Peak No. Of Requests/ Per Hour in BW

Suppose my cube gives performance of 5 Sec for a given query to run.
How does one estimate, assuming Bandwidth can scaleup, at what no. of peak requests (in per Hour or Per minute or Per sec) would the BW server show considerable performance degradation in terms of longer query runtime.
How much of this can be addressed by caching? Are there situations when Cache would get corruped due to high number of request, each potentially with differnt set of variable inputs?

As you said you don't have any email accounts it isn't email. Safari can drain the battery if left on a page that automatically refreshes.
Location Services can drain the battery - if you see an arrow in the top bar near the right then there is an app running in background and using location services.
Game Center can drain the battery even when it is closed.
Streaming apps, social networking apps (facebook, yahoo, skype, etc) can also drain the battery in sleep mode.

300 requests per hour reading from Application scope Good/Bad idea

I am saving some html in application scope & reading with
<cflock readonly.
Will it be a problem if more than 5 requests are made per
second?
Does deadlocks occurs with readonly-cflock?
Thanks

While creating/changing application scope variables in a
lock, I think there must be an exclusive lock. You must be careful
not to set any shared variable such as application inside a read
only cflock tag.
I also would suggest to check the usage of Application.cfc
and onApplicationStart method. You can set application default
variables and constants in onApplicationStart method in your
Application.cfc.

Cost Per hour, Costs per route not updating in S114 structure

Dear PM Guru's,
i am using MET unit system for vehicle consumption analysis. After completion of measurement documents and material issuance through IFCU, i checked the MCIZ report , but there i could not find the value of Costs per Hour, Costs per route information. I am requesting you all please guide me where i did the mistake either in "Configure measurement document updation" or calculation method?
I am eagerly waiting for replies.
regards
JKM

Its not possible to give any specific section where it might have gone wrong. Suggest you to check the complete configuration under Settings for Fleet Management. Also check the configuration in IMG - PM & CS - Information Systems - Configure Measurement document update

Average visits per hour

Post Author: PatchesPete
CA Forum: Formula
I need to generate a report that shows the average number of visits by hour of the day for the first quarter of 2008 for a time period of 7 AM - 11 PM. Each record consists of one visit and looks like this:
3/1/08 6:00
3/8/08 10:00
3/8/08 10:15
3/11/08 8:30
3/11/08 10:00
3/12/08 9:30
3/12/08 4:00
I created a separate formula for each hour of the day, similar to this:
if Hour()=7 then 1 else 0
Then did a SUM to get the results below:
7AM
8AM
9AM
10AM
11AM
12AM
1PM

My question is: HOW DO I GET AN AVERAGE PER HOUR?

Post Author: PatchesPete
CA Forum: Formula
You are correct, but that's not what I need. I guess my request wasn't very clear.I need to know the average by the hour for the first quarter of 2008.The formula I wrote produces an average by hour by the number of days in the range. Example: Using the formula Sum ({@7AM})/29 produces 43 total number of visits between 7 and 8 AM for the month of February, 2008 divided by the number of days in February, which is 29, resulting in 1.5 visits per day in the 7 - 8 AM time slotMy problem is, how do I calculate the number of days in the first quarter (91 days), second quarter (91 days), third quarter (92 days), fourth quarter (92 days) without having to change my query each quarter to reflect the appropriate number of days?Hope that makes things a little clearer."Pete"

BizTalk Architecture using ESB for High Performance for 10000 requests per minute

Hi All,
I need to design an architecture for BizTalk ESB for high performance.
We are expecting 10000 requests per minute at peak time.
There is no much business logic but rather messaging scenarios.
Please suggest.
Regards,
vikingsss

Thanks Johns,
When I said Clone, I meant We will have 2 BizTalk Nodes, Application deployed on Both just to balance the Load using F5 Load balancer.
And Yes I have considered the SQL Clustering, but is my idea regarding this is correct if I say:
One Cluster 1 Node 1 Message Box will sit
On Cluster 2 Node 1 Other BizTalk DB's will sit
In case of failure on Cluster 1 Node 1(Message box) It will failover to Cluster 1 Node 2
In case of any other failure on Cluster 2 Node 1 (Other DB's) it will failover to Cluster 2 Node 2

IS IPHONE 4S LIMITED ON sms usage per hour?

I'm looking at replacing my Motorola Milestone X with an iPhone 4s, providing it can meet my main need: I have a Church ministry whereby I send out text msgs to members for info updates and prayer requests, and there's 115 people in the group....Can the 4s send out more than 100 sms per hour or is it limited like the Android system?
Also, can the 4s access/use my groups setup in gmail???

Thanks for the prompt response...looks like I might as well stick with the Android since iPhone can't access groups and I definitely need access to those pre-determined groups I have set up in gmail.
Thanks & Merry Christmas!!

Requests per minute in idle conditions in EM

Hello Gurus,
We are having an issue where in our Financial Reporting server is going down after throwing an Out of memory error in the logs in Weblogic.
We have been monitoring the Financial Reporting service in the Weblogic console and in the Enterprise Manager to see the performance and have observed the following --
- Initially the Heap free percent in the Financial Reporting server is staying at 70 - 80 percent for some time immediately after the services are started.
- The heap free percent keeps on going down as the time proceeds.
- The heap goes to 0 and ultimately the services goes into shutdown state in weblogic and becomes unaccesible.
We also observed that the Financial Reporting service shows requests per minute to 80 in the env where we are facing this issue, however it is showing as 0 in the other env which are exact replica - http://s15.postimg.org/bt756hvuj/NEW_PROD_FR_in_Enterprise_Manager_Idle_Condition.png
If someone can point us on what we need to check that would be great. as we are not sure as to why the request per minute will be around 80 in idle conditions.
Any help will be highly appreciated.
Thanks,

Hmmm... you can always try to boot up weblogic with more memory. Look at $DOMAIN_HOME/bin/setDomainEnv.cmd (or .sh in unix) and check for MEM_ARGS variable which specifies memory settings. Double the memory requirements and restart weblogic and see what happens.Increasing the memory is not a concern here, but the thing is that it keeps on going down even when our servers are idle.
Also, what is Requests (per minute) as shown in the screenshot and do you know why the Requests (per minute) is showing around 80 even when there is no work going on?
We have other environment which are again idle and the value is 0 there.

Please help, how to send mails faster / send more mails per hour

hello,
in my application i am using mail sender class i have created to send mail to the users to participate in a survey. following is the code for it. i would like to know if there is anything wrong in it coz it takes to much time to send the mails it is taking 2 minustes to send 6 mails i.e 360 mails per hour only.
following is how i instantiate the mail sender class and then generate a http link string dynamically as it is different for all the user.

Lots of variables here....Also my maths says only 180 per hour.... i.e. three a minute.
1) you are using a database to get info from. What is the average response time of the DB server? Looks like you are doing one SQL then reading the result table but does the initial SQL take a while?
2) how much data are you passing on to the SMTP server and how fast/slow is the link to that SMTP server? Work out the absolute max amount of data you can transfer over the link then get your average message size and work out a VERY theoretical Max number of messages a minute. Note that real life might approach 80% of this taking TCP/IP and SMTP overheads into account.
3) What sort of load is the SMTP server under? If it's busy you will be only getting a fraction of whatever bandwidth is available. Depending on its design it may be trying to deliver the first message you sent it while you are still pumping more messages down to it. SMTP servers may limit the number of connections per minute from another machine in order to defeat a denial of service attack. Your code makes a connection per email so this may have relevence here.
4) Raw horsepower always helps. When I write stuff to do things like this there is no nice GUI screen etc. Just basic Java that if it has to will write a log if something goes wrong. Maybe just maybe a counter on STD out to show it is still actually doing something. Keep the number of classes used down to the bare minimum. In the old days we used to spend days paring code to the bone - a skill somewhat lost these days.
Hope this gives you some help in finding the bottleneck.
Cheers,

How much data does the apple maps app use per hour ?

hello,
i would like to know, if somebody could give me a rough number of how much the Apple Maps app uses per hour for navigation ?

Apple's Maps app uses vector graphics, so it doesn't have to download data everytime your view changes, & also has an offline mode...you can download quite a large area over WiFi & then use this cache to navigate.
So, I really wouldn't worry too much about its data usage. Most tests I've read indicate it uses about 80% less data than Google Maps.

12GB per hour of HD footage instead of 29GB?

Hi,
I recently switched over to HD camera (Sony HDR-HC1E). This is a DV tape cam.
Im editing in imovie 6.0.4.
I always back up my files by exporting via imovie "full quality" when i used to do this with SD content i would get a DV file as result, now on HD i get a .mov file.
I used to get a 12GB file for a 60min movie. Now with HD i am getting 29GB per hour.
I hear other people talking about 12GB per hour for HD content.
Can anyone please tell me how this is possible?
I am going through external hard drives at lightning speed!
Thanks
Dave

Hi Dave
There's actually a big difference between a DV stream (whether recorded to tape or file) and a .mov file.
DV or HDV footage is recorded at 25Mbps - megabits per second. This translates to 90000Mb per hour, divide by 8 to convert bits to bytes, and you get 11.2GB/hour. That's constant, whether on the tape or saved as a DV file. Note that DV is pretty compressed.
Now, when iMovie (or any other video conversion program) saves a .mov file, it's no longer a DV stream. It can be any of the codecs (video formats) that your program supports, and there are a wide range of codecs for both SD and HD. These different codecs will use different file sizes depending on their level of compression. (Just like mp3, a compressed audio codec, vs AIFF, an uncompressed codec.)
You can choose to optimize video on import or choose a smaller format on export (large, rather than full size) which will reduce the frame size of your footage, which may be a good solution for you, depending on what you ultimately plan to do with the material. (Edit: actually, not with iMovie 6 - thanks, Karsten Newer versions of iMovie will help you there. )

What setting is 'DVD quality' widescreen - ie about 3gb per hour?

I have videod (isn't that a such a quaint 20th century word for the podcast age?) a conference and I want to archive the footage to store on a DVD for later reediting.
The "full quality" setting is massive, I only have 90 mins, but a 20 min clip takes up over 10Gb
The 'CD-rom quality' is just not not dvd quality.
(I am using iMovie 06 btw, i will move onto 08 when it is finished)
Ideally, I would just burn the whole lot raw with iDVD and import it again if i need to reedit - but (for copyright as opposed to technical reasons i suppose) we can't just put a dvd in the slot and rip it like we can an audio cd in iTunes. I have tried the workarounds - but none of them worked for me.
Anyway, I digress: What setting is 'DVD quality' widescreen - ie about 3gb per hour?

Hi there.
*Keep the quality*
0nce you have compressed data - you can't get the original quality back - so store as full quality as possible - and in several formats so there is always a backup.
Media
data cds don't hold that much - 700mb - so forget about them for quality productions and archiving
dvd-roms hold much more - 4,700mb (you can get dual layer ones that double it)
*'share' settings*
Now, you have 2 options for saving the movie;
1. as a file on a DVD-Rom (a compact .mov or a massive.dv)
2. as a proper playable DVD (iDVD)
If the "full quality" iM setting is too big a file for a dvd-rom (and you will be lucky to get 10 mins of footage in 4.7gb), then you could 'iDVD' it and that way you will get a good quality movie up to nearly 2 hours on a disc disc that can be played on most machines (and could even be ripped back into an editable form using third party software)
Alternatively, save it using 'expert settings' listed above and you will probably get good enough results for a longer film without having to burn it as a playable (but uneditable) dvd.
Bear in mind that unless you are using a pro camera, you may not notice the much difference with the higher settings.
Good luck - seeing your work on the big screen is a blast!

Controlling multiple travel requests per day via schema

Hello,
I am working on Travel Management.
My client wishes that it should not be possible for any employee to raise more than one travel requests per day.
In the schema, the check box- Multiple TRs/Day is not available. I think with the help of this, maybe issue could be resolved.
I am not sure.
Can someone point out what could be missing? What should I do to control this?
Thank you.

I'm on NW AS 7.03 ABAP Stack 731 Level 13, ECC 606 (EHP 6) with SAP_HR 604 Level 81 and EA_HR 607 (HR-Renewal 1) Level 32 over here. Maybe they really removed it... or it's not available for the deviant Public Sector ;-/. Doesn't really matter though, we don't need it, I was just curious ;-)
Anyway, since this is not your problem (I misunderstood), there are two possibilities I can think of at the moment:
1. The Trip is still in the future, hence the Schema doesn't have to be changed and the system remains in technical Schema PL (which is unlikely in your case if the status really says "Trip Completed"). I.e. your Trip is not in the future, is it?
2. Only one of your expense Schemas qualifies for the trip. In that case the system silently defaults to that one and you don't get the option to choose from a list.
Cheers, Lukas

Rows per hour

Dear All,
I have a table with 2 rows and one has varchar type data and the other is the time stamp (04/02/2013 19:44:40).
Now I want to write a query to count number of rows per hour in the table with date ...strcutre is as follows :
ddata varchar2(20)
ddate date with timestamp ;
Require the output as follows :
March 28th 12 AM - 20
March 28th 1 AM - 40
March 28th 2 AM - 40
where March 28th 12 AM is the date with time
and 20 - number of rows in that date and in that hour..
Please advise..

ddate date with timestamp ;What is this? DATE and TIMESTAMP are 2 different datatypes.
If ddate is a DATE, then it is not a TIMESTAMP.
If ddate is a TIMESTAMP, then it is not a DATE.

SELECT    TRUNC (ddate, 'HH')           AS hour
,       COUNT (*)                AS cnt
FROM       table_x
GROUP BY TRUNC (ddate, 'HH')
ORDER BY TRUNC (ddate, 'HH')     -- Or hour
;TRUNC (ddate) will return a DATE, regardless of whether ddate is a DATE or a TIMESTAMP.

How much is a GRC consultant paid per hour?

I know that in USA, for FICO consultants the rate per hour is in the range of 100 -150 dollars per hour. Will a GRC consultant get more than this or less?
There is a qualification called CISA. Is this GRC anyway realted to this?
Is a GRC consultant involved in SOC compliance?What does he exactly do?

More flexibility in limiting requests per second or minute

We've read the docs on limiting the requests-per-second (max-rps), but we would actually like to set the threshold at less than one request per second. For example, we'd like to set the maximum requests to something like once every 5 seconds. But values like 0.2 for max-rps are not accepted. So the question is:
Is there a way to set the maximum frequency of requests to something like once every 5 or 10 seconds?
Is there an add-in that does that or could we create an add-in to do that?
It looks like the server is NOT open source, so we cannot change the current code to address this, but certainly let me know if I'm wrong about that.
In case it's helpful as background, the reason we want a lower threshold is that we only intend to limit access for html or jsp pages (not gif, jpg, js, css, etc.) That's because we don't want users to get half of a page, like the html, but no images or css, which would look like an ugly error. We want them to get the html complete with all the embeded files or get an error page. We're really only trying to block bots, which might make requests every second or slightly less often, and not block any human users. If there are other general suggestions for how to meet our goal, I'd love to hear them.

No, the lowest max limit is 1rps. The request limiting isn't really meant for what you're describing, it is for limiting high request rates. At less than 1/sec such detection would have false positive with real users anyway, so it wouldn't be such a great way of distinguishing users from bots. I'm not sure it would prove very satisfactory.
You could create your own NSAPI plugin (see docs on NSAPI usage) to implement your desired logic. I'd probably look into long term counters instead, but I don't really know the details of the exact problem you're trying to address.
