10.2.0.3 to 10.2.0.4 upgrade-Real Application cluster Component INVALID

HI Guys just upgraded the standalone database from 10.2.0.3 to 10.2.0.4 ...Everything looks good after running the catupgrd.sql
except the Real Application Cluster Component is INVALID..
Is it because its not a RAC database or some other reason?Plz help
SQL> SELECT COMP_NAME, VERSION, STATUS FROM SYS.DBA_REGISTRY;
COMP_NAME
VERSION STATUS
Oracle Database Catalog Views
10.2.0.4.0 VALID

Oracle Real Application Clusters
10.2.0.4.0 INVALID

This is "normal" if you are not using RAC - see MOS Doc 312071.1 (RAC Option Invalid After Migration)

  • A problem with threads

    I am trying to implement some kind of a server listening for requests. The listener part of the app, is a daemon thread that listens for connections and instantiates a handling daemon thread once it gets some. However, my problem is that i must be able to kill the listening thread at the user's will (say via a sto button). I have done this via the Sun's proposed way, by testing a boolean flag in the loop, which is set to false when i wish to kill the thread. The problem with this thing is the following...
    Once the thread starts excecuting, it will test the flag, find it true and enter the loop. At some point it will LOCK on the server socket waiting for connection. Unless some client actually connects, it will keep on listening indefinatelly whithought ever bothering to check for the flag again (no matter how many times you set the damn thing to false).
    My question is this: Is there any real, non-theoretical, applied way to stop thread in java safely?
    Thank you in advance,
    Lefty

    This was one solution from the socket programming forum, have you tried this??
    public Thread MyThread extends Thread{
         boolean active = true;          
         public void run(){
              ss.setSoTimeout(90);               
              while (active){                   
                   try{                       
                        serverSocket = ss.accept();
                   catch (SocketTimeoutException ste){
                   // do nothing                   
         // interrupt thread           
         public void deactivate(){               
              active = false;
              // you gotta sleep for a time longer than the               
              // accept() timeout to make sure that timeout is finished.               
              try{
                   sleep(91);               
              }catch (InterruptedException ie){            
              interrupt();

  • Problem with threads running javaw

    Hi,
    Having a problem with multi thread programming using client server sockets. The program works find when starting the the application in a console using java muti.java , but when using javaw multi.java the program doesnt die and have to kill it in the task manager. The program doesnt display any of my gui error messages either when the server disconnect the client. all works find in a console. any advice on this as I havent been able to understand why this is happening? any comment would be appreciated.
    troy.

    troy,
    Try and post a minimum code sample of your app which
    does not work.
    When using javaw, make sure you redirect the standard
    error and standard output streams to file.
    Graeme.Hi Graeme,
    I dont understand what you mean by redirection to file? some of my code below.
    The code works fine under a console, code is supposed to exit when the client (the other server )disconnects. the problem is that but the clientworker side of the code still works. which under console it doesnt.

    That one's from a book. I used that code to start with my applet. Mine calls different merthod from the switch cases. Say I have:

      /* something here */
    drawMain(g);
    public void drawMain(graphics g){
    g.drawString("test", x, y);
    //here's where i'm trying to pause
    //i've tried placing Thread.sleep between these lines
    g.drawLine(x, y, a, b);
    //Thread.sleep here
    g.drawRect(x, y, 50, 70);
    }I also need to put delays between method calls but I need to synchronize them. Am I doing it all wrong? The application pauses or sleeps but afterwards, it still drew everything all at once. Thanks a lot!

    It is. Sorry about that. Just answer any if you want to. I'd appreciate your help. Sorry again if it caused you anything or whatever. .n_n.

  • Problem with threads communication

    Hi All
    I have a multithreaded application in which I have 3 threads running including main thread. One of the thread (Thread1) spawned by main thread is performing the business logic required. The other one (Thread 2) is just to send the periodic signals to an admin application that it is alive. Now I need to pass some data obtained from business logic (Thread1) to the second thread (Thread2). How can i do that.? I need the data from Thread1 to Thread2 every time, the thread2 send the alive request to admin application.
    Thanks & Regards
    Inder Jeet Singh

    See Producer/Consumer example at for 2 threads exchanging data:
    http://java.sun.com/docs/books/tutorial/essential/threads/synchronization.html
    In your case it seems reasonable to store data somewhere until T2 will use it during sending
    alive request to admin application

  • Problem with threads hanging

    We have a problem where our application stops responding after a few days of usage. Things will for fine for a day or two, and then pretty quickly threads will start getting hung up, usually in places where they are allocating memory
    We are running WebLogic 8.1 SP2 on Sun JDK 1.4.2_04 on Solaris 8 using the alternate threading model and the -server hotspot vm. We are running pretty much the same code that we had no problems with under WebLogic 6.1 SP4 and Sun JDK 1.3.1.
    A thread dump usually shows that some or all of our execute threads are in the state "waiting for monitor entry" even though they are not currently waiting on any java locks. Here is a sample thread from the thread dump (we have ~120 threads so I don't want to post the full dump).

    We've done a pstack on this process when it's in this state, and the threads that are in the "waiting for monitor entry" that look like they're allocating memory are all waiting on the same lwp_mutex_lock with some allocation method that's calling into the native TwoGenerationCollectorPolicy.mem_allocate_work (see pstack output below for the same thread as in the thread dump above)

    Has anyone ever seen anything like this? I'm trying to figure out if this is caused by something we're doing, or something relating to our environment and jvm options. Any ideas?

    Thanks for the reply - I'm testing our app with the +UseConcMarkSweepGC now in our test environment to make sure it doesn't cause any problems there.  Unfortunately the only place we've had this problem is on the production server, so it's extra difficult debugging this. 
    We're using the following memory options:
    -ms512m -mx512m -XX:NewSize=128m -XX:PermSize=192m -XX:MaxNewSize=128m -XX:MaxPermSize=192m -XX:SurvivorRatio=8and the following debugging options, as we've also been seeing OutOfMemoryErrors ( see http://forum.java.sun.com/thread.jsp?forum=37&thread=522354&tstart=45&trange=15 )
    -verbosegc -XX:+PrintGCDetails -XX:+PrintGCTimeStamps -XX:+PrintHeapAtGCBTW, which c++filt version and options are you using? Our Solaris boxes only seem to have the GNU version installed. I was trying to run that on some of the other stack traces and wasn't getting anywhere, and didn't know if because it was GNU version wouldn't work on something compiled with the Sun compiler.
    Thanks!

  • Problem with threads in my swing application

    Hi,
    I have some problem in running my swing app. Thre problem is related to threads.
    What i am developing, is a gui framework where i can add different pluggable components to the framework.
    The framework is working fine, but when i press the close action then the gui should close down the present component which is active. The close action is of the framework and the component has the responsibility of checking if it's work is saved or not and hence to throw a message for saving the work, therefore, what i have done is that i call the close method for the component in a separate thread and from my main thread i call the join method for the component's thread.But after join the whole gui hangs.
    I think after the join method even the GUI thread , which is started for every gui, also waits for the component's thread to finish but the component thread can't finish because the gui thread is also waiting for the component to finish. This creates a deadlock situation.
    I dont know wht's happening it's purely my guess.
    One more thing. Why i am calling the component through a different thread, is because , if the component's work is not saved by the user then it must throw a message to save the work. If i continue this message throwing in my main thread only then the main thread doesnt wait for user press of the yes no or cancel button for saving the work . It immediately progresses to the next statement.
    Can anybody help me get out of this?

  • Problem with threads and/or memory

    I'm developing an application where there are 3 threads. One of them sends a request to the other, and if the 2nd can't answer it, it sends it to the 3rd (similar to CPU -> CACHE -> MEMORY). When i run the program with 1000-10.000 requests, no problem occurs. When i run it with 300.000-1.000.000 requests, it sometimes hangs. Is this a problem with the garbage collector, or should it be related to the threads mecanism.
    (note: eache thread is in execution using a finite state machine)

    i had been running the program inside Netbeans.
    Running the jar using the command line outside
    Netbeans i have no more problems... Does Netbeans use
    it's own JVM?Depends how you set it up, but look under the options. There are settings for the compiler and jvm that it uses.

  • Default Encrypted  Password

    Dear All,
    i want to insert encrypted Password of 'password' string into table user_dtl column PASSWORD .
    How can i insert Encripted password into table.
    Thanks

    Hi Vedant,
    See the CUSTOM_HASH function that is installed with sample application in the APEX.
    Here is the code for it:
    create or replace function custom_hash (p_username in varchar2, p_password in varchar2)
    return varchar2
    is
      l_password varchar2(4000);
      l_salt varchar2(4000) := 'XFSPL28ZTWEWWM6FHWMK68AG5NQVLU';
    begin
    -- This function should be wrapped, as the hash algorithm is exposed here.
    -- You can change the value of l_salt or the method of which to call the
    -- DBMS_OBFUSCATOIN toolkit, but you much reset all of your passwords
    -- if you choose to do this.
    l_password := utl_raw.cast_to_raw(dbms_obfuscation_toolkit.md5
      (input_string => p_password || substr(l_salt,10,13) || p_username ||
        substr(l_salt, 4,10)));
    return l_password;
    end;
    i want to insert encrypted Password of 'password' string into table user_dtl column PASSWORD.The above function will give the encrypted password which can be inserted into USER_DTL as follows:
    INSERT INTO USER_DTL(USERNAME,PASSWORD) VALUES(:P1_USERNAME, CUSTOM_HASH(:P1_USERNAME,:P1_PASSWORD))Be sure that PASSWORD column in USER_DTL is of type VARCHAR2 and of adequate length as to accommodate the encrypted password.
    Hope it helps!

  • Delete File From Mounted Volume

    Hey,
    I am trying to delete the "Calendar Cache" files on both my laptop PowerBook G4 and the Mac Pro Quad that I sync my calendars with. I am using ChronoSync and the individual calendars sync fine, but there is a little house keeping needed with the cache file. They need to be deleted on both systems in order to "refresh" the views of the calendars.
    So after the sync of calendars, I have the software initiating an AppleScript that deletes both. Here's the script:
    +(* PowerBook Files / delete cache file *)+
    +(* Please note that both systems have the same username. This may be arise a conflict *)+
    +tell application "Finder"+
    + activate+
    + tell application "Finder" to delete file "Calendar Cache" of folder "Calendars" of folder "Library" of disk "useranthony"+
    +end tell+
    +(* Mac Pro Quad/ delete cache file *)+
    +tell application "Finder"+
    + mount volume "afp://10.10.10.1/anthonyabraira"+
    + tell application "Finder" to delete file "Calendar Cache" of folder "Calendars" of folder "Library" of disk "/volumes/useranthony"+
    +end tell+
    I am having trouble addressing a deletion on the networked Mac Pro Quad.

    why send it to the trash — just delete it...
    (* PowerBook Files / delete cache file )
    try
            do shell script "rm -rf /Library/Calendars/Calendar\\ Cache"
    end try
    you may need a delay for the Mac Pro Quad to mount
    ( Mac Pro Quad/ delete cache file *)
    --the mount and then the delay
    delay 4
    try
            do shell script "rm -rf /THE-CORRECT/PATH-HERE/Library/Calendars/Calendar\\ Cache"
    end try

  • Jabber Options - Phone Accounts - Voicemail -- "Spinning Wheel"

    Been trying to resolve a nagging issue.   We currently have CUCM 8.6.2-20000-2, CUPS 8.6.4-10000-28 and just put up Unity Conn 9.1.  Jabber Win clients are 9.2(1).   Several people have not been able to integrate voicemail into the Jabber client.  
    We are totally MS AD integrated.   In CUPS, I had Applications -> Cisco Jabber -> Settiings  Credentials Used For Voicemail service set to CUPS so the user would not need to supply credentials.  To help me debug, I went and changed this setting to "Not Set" so that the Phone Accounts option appears in Jabber 4 Win client. 
    So far all the people who do not work access the Phone Accounts setting in the Jabber client see the "Spinning Wheel".   They can't see the fields to enter their AD creds and the voicemail server.   Reinstall of the client does not seem to help.  There seemed to be a bug that described this but I think it was fixed in 9.1(2).  You can't display the Bug description because it contains proprietary info. 
    I have attached a screen shot of my Jabber Client Phone Account -- when I enter the credentials, I log in fine.
    Anyone seen this or know how to fix? 
    TIA --- Perry

    Well, I had TAC look at this issue. Short story is that it was an issue with one of the *many* local cache files which hid the real source of the problem.  I actually had the Mailstore misconfgured in CUPS.  I used the Exchange server's CAS IP instead of Unity Connection.   We created new Mailstore definition that used the Unity Conn IP's, created a new Voicemail Profile and associated the user to that profile.   She worked....
    I deleted my all my Jabber for Windows local cache files and I then received the "spining wheel" issue.  I moved my ID to the new Voicemail Profile with correct Mailstore and I could connect fine.   TAC spent an hour pouring through files on my PC and could not find the reason why my ID was working.   TAC indicates that in 9.x, a lot of this configuration moves to CUCM and hopefully cuts down on these issues!  PRT files from the Jabber client really did not assist them in locating the problem.
    Hope this helps....

  • Collaborate on Excel workbooks with Sharepoint Foundation

    My company recently implemented SharePoint Foundation 2013 and our shared Excel workbooks are no longer allowing multiple users to collaborate at the same time. We have verified that all the settings and permissions are correct and that checking in and
    checking out is not required. Is this something that is not available with SharePoint Foundation? We are using Office 2013 installed on the clients, not Office online. Thank you.

    Co-authoring of Excel workbooks is only supported when all the editors are using the Excel web application, not the Excel client application.
    From
    Microsoft's overview of co-authoring in SharePoint 2013:
    >"Co-authoring is easy to use from the end user’s point of view. When a user wants to work on a document in Word 2013, PowerPoint 2013, OneNote 2013, Visio 2013 or one of the Office Web Apps, he or she merely opens it from SharePoint 2013 or SharePoint
    Online, as usual. If another user already has the document open, both users can edit the document at the same time.
    One exception to this is that users can co-author in Excel Web App only if everyone uses the Excel Web App to access the workbook. If anyone uses Excel 2013 or Excel 2010 (the client application)
    to access the workbook, co-authoring in Excel Web App will be disabled for that workbook while it is open in the client application."
    >"The Excel 2013 client application does not support co-authoring workbooks in SharePoint 2013 or SharePoint Online. But, the Excel client application uses the Shared Workbook feature to support non-real-time co-authoring workbooks that are stored
    locally or on network (UNC) paths."

  • Previewing loops

    Have had no luck with PCs trying to do music recoding so I swithced over to Mac because I heard it so easy, seamless, and problem free. Now, on opening Garageband for the first time and trying to preview loops I get an error mesage that says: "the software instrument or apple loop selected is currently being installed. You have already initiated the installation of additional content for Garageband via Software update. For additional information please open the software update application." I have opened this application and nothing. I have now spent about two hours trying to fix this problem. Should I "convert back to PC, take this load of crap back to the store or is there something simple I am missing?

    I have found if you wait long enough, you will hear the file begin to play. Sometimes the delay can several seconds. Not acceptable IMO.
