Creating a new instance ofthe database

I'm working on Linux and communicate with the Oracle 8 database from my java program. My problem is ... I want to create a new instance of the database so that my diff. programs will communicate with diff. users.,
Please crack it out.

I suspect you'll get more help if you address this question to the Linux forum. This question appears to have nothing whatsoever to do with the Oracle ODBC driver.

How can i create a new instance on unix

Hi,
How can i create a new instance(instance only) on UNIX and how can i mount my database with this new instance.

If you simply create a pfile and startup nomount with it, then -in theory- you have an instance running ( this method is used e.g. for restoring a rman backup )
2) You can't. Database files are bound to a certain instance. What you can do is recreate an instance with e.g. a different name, using the scripts generated by a 'alter database backup controlfile to trace;' command

PS2013 - When creating a new instance of Project Server hangs in 'Waiting for resources' status

Hi,
I have one instance of Project Server 2013 fully operational and I tried to duplicate the instance to make some tests. As I know the issue of using the same Content Database of Project Server in the same Server Farm, I used the powershell backup/restore/dismount
and mount the content database to change the site IDs to avoid index duplication. The Project server database was a regular SQL backup and restore in another database.
I created a new Web App in the port 90 as show below.
Then I included the Content database of Project Server as separated DB from SharePoint for this new SharePoint -acme90 and I tried to create the new instance. The creation hanged in "Waiting for Resources" status.
To make another check excluding the reuse of the SharePoint-80 I tried to create another instance both in the SharePoint-80 where is the working instance and in the SharePoint-90, everything default and again they all hanged in Waiting for Resource.
If I try to create the instance using PowerShell I got the following error:
PS C:\Users\epm_setup> Mount-SPProjectWebInstance -DatabaseName Test_EPM -SiteCo
llection http://acme02/epm -Lcid 1046
Mount-SPProjectWebInstance : Cannot find an SPSite object with Id or Url:

All SharePoint and Project Server services are running, all App Pools and sites are started at the IIS. I could not find a hanging timer job.
I cannot stop the hanged process or dismount the instances using Powershell since no instance created.
How should I solve the hanging status of creation of the instance? As they are in Hyper-V I can go back using one snapshot.
Thank you.

Hi Eric,
Thank your for your interest in this case.
I checked for running and crashed PWA jobs and deleted all of them just after restoring the snapshot and tried to create the new instance in the new web app in port 90 (besides the existing and working instance in port 80), but again it hanged in "waiting
for resources". There is not any timer job hanging, no error in event viewer or in log. So the error is well before working with cloned dbs.
Answering your questiion, I am working all on 2013. My intention is backup one instance of the port 80 and copy to the instance of port 90, changing of course the url and the index of the content db of SharePoint. The process I used was:
Create a new web app in port 90, creating a new SharePoint_Content_2 on a
http://server:90 site.
Created the top level site called Portal using the Team Site template.
Create a new content db for new instance of Project Server named EPM_Content_2 using Central Admin.
Backup content db from port 80 instance of Project Server and restore to this EPM_content_2 using PowerShell cmd.
Dismounted and mounted this Project Server content db to create new index for existing sites to avoid index conflicts.
Backup the Project Server DB from port 80 using SQL backup and restored as ProjectWebApp2 db for port 90 instance.
Tried to create a new instance of Project Server
http://server:90/pwa on web app of port 90 using the ProjectWebApp2 db and using the same app pool of the other instance. But as in the previous case, it hang out in "Waiting for resources".

First get a Telnet session on your platform.
In the following, foo is the name of the database to be created. Obviously you will replace this in your script names and script contents with the name of the database you are about to create.
The values of parameters, filenames, distribution of files across filesystems, numbers and sizes of rollback segments and redo logs contained in these scripts should not be considered to be "recommended" in any way. These are just examples to demonstrate syntax. (Although the values given here will create a perfectly viable database.)

Whlie creating a new instance, listener doesn't work

Hi
I got some problem while install a new instance.
Maybe listener configured incorrectly
please help me out.
I created a new instance(SID:BUS) by myself.
I didn't use DBCA or anyother tools
There's legacy instance on my NT server.
That's why I have to add a new instance.
Here's list of command I've issued
1. set initBUS.ora
2. register as a service
3. startup with nomount
4. issue create database command
5. run those script
@C:\oracle\ora92\rdbms\admin\catalog.sql
@C:\oracle\ora92\rdbms\admin\catproc.sql
@C:\oracle\ora92\sqlplus\admin\pupbld.sql
6. restart
The problem is I can't connect to new SID(BUS) even though I add new sid to listener.ora(legacy sid works fine)
I am sure that my new instance's listener works fine with this command
c:\>lsnrctl status
but it has unknown status ( I don't understand what stands for)
when I try connecto sid(BUS), system back this msg
SQL> conn sys/oracle as sysdba
ERROR:

what is the problem?
or which file or configure do I have to check?

Venki,
The ORA-00942 is okay because there is no existing object. But what stuck me is the ORA-01921 error which may indicate that this might not be a new database.

Are there any existing databases on this server? Have you tried to create it on other machine?I searched on Metalink too and found Doc ID: 237486.1 ORA-29807 Signalled While Creating Database using DBCA which say that eroror could be ignored. You may want to review that as well.

Unable to create a new instance in Hyperion Conf Utility

Hi,
I have installed Planning 9.3.1 on XP Prof. Everything is configured correctly except for the instance. I try to create a new instance and system gives out the following -
"System failure : Error while retrieving xml from database"
I have re-installed and configured Planning thrice to check that error isn't on the installation side.
Guru's, please provide your insights on this. If the instance is created, I can start working on the applications..
Thanks for your time,
Varma.

John and YM,
Thanks for your response.
I have two laptops - XP Prof and Windows 2003 Server. I am encountering the same problem on both. I have configured everything correctly with Shared Services. Only options that show pending are - Product Instance Registration and Deregister from Shared Services.
I have even started the services in the Same Order mentioned but to no use.
When I start planning, I see a message come up -
Can not get JDBC connection.

Schedule Webi (and Crystal) report without creating a new instance

Hi all,
I'm looking for the way to not create a new instance of the report when we schedule a report? Is it any actions on the InfoObject object? Or is it just impossible to do?
Thanks in advance !
Edited by: jerome.vervier on Nov 21, 2011 11:40 AM

Hi,
With regards to your query, whenever a report is scheduled an instance of it will be created.
Therefore, it is not possible to schedule a report without creating an instance.

How can i create a new and tableless database using database configuration

How can i create a new and tableless database using database configuration

How can i create a new and tableless database using database configuration
Just don't install the sample schemas. See the installation guide
http://docs.oracle.com/cd/E11882_01/server.112/e10831/installation.htm
Using the Database Configuration Assistant
When you install Oracle Database with the Oracle Universal Installer, the sample schemas are installed by default if you select the Basic Installation option. Selecting the sample schemas option installs all five schemas (HR, OE, PM, IX, and SH) in the database. If you choose not to install the sample schemas at that time, you can add them later by following the instructions in section "Manually Installing Sample Schemas".
Choose a custom install and don't install the sample schemas.
All other schems/tables installed are REQUIRED by Oracle

Problems when creating a new instance of an Input parameter for a REM

I am working in a small demo which calls a Remote Enable Function Module in order to read data from the back end system. Since the function module I need to call ("BP_BUPA_SEARCH_BY_USER") is not Remote Enable I created a copy of it and made it Remote Enable ("Z_BUPA_SEARCH_BY_USER"). I have created the model within webdynpro without any problems but when my application reaches the line where I create a new instance of the object Z_Bupa_Search_By_User_Input (see below the source code), just before to call the remote function, the application stops there. I have exactly the same code in another bapi calls and it works fine. I am wondering if my problem has anything to do with the fact the function module i am calling is the function module I created. Any advice is very welcome.
Regards,
Diego.

Service Manager 9.21: How to create a new instance of scautolistener and assign a port to it.

Hi,
2 instances of scautolistener are already running and i want to create a new instance of scautolistener.
The sm.cfg file entry of scautolistener instances are:
sm -scautolistener:12670 -debugscauto -log:..\logs\scauto.log
sm -scautolistener:12690 -log:..\logs\scsmtp.log
Please guide me as how to create a new instance of scautolistener.

first, you cannot create instances of methods. but you can create instances of classes (==objects).
the algorithm for primes does not work yet (its your work) but i inserted the code to create your object.
import java.math.*;
public class IsPrime {
public boolean isPrime1(int arg){
for(int e = 2; e < arg; e++){
int remainder=arg%e;
if(remainder==0){
System.out.println("This number is not a prime number");
break;
else {
System.out.println("This number is a prime number");
break;
return true;
public static void main(String[] args){
System.out.println(args.length);
if (args.length>1){
System.out.println("Sorry you can only enter one number");
else{
String sNum =args[0];
int iNum=Integer.parseInt(sNum);
IsPrime myPrimesObject = new IsPrime(); // here is your object
if (myPrimesObject.IsPrime1(iNum)==true)
System.out.println("is a prime");else System.out.println("is not a prime");
}

Create a new instance of a class without starting new windows.

I've a class with basic SWING functions that displays an interface. Within this class is a method which updates the status bar on the interface. I want to be able to reference this method from other classes in order to update the status bar. However, in order to do this, I seem to have to create a new instance of the class which contains the SWING code, and therefore it creates a new window.
Can somebody give me an example, showing how I might update a component on the interface without a new window being created.
Many thanks in advance for any help offererd.

Many thanks in advance for any help offererd.It sounds like you have a class that extends JFrame or such like and your code must be going
           Blah test = new Blah();
            test.showStatus("text");Whereas all you need is a reference to that Classs.
So in your class with basic SWING functions that displays an interface.
You Might have something like this
          // The Label for displaying Status messages on
          JLabel statusLabel = new JLabel();
          this.add( statusLabel , BorderLayout.SOUTH );What you want to do is provide other Classes a 'method' for changing your Status Label, so in that class you might do something like:
      Allow Setting of Text in A JLabel From various Threads.
     And of course other classes......
     The JLabel statusLabel is a member of this class.
     ie defined in this class.
    @param inText    the new Text to display
   public void setStatusText( String inText )
                final String x = inText;
                SwingUtilities.invokeLater( new Runnable()
                          public void run()
                                   statusLabel.setText( x );
}You still need a reference to your first class in your second class though.
So you might have something like this:
        private firstClass firstClassReference;        // Store Reference
        public secondClass( firstClass oneWindow )
                      // create whatever.........
                     this.firstClassReference = oneWindow;

Creating a new instance of a class within a superclass

I have a class with 2 subclasses and in the top classs I have a method that needs to create a new instance of whihc ever class called it.
Example:
class Parent
void method()
addToQueue( new whatever type of event is calling this function )
class Child1 extends Parent
class Child2 extends Parent
}What I mean is , if Child1 calls the method then a new Child1 gets added to the queue but if Child 2 calls method a new Child 2 gets added to the queue. Is this possible?
Thanks.

try
void method()
addToQueue(this.getClass().newInstance());
}Is this what you want ?Won't that always add an object of type Parent?
no if we invoke this method on the child object...
we currently dun know how op going to implement the addToQueue()
so... just making my guess this method will always add to same queue shared among
Parent and it's childs......

How to create a new instance of a method

How can I create a new instance of
public int IsPrime1(int arg) method in my main program and execute it. It has to be a non static method.
I have this code
import java.math.*;
public class IsPrime {
     public int IsPrime1(int arg){
               for(int e = 2; e < arg; e++){
                    int remainder=arg%e;
                         if(remainder==0){
                              System.out.println("This number is not a prime number");
                              break;
                         else {
                              System.out.println("This number is a prime number");
                              break;
     public static void main(String[] args){
          System.out.println(args.length);
          if (args.length>1){
                    System.out.println("Sorry you can only enter one number");
          else{
          String sNum =args[0];
               int iNum=Integer.parseInt(sNum);
}

first, you cannot create instances of methods. but you can create instances of classes (==objects).
the algorithm for primes does not work yet (its your work) but i inserted the code to create your object.
import java.math.*;
public class IsPrime {
public boolean isPrime1(int arg){
for(int e = 2; e < arg; e++){
int remainder=arg%e;
if(remainder==0){
System.out.println("This number is not a prime number");
break;
else {
System.out.println("This number is a prime number");
break;
return true;
public static void main(String[] args){
System.out.println(args.length);
if (args.length>1){
System.out.println("Sorry you can only enter one number");
else{
String sNum =args[0];
int iNum=Integer.parseInt(sNum);
IsPrime myPrimesObject = new IsPrime(); // here is your object
if (myPrimesObject.IsPrime1(iNum)==true)
System.out.println("is a prime");else System.out.println("is not a prime");
}
