That is NOT for Oracle-on-Linux questions. It is a forum for questions specific to that distro of Linux.
You have a Python question.
The post has been relocated to the Database General forum.
@ O.P.:
Maybe this will help. It was the first result from Google when searching on keywords `oracle python`:

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) {...

Hi SH,
I tried running the scenario from the command line, but the process was not completed and it came back with the below message

Do I need to set up any environmental variables or any other setups before I can run the scenario from the command line?

You might improve your chances of getting help if you do two things:
1) Explain what "not working" means.
2) ChangeSystem.out.println(IOEx); to IOEx.printStackTrace(); (in the eventhat is in fact related to "not working").

How to show a Image (from shell, python or what ever)

Hi guys
An Application written in c#/mono takes up to 7 seconds to start. So i was asked to do a little splash screen for it.
I coul'd not figure out how to do it from shell and i couldn't find the pygtk bindings installed, so i did it quick and dirty in mono showing just an animated gif and killing the process after the applicaiton started.
The problem with this Solution is that the splash screen itself takes up to 3 seconds to show up, which is quite long.
Any idea how i could do it from shell or maybe in python or c? Thing is, i can't install any new libraries on that system so it has to be done with the very basic stuff that comes with the xserver.
Window manager is fvwm. And i would like to stick with the animated gif, since i already have it.
Lg, Archdove
display (imagemagic) is probably installed. But how can i deactivate the window decorator? It would also help if i could just set the window title by my self since there is a rule (which i cannot alter or add one more) to do this for special windows.
Last edited by Archdove (2012-01-25 19:05:38)

Got it with the -title switch... don't know if it will help me tough
I just keep updateing here... the tool animate has to be used to animate the gif.
So what i still need to know is how i can set the exact position of the window to be shown.
animate -geometry 100%+0+300 -delay 10 -title windowTitle loading14.gif - BÄM!

Refer to the Example User Interfaces section in Chapter 9, Creating Custom User Interfaces, of the TestStand Reference Manual (p. 9-1):
Example User Interfaces
The <TestStand>\UserInterfaces directory includes the executable, project, and source code files for each example user interface. The Full-Featured subdirectory contains user interfaces for loading, viewing, editing, saving, executing, and debugging sequence files. The Simple subdirectory contains similar but limited user interfaces with fewer commands and options but no menus. Also, the simple example user interfaces display the steps for executions you run but do not display steps for sequences you load. Both subdirectories contain source code for LabVIEW, LabWindows/CVI, Microsoft Visual Basic .NET, C#, and C++ (MFC).TestStand installs the source code files for the default user interfaces in the <TestStand>\UserInterfaces and <TestStand Public>\UserInterfaces directories. To modify the installed user interfaces or to create new user interfaces, modify the files in the <TestStand Public>\UserInterfaces directory. You can use the read-only source files for the default user interfaces in the <TestStand>\ UserInterfaces directory as a reference. When you modify installed files, rename the files after you modify them if you want to create a separate custom component. You do not have to rename the files after you modify them if you only want to modify the behavior of an existing component. If you do not rename the files and you use the files in a future version of TestStand, changes National Instruments makes to the component might not be compatible with the modified version of the component. Storing new and customized files in the <TestStand Public> directory ensures that new installations of the same version of TestStand do not overwrite the customizations and ensures that uninstalling TestStand does not remove the files you customize.
Note: National Instruments recommends that you track the changes you make to the user interface source code files so you can integrate the changes with any enhancements in future versions of the TestStand User Interfaces.
You might also find the Example Programs topic in the NI TestStand Help useful for other tasks.

How to execute the query from different blocks in Forms

Hi,
Curently I have a case where I need to execute the query from some other block. I used
l_curr_item VARCHAR2(62) := :SYSTEM.CURSOR_ITEM;
Go_Block ('BLOCK2');
Execute_Query;
Go_Item(l_curr_item);
This works fine , but as I am using Go_Block it does some other activities related to that block, which I dont want them to get executed.
So can any one please suggest me how I can call the query alone without using the Go_Block .
Thank you.

you can set global variable and filter for this variable in the triggers of blocks the actions then you avoid the code of trigger and you can use go_block
