No, you don't want that. Your JSP should not know that there is such a thing as a database.

How to take a backup manually in oracle 11g express edition?

how to take a backup manually in oracle 11g express edition? i want to take backup of a database and want to restore later on on a different computer .

Stop database, and copy all files to another machine.That sounds to me to be the closest answer to the question posted. And perhaps the easiest solution.
Install XE on the "another machine", shut it down. Shutdown the source database. Copy the datafiles to the new host. Startup your "new" database, it will be an exact clone of the original.
To find out what files need to be copied, as system (or sysdba) run:
select name from v$datafile;
... file1, file2 ...
show parameter control
... control_files ... file1 ...
alter database backup controlfile to trace [reset logs];
show parameter diag;
... diagnostic_dest ... <drive:>|/diag_pathTo do a proper database clone its better to recreate the controlfile and reset the archive sequence number- leave out the controlfile copy part. In the diag_path location find the trace file under diag/rdbms/$ORACLE_SID/<db_name>/trace it should be the latest ora*.trc file.
The trace file has the commands to recreate the controlfile, which includes the datafiles and putting the tempfile back in place. If the datafiles are in a different location, i.e. in Windows going to a different drive, or you want do put datafiles in a different folder location, the create controlfile statement is the easiest time to get the file directories right.
If you add the "reset logs" qualifier (don't use the brackets!) you'll get just the reset logs version of the create controlfile statement, otherwise you'll get both NORESETLOGS and RESETLOGS versions of a create controlfile statement, run one or the other. Not both. Not the entire trace file, just the create controlfile, alter database open [reset logs], alter tablespace temp add tempfile ... bits. No recovery is needed for a database that is shutdown when datafiles get copied to a new location/host.

Hi,
Since you are working with Oracle10gm you may check DBMS_DATAPUMP:
http://download.oracle.com/docs/cd/B19306_01/appdev.102/b14258/d_datpmp.htm
Or like any shell command, you can use java programs.

How to execute dir dos command in Runtime Execution

Hi All,
Does anybody know how to execute the dir command in DOS in the runtime execution
for example,
when we open the command prompt,
c:\Documents and Settings\java> e:
e:\cd java
e:\dir *.*
how we can list the directory in runtime execution?

Process childProcess = Runtime.getRuntime().exec("cmd /C dir *.*");or try with
ProcessBuilder pb = new ProcessBuilder("cmd /C dir *.*");
Process childProcess = pb.start();
NOTE: We can use the ProcessBuilder class from J2SE 5.0+.
for further reference check the below link
http://www.javaworld.com/javaworld/jw-12-2000/jw-1229-traps.html?page=3
and don't forget to go through API documentation for java.lang package
http://java.sun.com/j2se/1.5.0/docs/api/java/lang/package-summary.html
and if you want to implement it through Java which provides you a list of Files & directories in the present directory here is an example of such code snippet REF:as insisted by my fellow poster.
File file = new File("<present_directory_path>");
if(file.isDirectory()){
   String fileNames[] = file.list();
        for(String fileName:fileNames)
           System.out.println(fileName);
fileNames = null;
        or for detailed info use
         File files[] = file.listFiles();
         for(File fileEntity:files)
            System.out.println("FILENAME:"+fileEntity.getName+",IS FOLDER:"+fileEntity.isFolder()+",ABSOLUTE PATH:"+fileEntity.toString()+"FILE SIZE:"+fileEntity.length());
         files = null;
}and please do not forget to go through File API Documentation provided as recommended by my fellow poster.
hope this might help :)

How to call Operating System commands / external programs from within APEX

Hi,
Can someone please suggest how to call Operating Systems commands / external programs from within APEX?
E.g. say I need to run a SQL script on a particular database. SQL script, database name, userid & password everything is available in a table in Oracle. I want to build a utility in APEX where by when I click a button APEX should run the following
c:\oracle\bin\sqlplusw.exe userud/password@database @script_name.sql
Any pointers will be greatly appreciated.
Thanks & Regards,

Hi Guys,
I have reviewed the option of using scheduler and javascript and they do satisfy my requirements PARTIALLY. Any calls to operating system commands through these features will be made on the server where APEX is installed.
However, here what I am looking at is to call operating systems programs on client machine. For example in my APEX application I have constructed the following strings of commands that needs to be run to execute a change request.
sqlplusw.exe user/password@database @script1.sql
sqlplusw.exe user/password@database @script2.sql
sqlplusw.exe user/password@database @script3.sql
sqlplusw.exe user/password@database @script4.sql
What I want is to have a button/link on the APEX screen along with these lines so that when I click that link/button this entire line of command gets executed in the same way it would get executed if I copy and paste this command in the command window of windows.
Believe me, if I am able to achieve what I intend to do, it is going to save a lot of our DBAs time and effort.
Any help will be greatly appreciated.
Thanks & Regards,

How to restore the backup which we taken from db13 ?

Hi .........
I am taking full back up from DB13 to hard disk and tape drive every day.
Please tell me how to restore this backup which is taken from db13.
4.7E, MSSQL , Windows 2003 server.
Gayatry.

If its the same server you took the backup from the backup history for the DB will be stored against it. If its a different server you will need to catalog the backup tape to read in the history/contents.
Lets assume its the same server, with the same file locations.
From SQL Ent Mgr - with SAP stopped.
right click the DB
select restoredb
select the set you want to restore from the history
select the options you need (ie leave off line for addition TL restore, or bring online)
It really is that simple - you cant go wrong (assuming you select the correct set!)

How to execute Linux OS command from ODI

We have installed Oracle data integrator on windows machine and want to execute linux OS command in a procedure or scenario from ODI .
How could i do that ?
I can see os command elements but they do not work, only windows commands work.There should be linux technology i think

Obviously you can execute Unix OS commands only on Unix OS. Why do you expect Windows to understand it?
The solution in your case would be executing your ODI scenarios with an Agent installed on Unix machine.

How to execute a Unix Command in java

Hi, Iam trying to execute a unix command on Sun Solaris by passing that command to a java program. How can I achieve this?
Thanks in advance.

Have a look at the javadoc around the Runtime.exec() method. If the command is a shell command then you might have to execute a shell as well as the command.
For example, if you wanted to run a unix command 'ls -l > output.txt' the you might have to pass the following string into the exec() method,
"/bin/sh ls -l > output.txt'

Is it possible to execute OS level commands through Oracle APEX?

Hi,
I would like to know if it is possible to execute OS level commands, say executing any command in command prompt using Oracle APEX.
Thanks!

Welcome to Oracle Forums!
Please acquaint yourself with the FAQ and forum etiquette if you haven't already done so.
Always state
<ul>
<li>Apex Version</li>
<li>DB Version and edition</li>
<li>Web server used.I.e. EPG, OHS, ApexListner Standalone or with J2EE container</li>
<li>When asking about forms always state tabular form if it is a tabular form</li>
<li>When asking about reports always state Classic / IR</li>
<li>Always post code snippets enclosed in a pair of {code} tags as explained in FAQ</li>
</ul>
I would like to know if it is possible to execute OS level commands, say executing any command in command prompt using Oracle APEX.If by OS you are referring to the client side, then NO.
Cheers,
