What is the tool to bless and why it prevents a clean reinstall?

I'm helping a friend who has erased his internal HD due to a problem thinking it was a startup disk. She also didn't

have a backup.

I made an installation on a USB disk using diskmaker. When I try to start now the Option button, I get the recovery partition disk utility.

When I select the bootable as the boot floppy installation disk, I get a message that it cannot be used as the startup disk. The Bless tool was unable to put the current startup disk.

What is the tool to bless and is there something that can help me to do a clean install of El Capitan?

Thank you

Well, first of all, if you used your identifier Apple to download the operating system and then using your license to install on the machine of someone else will not work because the license is not transferable and is linked to the Apple ID used to get. the recipient would not be able to update the apps or reinstall because they need your Apple ID and password.

If you use recovery, why not just use to reinstall the OS - have you tried designate the hard drive? I would try disk utility to repair the hard drive and the re-partition/format. As far as I know, bless tool is part of the operating system and tries to find a boot disk; I looked, and although I found a lot of questions, I was not able to find a definitive answer.

  • What is the difference between AXIEM and EMSIght? What are the benefits of AXIEM by EMSight if any?

    I wonder what are the differences between AXIEM and EMSight. Are associated with application? One is better than the other? Please explain.

    AWR estimated AXIEM most powerful plan EM Simulator around.   AXIEM is at the center of continuous research and improvement, while EMSight is only worked on if revealed serious flaws.  Here is a summary of the differences:

    Mesh

    • EMSight must mesh the nearest grid drivers using rectangles.  This causes the mesh to have more elements mesh when there are small and large geometries.  The grid should be small enough to capture the small geometry but then causes large geometries to mesh more.   In addition, angled or curved structures causes inefficiencies mesh.

    • AXIEM STS forms, rather than a grid.  In addition, the mesh can be rectangle or triangle.   This allows a much more efficient mesh.   AXIEM generally have a much more efficient

    • AXIEM contains the ability to process forms to clean geometries that cause inefficiencies of the mesh.  EMSight does not have this feature.

    • AXIEM can forms thick metal mesh, EMSight can not, and user must make approximations when thick metal will change coupling (loss is recorded properly with the thickness of the metal)

    Ports

    • The ports are for the most part similar, but parasites due on AXIEM ports are less.  In addition, the AXIEM has a side wall, thus the effects of not move of the terms of reference of the edge of the line are a lot less AXIEM in.

    • Ports can be added to most any place in geometry with AXIEM.  For EMSight, the ports are usually only added outside the geometry and have limitations to the aircraft on either side of the reference speaker.

    Problem solvers

    • EMSight does not have a low frequency Solver.  Stop low-frequency and then extrapolate to DC.  This usually works well, but you must take into account if the extrapolation is accurate.  AXIEM presents both a low and high frequency Solver so will do better in a low frequencies generally much better in DC.

    • Solver of EMSight scales O (n) ^ 2 for memory and O (n) ^ 3 for the moment.   It has a special algorithm to break the question of memory, but the question of time is the killer.  AXIEM has a direct Solver which scales in the same way and an iterative Solver which will scale O (nlogn).   In other words, AXIEM can solve a lot of bigger problems than EMSight.

    • Several AXIEM processes are multithreaded as EMSight.

    Speaker

    • EMSight is inside a perfect driver side wall.   This works well if you the circuit is in the same cavity.  If not, you must know the rules of them on to the forms of space of the flanks and how that much to extend the port could reference planes.   AXIEM is not here.   AXIEM does not currently have to simulate a perfect driver side wall.

    I don't know that I missed a few aspects of the tools.   From the point of view of the AWR that AXIEM is the tool of choice, except in a few cases have been EMSight may be required.

    Hi Ashish I put in it,

    Now, only I realized the problem is with the lifecycle ADF

    If I place a logging operation in the method of the request form, we will see that the method is called twice and that is why exceptions are thrown. Change the property of refreshment of the invokeAction of prepareModel to renderModelIfNeeded. The commit operation will work with this change and the invokeAction will be called once again because it will be necessary. Once again, the point of the example is to call the invokeAction but for the validation button, as is evident, the value of prepareModel was not enough. The value renderModuleIfNeeded ends the validation operation. .

  • The upgrade of the tools of vm and vm hardware version

    Hi all

    I've recently updated our vCenter for version 5.0 Update 1 and we have a mixed infrastructure composed of running ESXi 4.0, 4.1 and 5.0 ESXi ESXi hosts.

    I need some clarification on versions of database tools to the virtual machine and vm hardware version.

    I read that if I pass the hardware version to 8 on my virtual machine, then no matter what host running a lower than 5.0 ESXi will not be able to see these vm... is this true?

    Also vmtools being dependent on the ESXi host version, what is the best way to upgrade for my vm vm tools? Upgrade of all virtual machines that are on 5.0 ESXi hosts?

    Really, what I'm asking, is how to manage the tool of vm and vm version levels of material in a mixed environment of ESXi.

    Work wants everything to be more 'late', but it is simply not possible with some hosts on ESXi 4.0 and ESXi 4.1.

    Thanks in advance.

    Yes, it's true. HW version 8 is only supported on ESXi 5.0 and later.

    In order to upgrade the version of the material, you must be on the last tools first in any case - this is the recommended method. In order to upgrade the version of HW, you need to fuel the VM so this failure should be taken into account in your courses on the latest plans.

    Personally, I use PowerCLI to upgrade all the tools and cela as part of the monthly patch cycle when failures are already planned. You can install the tools without a reboot in advance by using the switch - NoReboot in your syntax PowerCLI (although there is a clause in the help files that says something along the lines of reboots may still occur in some circumstances, but I haven't done this experience yet).

    In regards to the HW version, I try to upgrade downtime is planned and only to force an upgrade, if I need a feature not supported on an earlier version.

    in your case, if you have any mixed clusters or there is a chance that you will need to migrate a virtual computer on an older host go then the virtual hardware. When I upgraded to Version 5, I ensured that no virtual material has been updated so that all guests were on ESXi 5.0... But also rememer that new VM created on your hosts 5.x will HW version 8 and will not be able to run on hosts earlier.

  • What is the difference between EPMA and Essbase Studio

    If the two are not used to design applications?

    And a really need Essbase Studio?
    What is the difference between EPMA and Essbase Studio

    ^ ^ ^ It's a little confusing, isn't? As far as I understand the role of EPMA, it is a way to share dimensions and common data between several products Oracle EMP including Planning, Essbase and HFM. In fact, I don't know if other products live in EPMA. What is EPMA not have is a great way to supply or manipulate the dimension and fact tables (or files). Oh, there are tables of the interface, but you will write the code/use the utility of dimension EPMA to load dimensions. I must say that I never tried to load through EPMA data so that someone else will have to pronounce on it. Once the dimensions are built, you can deploy Essbase (and other products) of common and specific to the database dimensions.

    Studio is the tool you will use to go against a data warehouse, or something terribly close a data warehouse to build Essbase databases. Just for Essbase - HFM, planning, etc. are not the targets of the Studio release.

    What gets confusion / intriguing, is that when EPMA deploy Essbase apps, it uses Studio under the covers to do. So the interesting implementations where people use Studio (which is much more flexible than EPMA because it is a development tool as opposed to a dimension/data management application) to read the tables, EPMA interface (and as far as I know, the EPMA base tables) and create Essbase applications like that.

    If you think that there is overlap, I agree with you, but you can see that they are not the same.

    And a really need Essbase Studio?

    ^ ^ ^ Do not use Studio to build Essbase databases. You can go hog wild in EAS with loading SQL rules if you want, even if at some point it will be probably easier and simpler to build in the Studio. Although the Studio has been mentioned as the replacement of EAS for awhile, I suspect the effort required to build a database in Studio will keep around for quite a while EAS or Studio Lite will be out. There is a lot to say (sometimes) for the incredible flexibility EAS/Essbase-Studio requires a more methodical approach and EPMA has a very formal set of standards and methods.

    Phew, I'm sorry, I wrote a book on this subject and I bet you get a lot of differences of opinion on that.

    If you are interested in the Studio, you could do well to take a copy of 'Look smarter than you are with Oracle Essbase Studio 11' of Glenn Schwartzberg. I don't get a penny from the sale while I was among the writers of copy (Hey, I got a mention in the acknowledgements). It's a good book and an excellent introduction to the tool.

  • What is the difference between ActionEvent and SelectionEvent?

    Technical environment:
    Oracle jDeveloper 11.1.1.4.0
    Windows XP
    ----------------------------------------

    I think there is something behind ActionEvent and SelectionEvent which makes my code does not work.

    Here's my problem:

    I have three tables. One is a masterpiece, contains the summary of something. If I select a line on this chart, the second table shows some data, based on the line selected on the first table. Well Yes, it is a ViewLink, and it works perfectly. Now, I want the same thing to work between the second and the third table. If I select a row in the second table, the third table should show some data, based on the line selected on the second table. The third table is a ViewObject with some binding settings. I need to assign values to these parameters, that I get the value of the line selected on the second table. How can I do this?

    I tried to use ExecuteWithParams. Select the line in the second table, get the values, pass it in the form ExecuteWithParams, run and... it works... I get the result on the third table. Here is the code how to:

    ***
    {} public void updateTableEvent (ActionEvent actionEvent)
    DCIteratorBinding iter = gen.getIteratorBinding("SearchView3Iterator");
    Line rw = iter.getCurrentRow ();

    oracle.jbo.domain.Date strDate = rw.getAttribute ("Tgl") (oracle.jbo.domain.Date);
    String strRkno = (String) rw.getAttribute ("Rkno");
    oracle.jbo.domain.Number strRkId = rw.getAttribute ("Rkid") (oracle.jbo.domain.Number);

    DCIteratorBinding iterParam = gen.getIteratorBinding ("variables");
    iterParam.getBindingContainer () .getVariableManager () .setVariableValue ("ExecuteWithParams_pRkId", strRkId);
    iterParam.getBindingContainer () .getVariableManager () .setVariableValue ("ExecuteWithParams_pTgl", strDate);
    iterParam.getBindingContainer () .getVariableManager () .setVariableValue ("ExecuteWithParams_pRkNo", strRkno);
    OperationBinding operationBinding = gen.getOperationBinding("ExecuteWithParams");
    Object result = operationBinding.execute ();
    }
    ***

    But when I tried the same thing on SelectionEvent, I did nothing... no error and also no results. What I want is just to select the line on the second table and get the result on the third Board, not any pressure from button. Here is the code:

    ***
    {} public void onRowSelect (SelectionEvent selectionEvent)
    DCIteratorBinding iter = gen.getIteratorBinding("SearchView3Iterator");
    Line rw = iter.getCurrentRow ();

    oracle.jbo.domain.Date strDate = rw.getAttribute ("Tgl") (oracle.jbo.domain.Date);
    String strRkno = (String) rw.getAttribute ("Rkno");
    oracle.jbo.domain.Number strRkId = rw.getAttribute ("Rkid") (oracle.jbo.domain.Number);

    DCIteratorBinding iterParam = gen.getIteratorBinding ("variables");
    iterParam.getBindingContainer () .getVariableManager () .setVariableValue ("ExecuteWithParams_pRkId", strRkId);
    iterParam.getBindingContainer () .getVariableManager () .setVariableValue ("ExecuteWithParams_pTgl", strDate);
    iterParam.getBindingContainer () .getVariableManager () .setVariableValue ("ExecuteWithParams_pRkNo", strRkno);
    OperationBinding operationBinding = gen.getOperationBinding("ExecuteWithParams");
    Object result = operationBinding.execute ();
    }
    ***

    Then. What is really going on here? What is the differece between ActionEvent and SelectionEvent? Why did give me answer of difference?
    Thanks for your comments.

    What is the difference between readResourceContent and services ReadDocument...

    It is what... tell me differences...

    ReadResourceContent is used to read the documents in the repository of LiveCycle (the database LiveCycle).  ReadDocument is for reading binary files to the file system of the server (hard drive).

    If you create a file with write document\ create a directory it goes on the servers file system - its disk hard - and not in the repository of LiveCycle (the database).  Indeed, the repository may be hosted on a different server (in the case of a remote database).  If you write a file "/ apps/ki01/af-was61-pp01/AppServer/profiles/af-node61-pp01-01/uploadfiles/Test.pdf", then check the hard drive of the server, then you will see the files are there.
