Flush back utility
Hi experts,
can flushback utility revert database back to any point of time? or it is related with automatic undo management statistics like.. UNDO_RETENSION initialization parameter?
Regards,
SKP
can flushback utility revert database back to any point of time?<br>Yes. Flashback database is available since the 10g.<br>

My propose is:
� Log onto the server as the administrator named root.
� Create a new database named JunkDB.
� Register a new user named auser on the database named JunkDB with six different privileges and a password of drowssap.

Relationship between objects and information stored in a database
I've got a question that's pretty broad... but maybe someone can help with it.
I'm writing a couple of classes, one called "Customer" and the other "Store". Store can contain any number of customers, which it keeps in an array. A customer object has name and address fields, as well as an array of the current movies the customer has checked out. A third "Driver" class has the main method which calls the other two classes. When a new customer is created, it is put into the array in an object of store, and written to disk in a file named with the customer's ID number.
My question is, I'm not really sure how objects tie in with the actual database on the hard disk. For example, if I run the program once and add 3 customers, all three get written to disk, and exist in memory as objects. However, when I exit the program, I lose all 3 of those objects from the array of customers in the store object.
So, when I run the program a second time, the array is gone, though the customer information remains on disk. I have methods to delete/add customer objects to an object of store, but those don't do me any good without the array in memory. I thought that I could just load all data from disk, and put them back into the array, but isn't that inefficient if the database is very large? Is there a better way to deal with this?
I hope that was reasonably clear. I'd appreciate any help. Thanks.i would make the store a manager of the customer objects whose
responsibilities include read and writing the objects as well as caching
them.
here is some sample code for this.
public class Customer(){
int id;
/* the id field is the unique identifier for each Customer.
this field should probably be our primary key in our database
table. you don't have to use a number but whatever it is it
needs to be unique */
boolean updated;
public Customer(int customerId){
id = customerId;
updated = false;
public int getCustomerId(){
return id;
/* if the customer object has been changed and needs to flushed back
to the database this returns true. */
public boolean needsFlushing(){
return updated;
/* and your other methods go here... */
}and now for the Store...
public class Store{
private Customer[] cache;
public Store(){
cache = new Customer[10];
/* here i have hard coded as 10, you could change this or for more
flexibility use a Vector or such. */
/* spin through the cache and return the matching customer. if the
customer is not in the cache load it in the database. */
public Customer getCustomer(int customerId)throws SQLException{
for(int j=0;j<cache.length;j++){
if((cache[j]!=null)&&(cache[j].getCustomerId()==customerId)){
return cache[j];
Customer c = loadCustomer(customerId);
addToCache(c);
return c;
public void addCustomer(Customer c)throws SQLException{
/* adds a new (non-existing customer) */
saveCustomer(c);
addToCache(c);
public void close()throws SQLException{
/* flushes back any updated customers */
for(int j=0;j<cache.length;j++){
if((cache[j]!=null)&&(cache[j].needsFlushing())){
saveCustomer(cache[j]);
cache = null;
private Customer loadCustomer(int customerId)throws SQLException{
/* here would be code for loading a customer object from the
database that matches the customerId. */
return new Customer(customerId);//temporary
private void saveCustomer(Customer c)throws SQLException{
/* here would be the code for saving the customer c into the
database */
private void addToCache(Customer c){
/* this method adds the customer c to the cache. it may have to
to remove an older customer from the cache to do this. i leave
the algorithm for deciding this up to you */ -
MySQL and Java - getting program to work
I am setting up mysql to run sql from a Java program on my pc at home and probably biting off more than I can chew. I get these messages when executing the java program ExecuteSQL.java:

This is what I did.
I created a folder on my C: drive named MySQL.
I downloaded these two zip files form the MySQL website
* mysql-connector-java-3.0.11-stable
* mysql-4.0.18-win.zip
Installed both of these in folder MySQL.
I modified this line in the program ("ExecuteSQL" 1st pgm in chapter 17) I got from "Java Examples In a Nutshell" and compiled it into directory jwork.
String driver = "com.mysql.jdbc.driver", url = "jdbc:mysql://", user = "", password = "";
The readme file talks about putting a jar file in $JAVA_HOME/jre/lib/ext.
the word "Java_Home" (I now know) is not literally the name but represents the
name of the folder where the JDK to be used exists. So I put a copy of
mysql-connector-java-3.0.11-stable-bin.jar in folder C:\JDK14/jre/lib/ext.
Then I get a ClassNotFoundException error com.mysql.jdbc.driver.
After finding
http://forum.java.sun.com/thread.jsp?forum=31&thread=439796
and
http://forum.java.sun.com/thread.jsp?forum=31&thread=499888
and others, I copied (a second copy) the jar file to the directory where I am create my java objects.
Then I unzipped it to that directory, creating three folders that hold the unzipped objects.
I tried executing the program again. I get the messages at the top of this post.
The Manifest file is in one of the three folders unzipped to my java work directory.
In the second of the two above threads, jsalonen says:
the problem can be solved by mentioning mysql.jar in the Class-Path attribute
in the manifest of the jar file:
In this "manifest" file, there are only three lines and I added a fourth and it looks like this
(there are two, one in directory MySQL\META-INF and one in directory jwork\META-INF:
Manifest-Version: 1.0
Ant-Version: Apache Ant 1.6.1
Created-By: 1.4.0_01-b03 (Sun Microsystems Inc.)
Main-Class:jwork\ExecuteSQL
How do I "mention" mysql.jar in the class path attribute?
In the index.list file (in the directory with the manifest file, do I need to add anything to refer that "com.mysql.jdbc.driver" is the driver?
Do I need index.list in MySQL\META-INF ?
Thank you for your help. The program ExecuteSQL follows.

System.out not working on eclipse
Greetings...
I am no longer a newbie on Java, but I have been facing an issue lately that I have been unable to resolve myself, even though it seems to be something so silly.
I have been using eclipse for development, and by developing a simple "Just to practice" code I have found myself unable to use System class or any of its methods at a certain point. See the code below:
package one;
import java.util.Scanner;
public ClassOne {
public static void main (String args[]){
Scanner reader = new Scanner(System.in); /*Works just fine here*/
int x = 0;
System.out.println("Type in the number of objects expected"); /*Does not work at all, like if System was something I could not use at all. Not an identifier */
Scanner readertwo = new Scanner(System.in); /*System does not work here either*/
}Even if I rewrite the code after that, by erasing the import statement and all other System references in the code, System does not work again.
If anybody has ever faced the same issue and knows what I am doing wrong and what I can do to fix it, I'd really be grateful.
Thanks to all, and happy 2009.

VM experts, please resolve dispute re
Over in "Advanced Topics",
http://forum.java.sun.com/thread.jsp?forum=4&thread=167222
dnoyeB and I are having a spirited discussion about the mechanics of thread working copies vs. main mem's master copy. It's a very long discussion that spawned off from somebody else's simple question "When do you use volatile vs. synchronized." Our disagreement doesn't start until about message 30 or 40, but here are the main points of contention:
* dnoyeB says that a thread's working copy of a variable is by necessity on the stack, and that therefore, every time a method exits, that thread's working copies (or at least those used by the method) are flushed back to the master copy.
* I claim that this is not the case, and that one legal model is for a thread's working copy to be in a CPU's cache. I think that dnoyeB's model is unwieldy at best, and not doable at worst.
* I claim that a thread can directly access variables on the heap.
* dnoyeB claims that a thread cannot access the heap directly and must alway access variables via the stack.
Chapter 3 of the VM spec and Chapter 17 of the JLS are involved heavily in this discussion.
Please set us straight. :-)
Thanks,
JeffI am beginning to think we were both right and wrong.I disagree. See below for why.
1. the only thread local copies of variables are in
the operand stack, not in a frame. This is still the
stack so method ending does flush the stack var.I am using the terminology from the JVM spec and Venners' book. When I said operand stack and thread stack I meant essentially the same thing.
void func()
obj.x +=2;
obj.x +=2;
}according to the spec
if x is not volatile, after the first add, x is still
on the operand stack, and can be used directly from
the operand stack. If x were volatile, it would have
to be written back to main mem after the first write,
and reloaded for the second.You are completely wrong. You are equating memory used for holding the stack frames (which holds: local vars, operand stack, and frame data) with thread-local memory view. obj.x can live in this thread's local memory (which holds: class and instance fields, array elements that are used by methods in this thread; they live there in-between method calls, if you want).
What you seem to be saying is that if you have a method implemented as
int getX ()
return obj.x;
}then [in your opinion] this method will automatically return the most-up-to-date, out-of-main memory value of obj.x even if x is not volatile?
If x were volatile, it would have
to be written back to main mem after the first write,
and reloaded for the second.In other words, you are saying that in the scenario
thread 1 thread 2
getX(); ...
... obj.x = new_value
getX(); ... the second getX() by thread 1 is guaranteed to see the new_value for obj.x even if it is not volatile, just because the operand value had to be popped off the operand stack in between the calls to getX()?
This is clearly incorrect. As has been stated several times already, you are incorrectly assuming that method boundaries act as memory barriers in the JMM sense. They do not.
You trying to imply that the acts of pushing and popping values to/from the operand stack are the actual events of reconciling thread-local memory with main memory. This is incorrect. If Java bytecode was designed around the usual register-only abstract architecture then where would you be? There would be no stack frames but there would still be a need for a memory reconciliation model across threads/CPUs.
Why can't you acknowledge than a thread-local memory can actually map onto the CPU's local memory and Java is the first common programming language that attempted to define a memory coherency model for a concurrent runtime? All other langugages silently assume that you inherit the memory model from the underlying hardware.

Need help restoring original track data in Match
Truly hope someone can offer advice! I know there are several threads about changes made to track data while Match is syncing don't stick, but I have a slightly different problem:
I upgraded TuneUp and without knowing it, TuneUp startet "fixing" my entire library by deleting many composers and ruining other carefully edited information
By the time I realized what was happening and shut it down, some 2.000 tracks has been wreaked havoc upon
I restored the library from Time Machine, but apparently Match had had time to sync so that the wrong edits were flushed back to my library
I have now tried several ways of fixing this:
Restoring the library and using one of Doug's scripts to add a space at the end of all track names to make "my version" the latest, but this process takes so long that it times out and by then Match has again ruined my track info
Turn off Match, restore the library, make changes to some track info for all tracks, and turn Match on again. Under this approach, Match seems to treat the cloud copy as the "original" even if I made changes to my local copy later
Restoring the library, allow Match to start syncing so that my local library is viewed as part of the Match set, then disconnect the internet connection and make track changes, turn on again and sync Match again. Still, the Match changes are flushed back to my local library
Unless there are other suggestions, I see no way out by let Match stay turned off... Anyone with better insight than me into how Match treats changes and which take priority that could help?
BjornHi,
I'm not sure this will work. I use an app, no bearing on this issue, called Ivolume which adjust the volume of the tracks. To get match to recognise volume change and that the file has been update, Ivolume adds information into comments box. My understanding is that this change allows latest file to replace the one in the cloud.
My thoughts are that you have matched turned off, restore library pre problems then add a comment for those tracks affected. Once done turn back on match. A long shot but worth considering.

OnetoOne Mapping Problem in EJB 3.0 CMP's
Hi,
Im new EJB3.0, and trying to implement onetoone mapping between two tables.
The beans are deployed successfully, but when I find an object using the EntityManager, it is throwing
java.sql.SQLException: ORA-00904: "COLUMN_NAME": invalid identifier.
When I am using the following tables and Classes,
The searching statement is as follows:
SELECT COMPANYID, COMPANYNAME, COMPANYADDR, ENAME, EMPNO FROM COMPANY WHERE ((COMPANYID = 'MUM') AND (COMPANYNAME = 'MUMBAI'))
But I want to retieve the Company Details, and Employee details individually,
Please help me to sort this out.
The script for tables is:
create table emp (empno VARCHAR2(4),ENAME VARCHAR2(10),SAL NUMBER(10,2),companyid varchar2(10) ,companyname varchar2(20),primary key(empno,ename,companyid,companyname));
create table company(companyid varchar2(10),companyname varchar2(20),companyaddr varchar2(20) not null,primary key(companyid,companyname));
ALTER TABLE EMP ADD CONSTRAINT PROJ_EMP_EMPLOYEE FOREIGN KEY (companyid,companyname) REFERENCES company(companyid,companyname);
desc company;
desc emp;
insert into company values('MUM','MUMBAI','MUMBAI BASTI');
insert into company values('CHE','CHENNAI','CHENNAI NAGAR');
insert into company values('HYD','HYDERABAD','HYDERABAD HITECH');
insert into emp values('12','GANGADHAR','2500','MUM','MUMBAI');

Thanks very much!
Gangadhar.The beans are deployed successfully, but when I find an object using the EntityManager, it is throwing
java.sql.SQLException: ORA-00904: "COLUMN_NAME": invalid identifier.
Is the EntityManager find method
find(java.lang.String entityName,
java.lang.Object primaryKey)?
@Id annotation is used for a single field primary key.
For a composite primary key use the @EmbeddedId annotation
and specify a primary key class with the @Embeddable annotation.
example:
@EmbeddedId
PKClass pkClass
@Embeddable
public PKClass {}
In the find method specify the @EmbeddedId instead of the @id.
find(entity, pkClass) -

SOAPMessage message = XmlUtil.getSOAPMessageFromString(request);
SOAPMessage response = disp.invoke(message);when my disp invokes I get following Exception which seems to as a little Problem, anyway I don�t know how to get rid of this Exception.

ERROR: JDWP Unable to get JNI 1.2 environment, jvm->GetEnv() return code = -2

return logoutRequest;
}So how can I set the Charachter set before invokikng the service.
Or how can I change the Service to accept UTF-8.
Well, I don�t know.
Any help is welcome.Hi,
I don't know if this can help you, but I had a similar problem while invoking a web service. Eventually, I found out that the server was returning an html error page, and not the expected xml answer.
That's why the client code raises such an error... It means that the MIME type of the anser is text/html (for the html page) and not the text/xml type of the 'nominal' web service answer.
You can verify this by using a proxy to intercept the http request and answer involved in this web service invocation (use Fiddler for instance). Then, you will see that the server responds by sending an html page saying that something is wrong.
Hope this helps...

Xpybutil - A python library that makes X programming easier
This library is built on top of xpyb which uses XCB. It basically makes quite a few nasty things a bit less nasty. One big example is easy access to ICCCM and EWMH properties on the root and client windows.
As a trivial example, say you want to get the current desktop name:
from xpybutil import conn, root
import xpybutil.ewmh as ewmh
names = ewmh.get_desktop_names(conn, root).reply()
desk = ewmh.get_current_desktop(conn, root).reply()
print names[desk] if desk < len(names) else desk
I've had this library sitting around for a while, and to the best of my knowledge, everything in the EWMH spec is available in the ewmh module.
I think most of the stuff in ewmh/icccm is going to be pretty accessible to anyone with some experience in Python. They are also the most complete parts of xpybutil. The rest of xpybutil focuses on making other things easier, but still may require some X knowledge. (For example, keysym.py makes grabbing keys much much easier.)
As a more useful example, here's a short script that will run in the background and make all unfocused windows slightly transparent while making the active window completely opaque (if you have a compositing manager running):
# Makes all inactive windows transparent and keeps the active window opaque.
# Range of values: 0 <= opacity <= 1
# where 1 is fully opaque and 0 is completely invisible
opacity = 0.8
import xcb
from xpybutil import conn, root
import xpybutil.event as event
import xpybutil.ewmh as ewmh
import xpybutil.util as util
conn.core.ChangeWindowAttributes(root, xcb.xproto.CW.EventMask,
[xcb.xproto.EventMask.PropertyChange])
conn.flush()
get_atom = util.get_atom
get_parent = util.get_parent_window
get_active = ewmh.get_active_window
set_opacity = ewmh.set_wm_window_opacity
def update_window_opacity():
activewin = get_active(conn, root).reply()
if not activewin:
return
for client in clients:
set_opacity(conn, get_parent(conn, client),
1 if client == activewin else opacity)
conn.flush()
def client_is_normal(client):
wtype = ewmh.get_wm_window_type(conn, client).reply()
if not wtype or wtype[0] == get_atom(conn, '_NET_WM_WINDOW_TYPE_NORMAL'):
return True
return False
clients = filter(client_is_normal, ewmh.get_client_list(conn, root).reply())
update_window_opacity()
while True:
event.read(conn, block=True)
for e in event.queue():
if not isinstance(e, xcb.xproto.PropertyNotifyEvent):
continue
aname = util.get_atom_name(conn, e.atom)
if aname == '_NET_ACTIVE_WINDOW':
update_window_opacity()
elif aname == '_NET_CLIENT_LIST':
clients = filter(client_is_normal,
ewmh.get_client_list(conn, root).reply())
I've tested this on Openbox/xcompmgr, but it should work on any window manager that decorates their windows and complies with EWMH. It would work on an EWMH compliant tiling manager with some slight modification. (i.e., removing calls to get_parent and setting the opacity directly on the client.)
The API can be found here. And both examples are in the git respository.
TODO: More examples/explanations :-) I'll do my best to answer any questions here too.
xpybutil-git in the AUR.

Thanks in advance!!!
Regards,
HieuWhat did you do to resolve this issue? It could be helpful to others. Thanks.
-
Extremely urgent !!! I like someone to takeover this project or guide me through it - I can compensate if you take it over. I have the source codes but I can't seem to compile them - what IDE can I use to get started.
View this java applet that lets users create and save an image.
I would like users to be able to save a graphic from the current java applet. Then I would like them to be able to put this graphic in one of a few templates and charge them for printing permissions.
So the program must not let the user use "view source" to get the picture or to right click and "save as."(Not very important)
What I am looking for is a new applet that will combine the images with stationary templates and to be able to charge for printing. The background images in the applet also need to be exchanged with new ones.
__________________Here are my Netbeans run / debug messages for my clients source - it says build successful but I never see a running applet or anything. Any advise please - ??? I've changed the sources file path around etc but no luck. I might have to quit this soon.

Hi Gurus,
I am in one of our clients site and visited here to see Oracle problems which they are facing.
They have recently upgraded their oracle database release to 10.2.0.3 on AIX-5.3(64bit production)
Actually speaking they have a application server residing on Linux and database resides on AIX5.3.Through tnsnames.ora they are communicating their Application server.
They are unable to authorise the records in their Live system.Resulting all the trans boundry records unable to rollback and they are even loosing the old records as well.This is a very critical situation for us now :-(
The error log showing as below

ORA-07445: exception encountered: core dump [] [] [] [] [] []
Thu Jul 19 08:25:41 2007
Technical details:
This problem is arised due to "hash table key was exceeding
"ub1maxval" on 64 bit platforms because of the increas
e in size of struct memebers.
ORA-07445 and ORA-03113 are inter linked ?
and also please advice us how should we tune the rollback segments in oracle if huge rollback is concern.
Thanks
Kiran Kumar.SDo you have any Oracle error related to rollback segment or undo tablespace ?Actually speaking we use transaction boundry in our code is as concern.When user inputting transactions if
at any point of failure, any tables,files at the application level updated within the transaction boundry should be rolled back.This is failing only at some point of time and the records which meant to be flushed back from the shared memory was not happenning.
I just wanted to convey my problem scenario to you before giving the update.
I havent got any error messages regarding roll back in my alertlogfile except below.
(FOB) flags=2 fib=70000025cb621e8 incno=0 pending i/o cnt=0
fname=/oradata/pblprod/undotbs01.dbf
fno=2 lblksz=8192 fsiz=206400
Are you using automatic undo ?Yes we are using undo_management as AUTO
What is the value of undo_retention parameter ?
Undo rentention parameter value is 900 which is too high i think. :-(
SQL> show parameter undo_retention;
NAME TYPE
VALUE
undo_retention integer
900
Do you have long running queries ? How long ?
Do you large write queries (UPDATE/INSERT/DELETE)Yes we do have.We have long running queries from application level during batch updates.The batch update we call it as
Close of Business (COB).So in COB we do have larger appends/writes/delete/truncate is as concern.
But in this case i think we have a problem with write.A longer running query may run at the maximum of 5min without any indexes created.
As a conclusion i think the problem which is ORA-03113 happenning because we have a very big undo_retention value which is 900.The UNDO_RETENTION parameter works best if the current undo tablespace has enough space fir the active transactions. If an active transaction needs undo space and the undo tablespace does not have any free space, then the system will start reusing undo space that would have been retained. This may cause long queries to fail.
My thinking makes sense ?
If i am speaking sense then shall we clear the undo tablespace please ? -
N97 restarts itself when connecting to PC via Mass...
Hi guys,
My friend has a N97 and she changed the font using E:\Resource\Fonts\ folder method. The font was successfully changed; however, she didn't like it.
So she decided to change back the font, but whenever she connects the N97 to PC via "Mass Storage" mode, the phone restarts itself, and by that I mean EVERY SINGLE TIME it'll restart.
Therefore we tried "PC Suite" mode, but we're unable to make any changes to the Fonts folder (ie delete / rename / cut-paste).
I've also tried using X-plore, but whenever I try to delete the [s60snr.ttf/etc...] files, xplore will give me an error: "Can't Delete File: E:\Resource\Fonts". I'm sure that the file isn't in "read-only" if that helps anyone.
The fonts are stored in the 30gb internal memory inside the N97, so it's impossible to swap out the memory and delete on another phone/computer.
I appreciate any answersHi Guys,
I had same problem with my N97 mini. I do not have external memory card. I installed 'FONTS' in my mass memory. Font changed but if I connect my phone in mass storage mode, phone resets.
Here is what I did,
1. Copy all my data in PC using PC suit mode ( I suspect back utility will not work here because it will restore the back up including fonts folder in mass memory. I am not sure though). Also copy RESOURCE folder in your PC ( you can delete fonts folder in this copied folder in PC. I made a mistake of copying only RESOURCE folder you can copy all the folders from mass memory and restore it later.
2. disconnect the phone from PC
3. Open , Office --> File mgr. --> Mass Memory --> got to options --> Scroll down --> format mass memory.
That's it.
Your phone will be 'shut down' after formatting is completed.
Restart the phone connect it to PC suit. You might not be able to see mass memory. In that case connect it in ' mass memory' mode. You can find your phone is not resetting. Copy RESOURCE folder from PC with out fonts folder.
You may reinstall firmware and reinstall all the application you need.
It worked form me. Hope it works for you. Do it on your own risk. Do not forget to copy the data from mass memory.
You may find HARD RESET options (*#7370#) but it only resets your C drive and not F OR G Drive.
If you have installed Fonts in G (External memory). I guess you can just remove it from phone and remove the fonts folder easily. Just remove external memory use card reader to connect it to PC and remove.
CHEERS
