• Questions about the configuration of the cache for use with partitioned off-lot...

  Once more, I give it a try to see if we can make use of the new partitioned (split) off-heap storage and are having problems with the configuration of the cache (including configuration files).
  
  The problems that I had, it seems that < high > units should be specified for the entire cluster (or perhaps for a node? not sure yet!) while < original-size > & < size > is specified by partition. Is this correct? That's the way it was intended (for me it would have seemed more logical to also specify < high-units > per partition since I guess overflow checking and expulsion is made by partition)? The way I read the documentation, it seems that all three should be per partition if < partitioned > true < / partitioned > is specified.
  If I value < > 1 mb high-units (as i belive I should if it was per partition) I get the impression that I posted in a previous question (a message to info on some missing index data, then the crash of nodes in cluster with some of out of memory error).

  Sorry, my description is very confusing. High units is by cache. What I was trying to say, is that cache mapping can train additional units high to affect the memory required by the node. Since multiple caches can map to the same pattern, especially if you use wildcards in the mapping, you must consider the total number of hidden units of high times. It is true or not caches use different services.

  You are also right about high units, applying to the partitioned support cards. You could have easily expulsion are happening as you describe. We must take another look at the configuration because it is too easy to make a mistake.

  As expected, the allocation of card support splitting is lazy to avoid the problem you described. The worst case situation, I was trying to explain can occur if you have caused all buffers to be allocated based on the data before all other nodes could take some of the partitions.

  Kind regards

• HP Officejet Pro 8500 A909a USB 3 questions about the configuration of the network - port USB3 problem

  Fujitsu Windows 7 laptop (all USB2)

  used the full software and installed a printer HP Officejet Pro 8500 A909a Series as a network printer.

  The printer installed fine and don't have USB connection

  All the software and scanning twain installed, so I was able to scan the copy etc.

  I could browse and choose my PC from the front panel of the printer

  However, it was Tuesday confirmed to a friend that their printer would work on a new laptop - bought the laptop

  Fujitsu - but more recent model with 3 USB ports

  I have install and then used the same FULL configured driver to be installed (V14)

  selected as a network printer and then, during the installation, I get an error hardware error USB and USB drivers

  All the USB works, that I've used - BUT the printer is networked and no USB used

  tried to download the driver and install it-exactly the same question

  SO I configure using the devices and printers 'add printer' network and installed

  I can print OK

  BUT no analysis facilities

  and on the façade - cannot see the new PC to scan to

  The only real difference, is that this PC has USB3 and only mine has USB2

  DO not know why on a network installation USB even when searching for

  It's a problem because Drivet package not has not been updated for USB3 - y at - it a patch?

  Thanks for any help / advice

  Hi etaf,.

  I guess the short answer is: Yes, the problem with the software and the 3.0 Port.

  The long answer with a possible work around is as follows: first of all, the software looks for minimum requirements. Because the software is older, he doesn't know what a 3.0 port. You are right when you say that it should work since you do not use the USB and use wireless instead, but this is not the case.

  There is something we can try, but I can't guarantee it will work. I thought first we could connect a USB cable and run the software made to force the software to see the USB port, but then the software wouldn't even get far enough because you can't plug the cable to the most later in the installation.

  My second thought and most promising suggestion is to connect the USB cable (although we do normally not until the software prompts us to) and use the installation wizard HP Print to get the insteaad of software to use the CD or download from the printer driver page. Still, I can't say with certainty that it works, but I don't see why it would not be worth a try.

  If it works, and we get the software installed you can convert the USB connection to a wireless connection using the software. Fingers crossed! Download and run the with the following link. Printer HP install wizard for Windows

  If this does not work, or you don't want to bother with it (not worth trying), I might consider getting a new model of the printer. You can even call HP. They might be able to offer a discount on a newer model. If you are in the Canada, U.S. dial 800-474-6836 or you can Contact HP worldwide.

• Some questions about replication

  Hello

  I have several questions with vSphere replication.

  -Can I replicate a server ESXi isolated VM, without vCenter?

  -If I can, you could turn on the VM as if necessary? because when I turn on the virtual machine, I manage in vcenter console

  -If I reproduce it in vCloud, how should I? I need to download a camera in my office and the other in my cloud?

  Thanks for help

  Hello

  -Can I replicate a server ESXi isolated VM, without vCenter?

  You have vCenter Server to replicate virtual machines inside or between data centers. VR as a product is installed on vCenter level and is only available if you are using vSphere Web Client connected to the server vCenter.

  -If I can, you could turn on the VM as if necessary? because when I turn on the virtual machine, I manage in vcenter console

  vSphere replication is not disrupt the work of the virtual machine. It monitors which changes the VM and the changes are replicated

  -If I reproduce it in vCloud, how should I? I need to download a camera in my office and the other in my cloud?

  If you build your own private cloud using vCloud Director VR allows to respond directly to the vCD, as VR currently supports only VC as target. You can however check VMware vCloud hybrid Service: overview | United States if you want to replicate in VMware vCloud hybrid service, workloads

  Hope this helps

  Kind regards

• Questions about replication of virtual machines using EMC storage

  Hello

  If we have a configuration on 5200 VNX and ready to replicate to Dominican Republic

  What are EMC replication Solutions, if not use Recoverpoint?
  I have to add licenses of replication with the Suites of the app for that?

  and whether using Recoverpoint, it is essential to use SRM for replication can be configured using Recoverpoint and VNX licenses only?

  and for another program installation is with 10 GB iscsi ports, what are the possible solutions?

  Thank you
  
  

  There are several choices for replication with EMC VNX. You can use Mirrorview. MirrorView/S (synchronous) is for short distances and Mirrorview/A (asynchronous) for longer distances and time of higher latency and low latency. You will need a license from EMC Recoverpoint or Mirrorview. Recoverpoint appliances can now be virtual with version 4. ISCSI is required for a virtual Recoverpoint deployment.

  You don't have to use RS with Recoverpoint, although I would recommend that you do. SRM automates many manual steps that are necessary to retrieve your VMs. SRM will be integrated with Recoverpoint or Mirrowview and you will be able to script recovery plans. In the case of the manual recovery plans would be required and will need to be updated.

  You can also duplicate with suppliers other than EMC software. VMware has built the replication that is fine. Veeam also sells software for replication.

• Small Question about Advanced Configuration settings

  When you change an advanced value of a VM, why the new object is created

  New-Object VMware.Vim.VirtualMachineConfigSpec

  When we look at the object of $vm.extensiondata.config this object looks like for me VMware.Vim.VirtualMachineConfigInfo no "context".

  So my question... to rephrase and perhaps provide some clarification... Why is context and not ConfigInfo?

  Objects of the type of information are present when you retrieve a vSphere object, objects of type Spec are used when you configure a vSphere object.

  It's the Get-ter and Set-ter from the point of view PowerCLI cmdlets.

• (Maybe stupid) Question about ASDM configured PIX PIX VPN

  I have two PIX515 running v7.2 (1) and ASDM 5.2 (1).

  If I use the VPN Wizard of the ASDM to configure a site to site VPN, this process takes care of the need to create split tunnel parameters, so that the outgoing traffic non - VPN inside each PIX is managed properly?

  Hello

  By default, all client VPN traffic is encrypted and sent to the VPN server, Split tunneling is used for client vpn remote to exempt a particular traffic to be encrypted and tunnel to the VPN server so that the traffic will be sent in parallel to the internet or local.

  During the configuration of site to site intuitively that when the configuration of the remote networks on both sides that communicate together by the IPSec tunnel and all other traffic is routed to their destinations without encryption.

• Question about the configuration of virtual computer file and the working VM location

  I noticed one of my virtual machines had two data warehouses listed under "Items" in the vSphere Client.

  After some research autour, I found the virtual machine files are in the correct data store, but the 'VM-configuration file' and 'Place of work VM' are in another data store.

  Can I combine all in the same database?   I'd rather have the config and the workplace on ma who has a lot of main storage.  For some reason, the configuration file and the location of work were created on a local storage on my host.

  Any suggestions?

  Thank you

  David Moore

  You can use Storage vMotion to migrate only the virtual machine configuration file to the desired location, just start the wizard of vMotion and storage step 'Select the data store', click Advanced, and you will see the option to select a new destination for the configuration file data store.

• Question about the configuration of Netbackup

  DB version: 11.2
  Operating system platform: AIX 6.1
  NetBackup version: 7
  
  I need to configure RMAN backups on tape for my Production DB using netbackup as the MML. The given statement was
  

  Shutdown all DBs running from this Oracle Home        # Missed this step
  cd $ORACLE_HOME/lib
  ls -lrt libobk.a                                                                                 
  ln -s /usr/openv/netbackup/bin/libobk.a64 libobk.a
  Start all DBs

  I did all the steps above except knock down DB linking this ORACLE_HOME. I even tested backup of the control of the band successfully file after creating symbolic link. Tonight at off-peak hours I will run the full backup DB. There will be no problem because the DB is not bounced? I can't test it now that it's production.

  Hello

  did all the steps above except knock down DB linking this ORACLE_HOME...
  There will be no problem because the DB is not bounced?

  Don't worry, the installation of MML and link building can be made without stop since Oracle 9i running instances.
  From:
  http://docs.Oracle.com/CD/B10500_01/server.920/a96566/rcmconfg.htm#453248

  You don't need to start or stop the instance during the installation of the management of the media library.

  You seem to be on 11 GR 2, then everything should work properly.

  I can't test it now that it's production

  Do the backup will now generate additional I/O now as well...
  Kind regards

• question about clustering configuration in LCDS3.1

  In the doc LCDS3.1, it is said "using the"
  shared-backend = "false".
  the configuration attribute does not have a single, consistent view of the data in the cluster. When two clients are connected to different servers in the cluster, if they make conflicting updates to the same data value, each server applies these changes in a different order. The result is that clients connected to a server to see a view of the data, while the clients connected to other servers have a different view. The conflict detection mechanism does not detect these changes as long as conflicts. If you need a single view of data where both clients are updating the same data values at roughly the same time, use a database or some other mechanism to ensure that the regular blocking is done when updating the data in the back-end system".

  This means using the static-backend = "true" IS guaranteed a single consistent view of the data in the cluster? Or it means that I must use the level of database locking in both cases?

  Here is some info on this to Mete Atamel, engineer of the LiveCycle Data Services team:

  When shared-backend = true, a single consistent data display is guaranteed, but it's not because of the shared-backend itself, but rather the fact that once shared-backend = true, there is a single database used by multiple instances of the LCD screens.

  Imagine a scenario where you have two LCDs nodes in a cluster with the destinations of two data, on node1 and Node2, on management and they are grouped (via JGroups). You can have these destinations maintain their own DB, and when a change occurs in a node¹s destination, destination of the other node gets a message JGroups and updates its own DB. It works but it is not ideal because at some point, you¹re try to maintain the State of cluster even on two different DBs and there are times where connected clients do not get a consistent view of the data.

  Instead, you can use a single database and have the two destinations, talk with the same PB, if you have a single consistent view of the data. When possible, you enable property shared-backend in the destinations of LCD screens, in this way when a single destination updates of the DB and send a message of JGroups the other destination, the other destination do not have to update the DB again, instead she simply passes the update message to clients connected without sending it to the adapter.

• Question about the configuration of wireless networks

  I managed to set up my laptop and desktop computer to access the interest through a Belkin WLan modem router. So why can't they access each other or the printer that is attached to the office. Computers independently access the router via a wireless connection.

  The printer is connected to the desktop via the parrell port. Each are running xp home.

  Hello

  In so that they can access the printer, you must have the shared printer. Go to start-> settings-> fax and printers, then go to your printer, right click and go to share. Then share it. Now go to your cell phone and go back to the printers and Faxes page. Now click on add a printer and click on that it is connected to the network via another computer and add it to your laptop. Now it should be usable on the network. So that your computers to see each other, they will have to be interconnected, in a literal sense. Access networks and create a LAN or WLAN, first of all, the office, then the laptop. After that the two of them, they should be interconnected and see themselves. A routher is dandy, but for some reason, some computers do not always act as well as on a network up to that force you to.

• Basic question on the configuration of the OVD

  Hi gurus
  I have a basic question about the configuration of the TPM. I have all the "employees" in Active Directory and 'Employees + external users' in OID. The employee user password is maintained in AD, while the same for the external user is maintained in OID.
  
  Query:
  I need to configure authentication for an application for the employees present in the AD and present external users in OID. I have to join the profiles of employees present in AD and OID. Even if the employees are present in the OID, I don't want to configure for authentication of the OAM.
  
  How can I implement this using OAM and OVD.

  I got your condition.

  You said that OID contains external users as well as employees. You manage a container separated for employees in OID. If so, you job would be easy. If there is no container separated for employees on the OID and storing all users (employees and external users) in the same container (default: cn = Users, dc = xxx, dc is com) then you can get the list of AD users only with the following ldapsearch command:

  ldapsearch h Pei d 'cn = sleep '' w sub s b '' 'objectclass = user' SamAccountName

  Create three adapters OVD:

  1 adapter used (this should point to Active Directory)

  2. users adapter (when creating this, you have to exclude users AD, just similar to find the above option).

  3 create the adapter to store as the clubs above two adapters.

  Now, OAM should talk to store adapter.

  I hope this helps.

  Thank you

• Question about KB 2033173 - SNMP configuration

  Hi guys, I have a question about KB 2033173. It is said

  below is an example of the host SNMP Configuration profile:

  Port 161

  Community

  Community 10.0.0.1@0 receiver

  [...]

  Please note that the recipient's address contains a space, not a "/" as input to the command line.

  
  

  I wonder why the "10.0.0.1@0"? I think it should be "10.0.0.1@161" because the port number is 161. Thank you.

  
  

  
  

  Yes, you are correct and also keep in mind that there is a lot of difference with the SNMP agent without traps (use the port UDP/161) and SNMP agent with traps (use port UDP/162).
