Low priority and high priority queue

Hi
we have high priority and low priority queue's. Functionality wise i know that time critical messages will be sent through high priority queue's and low priority messages will be sent
through low priority queues. But like to know what technicality makes this separation of
low priority and high priority queue's ? The crus of the question is what technical setting(s)
makes the queue as high priority and what technical setting(s) makes the queue as low priority
queue.
Thanks

I am talking abt queue prioritization on Integration eninge only.
I am good with queue prioritization and am able to successfully implement
the same. We are using only PI7.0.
My question is what is the technical difference between high priority
and low priority queues ? what technical setting makes it a high priority
queue and what technical setting makes a low priority queue ?
Your answer:
how the system reacts to new messages if almost all queues are already blocked
for some types of messages
My comment: what setting makes the system to behave like that ? what property
of that queue makes them to behave like that ?
Thanks

Low FPS and high contrast footage suffering on TVs

There are two problems I'm running into here:
One is that the motion on cuts with low FPS becomes very "choppy" ONLY when viewed on a TV. You could also describe it as having ghost trails or "flickering." This applies both to cuts which I've slowed down (without using frame blending) and to cuts which I've deliberately lowered the FPS (to give it a certain look) without slowing them down.
The second is that certain cuts seem to cause the picture to randomly... resize when viewed on a TV. I've noticed it mostly occurs on cuts with some very bright areas combined with very dark ones. I noticed it when the artificial widescreen that I applied to the cuts seem to shrink for a few frams at a time and then "revert" to it's natural position. I later confirmed that the entire image, not just the black matte, was resizing. On certain cuts where the resizing is more abrupt (like when gun flashes are present) it can make you VERY sick!
Since I use NTSC DV at 720x480, I went ahead and manually set the field dominance region to the lower. That didn't help, so I raised the bitrate (quite substantially too, although still under 9.8) and told it to do a Two Pass VBR. Still no luck.
Some other things I've tried: Setting motion detection to best, using iDVD, using different DVDs with differing quality, using different TVs, using Build/Format with a new folder instead of just Burn, and other random things that never really had any hope of succeeding.
This is my first time asking a question here for DVD Studio Pro, so if you need any technical information about the project itself just ask.

A side question (still eagerly awaiting an answer to
my original): How do I force DVD Studio Pro to
re-encode?
First try deleting your video_ts folder.
Following is conjencture based on a similar problem I had and what worked for me, but truth is, I don't really know why it worked -- If deleting the video_ts folder doesn't do it, see if there are .m2v files created by your project. DON'T DELETE THEM, just hide them. If DVDSP asks for them, put them back. If DVDSP doesn't ask for them, it might force a re-encode.

Which configuration is better: higher GHz and lower RAM or lower GHz and higher RAM?

I want to buy a new iMac. If all other factors are the same, including price, which configuration is better?
21.5" iMac (late 2012) $1699
3.1GHz Intel Core i7 Quad-Core
8GB of 1600Hz DDR3 RAM
--vs--
21.5" iMac (late 2012) $1699
2.9GHz Intel Core i5 Quad-Core
16GB of 1600Hz DDR3 RAM

A faster CPU gets the work done faster.
More RAM deals better with large chunks of work (= large files) and multitasking (more apps open simultaneously).
Fusion Drive is a an acceptable compromise to get the speed of SSDs and the affordable space of HDDs for as long as SSDs in the total target size are so astronomically expensive.

Is it possible in IOS to have two static routes for the same subnet, one a higher priority and "failover" between the 2?

Hi All
Is it possible in IOS to have for a particular subnet:
a) Two static routes?
b) Make one static route a higher priority than the other?
c) If one static router "goes down", failover to the lower priority static route?
We have a l2tp/vpdn connection to a supplier which can be accessed via two vlans/routes. I would like to make one route the preferred one but the "route" to failover if the preferred route goes down.
Again, many thanks in advance for all responses!
Thanks
John

Hi John,
Hope the below explaination will help you...
R1(config)# ip route 0.0.0.0 0.0.0.0 2.2.2.2
R1(config)# ip route 0.0.0.0 0.0.0.0 3.3.3.3 10
If you notice the Administrative Distance for the secondary route pointing to ISP2 is increased to 10 so that it becomes the backup link.
The above configuration with just two floating static routes partially accomplishes our requirement as it will work only in the scenario where the routers interfaces connected to the WAN link are in up/down or down/down status. But in a lot of situations we see that even though the links remain up but we are not able to reach the gateway, this usually happens when the issue is at the ISP side.
In such scenarios, IP SLAs becomes an engineer's best friend. With around six additional IOS commands we can have a more reliable automatic failover environment.
Using IP SLA the Cisco IOS gets the ability to use Internet Control Message Protocol (ICMP) pings to identify when a WAN link goes down at the remote end and hence allows the initiation of a backup connection from an alternative port. The Reliable Static Routing Backup using Object Tracking feature can ensure reliable backup in the case of several catastrophic events, such as Internet circuit failure or peer device failure.
IP SLA is configured to ping a target, such as a publicly routable IP address or a target inside the corporate network or your next-hop IP on the ISP's router. The pings are routed from the primary interface only. Following a sample configuration of IP SLA to generate icmp ping targeted at the ISP1s next-hop IP.
R1(config)# ip sla 1
R1(config)# icmp-echo 2.2.2.2 source-interface FastEthernet0/0
R1(config)# timeout 1000
R1(config)# threshold 2
R1(config)# frequency 3
R1(config)# ip sla schedule 1 life forever start-time now
The above configuration defines and starts an IP SLA probe.
The ICMP Echo probe sends an ICMP Echo packet to next-hop IP 2.2.2.2 every 3 seconds, as defined by the “frequency” parameter.
Timeout sets the amount of time (in milliseconds) for which the Cisco IOS IP SLAs operation waits for a response from its request packet.
Threshold sets the rising threshold that generates a reaction event and stores history information for the Cisco IOS IP SLAs operation.
After defining the IP SLA operation our next step is to define an object that tracks the SLA probe. This can be accomplished by using the IOS Track Object as shown below:
R1(config)# track 1 ip sla 1 reachability
The above command will track the state of the IP SLA operation. If there are no ping responses from the next-hop IP the track will go down and it will come up when the ip sla operation starts receiving ping response.
To verify the track status use the use the “show track” command as shown below:
R1# show track
Track 1
IP SLA 1 reachability
Reachability is Down
1 change, last change 00:03:19
Latest operation return code: Unknown
The above output shows that the track status is down. Every IP SLAs operation maintains an operation return-code value. This return code is interpreted by the tracking process. The return code may return OK, OverThreshold, and several other return codes.
Different operations may have different return-code values, so only values common to all operation types are used. The below table shows the track states as per the IP SLA return code.
Tracking
Return Code
Track State
Reachability
OK or over threshold
(all other return codes)
Up
Down
The Last step in the IP SLA Reliable Static Route configuration is to add the “track” statement to the default routes pointing to the ISP routers as shown below:
R1(config)# ip route 0.0.0.0 0.0.0.0 2.2.2.2 track 1
R1(config)# ip route 0.0.0.0 0.0.0.0 3.3.3.3 10
The track number keyword and argument combination specifies that the static route will be installed only if the state of the configured track object is up. Hence if the track status is down the secondary route will be used to forward all the traffic.

Queues, Priority and SLOs - Some confusion

Hello all,
Please bear with me on this one, I'm currently trying to get my head around Queues and SLOs with regards to priority. My existing helpdesk software uses a lot of odd terms to describe all these items so I'm having some trouble while setting up SCSM
2012.
Some background; we don't use tiers of helpdesk but rather departments (Desktop, server, infrastructure etc) so any job comes along unassigned and anyone can pick it up and assign it to the correct department.
The question I have is that if I set a incident's priority using the urgency and impact, do I need to do an SLO for each level (1-9) of the priority and set a target and warning threshold for each?
Cheers

You will have to ask yourself some questions first.
Do you want to use all 9 priorities?
Do you want to apply an SLO to all (9) priorities? Do you really have a SLA agreement that applies to all possible incidents (and/or service requests)?
Normally you would only apply an SLO for the most critical incidents, or incidents or other requests you have a standard solution time for (like something that is (semi)-automatic.
Do you want to apply a SLO to all types of incidents (again look at available SLA agreements)
Lastly there is not much point in having SLOs if they are not respected
You can have different entry-points on the service manager portal that allows you to automatically route the request to the proper team/department/support group/whatever.

ThreadPoolExecutor and using priority to determine what threads will run

Hello,
I am fairly new to Java, so I apologize if there is an obvious answer.
The ThreadPoolExecutor is a great class for thread management. What I would like to do is have a priority scheme that would determine what thread should be run next. For example, let's say I have 100 threads and a limit of 20 threads. Each thread that is executed should have a mechanism to indicate a priority. When a thread becomes available in the pool, the priority value should be checked to determine which thread to run. This would allow me to get important tasks completed quickly. Right now it appears that there is a FIFO order to threads. I tried wrapping the runnable object in a Thread, but that didn't seem to have an effect.
I am using a Fixed thread Pool:
      loThreadPoolExecutor = (ThreadPoolExecutor) Executors.newFixedThreadPool(MAXTHREADS); (MAXTHREADS=20)I have tried creating a PriorityBlockingQueue with a comparator that compares the thread priority, but nothing seems to work.
public Constructor() {
loThreadPoolExecutor = new ThreadPoolExecutor(MAXTHREADS,MAXTHREADS*2,0,TimeUnit.SECONDS,new PriorityBlockingQueue(11,new PrvComparator()));
    private class PrvComparator implements Comparator {
          public int compare(Object o1, Object o2) {
               // TODO Auto-generated method stub
               Thread t1 = (Thread) o1;
               Thread t2 = (Thread) o2;
               System.out.println("P1="+t1.getPriority()+ " P2="+t2.getPriority());
               if (t1.getPriority()<t2.getPriority()) return -1;
               if (t1.getPriority()>t2.getPriority()) return 1;
               else return 0;
               //PriorityBlockingQueue
          }I would appreciate any help.

What are you trying to prioritize? The order on which tasks come off the work queue, or the order in which they get completed?
Doing the first is simple but restricted. Your tasks are Comparable and define their own priority and you use a PriorityBlockingQueue. But you are restricted to using the execute() method with Runnable's that are Comparable. submit() will wrap the task in a FutureTask that isn't Comparable and so will cause a ClassCastException.
Doing the second is difficult. Even if your threads have different priorities then don't queue for tasks in priority order, so the thread priority when taking a task is irrelevant. You could change the thread priority based on the priority of the task once it starts executing. But Thread priorities are only a hint to the scheduler that you think Thread A is more important than Thread B. On some platforms priorities will have little observable effects - whereas on other it can be drastic if you use priorities that are too high or too low. The mapping from Java priority to OS thread priority is platform specific. See for example http://java.sun.com/javase/6/docs/technotes/guides/vm/thread-priorities.html

How can I give the "user interface thread" higher priority?

We do alot of activex calls to front panels. We need to increase/decrease the priority of the user interface thread to resolve our thread problem. Anyone know how to do this?
Chuck

Hello,
As P.M. was saying, you can adjust the thread priorities
through the VI Properties dialogue.
Another place to modify the multithreading system in LabVIEW is a VI
located at: [LabVIEW Directory]\vi.lib\Utility\sysinfo.llb\threadconfig.vi. However I do not think this will remedy any
problems you are having.
From a Multithreading in LabVIEW tutorial (http://zone.ni.com/devzone/conceptd.nsf/webmain/d2e196c7416f373a862568690074c759)
Priorities in the User Interface and
Single-Threaded Applications
Within the User Interface execution
system, priority levels are handled in the same way for single-threaded and
multithreaded applications.
In single-threaded applications and
in the User Interface execution system of multithreaded applications, the
execution system queue has multiple entry points. The execution system places
higher priority VIs on the queue in front of lower priority VIs.
If a high-priority task is running and the queue contains only lower priority
tasks, the high-priority VI continues to run. For example, if the execution
queue contains two VIs of each priority level, the time-critical VIs share execution time exclusively until both finish.
Then, the high priority VIs share execution
time exclusively until both finish, and so on. However, if the higher priority
VIs call a function that waits, the execution system removes higher priority
VIs from the queue until the wait or I/O completes, assigning other tasks
(possibly with lower priority) to run. When the wait or I/O completes, the
execution system reinserts the pending task on the queue in front of lower
priority tasks. Refer to the Synchronous/Blocking Nodes section for a list of
asynchronous functions that wait.
Also, if a high priority VI calls a lower priority subVI,
that subVI is raised to the same priority level as the caller for the duration
of that call. Consequently, you do not need to modify the priority levels of
the subVIs that a VI calls to raise the priority level of the subVI.
Thus changing the priority of your VI will change the
priority of UI calls for that particular VI.
Again, I caution you because I suspect that if you are having problems
with your application not running correctly, I do not believe that manipulating
the thread priorities will resolve these issues.
Hope this helps,

Configuring QoS for FIOS Router MI-424WR: Traffic Priority and Shaping

Please only read on if you are an experienced internet user familiar with setting the advanced QoS and Firewall settings for the MI-424WR and make use of wireless adaptors from a PC to provide connectivity.
This is my first post and my first week since I moved from Time Warner Cable over to FIOS for iNet (plus HDTV and phone).     While all my services work, the router as delivered and setup is not optimum for internet quality of service. Instead it was probably out of the box optimized for HDTV and telephone to satisfy most customers and reduce support overhead.   The average FIOS consumer is multimedia sensitive, but that is not so in my genre of internet consumer.   Here in lies the core of my reason for seeking help from like minded and experienced users in this community.
One of the main driving forces in my switching to FIOS was to improve my multiplayer gaming experience where ultra low ping latency and high upload data rates dramatically affect the quality of connection and thus gameplay.    The cable internet service from TimeWarner was providing solid 2MB/1MB down/up data rates with no issues like what Im having now with FIOS.   Again the reason for the switch was both financial and in hope of gaining better data rates and quality of service.   Now with FIOS Im getting about 24/15 down/up data rate on the Extreme FIOS 25/25 plan when measured from my house to Los Angeles server (50 miles away) via Speedtest.net or DslReports.com/tests.     Latency wise, the ping has gone down from 150 to 50ms when measured to my friends who I connect to online that are on the East coast.   The data rate and latency has greatly improved in going from Cable to FIOS.   So far, so good.
Where the problem shows up now, is that now I get an internet "hiccup" every 5-10 minutes that lasts about 1/2 to 2 seconds.   For the average internet user that just streams multimedia or cruises on the net; this is probably undetectable or noticed.   I never had this problem over the same PCs connected wirelessly to my DLINK DGL-4500 Gaming Router when my ISP was TimeWarner's cable service.    Now, using the FIOS and MI-424WR router with everythings being the same; Im experiencing this degregation in quality of service.    Even putting the PC's IP into the DMZ doesnt make any difference, so it is not related to port forwarding.    The issue is squarely in the lap of FIOS and this router as delivered and configured.    This is where the "game" is a foot, and where I need expertise in an area Im new to.
I am not new to being hands on with inet trouble shooting asI have been setting up my own home network (I work from home over VPN to work) for decades; I would like to leverage the skills of those who are experts in the area that I think can address this issue.   That being QoS and the other device class mechanisms of this router.   Its my guess that this periodic hiccup can be minimized and even eliminated using these advanced features of this all-in-one TV/iNet/Tele router.
With that context being laid down, this hiccup doesnt show up if:
a. I connect two PCs connected to the same ethernet hub of the MI-424WR (traffic just over the LAN and not WAN)
b. When I was on Cable with my own gaming router wirelessly DHCP connected to my PC and using port forwarding or using the DMZ.
The hiccup does exist when:
a.  Going from internet through the MI-424WR to the wireless DHCP connected PC with port forwarding
b. Even putting the wireless DHCP connected PC into the MI-424WR's DMZ has no effect
I did read the manual and tried some QoS pritority and shaping and managed to reduce how often the hiccup occured, but I was just making guesses at the settings.   I put in the IP for the PCs I use for my gaming applications (which are very ping and jitter sensitive) into the QoS priority (value 7) and shaping GUI.    Im hoping someone with experience can tell me exactly how to use it and what settings to input.   Im not clear on the device and connection types offered in the QoS menus.
Another thing, is I couldnt find settings for the turning on/off the ICMP echo.   But I assume this is on because it can be pinged by folks on the net to my WAN IP.
Here is the manual for the Verizon provided M424WR router (Current Version of firmware: 20.10.7)
download link
Here are the QoS traffic priority and shaping values Ive been experimenting with:
Click to view QoS Traffic Priority
Click to view QoS Traffic Shaping
And why it matters to have a solid and stable inet connection for internet gaming? The hiccup causes slewing or jitter which equates to positional errors in the 3D world that ruins the smooth gameplay that is needed for high end gaming.
Heres a snapshot of me flying the wing of another flight simmer who is on the East coast and me on the West coast.

That's not accurate. VZ telephone service does not go through the Actiontec. Also, there are no default settings for QOS in the Actiontec since QOS is rarely needed with FIOS upload speeds.

   You should not be experiencing periodic "hiccups". Something is clearly amiss.

Lets see. The issue shows up on a wireless connection, but not a wired connection. You think this is a QOS issue and not a wireless issue why? Have you tried changing the wireless channel? It very possible you have neighbors on the same channel. Is the DGL-4500 wireless still on? Could that be interfering?TMAS wrote:

The settting to enable/disable ICMP echo is on the Firewall/Remote Administration page.

The traffic proirity settings you linked are applied only to your wireless connections. QOS between the router and your wireless PC will only serve to prioritize traffic between the router and that PC and have no affect on your internet traffic. Assuming you are not running browsers, VOIP and other traffic from that PC while you're gaming, then that will not accomplish anything. i.e. You're giving your only traffic highest priority, but that traffic is not competing with anything (except other nearby wireless connections on the same channel).
On the traffic shaping screenshot, you have broadband ethernet checked, but according to your other thread, your WAN connection is Broadband Coax, not Broadband ethernet.

EIM Auto pushback - requeue at higher priority?

Hello,
In our EIM 4.3.2(8) implementation (ICM Enterprise integrated queues and agents), all new and incomplete activites auto-pushback to queue after 8 hours (overnight generally). The problem with this is, they're getting pushed to the back of the queue. I'd like to have all auto-pushback emails queue at a higher priority so that during days of high email volume, we don't get stragglers that keep getting pushed to the end of the queue while newer emails get handled.
I saw this:
http://docwiki.cisco.com/wiki/Transferred_Emails_Get_Sent_To_End_of_Queue
and thought maybe I could pull some Activity related column through to ICM to act on to change the priority... Not sure what I should use though. I considered looking at the "WHEN_CREATED" field and upping the priority in ICM if that's more than a day ago, but I wonder if there is a simpler way to do this.
Any help you can provide would be greatly appreciated.

New tasks are sent from EIM to ICM in order queue priority, activity priority and oldest - in that order. While sending new task there is no differentiation between new email first time in queue Vs email which is auto pushed back to queue, if queue and activity priority are same then oldest activity criteria will be honored.
There is no other way in default EIM product to push auto pushed back emails ahead of others.

High Priority Items Inventory Alert

Hello All --
Thoughts on this...
I would like a report that indicates when we are either low or out of stock of inventory. However, I don't want a general report that just tells us when ALL inventory is low or is out of stock.
Rather, we would like the report to update us only when certain high priority products are low or out of stock.
What's the best way to go about doing this?
Thanks!
Mike

Hi Gordon --
In answer to your question, the query shows the following:
Style #...Color...Total Qty...L Size Qty..L Size %
This is very close to what we are looking for. The gap is that it only shows the data for a single size -- Large. It sounds like we would have to run separate Queries for each of the other sizes.
Ideally, the Query would indicate whenever 1 or more of the sizes fall below the minimum % (or qty) set. Initially, I envisioned it looking something like this:
Style #...Color...Total Qty...S Size Qty...S Size %...M Size Qty...M Size %..., etc. for rest of sizes.
However, this may not be the best format and a lot of data to look through. You suggested an alternative which I am certainly open to...just not sure what you mean by it.
The ultimate goal is to have a report that will help us identify when inventory falls below a critical level (either by % or amt -- % would be more accurate as sizes are not purchased equally) ) for high priority products.
Bishal -- thanks for the suggestion. Have not set up the alert function - thought a query would better achieve what we are looking for as it is all combined in a single report.
Gordon - can you send example of Query you are suggesting?
Thanks!
Mike

Create at runtime a job to run at the central instance with high priority

Hi All
Using the function modules ( job_open, job_submit and job_close ) or ( job_open, submit via job jobname number jobcount, job_close) I need that this job runs in the central instance and with high priority.
I would like to know how to inform it using the statements above? How to pass the parameters to make the job run in the central instance with high priority?
I would appreciate any help.
Thanks in advance.

Hi
I hadn't realized about the parameter TARGETSERVER of the function module JOBCLOSE. I am going to make some tests.

Why is time-critical thread not interrupting sleepless high priority thread?

Hello,
I have two threads running in the same execution system on a real-time PXI platform. The time-critical thread sleeps using "AI Single Scan.VI", and acquires my data at a rate of 8000 Hz.
I have a slower high priority process that calls a DLL function to calculate some filter coefficients. This function call takes longer than 1/8000 s to complete, and runs in a loop, executing as often as it can (with new data from FIFOs).
I expected the time-critical thread to interrupt the the high priority thread without problem.
I am finding that unless I insert a LabVIEW delay (for example a wait for x ms VI) in the loop, the real-time system stops responding. With a small delay (ie 1 ms), t
he acquisition completes, and a FIFO shuts down the loop of the slow process.
Why do I need a labVIEW delay in the high-priority loop, when the DLL function call itself is quite slow? Even without a DLL call, I would expect the time-critical VI to interrupt, finish its data acquisition, and shut-down the high-priority thread using its FIFO.
Any suggestions?
Thanks in advance,
Frenk

Here are a couple things to try/check:
1) Check the call library node in your high priority VI. If it's orange (runs in UI thread), your high priority VI is actually switching to the UI thread every time your dll runs. That alone is not a problem. But if your TC VI tries to update any control terminals, the TC thread will switch over to the UI thread to access UI resources, possibly while the dll within your high priority VI has a lock on those resources. Why does the dll have a lock on UI resources? Because it was running in the UI thread and got interrupted by the TC thread before it finished doing its business. Not likely, but possible.
2) There's another possible reason you're seeing this behavior. If the TC VI and the high VI call a mutual subVI, the subVI will be elevated to ALWAYS run in the highest priority thread irrespective of the actual caller (in your case, it's the the TC thread). Even when the *high priority VI* calls the mutual subVI, that subVI runs in the time-critical thread, which means there's a thread switch from high to TC, then back to high after the subVI finishes. And because high and TC VIs are in the same exec system, that mutual subVI will always run in the 1 and only TC thread alotted to that exec system.
So, while your TC VI is running, you're in the TC thread. While, your high VI is running, you're in a high non-TC thread, and when your high VI calls the mutual subVI, you're again in the TC thread until the subVI finishes.
So how could this arrangement cause your TC VI to become starved by the high VI? If your TC VI wakes up while the high VI is in the middle of running the mutual subVI, the TC thread responsible for running the TC VI is actually busy (in the middle of running the subVI in your high VI!!!), so the TC thread cannot run your TC VI until it finishes running that mutual subVI.
The fix: make your TC VI run in a different exec system. It will be given its own TC thread that no one else can mess with. When TC VI wakes up, it's guaranteed a TC thread.
I think there's a good reason behind why a mutual subVI ALWAYs runs at the highest priority of all its callers, irrespective of the actual caller's priority...but I can't think of the reason at the moment.

Listing Items based on criteria e.g. High Priority Items First.

Hi,
One of our customers have a need to List High Priority Items first on the WebTools site.
Let's take two ItemCodes for example: Printer001, and, Monitor001.
>> If these two items are included in the same category then Monitor001 will appear before Printer001 as WebTools sorts in alphabetic ascending order;
>> But, our customer wants Printer001 to appear before Monitor001 as it is an Item higher in priority that Printer001.
I can think of two possible solutions:
1/2) Prefix Items with a number or letter to have it appear first in the WebTools default sort order. E.g. Rename "Monitor001" as "AMonitor001". This will not be possible for existing Items in SAP, so it doen't solve the issue,
Or,
2/2) Customize the Default WebTools Item List block to sort Items based on a User Define field called "pririty". Which might require a lot of effort.
Please advise if anyone else has solved similar issue and how.
Thanks very much for your replies in advance.

Hey Kafil ... I think you may be stuck modifying the parts list page or creating something from scratch. I'm not aware of an easy way to do this out of the box.
