Migration problem

We have a cluster with 6 ESX host. (3.5) .with pool of a resource with 16525 mhz and 132213MB.no resources reserves and stock normal.and about 10 virtual machines are outside the resource pool.

Configuration of ESX host: HP PROLIANT ML370G5

Processor: 8 * 2.499 GHZ

HT: inactive

Question: the cluster is enabled with HA and DRS. DRS configured with fully automated.we have sufficient resources available on ESX (3.5). But still a lot of VM migration are underway within the cluster. Do not have any idea why this is happening. We have a lot of papers about resources allocation changed newspapers for virtual machines. And because of these migrations, virtual machines performance is very slow

All mounted data warehouses are NFS that we used to host VMs.

VCenter 2.5

Please help me solve this. Thanks in advance.

You will need to check the imbalance of the bunch. If the cluster is an imbalance, for some reason, then DRS will try to balance. You will find some details on this procedure here:

  • Server Migration problem

    Hello

    I'm planning on migrating a number of servers between the 2 groups in the same data center. At the present time, that the two groups do not have access to the adapter network same vMotion is not possible, it is very good and will be resolved shortly. However I get an error but another message which reads as follows:

    The virtual machine requires hardware features that are not supported or disabled on the target host:

    * General incompatibilities

    If possible, use an active cluster with vMotion compatibility (EVC) Enhanced; See article 1003212.


    CPUID details: incompatibility at level 0 x 1 'ecx' register

    Bits of the host: 0110:0010:1001:1000:0010:0010:0000:0011

    Required: x0xx:x01x:1001:10xx:xxxx:xx1x:xxxx:x 011

    I'm assuming it's because the processors on hosts are slightly different between the two groups, all hosts in two clusters are IBM HS23 blades but...

    Group 1 - Inter (R) Xeon CPU E5 - 26700 2.60 GHz

    Group 2 -Inter (R) Xeon CPU E5-2650v2 @ 2.60 GHz


    Can someone please advise if there is anything I can do to get rid of this error, if I turned off the VMs system first I can migrate their and they function without problem however, I really want to avoid if possible system failures.


    I'm assuming that the solution may involve the CVS (this is currently disabled on the two clusters) but I would like that confidence that allowing this cause no problem for connection etc.


    Thank you



    It's true. you need downtime to allow CVS on an existing cluster.

    but that's why I suggesting a different solution.

    (1) create a new cluster, select CVS on that.

    -Please find planning intel CPU would be appropriate for your two models that you plan to mix. [Let me give you a simple example, if I have two hosts of AMD, one with AMD Optron G1 and the other with AMD Optron G2 CPU, I would create a cluster of empty with active VCA, basis for VCA updated AMD Optron generation 1, powerdown all VMs running in both hosts, put them in maintenance mode and drag the cluster out of maintenance mode and begin to power on virtual machines]

    -you have two processors in your next guests clustered computers. I don't know too much what appropriate Intel CPU would be at there place for them, please try to find this first release.

    Group 1 - Inter (R) Xeon CPU E5 - 26700 2.60 GHz

    Group 2 - Inter (R) Xeon CPU E5-2650v2 @ 2.60 GHz

    (2) now clear out a host of each departure of cluster 1 and 2, which will be your initial test environment, bringing virtual machines in this third group. While doing this, you may need migration cold of the two clusters, but more likely, you would be able to bring virtual machines to at least one of your cluster using vMotion.

    (3) if things work out well for you, free plan all hosts to join this group and get rid of the remaining clusters of empty.

  • Migration problem reports: file not published online

    Hello everyone!

    I'm doing a migration of forms and reports on the Apex, but I can not download these reports 3: I got the error "XML report not published online", as you can see here.

    Anyone know why this problem appears, and why only 3 reports have this problem?
    I checked all the reports, but I couldn't find any big difference between these 3 and other...


    I also have another problem with reports settings: in the XML file, I "& param ' but Apex seems not to accept it. I modified the changing XML file "& param"to": param", but it still does not work.
    How should I write the settings in the XML file?


    Thanks in advance,
    Stone

    Hi Pierre,.

    Thanks again for the redirection on your sample XML report files.

    First, the file upload issue you reported related to the XML file containing a multibyte, but the file was not coded UTF - 8. When I saved the file with UTF-8 encoding value, I then could successfully download the file to my project of Conversion of forms. I noticed that your XML file contains several elements of with the SQL statements for your report. Even if such a file can be downloaded on your forms Conversion project, project pages associated with the reports only expect a element in the file and therefore will not work correctly. As a solution, I suggest that you take a backup of your XML file, and then edit the file to remove additional items . It will only contain a single element of with the SQL statement to be used in the conversion process.

    For reports with parameters, my suggested workaround solution would be to remove the parameter of the SQL statement references, download the report and then try to convert it. If successful, an interactive report Oracle APEX is generated, based on the SQL statement from the report of the Oracle. Once the interactive report has been generated successfully, update the Oracle APEX page to include a new point (e.g. list selection) takes over the possible user parameter values. Change the source of interactive report for the new reference point. The interactive report then only display information based on the setting selected by the user. I hope this work around will allow you to continue your conversion process. Please let me know how you get on and also if you have any other problems with the conversion process.

    Kind regards

  • Email migration problem

    I'm trying to migrate my mailboxes to mail in OS x 10.5 PPC G5 to mail in OSX 10.6 Intel. The migration tool did not move to the data. I tried the import tool and which failed. I moved the data manually and the boxes appear but not the content. The PPC machine is dead, but the HD is fine. What should I do to recover these data? Kirby

    Well, if the hard drive is fine, you must make sure that the users-> yourname-> library-> Mail and Mail downloads are displaced in their own folder on your desktop on your new machine folder.   You can then use the Mail tool Import Mail to the application in the Mail menu or file of the mail app to import the mailboxes, and then click the folder that you created on your desktop to keep these messages.

    Remember, it's only for locally stored e-mail messages.  If you use IMAP or Exchange, this information may already be on the server and you can connect with the settings on your new machine.

    Unity 4.0 (4) SR1

    Exchange 2000 BOX

    Users were migrated to an older exchange server, less stable, to a new through the usual advertising------change of method of moving users from one server to another.

    The old server is still in place and active.

    When it breaks down, the UNIT is unable to deliver messages to subscribers.

    Do I have to re - run exchange on the unit configuration wizard to define the new server as the main? Otherwise, any ideas why the old server to be up? What is the workaround-difficulty?

  • Removing VCS of TMS and TMSPE migration problem

    We prepare to start using TMSPE, however it must first disable replication on all VCS via MSD MSD Agent.  There is a VCS that have failed has been deleted afterwards, but we cannot delete TMS because TMS Agent replication is enabled.  We cannot have the Agent MSDS tab to disable the replication because the VCS is offline (i.e. it was removed) - it just goes to the 'Connection' tab whenever I try.

    So, how can we migrate to TMSPE if TMS don't delete us the VCS in offline mode or at least turn Replication Agent MSDS for it?

    Hey Nick

    Try to run this SQL query:

    USE TMSNG

    UPDATE field_SystemField SET BolValue = 0 WHERE field_Field_Id = 1072

    UPDATE Cluster SET EnforceTMSAgentDataReplication = 0

    This should clear the replication on all VCs added to the TMS (even the zombie ones like the one you have), once it is executed, you can try to purge the VCS.

  • exec_sql. PLL in the form of 11g

    Hi all

    I've struggled for some time with a form of migration problem.

    Reminder: My business is migrating to Oracle 10 g 11 g form through all the screens, libraries and all objects in general. A few days ago, I found a screen which opens a connection to the database and execute instructions (grant privileges, change password), this form uses exec_sql.pll which is apparently a package included in the implementation of forms since version 6.

    The problem begins when I took the current exec_sql.pll of my deposit and try to compile in Builder 11g.

    the main problem is that there is a function that does not compile:

    PACKAGE currconn BODY IS

    -This is the definition of package for currConn

    -For Developer/2000 R 2.x, which makes implementation of the STPROC. HSTDEF

    -procedure.

    FUNCTION get_curr_conn RETURN pls_integer

    IS

    hstdef PLS_INTEGER;

    BEGIN

    stproc.hstdef (hstdef); Obsolete in Forms11g - form of Oracle 11 g Migration

    connection_id: = EXEC_SQL. DEFAULT_CONNECTION;

    Tensioner: = EXEC_SQL.IS_CONNECTED;

    RETURN hstdef;

    EXCEPTION

    WHILE OTHERS THEN

    RETURNS A NULL VALUE.

    END;

    END currconn;

    According to the documentation of oracle forms, this guy here [stproc.hstdef] is now obsolete. Therefore, because that's why I can't continue with the compilation. the logic to connect to the DB and execute some instructions is present across several screens, so ideally, I would like to correct the root cause of which is the library and not apply with a workaround in each single fmb

    Issue.

    1. is there any place where I can download a newer version of exec_sql.pll?

    2. If the answer to #1 is NEGATIVE, is there another way to get around the above function?

    OK, time for me to chime...

    If you need not STPROC so it is not a problem because it no longer exists.  What you need to do, is not to use an old pll.  Since functions supported this old pll are now based in the forms, the library of the add-on should no longer be needed and your form should compile.  If it is not the case, your form code must be updated correctly.

    If your concern is that you have a lot of modules should be updated, you can use the JDAPI or CAPI to perform updates all modules quickly.

    If you do not correct the code at some point, you will continue to have this problem every time you upgrade.  What will happen when you need go to v12?

    Hi Ralf,.

    is '113.2013 - Jugendsozialarbeiter & #x2F;. Clubleiter - S Jugendfreizeitzentrum & #xFC; dclub F & #xFC; rstenwalde - Verein BSG Pneumant F & #xFC; rstenwalde e.V.' the text of a link? Or is it posted somewhere else? It looks like a double exhaust system takes place.

    4.2 there is a new parameter called "HTML escaping Mode" which is by default the value 'Extended '. You can find it under "Edit Application Properties"-> security-> security of the browser. It may not be visible if 'Compatibility Mode' ('Change the properties of Application'-> 'Properties') is not defined > = 4.1. So, you'll need temporarily to 4.2 make visible this attribute.

    If you set it to 'Basic', you should be able to experience of the old behavior. But I think that we still have to examine why you have the double escapement.
