Xcelsius runs only once, then the "play=true" needs to be reset.
Post Author: stephantmi
CA Forum: Xcelsius and Live Office
When I export into PowerPoint the dashboard will only run one time... I then need to goto properties and find "play" and change from "false" to "true". I found a website that stated "Note: we've recently discovered that if the flash movie is scripted to stop
playing rather than loop or repeat then this command appears to be passed to
PowerPoint - this results in the play command being reset to false. The simple
solution (if you've got the source flash file) is to remove the offending command,
alternatively you'll have to save the presentation with play set to true and
not run it again until ready to present - it'll only run once and will need
resetting before it'll work again!" How do I send out a PowerPoint that would allow the person I would email the presentation to run the slide show and interact with the dashboard if it doesn't initiate without manual intervention.

I assume this is with X2008? BTW. Right-clicking on the flash and choosing 'play' should also work. This is an Adobe issue. They have increased the security on the use of flash files. They are afraid of malicious use and viruses so they now require manual intervention. You could contact Adobe and let them know how this security feature is affecting you. Xcelsius is also currently in talks with them. - Andy

Hi All,
I am trying to execute the below code as provided from one of the blogs. i am able to run the job only once based on a file watcher object(i.e. for very first time) and after that the job is not running at all and if i schedule the job to run automatically based on interval of 10 or more minutes it is executing properly). Please let me know or guide me if i have missed any step or configuration.that is needed.

How do I submit a job to run only once?
I have a stored procedure that submits a job. If this job fails, I don't want it to continue trying to run. Does anyone know how to ensure that it will only run once, no matter what?
I did try something similar to the following:
procedure proc_submitted_as_job(p_job_no number) is
begin
dbms_job.broken(p_job_no, true);
end;
However, I found out that if you change the Broken state while a job is running, then it gets reset when the job completes.
Basically, I'm using the dbms_job utility to run a long-running procedure in the background. If there's another way to obtain this same result, I'd love to hear it.I am still haveing problems so I will try and attach my program and see if you can help a little more that. It will probably be easier for you to look at this way. When you look at the diagram sequence 0 is the one the problem is in. In that sequence you will see a case structure and that is where the finite pulse train vi is. When case 1 is selected the finite pulse train will run again and again until I leave case 1. I need to have the program run the finite pulse train once and then wait and do nothing until the case is changed. The finite pulse train will be in all cases inside the case structure I just haven't done that yet, I am waiting until it works. The pulse train is used to move a stepper motor that is why running only once is im
portant because the stepper motor is used to position something.

Dbms_scheduler - dbms_aq - dbms_aqadm - event driven job runs only once/sec
hi, i tried here to process events with 2 jobs... surprisingly i had to call dbms_lock.sleep(1) to be able to enqueue events
at inserts in a row ... even more surprisingly the enqueuing doesn't function if the processing (prc_evsched) lasts some seconds...
how must the code be changed to be able to enqueue all events after the inserts without any sleep()?
and how must the code be changed to be able to enqueue all events with a proc (prc_evsched) running longer?
thanx in advance for your help!

*/hi, thank you for your (fast) answer! that is the solution to my problem!
now i have a follow-up question:
i've got a procedure, that runs between 1 and 2 minutes long. unlimited running lightweight jobs
would freeze the db...
how can the count of the parallel running lightweight-jobs be limited?
according to the documentation it is not possible:
There is no explicit limit to the number of lightweight jobs that can run simultaneously to process multiple instances of the event.
However, limitations may be imposed by available system resources.
could you explain to me, what it (...available system recources...) means?
eventually what i would like to have: max. two parallel running (lightweight) jobs....
thank you in advance, bye, á
ps: can i attach a file to the post anyway?

How do I get a case to run only once
I am using an e-series DAQ board to bring a pwm signal, then I use labview to use that signal to pick one of three cases. depending on the case picked a finite pulse stream is sent out. Currently the finite pulse vi keeps repeating because the the program stays in the case. I need a way to get labview to run the finite pulse output only once, and not run again until a new case is picked. I don't have the case in a while loop.
Thanks For The HelpI am still haveing problems so I will try and attach my program and see if you can help a little more that. It will probably be easier for you to look at this way. When you look at the diagram sequence 0 is the one the problem is in. In that sequence you will see a case structure and that is where the finite pulse train vi is. When case 1 is selected the finite pulse train will run again and again until I leave case 1. I need to have the program run the finite pulse train once and then wait and do nothing until the case is changed. The finite pulse train will be in all cases inside the case structure I just haven't done that yet, I am waiting until it works. The pulse train is used to move a stepper motor that is why running only once is im
portant because the stepper motor is used to position something.

How to get lauchctl daemons/agents to run only once a day
How do you get a daemons/agents to run only once a day regardless of the error code of the .sh you are running?
(not I'm not looking for run once or run on reboot. I want a job to run at 3am every day and it has several bash commands in it. Regardless of the returns by any of the commands in the script, I only want this to run once - NO RESPAWN).Ok still not working.. here is the plist
the .sh file does file processing and then uploads xml files to my server and should run once a day. Here I have it running at 11:45am. It completes and then runs again and again and again.
The plist is placed in LaunchAgents and loaded with $launchctl load com.iclassicnu.crontabtest.plist

Materialized View to run only once in a year...
Hi everybody...
I want to create a materialized view which will run only once in a year and specifically some minutes after 00:00 a.m. on new year's day,
so i created the following:
CREATE MATERIALIZED VIEW <mv_name>
BUILD IMMEDIATE
REFRESH START WITH TO_DATE('01/01/2007 00:15:00','DD/MM/RRRR HH24:MI:SS')
NEXT SYSDATE+366
I have two notes:
1) how to declare the refresh to be done the first new year's day after the day it'll be created , i mean not static date (01/01/2007)
2)some years are leap and some are not , so in order to run every new year's day how should i transform the above..????
3)is there any view which displays the next run of a materialized view..???
the view DBA_MV_REFRESH_TIMES displays the last refresh of mv's...
I use Oracle 10.2.0.1 on XP ...
Thanks , a lot
Simon1).
use the expression that evaluates to next january first.
SQL> select sysdate, add_months(trunc(sysdate, 'yyyy'), 12) from dual ;
SYSDATE ADD_MONTHS(
19-JUN-2006 01-JAN-2007
1 row selected.
SQL>2). for this also use the same expression that will evaluate to the january first of the year after that. -
when i run keynote in the play mode, some times the computer get stuck, why?, when i run key note in the play mode, some times the computer get stuck, why?
hello,
I had the same issue. This is what I was told to do.
iWork has to be removed completely to be effective when re-installing, you must use an application removal tool to do this or it wont remove every Keynote file.
Appcleaner will do this and its free.
The following procedure has helped solve many issues with Keynote:
1 Close Keynote then use Appcleaner
2 Empty the Trash
3 Shut down the Mac, then restart and press the shift key immediately after the startup sound, then release shift when the Apple logo appears
allow the Mac to boot up to the desktop, it will take longer then usual as the hard drive is being repaired
4 restart the Mac
5 Reinstall iWork
6 Repair permissions:
Applications > Utilities > Disk Utility > First Aid: click on your system disc in the drive column
and select Repair Disk Permissions
7 open Keynote and test -
Executing the webservice only once by the pdf
Hi,
I am using a WebService call in my pdf form but I want to call that webservice only once from the form by that particular user. How can we do that?
I tried to do this by adding the invisible text field in the form and maintain a flag to check the webservice is executed or not. but when I close the pdf and again reopen then the webservice is executed at the first time so how can I solve this problem?
Thanks
NinadSet the Hidden fields Binding property to 'Normal' that way the value in that field is persistent. And then always check for the flag before you execute the code for calling WSDL. Hope this helps.
Good Luck,

What method is called only once in the life cycle?
Hello,
What method is called only once in the life cycle of an Entity Bean and Session Bean?
Is it ejbRemove()?
Thankshi,
ejbCreate() and setSessionContext() are called once by the container after the bean instace is created.when the bean instance goes to pool and again return to ready state to handle client requests these methods r never called .only bussiness methods r called.this is in case of stateless session bean.
in case of stateful session bean, each bean instance is associated with client.so,when new client requests, new bean instance is created and above 2 methods are called. no pool terminology in case of stateful session bean.
ejbRemove() is called by the container when it is abt to remove bean instance,so it its obvious tht it is called only once. -

RegardsHi,
Assuming you have test data like this ;
select 'abc'as [GROUP],'NN' name , 1 id
union all
select 'abc' as [GROUP] ,'PP' name , 1 id
union all
select 'abc'as [GROUP],'RR' name , 2 id
Step1 : take Tablix with row group as your group Name .
Step2 : right Click on Row Group Details -> Delete-> Delete Group Only
Step3 : In Count Cell use below expression ;
=CountDistinct(Fields!id.Value)

Run only once in case structure
Hello,
I have a menu set up that is wired to a case structure. Of course the menu is some boolean buttons that are set to switch when pressed so the case will stay open as long as the button is true.
inside that case I have another menu and a case structure that operates the same. In one of these cases I have a piece of code that I only want to run once. I have tried the while loop that runs once and a for loop that only runs once, but the section of code seems to run continuosly instead of just once. It works ok if I use any of the latch functions but not the switch when pressed functions. However, I need the button to stay pressed until the user is finished with that case.
I really don't want to use an event structure as I was saving that for another piece of code that monitors inputs.
Anyone have a suggestion?Typically, this works easiest with a shift register and and a boolean "implies" function.
In the code example (see image), the button is set to "switch until released". (Of course you probably don't need the NOT, simply place your one-time code into the FALSE case )

Using an NDS statement for a SQL stament run only once in a proceudure
Hi,
We're using Oracle 11.1.0.7.0.
I'm going through code written by someone else. In this package they're using NDS for every SQL call whether it gets called multiple times or just once. Is that a good thing?
I thought NDS was only reserved for SQL statements that get called over and over again in a procedure with possible varying 'WHERE clause' variables and so on...
Is there ANY benefit to using NDS for SQL queries called only once in a procedure?
ThanksThere is no benefit unless you want to turn PL/SQL into SQL*Plus (parse once, run once)
Procedures exist to make sure : parse at compile time, run many times.
The code is shooting itself in its own foot.
Or the developer must have got hold of Tom Kyte's unpublished one chapter book 'How to write unscalable applications'.

Mass activity running only once for custom parallel object
Hi
I have created custom parallel object EXT_UI and created mass activity for this but the report in triggered only once and not going for second interval .
Can any one help me out in this.
Thanks in advance.
Chetan
Message was edited by: CHETAN N P
Mass activity is running fine for standard object ANLAGE but not for custom one
Please share me steps to be followed in creating custom parallel object.
Regards,
ChetanHi Chetan,
I think you need to make changes in the Events which gets triggered by the mass activity.
Can you let me know the mass transaction code for which you have customised the activity,
Thanks,
