Create multiple instance in a database

is it possible to create multiple instance in a database.if possible then is it possible to activate many instance at a time.(in personal edition)

Instance in Oracle refers to the Oracle database "engine" - a collection of processes using a shared memory area, accessing a physical Oracle database.
Multiple instances are possible on the same platform for different physical databases. But not a Good Idea..
Multiple instances on different platforms are for the same physical database using Oracle Real Application Clusters, aka Oracle RAC.
Thus your question does not make a lot of sense. My guess is that you are in fact refering to an Oracle session instead as this is "in the database" as you refered to.
Each client that connect to Oracle, creates/establishes an Oracle session. A single client uses one (usually the default) or more sessions (usually used by a multi-threading client).
By default, the Oracle Instance supports multiple Oracle (client) sessions. Including Personal Oracle. In the past, Personal Oracle limited (via the Listener) the number of remote clients (i.e. clients on other platforms) that can connect. I would assume that this is still the case. I however do not recall that there were a limit imposed on the number of local sessions that could be created - the limiting factor here is afterall the power and resources available by the PC. It's very unlikely that a common PC will be able to support a Personal Edition Oracle instance and 100's of local client sessions at the same time.
If you do mean instance as per the strict Oracle definition - why would you want to create two Oracle instances (each with its own physical database) on a PC? That does not make sense on a large db server platform. It makes even less sense on a small PC platform.
Each Oracle instance has overheads (processing and memory). Each physical Oracle database has overheads (system space, temp space, redo, logs, etc). Why duplicate these overheads?
On a single platform - what can two Oracle instances (less capable because of reduced resources availability) do what a single Oracle instance cannot do faster and better and more effectively? Thus is it not a Good Idea to run multiple instances on a single platform. (exceptions acknowledged)

Hi ,
I would like to know how to create multiple instance on same database . I know that some people use database configuration assistant to do this but i could not figure out how they did it.
Any how if some one can help me with this and can give me links of this it would be great help for me.
Thank you for reading my problem and helping me !

Creating multiple instances for a single file in B2B

Hi,
I have a requirement to read the camt.053 file from the remote partner using Oracle B2B and send the file to oracle AIA and insert the data in the ERP database tables. I am able to read the file successfully through B2B using listening channel and send the data to AIA and insert the data in ERP tables but, if there is any error occured while inserting the data in the ERP tables it is creating multiple instances(6 message count) for the same file in B2B reports. where as it is creating only one entry in reports in case of successful insertion. I have not given any retry count in listening channel nor in the database adapter in SOA/AIA composite. I am confused from where B2B is retrying the message ? Do i need to set any system properties? Could you please guide me to resolve this issue?
Regards,
Nishanth.

App message delivery is not retried in B2B, rather failed messages are delivered to the IP_IN_QUEUE. Please enable the logging for B2B engine in TRACE 32 mode and run a test to reproduce the behaviour. Post the log here or mail across to my id (in my profile).

Can I create multiple instances of realplayer plug-in in one jsp page?

I want to play meny video files in one jsp web page, these video files are to be played with the embeded plug-in of realplayer, each plug-in was linked(use its SRC property) a different video file. But, to my surprise, when I press the play button, every player played the same video file,not its specified file.
I have no idea why it did so and what can I do?
Whether can I create multiple instances of realplayer plug-in in one jsp page, that is to say, each instance is independent of others?
thanks in advance!

Generally speaking, Internet Explorer tries not to launch multiple versions of a plug-in. So what's happening is that you load the first video clip, and then before it has a chance to play, you load the second video clip into the same window. (It's like changing songs in WMA.)
In some cases - this may not work for Real Player, but it's worth trying - if you spawn a new window through a hypertext link and then launch the plug-in in that window, IE will treat it separately. Otherwise, you could not, for example, run two Macromedia Flash applications from different web sites at the same time.
Keep in mind that only one program can access the soundcard at a time, so Real Player may purposely "pause" or "cancel" other video streams until the active one finishes. If you were using the desktop version, selecting another video by any means aborts the currently running video (i.e., RP won't let you create a separate instance of it).
The easiest solution is to create a wrapper JSP file that takes the name of the video clip, and plays it. Call that JSP and specify that it should be opened in a new window via the TARGET keyword in the anchor tag. Then hopefully RP itself won't block a second window from running.

Creating multiple instances of a class in LabVIEW object-oriented programming

How do you create multiple instances of a class in a loop? Or am I thinking about this all wrong?
For instance, I read in a file containing this information:
Person Name #1
Person Age #1
Hobby #1
Hobby #2
Hobby #3
Person Name #2
Person Age #2
Hobby #1
Hobby #2
Hobby #3
Person Name #3
Person Age #3
Hobby #1
Hobby #2
Hobby #3
If I define a Person class with name, age, and an array of strings (for the hobbies), how can I create several new Person instances in a loop while reading through the text file?
FYI, new to LabVIEW OOP but familiar with Java OOP. Thank you!

First of all, let's get your terminology correct. You are not creating multiple instances of a class. You are creating Objects of the class.
Use autoindexing to create an array of your class type.

How can I force TestStand to create multiple instance of an activex server instead of share the same reference?

Hi, All:
     I am trying to migrate a application coded by VC++ to TestStand+CVI. This application opens multiple serial com ports and send commands to test targets, and get responses from these targets. The VC++ application creates multiple thread, and every thread create an activeX server instance which is responsible for opening serial port,sending test commands ,and getting response. It works fine as every thread has itsown activeX instance, so data and commands can be handled in the right serial port successfully.
     Yet when I works on TestStand, I got problems. I choose parallel model as the process model. I create a activeX object reference with AxtiveX/COM Adapter, and store the reference in a sequence local varialbe. If there is only 1 testsocket, It is OK. But if there are multiple test sockets, and communication between the application and test targets will be directly to the last test target. I try to popup a message within a execution to indicate the value of the activeX object reference, and all of them are identical. But this is not the behavior I want.
    So, is it possible to force TestStand to create independent instances of an activeX server? How can I make it work?
Thanks

Thanks for your comment, Dan.
      Yet I do get problems as none of us know how to program an activeX server so that it can be forced to be a single-instance or multiple-instance.
As I mentioned earlier, there is existing application which is written by VC++ can create multiple instances of this activeX server, all I have to do is to create multiple threads, and initiate an instance of this server to contrl multiple test targets.
     My colleague said he creates the server with VC++ ATL, and cofigure it to be dual-interface and STA. And in the VC++ application side(client side), I use smart-pointer in threads to create an instance of the server:
IMySerialServer pIMySerialServer;
  HRESULT hr = pIMySerialServer.CreateInstance("UUTCmd.MySerialServer");
  if(FAILED(hr))
   AfxMessageBox("Fail to create instance.");
And then I got multple instances of the activeX server. Every thread can have itsown com port, can send/receive commands indepently. I have no idea how can I make it work on TestStand. Would you show me some reference documents or sample codes?
Thank you

How to create multiple instance of Jboss with different port number

Hi all
Please tell me steps to create multiple instance of Jboss with diffrent port number.
I tried with this steps, but it does not work for me.
In conf/jboss-service you will find the binding manager.
   <mbean code="org.jboss.services.binding.ServiceBindingManager"
     name="jboss.system:service=ServiceBindingManager">

     </attribute>
   </mbean>Please help me on this.
Thanks in advance

It is the name of the website for JBoss. That seems rather obvious to me, and you would have found out for yourself if you had tried it.
Your question is not a Java question and doesn't belong in these forums. It is a JBoss question and you should ask there, or more probably have a look at the JBoss documentation first.

Creating multiple instances of JTextField

Hy, I have a JtextField and a JButton. Depending on the
value inserted in the JtextField, when I click on the JButton,
I want a new window to open and create multiple instances of
JTextField.
I tried to use a for loop, but how do I differentiate among
the different JTextField
thanks

Just put the JTextField instances in an array.see below:
int NumOfJTextFiled=10;
JTextField jtextfieldArray[]=new JTextField[NumOfJTextFiled]
for(int i=0;i<NumOfJTextFiled;i++)
jtextfieldArray=new JTextField();

Then you haven't followed the method correctly. That error is
addressed specifcally on that site, as that error is the main
reason for the site. Did you read the note about the "known
bug" because of the one port that is not included in the
sample file?
If you had tried the first method (set up a second IP and
started both servers with the command line option providing
an IP) there is no way this error could happen.
If you followed the second method, and specified a different
port for every port listed (including the one that is not in the
sample file per default) then there is, once again, no way that
this error could happen.
The error happens on the second server because it is trying
to bind the same port, using the same address, as the first
server, which is impossible if you fully implement one of the
two methods described there.

Creating multiple instances

Below are two methods to create multiple instances. Clearly,
method 2 is more efficient. However, if I use method 2 I don't know
how to modify a specific instance later in my code. For example,
using method 1 I can just write:
tf1.alpha=0
but I don't know how I can target a specific instance using
method 2. Writing tf.alpha=0 will only target my last instance. How
do I put something in my loop to allow me to identify every
instance by name?

How to create multiple instances within same AS

Ramesh,
I have a unique problem. I might have to create B2B instances for 4 owners. As in BPEL, I can have separate domains for the 4 clients in the same instance; what is the equivalent in B2B?
I have a limited number of CPUs and need to install the instances on the same box and hence trying to be creative yet secure here.
Could you please provide some pointers.
Thanks
Shamik

Hello Shamik,
Please elaborate your use case. Is this just caters to user management or to really have different domain like bpel for four different users. Please see, b2b do not have the notion of BPEL domain, you might have to install multiple instances of B2B pointing to the same MR.
Rgds,Ramesh

Can we create multiple instances of a Bean in a JSP file?

Hi,
I am new to JSP & Servlets programming.
I need to write a servlet that connects to a database via JDBC ( using IBM DB2 dbms) , sets some Beans with the tuples in the relevant table.
Then, I need to have a JSP "read" ( or "get") info from the Beans & display the contents to the client.
( At a time only 5 tuples must be visible in the UI , with Next & Prev links ...)
I am using Tomcat 4.0 for this...
Can any one please help me regarding HOW to go abt it ?
Esp., should we create 1 instance of a Bean , ( say "DataBean") for EACH tuple , or is there a way to do it with only 1 instance...
Please, guide me... ( if not possible, at least give me some hints to some GOOD resources ( books, sites,etc.), that deal with this kind of applications)
Thanks,
Raghu.

Once again, thanx a lot for your detailed help -- evnafets !!
I think I am gaining in my knowledge of JSP & Servlets thanks to your help...
Now, I am tackling the issue of selecting the BEST way of "STORING" which "PAGE" no. I am displaying.
Say, I have only 15 tuples(ROWS), & with 5 tuples displayed per page, I have to have 3 "pages", & I need to accomplish the handling of "Prev" & "Next" links using only 1 Servlet & 1 JSP ( apart from the Authorization servlet ).
I am thinking of storing a "session-scoped" variable called "page-num". Do you think it's the best way?
Or should I score it as an "application-scoped variable" ( i.e., in the ServletContext ...) ??
Also, I have got no clues as to which of the following would be a better idea :
(a) Fetch ALL the tuples in the table & set as many beans. And then display the corresponding 5 tuples in each page.
Here, more bean instances are needed to hold the data which gets repeatedly passed around ( when Prev & Next links are clicked ).
OR ..
(b)Fetch only 5 tuples at a time . I think this may be done by creating a scrollable Resultset & then moving around to the appropriate ROW by saying
resultSet.absolute( (page_num - 1)*5 + 1 ); & then fetching 5 tuples relative to this row.
In this case I will need atmost 5 Bean objects per request.
And YES, one more thing , WOULD you PLEASE try & give me some guidance towards some good references to JSP, Servlets & J2EE ? ( Links, Books, anything ! )
Sorry for the TROUBLE I gave, but THANKS a lot for the TROUBLE u took ! ;-)
Thanks & Regards,
Raghu

In Oracle 9 Application Server can we create multiple instances???

Hi I need one help this is regarding to the oracle 9 application server in this can we create the multiple instances??
my application was already developed and currently it is working with one instance for this i need to create the another one more instance which is same as existing and my application is web application developed in Forms6i and the db is oracle 9i my requirement is to create one more instance what are all the configuration files need to be modified and please give this info ASAP....

It is still not very clear. What do you mean by creating "one more instance of the same application in the same application server"? By "application" do you mean another instance of OC4J in same Application Server Instance? If yes, you can do that. I mean you can create another OC4J component in same Application Server Instance without doing another installation. Refer this for details:
http://download.oracle.com/docs/cd/A97329_03/core.902/a92171/config.htm#1010793
If you are looking to create another Application Server Instance out of same installation/binaries (i.e. Oracle Home) than the answer is no. You can not create multiple Application Server Instances out of one Oracle Home. You will have to do another installation in a different Oracle Home and that's how you will get another Application Server Instance.
Hope this helps.
Thanks

How to create an instance of the database

No that won't work. I have to set it up independant from each other because I can't get to Uni until Monday and I want to have this done over the weekend really.
The main issue seems to be now how to create an instance of the database

To create a database:
you first connect as internal (user) with the passeword 'oracle'
the syntax is: connect internal/oracle
You type in this script:
STARTUP NOMOUNT PFILE=$PFILE
CREATE DATABASE db01
LOGFILE
GROUP 1 ('c/oracle/oradata/db01/redo_01a.log',
'c/oracle/oradata/db01/redo_01b.log'
) size 100k,
GROUP 2 ('c/oracle/oradata/db01/redo_02a.log',
'c/oracle/oradata/db01/redo_02b.log'
) size 100k
MAXLOGFILES 32
MAXLOGMEMBERS 2
MAXLOGHISTORY 1
DATAFILE 'c/oracle/oradata/db01/system01.dbf'
size 7M
MAXDATAFILES 254
MAXINSTANCES 1;
This script could be modified to reflect the features you want for your database.
db01 = the name you can give to your database
Good luck,

B2B Creating multiple instances in error scenario

Hello All,
We do have B2B configured in clustered environment, its working fine in successful transaction but creating two instances in case of any error in B2B or SOA process.
When I debugged, I found that in error scenario both servers(configured in cluster) are trying to process the record and hence failing the both.
Could any one please advise on the possible reasons/solution for the problem.
Any suggestion would be appreciated.

Do you have B2B EM property "b2b.HAInstance" set in your domain?
b2b.HAInstance - Set this property to true to ensure only one node in an High Availability (HA) cluster starts a polling thread for the configured File, FTP, or Email channels. Without this property being set, each node starts its own polling thread and could pick the same file multiple times.
The default value of this property is false.
A restart of all the nodes in the cluster is required to ensure each node works in the expected HA Mode.
