OracleMaps-how to calculate the appropriate zoom level of localized polygon

Hi,
I am using this select to localize object (polygon):
select avg(x) X, avg(y) Y from
select t.x, t.y from mvdemo.lhc lhc, table(SDO_UTIL.GETVERTICES(SDO_GEOM.SDO_MBR(lhc.geometry))) t where lhc.id= :ID
so I get the center of map I want to use for OraMaps' setCenter(x,y) function
now I want to use setZoomLevel() function but I have to find out the biggest zoom level in which whole polygon is visible (simply said the biggest picture visible on monitor).
what is the best way to calculate it?
my DIV container for OraMaps has size: width=1000pixels, height=700pixels
my scale range for MapViewer Cache server is 1000 - 5 000 000
and I have 10 zoom levels
thanks,
Branislav

Hi Branislav,
I think, you will find answer to your question in this thread: Re: Zoom To Box

How to see the current zoom level?

I know how to increase or decrease the zoom level of a page. However, Firefox does not show me anywhere what the current zoom level is. Why? Both IE and Chrome show you the current zoom level. I don't want to install any extensions.

If you don't want to install any extensions, then I think at best you might take a look at toolkit.zoomManager.zoomValues preference (in about:config). It gives you information about available zoom levels, but you have to remember how many times zoom in/zoom out actions were used (i.e. there is no current zoom level indicator like in e.g. Opera). For example .3,.5,.67,.8,.9,1,1.1,1.2,1.33,1.5,1.7,2,2.4,3 means that you have:
Levels down (five):
'''30%''' 50% 67% 80% 90%
Levels up (eight):
110% 120% 133% 150% 170% 200% 240% '''300%'''

How to calculate the disk failure level for a 3-way mirror pool?

On another post in this forum, the following information regarding a 3-way mirroring storage pool is given:
Pool requires a quorum of 50% plus drives to be present to survive.
with 3 way mirror - we have a guarantee of surviving 2 disk failure.
Maintaining the above requirements and providing the guarantee -
mandates us to have minimum 5 disks in pool. As if we loose 2, we still
have 3 in the pool (>50%) for pool to maintain it's quorum.
Just to be sure, I would like Microsoft to confirm that the following calculation applies to any number of disks in a 3-way mirroring pool.
If the number of disks in a 3-way mirroring pool is n, INT(n/2) disks can fail without data loss.
Examples:
With 5 disks, INT(5/2)=INT(2.5)=2 disks can fail.
With 6 disks, INT(6/2)=INT(3)=3 disks can fail.
With 9 disks, INT(9/2)=INT(4.5)=4 disks can fail.
Am I right in this assumption?
Thanks for your answer.

Hi,
>>Am I right in this assumption?
Based on my understanding, it’s not this case.
Mirror spaces are designed for increased performance and protect your files from drive failure by keeping more than one copy. Two-way mirror spaces make two copies of your
files and can tolerate one drive failure, while three-way mirror spaces can tolerate two drive failures.
Regarding this point, the following thread can be referred to for better understanding.

Hi, how can I keep the same zoom level for all the pages I view in Safari and even when I close and open it. Indeed with a 27 inch Imac I have a lot of space, most of the websites are built for smaller resolutions and my sight is dropping !   Thx

How to calculate the RMS level of a signal with its spectral representation

hi!
how to calculate the RMS level of a signal with its spectral representation
thanks

1. Find the length, N, of the spectral signal.
2. Convolve the magnitude of the signal with itself.
3. Take the Nth element of the resulting signal
4. Take the square root.
5. This should be the RMS value of your signal.

How to calculate the quota base quantity in quota arrangement?

Hi all,
As we all know, when a new supplier is added in the quota arrangment, we take the help of quota base qunatity so that the new supplier does not get any unfair advantage over the existing suppliers. Would you please help me on how to calculate the quota base quantity or on what basis the quota base quantity is calculated?*
Regards,
Ranjan

Dear,
Quota arrangement divides the total requirements generated over a period of time among the sources of supplied by assigning a quota.
Quota u2013 quota is equal to a number and its represents the proportionate of requirements. Total quota of all the vendors is equal to 100% of requirements.
This quota arrangement is also specific to material and plant level.
Quota rating = quota allocate quantity + quota base quantity / quota.
Quota based quantity used only when a new vendor introduced.
In the as on date situation, the minimum quota ratings will considered as preferred vendor.
The 2 vendors has 2 same quota rating, the vendor who is having the highest quota will considered first.
In the running quota, a new source of supply is included. (In situation of short supply) including a new source not means to reduce the quota for existing.

Syed Hussain.

How to calculate the unit for RATE?

Hey All,
I am not sure if there is something standard for this or not.
I am calculating the 'Rate' by using 'Value/Amount' and 'Quantity' as follows -
Rate == Value / Quantity
I need to calculate the unit for the rate as below -
Rate unit == Value unit (Currency) / Quantity unit (Base_uom)
(for example -
if value is 1000 USD and quantity is 10 TO then Rate should come out as 100 USD / TO)
Could anyone please suggest how to calculate the unit in this case?
Many Thanks!

How to calculate the Current APC (Acquisition and Production Cost)

Hi,
Please help me how to calculate the Current APC.
The Current APC (Acquisition and Production Cost) is a calculated value based on Previous Year Acquisition balance plus any value changes up to the time of the report.
The Asset History Report (RAGITT_ALV01) calculates the Current APC value &
The Current APC can also be found in the Asset Explorer (transaction code AW01N) under Country Book 10/ Posted Values tab then the line Acquisition Value and column Posted values.
I suppose that the calculation of Current APC (Acquisition and Production Cost) is getting done in the GET statements in the report RAGITT_ALV01, but unable to find the actual logic.
Please help me.
Thanks in advance,

How to calculate the Daily Call Volume

Hello,
Can anyone please advise how to calculate the daily call volume in a contact center - the counts of the calls terminated in ICM ?
Is there any webview report or a SQL query which provides the count ?
Many thanks in advance for the help!
Thanks & Regards,
Naresh

The ICM software generates a Termination_Call_Detail record for each call that arrives at the peripheral. From This report you can get the number of calls to ICM as well as the call details.
To get the report run this sql query
select * from dbo.t_Termination_Call_Detail where convert (varchar(10), DateTime, 101) = '12/03/2010'

How to calculate the variance in PO price history?

hi
i hav standard report ME1P, since i need to do some modifications in this program i copied to Y prgrm,,,'
im getting all the values properly...
but my prblm is im not getting how to calculate the variance? im not getting the logic behid it...
can anybody expln me in breif plz....
Regards
Smitha

Hi Venu,
there is another way as well, however, you won't be able to see Variance and Variance% as a saperate keyfigure which is not under the period. Thats the reason I didn't mention it earlier.
What you can do is, Drag the period to the columns, Now create a structure that has the two keyfigures std price, moving price. Here if you add Variance and Variance%, Then these CKF's would come under period as well, which you don't need. And the system won't allow you to add these CKF's outside this structure. The reason being because the interpretation of the data then wouldn't make any sense here. You can create a new structure as well with these CKF's but they would become a subpart of your previous structure.
choose the required characteristics in the Rows section. Save it.
Let us know, Sorry man, can't help u much at this problem.

Sree.

group by
     yr, mnth, region
order by
     yr, mnth, region;I wouldn't recommend storing your data for year / month in 2 columns like that unless you have a really good reason. I would store it as a date column and add a check constraint to ensure that the date is always the first of the month, then format it out as you wish to the client.

How to calculate the number of sent/received emails of a certain domain

Thank you for what you have helped me with!
How to calculate the number of sent/received emails of a certain domain in a certain period? It is Messaging Server 5.2, Directory Server 4.2. Is there a log option for this?
Thank you.

Not sure where you find, "LOG_MESSSAGE_ADD". I don't actually find this option in the documentation.
The domains that mails are coming from and being sent to are certainly logged in the normal mail.log, so why mess with additional logging options? If you're talking about "LOG_CONNECTION", I actually see no additional data that is useful to you.
If you decide to change the option.dat, you do indeed need to
imsimta cnbuild (note, it's not cnrebuild)
imsimta restart
If I were facing the same issue, I'd be looking at the log parsing perl script, and simply modifying it to do what I wanted.
