Executing SQL Loader ----- Using Java & C!!!!!!!!!!!!!

Hello,
We r confirmed that to execute SQL Loader,
One need to write an External Routine.
So First Step itself need to create a
'C' file which executes our sql Loader or
Using Java.
How Can I execute the SQL Loader (.exe)
using Java?
How can I proceed? Waiting ASAP. Thankyou

I have a nice piece of Java code that allows you to execute OS commands from within a PL/SQL block in Oracle. If you need the code send me an email. I know it works in Unix and it should work on most platforms.

Calling SQL Loader in Java

I am writing a Java application running on SUN Solaris to perform data feed from a number of csv files to ORACLE. I am to use SQL Loader to perform the loading. What I need is to kick off the SQL Loader in my code. My question is how to kick off the SQL Loader in Java.
One of option I am thinking is using RunTime.Exec(). Is the following code workable?
runtime.exec( "sqlldr CONTROL=foo.ctl, LOG=bar.log, USERID=scott/tiger" );
Althernatively should I write a Oracle store procedure to call the SQL Loader and Java call the store procedure?
Any thoughts and directions are welcome!
Regards,

Hi,
Can't you achieve the same thing using this
Class.forName("Driver");
Connection ocon=DriverManager.getConnection("url");
Once you have ocon then you can execute any query.
If this is not what you want,can you explain what SQLLoader means here?

Calling oracle SQL Loader from java program

Hi,
I want to insert data into oracle tables from a text files containing fixed length fields. I am using SQLLoader to achieve this. The requirement is to call the SQLLoader within the java program.
Does anyone know how to call SQL Loader from java program?
Thanks,
Varsha

Simply "exec" the sqlldr program with the parameters you need to pass to it.
Runtime.exec (........)
Try to pass all parameters needed including the username and password, and use the option "silent" to avoid output, and the option "log" to have a log file of the modifications that sqlldr has done to the database.

Calling SQL Loader using HOST command from Developer Forms 4.5

I want to execute a set of code from D2K Forms 4.5 which has interfface with Client - OS ( In my case Windows NT/XP). I want to execute SQL Loader from Forms using Host Command and then after completion of that process, I want to do next transcations ( depending upond success of HOST/SQL Loader).
How to achive this?
I tried writing code like this ...
l_vc_command := 'sqlldr73'
                    ||' USERID='||l_vc_username||'/'||l_vc_password||'@'||l_vc_connect_string
                    ||' CONTROL='||l_vc_filepath||'Upload.ctl'
                    ||' DATA='||LTRIM(RTRIM(l_vc_fileloc))
                    ||' LOG='||l_vc_filepath|| l_vc_log_file || '_' || l_dt_sysdate_str ||'.log'
                    ||' BAD='||l_vc_filepath|| l_vc_bad_file || '_' || l_dt_sysdate_str ||'.bad'
                    ||' DISCARD='||l_vc_filepath|| l_vc_discard_file || '_' || l_dt_sysdate_str ||'.dsc';
HOST(l_vc_command,NO_PROMPT);
After this command i want to do some other code execution. so even if it fails or success, next code is executed. How to control this?
Please help..

Forms6i running on W2000, Rdbms 8.1.7
in Forms I added a button TEST,
Trigger when-button-pressed : host('test.bat') ;
in directory .......\frm I added file test.bat :
REM ===============
cd /d C:\........\ldr
pause
sqlldr parfile=test.par
pause
type test.log
pause
exit
REM ================
now, pressing TEST button opens DOS window, telling me what's going on, running sqlldr, finally going back to forms
Are you using NO_PROMPT or NO_SCREEN option of HOST command ?
Had a look at Forms 4.5 manuals, there is no mentioning of (a)synchronously operation in connection with HOST command.

How do i connect to sql server using java?

hi ever body

Microsoft make a jdbc driver and it is readily available through MSDN. Here is a link http://msdn2.microsoft.com/en-us/data/aa937724.aspx. Whatever jdbc driver you are looking for, Google it, and if it exists you'll find it in 10 seconds.

Import and process larger data with SQL*Loader and Java resource

Hello,
I have a project to import data from a text file in a schedule. A lager data, with nearly 20,000 record/1 hours.
After that, we have to analysis the data, and export the results into a another database.
I research about SQL*Loader and Java resource to do these task. But I have no experiment about that.
I'm afraid of the huge data, Oracle could be slowdown or the session in Java Resource application could be timeout.
Please tell me some advice about the solution.
Thank you very much.

With '?' mark i mean " How i can link this COL1 with column in csv file ? "

How to execute SQL Script using windows powershell(using invoke-sqlcmd or any if)

OS : Windows server 2008
SQL Server : SQL Server 2012
Script: Test.sql (T-SQL) example : "select name from sys.databases"
Batch script: windows MyBatchscript.bat ( here connects to sql server using sqlcmd and output c:\Testput.txt)
(sqlcmd.exe -S DBserverName -U username -P p@ssword -i C:\test.sql -o "c:\Testoutput.txt) ---it working without any issues.....
This can execute if i double click MyBatchscript.bat file and can see the output in c:\testput.txt.
Powershell: Similarly, How can i do in powershell 2.0 or higher versions? can any one give full details with each step?
I found some of them online, but nowhere seen clear details or examples and it not executing through cmd line (or batch script).
example: invoke-sqlcmd -Servernameinstance Servername -inputfile "c:\test.sql" | out-File -filepath "c:\psOutput.txt" --(call this file name MyTest.ps1)
(The above script working if i run manually. I want to run automatic like double click (or schedule with 3rd party tool/scheduler ) in Batch file and see the output in C drive(c:\psOutput.txt))
Can anyone Powershell experts give/suggest full details/steps for this. How to proceed? Is there any configurations required to run automatic?
Thanks in advance.

Testeted the following code and it's working.....thanks all.
Execute sql script using invoke-sqlcmd with batch script and without batch script.
Option1: using Import sqlps
1.Save sql script as "C:\scripts\Test.sql" script in side Test.sql: select name from sys.databases
2.Save Batch script as "C:\scripts\MyTest.bat" Script inside Batch script:
powershell.exe C:\scripts\mypowershell.ps1
3.Save powershell script as "C:\scripts\mypowershell.ps1"
import-module "sqlps" -DisableNameChecking
invoke-sqlcmd -Servername ServerName -inputFile "C:\scripts\Test.sql" | out-File -filepath "C:\scripts\TestOutput.txt"

How to execute .sql file using ODI

Hi All,
I need to execute .sql file using ODI.
I tried @{path}{file} command in ODI procedure selecting oracle technology.but it is failing.
Do any one have any other idea to execute .sql file.
Thanks in advance

Ohk...I think you can try creating batch file(.bat) if its Windows & call that from ODIOSCommand.
The bat file should contain scripts which call .sql file using sqlplus & there you can use @{path}{file} format.
See if this helps.

Santy

Executing sqlldr (sql loader) from java and returning the error code

I'm wandering do sqlldr return any error code whenever it hit error while running in java.
For example, if i run in command prompt using the command below,
C:\ >sqlldr uid/pwd data=abc.dat control=abc.txt
It might give me some indicator that error occurs such as
SQL*Loader-601: For INSERT option, table must be empty. Error on table CURRENCY
or
SQL*Loader-500: Unable to open file (abc.txt)
SQL*Loader-553: file not found
SQL*Loader-509: System error: The system cannot find the file specified.
But when i run in java using the code below,
Runtime rt = Runtime.getRuntime();
Process proc = rt.exec("sqlldr uid/pwd data=abc.dat control=abc.txt");
int exitVal = proc.waitFor();
System.out.println("Process exitValue: " + exitVal);
it will only give me the same exitValue of 1(i presume its error) / 0 (i presume no error) instead of the details of the error.
How can i get the exact error code/message if i were to execute it using java?
Any solution?

mg,
I don't think user576271 wants the exit code, I think [s]he wants the error message.
But wouldn't error messages from SQL*Loader be sent to the stderr stream, and not the stdout stream?
In which case user576271 would need method "getErrorStream()" of class java.lang.Process, no?
Good Luck,
Avi.

SQL Loader and Java

Hi,
I am using a Java Stored Procedure to invoke a SQL Loader process. The RDBMS Version is 8.1.7 on HP-UX 11. I invoke the procedure by calling: exec runcommand('sqlldr user=scott/tiger@orcl control=/home/mydir/ctlfile.ctl log=/home/mydir/logfile.log direct=true errors=550')
where runcommand is the name of the java stored procedure.
The SQL Loader process returns a value of 3 which is the return value for an Operating System Error. I am unable to find any errors related to the Operating System. Is there any particular environment variable which needs to be set before running the process.
I was able to run the same Java Stored Procedure on Personal Oracle on Windows XP without any problems.
TIA,
Ramesh

Hi,
Make sure that the path for data file in control file is correct.
Then it serves your purpose.
Otherwise, give full path to "sqlldr", then run it.
Please let me know the result.
Thanks

Problems with SQL*Loader and java Runtime

Hi. I'm trying to start SQL*Loader on Oracle 8 by using Runtime class in this way:
try{
Process p = Runtime.getRuntime().exec( "c:\oracle\ora81\bin\sqlldr.exe parfile=c:\parfile\carica.par" );
/*If i insert this line my application never stops*/
p.waitFor();
}catch( Exception e ){
. I have seen that if lines to insert are less then 400 all works very fine, but if lines number is greater than 400, all data go in my tables but my log file is opened always in writing.Can anyone tell me why?
Thanks

Just a note if the executable "sqlldr.exe" does not stop (quit running) by itself the p.waitFor() will wait for ever.

Calling SQL LOADER From Java Program

Hi
I need to invoke sql loader from inside a Java Class.
Any Pointers in this regards will be really appreciated.
Thanks
Vishal

You can create two different files which has sqlldr command defined....
1. loader.sh
2. loader.bat
and in the depending on the OS execute one...
         String command = "";
         if(System.getProperty("os.name").equals("Windows 2000")){
                //if os is windows 2000 then execute bat file
                 command = <<bat file path>>
          }else{
                  command = <<shell path>>
          Runtime rt = Runtime.getRuntime();
          Process p = rt.exec(command);
          int i = p.exitValue();
