How to run SQLLDR Command in java

Hi All,
I want to upload large amount of data in to a table using SQL Loader and i am using SQLLDR command in command prompt. i need to automate the process because i have to do 2 to 3 times a day manually.
i have tried the below code inside the main method, but it is not working
Runtime rt = Runtime.getRuntime();
Process proc = rt.exec("SQLLDR idm/idm@idmdev control=E:\\SAP_HR\ttsldata.ctl");
I have Control file and CSV Format data with me. While trying in command prompt it is working but not using java. Please help me to finish this.
Thanks in Advance!!!!

Sorry for that, SQLLDR means SQL Loader command to upload the data in to the database. Please let me know how to do it.

How do run unix command in java

hi
All unix command working fine in our java program.
but i want change user in linux by using java. it's not working.
"su root" This command onely not working.
anybody know help me
This is my ID [email protected]
This my code
<% String s = null;
try{
Process p = Runtime.getRuntime().exec("su root");
BufferedReader stdInput = new BufferedReader(new
InputStreamReader(p.getInputStream()));
BufferedReader stdError = new BufferedReader(new
InputStreamReader(p.getErrorStream()));
out.println("Here is the standard output of the command:\n");
while ((s = stdInput.readLine()) != null)
out.println(s);
catch(Exception e) {}
%>

I don't have further info to add to your first post, but think your guess seems quite reasonable. I thought of starting a new thread on the same topic, but think this (question) fits in here, too.
I have Java code (freeware, not opensoure), intended for Unix, which basically provides the graphical interface and relies on an I/O layer (C + shell scripts) to do most of the work. I have access to the C+shell scripts which are opensource. I ported it to Cygwin and want to use it under Windows (there is no Cygwin native Java VM).
My problem now boils down to " how to run commands under Unix and what differences are there with Windows". What are the variants?
I have to guess what the program is doing when I get an IOException at some point. E.g.: a call to shell script may be made in a different way as to a compiled exe in Unix?. I found a way to bypass path problems because forward slashes are also accepted and /cygdrive/c construct can be replace by c:/; shell scripts can be compiled into exes using shc and they work; if symbolic links are replaced by duplication of exe files, they work. What will happen in an instance whereby a process runs a shell script dynamically, through a pipe (the shell script is compiled in the Cygwin/win version and receives parameters) in a construct like:
pipefp = epopen(cmdbuf,"w"); /* (cmbuf is "makehdr par1 par2 ... ") (makehdr was a shell script and is now compiled exe for Cygwin/Windows) */?.
Thanks.

How to run system commands from JAVA

Hi Friends,
How to run windows system commands from JAVA
Runtime r=Runtime.getRuntime();
r.exec("dir");
Throwing following Exception
CreateProcess :dir error=2
Thanks in advance
Hamsa

Hi ,
in Windows NT this is not possible, you can use the following :
Runtime r=Runtime.getRuntime();
StringBuffer sbuf = new StringBuffer();
String dir = new String();
java.lang.Process proc = r.exec("cmd /c dir");
InputStream is = proc.getInputStream();
int ch ;
while((ch=is.read() ) != -1)
sbuf.append((char)ch);
is.close();
dir = sbuf.toString();
System.out.println(dir );

How to execute Linux command from Java app.

Hi all,
Could anyone show me how to execute Linux command from Java app. For example, I have the need to execute the "ls" command from my Java app (which is running on the Linux machine), how should I write the codes?
Thanks a lot,

You can use "built-in" shell commands, you just need to invoke the shell and tell it to run the command. See the -c switch in the man page for your shell. But, "ls" isn't built-in anyays.
If you use exec, you will want to set the directory with the dir argument to exec, or add it to the command or cmdarray. See the API for the variants of java.lang.Runtime.exec(). (If you're invoking it repeatedly, you can most likely modify a cmdarray more efficiently than having exec() decompose your command).
You will also definitely want to save the returned Process and read the output from it (possibly stderr too and get an exit status). See API for java.lang.Process. Here's an example
java.io.BufferedReader br =
new java.io.BufferedReader(new java.io.InputStreamReader(
Runtime.getRuntime().exec ("/sbin/ifconfig ppp0").
getInputStream()));
while ((s = br.readLine()) != null) {...

Running DOS command from JAVA

Hi ,
I would appreciate if anyone could tell me how to run DOS command such as "del" using JAVA language .Thank you.

<steps onto soapbox>
Surely for something like 'del' we should be advocating a non-OS specific method so we don't lose sight of Java's cross platform abilities.
If it has to run an OS specific thing fine, but please look for a non OS specific solution first.

Running ls command from Java stroed procedure no output

Hi ,
I am trying to run ls command from java stored procedure in oracle
Process p = Runtime.getRuntime().exec("ls");
BufferedReader stdInput = new BufferedReader(new
InputStreamReader(p.getInputStream()));
BufferedReader stdError = new BufferedReader(new
InputStreamReader(p.getErrorStream()));
// read the output from the command
System.out.println("output of the command run:\n");
while ((s = stdInput.readLine()) != null) {
System.out.println(s);
from java stored procedure in oracle.
i get output of println statments but it does not go into while loop to print from stdInput.
Result of running Java stored procedure is -
output of the command run:
Call completed.
when i run the program on client side it works fine.
Has anybody tried this from java stroed procedure.
Thanks,
Jag

Jag,
Actually, the question of whether it works for me seems to depend on the version of the OS (or Oracle). On RedHat Linux (Oracle 8.1.6) it didn't work at all, but on Solaris (Oracle 9.0.2) it did. Here's the output from that run:
SQL> /
output of the command run:
init.ora
initDBPart9i.DBPSun01.ora
initdw.ora
lkDBPART9I
orapw
orapwDBPart9i
spfileDBPart9i.ora
Done
PL/SQL procedure successfully completed.
But, I did need to change a line of your code to this:
Process p = Runtime.getRuntime().exec("/usr/bin/ls");
your original was:
Process p = Runtime.getRuntime().exec("ls");
You might consider, if possible, use of some of the Java File classes instead of ls, as this might make things more predictable for you. There were some examples in oramag.com a few months ago, but they were pretty simple (you might not need them).
Hope this helps,

How to call gnuplot command from java

Hi there,
In our course, we are required to develop an GUI for gnuplot. In case you don't know about gnuplot, it's a plotting program and has lots of command. We want to use java and swing, but now we don't know how to call gnuplot command from java, or how to execute a shell command(script) from java.
By the way, since we need read in files with several columns of data and allow user to select a column, we want to use JTable. Is that reasonable?
Thanks a lot for any suggestions!
Jack

Hi, there:
Will using JTable add much overhead? I may have to use several JTables and switch among them. I can add scroll bar to or edit JTables, right?
BTW, do you have experience about gnuplot? Can I find the command tree of gnuplot somewhere? Or do you know a better place to post question about gnuplot? unix/linux group, maybe.
Thanks,
Jack
P.S. Would you guys answer my question after I use up my duke dollars? :- )

Try this:

InputStream stream = proc.getInputStream();
InputStreamReader isr = new InputStreamReader(stream);
BufferedReader br = new BufferedReader(isr);
String line = null;
while ( (line = br.readLine()) != null) .....
