BGP PROCESSES AND ICMP TREATMENT

Hi everybody
I hope you guys are doing fine.
http://www.cisco.com/c/en/us/support/do
cs/ip/border-gateway-protocol-bgp/107615-highcpu-bgp.html#understandbgp
From the above link:
While BGP scanner runs, low priority processes need to wait a longer time to access the CPU. One low priority process controls Internet Control Message Protocol (ICMP) packets such as pings. Packets destined to or originated from the router may experience higher than expected latency since the ICMP process must wait behind BGP scanner. The cycle is that BGP scanner runs for some time and suspends itself, and then ICMP runs. In contrast, pings sent through a router should be switched via Cisco Express Forwarding (CEF) and should not experience any additional latency.
1)Are we saying the pings sourced from the router will be switched using CEF above? Just want to confirm that.
Please consider the following example:
CE----------R1-----ISP CORE---
Above CE is customer router connected to R1 for internet connectivity. R1 carries Internet routes in a service provider network
So If we issue pings sourced from R1 to CE, will this pings be CEF switched? will the ping replies from CE destined to R1,given lowest ICMP priority, even though CE is responding to R1 pings?
Thanks

Hello Sarah,
I hope you are well
ICMP packets originated by the router or destinated to the router are processed by main cpu not by CEF, they are actually placed in an internal queue waiting to be process switched by the main cpu and this may expose them to some delay as explained in the link about BGP scanner. (this is called punting to the main cpu the packets are punted). The same happens for protocol messsages.
The reason is that the packet needs to be examined to prepare the appropriate answer.
So going to your example, the CE node will process switch the ICMP echo request coming from R1 and will process switch the ICMP echo reply to R1, the same happens for R1, that has a full internet table, it process switches its own requests and CE's replies.
So it is R1 the more likely device to introduce delay variation.
in other words the RTT of ICMP packets may vary depending on when they are issued.
Traffic going through the router is CEF switched and far less impacted by BGP scan process.
Hope to help

SCNARIO AND FI TREATMENT

I have scenario here that, if we request some material for our 4 offices which are attached to one plant how i can differentiate the qty and how we can come to know that where this material has received and it value too and FI treatment and when invoice recieved what will be the treatment.
As per my understanding while purchasing we have to give plant for which plant we are going to purchase and when we do GR then we are going to give the location mean office location where we are going to received the material hence in the same way we can see its value and qty but value will be valuated at plant level, if anything else pls inform to me and if u can elaborate about FI in this scenario I will appreciate it.
Regards

Hi,
As per your question and answer both, the solution sounds good and this will provide you details of quantity received in each office (Storage Location) but Stock will get valuated at Plant level not Storage Location level. (This solution is good and simple to track if client doesn't want to track the stock value at each office i.e. Storage Location and to get GR Value not Stock Value you can refer Report MB51 as per Storage Locations)
But if you are interested to get stock value also at office level then you have to use concept of Split Valuation
I will explain this with an example, For e.g. valuation criteria is ORIGIN
Go to OMWC - Configure Split Valuation
Here Create Valuation Category as for e.g. "ORIGIN" and Valuation Types as "DOMESTIC" and "IMPORTED"
Here in Valuation types, you can assign the Account Category Reference
And in OMSK - You can define 2 Valuation classes and assign these to 2 Account Category References
Now in OBYC - Maintain Account Determination for Account Key BSX as per the valuation class
Refer following link for detailed configuration of Split Valuation
[Split Valuation Process|http://www.sap123.com/showthread.php?t=29]
[Split Valuation Help|http://help.sap.com/saphelp_erp60_sp/helpdata/en/8f/d1de34e4cb2300e10000009b38f83b/frameset.htm]
Process Flow: -
1. Create Material Master for Asset in MM01, maintain valuation category ORIGIN in "Accounting 1" view and extend the material master for all the above 2 valuation types and input the value.
Here in your case Valuation Types will be "DOMESTIC" and "IMPORTED" and also assign the respective valuation classes.
When you want to Purchase materials then,
1. ME21N - Create for Material with valuation type "DOMESTIC" or "IMPORTED" as per requirement, maintain it in "Delivery" Tab
2. MIGO - GR w.r.t. PO (GR of material will be done in valuation type as per maintained in PO "DOMESTIC" and "IMPORTED"
3. MMBE - Stock Overview (Here you can see the stock as per valuation type "DOMESTIC" and "IMPORTED"

When I plug in my iPhone to sync, it starts but does not complete the process and several pieces of data are not being transferred to my iPhone from my MacBook Air.

Problem:
When I plug in my iPhone to sync, it starts but does not complete the process and several pieces of data are not being transferred to my iPhone from my MacBook Air.
Any help that you can provide in helping my iPhone accurately sync with iPhoto and iTunes will be greatly appreciated.
Symptoms:
1)   Sync: It’s not completing the sync. Below, I’ve provided all of my settings from the iTunes Summary tab so that you might tell me if I’ve selected any incorrect options. I prefer to sync the “old school” way – by connecting to the computer – as opposed to syncing over the cloud. Perhaps this is what’s causing the problem? Here is a list of the steps displayed in the iTunes window as the sync progresses:
waiting for sync to start (step 1 of 7)
backing up (step 2 of 7)
preparing to sync (step 3 of 7)
determining apps to sync (step 4 of 7)
preparing apps to sync (step 5 of 7)
importing photos (step 6 of 7)
waiting for changes to be applied (step 7 of 7)
syncing apps / copying 1 of 4 (App name) (step 7 of 7)
canceling sync
apple icon
2)   Photos: I've selected only certain of my iPhoto albums to sync to my iPhone. All of the albums are correct/complete in iPhoto. All of the albums are listed on my iPhone, both before and after the sync, but the albums are empty (no actual photos) before and after the sync. Perhaps this is tied to the fact that the sync isn’t completing, but because “importing photos” is one of the steps that the incomplete sync displays, I don’t know.
3)   Apps: When I launch iTunes and click on the Apps folder under the Library listing, then click on the Updates tab, iTunes searches for any Apps needing to be updated and provides a list. If I click on Update All, the Apps are successfully updated in iTunes. But, when I plug in my iPhone so that the updates will transfer to the apps on my iPhone, the updates don’t transfer to the apps on my iPhone and those apps still reflect that they need updating on the iPhone.
Other Potential Pertinent Info:
The flash memory hard drive on my MacBook Air recently died (perhaps a month or two ago). Apple had emailed me about a known issue and literally the next day, my MacBook Air crashed. I installed a new flash memory drive and re-installed everything from a backup off of an external hard drive. Everything seems to be working fine; it recreated accurately all of my software and data, including iPhoto and iTunes, the pictures and songs (respectively) for which are stored on that hard drive, as opposed to being on the flash memory in the MacBook Air itself. However, I don’t recall if the start of the sync problem described herein started happening at the same time that I replaced the flash memory drive. All I know is that the computer is working perfectly in all respects and that even as the sync is failing, it at least says that it’s doing the right things and looking in the right places (e.g., the list of albums on my iPhone matches the list of albums in iTunes, etc.).
Settings/Status:
MacBook Air
OSX v. 10.9
iPhoto ’11 v. 9.5 (902.7)
iPhone iOS 7.0.4
iTunes v. 11.1.3 (8)
Summary Tab
Backups (This Computer)
Options
Automatically sync when this iPhone is connected
Sync only checked songs and videos
Photos Tab
Sync Photos from iPhoto (429 Photos)
Selected albums, Events, and Faces, and automatically include (no Events)
Albums – 9 are selected

You need to download iTunes on your computer. iOS 6 requires the latest version of iTunes which is 10.7.

Third Party Process and Inventory

We are using the SAP function "Third-Party Processing". We are using the function in it's standard (SAP R/3 4.7).
The auditor now has the following issue: Shipping the goods starts after paying the goods. Out of this, while shipping the goods, we are the owner of them. In this circumstance the ship is our warehouse.
SAP does not allow an Inventory Management within Third-Party Processing:
"Since a third-party order involves a movement from the vendor direct to the customer, Inventory Management is not in any way affected. If you wish to document the movement in the system, however, you can create a goods receipt for the third-party order."
With the SAP functions in this scenario it is correct that the warehouse stock is not being impacted. This is a conflict with the opinion of the auditor.
Let me explain in detail what is wrong out of the view of our auditor:
For example we initiated the order of a customer in June and we have paid the goods in June. The shipment starts in June and the goods will arive in July. Due to the fact, that we are the owner of the goods on the ship, we have to increase the stock. This is the opinion of our auditor.
Does any body know, how to solve the issue? How do you manage Third Party Processing & Inventory?

Some auditors just dont understand the SAP process. Instead of talking to weak users, they should talk to SAP directly.
What about shipments from standard sales orders that are shipped end of June and do arrive at the customer in July?
When do you bill your customer? when the goods arrives there, or earlier? Depending on the Incoterms you may still be the owner until the truck is unloaded.
If you change your process and post goods receipt to your warehouse, then you show inventory where no physical inventory is, you posted a goods receipt without a physical receipt. I am sure the next auditor will not allow such therotical process.
Get together, IT consultants of FI and MM and SD, strong business people for the same modules and the auditor, and discuss and find an optimal solution.And let the auidor sign the decision paper!!! Very important, I recently had to convice German auditors because they had different opinion than the Australian and US auditors of the same auditing company (and the issue had nothing to do with local legal requirements).

What is the optimum core configuration for a new Mac Pro to process and manipulate very large (80 megapixel) images using PhotoShop and Camera Raw?

Hello:
I will be using creative techniques to process and manipulate a large number (hundreds) of very large (80 megapixel) images captured using a medium format digital back (Phase One IQ180).
Final output will be digital fine art imagery printed using an Epson 11880 at large sizes (up to 60 inches x ?), retaining the highest possible quality and resolution. I will be using Adobe CC PhotoShop and Camera RAW as well as Capture One software. PhotoShop filters will be used extensively.
The Mac Pro needs to be optimized for the above purpose and be useful for at least five years. I plan to max out all the other options (RAM, graphics cards, storage). Performance is more important than cost.
The few discussions I have found that mention optimum core configurations seem to lean toward 6 or 8 (but likely are not taking into consideration my need for manipulating a large number of very large files), so I am looking to this foum for opinions.
Thank you,
Kent

Image Processing and machine vision don't appear in Function Palette

Hi,
I have problem and I can't solve it
Image Processing and machine vision don't appear in Function Palette, Although I set up NI imaq and NI Vision Acquisition Why??
Anyone can help me?
Solved!
Go to Solution.

If the image is already a Grayscale U8 image you would just have to save it to a bitmap file using the IMAQ WriteFile VI. If not, use the IMAQ Cast Image VI to convert it to a Grayscale U8 and then save it.
Also, it would probably be better to create a new thread for questions like these.

Spawned Processes and Memory

Hi Guys,
Does the JVM limit the amount of memory that a process uses when spawning using Runtime.exec()
Basically we are trying to run the microsoft linker from Java (via Maven) and it keeps erroring with 'out of memory' this seems to happen when the process uses around 275MB of RAM.
Are processes spawned by Java limited to the amount of memory allocated to the JVM via -Xmx ?
Any insight on this matter would be appreciated.

Check the source code of the function
Java_java_lang_Win32Process_create
in j2se\src\windows\native\java\lang\Win32Process_md.c (you can get such
source code downloading the SCSL Source code.
The relevant information is posted below.
    si.dwFlags = STARTF_USESTDHANDLES;
    processFlag = CREATE_NO_WINDOW;
    ret = CreateProcess(0,                /* executable name */
                        cmd,              /* command line */
                        0,                /* process security attribute */
                        0,                /* thread security attribute */
                        TRUE,             /* inherits system handles */
                        processFlag,      /* selected based on exe type */
                        envcmd,           /* environment block */
                        cwd,              /* change to the new current directory */
                        &si,              /* (in) startup information */
                        &pi);             /* (out) process information */It simply does not adjust memory size, or do something mysterious. It simply creates the process, and redirects the input , output and error streams.
You really must get more memory (or adjust the size of your Windows swap file)...
You can try lowering (not raising) the -Xmx limit of your Java program to make more room for the "link" process.

I tried to install yosemite yesterday and my computer goes through the whole installation process and then to a blank white screen. I've rebooted, I've reinstalled several times and get the same result. Two days wasted!

I tried to install yosemite yesterday and my computer goes through the whole installation process and then to a blank white screen. I've rebooted, I've reinstalled several times and get the same result. Two days wasted and I can't use my computer!!

I don't know if you've already resolved your problem, but I had the same thing, it took me 6 hours to fix it. I had the exact same as you, installed the update and then it went to a white screen. After trying start up holding down cmmd r or holding down the alt key to try to install it again, nothing worked, same result every time. Then an angel came to me here somewhere but I can't find it now to thank him. Start in safe mode, press shift once you hear the start up chime and hold it down until you hear it again. Installation completion box came up and it was working. turn off computer and start up again normally and all is well. Except my final cut pro x doesn't work with it, have to update that now too. same as when I updated to mavericks.
Hope this helps.

I'm trying to buy a book. The book is made in I-Photo and when I push buy book button it starts to process and than says-- There was a problem communcating wit the apple store " help"

I'm trying to buy a book I made in I-photo. I have made a 20 page book in I-photo and when I push the "buy book" button it starts to process and then pops up a sign that say'es There was a problem commucating with the apple store. Please try again. Help

Are you buying from the correct Print Products Store? If you are using the wrong store, your AppleID may not be valid.
Is the Print Products Store set correctly in iPhoto Preferences > Advanced? It should be set to the same country as your billing address and delivery address, and match the settings of the Apple ID you are using.
And you are using iPhoto '09 or '11, right? you can no longer buy books from earlier versions.
When you reenter your settings as LarryHN described, don't forget to enable Express Checkout. It is required.

Replacement Needed. This iphone is not able to complete the activation process and needs to be replaced. Please visit your nearest apple store or authorized service center.

Probably will never ever think of buying a locked phone from AT&T cause its one of the worst system integrations ever that these companies could think of.
The entire problem started when I put in a request with at&t to unlock my iphone 4s (ios7) which did get approved. I performed the entire instructions they asked me to do, which is to backup and restore. After doing those instructions my iphone gave me an error message below
The SIM card inserted in this iPhone does not appear to be supported.
The SIM card that you currently installed in this iPhone is from a carrier that is not supported under the activation policy that is currently assigned by the activation server. This is not a hardware issue with the iPhone. Please insert another SIM card from a supported carrier or request that this iPhone be unlocked by your carrier. Please contact Apple for more information.
Basically saying that at&t hasn't still unlocked the iphone which a really helpful apple executive was able to confirm. I initiated another unlock process from at&t in order to unlock the iphone, just to be sure that its not something wrong from my end. The nice at&t lady stayed on chat with me to unlock the iphone step my step while I was calling the apple tech too. And the apple tech confirmed again that the iphone is locked to at&t.
Now, just a few minutes ago I tried another restore to see if any progress is being made and to my surprise I got an error message saying
Replacement Needed. This iphone is not able to complete the activation process and needs to be replaced. Please visit your nearest apple store or authorized service center.
I feel like I am just going around these two different "money hogger" companies which set certain rules and regulations to screw a regular phone buyer. I purchased this iphone in USA and trying to unlock in India, is it really this hard to simply unlock a device.
For now I am going to try to call a apple office in india (apprently we don't have very many out here) and see if they can help me. But any other assistance regarding unlocking an iphone 4s would be helpful. I have however, tried checking IMEI.info, called up apple, talked to at&t (which always say go talk to apple) I do have a case number from apple as well in case an apple executive reads this discussion forum (case number: 566383594)
Thanks

You got a confirmation from AT&T that it was authorized. Is this correct? - Yes i did get an email authorization on the 21st.
Then you connected the phone to a computer with the latest version of iTunes installed. You clicked on the phone's name in iTunes, then clicked "Backup Now". - Yes
When that finished you clicked "Restore iPhone" (NOT "Restore Backup") - Yes
Are you with me so far? - Yes.
And @ Varjak is right that after the 3rd restore I get the replacement error.
Plus I have NEVER jailbroken the iPhone. To give you another update, I spoke to a really nice apple tech in India who was atleast able to get me out of the replacement error by doing a recovery mode option. However, the lastest restore still gives me the same error
The SIM card inserted in this iPhone does not appear to be supported.
The SIM card that you currently installed in this iPhone is from a carrier that is not supported under the activation policy that is currently assigned by the activation server. This is not a hardware issue with the iPhone. Please insert another SIM card from a supported carrier or request that this iPhone be unlocked by your carrier.

I attempt to open a second window from the icon but it does not open then when firefox is closed it will not reopen because it is still running in processes but no window displayed until you kill the process and then restart firefox.

I attempted to open a new window from the Firefox icon but nothing happens. I then went on browsing and closed Firefox but was later unable to open it. I checked processes and it was already running but there was no window displayed. I am running Windows 7 Professional.
This is repeated any time I already have the browser open and wish to open a second instance.

I updated to Firefox 4 and ever since it won't open. It says the process is running but no matter how long I wait it won't open the browser and restarting or ending the process and trying again doesn't work either. Is there any way to fix this?

I thought it might be a compatibility issue with Windows Vista but the same problem happened on a computer with Windows 7. I'm not sure if the Windows 7 problem was resolved, though.

You probably have other problems but for a start right click on your task bar and click on Start Task Manager. In "Applications" if Firefox is shown, click on "End Task". In "Processes" if Firefox.exe is shown, click on "End Process" and ignore the warning and click"End Process" again. Wait for a few seconds then start Firefox in the usual way. There is a chance that this may solve your problems.
If not, you probably will need to do a complete uninstall and re-install. If you can't start Firefox you could try starting in Safe Mode - Hold down Shift key as you double click on the Firefox icon>ignore the page that opens>and Continue. If you've been able to open Firefox you could work through this Troubleshooting Procedure -
https://support.mozilla.com/en-US/kb/Troubleshooting%20extensions%20and%20themes
If at any stage you are not making progress, report back here for best advice on an Uninstall/Re-install which is quite likely to be necessary.

Question on App Process and Java script performance

I have quick question regarding performance of Application process and Javascript.
I'm having OnDemand Application process, which fetches data from db and thru javascript
in page, i'm invoking the application process.
My question is :
If I did not render a page say for 10 mins, and i'm changing field values in my tab report.
Consider i'm having a huge record in my tab report and changing certain updatable column value for all records.
Once i finsished updating the field value (before hitting submit). The same field might have been updated by someother user.
If i render the page, Would it shows data as per current session value or data same as 10 mins before?
Bit confused on this.
Your views on this would be highly appreciated!!
Thanks!
Vijay

... one more reason not to use Tabular Forms.
I'm not sure this is related to performance. I think this is more of a lost update question. If you're using a standard Tabular Form, APEX will check the value of that data in the database to see if it's changed since you opened it. If so, it means someone else edited the data then saved it since you opened the page. APEX will return an error. At that point, the user would have to reload the whole page. If you expect collisions and the fields are big enough that it will take a person a long time to edit, I would strongly suggest NOT using Tabular Forms. If you're only editing one row at a time, the chance of collision between you and another users is substantially less than if you were both editing 15 rows at a time. Also, if there is a collision, you only have to reload one record, not a whole set of them.
