Other wait class
can anyone tell me what are the wait events in wait class 'OTHER';
Dear dbaforu,
Short but indeed useful information here;
http://download.oracle.com/docs/cd/E11882_01/server.112/e16638/instance_tune.htm#PFGRF94504
+"+
+10.3.7 events in wait class other+
+This event belong to Other wait class and typically should not occur on a system. This event is an aggregate of all other events in the Other wait class, such as latch free, and is used in the V$SESSION_EVENT and V$SERVICE_EVENT views only. In these views, the events in the Other wait class will not be maintained individually in every session. Instead, these events will be rolled up into this single event to reduce the memory used for maintaining statistics on events in the Other wait class.+

Database Time Spent Waiting (%): Wait Class Other nearly 100% all the time
Don't understand why OEM is reporting that Database Time Spent Waiting (%): Wait Class Other is nearly 100% all the time. Database 10.1.0.4 just installed on Linux(RHEL4AS) and nobody use it for now except OEM and me for admin purpose.
Any clue for that problem ?
Regards
NicolasSeems like you are not the first to see this kind of behaviour.
I've found another similar thread on metalink. I can't say the answer is terribly helpful, but thought you might be interested anyway:

Database Time Spent Waiting (%) at 100 in event class Commit
Hi everyone, yesterday we create a new database instance with dbca, the creation process was ok, and the two instances are running ok, database stops and starts without any problem, and listeners are ok. In the enterprise manager of this new instance we found this message:
Database Time Spent Waiting (%) at 100 in event class Commit, this event happend every 1 or 2 minutes sometimes at 100, the next 40%, the next 98, ... and so on.
Do you know what's happend in this instance?
Thanks in advance to everyone

From Oracle Database Reference Manual:
Commit
This wait class only comprises one wait event - wait for redo log write confirmation after a commit (that is, 'log file sync')
So you can't write fast enough into your log files.
Did you check the frequency of log switches?

Hi José! Please don't get anxious because of this: Wait time must be SOMEWHERE, there's a saying "An OLTP DB is only as fast as its redo logs", but if you are not having any performance problem you don't need to do anything special.
You say you've just created the DB. Now make it DO something: put it to the test by simulating production conditions as closely as you can, and after some hours ask the users whether there is some problem. If there is, take a look at the wait statistics... you'll probably see many other top events before this one!

Wait event "virtual circuit wait" in wait class "Network" was consuming sig
Hello,
We are facing this problem when there are 2 queries try to run at the same time.
The first query takes longer to finish so 2nd has to wait for 1st to be finished and then only 2nd starts. It seems the jam is at netowork instead of server.
I want to make sure before I start testing on network.
I get following :
Wait event "virtual circuit wait" in wait class "Network" was consuming significant database time. 98.4
Wait class "Network" was consuming significant database time.
and recommendations is stated as :
Investigate the cause for high "virtual circuit wait" waits with P1 ("circuit#") value "21" and P2 ("type") value "2".
I am checking OEM.
Thanks,
Shashi.Hello Sybrand,
Can you suggest some changes to be done to test ?

User I/O Wait class in Top 5 Timed Foreground Events
Hi Mates
In my awr report in Top 5 Timed Foreground Events, i get the below event list
Event Waits Time(s) Avg wait (ms) % DB time Wait Class
DB CPU 25,721 58.29

So does it means that there is a issue with disk I/O on my box. since the wait class is showing as User I/O.

If so then take a look at Dom Brooks comment - your average read times are in the range of 0.1 to 0.3 milliseconds - they're mostly coming out of filesystem cache (but maybe you have some very good database flashcache installed).
Your first move should probably be to take some of the memory from your file system cache and increase your buffer cache - this will probably decrease the number of reads reported and the amount of CPU used. I'd also look for statements that seem to be doing an unreasonable amount of I/O to get their end results, and check the "Segments by ... " section of the report to see which objects are seeing most I/O.
Before you mess about with ASM, you should simply check for easy ways to do less work.

Wait class 'commit' consuming significant database time.
Hi
My awr report was showing that the log file sync as the top wait event.I can also see additional message saying that wait class 'commit' consuming significant database time.Can any one suggest me what are the tuning things i need to consider for this wait class 'LOG FILE SYNC'
ThanksBe very careful about this.
Follow this only if you can afford to lose some data in case of instance failure
(eg death of the instance from a bug, server panic/reboot, power failure etc).
Oracle's normal behaviour is to guarantee that every committed transaction
IS available by ensuring that it is in the redologs and reapplying it if necessary
in case of an instance failure and recovery or media recovery.
A Commit NOWAIT means that there is a possibility, however slight, that
the last few transaction(s) might not have gotten into the redo logs at the time
of instance failure.
Your application / analysts must be able to identify transactions that are 'lost'
and reapply them after you restart a crashed instance. -
Hi,
As per documents In general, the addition of wait classes helps direct the DBA more quickly toward the root cause of performance problems.
How could i trace the root cause of performence problems if it is related to wait class?

Thanks,I am not completely sure that I understand your question. The wait class gives you an approximate idea of where the performance problem will be found. You must then further investigate the wait events in that wait class. There are of course potential problems with starting at the wait class (some wait classes have 2 wait events, while others have many - that could throw off the search for the problem that is impacting performance the most), but at least it provides a starting point. To give you an idea of the wait events in each wait class, here is a SQL statement that was executed on Oracle Database 11.1.0.7:

what is Wait class Application?
give guide meHi,
Application is one of a classification of Wait class events along with network,commit,idle,user i/o.
Application: locks waits caused by row level locking or explicit lock commands
Have a look into this link.

How can I compile and run other java classes from within an application?
Hello there everyone! I really hope that someone can help me. I am writing a program that must be able to compile and run other java classes that are in different files, much like development environments like Kawa or Forte allow you to do.
There has to be a way of doing this ( I hope!! ), but i can't seem to find it!!
I have tried using this command to compile:
Runtime.getRuntime().exec ("c:\\programs\\javac className.java");
...and this one to run:
Runtime.getRuntime().exec ("c:\\programs\\java className");
...but neither works!!! I can compile and run classes that are in the same file as my application, but I can't get it to work at all for files in different directories or files.
PLEASE, PLEASE, PLEASE help me - i've run out of ideas, and i need this to be working in 3 days!!!
Thank you very much for any help anyone can give me, I really appreciate it!! Thanks again!!
Adrian ( ...in distress!! )public class JavaCompiler{
public static void main(String[] args)throws Exception{ //sorry bout the laziness
if(args == null || args.length != 1){
System.out.println("Usage: java JavaCompiler MyClass.java");
System.exit(0);
String className = args[0];
Runtime rt = Runtime.getRuntime();
Process p = rt.exec("javac " + className); //consider setting cpath for this
p.waitFor();
//now try to run after it is done.
p = rt.exec("java " + className.substring(0, (className.length() - ".java".length()));
p.waitFor();
//do some other stuff
}This should get you going. You may consider looking into the System.getProperty() method in order to determine the type of OS it is running on in order to findo out what command to run. I know that the sun tool listed above is nice, but by my understanding the sun tools provided are not guaranteed to stay the same. I'm no expert on this matter, but that is one of the reasons there is no API documentation for those tools. Also, I don't believe those tools come packaged with the JRE. (Of course if you are making an IDE it will be expected that the user has an sdk installed. Good luck with figuring this thing out. -
Child-class refering to other Child-classes
Hello!
I am an inexperienced Java-programmer who have recently given the following some thought: if I have a Parent class that creates an instance of another class, and that class, in turn, needs to refer back to a sibling instance in the Parent class, what is the best way to go?
I can see possibilities with creating a static method in Parent, that returns a reference to whatever other child class you might need to access. Also, I guess you could send the Parent-class to the child class as an argument, and save it in a reference-variable to use when you need to use one of the Parents non-static methods. Probably there are more possible ways.
But what I'm asking is; which way is the most "legitime" when it comes to OOP? Surely it's butt-ugly to have a load of static methods in a Parent-class, or to propagate the Parent class through levels and levels of childs and grand-childs.
If I haven't made myself clear -- I have doubts about my English :P -- I'll try to illustrate my question with a short code-snippet below
Class Parent
Child myChild;
Sibling mySibling;
public Parent()
myChild = new Child();
mySibling = new Sibling();
// ... more follows
Class Child
public Child()
// Here, I want to somehow access "mySibling" in class Parent
// ... more follows
// ... more follows
Class Sibling
// ... more follows
}As I tried to illustrate with my code snippet, the children are of separate classes. I could yet again clarify my point by giving a more concrete example, one that's the actual cause of my question.
I have a class [MainClass] that extends JFrame, implements MouseListener, and calls its own constructor in a main()-method.
The constructor then goes about creating the Frame's interior by creating instances of JPanels and, in one case, an extenden JPanel called CardPanel (implements ActionListener). So now we have three JPanels (including the extended) active:
JPanel cardPanelButtons; // is the topmost panel in the frame, and lets the user switch between the different cards in the CardPanel. It contains three buttons that are in a ButtonGroup to make sure only one of them is pressed at any one time.
CardPanel cardPanel; // is centered in the frame, and contains every interactive item in the application, except for the buttons in the cardPanelButtons-JPanel
JPanel statusPanel; // contains a non editable JTextArea for status-messages
CardPanel creates three panels in its constructor, and adds these to itself.
In one of these panels (that are selected by the user, clicking on the buttons in the cardPanelButtons-JPanel) there is a "Search"-button that when pressed, performs a Database-search and then pops up the next card in the CardPanel with the apropiate query result filled in and displayed. This is all good, however for GUI-purposes, this action requires the apropiate button in the cardPanelButtons-JPanel to be "pushed" automatically when this switch between cards take place. Since these buttons are unknown to CardPanel, it needs to somehow reach them, which is where I'm starting to wonder what the best way around this is.
Should I have the CardPanel-constructor take the parent class as an argument, and access the buttonGroup by a public getter-method in MainClass. Or should I static a public getter-method in the MainClass, letting me ignore to pass on the MainClass for reference. Should I ignore extending JPanel to create CardPanel altogether, and add everything straight into the JFrame from a MainClass-method?
What is the most correct way, or the way programmers usually go about this type of problem?
(In order to make myself perfectly clear, this reply is quite extensive. I apologize if I got a bit carried away..) -
So I have a query that is running with a large number of CXPacket waits. There are no other tasks in the sys.dm_os_waiting_tasks that are blocking this session id with a wait other than CXPacket Wait. This is taking place on a SQL Server 2008
R2 machine. My question is there something else to look at? I've gone ahead and posted the output of the entire sys.dm_os_waiting_tasks. Any thoughts?

First, I would take a look at what your MAXDOP setting is, that's seems a bit high unless you have around 80 processors - stick to multiples of the number of processors in a single numa node and don't go over half of the numa nodes if this is for an OLTP
system. If it's for a DSS or DW system then having a very high maxdop should be fine.
When dealing with CXPACKET the wait means that it's waiting for all of the parallel threads to complete before it can merge the results and move on. If any single thread has to process more than any other (or waits longer for data) the whole process has
to wait. I would investigate to see if there is a large skew in statistics and one thread is processing much more than another. I'd also try creating an extended events session to grab all of the waitinfo for that session.

JAXB: How to have my generated classes subclass some other outside class ?
With my XJS and DTD, JAXB generates the following:
public class FraisMessage
extends MarshallableRootElement
implements RootElement
{ etc...I would like it to generate this instead:
public class FraisMessage extends MyOtherClass
extends MarshallableRootElement
implements RootElement
{ etc...MyOtherClass is another class outside the scope of JAXB
How do I do this ? What do I have to put in my XJS to get this ?You cannot do that. TheJAVA language does not allow a class to "extend" more than one upper class.
Typically, the solution is to modify your architecture a little bit. Just use the "has a" relationship instead of "is a". That means something like that:public class MyFraisMessage
extends MyOtherClass
private FraisMessage message;
etc...You write an extension "MyFraisMessage" of your upper class "MyOtherClass", which has the JAXB generated object as an attribute. This structure is often useful, when you think you would need multiple inheritance. -
Instantiation access to other java classes
Hello,
I have a public Java file in my package.
I want to grant access to only classes of my choice to instantiate my class, irrespective of any package(my constructor is public itself).
Is there any way?
eg:
I have MyJava.java in com.abc;
I want to give access only to 2 classes even though other classes exist in the same package:
YourJava1.java in com.abc; (there are other classes in this package)
YourJava2.java in com.xyz; (there are other classes in this package)
Thanks.Hi,
I'm not sure about your depths in java knowledge... however, I'm gonna try to help you based on my knowledge...
whenever "public" modifier will be used any case( doesn't matter if it is Class, method or attributes), it will be visible from any package level. That is the Rule. If you make your constructor as public, then it always be accessible for any class regardless the package level. Otherwise, it would defeat the purpose of "public" modifier.
Its depends on your business logic why you are trying to do this scenario. But, there are couple of ways to solve the problem...
Make "MyJava.java"constructor as "protected" AND move whichever class needs to have handle on it into the same package(in this case: "YourJava1.java" and "YourJava2.java"). Thats how only those classes will be able to instantiate "MyJava.java". you may have multiple constructor and one of them can be "public" so that this object also can be accessed from outside of the package...
Another option might be - make "MyJava.java" as an Interface or an abstract class. So that you can implement it whichever class needs it. This is how you can restrict it someway...
Hope it helps... -
Is connecting my ipod to other computer classed as an availabilty
I heard that an Ipod touch can only have 5 computer availabilty on 5 computers. I only three computers, and my Ipod said that i used up all of my 5. i am getting worried that i have used up all of them, by conntectingmy Ipod to some computers at college for only charging purposes. So i am worried that since i have conntectedmy Ipod to those computers, that it has classed that as an availabilty
The number 5 is referring to the number of computers you have authorized to play and sync your iTunes purchased content. If you have reached the limit of 5, you can try to deauthorize some of those other machines if you still have physical access to them by choosing Store -> Deauthorize this Computer in iTunes.
Otherwise, you'll have to use the deauthorize all option as described in this document.

Oracle forms classes don't work with some others signed classes
Using formserver6i patchset11 with JInitiator 1.3.1.9
I've re-signed f60all_jinit.jar with my own identity...if I try to use some other signed PJC,the form doesn't start(.. is blocking)...Does someone knows why this is happening...the PJC's worked with JInitiator 1.17.*...I've resigned f60_all.jar and now all the forms works fine...but I still have some doubts about the parameters in formsweb.cfg...here my formsweb.cfg has:
archive_jini=f60all_sandu.jar,testtooltip.jar,Host.jar
archive_ie=f60all_sandu.jar
At this moment,Jinitiator doesn't downloads f60_jinit.jar...and all works fine..What's the differnce betwen archive_jini and archive_ie?
What's the differnce betwen f60_jinit.jar,and f60all.jar?
Replacing f60_jinit.jar with f60all will cause any problems?
