Relationship between the naa and the number LUN? (And SCSI id and mpx)
When you look at a map of storage on a Fibre Channel network I see a few different "naa" id: s for each LUN. LUNs from the same SAN naa seems similar, but always unique.
My first question is if the "naa" is based on something physical disks or if he comes an ID the SAN attached to each logic unit number as it is created?
Is it true that a name of mpx is something an ESX host can produce when no naa is known?
The final question is the SCSI id that could be seen of a LUN in the storage of vCenter views. There seems to be a SCSI id for each disk/LUN, and I wonder what this SCSI id? If it was only a single disc, it might be a physical serial number of the drive itself, but when you look at a LUN composed of several discs there must be something else.
Its just only usually know the WWN for each unit number logic is unique.
Channel is a former SCSI reference - very rarely used nowadays, and, as you mention, is almost always '0'.

Relationship between the list and ListField...
Hey people of Java...
I can't thank you enough for your answers because I'm really starting to "grok" the paradigm of Java.
Another came today I'm having problems understanding I deconstruct this app MemoryDemo...
In the screen of the demo is these two lines:
Get and display the list of customers.
_customerList = CustomerList.getInstance ();
_customerListField = new MyListField (_customerList.getNumCustomerRecords ());Well, now I understand the first line perfectly. She develops an object with the contents of the customers it contains.
The second line calls a custom ListField routine that I show below:
the final private class MyListField extends ListField
{
public MyListField (int numEntries)
{
Super (numEntries);
}}
Here is the part that I don't understand:
It seems to appeal to both the MyListField() and the super() is simply the NUMBER of elements required, but not * that * list to use. Exactly how is MyListField() or super() knows how to use the list of customers? I ask because this exact routine is used a few lines more later (in the part of the main screen) to do the same thing for a list of the records of the order - even once without any reference to which list to use.
It doesn't seem to be an explicit connection or the relationship between the _customerList and ListField is building. Is somehow deconstruct '_customerList.getNumCustomerRecords ()' to its root and use _customerList somehow? I don't think that I changed the call to this:
_customerListField = new MyListField (_customerList.getNumCustomerRecords ());
_customerListField = new MyListField (PICK_A_NUMBER);Where the constant is: public private static final int PICK_A_NUMBER = 50;
And he ALWAYS displays a list of customers (though now with only 50 files). How to do know?
Thanks in advance!
-John
"I guess that somewhere in the interior architecture of the ListField, he knows that he has to paint the whole - one at a time - when put on the screen - that's it."
Fix.
This is the great thing about ListField. It attracts only those who are on the screen. If you use ListField draw a list of 10,000 rows (I tested), and it will only extract and draw the 10 that he needs.
"Again, I don't find any explicit loop where it is through each element and then calling drawListRow()."
Good yet once, it is not there.
"Maybe one day I'll be able to pay it back here."
It would be great.

Looking for info on the relationship between libraries, albums and photos in the Photos app. I can create several libraries containing photos and unique albums. Can I put the same photo in libraries and the different albums? By making a copy it creates a link to the original or a new photo? Where are located the photo files? When scanning photo to my Mac Pro files are placed in a folder structure, copy these photos in an album Photos using the original file or he places a copy in a database?
Bottomline, I'm frustrated by the method of collection, the albums, the place and date. I want store related photos in a separate album. Example: A library for a family, containing albums of members of their family. Maybe the photos have duplicate in different albums.

What is the relationship between the library of Photos and the iPhoto library?
I'm asking this question here because I can't find all the relevant information online.
I was dealing with imac a client recently who had a full boot drive. I noticed that his old iPhoto library used 126GB while she had already made the transition to the Photos. His photo library said that he was using a lot more (200 + if I remember correctly). I copied the iPhoto on an external drive library and deleted. Then, I opened the contents of the package and imported pictures remains in program pictures to make sure that I wasn't actually remove all of his memories. Once the work is finished, I was surprised to see that there are more than 6 GB of free space on his computer. What gives? Is there a relationship between the old iPhoto library and new photo library? If so, what is it? Is what I did without danger? I understand at the time that she will not be able to return to iPhoto. But what I'm missing?
Thanks in advance for your comments.
No - they are totally separate - connection or relationship of any kind is not
or the other can be deleted without any effect on the other - but it won't save much space at all and is not recommended - which is exactly what you have seen- Photos saves disk space to share images with your iPhoto or Aperture - Apple Support libraries

Relationship between the samples through the second rate and sampling
I was wondering if someone could clarify the relationship between the samples through second rate and sampling.
I have USB6008 and USB6363 of the tips that I work with in Measurement Studio.
For the nec USB6008 entry differential (up to four channels of HAVE), if I put a sampling frequency to 8192 samples per second, and I updated 2048 samples per channel with:
Task.Timing.ConfigureSampleClock ("", 8192, SampleClockActiveEdge.Rising, SampleQuantityMode.ContinuousSamples, 2048)
Am I right in assuming that:
- through the 4 analog inputs 8192 samples will be collected every second
- 2048 samples will be taken by way of analog input for each scan
- The time between two successive data points is 1/2048 seconds (about 0.5 ms)
Hi DKIMZEY,
The help page for the "Timing.ConfigureSampleClock method" should have a hypertext link to the page "Sample clock" in NOR-DAQmx help, that contains this text: "this sample clock sets the interval of time between samples. Each tick of the clock starts the acquisition or the generation of one sample per channel. "When the sample clock frequency is 8192, then the time between two successive data for a single channel is 1/8192 seconds. The time between the data points on two adjacent channels is controlled by the clock to convert, which can be controlled independently on most devices (up to a point).

Hi all
I appreciate your help. And I hope that this issue has been addressed previously, although I couldn't find any solution there.
I manage a domain windows 2008 with 3 domain controllers. Recently my workstations continue to fall out of the field. I get "the trust relationship between this workstation and the primary domain failed" to many workstations.
I know how to fix properly, use netdom.exe. But the mistakes keep coming back. I don't know where to look for the source of this error. A possible problem might be the time in any field is out of sync. But all my workstations synchronize with the domain controller with the primary domain controller role and seems to work correctly.
Are there other sources, that I need to check? This is getting frustrating.
Thank you much for the help.
Sincerely,

What is the relationship between the source code (LKS) file and the process file (L4P)?
I know that Lookout produces a file of source code with an LKS extension when you save a file to process. Can someone explain the relationship between the two files, especially while the (L4P) process is running?
- Is this just a backup file can be recompiled in a process file?
- A file corrupt LKS cause strange problems with operation process file?
I currently have a very strange intermittent behavior with a process file run. I first thought that the problem was associated with my Fieldpoint and/or their configuration modules. Since then, I found that my process file has a file corrupt LKS. I repaired and recompiled my LKS file to a new file to process. I still don't know if I have solved the problem or not. So, the problem is intermittent, I did that about 20-30 SECONDS to resolve the problems there before he goes. Then he can not show up again for another 2-3 days.
The .lks file is just the source code of your process. It can be opened by a different version of lookout, but does not have the .l4p file.
The .lks file is not be used while a process is running. Lookout does not read the file more after his execution. So it should not affect the running process.
What kind of problem, is it?

Hi, I hope you can help with this problem. A friend has 6 computers networked to a Tower Server and have a problem. A worker student put computers into hibernation, and since then, nobody can connect to the network on this computer. The error indicates, "the trust relationship between this device and the network is no longer valid. I tried to get into the pc to try removing network and replace it, but I can't get on the Administrators account because it has been disabled. I'm at a loss on how to proceed. My friend cannot afford a service call, so I'll try to help him. Thank you
If the computer is on a domain then there are at least two accounts that can be used to remove the computer from the domain:
- A domain administrator account.
- A local administrator account.
When your friend has launched Windows for the first time after buying the machine, he was prompted to enter the name of an account. This account is created automatically with administrator privileges. He should use it now.

The trust relationship between this workstation and the primary domain failed.
The trust relationship between this workstation and the primary domain failed. This only happens on the Windows 7 desktop. It is sporadic. Add the computer account to the domain is not a viable solution. It happens far too often.
There is nothing coherent we found on systems that are removed from the field. Some time its workstations users, sometimes its laptops to students and sometimes he posts of laboratory work. Different types of systems use different images. All images are syspreped before creating the image.

I get an error, 'relationship between the workstation and the field has no confidence. "
I have a 2003 domain controller, this a job gives me an error "trust in relationship between the workstation and the domain failed" so I read I have to reset the server, remove the object and remove the workstation from the domain, but my problem is that I can not even log in as administrator to do. My admin login details work perfect on other machines, but not this one. Help, please!
On computers that are connected to a domain, you always have the choice to get authenticated by the controller of domain or the local computer. You must select the local computer, and then use a local administrator account.

Relationship between the user and account in IOM DB
Hello
do you know how is set up the relationship between the user's record in the USR table and an account of application instance in the table form of process (as in UD_LDAP_USR)? I analyzed records from both tables, but failed to find the key to the relationship between the records in these tables.
Peter
The table Ouedraogo is the link between all the tables of an instance of a resource. The ORC_KEY is the process instance key that links the tables of UD_XXX. And there is also the USR_KEY which connects to the table user.

We strive to integrate the OPA attributes to the Cloud Service Oracle tables to store session data for the customer portal users.
We tried mapping the attributes of the OPA with relevant tables of cloud Service Oracle? Is there any installation of additional data to create to retrieve the session data for the particular user / contact?
We managed to save tha data in arrays of cloud Service for users of ananymous and also well regarding customers portal users but to preconfigure data do we need to do any additional configuration / mapping to the contact table?
Please help on the establishment of the relationship between the contact and Global (new table created in cloud Service) tables.
Thank you
Vivek
Hi Vivek,
To load data from the Contact in the the OPA policy template, you must configure the widget of the OPA. For instructions, see the following articles:
- Incorporate an interview that uses data portals in Oracle Service Cloud Customer Portal
- Deploy and configure the sample OPA widget
- Insert the widget to sample in a customer portal page
Obviously, you need to do the mapping in OPM as well, but even if the mapping is correct, you will not be able to load the Contact data unless the widget of the OPA is implemented.
See you soon,.
