Force required between two vectors

Hi, just a quick problem. I have two 'players' on a pitch. And need to work out how much force is required to move a ball between the two players. They are both represented as vectors. Any ideas? dot product?
Thanks,

It's the inverse square of the negative square root of the hypotenuse of the opposing vectors inside leg, over the sum of the square of E or A on X such that X is equally distributed amongst all players on the bottom peg.
Obvious!

Rotation between two vectors

Hello,
I am looking for a way for my 3D character to slowly rotate
between two vectors. The rotation vectors is results from the
rotation property of GetWorldTransform().
My first idea was to somehow convert the two vectors into
degrees and with the help with that information then simple use the
rotation()-function.
All help to figure out how to do so, or other suggestions,
would be highly appreciated. Thanks. :)
Thanks!

The interpolate() and interpolateTo() commands accept a
percentage value as the second parameter, so you should be able to
specify what percentage of the interpolation you want, at the
current point in time, as a factor of your time delta.

Find difference between two vectors ?

Hi,
I have two vectors, the first contains:
v1.add("1");
v1.add("2");
the second:
v2.add("1");
Now I want to print out the difference between both.
Does anybody have en idea ?
Regards
Micha

Yep, that should definitely do it. I think the point ssav is trying to make is that to solve this problem we need to know your actual requirements. "the difference between" is too vague. Here are some things to think about:
- Is position important? That is, is a List containing 1 and 2 the same as a List containing 2 and 1 or different?
- If List A contains 1,2,4,5,6 and List B contains 1,2,3,4,5,6 what would you want to see?
- What if List A contains 1,2,3 and List B 1,2,2,3?
- What if List A contains 1,2,3 and Lits B 1,2,and a java.lang.NullPointerException?
You're probably starting to see that this is not as simple as you thought. Come back with more specific requirements and you may get better help.

Requirements about delay and bandwith for using OTV in Nexus 7000 between two data centers separated 25 miles?

We have two Nexus 7000, and I need use them with OTV between two data Centers separated 25 miles, but I don´t know what are the optimal values about bandwidth and delay (ms) for extended VLANs IDs (production and DAG replication) for Microsoft Exchange environment. Can somebody tell me please which are the values required for operate OTV in optimal conditions in this case? We have about 35 000 users that will use that platform of email. Thanks a lot for your comments. Regards.

How Can we force the Hyper-V Replica to use a dedicated network between two hyper-v hosts?

Dear Team,
How can we force Hyper-V Replica to use a dedicated network between two hyper-v hosts?
For live migration, we can choose the desired network in Hyper-V Manager (Use these IP addresses for Live Migration).
I have two 10G adapters teamed together, the virtual switch is created on top as converged network with several vNICs (MangementOS, LiveMigratrion, Backup, etc...)
Each network is set with a specific VLAN to isolate the traffic.
The two Hyper-V hosts are on the same LAN and domain.
Thank you.
Regards,

I have accomplished this by using a DNS pointer specifying an IP address on that dedicated network. That will force traffic done that network.

How do I set Time Machine to alternate between two attached external drives (so that if one fails I will have a separate backup to use)?

Hi Everyone.
Thanks in advance for your help.
Right off the bat let me say I am using Mavericks 10.9.1 on a 2011 Macbook Pro and using all Lacie external hard drives.
I am trying to get Time Machine to alternate between two attached external hard drives, trying to be safe in case one of the backup drives itself fails.
I have both drives set in Time Machine.
From what I gather Time Machine should by default alternate between drives when backing up (I would assume it does one big initial backup on each then subsequent backups are just changes).
But this is not how it seems to be working and I cannot find a straight answer despite much Googling and Foruming
Unfortunately it seems to only be backing up to "External Hard Drive 1".
There have been 4 backups since I set it up, all on "External Hard Drive 1", even though "External Hard Drive 2" is also attached and set in Time Machine.
I manually clicked "Back Up Now" and it started to work on "External Hard Drive 2" (like I want it to) for a minute but it appears to have stopped and gone back to backing up to "External Hard Drive 1".
Am I missing something? Does Time Machine only move on to another disk when the first one runs out of space? Do I have to turn one off in order to force it to back up to the other drive (that would be less convenient of course)?
I am hoping that I am missing something and that it will just alternate between the two. Otherwise it is not the most comforting and thorough backup system as I had hoped when I purchased the additional external hard drive.
I have a 1TB drive and a 500gig partition on another drive, both dedicated to backups (my Macbook HD is 475gig). It will take awhile for each to fill up and who knows what could happen during that time. Having Time Machine alternate between hard drives would be a nice small bit of security if the worst happened.
I realize that there are tons of other options for backing up but I just want to use Time Machine if I can.
Again thank you for your help!

You cannot use Time Machine in that way. I'm not sure where you heard that Time Machine alternates between drives automatically. What you can do is create a mirrored RAID array for the backup. This automatically duplicates whatever is on one drive onto the other drive.
Both drives must be the same size, and prefereably, exactly the same make and model. RAIDs can be configured using OS X's Disk Utility.
RAID Basics
For basic definitions and discussion of what a RAID is and the different types of RAIDs see RAIDs. Additional discussions plus advantages and disadvantages of RAIDs and different RAID arrays see:

Hardware or Software RAID?
RAID Hardware Vs RAID Software - What is your best option?
RAID is a method of combining multiple disk drives into a single entity in order to improve the overall performance and reliability of your system. The different options for combining the disks are referred to as RAID levels. There are several different levels of RAID available depending on the needs of your system. One of the options available to you is whether you should use a Hardware RAID solution or a Software RAID solution.
RAID Hardware is always a disk controller to which you can cable up the disk drives. RAID Software is a set of kernel modules coupled together with management utilities that implement RAID in Software and require no additional hardware.
Pros and cons
Software RAID is more flexible than Hardware RAID. Software RAID is also considerably less expensive. On the other hand, a Software RAID system requires more CPU cycles and power to run well than a comparable Hardware RAID System. Also, because Software RAID operates on a partition by partition basis where a number of individual disk partitions are grouped together as opposed to Hardware RAID systems which generally group together entire disk drives, Software RAID tends be slightly more complicated to run. This is because it has more available configurations and options. An added benefit to the slightly more expensive Hardware RAID solution is that many Hardware RAID systems incorporate features that are specialized for optimizing the performance of your system.

Additional data on relationship between two objects

Hi
We have a requirement to capture additional data on a relationship between two objects. The data to be captured are custom fields that are unique to the relationship between the objects and not specific to either of the objects.
We created a new object type and related it to the position (S)and the job (C) object. In the customising (Personnel Management/Personnel Development/Basic Settings/Maintain Relationships there is an option to set up Additional Data. There are however several restrictions (e.g. the substructure has to be in T77AD). When you set up an existing substructure (e.g. PAD22) and screen (e.g. 3000), it works really well, however we have not been able to get this to read our own substructure and screen (since there is no customer include on HRP1001 and the 'Additional data' button seems to go to MP100100 to find the screen).
My question is two fold:
a) Is this an allowed customisation (e.g. can we create our own substructure, screen and Query string)? And if so, how does the data get into T77AD (since SAP recommends that data should not be added to this table)? and
b) Is there any documentation on this (thus far I have only received info on how to enhance infotypes which I don't think is relevant???)?
If this can not be maintained is there any other suggestions on how to deal with this scenario?
Any assistance will be appreciated.
Regards
Liezl

Hi everyone
Thanks for everyone who tried to assist us with this. I am happy to report that our in-house guru's have found the answer. So, for anyone who is interested:
In programme MP100100 you have a screen 6000 which is a customer enhancements screen. We set up two in-house function modules for the PBO and PAI with its own screen and added an append structure to PAD31 to add the fields required. In the configuration, we then specified PAD31 as the substructure with screen 6000 and then also specified our own PBO and PAI function modules. The parameters required for screen 6000 is set up within our own customer screens.
Hope this will be helpful to someone - it certainly seemed to open up some doors for us!

Sharing between two accounts on the same Windows Vista PC

Is it possible to home share between two different accounts on the same computer?
On my son's account, iTunes for some reason won't connect to the iTunes Store. So I would like to enable him to purchase stuff on my account and then use home share to access it. We both use the same Apple ID at home.

By accident I came across a solution that may work for you. This works on a Mac but I think it should work in Windows as well.
On the Mac, if I log into a user account and launch iTunes and then use Fast User Switching to log into another account leaving iTunes running in the first account. I can then launch iTunes in the second account and access all the media stored in the first account's iTunes library using Home Sharing.
I believe Windows has the same ability that allows one user to log into their account while another user is already logged in. If so you may be able to do the same thing in Windows. I'm not sure what happens in Windows to running application when the second user logs in though. If applications are allowed to continue running then I don't see why this shouldn't work in Windows as well. If applications are paused then I can see this not working. The key here to to not log out of the first account therby forcing the applications to stop running.
The downside is that your son would first have to log into your account and launch iTunes before logging into his own account. If giving your son access to your account password is not ideal you could also create a third computer account that both of you have access to that would be used only to store and buy iTunes content. That account could be used as the sharing account that you both can have access to while logged into your own respective accounts.

Configuring SMTP Namespace Sharing between two Exchange Forests on the same LAN

Hi guys, really hoping that someone can help me with configuring SMTP Namespace Sharing between two Exchange Forests on the same LAN.
Basically, I have created a new forest and installed a new exchange organisation in this forest. Both forests are located on the same IP subnet and a two way trust has been created between the forests. Federated sharing has also been configured.
I can use ADMT to migrate the user and computer accounts to the new forest and also migrate test mailboxes over. Ideally, I want to be able to do the mailbox migrations in stages so will need to be able to have mail flowing between the two forests.
I have read over the following article (http://ibrahimnore.wordpress.com/2012/09/06/configuring-smtp-namespace-sharing-between-two-exchange-forests-part-2/)
which is good but it's demonstrating over the internet, can anybody advise how this can be achieved on the local LAN?
Any help greatly appreciated :-)

Hi Gilliano,
Thanks for correct link. I must say this is a very good article indeed, I read the entire article and if you go to the 3rd part of this article, please note the text "DOMAINC.COM is configured as Internal Relay Accepted Domain on both the domains"
This is exactly what I asked you to check. Personally, I understand the method described in this article will work but its very complex to manage and administer, while the easiest option is to configure internal relay at the first place and no need to make
so many DNS changes and customizations to your environment.
The solution really depends on what your requirement is - Since you mentioned that you are migrating stuff over from source to destination - I feel this article is too complex for your situation and not really worth (for your requirement). The setup described
in the article is an excellent choice if you are planning to keep both forests alive for longer duration due to several reasons like compliance or company mergers and so on...
please let me know if my explanation is not clear enough.. we can even even have a one-on-one email conversation too!
All the best!
Please mark as helpful if you find my contribution useful or as an answer if it does answer your question. Regards, Siva

OBIEE 11G - Issue passing parameters between two reports

Hi folks,
I am struggling to pass parameters between two reports in OBIEE 11G.
My first report contains the following columns: Rolling Year Type (VCHAR), Year(VCHAR), Month(VCHAR), Cost(Double).
My second report contains the following columns: Rolling Year Type(VCHAR), Year(VCHAR), Month(VCHAR), Category(VCHAR), Cost(Double).
My requirement is to pass the Rolling Year Type, Year and Month values from report 1 to report 2.
On the Month column properties of report 1, I have created an Action Link called 'Drill to Category'. I have clicked on 'Navigate to BI Content' and selected Report 2.
Then on Report 2, I have included three filters: Rolling Year Type is prompted, Year is prompted, Month is promted.
When I run the report I always get the following error:
The specified criteria didn't result in any data. This is often caused by applying filters and/or selections that are too restrictive or that contain incorrect values. Please check your Analysis Filters and try again. The filters currently being applied are shown below.
When I check the cursor cache, the filter values are correct. Does anybody have any idea why Report 2 does not display?
When I remove the Month filter, the report works correctly.
I have since changed the third filter to be Month No and although Report 2 does display, it does not pick up the filter on the Month No.
I initially thought this may have been a caching issue and so I have disabled BI Server Cache but this does not fix my problem.
This was never an issue on OBIEE 10G as I found it very easy to navigate between two requests.
Has anyone else experienced problems with passing parameters between two request in 11G?
Any help appreciated.
Thanks
Gavin

Hi,
I once tried this kind of requirement(with dashboard prompts though) and hit at similar issue. I later found out that the problem is with the space in the parameter values. Can you please let me know, if the same is the case with you?
Suppose the parameter passed is "Jan 2010", but the report on the destination takes the value as "Jan" & "2010". Yes, it kind of split the parameter value to two based on space. I think we can notice the filters the destination report got, by enabling filter view.
In this case, since you pass only value at a time, could you try placing the parameter value anyway in double quotes? I think the Server then will understand it as one value.
Thank you,
Dhar

Add new row in table between two rows - OATableBean

Hi,
I have a requirement where I need to add a new row between two rows. Lets say I have a table with 5 rows. I am envisioning having an icon (table switcher) on the row #1, which when clicked will insert/create a new row between rows #1 and #2 like #1.5, something that can be achieved in core forms. In core forms, when we click the add button, it immediately creates a new row before the current row ( and pushes other rows down). Is that possible with OATableBean. Please let me know if you have any ideas.
Thanks,
Ravi.

Hi,
I used following code to insert the row in the end
public void createNewRow()
XXEGASRLinesVOImpl vo =getXXEGASRLinesVO1();
Row row1 ;
int i;
Row row[] = vo.getAllRowsInRange();
row1 = vo.createRow(); //vo.createRowSet("10");
vo.insertRowAtRangeIndex(row.length,row1);//.insertRow();
row1.setNewRowState(Row.STATUS_INITIALIZED);
Check if it works for you, you have to modify it to meet your requirement.

Swap between two different item categories in sales orders for sub-contracting

Dear gurus,
my requirement is to have the ability to swap between two different item categories for sales orders for sub-contracting.
This should be controlled by a combination of the material and a value maintained the Usage field in the Customer Material Info Record (for example by entering a ‘V’). A combination of Sales Doc Type, Item Cat Group and Usage should result in the creation of a purchase requisition.
In the event that a process order is required instead of a purchase requisition (i.e. the product is to be manufactured in-house instead of sub-contracted) the user must have the ability to change the Item Category within the sales order to produce a process order.
The user would just change the item category within the sales order, and the system would automatically remove the purchase requisition assigned to the SO, and create a process order and assign it to the SO.
Can you suggest any possible solution?
Thank you in advance.

Hi Majlo,
In my system, I checked. First created sales order with third party line item and then changed item category to normal item category.
Till Purchase order not created, I can change Item category of my sales order line item.
In this case SAP inform by log and once save delete purchase requisition of that line item .
For this you need to assign another item category as an manual item category in SPRO Item category assignment.
After this user can manually change item category to other one manually, if PO do not exist.
Please let me know if your query is different.
Regards

Automatic creation of transportation lane between two Plants or location

Hi,
I am aware that when we cif Inforecords from R/3 to APO new transportation lanes automatically gets created between the Plant and Vendor.
The isssue which i am facing is that i want transportation lanes to be created between two plants . The TL should be created automatically. I could find the below details from sap help.
http://help.sap.com/saphelp_scm41/helpdata/EN/3e/dfaf376ed96c21e10000009b38f8cf/frameset.htm
Transportation Lanes with Reference to R/3 Material Master Record
Storing a special procurement type with procurement type F: External Procurement and special procurement U: Stock Transfer (in the MRP 2 view of the R/3 material master record), means that the material has to be procured externally from another plant (supplying plant) or transferred from another plant.
To also be able to perform stock transfers for this material in the SAP APO system, there has to be a transportation lane from the supplying plant to the receiving plant. If you have transferred a material with this special procurement type from the SAP R/3 system, the SAP APO system automatically creates a corresponding transportation lane from the supplying plant to the receiving plant for the supplying plant (from the special procurement type) and material/plant combination. The transportation lane is given the creation indicator u201CSu201D for special procurement.
I am not able to make sense of special procurement U: Stock Transfer (in the MRP 2 view of the R/3 material master record),
Is this Special procurement some sort of customization as i could not find U: Stock Transfer in my implementation.
Please help me understand this. What exactly should i do to create TL between Plants automaticcaly through Cif.

You need to define setting in IMG for this from source to Target location.
Follow this path :
Production->Material Requirements ->Master Data->Define Special Procurement Type
example :
Plant      1004
SP type    40   Stock transfer (proc.from alter.plant)
Procurement type     F    External procurement
Special procurement U    Stock transfer
Plant                1039

How do I share iPhoto libraries between two Macs?

Hi! I would ideally like to have one iPhoto library to share between two different Mac laptops. Is there some way I can set it up so that the same library can be shared, edited, and updated? Or if not, is there a way I can see the other Mac's iPhoto library? Both computers share the same Wifi and both using Mountain Lion OS (but I can upgrade if that would help).
Thanks!

The only way to do what you want is to put the Library on an external disk formatted Mac OS Extended (Journaled). Then connect - a wired usb/firewire/thunderbird connection - the drive to each machine as required.
What you're describing is a media server. They start at the $200 mark.

Need to know how to calculate and allocate the server side bandwidth between two exchange sites for DAG replication

Hi All,
Please have a look in to the below mentioned environment.
primary site :SITE 1
server 1
server 2
secondary site :SITE 2
server 3
Note : All the above three servers are in single DAG .All the database are mounted on the server (server 1) which is located in the primary site (I.E SITE 1).
On that 5 databases we are having 3500 users .Based on the user designation we have allocated the mailbox size.
Query : Each and every day we are having the large no copy queue length for all the five databases to the server located in SITE 2.
Please help me out on this and also tell me is there any tool available to exactly get the required bandwidth for the exchange servers located between the active directory sites.
Thanks & Regards S.Nithyanandham

I don't know of any tool that can calculate things for you but latency is the biggest thing you have to worry about. The other issues is looking at the network gear between the 2 sites. I have seen many times were switches get maxed out if they are set to
1 GB or even ports getting maxed out and need to bonded for more throughput. Test your latency from the edge of each site then test it within to see if there is a difference.
Regardless of their geographic location relative to other DAG members, each member of the DAG must have round trip network latency no greater than 500 milliseconds between each other member.
As the round trip latency between two Mailbox servers hosting copies of a database increases, the potential for replication not being up to date also increases. Regardless of the latency of the solution, customers should validate that the networks between
all DAG members is capable of satisfying the data protection and availability goals of the deployment. Configurations with higher latency values may require special tuning of DAG, replication, and network parameters, such as increasing the number of databases
or decreasing the number of mailboxes per database, to achieve the desired goals.
Round trip latency requirements may not be the most stringent network bandwidth and latency requirement for a multi-datacenter configuration. You must evaluate the total network load, which
includes client access, Active Directory, transport, continuous replication, and other application traffic, to determine the necessary network requirements for your environment.
