Case study: "Large?" labview programs flooded with different VIT's

Case study: "Large?" labview programs flooded
with different VIT's
Type of application:
Computer with loads of individual hardware connected or other software (either
onsite (different buses) or offsite (Satelite/GSM/GPRS/radio etc.).
Hardware
description: little data "RPM" but communications to all devices are intact.
More "RPM" when many VITs are involved.
Size: 1000+
VITS in memory (goal). Total software has been tested and simulated with 400.
I'm posting
this post after reading this thread (and actually I cant sleep and am bored as
hell).
Note: I do
not use LVOOP (but sure post OOP examples, am starting to learn more and more
by the day.)
Things I
will discuss are:
Case 1: Memory usage using a plugin
architecture
CASE 2: memory usage using VITs (!)
CASE 3: updating datastructures:
CASE 4: shutdown of the whole system
CASE 5: stability & heath monitoring
CASE 6: Inifiles
CASE 7: When the hardware is getting crappy
Total
application overview:
We have a
main application. This main application is mainly empty as hell, and only holds
a plugin functionality (to register and administer plugins) and holds an
architecture that holds the following items:
Queue state
machine for main application error handling
Queue state
machine for status messages
Queue state
machine for updating virtual variables
Event state
machine for GUI
Some other
stuff
Other
global functionality is:
User
logins, user configurations and unique access levels
Different
nice tools like the good old BootP and other juicy stuff
Supervision
of variables (like the NI tag engine, but here we have our own datastructures)
Generation
of virtual variables (so that the user can configure easy mathematical
functions and combining existing tags)
Licensing
of plugins (hell we free-lance programmers need some money to don't we?)
Handles
all communication between plugins themselves, or directly to a plugin or vice
versus.
And now we don't
talk about that (or marketing) the main application .

CASE 3: updating datastructures:
As we do NOT use clusters here (that would
just be consuming) we only use an 1D array of data that needs to be updated in
different functional globals. If the the number of VITS exceeds so that the
updating of this datastructures becomes the bottleneck, this would cause
delays. And since in this example we use 250 serial interfaces (lol) we do not
want to disrupt that by any delays. When this happends, does anyone know a good
solution to transfer data?
A thought:
perhaps sending it down to the plugin and let the plugin handle it, this should
save some time, but then again if more VITs are added again this would become a
bottleneck and the queue would fill up after a while unable to process it fast
enough. Any opinions?
CASE 4: shutdown of the whole system
Lets say we
want to close it all down, but the VITs need perhaps to do some shutdown
procedure towards the hardware, that can be heavy.
If we ask
them to shutdown all together we can use an natofier or userevent to do this
job. Well, what happends next is that the CPU will jump to the roof, and well
that can only cause dataloss and trouble. The solution here was to let the
plugin shut them all down one by one, when one has been shutdown, begin at the
next. Pro; CPU will not jump to the moon. Con's: shutdown is going to take a
while. Be ready with a cup of coffee.
Also we
want the main application not to exit before we exit. The solution above solved
this as the plugin knows when all have been shut down, and can then shut itself
down. When all plugins are shutdown - the application ends.
Another
solution is to use rendovous (arg cant spell it) and only shut the system down
when all rendezvous have met.
CASE 5: stability & heath monitoring
This IS
using a lot of memory. How to get it down. And has anyone experienced any
difficulties with labview using A LOT of memory? I want to know if something
gets corrupt. The VITs send out error information in case, but what if
something weird happens, how can I surveillance all the VIT's in memory to know
one is malfunctioning in an effective way/code (as backup
solution so the application knows
something is wrong?
CASE 6: Inifiles
Well, we
all like them. Even if XML is perhaps more fahionally. Now Ive runned some
tests on large inifiles. And the labview Inifile functions use ages to parsing
all this information. Perhaps an own file structure in binary format or
something would be better? (and rather create an configuration program)?
CASE 7: When the hardware is getting crappy:
Now what if
the system is hitting the limit and gradually exceeds the hardware req. of the
software. What to do then (thinking mostly of memory usage)? Needing to install
it on more servers or something and splitting configurations? Is that the best
way to solve this? Any opinions?
Wow. Time for a coffee cup. Impressive if someone
actually read all of this. My goal is to reach the 1000 VIT mark.. someday.. so
any opinions, and just ask if something unclear or other stuff, Im open for all
stuff, since I see the software will hit a memory barrier someday if I want to
reach that 1000 mark hehe

Case Study: Caribbean Resort Achieves New Horizons with ProCloud Wi-Fi

The Blue Horizon Garden Resort is located on the southwest coast of Grenada in the Caribbean and sits on more than six acres. For many years the resort has provided Wi-Fi service to its guests, visitors and staff, but the resort wanted to ensure it could provide the highest-quality wireless experience and seamless scale to meet growing bandwidth demands.To meet its bandwidth goals, the resort’s legacy wireless network needed an upgrade in order to match modern connectivity expectations. To determine the best wireless solution for its needs, the BHGR worked with Digicel Group, a global mobile telecommunications provider, to pinpoint what elements of the new network were most critical.After evaluating multiple wireless solutions, together they determined that ADTRAN ProCloud Wi-Fi Managed Service was the best fit.

ONS 15454 design question

I have an ONS 15454 with 2 OC192 circuits that terminate into it. One goes to a downstream ONS and another to the upstream.
I need to extend the existing ring to 2 more ONS devices, but I am not sure if it is going to work the way I want it to.
Right now, each VTS24 circuit on the OC192 is associated with a POS interface on the ML1000 cards. So POS1 goes upstream, POS0 downstream (unprotected). The ML1000 is int turn trunked to a 3750 L3 switch that has the bridge groups and layer 3 addressing assigned. This is Ring0
I need to extend this ring, so obviously I will need 2 additional OC192 cards, but do these new circuits need to be associated with new POS interfaces? In other words, will I need 2 additional ML1000 cards, and if so, how would I trunk to the switch? Am I going to get into some loopy topology here?
I am new to this system, so any advice would be great.

Hi Colin,
so you want to add two more ONS devices in an existing ring.
if you can provide a topology it will be helpful,
if you just want to add two more ONS in existing ring, it will no cause any issues,
we just have to take care of circuits and need to build them from TL1 in these new nodes.
but please send topology to get an clear view.

Does ONS 15454 SDH supports TACACS+ ?

Hi,
We are currently managing 16 ONS nodes in our customer environment and we need to implement AAA using TACACS+ to those ONS chasis.
We are currently using default Superuser account, and we could only find support document related to RADIUS but not for TACACS+.
Does anyone have implemented authendication on ONS15454 SDH with TACACS+ and do let me know how to implement it ? If not, does we have any Cisco document to clarify why it is not supported ?
Thanga

Thanga,
AAA is not supported but RADIUS is. Use DLP-A456 (Configure the Node for TADIUS Authentication) to set up the ONS 15454 to use Radius. It is in the Procedure Guide for the ONS 15454.
If you have any problems please call 800-553-2447 to open a TAC case.

10G Bigger Pipe on ONS 15454

I have two STM4 SDH capacities and one STM16 SDH spanning two cities over different service providers. See Attachment, I have two Cisco ONS 15454 in two cities, one of the ONS is connected to a GSR router serving as core router while the second ONS is connected to a 7609-S serving as MPLS-PE router, their is DOT1q tagging transparently carried over the SDH circuits between the two routers. I want to make these capacities one big Ethernet pipe (10G) at both ends, this fat pipe should be able to carry multiple VLANs between the attached routers at both ends. Is this achievable? if yes what kind of Ethernet cards do I require on ONS and the routers? Any supporting document will be highly appreciated.

"but I am not sure if Cisco produce a 10G ethernet cards for ONS 15454?"
cisco also have 10G Ethernet card but it can go over DWDM box not STM 16 & STM 4.
I am not sure what ECi and Huwai are offering but i am sure of one thing that even if they give you 10G Ethernet card but you CANNOT map that single Ethernet card to your 3 STM interfaces (1 STM 16 & 2 STM 4). As far as i know you can map one ethernet port to one SDH port (either 1 STM 16 or 1 STM 4).
Before believing ECI & Huwaei discuss that solution with some people, as I know one thing there can be lot of strings later on.
They say totally different thing before but once you buy that then you get to know the real features. You will have the feature but with lot of if & but.
What you can do is if that makes sense in your case, take 10 1Gig (Total 10G) ethernet card then you can map 3 ethernet ports to 3 STM interfaces you have.
Whats is the max speed your provider can give you? If they give you 10G SDH then see if you can get 10G POS card for your routers.
You can think of DWDM solution, this way you can take 10G direct over a wavelngth and lot many later. What is the distance between your 2 ONS?

(In this firgure, dont care about side A, my trunk line is cut . The problem is on side B, it pops some minor alarm but the connection is still ok)
ALARM:
You can see that there are: SPANLEN-OUT-OF-RANGE and LOS-O. The problem is the power on line RX on OSC-CSM card is below the configured threshold, right? I have monitored the power and the value is -19.5 dbm.
Then I go to Provisioning --> WDM-ANS --> side B --> Rx --> Threshold.OSC LOS is imported as -23.5 dbm.
I also checked the span loss, the measured spanloss is 15.2 (resolution 1.5). It is between the Min exp span loss (15) and Max exp span loss (17).
So what is the problem, please help me to clear this alarm. Thank you very much.

You are right. the alarm is shown as the power is below the threshold.
If we have OSC LOS threshold set to -23.5 and the total Rx power is Rx power is about -23.5 (on the 40 km span) then we definitely below the threshold as we need to subtract the payload power from the total to get OSC.
Average loss on a fiber is 0.3dB per km, hence the expected loss on 40km would be around 12dB. I doubt the OS Tx power on the remote end is -11dBm (-23 + 12) so most likely that is the fiber/connector issue.
Swap Line Rx and Tx fibers on both switches on OSC-CSM card to verify if the problem follows the fiber or stay with the cards.

Alex.

Dual Ring Capabilty for ONS 15454 MSTP

Hi!
I am designing a MPLS over DWDM network which consist of one core DWDM ring and several regional DWDM ring using ONS 15454 MSTP. I would like to connect the regional ring to the core ring via P router in this case Cisco 12406GSR. My major concern now is to reduce the number of boxes especially on the DWDM part. Can an ONS box connect to 2 DWDM ring, regional and core directly without using a router in the middle. Apreciate your expert opinions. Thanks.
Rgds
Helme

Core DWDM ring and Regional DWDM ring are built using ROADM cards for full add/drop flexibility. Wavelengths can be engineered to pass between rings by physically patching at the wavelength level. By using the Mesh/Multiring Upgrade card (available today - see data sheet below) you can prepare the network for Degree-N capability, allowing multiple rings to be connected via a single point with dynamic wavelength provisioning across the rings.

ONS 15454 MSTP Client Connection Options

Hi!
Have questions regarding client connection options to ONS 15454 MSTP. FYI, I have experience on ONS 15540 ESPx and I usually connect client to the ONS using transponder like this
ONS 15540 ESPx
Client<->transponder<->OADM<->OADM<->transponder<->client
I am new to ONS 15454 MSTP and from the reference manual I understand that the it can be configured as hub, passive oadm, anti ase etc. My questions is how does the client get connected to each of this configurations
For example, for a passive or amplified nodes the client connections would be like this
ONS 15454 MSTP
client<->transponder<->OADM<->OA<->OA<->OADM<->transponder<->client
What about hub nodes where mux/demux card are used, where does the client connect,I do understand that these cards have to be used in pairs.
As always,appreciate your expert opinions and if you can point me to a web link that would be even better. Many Thanks.

In both cases, the client (assuming it has a non-ITU output) will connect via a transponder or muxponder card. This takes the client signal and converts (with multiplexing in the muxponder case) the client signal into an ITU wavelength.
On the MSTP, the ITU port on the transponder/muxponder is then physically patched into the appropriate port on either ROADM, OADM or Mux/Demux cards.
To directly answer your question, on a hub node equipped with Mux/Demux cards, the Tx from the Transponder is connected to the Mux card, and the Rx connected to the Demux. Likewise, at the node where the wavelength is dropped (eg at an OADM site), there will be an equivalent transpoder connected to the OADM module (Tx and Rx at wavelength xyz).
The transponders/muxponders may be in the same shelf, separate shelves, or you may use a direct ITU connection from devices such as a DWDM GBIC, an SDH DWDM card or 10GE XENPAK from Catalyst 6500.
As long as you have designed the network to take the appropriate interface types into account, you should be fine.

Java EE 5 Tutorial case study source code is AWOL

Upgrade ONS 15454 M12 TCC2P from 9.4.03 to 10.0.11

Hello,
quick question.
I have in my lab one M12 subrack with only-one TCC2P card and I try to prepare software upgrade in customer network.
I read all procedures at: http://www.cisco.com/c/en/us/td/docs/optical/15000r/upgrade/guide/b-454a10-0-1-upgrade.html
My troubles started at point where I can select node where the software must be downloaded. The window is empty.
Target version is "ons15454.DWDM.Lite.K9.R10011.pkg".
Any idea?
Thanks

Hi Emyrsonn,
I hope this ONS 15454 upgrade tool can help you answering all your questions
http://www.cisco.com/web/techdoc/optical/15000r/upgrade/guide/ons-upgrade.html
It seems like you should be able to directly upgrade from 9.1.x to 9.2.2.
Please let me know if you have any comments on that.
Hope it helps!

Organization structure for Case study .... need yr advice

Hi I am in process of preparing an org structure for one of the company.
The company operations is like .
The company has four factories in different locations and have 3 Regional distribution centers (RDC) across india. Each distribution center has 5 branches (Sales Offices), in this way they 15 Sales offices across India.
Most of the materials are procured by factories independently while some materials are centrally procured. Factories produce Finish goods and they are either sale to customer directly ( big regular customers) , or transferred to RDC to cater the requirements of other MID size customers and the other possibility to transfer it to Branches for Retail customers. RDCs also transfer FG to Branches.
All factories , RDC and branches have warehouse facility , however branches have limited warehouse facility as the customers supported by them are very few and generally deliveries are made directly from RDC / Factory.
They also have one R&D department in another location to develop new products and material is generally transferred from factories to R&D department.They also have one project division at the same (R&D) location which handles commissioning of new plants and procurement of capital goods.
Raw Material , Semi finish and FG are transferred between factories and FG material is also transferred between RDCs.
The group also has another Company which produces another line of products. RDCs and Branches of first company also work for second company (which means same RDC can store FG produced by both companies) and also Branches can also have FG material of both companies. Second company doesnt have any specific R&D or capital division and R&D and capital of first company also work for second company.
Inter company transfer between both companies is a regular practice.
> Proposed Org structure
Company Group Company
Company Code First company and Second company
Factory Configurations
For first company
4 Factories will be 4 plants
Factories Structure (Storage locations / warehouses and storage type)
Since factories have different type of material ( like FG , Raw material , WIP ) therefore I am confused what option I should select
1) 3 storage location ( for each plant) and one warehouse, 1 storage type
2) 1 storage location and three warehouses (I think this is not possible in SAP , not sure ?? )
3) 1 storage location , 1 warehouse and 3 storage types
RDC structure
RDCs have full fledged warehouse facility and therefore thinking of making them also as Plant. Every RDC will have 6 Storage locations , 1 for First company RDC itself, 5 for associated branches and I feel each RDC storage locations should be a associated to a separate warehouse also.
( Since both companies produce different set of products therefore they will have different material and hence thinking of handling products of both companies in same plant and same storage location and warehouse , may be two storage type/area can be defined to differentiate material of both companies.)
Branches: Will be storage locations under RDC ..
While making branches as Storage location . I have another question about valuation , since material from Plant and RDC is being transferred to Branches and from there it is distributed to customers therefore the valuation of FG at BRANCH and RDC should be different as transportation cost , packing , unpacking etc cost should get added at Branch level.
Therefore in case I make branch as Storage location , I will miss the valuation part while if I make them as Plant then there will be lot of documents get generated for each movement. Hence not sure for what option I should go.
R&D:
Since R& D department is involved in testing in New Product development and generally material is required to be scrapped after testing therefore thinking of making it as Plant with one storage location and may be here I dont need any warehouse (WM) here.
Project Division
Project division may also be a separate plant with one storage location and NO WAREHOUSE is required to linked with it.
Purchase Organizations
4 purchase organizations for each plant respectively and 1 centralized purchase Org for central procurement.
Your all valuable inputs are welcome .... looking foward to have a best possible configuration for above mentioned case study.
Regards

Phew... long long question
The rule I generally follow is that the org structure should map reality.
Company code - where Balance Sheet and Profit and Loss are prepared at the end of the year. If an entity does not do this, it is not a company code.
Plant
1) Each manufacturing facility is a plant (could be in 1 location or separate).
2) Each separate location is a plant (even if it only stores goods). May be an overkill, but helps when legal requirements change or the location is upgraded.
So in your case, RDC will be a plant (may be more than 1 if necessary). R&D should be a separate plant without warehouse management
Storage location
The only rule I follow is that there should not be any overlap of storage locations. So physically, any area of say 1 square foot should belong to one and only one storage location. Otherwise there is a lot of confusion during physical inventory. So logical locations are a no-no.
I usually use a lot of storage locations.
Don't have a warehouse spanning multiple plants (even though it is allowed).
Purchasing organizations
Have one for each location of purchase. If there is a team sitting in each plant procuring for only that plant, have it as a separate purchasing org (not strictly necessary, but makes authorization simple). For central purchasing, a central purchasing org should do nicely...
Hope this helps,
Lakshman

How to create this case study in oracle

Orient Courier Service is a leading provider of courier services to international/domestic destinations. The service has offices all over the country where it picks up parcels for delivery. When a customer walks in for handing over packets for delivery the clerk at the desk keys in the customer’s name, address, email, hp no,weight (package) as well as the receiver’s name, address, hp no, city and country. All the fields are compulsory except the email address. Amount is also entered and is calculated based on fixed charges which are stored in the database. For example.
City
Charges
Johor Bahru
10/kg
Sydney
30/kg
London
25/kg
Based on the above scenario you have to come up with a physical database with the following.
A stored function to calculate delivery charges given city and weight
Hint (create two parameters city and weight)
A stored procedure to insert records into deliveries table
HINT create stored procedure with parameters for each field in the deliveries table for ex customer address, phone, email and receivers’s address etc
