  I met the same problem, and the EnableAlertDefActionConfig has been moved to the org.hyperic.hq.bizapp.shared.action package.  You should be able to change as an import in the EEManager.groovy and redeploy the new plugin from AdminHelper without any error.  I just did (took half an hour, and it was mainly to ensure that I lacked no other changes).

• clarification of the role of admin Help Desk in IOM

  Hello

  I have granted few users with the role help desk Admin, I got the below list of permissions of the document oracle.

  

  When the user tried to change the attribute of the user (name, first name etc...), he went for approval. But in the list above permission to the role of assistance, there is no mention of user to change access rights.

  How is the user was able to edit the attribute name? Is this regular behavior?  I see the admin role Viewer user has permission to modify user (attribute-level security) .

  Help Desk role inherits permissions of other admin roles (display of use / other role)?

  What is meant by request or direct exploitation?

  What is meant by scope organization permissions?

  Please provide details?

  Thank you

  Yes, you need to use in the same way, as described in the link button change user below. You must create a sandbox, apply EL expression and publish the sandbox.

  Oracle security solutions: IOM 11 GR 2 - show elements and hide the user interface based on a role

  The wink below shows the similar expression you need to set for users of the system of administration.

  

  The other activity in relation to the Helpdesk will work as it is. He expression will only hide the button change for all users except Admins system (xelsysadm). We have working in one of the previos project. This should work for you as well.

• Admins Help! Atrix Beta Update brick!

  Hey guys,.

  Unfortunetly though this seems to be my first post. I was really hoping for "Hey I love this new update Atrix" or "Hey guys im atrixdude820! ' but not...

  Tonight, I come to you guys with an intreesting topic.

  Now I signed and registered for the beta update... and all of a sudden, this evening around 6 p.m. IS, I got a popup saying that there was an update for my phone...

  so I plug it, download... done... and then install!

  The phone turns off...

  Then it turns on with the big M, and the words dual cord etc...

  It will be the black show, go a little box with an arrow of unpacking, and then about 1/4 through the bar @ bottom... IT STOPS!

  It then goes to a big! (sign of error) and little Andriod guy with an all-black screen AND DO NOT MOVE FROM THIS SCREEN at ALL!

  TO make things worse, nothing on the phone is sensitive to all! So, I took the battery and did a factory reset and still the same problem. Any help with this would be much appreciated, I'm very bored with the stupid box pop up for update every hour that's why I did the update anyway!

  Like the Atrix... just NOT update until now lol

• Just changed my Windows 7 password, and now I can't get back into my account admin help, please.

  I did not create a recovery, because the password was easy, now, it does not work.

  I did not create a recovery, because the password was easy, now, it does not work.

  If Shawn method does not resolve your problem, you can use this method:

  1. Set your BIOS so that it uses the DVD drive as its primary boot device.
  2. Start the computer with your Windows 7 repair CD.
  3. Press a key when prompted to boot from the DVD.
  4. Select 'PC Repair' in the menu.
  5. Select 'Repair' when prompted.
  6. When you are prompted, select System Restore.
  7. Configure Windows to a point before you changed the password.
  8. Plan ahead a little and create, test and document an alternative admin account, same as you have a spare emergency House key. This will save you a lot of trouble.

• How to map a role OIM11.1.2.2.0 to Helpdesk Admin role using IOM/OES

  Hi all

  I created a role called Admin in IOM account. This role needs to be able to change passwords for users. So, using OES apm that I've mapped the application named IOM user role change password to the Admin role account that I shot of OUD. After scoring in the IOM with a user with the role of account Admin, I am unable to change passwords for users. Is it possible to create a role in using OES/IOM has privileges in IOM?

  If you have questions or need more information please let me know.

  Thank you
  Jesse

  Yes, using the Admin role API you can assign users the role of Help Desk as soon as it is approved for custom Admin account role in IOM. If you need to place the code in the handler of role.

  So that means... once the Admin account is assigned to the user after the approval workflow, the role of the Admin Help Desk will be assigned automatically.

  Same scenario work in R2 we implemented and it works perfectly fine.

  You can ask questions if deal you with any specific problem / need for clarification.

• Recovery WIFI connection after sleep mode activation takes much too long

  This question of provenance in this thread: http://answers.microsoft.com/thread/b7916ba7-3e34-4ee2-a6e7-bba2fa65508b (title: "HELP!") Driver issue Microsoft Virtual Wifi Miniport Adapter (error code 31)").

  Basically, the presented solution it works for me too. However, the command "netsh wlan set hostednetwork mode = ban" does not get persistent, thereby affecting

  "stop wlan netsh hostednetwork" gets persisted, however.

  'do not command netsh wlan set hostednetwork mode = allow' does not get persistent...

  In other words, current enforcement in exactly ONE time orders-Admin-helps prompt - as soon as I wake my machine to sleep after running it, the WIFI connection gets restored quickly (less than 5 seconds); but when I check the status with "netsh wlan show hostednetwork", then the result is that the mode is set to "Authorized" again - and that means, the next time that I wake up the machine, it takes ages to new (~ 30-50 seconds) before connections WLAN gets implemented...

  Does anyone know how I can get the mode = do not allow to persist?

  Another fact interesting, that I found before I was running on the solution by using the NETSH commands:

  If I change the ' password on the reactivation of the "option of energy saving"require a password (recommended)"to"Don't require a password", it's okay, about the period of time it takes to establish the WIFI connection after wakeup (in other words, even without the NETSH commands described in this thread).

  So, from my point of view, it seems to be that something related to security (probably in association with this kind of things hosted network).

  The problem: disabling of "Protection of password on wakeup" is not a solution to everything, for me personally, as I am quite often on the road with my laptop, and I want to be sure that the data on my laptop is not accessible without unlocking the screen, in the case where the unit would get stolen or I loose it somehow... to protect all customer and other data sensitive data to this topic...

  Any professional entry of someone at Microsoft to finally have a solution for this would be greatly appreciated.

• Wp8 e-mail 8Pro, 2013 Outlook using various records of Surface

  Hi all

  I'm confused and reaching out to help.

  I have an IMAP account hosted with my ISP.  I set it up on my

  Windows 8 phone (HTC 8 x)

  Surface PRO (in the Mail application)

  Surface PRO (Outlook 2013)

  I obviously have problems with IMAP email outbound, but I leave that to a separate thread.  My question here is that all applications seem to use different IMAP folders.

  I don't have a single point of truth for junk, deleted, sent items.

  It seems that the SPMAIL uses "Sent" and "deleted".  (but I can change it)

  It seems that O2013 uses "Sent items" and "Trash."  (but I can't change it)

  It seems the uses of telephone "Sent items" and "Deleted items" (but I can't change it).

  Help!  I want just one consistent piece.

  First use of an e-mail client, it will create a few files 'default', before the synchronization on the server host. Once connected, the host server think these folder are underwritten. Go into you host server settings (ISP admin help or e-mail Web Access may be required), delete or cancel a subscription records newly created. In addition, if a "special folder" host feels, Trash, etc, were put to these newly & wouldn't file, you will need to re-point with your previous and before the previous step.

• Understand the Concept of organization in OIM 11 g

  Hello

  Say that we "Org Org B, Global help Desk" as suborganization Xellerate users and users in the framework of assistance has been given roles admin Help Desk, user as part of technical support will be able to reset the password across A Org, Org B etc?

  And say a resource is assigned to the Org as accounts available, can we restrict that this account not to be shown to the Help Desk to perform any type of management accounts-if not how can achieve us?

  Looking forward to the clarification, thanks in advance.

  Yes, using the code you can assign any number of administrative roles to a single user. For example, you can assign Helpdesk Admin role of Org A and B Org Org Helpdesk user.

  But it is only support using the code and you can automate it.

• Internal Web deployment of Android & IOS app on the same page

  HI am delopying our application on both android and IOS in the same secure Web page as 2 links.

  I use the older DPS documentation and it works for IOS.

  What should I do different for the Android? Is there a reference article?

  You have two options:

  (1) post the .apk on a website and send the link autour. The downside is that your users will need to allow the installation of app of unreliable sources to make this installation work.

  2) distribute via Google private game channel. Start with distribute Android apps in your organization - Google Apps admin help center for more information.

• go esxi hosts and virtual machines in one vCenter to another

  I built a new vCenter (Windows vCenter), I intend to move on ESXi hosts the old vCenter (Virtual appliance vCenter) to the new vCenter. I don't know if it's feasible, please notify my step is correct or not: 1) build a new vcenter 2) create a cluster with two esxi hosts first 3) Mount data (NetApp Filer Storage) to the new vCenter warehouses 4) add an empty host for the new vCenter VMs) 5 download then upload to the host in new vcenter

  Hi friend

  Its doable without any problem.

  Please follow the procedure below.

  1 build a new vCenter (your first step is correct)

  2 creating a cluster (because it is new vCenter there will not be any available host.) That is why cluster creation wizard will not get to add in the new cluster host). While initially empty cluster would be created.

  3. once the cluster is created, immediately do a right-click on the cluster and add your hosts one by one. Not necessary to cancel the registration and the VM. Virtual machines will automatically be added who were there on the data store available with all guests.

  Don't forget,

  1. we do not mount any store data in vCenter, we assemble the data store on the host.

  2. If you mount the new data store (which did not exist before), you can mount once the new hosts are added to the new cluster. (Your SAN admin help)

  3. If you want to move your virtual machines from data store before the newly added/mounted data store, please SVMotion these virtual machines (by right-clicking on the VM > migrate > data store > select the data store that is new)... Please follow the same procedure for all virtual machines.

  4. you don't need to add empty hosts to the new cluster, add just as soon as all guests without you register VMs. Later, you can migrate to other store of data according to the requirement. NO need to download or download the VM.

  5. Please make sure that your ESXi hosts will be compatible with the new vCenter. Old version of ESXi always compatible with the new version of vCenter. Just check if you have all valid licenses.

  Please let me know if you need any clarification
