Is it possible to execute a process from BI?

I am implementing in BI a web app which currently relies on calling a local program to get some of its report information. I know BI wants everything to be in a DB, so I'm wondering how to imitate this functionality. I can think of a few hacks (e.g., decorate a BI report w/ JavaScript which calls out via ajax to a server which executes the process) but would like to know if there is some simple supported way to do this.
thanks.

On your first question: no, you cannot start a script from (server side) PL/SQL - you can only do so from client PL/SQL in Oracle Forms.
What you can so is:
- create a stored java procedure that does what you need, wrap it in a PL/SQL wrapper and invoke it from your PL/SQL code
- use UTL_FILE to write a file on the file-system that subsequently can be picked by some polling background process that will trigger execution of the script mentioned in the file you just wrote; note however that this is not only quite awkward, it also means that the script execution happens in a different thread from your PL/SQL code and no direct communication between the two exists. BTW You can also use a database pipe to send out a message to a background process outside of the database to request execution of a script. The same caveats still apply.
There may be other tricks for this challenge. Good luck, anyway.

Oh, bummer. Would be much more convenient if I could just use iTunes for everything. Can't stand WMP. I wonder if WinAmp might be a good compromise?

Need to invoke a process from a column link and then redirect to a url

Is it possible to invoke a process from a column link then redirect to a url
I want to invoke a process that has a pl sql block of code which will do some table inserts and then redirect the user to an external url.
Any help would be appreciated.

Howdy Scott,
I thought this might help me but I've got a dynamic form with apex_application.g_f01(i) items on it ie tabular form. How can I take the value of these arrays with me to the temporary page with the onload process?

Is it possible to call an Applescript from a jsx

I can find lots of discussion around calling a jsx script from applescript - but nothing about the other way round. Is it possible to execute an applescript from a .jsx script?

Yes, there are a few ways of doing it, please see...

Is it possible to run a report from another machine?

Lets say you design a report on machine A that contains the CR Developer Software Package.
Is it possible to execute the report from machine B that does not contain CR Developer Package?
Is there tool or a command that you can run that will execute the report created in machine A?
Thanks in advance,
Zack H.

Crystal Enterprise (or BOE) will run a report developed on machine A and imported to a repository on the CE/BOE machine. Is that what you mean? Or, I suppose anything that can run a Crystal Report given the file name could run it if the UNC path is given for the file name (assuming database connections are set up on the running machine)...

Start process from JSP which continues running after response is completed

Is it possible to start a process from within JSP which can continue running after the HTTP response is complete, so the response doesn't time out??

Your question is a little vague. If I am understanding your question correctly, it sounds like you are starting a process in JSP that takes a long time, and the browser is timing out. If this is your question, then here is my response:
We've had this situation before. Often times it occurs because the JSP page launches a long database operation that could take an hour. You have a few choices, but one good approach is this (any variation of this works too):
1. When the page loads and you need the process to start, create a new thread and have the long operation run from this thread. You can put the thread object into a session variable and store it for later use.
2. Have the JSP code output a META-REFRESH tag on the page so that the page refreshes every 30 seconds or so.
3. On each refresh, you get the thread object from the session context and check it to see if it is done or still running. If it is, then just output another META-REFRESH and the page will keep refreshing itself. If it is done, you can, of course, output a "finished" message to the user.
You can also have a stop button on the page that you can use to send a message to the thread to stop.
Hope that gives you some ideas!

Is it possible to excute DB2 function from ODI

Is it possible to execute DB2 function from ODI.
If it is could you please help me how to proceed
Thanks

if it is a function which is used in SQL, then you just use it in the mapping, as you would normally.
If it is a stored procedure, then you may need to execute it in a procedure.

Killing an exec'ed process from another thread

Hi all,
I written an application that executes some external OS - processes. There is a dispatcher thread, that starts the execution threads for some jobs. Every execution thread creates a Processes by calling runtime.exec(), adds this object to a TreeMap ( member of the dispatcher ), creates two threads for reading the output of the process ( sdtout & stderr ) and calls p.waitFor(). From this moment this thread is blocked. After the process is done, the results will be processed by this thread etc. Now I want to go ahead and let the application user kill the process. For them I let the dispatcher - thread, that has also a reference to the executed process to call destroy of it if necessary during the execution thread is blocked by waitFor() and two output threads are reading stdout & stderr. The problem is however that destroy() - call from another thread doesn't kill the subprocess. The subprocess is running until it's done or terminated from out of jvm. Have you an idea or example?
Thanks a lot & regards
Alex

>
I know you have been discussing your problem is that
you can't kill a "sleep" process. But just to be
sure, I tested your description by one thread exec-ing
a "not-sleep" program, and then another thread had no
trouble killing it.
I took your code and wrote a program around it such
that
Thread1 :
- creates a Job (but not a "sleep" job); creates a
JobMap ; puts Job in JobMap
- starts Thread2 (passing it JobMap)
- sleeps 15 seconds
- calls Job.kill() (your method)
Thread2 :
- gets Job from JobMap
- calls Job.execute() (your method)
It's quick and dirty and sloppy, but it works. The
result is when the kill takes place, the execute
method (Thread2) wakes from its waitFor, and gets
exitValue() = 1 for the Process.
so,
In order to kill the sleep process, which (according
to BIJ) is not the Process that you have from exec
call, maybe the only way to kill it is to get its PID
an exec a "kill -9" on it, same as you said you had to
do from the commandline. I don't know if you can get
the PID, maybe you can get the exec-ed process to spit
it onto stdout or stderr?
(I am on win, not *nix, right now, so I am just
throwing out a suggestion before bowing out of this
discussion.)
/MelHi Mel,
yes, it should work right on windows because you created probably the shell by cmd /c or something like this. If you kill the cmd - process, everithing executed by the interpretter will be killed too. My application is running on Windows and unix. On unix I have to execute the process from a shell ( in my case it is the born shell ). The problem is however, that the born shell has another behaviour as cmd and doesn't die. Do you have an idea how to get the pid of the process started by sh without command line? To kill the processes from the command line is exactly what my customers do now. But they want to get "a better service" ...:-)

Is it possible to extract a VI from an executable which has debug mode enabled?

It is a curiosity question from a client.
Is it possible to extract a VI from an executable which has debug mode enabled?
Since the block diagram would not be in edit mode.... Is it possible to "peer" into the executable, look at a VI and recover the block diagram? This owuld be for a deleted VI that is part of an executable which had debug mode enabled..
Did anyone try this?
Curious..

Extract VIs from an EXE? No problem. Even if debugging isn't enabled you can extract VIs, they just won't have block diagrams, and may not have front panels depending on if they were removed in the EXE making process.
Attached is an example project for making an EXE, the EXE itself, and a VI for extracting VIs from the EXE. The code is quite primative and it was just meant to demonstrate how this can be done.
To extract the Main.vi from the Application.exe, run Extract Main.vi from EXE.vi, provide the path to the EXE and the path to where the VI should be saved and then run the VI. This VI will set keys in the INI file for the application, then run th EXE. Then it opens an application reference to the EXE, then opens a VI reference to Main.vi. Then it aborts Main.vi, and extracts it.

Is it possible to execute a stored procedure from application express?

I have created a pl/sql application now I would like to give it a front end, I am new to application express.
My application depends on running a couple of pl/sql procedures that modify data.
What I need is my user to be able to execute the procedures from the application in a browser, is it possible to run a pl/sql procedure from an application express application in a browser?
how would I go about doing this?
thank you very much.
Ramiro

You sure can.
If you want to run a PL/SQL procedure/package/function from the URL, create a specific DAD entry just for that (Oracle) user, and give that user EXECUTE permissions on the procedure. Then just use the new DAD with the procedure name, like http://myserver.somewhere.com/MyNewDAD/Schema_Owner.MyPackage.MyProcedure?InParameter=MyParameter)
Of course, the above line will need heavy modification on your end, but I do this in my app, but I actaully pass it through a javascript attached to a button which then opens it in a new window.
If instead, all you want to do is execute a procedure with ApEx as part of a validation or process or something, select the PL/SQL 'Region' (or process, whatever it is you want to do), and then write it as an anonymous block:
begin
MyProcedure;
end;

OWB PRO out there : is it possible SQL to execute OMB*PLUS from Database ?

Hi,
With 11g out : is there any expert who sucessfully integrate pl/sql routine to call OMB. Here's the point : You have an APEX application and you design your stuff and at one point you wish you just have to press a button and generate a first draft of your design in the OWB repository, and then developpers can have a frame to start designing from your perspective.
Also, imagine you have an APEX form to approve the testing of a design or process flow or both, and when you press the i approve button, you get call an OMB*Plus routine that do all the export->import reconcile and deploy thing!
I don't think i'm alone to need this kind of stuff. So since OWB is Java, and Oracle database speek Java : is it possible to think of a quick solution ?
Thank you all.

Hi bpaquet,
As you know OMB+ is TCL extension, and as i know OMB is not integrated into RDBMS.
I think, there can be several solutions.
1. Execute shell scripts from db using dbms_pipe package.
2. Execute shell scripts using some java external procedure.
3. Create some OS scheduled job (crontab), which will check some values in DB and execute OMB scripts.

Execute SSIS Package from JOB which contains Execute Process Task calling a .bat file

Hi All,
I have a EXCEL Macro needs to be called from SSIS. We could not use Script task because of some internal reason.
So we have taken an approach to call a .BAT file using Execute Process Task. This .BAT file will call a .VBS file which will execute the EXCEL Macro.
The SSIS Package is running good if I execute the package from BIDS.
But the real problem is with the scheduling this SSIS Package using SQL JOB.
If i execute this SSIS package from SQL Server Job, its executing the whole package successfully except the Execute Process Task.
So the overall issue is SQL Server Job is not executing properly if I call any .BAT file from the SSIS Package.
Please give me suggestion to get rid of the issue. Thanks in advance.

Hi Sai.N,
If you run the SQL Server Agent job manually from SSMS, does the package execute properly? If the package executes properly when you run the job manually, the issue should occur due to permission issue. In this case, I suggest that you create a SQL Server
Agent proxy based on the current Windows account which you use to log onto the operating system, and run the job under the proxy account.
If it is not the issue, please enable logging in the package as Visakh mentioned and post the warning/error message for further analysis.

Is it possible to trigger a bpel process from a database object.

Hi,
We want to schedule a bpel process to run daily .So we want to trigger it from a database job.
Is it possible to call a bpel process from database..?
Or
Is there any way to schedule a bpel process from bpel server it self.
Thank you
Gayaz

If you know about DBMS_JOBs then I would say the easiest way to invoke a BPEL process is via the AQ adapter. You just need to populate an AQ and a way you go. The good thing about this is that if SOA SUite is down when the schedule is run you don't need to retry, it will be picked up when it comes online again.
cheers
