Calling Batch files in PLSQL Procedure

Hi all,
I am working on a PLSQL procedure and having issues when I am trying to call a batch file.
Issue:-
I have a procedure which have to kick off a batch file. And that batch file needs to run in Windows not in Unix box.
Can someone please help me out in providing some samples or anything?
Thanks a lot in advance.

Thank you rp0428 and sb92075,
I have tried to create a sample of what I am trying to get and so I have created the following code in a batch file and named as Check.bat:-
@set a=3
@set b=4
@set /a c=%a%+%b%
echo %c%
So based on those links you guys provided I have created an
Scheduler Job:-
BEGIN
DBMS_SCHEDULER.create_job (job_name        => 'MYJOB1',
                           job_type        => 'EXECUTABLE', JOB_ACTION      => 'c:\Check.bat', enabled         => TRUE,comments        => 'runs Check.bat' );
END;
And the following Procedure :-
CREATE OR REPLACE PROCEDURE execute_bat_file
IS
BEGIN
   DBMS_SCHEDULER.RUN_JOB ('MYJOB1', TRUE);
END execute_bat_file;
And used the following exec command:-
exec execute_bat_file;
I am getting the following error:-
Error starting at line 1 in command:
exec execute_bat_file
Error report:
ORA-27475: "ACTUATE.MYJOB1" must be a job
ORA-06512: at "SYS.DBMS_ISCHED", line 150
ORA-06512: at "SYS.DBMS_SCHEDULER", line 441
ORA-06512: at "ACTUATE.EXECUTE_BAT_FILE", line 4
ORA-06512: at line 1
27475. 00000 - "\"%s.%s\" must be a %s"
*Cause:    An object of the wrong type was specified. For example, a table
           could have been passed to the drop_job() procedure.
*Action:   Reissue a different command applicable to this object type or
           reissue the same command using an object of the valid type.
Can you guys please help with this?
Thank you once again

Question about calling batch file by using the System Exec+.vi?

Hi
I have a problem about calling batch file. I know that the system exec is equivalent to "run" in Windows. I called the batch file c:\rtxdos\bs\ch0.bat successfully in the "run" but it didn't work in the LabVIEW program. The dos prompt had an error message "Bad command or file name" and it just happen when I call this batch file in LabVIEW. Why?
Bill.

Hi,
Try to set the "working directory" parameter of System exec.vi to the directory where the batch file is located. It may help.
Good luck.

Calling java classes from plsql procedures

I'm attempting to call java classes from plsql procedures which will create cmsdk users, folders, groups etc, however when I attempt to load a java class into the oracle schema using the command:
loadjava -user user/password@database -resolve classname.class
It generates error messages to the effect that classes (cmsdk classes) required by the class cannot be found. The class is loaded and marked with the status "invalid". Is it therefore necessary for me to load the cmsdk packages into the schema?
Cheers
David

Using CMSDK Java API within the database has never been supported
(see Problems loading IFS's java class into database
When we needed to invoke CMSDK code from our PL/SQL code, we used one of two approaches:
(1) use advanced queues to send requests to an external Java program (the CMSDK code, running outside the database) and receive the results back (asynchronous choice); or
(2) make an HTTP request to a Java servlet (the CMSDK code, running in some Java web container like iAS) and get the response back in some custom format (XML or something) (synchronous choice).
It seems to me that the CMSDK Java API was designed to be used only in middle-tier, not in database tier.

Daniel.

Calling batch file from java Program

I have made the java program in which i have called the batch file.But the problem is this that when i call batch file locally it executes normally but when i try to execute batcvh file from remote machine it doesn't runrather it gives Runtime IO execption.Error123.Can anyone provide me the solution for this?

Not without a lot more information. Like for example how you are trying to execute this remote batch file, the code you are using to do that, what kind of server you have no the remote machine to let you remotely execute code, and so on.

Email text files through plsql procedures

Hi,
I have written a procedure that selects table data and writes a .txt file in delimitted format. After the file is created on the C drive of the server I want to attach the file in a email and send it to the recepients.
I have used the built in package and can send emails...but it goes with out the attachment...
Can anyone tell me how can i attach the .txt file in the plsql procedure that sends the email.??

Don't - why write data externally and then have to read that data again to use it internally?
An attachment in an e-mail is not a separate file - the file contents is part and parcel of the e-mail message body. It is a single block of data. There is no requirement for the so-call attachment to be a physical file at all. All that is needed is correctly formatting the main body (as per MIME specs).
So rather write data to a CLOB and when done, create the e-mail body and append the CLOB contents to the e-mail.
This topic has been discussed numerous times. See {message:id=3963129} and {message:id=3913513} for starters.. and consider using the search function before asking a question.

Calling sql script in plsql procedure

Hello,
I have a sql script named mytest.sql and i want to execute this from a stored procedure.
following is the contents of this script
spool d:\mytestsql.txt
select * from tab;
spool off
Actually i want my sql script to run daily to export some tables data.
I can execute this script from a sql prompt but i want to run it from enterprise manager.
I am using oracle 10gR2 on windows2000 system.
Any idea about scheduling the sql script to run automatically??
How to execute this sql script from a plsql procedure??
Thanks

Hi all,
Thanks for all the replies. I have found the solution with external procedures.
Following is the complete step by step guide.
1. Create the OSCommand Java Class using the following statement:
connect as any user:
create or replace and compile java source named oscommand as
import java.io.*;
public class OSCommand{
public static String Run(String Command){
try{
Runtime.getRuntime().exec(Command);
return("0");
catch (Exception e){
System.out.println("Error running command: " + Command +
"\n" + e.getMessage());
return(e.getMessage());
2. Create the following Wrapper Function using the following statement:
CREATE or REPLACE FUNCTION OSCommand_Run(Command IN STRING)
RETURN VARCHAR2 IS
LANGUAGE JAVA
NAME 'OSCommand.Run(java.lang.String) return int';
3. connect as sys
Execute dbms_java.grant_permission( 'FKHALID','SYS:java.io.FilePermission', '<<ALL FILES>>','execute');
execute dbms_java.grant_permission( 'FKHALID','SYS:java.lang.RuntimePermission', 'writeFileDescriptor', '*' );
execute dbms_java.grant_permission( 'FKHALID','SYS:java.lang.RuntimePermission', 'readFileDescriptor', '*' );
commit;
note: here fkhalid is the oracle user.
connect as fkhalid user:
Declare
expdp_cmd Varchar2(2000);
Begin
expdp_cmd := OSCommand_Run('cmd /c sqlplus fkhalid@mtcedwt/pwd @d:\ORA_DUMPS\mydbexp.sql');
DBMS_OUTPUT.Put_Line(expdp_cmd);
End;
In Unix
Set Serverout On
Declare
x Varchar2(2000);
Begin
x := OSCommand_Run('/home/test/myoscommand.sh')
DBMS_OUTPUT.Put_Line(x);
End;
I will check the dbms_scheduler also and will let you know the results.
Thanks

Oracle BI 11.1.1.7.1: Calling BI webservices from Plsql Procedure: ORA-29532: Java call terminated by uncaught Java exception: java.lang.NoClassDefFoundError

Hi,
     I have a requirement of calling BI webservices from Plsql stored procedure. I generated all my wsdl java classes and loaded them into the database. However, when I tried to call one of my java class using stored procedure, it is giving me"ORA-29532: Java call terminated by uncaught Java exception: java.lang.NoClassDefFoundError".
*Cause:    A Java exception or error was signaled and could not be
           resolved by the Java code.
*Action:   Modify Java code, if this behavior is not intended.
But all my dependency classes are present in database as java class objects and are valid. Can some one help me out of this?

Stiphane,
You can look in USER_ERRORS to see if there's anything more specific reported by the compiler. But, it could also be the case that everything's OK (oddly enough). I loaded the JavaMail API in an 8.1.6 database and also got bytecode verifier errors, but it ran fine. Here are the errors I got when loading Sun's activation.jar, which ended up not being a problem:
ORA-29552: verification warning: at offset 12 of <init> void (java.lang.String, java.lang.String) cannot access class$java$io$InputStream
verifier is replacing bytecode at <init> void (java.lang.String, java.lang.String):12 by a throw at offset 18 of <init> void (java.lang.String, java.lang.String) cannot access class$java$io$InputStream
verifier is replacing bytecode at <init> void (java.lang.String, java.lang.String):18 by a throw at offset 30 of <init> void (java.lang.String, java.lang.String) cannot access class$java$io$InputStream
verifier is replacing bytecode at <init> void (java.lang.String, java.lang.String):30 by a throw
Hope this helps,

Calling batch file using dbms_scheduler

Hello,
i have created a schedule, program and a Job to using the DBMS_SCHEDULER. creates all those fine but when i try to run i get errors.
here is the code:
begin
dbms_scheduler.create_schedule(
schedule_name => 'dailyjob',
repeat_interval => 'FREQ=DAILY; INTERVAL=1;
BYDAY=TUE; BYHOUR=4',
comments => 'schedule to run daily');
dbms_scheduler.create_program
( program_name => 'runord',
program_type => 'EXECUTABLE',
program_action => 'd:\oracle\product\admin\scripts\ord.bat >nul',
enabled => TRUE,
comments => 'ORDERS.'
dbms_scheduler.create_job (
job_name=>'TEST',
program_name =>'runord',
schedule_name=> 'DAILYjob',
enabled => true,
comments => 'TESTING the Orders Job.'
end;
exec dbms_scherduler.run_job('TEST');
gives me the errors.
in the batch file i am calling connecting to the database and calling the sql file. is there any way that i can connect to the database directly from scheduler itself? i dont like to save username and passwords in a file to connect and invoke sqlplus?
could any one help.....

Pass them to the external command line as parameters? That exposes the name and password even more.
We use a tightly controlled directory with this information in it and access to the directory is controlled. The scripts are also in a controlled directory and have read privileges where the credentials are stored.
That way the scripts don't have the data exposed and don't use it until they run.

Powershell script calling batch file, how to "echo" or otherwise pass in two or more values asked for by batch file

I've been having a lot of problems trying to get an old batch file we have laying around, to run from my powershell script. The batch file actually asks for two inputs from the user. I've managed to put together a powershell that echos a response, but of
course, that only will answer one of the prompts. As usual, I've simplified things here to get my testing done. The batch file looks like this:
@ECHO OFF
SET /P CUSTID=Customer Number:
SET /P DBCOUNT=Number of Live Databases:
ECHO Customer Id was set to : %CUSTID%
ECHO Database Count was set to : %DBCOUNT%
Two inputs, two echos to verify values have been set. Now, the powershell looks like this:
Param(
[string]$ClientADG,
[string]$ClientDBCount,
[scriptblock]$Command
$ClientADG = '1013'
$ClientDBCount = '2'
$Response = $ClientADG + "`r`n" + $ClientDBCount
$Command = 'Invoke-Command -ComputerName localhost -ScriptBlock {cmd /c "echo ' + $ClientADG + ' | E:\Scripts\Setup\Company\DatabaseSetupTest.bat"}'
powershell -command $Command
Output looks like:
Customer Number: Number of Live Databases: Customer Id was set to : 1013
Database Count was set to :
As expected, as I'm only passing in one value. I can't figure out how to get a second value passed in for the second prompt. Instead of $ClientADG, I tried to mash the two value together in the $Response variable with a cr/lf or a cr or a lf in between,
but no go there either. The first input gets set to the second value, and second input is blank still. In the essence of time, I need to get this batch file called from Powershell to get some folks productive while I actually rewrite what the batch file does
in another powershell, so it can be integrated into other things. (I'm automating what a bunch of people spend hours doing into multiple scripts and eventually one BIG script so they can focus on doing their real jobs instead).
How do I get this right in powershell? I don't want to modify the batch file at all at this point, just get it running from the powershell.
Thanks in advance!

It's a "simple" test so I can figure out how to get the arguments passed from ps to bat. The bat file looks like this:
@ECHO OFF
SET CUSTID = %1
SET DBCOUNT = %2
ECHO Customer Id was set to : %CUSTID%
ECHO Database Count was set to : %DBCOUNT%
That's it. The PS script looks like this:
Invoke-Command-ComputerName myserver-ScriptBlock{cmd/c"E:\Scripts\Setup\Company\DatabaseSetupTest.bat
1013 2"}
That's it. The bat file exists on "myserver", and I'm getting the echo back, but without the values.

Call batch file using IBOT

Hi ,
We are using OBIEE 10G
and I need to transfer folder from one machine to another machine(both are windows) so I have written a dos command (batch file). Now I need to call this batch file from IBOT ,how I can do this. any suggestion pls.

Hi ,
U can use a javascript to call the batch file and attach the script to your IBOT :
For example :
<html><head><script type="text/javascript">function runApp(st) { WshShell = new ActiveXObject("WScript.Shell"); WshShell.Run (st,1,false);}</script></head><body><font onClick="runApp('file://c:/winnt/notepad.exe');" style="cursor: hand;"><u>Notepad</u></font><br>Batch File</body></html>

Call Batch file

I have an JMS Subscriber that I'd like to have respond to a request by publishing to a different topic - I've setup batch files for the proof of concept - HOW DO I CALL A BATCH FILE from a java class ?

Like this:
import java.io.*;
public class RunProcess {
public static void main(String[] arg) {
    try {
      Process myProcess;
      myProcess = Runtime.getRuntime().exec("cmd /c mybatch.bat");
      String s = null;
      DataInputStream in = new DataInputStream(
                           new BufferedInputStream(
                               myProcess.getInputStream()));
      while ((s = in.readLine()) != null) {
        System.out.println(s);
      System.exit(0);
    catch (IOException e) {
      System.out.println("Exception: "+ e);
      System.exit(-1);
}The InputStream/read is to display command o/p. Not absolutely necessary.

Executable-Job to call batch-file

Dear NG!
I'm currently using Oracle 10.1.0.4 on a MS Windows Server 2003 and
I've got some problems concerning EXECUTABLE-Jobs in DBMS_SCHEDULER.
I just want to PIPE OUT the results of my Batch-Execution in a LOG-File,
but ORACLE just returns an error code.
Here's my example:
the Batch-File "TEST.bat" contains:
dir c:\temp >c:\temp\content.log
the SCHEDULER-Job to run in PL/SQL:
BEGIN
DBMS_SCHEDULER.CREATE_JOB (
JOB_NAME =>'TEST1',
JOB_TYPE =>'executable',
JOB_ACTION =>'c:\temp\TEST.bat',
ENABLED => TRUE,
AUTO_DROP => TRUE
COMMIT;
DBMS_SCHEDULER.RUN_JOB('TEST1');
END;
the LOG-Message:
ORA-27369: Job vom Typ EXECUTABLE nicht erfolgreich mit Exit-Code: Unzul¿ige Funktion.
I also tried the following JOB_ACTION-Parameter:
- 'c:\windows\system32\cmd.exe /q /c c:\temp\TEST.bat'
or
- 'c:\windows\system32\cmd.exe /q /c c:\temp\TEST.bat >Nul'
or
- 'dir c:\temp >c:\temp\content.log'
or
- 'c:\windows\system32\cmd.exe /c /q dir c:\temp >c:\temp\content.log'
...but I had no success.
I already read the posts in the forums about that but I did not found any solution.
Could someone please tell me where my mistake is?
A rapid response would be appreciated!
Thanks in advance!
Dirk

You may be hitting bug 3663347 - WIN32/SCHEDULER: EXECUTABLE JOB FAILS WITH 'ORA-27369: THE HANDLE IS INVALID', which should be fixed by Patch 4287619.

Call sql file from plsql

Hello,
I am stuck for many days in this issue. Hope someone helps me out.
I am using Oracle 11.
I am writing an utility of Purging the data from the database base on certain criteria.
We don't have physical(actual) partitions present on our system(since we are not using enterprise edition).
We have 57 tables representing 57 partitions. Then we are creating a view of all these 57 tables -
CREATE or REPLACE VIEW MY_VIEW AS
select [column_names] from table1
UNION ALL
select [column_names] from table2
UNION ALL
select [column_names] from table3
UNION ALL
select [column_names] from table57
This upper query is saved in the 'body' of user_views.
Now when a user wants to delete a partition--
-I am reading this query body in .sql file.
-Editing the .sql file ie removing the unwanted 'select * from tablen'
-Dropping the View.
-Recreating the view from the edited .sql file.
The issue is in creating the view on the fly from the procedure--
- I cant do EXECUTE IMMEDIATE 'CREATE VIEW...' and 'DBMS_SQL.PARSE' as the query body is longer than 32767 characters.
So i chose the option to do file write. In the file I write the VIEW query and then I want to create the View from this file.
Now i am not able to call the .sql which contains
CREATE OR REPLACE VIEW MYVIEW AS
select...
UNION ALL
select...
select...
The character length of this file is around 90000.
Please guide me in this issue.
Any new idea to manage the very large View in runtime is also welcome...
Thank You in advance
Vaib
arge View in runtime is also welcome...
Thank You in advance
Vaib

As it's 11g, even better would be to use EXECUTE IMMEDIATE as Solomon suggested. It can handle CLOBs.
If it were 10g, then fair enough use the DBMS_SQL package with something like...
