Execution priority for application

The executable of my application doesn't reflect the priority I set in VI Properties (Win XP). Is there an .ini setting I can make to have the exe run at background priority (lowest)?

You may want to take a look at this. Setting the priority within the options of LabVIEW will not affect its priority within XP. LabVIEW is given priority when it starts running on XP. You can programmatically call an XP DLL and make it give you higher priority. This KnowledgeBase on NI's website describes how to do that.

(How) Can I change vi execution priority at runtime

Hi all,
I am using Daemons (free running VI's) and I communicate to them through Queues.
They are part of my device driver architecture and use a producer architecture (For Acquisition) or a consumer Architecture (For Control)
I have a single Daemon VI to which I deploy a "Device Object" using a Polymorphic class implimentation.
This implimentation has one subtle shortfall,
I am not able to change the execution priority at launch
There is a property node that taunts that it is possible but the help (And run time Error message) says it not available at runtime.
Does anyone know of an alternative method?
Here are what I have thought of to-date:
1. Have 5 different daemons each with a different priority [Distasteful for Code maintainance]
2. Make Priority Low, and ensure that at least 1 VI in the driver has a high priority [Not sure if it works, obscure implimentation]

Solved!
Go to Solution.

Ben,
I debated wheter or not to put more information in my post, I didn't want to bore my potential support Sensei's.
Here Goes:
As I hinted in my initial post, I am devoloping a set of drivers for my large application.
I am using a compact Field Point and am under some fairly aggressive rescource pressures.
Heavy RS422/485 Serial Comms @115200, Digital Acquisition and some heavy data processing.
My understanding of this type of system (Jump in if you have any improvement suggestions):
Priority #1 [High Priority](Producer) is to get data out of the Acquisition Buffers and in my case, perform Writes/Outputs/control activities as demanded.
So any "Hardware" Device Driver Daemons that I lanuch need to be run at high priority. The drivers should do as little as is necessary so as not to hog this thread. Event based architecure is preferred over polled.
These drivers tend to be launched as Daemons so that they can run in a different priority and are not affected by other activities, they are inherently asynchronus.
Priority #2 [Above Normal Priority](Consumer->Producer) Protocol/state interpretation/Data Filtering.
Now that the data is out of the buffers, what does it mean? is it a valid communicationss message, was there a button pushed, is there an object in the transducer field.
These functions may take a bit longer (but not too much) to execute, but as they are on a lower priority, buffers can continue to be emptied.
These "filters" tend to be launched as Daemons also so that they can run in a different priority and are not affected by other activities they are inherently asynchronus.
Priority #3 [Normal Priority](Consumer) Number Crunching, Heavy Lifting , Control determination..
An event has occurred and some caculation interpretation and potentialy control needs to be performed, Do it.
Tend to be event based and as there are multiple stimulii tend to be best managed by an event structure. This allows for interaction with the front panel as well (should the need arise).
Priority #4 [Low Priority](Slip-Scheduled) User interface/User Data/Report Generation.
Who Cares if it is a bit late, Work away in background. In the case of user updates, they can slip later and later, no need to catch up.
For others reading this thread, I found This Module Help invaluable in understanding how Labview manages execution priority.
Theory Done, I am essentialy a lazy programmer, and don't like to write and maintain too many different .vi's if I can help it, <Rant> ESPECIALY IF THEY ARE THE SAME VI WITH A DIFFERENT PRIORITY! </rant>.
So I have written one Daemon and one Daemon manager (to rule them all). For each driver I require, I launch a Daemon, passing the "Base" Class object to the Daemon prior to Run, I rely on the override capability of polymorphism to choose the correct methods.
My "Base" Driver class contains all of the functions required for operation. I use it as an enforcable template for future driver development (It also auto fills in my Icon's wich is great for a Lazy Programmer like me).
I have established that my protocol driver (Priority #2) is compatable with the same daemon Architecture from above, Instead of looking at hardware, it monitors a Queue/Notifier/User Events from the lower level hardware driver.
I was very smug when I figured that one out, until.... I realised that they would need to be launched at different priorities to respect the RTOS, and thus my question.
I am not trying to change priority per-se, but to choose one prior to launch and then to leave it.

awrsqrpt.sql is showing multiple executions plans for a single SQL statement. How is it possible that one SQL statement will have multiple Executions Plans within the same AWR report.If you're using bind variables and you've histograms on your columns which can be created by default in 10g due to the "SIZE AUTO" default "method_opt" parameter of DBMS_STATS.GATHER__STATS it is quite normal that you get different execution plans for the same SQL statement. Depending on the values passed when the statement is hard parsed (this feature is called "bind variable peeking" and enabled by default since 9i) an execution plan is determined and re-used for all further executions of the same "shared" SQL statement.
If now your statement ages out of the shared pool or is invalidated due to some DDL or statistics gathering activity it will be re-parsed and again the values passed in that particular moment will determine the execution plan. If you have skewed data distribution and a histogram in place that reflects that skewness you might get different execution plans depending on the actual values used.
Since this "flip-flop" behaviour can sometimes be counter-productive if you're unlucky and the values used to hard parse the statement leading to a plan that is unsuitable for the majority of values used afterwards, 11g introduced the "adaptive" cursor sharing that attempts to detect such a situation and can automatically re-evaluate the execution plan of the statement.

An error has occurred during report processing. (rsProcessingAborted).. Query execution failed for data set

Hi All,
I'm facing a strange problem..
I've developed few reports. they are working fine in develop environment. after successfull testing they were published on web.
in web version, all reports are executing for first time.. if I change any of parameters values or without chaning also..
if I press "View Report" following error occurs..
An error has occurred during report processing. (rsProcessingAborted)
Query execution failed for data set 'dsMLGDB2Odbc'. (rsErrorExecutingCommand)
For more information about this error navigate to the report server on the local server machine, or enable remote errors
please suggest any alternative ways to overcome this issue
thanks in adv.

in my case the problem is
one virtual machine is for developers
other for testers
in developers i created a report, then save like *.rdl and copy to testers machine, does not work there

How to set the priority for Commit Server?

Hi all,
I want to know how to set up the priority for committing documents.
I'm having two different odc applications and i want to commit documents belongs to one application (URGENT) as soon as it has complete the indexing. (I'm running commit server every second for this (URGENT) application).
But once the commit server start to commit batches belongs to one application it continues until finishes, and then only it switch to the URGENT application even though indexed documents are there.I have tested with batch priority, Batch status fields in commit server.
What is exactly happen in setting batch priority ?
How do i switch commit serve to run urgent batches (which is belongs to another application) as soon as indexed??
I can use ODC or ODDC.
Thank You.....

Don't worry - I'm more think aloud, so it is more a hypothesis than a solution.
You write that
We are using ODC to Index the documentsWhat exactly does this mean? If it means that a user types in metadata values, then you could take a look whether those metadata are needed for the item to be checked in (like the mentioned security group), or whether it is "other" metadata (e.g. supplier, invoice number, etc.) that you could, in theory, fill in in your application in IPM - imagine that you use IPM to check in the document and all you have is a TIFF.
Btw. you also write that
(we) use Input agent to sent documents to IPMI thought that ODC (Commit Profile) does this work for you, or not? If you use ODC to commit to a disk, and Input agent to get it from a disk to IPM, how about using a direct commit profile to IPM?

OBI report execution priority.

Hi,
Is there any way to set report execution priority based on user groups? For example if group with higher priority needs to execute a report, then server will free the stock or limit execution for groups with lower priority.
Thanks,
Adam

No. If you query comes in less that 1 second then you got nothing to worry about. I haven't seen a single DWH where users would worry about queries returning in milliseconds.

Is there any way I may set low resources priority for a specific job or even all SQL jobs?

Is there any way I may set low resources priority for a specific job or even all SQL jobs?
Our database is quite big and everything works OK and very fast, except SQL jobs which are used mainly for maintenance purposes.
I have one specific job which runs for 2 minutes and takes a lot of resources which may affect execution of other stored procedure which should be executed fast.The worst part is that this job has to be executed during the most active working hours. It does
not matter for me how long will it take to execute this job. I just do not want it to use so much resources.
Also I noticed when SQL backup job (takes about 4 minute) is scheduled it also takes a lot of resources and sometimes because of that I am receiving "login timeout" error on my web site.

depending on you sql server version and edition, you can use resource governor and limit the cpu and memory.
in most typical cases , you can use the session user name and times and classify the how much cpu and memory they can use. refer : https://msdn.microsoft.com/en-us/library/cc645892.aspx
but in your case, the problem seems to be with the maintenance jobs which could run as sql server service account.
also, if the backup are third party tool backup, you can specify the priority level and other options etc to make it less priority.
it is possible to do that even with native backups such as specifying the limiting buffercount, max transfer size, if the server is memory pressured. sometimes, stripping the backups to multiple sets across different devices, could help as well. even though
stripping the backups can introduce another complexity.
may be you need to rethink you back up\recovery strategy.
Hope it Helps!!

Does un-checking "Allow Debuging" in VI properties- execution improves overall application performance?

Does un-checking "Allow Debuging" in VI properties->execution improves overall application performance?

> Does un-checking "Allow Debuging" in VI properties->execution improves
> overall application performance?
Yes, though it is hard to predict by how much. When debugging is
enabled, after each node on the diagram there will be a small amount of
compiled code to test if the VI has a probe, a breakpoint, execution
hiliting, or the pause button is pressed. The code is quite small,
about two or three instructions, but if you have twenty nodes in a loop
and the nodes are doing simple math, these instructions could be 25%
overhead. For more complex nodes or datatypes, these instructions turn
into a fraction of a percent.
Turn it off and measure. If you have other performance problems, read
the documentation on the profiler and use it to help you find yo
ur
bottlenecks.

Changing Thread Priority for TimerTask

I am scheduling two different tasks which will run as part of a larger appln.
I am scheduling with the help of TimerTask and Timer class.
Now i want to reduce the thread priority for these one task say inside the run method.
Do I have access to reduce the thread priority for this If YEs How?
Thanks
Mum

This technique may be appropriate. But a word of caution - Java thread priorities do not necessarily affect the behavior of the OS in scheduling threads across processes. That is outside of the scope of the language and JVM specifications.
Also, if your delete task tends to use little CPU time itself (just issues a lot of SQL commands for instance) but causes the database server to consume a lot of CPU and/or I/O capacity, then adjusting the priority of the thread running that task will have little if any affect on the degree to which the delete task interferes with the other application.

Setting priority for WL Triggers

Hi,
We are developing a huge application using WL 5.1 and JDK 1.2.2. We have 5-6
Weblogic Scheduled Triggers that are running at different time.
The rest of the application almost comes to halt or slows down when the
triggers are scheduled. Is there a way to set priority for the those
Triggers? Like can i say in weblogic that run triggers in low priority? If
so, how?
Thanks for the help in advance.
regards,
Prabhakar Babu

At the current time, no.
Thanks,
Michael

Step By Step Example for Application Integrator for Yahoo or any kind of

All EP Expert,
I want to create yahoo or Gmail or any kind of url iView on which I can implement SSO for learning purpose on my Local laptop.
I have installed EP SP9 on my laptop.
I go through some blog and some discussion but I am not able to find below files mentioned in those blog.
1. AppIntegrator.zip file to find two files
2. com.sap.portal.howtos.webapp.par file
3. HowToUseAppIntegrator_en.pdf file
So I am not able to perform step by step instruction as mentioned in blogs.
Can any one provide me any kind of documents for EP SP9 for Application Intigrator functionality basically I am interested to integrate JAva base application in my portal with SSO but if any one can provide for Yahoo or Gmail for EP SP9 it will be a great help.
Thanks and waiting for some help on this form all EP experts.
I will reward full points for right answer.
Thanks in Advance.
Ashish.

Hi Mona,
Thank you very much for your prompt reply. I really appreciate if you can provide me exact location from where I can download "Application Integrator" zip file from which I can extract "com.sap.portal.howtos.webapp.par" file as describe in example PDF file. I tried very hard to find on SDN and "help.sap.com" but could not find it.
If you have it with you then please send it to me on my email ID [email protected]
Or please tell me exact location from where I can download it.
I give 10 points for this help.
Thanks in Advance.

APEX SSO and Load balancing: Could not determine workspace for application

We had a single HTTP Server serving APEX in a 10.2.0.2 database configured with SSO to be used by the developers. APEX has been registered as a partner application and the login url has been CA Siteminder protected so that the SM_USER details are forwarded in the header for the application to use for authorization. Everything is fine so far.
Now we have added a HTTP Server on another host and have it all set up for APEX and its pointing to the same database. APEX_ADMIN access works as normal, but applications previously using SSO now get the following error after entering the URL.
Expecting p_company or wwv_flow_company cookie to contain security group id of application owner.
Error ERR-7620 Could not determine workspace for application ().
Using HTTP Watch I find that the application is not even trying to redirect to the login page.
What is wrong here?

APEX has been registered as a partner application as described in
http://www.oracle.com/technology/products/database/application_express/howtos/sso_partner_app.html
In the meantime I found metalink document 368746.1 which describes the cause of this problem. Please read carefully what I wrote, it all works when the the new APEX web server is turned off in the server farm on the load balancer and directed through the original web server. When running regapp.sql the hostname in the listener token was using the virtual hostname. This works fine if the request comes from the original APEX server which proofs that there is nothing wrong with the installation and set up of SSO. When directing the request to the new APEX web server the APEX_ADMIN page still works only existing work spaces using SSO don't seems to work anymore resulting in a error as described in the subject.
As for metalink document 368746.1 naming the causes of this error:
- there are no duplicate entries in WWSEC_ENABLER_CONFIG_INFO$
-LISTENER_TOKEN clearly works for requests coming from the first web server
-theoretically the web server listener port could be changed from 7777, but port 80 needs to be maintained here as production is mimiced as far down as possible.
Is there some cache table which can be cleared? How is it that the flows schema (apex engine) can not find the work space when the request comes from a new web server which can however access the APEX_ADMIN pages.
anyone?

AP Payment User Responsbility's Data Group to be assigned for application as Payables or Payments?

Hi,
I am in version R12.1.3 . I have a requirement to create a user who must have access only to create payments in AP module.So when i try to define a responsibility for this payment user
there is a data group to be assigned. In this data group block for application there are 2 options i.e Payables & Payments? What should I select & what is the difference of selection one over the other?
Appreciate your help.
Thanks

Hi,
i did not see any difference .... I performed a test case, where i created a payment using the new responsibility i have created having data group application as Payments, the payment was successful ... Later i have modified the data group for this new responsibility from payments to payables, then the test payment i have made was also successful....
Not sure about its impact, may be i am having responsibilities which has full access, hence i cannot see the difference in my environment ....

Ivruksha
