Issuing commands from a Linux box

I need to let a Linux box send simple commands to a Windows Server host.
I am considering PowerShell Web Access but it looks complex, while the commands I need to send are quite simple (1-5 command lines).
What is the simplest way to allow a Linux box send commands to a Windows Server?
Consider that both the Linux box and the Windows Server are in the same LAN, so security is an issue but access from the web is not required.

Mario

There are several Powershell web server and REST Web server projects on github:

What do I need to open a connection from the Linux box to the Oracle server

Hi all,
I want to access oracle database from java application running on Linux.
The database is installed on a Window 2000 machine. What do I need to install before I can open a connection from the Linux box to the Oracle server on Windows 2000 ?
Do I need Oracle Client ?
Thanks,
Quoi

What is the webconference tool of choice for demos from a linux box?

Since conference.oracle.com and strtc only work on IE, what are folks doing when they want to do a webconference from a linux box? Are people installing IE (I see it is possible but sounds a bit hacky), or is there another oracle conference tool or are people connecting from a PC to the linux box and running conference from there (is that possible?).
Thanks for any idea you could give me.

Uable to read imagfile with speacial character in its NAME;from a linux box

Hi, i am facing a problem in reading a image file( file name having special character {G�stehaus}) from Linux file system.[FileNotFoundException]
I compiled my code in windows machine and run the same in Linux box.
The same file, i am able to read from a windows file system.
I think there is no problem with Linux box encoding/decoding as the file name displaying as-is.
I am expecting the problem in encoding/decoding between Java and Linux box.
Help me in solving this issue.

Hi Corlettk, thanks for your immediate reply.The actual problem is with special characters [some Greek and Spanish accent characters ].
Please find some file names example below:

Command to find Linux box - RAM utilisation

Is there a command to find the total memory utilised by all the processes in the Linux server?
Unix Command to check RAM used by one Oracle instance.
- BMP

Unix command such as ps may add the shared memory segment size used by the SGA to each dedicated server process.
$ ipcs -mob will give all size of shared memory segments and this includes all SGA size for each instance running on your box.
To get PGA, you will need to use a SQL statement:
select * from v$pgastat;

Unable to connect to SQL Server 2008 from OBIEE 11G(on 64 bit Linux box)

We are unable to connect to connect to SQL Server 2008 from OBIEE 11G which is on 64 bit Red Hat Enterprise Linux.
Infrastructure: OBIEE 11.1.1.5 64bit, on 64 bit Red Hat Linux Enterprise Linux 5.6 , MS SQL Server 2008 on 64 bit Microsoft Windows Server
Issue Description: Unable to connect to SQL Server 2008 from OBIEE11G RPD
Details: We are unable to connect to SQL Server 2008 from OBIEE which is on a 64 bit Linux box. We created the ODBC connection on Linux box to the SQL server. Whenever we try to import metadata it throws an error that says ‘Connection Failed’.
Here are the steps we followed to setup the ODBC connection on Linux box.
1) We updated the user.sh file with the LD_LIBRARY_PATH and LD_LIBRARY_PATH_64 values that point to $ORACLE_HOME/bifoundation/odbc/lib
This is where we found the driver for SQL server SEmsss23.so.
2) We updated the odbc.ini file with the entry for SQL server with the connection details
SI_SQL_Server_DEV = SQL Server
[SI_SQL_Server_DEV]
Driver=/u001_OAS/Oracle/Middleware/Oracle_BI1/bifoundation/odbc/lib/SEmsss23.so

ConnectionRetryDelay=3
Database=SVBDW_NEW
LoadBalancing=0
LogonID=SIDatavalidation
Password=~~~Password123

ReportCodePageConversionErrors=0
3) We updated the IDENTIFIER_QUOTE_CHAR with single quotes instead of double quotes in the DB features of the RPD
4) We updated the bash_profile file to point the ODBCINI variable to the path where the OBIEE odbc.ini file is present.
Export ODBCINI=/u001_OAS/Oracle/Middleware/instances/instance1/bifoundation/OracleBIApplication/coreapplication/setup/odbc.ini
The error in nqsserver.log file says “[nQSError: 16001] ODBC error state: IM002 code: 0 message: [DataDirect][ODBC lib] Data source name not found and no default driver specified.”

Hi,
Make sure SQL Configuration Manager make sure the TCP/IP enabled. please try below method
Method 1
Re Create a new ODBC & Oracle Bi Server DSN Configuration test it and use it in the connection pools.
define your ODBC data source in your server where the BI Server is installed. Check your DB connections in your physical layer and make they are defined on your BI Server as well.
Method 2:
try using the complete TNS in below format in the datasource name section:
(DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP) (HOST =DB IP)(PORT = 1521)) ) (CONNECT_DATA = (SERVICE_NAME = ORCL) ) and provide the credentials.
Method 3:
To use the OCI call interface you need to have oracle client DB to be installed so that you can establish a connection using that DB credentials and connect to the remote dB and then import the tables.....this is the rule of thumb.
hope helps you.
Thanks

Sending down Linux commands from database

Hello
Im working with Oracle 10.2.0.4.3 on Linux SuSE FUSE Version 2.3.0-RC0-SL0/SLES-9.
Im currently doing an extract of BLOB files down to a directory on the server.
When I do the extract the Oracle user becomes the owner of the files and my own user doesn't have the access (neither read or write) to the files.
I cannot receive Oracle access due a security issue so Im wondering if its possible to send down a command from the database that does a
$chmod a+rw my_directory/*.* ?
Iv looked into the some forums and I didnt find anything in particulate that would help me, so Im wondering if any of you know if this is possible ?
BR / SA

Hello
Thank you for your advice but the question was to send down Linux commands from the DB, not do anything in the Linux enviroment.
Here is a good place to start that I found on the net.
public class JShellCommand {
public static int execute(String cmd) {
try
String[] shellCmd = { "/bin/sh", "-c", cmd };
Process process = Runtime.getRuntime().exec(shellCmd);
int exitVal = process.waitFor();
return (exitVal);
catch (Exception e)
return 1;
load it into db with loadjava and wrap it with:
CREATE OR REPLACE
FUNCTION Shell_Command(
p_CMD IN VARCHAR2
RETURN NUMBER
AS
LANGUAGE JAVA
NAME 'JShellCommand.execute(java.lang.String) return int';
For OS command you can use:
public class JCommand {
public static int execute(String cmd) {
try
Process process = Runtime.getRuntime().exec(cmd);
int exitVal = process.waitFor();
return (exitVal);
catch (Exception e)
return 1;
and
CREATE OR REPLACE
FUNCTION OS_Command(
p_Cmd IN VARCHAR2
RETURN NUMBER
AS LANGUAGE JAVA
NAME 'JCommand.execute(java.lang.String) return int';

I am using the Iplanet Webserver 6.0 on a Linux 7.2 platform. Like I
said, sqlplus works fine, standard java application works fine but
when I change it to a servlet (which means it now goes through the
webserver, I get this error message)
Does anyone know what the source code is trying to do at
OCIDBAccess.java:1743 ?
Thanks guys!

Tony, could you please explain me better the procedure that you wrote?
What are the boxes? My situation is similar:
| ServerSocket (1) |
| (192.168.1.100, 5555) |
|
|
|
|
| Proxy |
| Someone wants to connect to the ServerSocket (1) |
That is not true. You CAN do it but you need a box
outside the firewall with proper IP address to help
you. I am not sure if Sergio still wants the answer
today after more than a year from the original post (I
did not see the post until today when I try to search
for something else). Anyway, if such a box is
available (I call it 2nd box), you could first
establish a socket between the two boxes by HTTP
tunneling (I assume it is a http proxy). You have to
initiate the socket from the 1st box. Then start
another server socket on the 2nd box, forwarding the
traffic it gets from outside back to the 1st box using
the established channel. That is it.

Print command from linux PC on to Windows Environment

Hi Experts,
We have SAP on Windows and the network printer is also on Windows, the PC with Linux is integrated with network printer i.e when the print command from Linux is given the output is available from the printer (Windows). But when the print command is given through SAP there is no output from Printer (Windows).
When same user logs into Windows the printer command is successful.

hi hari,
Printing SAP documents using Linux client is a little bit tricky if you want to get good printing result just as when you print from your Windows client.
If you want to use G printing method (on Linux client), you can't use SAPWIN on device type since SAPWIN is relying printing method. You must use exact printer driver. For example when you're using Dot Matrix printer Epson LX300+, you can use EPESCP2
I am using different method to cheat this and it's completely work.

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) {...

               e.printStackTrace();
}Help please.

Your code is probably good to run a program, that does not use terminal capabilities.
Program "top" is a little bit more complicated - you have to run it with a real terminal.
Try to run "xterm -e top". You can find an example how to run an external program
from java code in cnd/gdb module on http://cnd.netbeans.org
For example, take a look at openExternalProgramIOWindow() method on this page:
http://cnd.netbeans.org/source/browse/cnd/gdb/src/org/netbeans/modules/cnd/debugger/gdb/proxy/Attic/GdbProxyCL.java?rev=1.1.2.6.2.5&only_with_tag=release551_fixes&view=markup
It runs a command with external terminal.

How to execute linux sh command from inside CF

I am using CFMX 7,0,0,91690 Enterprise on Redhat Enterprise Linux 4.9 with Apache webserver 2.0.52. I have a coldfusion template that queries from a Postgresql 8.0 database, copies the data from the queries into a set of files in one folder on the linux server, and then has a CFEXECUTE tag at the very end that calls a bash shell script on the same server. The shell script takes the files from the one folder, merges some of their content together, moves them to another folder, adds header and footer, and sets ownership and permissions. These 2 scripts have been in place and working perfectly for several years now. No changes were made to content, permissions, or ownershop of scripts. Suddenly last Friday the coldfusion script seems to have lost its ability to execute the shell script properly. It does execute it and the shell script attempts to do some of the steps, but the resulting files are missing the content and have the linux environmental variables and their values displayed instead. Clearly its getting an error but that is not being reported back to me. After the CF script ends, if I manually execute the shell script from the linux command line, it works perfectly. I tried giving it more permissions but that did not help. Redhat support suggests I run the script with "sh -x" to get more detailed output for debugging, but I would need to do that from inside the CF script since that is where the problem is. Is it possible to execute a shell script from inside a CF script using a linux "sh" command in some way (instead of the cfexecute, just so I can see debugging info)? Thanks in advance for any suggestions. Julie

Thanks for the suggestion, tried that too:
<cfexecute name="/bin/sh" arguments="-x /bin/siscopy" outputfile="/home/coldfusion/sh_output.txt" timeout="600" />
still didn't work. Script ends with this coldfusion error: Timeout period expired without completion of /bin/sh
It does not complete the task of making the files, and the sh_output.txt file which is supposed to capture the -x output, is empty.
Thanks,
Julie
