Execute process (shell script) under different user

Hi,
is it possible to use the ProcessBuilder oder .exec()-method to execute a shell script under a JVM-different user? I need to start shell scripts for different system users and I don't want to use SUDO or a wrapper script to switch to the required user. I would like to define the user at java level. Is this possible?
Best regards,
Thomas

looking for something like this too.
currently i am relying on a script in which i have to set the user as:
"su username -c java_program"
the problem with this approach is that if youre not running as root, then su asks for a password, thereby halting execution. (tried input redirects and here-docs, (some popular linux tricks), they did not work)
so you have to be root for the script option to work.
if anyone can suggest a more "java based" way of executing a process as a different user , thatll be awesome.

DSC powershell xwindowsprocess to execute batch file under different user account

DSC powershell run under "NT AUTHORITY\SYSTEM".
I am trying to execute a batch file under different user account using xwindowsprocess in DSC resource kit.
I created a custom dsc resource with 3 parameters namely Exepath, Arguments, Credential.
I received those parameter values in settargetresource method.
CallPInvoke
[Source.NativeMethods]::CreateProcessAsUser(("$ExePath "+$Arguments), $Credential.GetNetworkCredential().Domain, $Credential.GetNetworkCredential().UserName, $Credential.GetNetworkCredential().Password)
I tested it by invoking a batch file and writing username under which it executes to a text file.
After executing, the output text file still contains the "Systemname$".

Executing a shell script from a java program

Hi,
I'm facing a problem while executing a shell script from a jsp page.
I'm using exec() function.
It's working fine for single statement scripts.But if the script consists of any database processing and some other processing statements,it's not returning the correct exit status of the process.
Will u please help me in this.
If there is any other ways to execute a shell script from a jsp page other than Runtime.exec().If so let me know.
Thanks in advance.

I think this shud workMaybe - but it is wrong! Why do you create aReader
and then read bytes which are turned into a String
without worrying about whether or not the bytes area
String and without worrying about the character
encoding if the bytes do represent characters and
without worrying about how many bytes wereactually
read.
Also, both you and the OP should read, digest and
follow the advice given in
http://www.javaworld.com/javaworld/jw-12-2000/jw-1229-
traps.htmlI dont care if it is wrong. This code works for me.
We are here to solve problems not to find which post
is wrong.It is wrong! You are posting bad advice that is very wrong! It may work for you but it is wrong in general! WRONG WRONG WRONG.
If you have a solution then post it I did post a solution! The reference I gave will explain to you and the OP exactly how it should be done.
rather then
posting rude comments.I was not rude! I was explaining just some of what was wrong!

Hello,
It's hard to help you but what you can do is listening to the outputs of your script, you should read the output stream and error stream and send them to the default console.

Error while executing unix shell script from java program

Hi All,
I am trying to execute unix shell script from a java program using Runtime.execute() method by passing script name and additional arguments.
Code snippet :
Java Class :
try{
     String fileName ="test.ksh";
     String argValue ="satish"; // value passed to the script
     String exeParam = "/usr/bin/ksh "+fileName+" "+argValue;
     Process proc = Runtime.getRuntime().exec(exeParam);
     int exitValue = proc.waitFor();
     sop("Exit Value is : "+exitValue);
catch(Exception e)
e.printStackTrace();
}Test.ksh
export -- application realated paths..
nohup abc.exe 1> test.log 2>&1;
$1
exit.By running the above java class , i am getting exit Value: 139 and log file test.log of 0 bytes.
when i am running the same command (/usr/bin/ksh test.ksh satish) manually, it's calling abc.exe file successfully
and able generate the logs properly.
Pls let us know where exactly i am stuck..
Thanks in advance,
Regards,
Satish

Hi Sabre,
As per the guidelines provided by the article, i had done below changes..
InputStream is = null;
InputStreamReader iStreamReader = null;
BufferedReader bReader = null;
String line = null;
try{
String fileName ="test.ksh";
String argValue ="satish"; // value passed to the script
String exeParam = "/usr/bin/ksh "+fileName+" "+argValue;
Process proc = Runtime.getRuntime().exec(exeParam);
is = proc.getErrorStream();
iStreamReader = new InputStreamReader(is);
bReader = new BufferedReader(iStreamReader);
System.out.println("<ERROR>");
while((line = bReader.readLine()) != null)
System.out.println("Error is : "+line);
System.out.println("</ERROR>");
int exitValue = proc.waitFor();
sop("Exit Value is : "+exitValue);
catch(Exception e)
e.printStackTrace();
Now , it's showing something like..
<ERROR>
</ERROR>

Node Manager starting managed servers under different users

Hi all,
I have multiple domains running on the same server.
Is it possible to get node manager to start managed servers from different domains under different users?
Default is the user under which node manager was started originally.
Thanks
Arnaud

Oracle documentation is still in confussion state for Unix platform nodemanager.
NodeManager Admin Guide had chapter 3 for General configuration of nodemanger. Chapter 5 is for script based nodemanager.
In chapter 5 there is clear way defined for " Starting a node manger for Unix machine".
chapter 3 is mess there is clear-cut direction to reach the remote startup of servers.
Why we have so many types of nodemanager for connect. howbout start them?
Can someone expert in Oracle WebLogic please respond to this.
*Nodemanagers are NOT meant for multiuser development env.
They are defined for production env and for HA, FailOver.*

Terminal is trying to auto-execute a shell script

I can no longer use Terminal because every time I try to start it, it automatically runs a shell script I used to have on my desktop and then immediately says "[Process Completed]." I'm not sure how exactly I got it to do this... as far as I know all I did was execute the shell script by associating it with Terminal and double clicking it... but now I can't create a new shell without it automatically attempting to execute it. Please help!
Thanks,
Michael

Executing a shell script with DBMS_SCHEDULER

Hi,
when I execute a shell script with DBMS_SCHEDULER this doesn't works correctly
BEGIN
DBMS_SCHEDULER.create_job
job_name => 'job_AR',
job_type => 'EXECUTABLE',
job_action => '/home/crm/crmdw/AR/start_execution.sh',
enabled => TRUE,
start_date => systimestamp,
repeat_interval => 'FREQ=MINUTELY;INTERVAL=15',
comments => 'Test Job AR'
END;Inside the shell script there is a code who call a Hierarchy of process,
if I executed it manually or with a cron, it works perfectly
but when I execute it with the job that I've described before it's executes
all process at same time and it doesn't work.
What can I do to fix the issue,
any Ideas?

Executing Unix shell scripts with DBMS_SCHEDULER

I have the following Unix shell script create_backup_file.sh:
#!/usr/bin/ksh
/usr/bin/ssh [email protected] /usr/bin/touch/app_home/home/trotestbat/scripts/TRO_batch_complete_`date +%d-%m-%Y-%H%M`
If I execute this from the command prompt it creates the file on the remote server.
I've used dbms_scheduler to try and execute this from Oracle:
BEGIN
SYS.DBMS_SCHEDULER.CREATE_PROGRAM
program_name => 'CREATE_TRO_BACKUP_FILE'
,program_type => 'EXECUTABLE'
,program_action => '/APP/TORPEDO/DTE/SCRIPTS/create_backup_file_tro.sh'
,number_of_arguments => 0
,enabled => TRUE
,comments => NULL
SYS.DBMS_SCHEDULER.CREATE_JOB
job_name => 'DTE.TESTAGAIN'
,start_date => TO_TIMESTAMP_TZ('2010/05/17 16:09:24.710789 +01:00','yyyy/mm/dd
hh24:mi:ss.ff tzh:tzm')
,repeat_interval => NULL
,end_date => NULL
,program_name => 'DTE.CREATE_TRO_BACKUP_FILE'
,comments => NULL
END;
The problem I have is that scheduler executes the shell script and creates the file but it never completes the job. The status of the job is permanently 'RUNNING'. Why is the scheduler not returning a completed status?

the "infinite" script is usually caused by a prompt (script pauses for a user input).
Please keep in mind that executing script via scheduler is not the same as manually via prompt.
1. the script runs as ORACLE user ID (or whatever you specified using DBMS_SCHEDULER.create_credential or/and "$ORACLE_HOME/rdbms/admin/externaljob.ora")
2. the environment variables are probably not the same.
My wild guess is that you never ran SSH using "oracle" UID and thus it prompts for permission to add the remote computer’s fingerprint to the user’s ~/.ssh/known_hosts file - since it is a script, it just hangs and waits for input.
Did you try to login to unix box as oracle uid and run the script manually?

CSS 11500 - Keepalive script to remotely execute a shell script on a server

Hi!
I've been trying to connect the dots but so far I've got nothing close to what I need - based on Cisco's documentation.
I was wondering if it was possible for the CSS switch to connect to a server in order to execute a shell script such as "/opt/whatever/script.sh", which would return a specific value like "OK". Anything different than OK would mean a dead service, and the affected service would be taken out of business (no load balancing play).
Could someone confirm whether it can be done?
Many thanks!!
Leo

Leo,
you could try to use CSS script to telnet to the server, and execute the command.
But that would be ugly.
What you should do, is put your script inside a cgi webpage and let the CSS call the webpage.
Your webserver will then run the script that you want and return to result inside and HTML page to the CSS which can then decide on the status of the server.
If you do not have a web server, you should create a small tcp server to listen to CSS request and again send the result of the script back to css.

What is better a shell script or a user exit?

Hi experts!
I need to change the owner of a file when I send it to XI sever.
I talk with the administrator of the system to change the owner with a shell script but he tell me that is better if I use a user exit. But my question is: What is better? The shell script or the user exit?

hi,
>>>>I talk with the administrator of the system to change the owner with a shell script but he tell me that is better if I use a user exit
maybe because the admin does not do the user exits ?
you can do it with XI but you'll have to create it
via a proxy for example (as standard file adapter does
not support this)
on the other hand the file adapter supports invoking
system commands (so you can start a shell script)
I'm not directly answering your question
I'm just telling you what you'll have to do
to build your solution in both cases
