11g Upgrade - removal and new parameter list queries

Hi All,
We are planning to upgrade the 10.2.0.4 E Business suite (11.5.10.2. ) database to 11.2.0.1.
We have few removal and new parameter list in 11g database based on the note 216205.1
We will be having the compatible mode as 10.2.0 before and after the upgrade until the system gets stable. So until we change the compatible to 11.2.0, do we need to have the parameters in the removal list or we can remove that even if we have the compatible as 10.2.0 during the upgrade.
There are also two new parameters optimizerautostats_job=false and sec_case_sensitive_logon = FALSE.
Please let us know if we can have these new /removal parameter changes when we have the compatible as 10.2.0 in 11g database.
Thanks & Regards,
Rakesh

Rakesh,
Please let us know if we can have these new /removal parameter changes when we have the compatible as 10.2.0 in 11g database.You can have those parameters, and you can remove it later once you are done with the upgrade.
Note: 881505.1 - Oracle Applications Release 11i with Oracle 11g Release 2
Adjust the Initialization Parameter File for the New Release

    Hi Anurag,
    Thanks for your questions.
    1:Is there change in DB architecture as CUIC is the only option as compared to previous linux version UCCX ?
    I assume this is from the tables regarding historical data. The database schema essentially remains the same since UCCX 9.0 had CUIC too and we had a seperate DB Space for CUIC and we still continue with that. The traditional historical tables remain and the replication process remains the same too.
    2:Is there any version change for Linux OS used as VOS,
    The Linux version is Red Hat Linux 5. To be precise:
    [root@uccx10pub /]# cat etc/redhat-release
    Red Hat Enterprise Linux Server release 5.7 (Tikanga)
    3:Is there any API architecture change in UCCX 10 from previous releases ?
    I can answer this more of an overview. The only enhancement in the API side is the introduction of REST API step in the script editor. You can now make REST calls from the script and this ofcourse opens up a whole new world of possiblities.
    4:Since from UCCX 10 , we can only use either CAD or Finnesse at one  time, whats the impact of changing this after some time in production,  let say , i used CAD for 2 months and then i decided to move to Finesse,  whats the impact ? or is it a smooth change as switching CUIC and HRC  in previoius release ?
    For the scenario you mentioned, there is absolutely no problem. The point to note is that the Finesse services are activated/deactivated but the CAD desktop services are ALWAYS running. The only condition to keep in mind is that you can use ONLY ONE type of agent desktop at any time.  Also if Finesse is not used and CAD operations are used extensively, it is advisable to shutdown the Finesse service.
    5:Is 3rd Party UCS hardware supported by UCCX 10 instead of using Cisco manufactured UCS , can i use HP hardware for Virtualisation ?
    Yes, it can be used. This is something called as "Third party specs based specification". The most important things seen for compatibility are:
    Inter CPU Model
    It it is on thVMWare Hardware Compatibilty List
    You can get more information about this on the "Can I use this server?" section of UC Virtualized Hardware page:
    http://docwiki.cisco.com/wiki/UC_Virtualization_Supported_Hardware#.22Can_I_use_this_server.3F.22
    6:Is Host name change supported?
    Yes, the hostname change is supported. The prcocedure is documented in the UCCX 10.0 Administration Guide:
    http://www.cisco.com/en/US/docs/voice_ip_comm/cust_contact/contact_center/crs/express_10_0/configuration/guide/UCCX_BK_W1AF9DDD_00_uccx-admin-guide-10.0.pdf (Pg 168)

  • 11g upgrade pros and cons

    Folks,
    If there's already a similar thread, apologies in advance.
    I wanted to gather some information on the pros and cons of upgrading to 11g from 9i and from 10g (Enterprise Editio) rdbms on Solaris.
    What are the challenges you have faced (especially if you have tweak SQLs/optimizer etc.) post upgrade?
    Any issues DURING the upgrade?
    If I missed anything obvious that worth bringing up, please do so.
    Thanks for your time!
    Regards..

    Pros/cons depends on the database type and activities ( no. of user/ data/ transaction etc).
    but i would suggest upgrade your database (9i is history).
    you will get many new features in database which are not available in 9i.
    1. upgrade on test server
    2. check the performance
    3. everything goes well
    4. upgrade on live server

  • DVR Upgrade; Remove Old DVRs from List on Web and Mobile User Interfaces

    I have upgraded two HD DVRs to the hardware with more storage space.  The new DVRs appear on the list of available DVRs on both the web and mobile applications for DVR management.  The old, uninstalled DVRs also continue to appear.   How can I remove the old DVRs from these lists?

    Provided you returned the old DVR's using the materials and instructions that should have been provided when you received your new units, the old DVR's should disappear from your account in a week or two after they've been received and processed by Verizon.   I just renamed mine to "Returned" or something like that so that I would know to ignore them until they went away.
    If it takes more than one full billing cycle and they still haven't disappeared, then I'd call to find out why they are still in your account (i.e. have your tracking information ready because it sounds like they may have gotten lost along the way).

  • Differents between upgrade installation and new installation

    Our processes have some misbi
    Our processes sometimes misbehave. We don't know the cause. We have a DR site so we moved everything there and then everything worked with no issue. The applications are using SQL 2012
    SP2.
    All the servers are the same in the DR site as the primary site, One of the things we know to be different is that the SQL server installation in the primary site is an upgrade from 2008,
    and the one in the DR site is a new installation of SQL 2012.
    Do you think there could be a different behaver that is related to type of installation?
    Does it make scenes to reinstall the SQL in the primary site as new installation rather than upgrade?

    Hello,
    Adding to Shanky response, do the DR SQL Server instances were configured the same (about parallelism, memory, tempdb,
    etc.)?
    Hope this helps.

  • Cannot remove report parameter list

    I want to use a form to control all my report parameters and pass to report thru a run_product function.
    However, I found that I cannot remove the default parameter list in report program. Every time the parameter list will prompt out. How can I remove the parameter list in report and it will never prompt out when I run that report?

    Hi Kane,
    You can hide the paramform by using an extra parameter in the paramlist you are filling in your form.
    Use:
    add_parameter(<parameter_list_id>, 'PARAMFORM', text_parameter, 'NO');
    Hope this helps

  • Infoview pick list values and CR parameter values are not the same

    Hello All
    We have created created Crystal Reports based upon BW Query using Static Parameters as recomended by SAP. When we run the query in InfoView the Pick List is dynamically updated and returns the correct data for selection. When The Crystal Report opens and you wish to navigate through the report using the parameter selection the selection criteria has not been maintained by BW and does not match the Pick List.
    Can you please advise if there is any way to make this work?
    We ar using Crystal Reports 2008 version 12.3.1.684
    on BOBJ XI 3.1
    Any help would be appreciated,
    Phillip

    Hello Ingo
    What is strange that in InfoView the pick list is only dynamic the Parameters when the document is open (in InfoView) are not dynamic. An example would be Searching on Material. In Info view the pick list provides all the materials to select from. Once though the report is open the parameter list on the left hand side could be seen as blank as it refers to the static list that is not manually maintained within Crystal Reports or provide a list of details that has no reference to the dynamic selection as returned from BW as it is a static list that was loaded with Crystal Reports Designer on creation.
    What we are wanting to achieve is that Info View Pick List is Dynamic and the Parameter list that can be used to navigate within the document once opened is dynamically refreshed to be the same as the Pick List provided by BW and InfoView.
    Is this possible?
    With CR Designer if we use Do Not Show, Info View no longer provides this parameter on the left hand side.
    If we use Editable the list provided in InfoView is equal to the static list as maintained within CR Designer.
    We have not tested Read Only Yet so I am not sure if this could be the solution or not.
    Any ideas would be of great benefit

  • I made an IMovie project and I can't now make a DVD of it.  A window says there are problems and that they are shown in the User Parameter List.  I am at a loss.  Don't know what to do.  HELP

    I have made an IMovie consisting of slides and some video.  I cannot create a DVD with it.  A window tells me there is a problem and that the problem is listed in the User parameters.....I am at a loss.  There are hours of work in the Movie.  Anyone have a thought?  HELP

    problem and that the problem is listed in the User parameters
    Can it be
    Error -50 paramErr  Error in user parameter list
    Can there be any external hard disks - if so How is/are it/they formatted ? Must be Mac OS Extended (hfs) if used for Video.
    UNIX/DOS/FAT32/Mac OS Exchange - works for most but not for VIDEO.
    What this means in Your situation is above me.
    • free space on internal boot hard disk? How much ?
    Video codec
    • streamingDV, AIC etc. (not .avi, .mp4, .m4v, .wmv etc as they are containers not codecs)
    Pictures
    • in what format ? .jpg, .bmp, .tif, else ?
    Audio
    • from where/what format ? iTunes, .avi, .mp3, .aiff, else ?
    The "com.apple.iMovie.plist" file
    Many users has not observed that there are TWO libraries.
    • Library - at root level
    • Library - in user/account folder - THIS IS THE ONE to look into
    from Luke Burns
    I fixed the problem.. but it was very, very strange. I had a very long section for credits and set the line spacing to 1.0.. for some reason this caused it. I removed it, and it worked fine. I put it back, and I couldn't preview or play the video.
    I don't know why that could cause that big of a problem, but it did..

    You need more free space on your hard drive.

    After phone support from apple I ended up creating a new project and adding all 117 clips back in individually till I found out what clips flagged and would not allow me to export. I had 3 I deleted and replaced and everything works now 1hr after tedious work....
    Where do Your material come from
    • Camera
    • External hard disk
    • USB-memory
    And all are connected so that iMovie can find it ?

  • Dynamic Parameter List questions: Length and Custom Values

    I've got a Crystal Report that I want to use Dynamic Values for.
    Right now... this report is simply a "SELECT stuff  FROM table" SQL query... with a parameter that the report uses to filter.
    I use a "Select DISTINCT value from table" to generate a list of values. I put those values into a txt. I then import the text into a static list. This creates a parameter list that is 11 "pages" long on the parameter screen. I also have "custom" values allowed. This is to allow for "new" values and also allow not needing to browse 11 pages for one or two known values.
    If I turn the parameter into a Dynamic List based on the same Select statement it stops at 5 pages, obviously cutting off half of the possible values.
    Dynamic List also removes the ability to do Custom Values. The filter option wouldn't be a bad alternative BUT it don't work for pages 6+ that aren't there.
    How can I remove the 5 page limit (or whatever it is) for Dynamic values?
    Thanks
    Chris
    Edited by: WernerCD on Aug 4, 2010 4:14 PM

    There is a limit of 1000 records in dynamic parameters. You can change this by adding a registry value:
    registry key : HKEY_CURRENT_USER\SOFTWARE\Business Objects\Suite 11.0\Crystal Reports\DatabaseOptions\LOV
    and then add a key called MaxRowsetRecords and give it a value.
    if you have Crystal 2008 then the above registry folder will say Suite 12.0.

  • How to customize Category and Category items list while creating New Model

    Hi,
    what the most convenient way to customize the Category and Category items list while creating New Model?
    This is standard:
    Now, what we want to achieve, is to customize this menu, to:
    1. Display in the Category window only f.e. two categories:
    - EA Diagrams
    - BPM Diagrams
    2. In the EA Diagrams, we want to have f.e. four copies of City Planning diagram, each of them should have different elements available, f.e. in the first copy, only Architecture Areas shall be made available, in the second one Architecture Areas and Business Functions, in the third on f.e. only Business Functions shall be made available. Additionally, it should behave like a hierarchy ... meaning you can create the second diagram, only as child (related diagram) of the first diagram etc.
    I know, excluding the particular diagrams/diagram elements can be configured using the right/profile settings, but how to:
    1. Customize the standard New Model menu window
    2. Create copies of City Planning Diagrams with different set-ups
    3. Set the relationship between diagrams
    Is such a configuration change possible?
    Thanks a lot for your help!
    Regards,
    Rafal

    Now, what we want to achieve, is to customize this menu, to:
    Question #1. Display in the Category window only f.e. two categories:
    - EA Diagrams
    - BPM Diagrams
    Click on Tools => General Options=> Model Creation
    Click on Properties => at right of Default category set
    Note : Model template does not work as Category. We can't set. An enchancement request has been open to SAP
    In the following example I defined a new default (MyNewDefault.mcc). As you can see only BPMN models are available.
    To create a new category set with BPMN choice
    a) Copy default.mcc in MyNewDefault.mcc file.
        Go to Tools=>General Options=>Model Creation : Select your new category
        Go to Tools=>General Options=>Model Creation : Edit properties and remove all things you does not want keep
    or
    b) Go to Tools=>General options=>Model Creation : Edit properties and click on Save as button and specify the file name "MyNewDefault".
        Quit the window.
        Select you new category : Go to Tools=>General Options=>Model Creation : "MyNewDefault"
        Edit properties and remove all things you does not want keep.
        Save you new category
    Question #2. How to define copies/replicas of existing diagrams
         Wrote an extension
    Question #3. How to make sure, particular diagrams can be used (created) only on predefined "levels" and how to set the parent-child relationship, so that PD enforced it directly when creating a new diagram.
         Specify yours conditons in your extension attached to your model
         Example : When the user want create a child diagram :  You can display a list of Parent Diagrams to select from.
         You can set in your extension by VBScript parent-child relationship
    Question #4 In the EA Diagrams, we want to have f.e. four copies of City Planning diagram, each of them should have different elements available, f.e. in the first copy, only Architecture Areas shall be made available, in the second one Architecture Areas and Business Functions, in the third on f.e. only Business Functions shall be made available.
    If I understand well your question. I suggest to take a look in
    Repository=>Administration=>Objects Permission Profile
    You can specify objects to show, mask, deactivate at model level.
    You can specifiy your own metadata.
    But I'm not sure you can mask, deactivate functions following diagram selection. It seem to specific.

  • How and where should I create a parameter list

    Hi, I4m trying to create a parameter lists but I don4t know where and how.
    I guess as a program unit but as function or procedure, sorry I4m new on this for that I4m finding this a bit difficult. Please, someone could help me to understand this:
    PROCEDURE Run_Emp_Report IS
    pl_id ParamList;
    BEGIN
    ** Check to see if the 'tmpdata' parameter list exists.
    pl_id := Get_Parameter_List('tmpdata');
    ** If it does, then delete it.
    IF NOT Id_Null(pl_id) THEN
    Destroy_Parameter_List( pl_id );
    END IF;
    ** Create the 'tmpdata' parameter list afresh.
    pl_id := Create_Parameter_List('tmpdata');
    ** Add a data parameter to this parameter list that will
    ** establish the relationship between the named query
    ** 'EMP_QUERY' in the report, and the record group named
    ** 'EMP_RECS' in the form.
    Add_Parameter(pl_id,'EMP_QUERY',DATA_PARAMETER,'EMP_RECS');
    **Pass a Parameter into PARAMFORM so that a parameter dialog
    will not appear
    **for the parameters being passing in.
    Add_Parameter(pl_id, 'PARAMFORM', TEXT_PARAMETER, 'NO');
    ** Run the report synchronously, passing the parameter list
    Run_Product(REPORTS, 'empreport', SYNCHRONOUS, RUNTIME,
    FILESYSTEM, pl_id, NULL);
    END;

    Hi,
    What you've pasted the code here is absolutely correct.
    You'll have to write the code in Forms builder.
    You can either paste the same code in a procedure & call that procedure
    from button's When-Button-Pressed trigger or paste the code in
    your button's When-Button-Pressed trigger like this :
    DECLARE
    pl_id ParamList;
    BEGIN
    ** Check to see if the 'tmpdata' parameter list exists.
    pl_id := Get_Parameter_List('tmpdata');
    Run_Product(REPORTS, 'empreport', SYNCHRONOUS, RUNTIME,
    FILESYSTEM, pl_id, NULL);
    END;
    However, don't write the code in a function as you will need to return some value from the function.
    Thanks,

    A. Repair the Hard Drive and Permissions:
    Boot from your Snow Leopard Installer disc. After the installer loads select your language and click on the Continue button. Then select Disk Utility from the Utilities. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list.  In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive.  If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer. Now restart normally. 
    If DU reports errors it cannot fix, then you will need Disk Warrior (4.3.) if DW cannot fix the drive, then you will need to reformat the drive and reinstall Snow Leopard.
    B. Make a Bootable Backup Using Restore Option of Disk Utility:
    Open Disk Utility from the Utilities folder.
    Select the destination volume from the left side list.
    Click on the Restore tab in the DU main window.
    Check the box labeled Erase destination.
    Select the destination volume from the left side list and drag it to the Destination entry field.
    Select the source volume from the left side list and drag it to the Source entry field.
    Double-check you got it right, then click on the Restore button.
    Destination means the backup volume. Source means the internal startup volume.
    C. Important: Please read before installing:
    If you have a FireWire hard drive connected, disconnect it before installing the update unless you will boot from this drive and install the update on it. Reconnect it and turn it back on after installation is complete and you've restarted.
    You may experience unexpected results if you have installed third-party system software modifications, or if you have modified the operating system through other means. (This does not apply to normal application software installation.)
    The installation process should not be interrupted. If a power outage or other interruption occurs during installation, use the standalone installer (see below) from Apple Downloads to update.  While the installation is in progress do not use the computer.
    D. To upgrade to Lion:
    Purchase the Lion Installer from the Mac App Store. The download will start quickly. Lion is nearly 4 GBs so a fast internet connection is essential. Download time could run upwards of 4 hours depending upon network conditions and server demands at the time.
    Boot From The Lion Installer which is located in your Applications folder.
    Follow instructions for installation.
