Run os system command

Hello at all.
I need an information.
Exist a package that permit the execution of os system command into protect environment like UTL_FILE package that limit the action to the paths specified into utl_file_dir parameter ?
Thanks
Alessandro

UTL_FILE_DIR is no longer the preferred usage.
At the database level, the utl_file read/write path is better specified using a name of a Database Directory (created using CREATE DIRECTORY command) instead of the older ULT_FILE_DIR. This way, only oracle users granted the read/write permission to the database directory can use it.
At the OS level, ensure that only required OS users have permission to read/write to the path. Normally. any files you create with utl_file will be automatically owned by the oracle software owner (usually oracle) because is is created by the oracle shadow process.

  • Run operating system command for sender File adpter (NFS)

    Hi All,
    iam doing a file to RFC scenario, using 'Run operating system command' in sender file adapter to change the file name while archiving (after processing completed).
    I mention OS command like this:
    sample_server\scripts\Test\Rename.bat"
    Rename.bat file calls a 'perl script' code.
    when i run interface, could see below statement in adapter log ->
    "Execute OS command "
    sample_server\scripts\Test\Rename.bat"
    but the script was not run and file name was not changed.
    Please advice what could be the problem?
    Does this mean script executed successfully?
    Do i need install perl software on XI server, even perl script (.bat file) is executing on sample_server?
    Thanks in advance..

  • RUN OPERATING SYSTEM COMMAND BEFORE MESSAGE PROCESSING

    hi.
    just i want to know what is the purpose of run operating system command before message processing,after message processing under file sender adapter.
    waiting for your great answer.
    bye.
    regards.
    seeta ram.

    Hello Seeta,
    let me see if I give it using a simple scenario that I implamented : i nedd to transfer a very large file from one server to the other by XI.
    to save space and network traffic I use an OS command before picking up the file to run a zip command to zip the file.
    after I transfer the file to the target server I run another OS command after the transfer to unzip the file.
    now to your second question:
    the before Os command on the target server is used mostly for checks (make sure there isn't a file by that name or backing up existing data)
    and the after sender OS command is usualy for backing up or erasing existing files (cause it is done only after the first part was finished succesfully).

  • Run Operating System Commands

    Hi,
    There is an urgent requirement, i want to know about Run Operating System Commands in file adapter. What are all possible commands for windows operating system? and how it works? Kindly send me your suggestions and links at the earliest.
    Your help will be appreciated.
    Thanks,
    Sadhna.

    Hi,
    Run Operating System Command Before/After Message Processing
    ●      Command Line
    An operating system command specified here is executed before or after the message processing of a file that was found in a run. The default value is an empty character string (no command).
    When the operating system command is called, the file name currently being processed can be specified with the following placeholders:
    ●        %f (file name)
    ●        %F(absolute file name including path)
    ●      Timeout (secs)
    This specifies the maximum runtime of the executing program in seconds. When this time interval is exceeded, the adapter continues processing. The executing program continues to run in the background.
    ●      Terminate Program After Timeout
    Set this indicator if the adapter is to terminate the executing program when the timeout is exceeded.
    The adapter writes the output (STDOUT and STDERR) for the operating system command in the system trace.

  • How to Run Operating System Command Before/After Message Processing SAP PI

    Hi,
    We are trying to execute multiple commands via "Operating System Command Before/After Message Processing".
    When we use single command say for example cp or mv (copy or move) the commands get executed fine.
    eg: cp %F /var/opt/data/outbound/Test/Dummy.txt 
    /this works fine/
    when we club commands together or try to redirect the outputs of commands, none of the commands get executed.
    eg:
    cp %F /var/opt/data/outbound/Test/Dummy.txt ; rm %F
    or
    wc -l %F > /var/opt/data/outbound/Test/Dummy.txt
    Is it possible to execute multiple commands or redirect the output  of commands without using a shell script? The PI server we are working on iis hosted on UNIX environment.

    Hi Harleen,
    try like this
    cp %F /var/opt/data/outbound/Test/Dummy.txt ; rm %F
    instead of semicolon try this
    (1) &
    command1 & command2
    Execute Command1 and then execute Command2
    (2) &&
    command1 && command2
    Runs the command2 only when command1 doesn't Complete successfully
    (3) ||
    command1 || command2
    Runs the second command if the first command had an error
    (4) ()
    (command1 || command2) || (command3 & command4)
    Defines the order in which commands are to be executed

  • Run 2 systems command in applet, how?

    I have an applet in which the following code works fine on a windows machine for a VM windows-based router I am developing:
    Process f;
    String cmd="tftp -i 192.168.1.101 GET router_image.exe";
    try{
         f=Runtime.getRuntime().exec(cmd);
    }But I also need to add a 5 second pause and then run the router_image.exe.
    Using the above commands (or modifications thereto), is this possible? If so, what would need to be done.
    Thanks.

  • Regarding Run operating system command

    Hi experts,
    I have a requirement of creating an empty file onto the same folder where my reciever file adapter writes the result file. Is it possible in case of FTP as well or is just supported for NFS?
    Regards,
    Amol

    Hi Amol,
    I have no experience with scripts. But if my understanding is correct, you can achieve this. The script file to be called should be placed in your XI server. The script file will have commands to do the FTP and create file in the remote FTP server. Although I have never worked on scripts to be 100% sure. May be a person familar with scripts can give the cirrect info.

    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();

  • Problem with zip operating system command

    Hello,
    i have the following configuration in the file receiver adapter:
    Directory: /tmp/
    File Name Scheme: %name%.txt
    Variable substitution:
    Variable Name: name                 Reference: payload: record,1,name,1
    Run Operating system command:
    /usr/bin/zip /tmp/%f.zip %F
    The execution is succesful, but i have a small problem. The file name is "file.txt.zip", the .txt should appear but i dont know how to skip it, I have tried so many ways but it doesnt work, I should receive a file called "file.zip" With a file inside in txt format...
    Thanks,
    Luis

    Hi Sriram,
    Thanks, but that wouldnt work out, Im using the %f for my file name, so this move command shouldnt work for me, because my filename changes in every execution, so I cant write something like this: mv file.txt.zip file.zip
    The only solution I see would would be a command which deals with strings and that could remove the four last characters of "%f"..but I havent found anything for doing it.
    Regards,
