Has Oracle come up with the feature of executing OS commands within stored procedures yet?
Anyone aware of such thing?
Thanks.

I have a Java routine that will do this in UNIX.
Let me know if you want the code and send me an email to [email protected]

hi all..
i want to execute operating system commands from PL/SQL..
particulary imp command....
i have used the f/wg approach but while i execute the imp command it does not responds me any output..
I have to kill the process from o/s.
prodn is my user

java source named "Util"

try
Process p = rt.exec(args);
int bufSize = 4096;
BufferedInputStream bis = new BufferedInputStream(p.getInputStream(),
bufSize);
int len;
byte buffer[] = new byte[bufSize];
// Echo back what the program spit out
while ((len = bis.read(buffer, 0, bufSize)) != -1)
System.out.write(buffer, 0, len);

finally
return rc;

create or replace procedure RC(p_cmd in varchar2)

begin
x := run_cmd(p_cmd);
end;
i executed the command as follows in sql>
BEGIN
rc('/oracle/product/9.2.0/bin/imp tim/tim file=/home/oracle/vas4359.dmp log
=log1.log');
END;
it runs fine creates log1.log in / home/oracle but there is no output in
log1.log file.
I have to kill the process as follows after which sql> displays me :
"PL/SQL procedure successfully completed."
[oracle@msebdb oracle]$ ps aux|grep imp

Can I use Copy command in Pl/Sql.For example :-
Declare
cursor c1 is select table_name from all_tables
where owner = 'LSP' and rownum = 1;
v1 varchar2(2000);
Begin
for c2 in c1 loop
v1:='copy from lsp/lsp123479@dvlaq to scott/[email protected] create '|| c2.table_name ||' using select * from '||c2.table_name;
execute immediate v1;
end loop;
end;
Its not running properly giving an error as invalid Sql statement .
Is it bcoz Copy command cannot be used in a Pl/Sql Block.Is there any other way to move the Table & data to another Data Base .Database link is the obvious one. And the SQL statement would look something like this (on the target database):
SQL> create table FOO nologging as select * from FOO@sourcedb;
However, the first question I always ask if why? What one may think is the solution to a problem is not always the best solution. So one need to identify the problem first, and then see what solutions there are and which one is the best fit.
Other options are replication (using materialised views for example), Data Pump (available with 10G) - even could be Data Guard, a standby database, or a Real Application Cluster... depending on just what the problem and actual requirements are.
Also important to note that SQL*Plus has its own set of commands. Do not confuse these commands (like EXEC, COPY, CONNECT, HOST etc) with the SQL and PL/SQL Languages. Not only are they executed by different software products, SQL*Plus commands are executed on the client and SQL (and PL/SQL) runs inside the Oracle database instance. -
Is there any way to execute an OS command from pl/sql other than using dbms_pipe & pro*C combo. I have done this way before but it seems there is built-in oracle package which can do this in 8/8i.
Also HOST command in forms will execute the OS coomand from the clinet. Is there any way to execute the OS command on the server from the forms clinet?
thanks,
Ravi.
nullRavi,
Can you send me an example how one can
execute a this command from a PL/SQL
program 'sed 3q /etc/passwd'.

as it seems not to be working in my case
thanx in advance,
Rashaofcourse not

Do you really think when asking twice or more often you will get a quicker answer? -
Hello guys! :)
I need to execute some SFTP commands on the database server to another SFTP server. In oracle forms theres a built in called "HOST" which executes native commands on the server. Is there something similar to that in PL/SQL?
Also, im wondering of each call of the "HOST" command opens a new session in CMD. I'll need to log in, submit files, and retrieve files as well. If the HOST command opens a new session everytime, ill lose the login credentials from the first HOST command.
Anyone know of anything like this thats been done before? Let me know. Thanks.
MoDuplicate thread
SFTP in PL/SQL
Please do not repost if the prior answers don't suit you.
The answer to your question is obviously there is no HOST command in PL/SQL, as there has never been a HOST command, as Oracle happens to be a RDBMS.
You could use the external procedure facility, you could also call Java.
Tom Kyte has an utility for this on http://asktom.oracle.com, called run_cmd

Hi,
Rather the opening a new process (sqlplus), a new connection (need password) etc... I would rather read and execute the file in pl/sql.
I do not know if someone wrote it already, but here is a quick and dirty code for doing that with UTL_FILE.GET_LINE
Here, I am only processing some DML statements and no SELECT statements. Correct it as you like !

vSFile := UTL_FILE.FOPEN(dir_name, file_name,'r');
vCmd := NULL;
IF UTL_FILE.IS_OPEN(vSFile) THEN
LOOP
BEGIN
UTL_FILE.GET_LINE(vSFile, vNewLine);
if (vCmd is null) THEN
if (upper(vNewLine) like 'INSERT%' or upper(vNewLine) like 'UPDATE%' or upper(vNewLine) like 'DELETE%') THEN
if (vNewLine like '%;') THEN
/* we have a single line command, execute it now */
dbms_output.put_line(substr(vNewLine,1, length(vNewLine)-1));
execute immediate substr(vNewLine,1, length(vNewLine)-1);
else
/* we have a command over multiple line, set vCmd */
vCmd := vNewLine;
end if;
else

get
can't exec: /tmp/sri/GROUP_ho.sh lacks user privilege
same error;Process management at the OS level should prevent execution continuing in the calling code until the command has completed (either successfully or with error).
If the low level java code were to spawn child process threads then execution could continue, but I'm guessing the Java function your talking about doesn't do that and just calls the operating system to execute the command and waits for the returning code to come back. -
Hi All,
Can we run DOS Command from PL/SQL Program.
Thanksyou can execute os commands using DBMS_PIPE package. Write a program that reads an Oracle pipe (using C or java) and send messages to pipe in PL/SQL Your C program should read pipe and execute statement in it by using system() command.
