How to synchronize two database

Hi All,
I am using oracle 10R2 in solaris 10. I am trying one scenario, but unable to come with solution. please give your suggestion.
In machine A, I have one database called DB1 and its up and running. Now I took cold backup and created the same database in another machine called
machine B.
Now the database are running in both machine A & B ( both are same at present).
Now I am going to do some changes in machine A ( create tables, add rows, delete roes, add user, etc etc etc ), Now I want to apply those changes to
machine B on daily basis.
I dont want to do logical standby database, because i am going to use the machine B also ( i will open always).
Any other way to do this ???? like export or apply logs ??
I am not sure about this
Kindly give your suggestion.
Regards
Kumar

Use Oracle Streams for updating Both Sids
Oracle Streams, a built-in feature of the Oracle database, is a data replication and integration feature. It provides a flexible infrastructure that meets a wide variety of information sharing needs. Oracle Streams enables the propagation of data, transactions and events in a data stream either within a database, or from one database to another.

How to synchronize two database in ur java program

Hi All
How to synchronize two data base of mysql using java programing language?
If somebody has any idea that will help me a lot.
Thanks and regards
Srikant

Of corse I have an idea, but not good!
If you know the database stucture then copy data from one to another.
Open 2 connections: one to source and one to dest.
And:
String sql = "SELCET * from mytable1";// from source
string sql2;
Statement st1 = connSrc.createStatement();
Statement st2 = connDest.createStatement();
ResultSet rs = st1.executeQuerry(sql);
while(rs.next()){
sql2 = "INSERT INTO mytable1 ('field1', 'filed2') VALUES ("+
"'"+rs.get(filed1")+"',"+
"'"+rs.get(filed2')+"'"+
st2.executeUpdate(sql2);
// the destination was cleared before this: DELETE FROM mytable1 WHERE 1
This is a mysql sample without processing the errors.

How to synchronize two fpga DIO?

Hi!
I am using two FPGA 7962R (flexrio) with each 6581 terminal board in PXIe-1082 chassis. My problem is how to synchronize two 7962R digital output with PXIe-1082 chassis backplane signal Dstar* or Clk10 or DAQ signal.
Actually I tried the synchronization with one DAQ counter clock (confering 'Gen Dig Pulse Train-Finite_NI. vi') , and get the signal PXI-Trig0 by source terminal and target terminal connection, but that one does not work properly. Especially, one trigger signal in HOST to set the starting point of each FPGA (7962R), make error by depending on the trigger signal value(Hz value and Timed loop clock in FPGA vi). It was very tricky and not reliable. (I am attaching figure files as explaining the situation)
My aim is simply to use two FPGA 7962R Digital output as one FPGA, for controling X-axis, Y-axis with each FPGA, while able to change each FPGA (X-axis, Y axis) digital output value. Because the synchronization is not correct, X,Y axis control with Two FPGA currently is out of target if I use simply while-loop design in HOST and timed-loop design in FPGA vi. What is correct design to synchronize the two FPGA 7962R without using PFI line, only with PXIe-1082 chassis backplane signal and able to change the digital output value? Please let me know any idea for HOST vi, FPGA vi programming.
Many Thanks

Hi can anyone explain me how to syncronize two database using jsp?

Hi can anyone explain me how to syncronize two database using jsp?

I thinking than you really need the jsp page for calling the java methods whith sincronize the database.You think wrong.
You wrote a bad question.What was bad about it?
You need a java method for sincronize the two databases using a jsp page.No you don't, see my answer.

How to Synchronize two methods or more methods

HI All,
As a java starter in learning Synchronization. how simply can I Synchronize two methods
for example I have the following.
public class Process {
public static void main(String args[]){
process1();
process2();
private void process1(){
private void process2(){
}

You're being really ambiguous. You could "synchronize" those methods by adding the synchronized keyword to their method signature, in which case they will implicitly lock on the object they belong to. That's what most people will think you mean when you say synchronized. Is that what you meant? Or did you mean what BDLH was thinking in that you wanted to lock something, then do 1,2,3,4, then unlock it? That's something different. Be specific!

Using RMI to synchronize two databases

Hello
I have studied Java for some time, but never had
the opportunity to work in a "real project", but
now I have something to do...
I have the following situation: two offices
of a company, the central one running SQL Server
database and other running Oracle, must change
information, reading data from Oracle and saving in
SQLServer and vice-versa. The programs should be
running all day, checking at specified periods of
time if there is some information to be updated
in any database.
The offices are phisically far, so it should be
used Internet to make the connection (both sites
are connected to Internet 24h).
I was wondering on using the Java RMI technology
to achieve this. I have read the official Sun
documentation about RMI and some articles, and I
found it very interesting, and pretty easy to
implement.
But I have some "real world" questions:
- Is RMI the ideal solution for this problem, or
there is some newer or more adequate one?
- At first it would be a small amount of data
to be synchronized, but if it grows a lot or
more offices are to be connected, is RMI performance
good? (is it quick?)
- About security - is RMI secure? I mean, I think
the server program should be listening a port in a
IP address open to ALL the internet... How safe is
the user authentication, or this is responsability of
the application?
- What is the relationship between RMI and proxies,
firewalls etc? Are they compatible?
- XML is something to think about using for this
application, or it have nothing to do to the job?
The initial option was using a Microsoft solution
to make this application :(, but I would be very happy
if I could use Java ;) , but I have to have the
adequate technical base to suggest it...
So, any help would be very welcome!

Here's a set of (some) answers based on my experience (which is NOT synchronizing two databases, but on synchronizing sets of files across a tree of file servers.)
Hello
1. It sounds like two databases must be cross-synchronized. You didn't say what the platforms were, but if they are mixed, then java is a positive choice.
2. Java rmi is fine for doing this kind of work. However I can't give you any performance guarantees. You probably need to get some fine requirements and write some model programs.
3. YOU are responsible for security. RMI gives you connectability; you have to develop some kind of cross-authentication procedure as part of you application.
4. To work over the internet, you will have to develop some way through firewalls.
o If the two sites use "Virtual private networks", then both the security issue and the firewall issue are mostly solved for you.
o Otherwise, and maybe even with vpn, you will have to do a little bit of work to use fixed port numbers. (The way rmi works is that there is a listener at a fixed port which will let a remote program "look up" a local object; after that, communication takes place object-object over a randomly-assigned port.) It takes about a dozen lines of code to make this work.
5. I don't think XML has anything to do with this problem. It MAY help you if you have serious data conversion issues. I hear it's a pig.
Finally, an application item that may or may not be an issue: Two databases, two platforms == possible character set conversion problems.

How to compare two database on different servers

hi,
I want to compare two database on different servers in oracle.first i want to ckechk thier structures and then data.i m using oracle 10.2.0.plz help me out
Thanks in advance

In terms of structures, there are various tools out there that can do this, such as TOAD which can do a database compare.
In terms of data comparisons, that will depend on what sort of results you are expecting to see. I'm sure some tools will do it for you, but it can be just as easy to write your own comparison using a database link from one database to the other.

How to synchronize two NI9215 DAQmx cards?

Hi there,
I'm using two NI9215 DAQmx cards (4ch simultaneous sampling analog inputs) in a chassis type cDAQ-9174.
Since I need to aquire 8 channels simultaneously I've two NI9215 cards.
My question is how do I configure these cards to be synchonized?
I'm using LabVIEW2009 SP1 Dev. Suite
Thanks for answers!
Solved!
Go to Solution.

One of the beautiful things about CompactDAQ is that you can put multiple modules of the same time (Analog, Digital, etc.) into the same task and they are automatically synchronized. So, to synchronize the two modules, create one Analog Input task and reference the channels as "cDAQ1Mod1/ai0:3, cDAQ1Mod2/ai0:3". This will automatically synchronize the two modules together.

How to synchronize two USB webcams (each at 30fps) for a combined 60fps video? Three for 90fps?

Hello All,
Multiple-Camera Lab Application: How-To?
Exploring a loose-synchronization for cameras, low resolution, B&W=gray video capture, that may require up to 200fps, laboratory application.
Frames would be recorded serially, from 1_frame/10msec at 100fps to 1_frame/5msec at 200fps.
Consecutive frame-to-frame intervals do not need to be fixed at 10msec, they may vary a lot +/-50%, are non-critical.
Video recording may last up to 1_minute maximum real time (no sound recording needed at any time).
Specs say a generic USB2.0 webcam can record up to 30fps.
And USB2.0 is a half-duplex serial protocol.
Using two or more webcams in parallel, focused on the same scene, may yield a composite video capture at multiples of 30fps.And much lower price than a single dedicated high speed camera.
Ultimately all frames have to be assembled -in sequence- into one big video recording.
Any comments, any ideas? Did anyone try this?
Thank you,
Dan

Hi,
Sorry I am not much help about this. Creative webcams aren't built to work that way.

How to synchronize two scroll bars

Hi there,
Can anyone tell me how to go about to synchronize 2 JScrollPanes so that When the Scroll bar of the top Pane is moved, the scrollPane of the bottom pane also moves in sync. Thanks in advance.

1. get hold of the two scrollbars using getHorizontalScrollBar() or getVerticalScrollBar()
2. listen to their AdjustmentEvents using
addAdjustmentListener(AdjustmentListener l)
3. in the AdjustmentListener set the scrollPosition
of the other scrollbar, when an AdjustmentEvent gets
fired. You can use setValue(int)

How to synchronize two applications system

HI,
I work witj Designer 9i, in a Non-versioned Repository. I create a copy of an application system on the same repository.
I would like to know if there is some mechanism that will synchronize the two application system copies. What i want is how to automate the replication of any modification I made to the copy, in the original application.
Thanks for your help,
Malika

Hi Roel,
I want to do this because in our organization the repository is non versioned, and we want to make copies for the application system in purpose to sure that only Data modeler and DBA will access it. The developers can't update it. In the original application system we will replicate the changes and then developers go on with their Treatment modules.
Thanks for your reply ,
Malika

How to update two database tables when using DatabaseProvider

I'm a begginer and I've made an application which uses a database. In one page, I have a table which I've took it from "woodstock basic" palette. I was using DatabaseProvider to populate the table with data from a database table called "copii". My code is:
//i'm check all the rows in the table to see if the field "IDCOPIIC" =0 and if true I will put the value of "newCopiiId"
do {
if (copiiDataProvider.getValue("IDCOPIIC").equals
(new Long(0))) {
copiiDataProvider.setValue("IDCOPIIC", new Long(newCopiiId));
newCopiiId++;
} while (copiiDataProvider.cursorNext());
copiiDataProvider.commitChanges();
My problem comes now because I have another database table tided with a foreign key by this one and I want to update this one too when I'm updating the "copii" table. I don't know how to do it ...I've tried in many ways but is impossible. Can anyone help me ! I'm desperate...I cannot figure it out how I could insert, update in two tables in the same time when I'm using DataProvider .
Thanks in advance!

Hmm.
Not sure where your going with the <select> menu.
The description you made:
"Both have an id column, which is presumably the record's primary key, but you need to create a relationship by storing the primary key of one table as a foreign key in the child (related) table. For example, you should insert the primary key of the first table in the second table as user_id. That enables you to identify which username and password are related to an individual listed in the second table"
Seems to be the direction that I'm looking for.
Now my question is how do I insert the primary key of the first table in the second table as user_id?
>
>"For example, you should insert the primary key of the first table in the second table as user_id"
Since both tables have an id column and they both are the primary key, do I just change the name of the second tables id column to "user_id" then?
Or is there an actual "insert the primary key to another table" function that I don't know about?

How to link two databased

I have to link two tables from two differen databases.
select vendor from table a database e
select vendor from table b database c
how can i combine this two tables

You create a database link. Assuming you are on database e:
CREATE DATABASE LINK c_link
CONNECT TO name_of_c_database_user_with_select_privilege_to_table_b
IDENTIFIED BY password_of_c_database_user_with_select_privilege_to_table_b
USING 'c_database_tns_entry_name'
/Keep in mind 'c_database_tns_entry_name' must exists in tnsnames.ora on database e server.
Now you can:
select vendor from table_a
union all
select vendor from table_b@c_link
/SY.
