpl implements Ping
    public java.util.Calendar ping(java.util.Calendar pingDateRequest) throws RemoteException {
    System.out.println("PingImpl: ping() return datetime = " + pingDateRequest.toString());
    return pingDateRequest;
    6. Now I recompile both the java files.
    7. Withour regenerating the Web Service I deploy the Web Service on OC4j 10.0.3 from JDeveloper. This time the deployment was sucessful.(The Deployment fails if I don't follow the step 5.)
    8. Now I generated a Stub from JDeveloper and accessed the stub from a client. It works fine. Here if you see the Stub code it takes java.util.Date as a parameter and returns a java.util.Date. (Mind you I am accepting a java.util.Calendar and returning the same in my Web Service interface. Step 5)
    The confusing thing is the Serialization and Deserialization of Data from Client java data to Soap message and Soap message to Server java data.
    From Client to SOAP :
    java.util.Date to datetime
    From SOAP to Server :
    datetime to java.util.Calendar
    From Server to SOAP :
    java.util.Calendar to datetime
    From SOAP to Client :
    datetime to java.util.Date (I am not able to understand this part of the conversion)
    Any help or inputs would be appreciated.
    Thanks

  • I have 3 older ext. hard drives that I've utilized many times. Today while searching for old files, one of the three is no longer recognized by my PowerMac.  Any suggestions?

    I have 3 older ext. hard drives that I've utilized many times. Today while searching for old files, one of the three is no longer recognized by my PowerMac. The drive is not listed in Disk Utility.  Any suggestions?

    Is the computer in you equipment line:
    Dual Core Intel Xenon
    (which is not a PowerMac but a Mac Pro) the one you are asking about, or do you have an older PowerMac?
    If a Mac Pro, their forums are here:
    Mac Pro
    and, as Mac Pros have a totally different architecture from the pre-2005 Macs this forum covers, you may not have the same issues that can affect the older models. If someone didn't notice your equipment line, you could get advice that doesn't apply.
    If you really have a pre-2005 PowerMac, read on.
    If the stubborn external is USB and does not have its own power brick (i.e., it gets power only from the computer's UBS ports--"bus powered"), it may not be getting enough power. As electric motors age, they can demand more power than when new, and the power available on any USB port is limited.
    The typical workabouts to making a computer recognize an aging, bus-powered USB drive are:
    Get a powered USB hub (has its own power brick
    Get a "Y" USB cable: 1 Meter USB 2.0 A to 5 Pin Mini B Cable - Auxiliary USB "Y" Power Design for external hard drives.
    The second gets power from two USB ports on the computer and often that's enough.
    Remember that the USB ports on your keyboard seldom provide enough power even for a thumb drive, so be sure to use the USB ports on the back of the computer.

  • After port forward, airport utility can no longer see my time capsule

    I tried to forward public port 1025 to private port 80 on a raspberry pi using  airport utility. But after I did that,  the airport utility can no longer see my time capsule. Wifi still works correctly. Are there any conflicts about port 1025? How to fix that other than resetting the time capsule?
    Thanks,
    Michael

    It doesn't sound like a port that is used.
    From the standard google search.. nope.
    Reboot the whole network..
    No luck tell me what OS version you are running the utility on and what model and firmware TC???
    Note with Yosemite, anything can and will happen.

  • I have a PowerMac G4 running ProTools that no longer boots up.  All I get is a file folder on the screen with a flashing question mark in it.  Ran the Utility disk and all systems passed.  Any ideas?

    You need to use the computer's install disks to repair the hard drive or install a new OS.

  • IPod not recognized by iTunes & Disk Utility - Recognized by System Profile

    I have a 40GB iPod Clickwheel (4th Gen?) that i'm trying to fix back to life since my mini was just stolen and i'm out on the road on tour all the time. my iPod actually powers up by itself just fine, the battery life is just peachy, and it can run independently without songs (i'm able to look around just as though i had songs on there - i can play games, alter settings, etc etc.).
    However, there's a few things i've noticed!
    When i go to the iPod's about menu (when disconnected from the computer), it shows there's no songs, that there's 0 capacity, 0 available - shows that the version is 3.1.1, the serial and model numbers, but the format is unknown.
    I've tried plugging the dang thing into my computer to much avail - IF iTunes recognizes it, it says it needs to be restored -- GREAT! so i try to restore the iPod, however, i almost instantly get an error: The iPod cannot be restored because it is currently busy. When i clicked the help tag, it says it's a common problem in iTunes 7.0 - great, i have 8.0.2; and i've tried running everything from a restart on the ipod to a restart on the computer, updating all my system files, running the iPod in disk mode, etc, but nothing seems to make it want to restore.
    when i look in system profiler; it shows that the iPod is hooked up to my USB port (which is just fine, and i've never had problems running a click-wheel iPod through that before); however both Disk Utility and iTunes do not acknowledge it's existence. what gives?
    is my iPod a goner? how would i go about restoring this so i can use it? I've tried it on my Power PC (Specs below) as well as trying it on an iBook and iMac; with the same results every time. i know it's not the cable, because the iPod actually charged via that cable last night!
    any help!?

    If you can get it to show up in Disk Utility, try reformatting (erasing) it in Disk Utility. If that process completes without stalling or errors, quit Disk Utility and run iTunes. Immediately attempt to do another Restore to install the iPod's software and initialize.
    If the iPod does not erase successfully (it should take less than one minute for a standard erase) in Disk Utility, the iPod's hard drive may be faulty.
