The following procedure retrieves the argument value for collection, object, and REF instances of calls stored in the deferred transactions queue. This procedure assumes that the call number and transaction id are available. The user who creates the procedure must have EXECUTE privilege on the DBMS_DEFER_QUERY package and must have CREATE Interrupts and DPCs (deferred procedure calls) are related to hardware and driver resource usage. If the processors of a system are consistently spending more than 10% of their time servicing interrupts ( \Processor(*)\% Interrupt Time ) or DPCs ( \Processor(*)\% DPC Time ), then it is worth gathering an ETW trace to investigate. Deferred Procedure Calls (DPCs) are a commonly used feature of Windows. Their uses are wide and varied, but they are most commonly used for what we typically refer to as “ISR completion” and are the underlying technology of timers in Windows. Jun 29, 2005 · deferred procedure calls and GPU heat Ok, this forum helped me figure out why my system was dogging down while playing video games. I am running a Dell laptop XPS M1210 with a NVDIA GO GPU. In monitoring the system during video game play, I also noticed that when the system would dog down the DPC would jump to a high percentage of the CPU load.
nvidia geforce gtx 750ti 2gigs gpu and the system interrupes-Deferred procedure calls and interrupes service routine on my rig is running at 0.24%,and i think thats high,but after a little research its running at norm,you on the other hand your rig 45% is quit a bit or resources and menory,yes check all your drivers and do update you chipset
May 05, 2013 · In addition to thread dispatching, the kernel also processes deferred procedure calls (DPCs) at this IRQL. A DPC is a function that performs a system task—a task that is less time-critical than the current one. The functions are called deferred because they might not execute immediately. FYI, I use PowerSDR, a Software Defined Radio application that is used to operate a Flex 5000A amateur transceiver. This application uses real-time digital signal processing and needs to operate in a Windows environment with reasonably low duration Deferred Procedure Calls (DPC).
This example builds a deferred call to the HR.HIRE_EMP procedure in the ACCTS_REC schema. This HIRE_EMP procedure takes three arguments. No destination is specified for the deferred call, so the destination must have been specified using one of the other methods outlined . All deferred remote procedure calls are recorded in the DefCall view.
Windows 7: High CPU usage due to system interrupts (Deferred procedure calls and interrupt service routines) Submitted by Druss on Sat, 2009-12-05 21:47 Windows 7, much as I enjoy using it (although the shine has worn off a li'l bit), has a few niggles. Introduction. Just a little comparison between Asynchronous Procedure Calls (APCs) and Deferred Procedure Calls (DPCs). What are these things? One of the design goals of Windows is to remain at elevated IRQLs for the shortest amount of time possible. Dec 08, 2009 · How to get the cause of high CPU usage by DPC (Deferred Procedure Call) and interrupts?Ok, you found this guide, because you see this:in Process Explorer/Hacker or you run the DPC Latency Checker tool an see this:(Attention: If you use Windows 8, dont use the DPC Latency Checker tool.
