• Error creating the store of data on iSCSI LUN (EMC CX4/120)

  I run an error when you try to create a data store on a Clariion CX4/120 system.  Connectivity to the San is performed via iSCSI.  I exhibited with success the target on the storage card and it shows in Configuration > storage adapters > vmhba33 > Details.  It has a capacity of 5.37 to.

  When I go to Configuration > storage and select Add..., I can select the disk/LUN.  The LUN appears here as well.  When I click Next, it fills the device information and location and also reported "the HDD is empty."  After 10 minutes, it generates the following error...

  Call "HostDatastoreSystem.QueryVmfsDatastoreCreateOptions" of object "ha-datastoresystem" on ESXi '172.20.100.78' failed.

  I did some research on Google and looked around here on the website of VMware, and I can't find any references to this error.  Are there log files for the process that I can look into?  I must engage EMC and see if there is a problem with the SAN itself?

  It has a capacity of 5.37 to.

  VMFS data storage limit is 2 TB less than 512 bytes. Try presenting small LUN, then it should work.

• Why there is no data type that stores only date (without the part of hour)

  Hi all
  
  Is there a particular reason to not have a data type that stores only date (without the time part) in ORACLE - I'm asking this because the DATE (without a time) is a type of data very frequently used in any application.
  
  Thank you.

  In fact, I was reading about the types of data...

  We have numbers with details. According to the argument above it is not necessary. We need only a default type NUMBER.

  It depends on. Much of the work that we do, we only create just like NUMBER and don't worry precision. However for financial purposes, a clarification for the monetary values of the application can be very important.

  In the same way do all the varchar2 (4000) character data type. Why we would require an option to specify the length... ?

  Because you can limit the size of the string that can be stored.

  I see what you're saying, but that's just the way it is. Why Oracle would need to confuse the issues by having several types of data to store the type Date and DateTime requiring an explicit or implicit conversion to be necessary, or provide an indicator of accuracy against the date where this indicator of precision would take of additional storage space on something that is already only 7 bytes.

  There will be internal historical reasons why it has happened this way... but really there is no need to worry.

• 836: failed to create the shared memory data, error 22 store segment

  Hi, I am new to timesten and databases in general, and I'm testing the database timesten to test.
  
  I am running ubuntu linux in virtualbox and have java 6 is installed. So far, I installed the timesten database and configured the sys.odbc.ini to create a new database. However, it seems that I can't connect to a database.

  The command failed.
  
  what I am doing wrong? What can I do?
  
  Thanks for your time

  A data store active TimesTen consists of a single shared memory segment allocated from o/s. The size of this segment is PermSize + TempSize + LogBufMB + ~ 20 MB. This allowance will not allow the o/s unless the 'package' kernel parameter has a value greater than the requested size of the segment. According to the Guide of Installation TimesTen, you set various parameters of the kernel on the appropriate values (memory shared, semaphores, etc.).

• Find the store of data with more free space.

  So I'm trying to build a script to configure the virtual machine.

  I'll have it retrieve the node to keep newly available vm out based on the cluster, I said to use. I'm just using the Random function to do that then I select a node in the cluster.

  Where I have questions, how can I

  find the data store less used, based on a particular data store naming scheme.

  I want to say is:

  Hypathetically, I for example named data warehouses:

  store data-prod-01 200 GB free

  store data-prod-02 500 GB free

  free data-prod-03 10 GB store

  free data-qa-01 200 GB store

  free data-qa-02 1000 GB store

  I want to throw in a piece of code to tell him to watch data warehouses "datastore-prod *" and place the virtual machine on the store of data with the most space. (that's assuming that the vm will agree on the DS and let fresh generals)

  I guess I want to know if it is possible?

  I would also be concerned about scenario that perhaps the vm should I build just will not match on any of my other data store. I guess I need a logic to check if it is still possible.

  This is more than a wish rather than a necessity. I'm thinking if I just read the info, or use a cvs file after running the script. Any recommendations would be greatly appreacted.

  Hello, drivera01-

  You should be able to do this with a very small amount of code.  Download all data warehouses that correspond to the model name, sort free space (in descending order) and select the top one.  As:

  ## get the datastore matching datastore-prod* that has the most freespace$oDatastoreWithMostFree = Get-Datastore datastore-prod* | Sort-Object -Property FreespaceGB -Descending:$true | Select-Object -First 1
  
  ## if the freespace plus a bit of buffer space is greater than the size needed for the new VMif (($oDatastoreWithMostFree.FreespaceGB + 20) -gt $intNewVMDiskSize) {<# do the provisioning to this datastore #>}else {"oh, no -- not enough freespace on datastore '$($oDatastoreWithMostFree.Name)' to provision new VM"}
  

  The second part, where it checks for sufficient freespace on the data store that has the most free, can be updated to behave as you need, but that should be the basis.  How does this look?

  You can use the data store provider.

  It is documented in the vSphere PowerCLI Administration Guide that was installed with PowerCLI.

• Space in the store of data not released when a virtual machine is removed

  Hey all,.

  I have a game fairly simple up - two servers ESXi 2 Terminal servers. I'll have a problem, but with space in the store of data not be released on one of them after that I got a clone to the virtual machine, made my changes and removed the original. I can find no record anywhere, using vSphere (not in the inventory or when I browse the data store), but the HARD drive space using the server is still assigned somewhere.

  Any body have tips on where to find or how to fix this if it is indeed a problem?

  Any help is greatly appreciated.

  Thank you.

• [ADF, JDev12.1.3] Which is the right place (for example, bean or AM) to create and store secret data that the user is unable to intercept?

  Hallo,

  in my page, when the user clicks on a button, I'have run an operation and in particular generate a code PIN and password that the user must not not know/interception.

  The STEM must be kept "secretly" in the comic book.

  I created a function to generate the PIN code in the 'Utils' to the ViewController project class.

  In the managed bean associated page I would deal with the click of the button through its ActionListener function.

  In this function I would also generate PIN call the "generatePIN" works and finally store the PIN in the comic book.

  Is the bean, the right to 'place' where build and store the PIN in the database?

  Maybe I'd better to generate the PIN and then store it throug a function of the module of the Application?

  Thank you

  Federico

  Well, he should go to the model because it is part of business process and is not part of the presentation of data.

  (AMImpl, VOImpl, or same ViewRowImpl are good places to write such code)

  The STEM must be kept "secretly" in the comic book.

  I don't know what that means exactly.

  Aspect of security, no matter where you place code (in the model or ViewController) because both are executed inside the Java virtual machine server-side.

  If you need to secure communications between WLS and DB, then open the database by using the SSL protocol connection (or create the stored procedure and generate PIN directly in db)...

• ODI 12 - problem with missing data in the store column data types

  Hello world

  We have recently installed Studio 12 on Oracle RDBMS ODI. We have created some topologies, contexts and the logical architecture. We have created the necessary templates and made reverse engineering. The strange thing is when a model data store opening, we have noticed, the data types of its attributes are not displayed and cannot be selected in the drop-down list because they do not exist yet. You can see the image below.

  

  So the mappings are not correctly executed because on the stage of the creation of work tables CREATE script was not generated correctly. (It's something like "CREATE TABLE < name > ()")

  Anyone can give an idea what could be the reason for this and how might be solved?

  Any ideas would be appreciated.

  Thank you in advance.

• Cannot create another store of data on a LUN

  I have a 2 TB LUN and on that, I got a 500GB data store. I want to create a different data store on the same logical unit number but when I go to create the LUN does not appear in the list of available storage. I think it was LUN 0 before but now LUN 0 is the local drive of the ESXi server.

  Hello

  While there are solutions involving fdisk, a data store should really be 'one by ONE', and the graphical interface makes it easy to do something else. There is nothing to win have two warehouses of data on a LUN - just make a big.

  Don't forget that a 2 TB LUN is actually oversized, that the limit is 2 to 512 b.

• issue of configuration for the store of data/LUN iSCSI

  Hi all!  I am all new to VMWare and iSCSI, and I have a question about data warehouses regarding being mounted on an iSCSI target.

  Here's my setup.  I have a Dell PowerEdge R810 connected over a link to 10 GB dedicated to a Dell PowerEdge 2950 that I use as a SAN.  The R810 has no hard drives in it, it starts ESXi on a redundant configuration of SD card integrated into the server.  My SAN software is Server 2008 Enterprise with Microsoft iSCSI software Target 3.3 installed.  I created target 1, LUN 0, 800 GB .vhd file sitting on a NTFS partition and set up a store of data on it in VCenter.  The data store is the size of the entire iSCSI, 800 GB target.  I have my first virtual server up and get 50GB of space between the data store.

  Here is my question: can I create several virtual machines using the data store I put in place?  I know it sounds like a stupid question, but my concern comes from some reading I did on several computers, access to a single LUN.  If I set up another virtual machine, it will explode on my SAN file system as two virtual machines would be to access the same big VHD file on the NTFS partion, or I'm far from base?

  Issue of bonus points:

  I have an another R810 that I will be online soon.  Assuming that I am OK to add more virtual machines of my first machine, pourrais I connect this box in the data store as well and create virtual machines, or should I set up a separate data on another iSCSI target store?

  Thanks for your patience with a new guy.  I searched and read for hours, and I could have read too much so I thought that I had just askt experts.

  Hello and welcome to the forums.

  Can I create several virtual machines using the data store that I put in place?

  Yes.

  If I set up another virtual machine, it will explode on my SAN file system as two virtual machines would be to access the same big VHD file on the NTFS partion, or I'm far from base?

  No, you should be fine.  One thing to keep in mind is that the Windows/MS iSCSI target is not a supported storage solution.  There could be problems of scalability with iSCSI Windows/MS, but you'll be fine in a VMware perspective.

  I have an another R810 that I will be online soon.  Assuming that I am OK to add more virtual machines of my first machine, pourrais I connect this box in the data store as well and create virtual machines, or should I set up a separate data on another iSCSI target store?

  You could, but I personally would put in place a different data store on another iSCSI target.

  Good luck!

  Critics target DataStore No. IKM is selected for this interface.
  
  But, I chose IKM SQL to ADD the FILES in the tree structure Module knowledge in respect of integration after selecting I click on save and then new open pop-up window and you are prompted for the name of the file by clicking the search icon I have chosen a path, and I gave him the name of file then recorded...

  Thank you
  Gunuru

  Hi Gunuru,

  Problem 1:
  In your interface, go to the mapping tab.
  Click "Target data store" on the top right of your screen and then enter a name for the data (bottom) store.

  Problem 2:
  Your probably forgotten point 4 and point 5 of this article: http://www.oracle.com/webfolder/technetwork/tutorials/obe/fmw/odi/odi_11g/odi_project_ff-to-ff/odi_project_flatfile-to-flatfile.htm#t6

  Just click the workflow tab, click your staging area and choose your IKM.
  You must also choose a LKM on the part of the source.

  It will be useful.

  Kind regards

• Creating a store of data from local hard drive

  If I wanted to use the free space on the computer host ESXi as a data store, I need to partition the disk hard until I have install ESXi on it or I can do after?

  Default install ESXi uses your hard drive and converts it to a VMFS volume if you install it on local storage. If you plan to use the entire disk, just install ESXi with General settings you will have already created for you a data store.

• Creating a store of data on ESX 3.5

  I have a setting wrong until a data store on ESX 3.5. Recently, I got a Dell PowerEdge 2900 (two Intel Xeon Quad Cores with 32 GB of RAM, just in case where this info would be important) and installed ESX Server 3.5 on it. Before installing ESX, I created two virtual disks on the server, one that was used to install ESX and VMs on and another larger virtual disk which should be used as the primary storage for virtual machines, images of .vmem more etc. The largest virtual disk consists of eight SAS 400 GB hard drives in a RAID 5 configuration. ESX is installed and runs on the first virtual disk very well. The problem I have is that when I try to add the virtual disk larger than a store of data in VMware Infrastructure Client it shows 2.54 TB capacity, which is what it should be, but is showing that 555,99 GB available space. This doesn't seem fair to me. This virtual disk has been defined, so it is completely empty. Maximum RAID 5 configuration must use the equivalent of one of the 8 disks for parity data, theoretically giving me ~ 2 TB of usable disk space to use as a data store. Is there something I'm missing here? Any help would be appreciated!

  Welcome to the forums - the problem is the size of the largest LUN - maximum ESX and ESXi recognized the LUN size is 2 TB by maximum configuration http://www.vmware.com/pdf/vi3_35/esx_3/r35u2/vi3_35_25_u2_config_max.pdf- so you'll have to sculpt your drive to the top in less than 2 TB LUN.
