Possible to execute 2 commands in 1 line?

Hi,
is it possible to concatenate 2 commands, i.e. "desc dba_tables" and "select count(1) from dba_tables" in one line and execute them? ...
SQL> desc dba_tables && select count(1)...
or something like that?
I donÂ´t want a script!
THX in advance...
Paul

SQL> desc dba_tables && select count(1)...
is not possible, but you could try
select column_name "Name", decode(nullable,'N','NOT NULL') "Null?", substr(decode(data_type,'VARCHAR2','VARCHAR2('||DATA_LENGTH||')',
'CHAR','CHAR('||DATA_LENGTH||')',
'NUMBER','NUMBER'||decode(DATA_PRECISION,null,null,'('||data_precision||decode(data_scale,0,null,','||data_scale)||')'),
data_type),1,20) "Type"
from dba_tab_columns
where table_name = 'DBA_TABLES'
union all select to_char(null),to_char(null),to_char(null) from dual
union all select ' COUNT(*)',to_char(null),to_char(null) from dual
union all select '----------',to_char(null),to_char(null) from dual
union all select to_char(count(*)),to_char(null),to_char(null) from dba_tables;

Is it possible to execute OS commands/files on remote server using SOA Suite/BPEL , just like we have JCA adapter File/FTP to exchange files across servers ?

I am working on technical process automation requirement wherein files need to be exchanged and executed as well , SOA workflow capabilities are helping but I could not find a way to remote OS comman execution yet.
Please help.
Thanks

The whole idea of SOA is to run web services located anywhere. So I believe if you can expose the runtime in remote servers as services then you will be able to call those services like any other web service.
Or if you requirement is to execute files on the SOA server itself then you can use the java embedding activity.

Execute SQLPLUS command using JDBC

Hi,
I was wondering if its possible to execute sqlplus command (eg set define off, change date format ..etc) using JDBC ?
Can anyone please post me some sample codes about this ?
Any help will be appreciated

Hi,
But the Runtime.exec() and the JDBC application have
their own connection to the database, and the sqlplus
commands that i need to run are session based (only
valid during the connection). eg set define off
How do I overcome this ?
Huh?
You put anything you want into a input file. You feed the input file to sqlplus. If there are results then you put them into an output file.
None of that has anything to do with JDBC nor even with java. When you call Runtime.exec() you are running a completely different process. What you do with that process is up to you.

Execute dir command and get output

Hi,
Is it possible to execute a command such as dir,md or copy using a java prorgam.Plz tell me how to do this.
Thanks a lot,
Chamal.

You can get that dir info from java.io.File.listFiles(), of course.
But if you just want to run OS commands you can do it with java.lang.Runtime:

Execute panel commands

Hello everybody,
is it possible to execute panel commands like Swatches->Add Selected Colors from a Plugin?
If not, has anybody an idea how I could implement this command?
Thanks for any answer!

Hi,
I just tried the same configuration and it works properly. Since you're not using any end of string character, any read operation will return after the specified timeout with the data in the buffer. I don't know what could be happening, but I can give you some testing ideas.
It seems that you are already doing a loopback test. Try doing the test using hyperterminal. Here's a document that describes the process:
http://zone.ni.com/devzone/conceptd.nsf/webmain/D48BA43C59B60277862569EE000501FD?opendocument&node=DZ52363_US
Using hyperterminal will show if there's any hardware or connection problems.
If not already doing it, do a loop backtest with the sample program or the Test panel of the ActiveX control.
Hope this helps.

Executing client commands without using webutil

Hi,
Overview: Our dba is busy enough to be disturbed for configuring webutil for me to execute client commands like client_host, client_text_io, etc.
The forms resides on unix server, then I want to implement a feature that writes data to a file then to be saved in the client's
local directory.
Question: I was just wondering if I can or is it possible to execute client commands specifically windows commands without using client_host?
Any help would be much appreciated.

I think i found a way on how to do it, using Runtime.getRuntime().exec

Execute powershell commands on a VM from the host.

I’m wondering if it’s possible to execute PowerShell commands from the host that will be execute on a virtual machine.
I have around 10 VM and I need to run the same command on all of it and I need to do the same in other 15 host.
None of the VM belong to the same domain.

Yes, it's possible.
It's not recommended to do any administrative tasks from the host. You should remove the GUI and all roles from the host except things related to Hyper-V and used in your environment like Failover Clustering and MPIO.
As a best practice, set a Windows 8.1 VM as your management station and install RSAT tools on it including Hyper-V Manager. It also comes with Powershell modules you need to run Powershell commands and scripts against all your hosts and VMs.
On the machines to be managed by Powershell you need to enable Powershell Remoting. In Server 2012 and above and Windows 8 and above this is enabled out of the box (even core versions). In older versions of Windows
enable Powershell Remoting manually as shown in this post.
On the management Win 8.1 VM that has RSAT installed, if the managed machines belong to the same domain as the managing station, you're good to go. If not, run this command on the managing station:
winrm s winrm/config/client "@{TrustedHosts=""My2003Server,host2,host3,vm4""}"
Execute your scripts against multiple machines by using Invoke-Command as in:
'Computer1','Computer2','Computer3' | % {
$Result = Invoke-Command -Computer $_ -ScriptBlock {
Get-Process
$Result
This example, will execute the commands in the scriptblock on each of the 3 computers in line1, and return the result.

How to run an executable from command-line

I'm learning how to use the Terminal and I got stuck in a silly thing (I suppose it is). How can I run an executable file from command-line in Terminal?
For example: I have a file named "Hello" in the folder /sample. If I use the ls command (ls sample), I can see the file Hello. Then I move to the directory (cd /sample) and try to run the file Hello (typing "Hello") but I got "command not found" message.
If I drag the Hello file from Finder to Terminal and hit Return, it runs perfectly. And if I type the full path to the file (even if I'm already inside its directory), it also runs.
So, my doubt is if there is any command to run an executable from command-line.
Thanks

I took the trouble of reading *man bash* and it explains the issue. to add the current directory to PATH you need to add an empty path to PATH like this
PATH=$PATH::
you can add it to ~/.bash_profile so that it's executed automatically when you start bash. I suspect the linux system you are talking about had this set up by default or had it added to PATH in /etc/profile which defines PATH globally.

Execute Process Task :Executing DOS Command lines in Execute Process Task

Hi All,
I am trying to sftp files using Tectia Client from my local system. For that I have used the Execute Process Task in SSIS. First I open DOS command and try to instantiate the sftp3.exe.
Then I write down the below command
binary
open username@hostname
lcd C:\Test
cd <Destination Path name>
put test.txt
How to execute the command in execute process task ?
help is appreciated
Thanks

Hi ConnectDebz,
According to your description and script example, do you use WinSCP.exe to perform the SFTP files transfer? If so, you should set the Executable of the Execute Process Task to the path of the WinSCP.exe, save the script in a .txt file and set the Argument
of the Execute Process Task like “/script=C:\Temp\sftploader.txt” (without quotes).

Unable to execute a command line command using Java

I am trying to run a command to add a group name. It is executed in command prompt of Windows 2003/2000
Say this is the command I want to execute:
net localgroup LordSM /add
Here LordSM is the group name.
I wrote the following code but it does not seem to work. Please suggest.
String ABC=Value1TextField.getText();
Value2Label.setText("Value is now " + ABC);
// Above is to get value from a JText Field
// Below is the code to run command for adding a group name to a System.
String ExecutedCmd = "net localgroup " + ABC + "/add";
Process p = Runtime.getRuntime().exec(ExecutedCmd);
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("Here is the standard output of the command:\n");
while ((s = stdInput.readLine()) != null)
{ System.out.println(s); }
// read any errors from the attempted command
System.out.println("Here is the standard error of the command (if any):\n");
while ((s = stdError.readLine()) != null)
{ System.out.println(s); }

while ((s = stdError.readLine()) != null)
{ System.out.println(s); }
It does not seem to work means, that no Standard Error is defined, when it executes and group name is not added as well. The following is JUnit Test Result: Hope it gives a better idea of the problem I am facing:
compile:
run:
Here is the standard output of the command:
Here is the standard error of the command (if any):
The syntax of this command is:
NET LOCALGROUP [groupname [/COMMENT:"text"]] [DOMAIN]
groupname {ADD [/COMMENT:"text"] | /DELETE} [DOMAIN]
groupname name [...] {ADD | /DELETE} [DOMAIN]
Got it
BUILD SUCCESSFUL (total time: 10 minutes 49 seconds)
I had even tried this:
Runtime rt =Runtime.getRuntime();
String[] cmd = new String[3];
cmd[0] = "cmd.exe";
cmd[1]="net localgroup";
cmd[2] =ABC + "/add";
rt.exec(cmd);
but again, it does not give any error as such, but it does not create the group name either. Please suggest. We can see the group names that are added on right clicking My Computer Icon and click Manage and then go to User & Group section. On executing either of the code nothing happens.
Thanks

How to execute sqlplus command in bat file ?

Hello
I have a simple script file that looks like this:
"sqlplus admin/admin as sysdba
shutdown immediate"
But.. when i start this file.bat my system logs but do not make any script. Sqlplus just waiting for command, and when i write "exit" i logout from sqlplus, and then system execute next command, that is "shutdown immediate" but beyond sqlplus (so my base is still working). Is it at all possible to log on and execute commands from file.bat or some other way ?
I'm using oracle 11g, windows 7x64
Regards and thx for help

Thank you that worked for me.But I fear you don't really understand WHY it worked, and WHY your first attempts did not work.
So let me explain
Given this .bat file
sqlplus / as sysdba
shutdown immediateWhat happens when you execute the file? The windows command processor reads the file line by line and processes the command on each line. What is the first lilne?
sqlplus / as sysdbaSo what would you expect to happen when Windows processes that line? Remember, it's exactly as if you had entered that command yourself at the command prompt .... Answer: The OS locates an executable file named 'sqlplus', loads it into memory and passes control to it, along with a pointer to the rest of the command line ('/ as sysdba'). At that point, the executable sqlplus has control and will do whatever it wants with the command line it was passed ('/ as sysdba') and then waits for user input for more commands, including an 'exit' command. Where are those commands going to come from? They are NOT going to come from the next line in the bat file. They can't. The command processor that is running the bat file is still waiting for sqlplus to finish and return control. So you are stuck. The only way out is to break out of sqlplus with a 'ctl-break'. Once that happens, the command processor moves on to the next line in the bat file:
shutdown immediateSo now the os tries to locate an executable file named 'shutdown' .... you probably don't have an executable by that name (let's hope not!) so you then get an error message from the OS informing you that
'shutdown' is not recognized as an internal or external command,
operable program or batch file.Now, if you were using a real OS, you could achieve what you wanted by using input redirection, but unfortunately, Windows just has a toy for a command processor.

Trying to find a way to execute from command prompt using java....

I want to find a way to execute a command from the command line using a java program this is my code:
import java.io.*;
public class SQLHopefully
     public static void main(String[] args)
          try{
          Runtime rt = Runtime.getRuntime();
          Process proc = rt.exec("cmd /k start cmd.exe");
          OutputStream out = proc.getOutputStream();
          System.out.println(out);
          out.write("test.txt".getBytes()); //I THOUGHT THIS WOULD WORK
          InputStream stdin = proc.getErrorStream();
          InputStreamReader isr = new InputStreamReader(stdin);
          BufferedReader br = new BufferedReader(isr);
          String line = null;
          while ( (line = br.readLine()) != null) {
          System.out.println(line);
          stdin = proc.getInputStream();
          isr = new InputStreamReader(stdin);
          br = new BufferedReader(isr);
          line = null;
          while ( (line = br.readLine()) != null) {
          System.out.println(line);
          int exitVal;
          try {
          exitVal = proc.waitFor();
          } catch (InterruptedException e) {
          throw new IOException(e.getMessage());
          if (exitVal != 0) {
          throw new IOException("Exit value was " + exitVal ");
          }catch(IOException e)
          {System.out.println("ummmmm");}
I hope my code is readable. I am trying to get the command prompt that comes up from the Runtime.exec() to run a file called "test.txt" I know it would be easier to just do it by executing it from java but I want to see if it is possible this way. I thought the out.write would do the trick but I was wrong. Somebody help please....

First read this article:
http://www.javaworld.com/javaworld/jw-12-2000/jw-1229-traps.html
Second, you should probably send the Enter key to the shell if you want anything to happen. (Not that I know whether it will work, but I do know it won't work if you don't press Enter.)
