How to deal with multiple disk path's

hi
i'm setting up a new server with virtual servers with extra io domain's
now i have a question on how to deal with multiple disk path's
so following questions:
- can i enable multipath on the primary and on the alternate domain?
i tried this but when rebooting the alternate the alternate keep's freezing and the only solution is to hard stop it and it's depending host
- if i can't enable multipathing how to handle this
for example a disk has on the primary domain 4 path's to a disk
do i then assign all 4 path's to a virtual disk server or do i create a virtual disk server per path
if i do the first is adding all the path to the same mpgroup enough or not

Hello
1.-can i enable multipath on the primary and on the alternate domain? Yes. i understand for multipath mpxio or similar.
2.-i tried this but when rebooting the alternate the alternate keep's freezing and the only solution is to hard stop it and it's depending host
if you are going to use alternate domain you have to give this IO the all bus root nexus, what you describe sounds like DIO,
3.- - if i can't enable multipathing how to handle this for example a disk has on the primary domain 4 path's to a disk
If you have 4 path to the same disk in the primary and you are using multipath let's say mpxio, then you will have only one disk in the primary, which is a virtual device that handle the 4 paths. That's is what you have to use in a vds.

How to deal with multiple language SQL script?

Hi All,
We now want to create a SQL script that contains multiple languages(English, Chinese, Japanese), this script need to be run at there different database installed on different OS, for example, Oracle9i on Windows 2000 English Edition/Chinese Edition/Japanese Edition.
If I save the file as ANSI format, this file will only be recognized at local OS(e.g. the Chinese and Japanese character will not be normally displayed on other OS, if I run the script, the CH/JP characters will not be stored normally in DB).
If I save the file as Unicode format, this file can be recognized by all three OS, but Oracle SQL Plus will not recognize it, thus we can't run the script.
Who can tell me how to deal with this issue? Is it possible to save only one script that can run on different language OS?
Thanks,
Spark

Hi,
The ISQLplus supports multiple languages, but there will be following problems for my case:
1.ISQLplus don't support Unicode format script too, so I must save the file as ANSI format.
2.To display the characters normally depends on the database server's platform. I create a script contain three languages with ANSI format in Chinese OS, but if I want to load this script to database server installed on English OS via ISQLplus, the Chinese characters will not be displayed normally too.
PS:
So, I think this is not only related with Oracle but also the Windows OS, it is hard to create one file with ANSI format that can be displayed normally in different platforms.
Thank you all the same,

How to deal with multiple hard drives?

I am using Aperture 1.5 but am having trouble
dealing with the Library structure. I want to be able to have Aperture recognize and work with Projects located on several different external hard drives. Where should the main library be located? In 1.5 is there such a thing anymore as a Branch library? I had a branch library on an external drive. I may have messed things up so that Aperture doesn't quite know where things are. Is there a way to re-organize things so that when I open Aperture ALL the projects I've worked with do appear? Thanks.

To have Aperture work with projects on different hard drives, just import the project files but tell Aperture to copy the files from their current location (say a media card or CD) to a directory of your choice on any drive of your choice. You can store projects on multiple drives. I don't think it matters where the main library is located, it could be on your primary drive, or on one of your external hard drives. I'm not sure how to consolidate projects that were enclosed in different libraries other than to export the projects individually, and then reimport them into the new centralized library. I do wish Aperture would allow one multiple select projects (it only allows you to select one at a time) for exporting. I also wish that Aperture had a 'Consolidate Libraries' command which would allow one to just pull all 'found' projects into one library.

How to deal with multiple mail files?

Here's the story; it's sad but true: After a failed iSync spirited away all of my emails, the Apple Care techie I spoke to a month ago wasn't able to fully resolve the problem. So, currently in my Home Library folder I have 2 Mail files: #1 is labeled "Mail" and #2 is "Mail Copy."
"Mail" has one sub-folder called "Mailboxes" and four other folders for each of my four POP email accounts (there are also a number of other files that I'm ignoring for the moment like--Envelope Index, Signatures.plist, ect.). All mail from the past 4 weeks is in the folder labeled "Mail." But...
The other folder in my home library--"Mail Copy"--contains 3 POP email accounts and each one has sub-folders that contain mailboxes with my emails that go back many months. I want to keep the email in both folders, "Mail" and "Mail Copy."
Problem: How to get the older messages out of "Mail Copy" and back into the current "Mail" folder. Clearly, it would be a mistake to simple drag them from one location to the other, since the "Contents" files and ".plist" files wouldn't match.
I would be extremely grateful for any guidance the Mail authorities who contribute to this forum might be able to give.
Also, for the life of me, I cannot figure out where the emails actually reside. The "Mail" folder contains a subfolder entitled "Mailboxes" and it contains subfolders for each mailbox like "Action.mbox" and "Hold.mbox." Then, inside each .mbox folder are other files and usually one folder. Most of these files have names like "content_index," "Info.plist," "mbox," and "tableofcontents." And there is a folder labeled "Messages" and it contains numerous ".emix" files and one "tableofcontents file." My confusion begins when I open a particular POP account folder and find .mbox folders also located there and those folders also contain .emix files. I've searched the entire knowledge base, and I find no explanation anywhere of which files/folders are located where and why.
Many thanks for your time and trouble, Jay

The easiest way to combine the old folders with the new is to use the "Import" option in Mail's File menu. Consult the Mail Help topic "Importing email into Mail" for comprehensive instructions for doing that. In your case, the "archived" messages will be the ones in "Mail Copy."
The actual messages are stored in individual *.emlx files, inside each mailbox folder's "Messages" folder. (For instance, you would find a message in a locally stored, root level mailbox "Action" at path ~/Library/Mail/Mailboxes/Action.mbox/Messages/xxx.emlx, where "xxx" is a number.)
Some of the files you mention are leftovers from Mail 1.x & are not needed with Mail 2.x. They won't do any harm if left in place, but you can remove them if you wish. (I suggest making a backup of the entire ~/Library/Mail/ folder beforehand, in case something you need accidentally gets deleted.)
These files are not needed by Mail 2.x: "content_index," all "tableofcontents" files, & files named "mbox." All folders with names ending in ".mbox" are needed, since they contain the .emlx files. You may also find folders in ~/Library/Mail/Mailboxes/ with no ".mbox" extension pared with folders of the same name with the ".mbox" extension (like "Hold" & "Hold".mbox") -- do not delete any of these, as they contain "Messages" folders as well.

How to deal with multiple Android ressolutions with Flash- AIR games

Hi,
I have some Flash games that want to make run on different Android devices. How do we do so? I've seen that in one of my games, while I check "full screen" when exporting, the game area is not taking all the available space on the screen. I guess that's because the aspect ratio.
I've seen this nice tutorial to solve that problem on Flex apps/games: http://gregsramblings.com/2010/05/06/scaling-an-adobe-air-application-to-fit-multiple-reso lutions-and-netbooks/
Is there any similar solution for flash based games?
Thanks!

That article looks like it's geared towards desktop applications, and it makes sure the window never gets bigger than the original size.
You will read, any minute now, that a lot of people set the stage to not scale, and then use layout code to position the interface to look right, and will even take note of the DPI of the device to make sure that buttons are the right physical size. That's fine for typical utility apps, but if you have a detailed illustrated background, or any sort of fixed bitmap art, it may not be the right way to solve the problem.
The way I solve the problem is to not do any scaling at all, I leave that up to Flash, but I have spare content off the edges of the stage, that will be revealed on wider or taller screens.
The first time I used that approach I made the Flash stage be 480x320, and had extra content above and below the stage, to a total height of 360. That single file would exactly fit the iPhone screen and also the different aspect ratio iPad. On the iPad you would see the extra content.
That works fine if you layout for the widest device, and a have extra content for the less wide devices, but there is only one device less wide than the iPhone, the iPad. So now I have switched the technique to horizontal.
My stage is now 1024x768, and there is a lot of extra content off the left and right edges. I have enough there that it will still fill the screen on the widest device, which is the new Samsung Galaxy Nexus.

How to deal with multiple sessions?

My application has requirement that number of users can log simultaneously. They can search documents, browse the site, etc. Now the funtions they can perform depend on their user type. So to keep track of their userids and usertypes, do i need to create different sessions for each of them?
If yes, how do i tackle such a multiple session problem? ( Say if an user of type A clicks the search documents button, how do i know which session he belongs to?)
If no, what else can i use?

Hi,
You only need to maintain different user types and assign one or more types to your users. You can have another table that say what privileges each user type has. Then the first time the user logs in, you fetch this information and store it in your session. Then when the user tries to do something, all you do is get his user type and see if the user type has permissions to do that specific action. You then allow or disallow him from doing the action.
Hope this helps.
Cheers,

How to deal with multiple pages of smart forms

Hi everyone,
i have two pages in smartforms but whenever i show smart form through my program only first page is shown not the second one. i tried with next page attribute of both pages but no resolution.
thanks alot in advance

Which solution did you choose ?
(1) main window on the two pages

- - Begins with nodes to print on first page
- - Then a command node force end-of-page
- - Then some nodes and a table node that are to be printed on second page

How to deal with file dir? what format of dir should be?

Hi Kamlesh,
Thanks for your response.
Actually, In the "Process External Bank Statement" window, i see that there are few entries which is for the previous year and which has not been reconciled. I have never worked practically on BRS and hence, i am scared to make any changes in the clients database without being confident on what i am doing. I need to reconcile for one of their Bank a/c for the month of April '08. I have the copy of the statements for the month ending 31st Mar 08 and 30th Apr 08. The closing balances are as below:
31/03/08 - 2300000.00
30/04/08 - 3100000.00
Now my OB for Bank a/c for April '08 in SAP is 2300000.00 Dr.
When i go to External Bank Reconciliation - Selection Criteria Screen (Manual Reconciliation), here are the detail that i enter:
Last Balance: INR -7,000,000.00000 (Grayed out by the system)
Ending Balance: INR -3,100,000.00000 (Entered by me)
End Date: 30/04/08 (Entered by me)
"Reconciliation Bank Statement" Screen opens up and shows the below balances in the screen:
Cleared Book Balance: INR -7,000,000.00000
Statement Ending Balance: INR -3,100,000.00000
Difference: INR 3,800,000.00000
As per the Bank statement, i have found all the transactions listed out here for the month of Apr '08 but, i also found that the open transactions for the previous month from April '08 have been lying in "Process External Bank Statement" window.
Could you please help me solve my issue as to what needs to be done or could you also get me some links from where i can get few documents for processing External Bank Reconciliations?
That will be of a great help for me. I need steps as to what needs to be done first and then the next so that i can arrive at the correct closing balance for the month April '08.
Thanks in Advance....

IMac SSD full - how to deal with the two drives

Greetings all,
I've been using an iMac i7 with two drives SSC and HDD. Recently, I've been having issues with the SSD being close to full. I use it for applications only, although some apps need lots of space (iTunes, iMovie, Photoshop, etc.) I use Lightroom and have all the images on the spinning drive. Does anyone know how to deal with this issue? Any way I can move the music from iTunes to the separate drive, or any way to figure out what exactly is using most of my space?
Thanks in advance for your help.

Howto deal with multiple source files having the same filename...?

Ahoi again.
I'm currently trying to make a package for the recent version of subversive for Eclipse Ganymede and I'm almost finished.
Some time ago the svn.connector components have been split from the official subversive distribution and have to be packed/packaged extra. And here is where my problem arises.
The svn.connector consists (among other things) of two files which are named the same:
http://www.polarion.org/projects/subversive/download/eclipse/2.0/update-site/features/org.polarion.eclipse.team.svn.connector_2.0.3.I20080814-1500.jar
http://www.polarion.org/projects/subversive/download/eclipse/2.0/update-site/plugins/org.polarion.eclipse.team.svn.connector_2.0.3.I20080814-1500.jar
At the moment makepkg downloads the first one, looks at its cache, and thinks that it already has the second file, too, because it has the same name. As a result, I can neither fetch both files nor use both of them in the build()-function...
Are there currently any mechanisms in makepkg to deal with multiple source files having the same name?
The only solution I see at the moment would be to only include the first file in the source array, install it in the build()-function and then manually download the second one via wget and install it after that (AKA Quick & Dirty).
But of course I would prefer a nicer solution to this problem if possible. ^^
TIA!

How system deals with co commitments

Situation is:
PO:
1 line purchase order, account assignment category A (asset) with 5 AU (order unit) and with 5 WBS elements each on 1 AU.
1 AU=37.480,00u20AC
Invoice:
Partial invoices comming to first PO line and first WBS element (first partial invoice, not full amount)
1. invoice 19.900,00u20AC to first WBS element 0,63 AU
2. invoice 5.000,00u20AC to first WBS element 0,15 AU
3. invoice 12.580,00u20AC to first WBS element 0,52 AU
summary 37.480,00u20AC to first WBS element 1,3 AU
And the question is how system deals with co commintments when the accountant assign bad quantity to first line of PO and the first WBS element. Accountant exceeded quantity in invoice:
invoice = 1,3 AU and in purchase order is 1 AU
in this situation how co commitments are calculated ???
thanks for help

1. The system property java.library.path and likewise, the classpath one, are really only there (as far as I know) to show what was in the environment when the JVM started. Updating the properties doesn't actually change the environment. Just like you can probably change "os.name" from Windows to Linux, but that doesn't mean the system changes to run Linux.
2. mapLibraryName just translates the library file name to the system dependent library name, and has nothing to do with the actual environment.

How to deal with visession in IVI-C driver program ?

a ViSession is an identifier that corresponds to a session.
My instrument is a remote internet device . i can call VISA library to implement
communication between labwindows and my remote internet device.In this case , what is meaning of Visession
? It looks as if Visession does not have a relation to my IVI-C driver program.
if it has a relation to my driver, how to deal with the ViSession in IVI-C driver program?thank you

ViSession is necessary as part of a larger picture and fills an important role in good architecture. Intrument handles (stored as the ViSession type) are necessary for large projects, which may require commanding multiple instruments.
There is no function to call which can get or set a ViSession value, similar to the way other attributes are set with driver functions. The ViSession intrument handle is created and returned to the application when an instrument is initialized; it represents a connection with one particular instrument.
This allows users to have multiple instruments connected, which can be controlled programmatically with one application. Then, the application can quickly specify which instrument it would like to send a command, just by sending one instrument handle or another.
Yes, you could remove the ViSession as parameter in your functions, but it would cripple the big picture effectiveness of the driver. In place of the ViSession, you would have to send each function the Resource Name or Resource ID for the particular instrument as well as the Option String. So really, it is just more practical and better practice to use an instrument handle (stored as the ViSession type).
That being said, for certain functionality (adding two numbers), you absolutely do not need a ViSession instrument handle parameter. You will have to use your best judgement to determine where to include or exclude this parameter. I suggest using the ViSession instrument handle parameter with any function that communicates with an instrument.
Also, Ebalci is correct regarding the difference between ViSessions and channels. ViSessions are used to communicate with different instruments. To reference or read a specific channel from an instrument you will have to refer to the guidance in the manual for the instrument in question. There will likely be a command to select a specific channel when reading from the instrument. And for general guidance, I suggest reviewing another IVI driver, possibly for an instrument of the same class or type or maybe from the same family, if such a driver already exists.

How to deal with the depth testing of Iterator Patch?

Recently I use Iterator Path to make my effect. I met some problem. I couldn't deal with the Sprite depth testing. I found it useless to set depth testing of the Sprite Patch. And also I don't know how to deal with the layer of the subpatch in Iterator.

In most cases, simply letting things go out of scope when the method that uses them ends is sufficient. About the only time you need to explicitly set something to null like this is, for example, if you're implementing a collection class and you want to remove an entry.
