The upgrade from 11g to 12 c

Hello

We intend to improve our databases of 11g (11.2.0.3.11) to 12 c (12.1.0.2). We would like to know what are the steps that we need to upgrade the position.

(1) all 11 g AWs automatically updated to 12 c? or do we rebuild US 11g AWs on 12 c after the upgrade? (We had to rebuild AWs after upgrading to 10g and 11g)

(2) are there accessories performance in 12 c, which will apply to only AWS built on top of the 12 c?

(3) we have an AW 10 g 11 g-based. Is it still compatible with 12 c AW?

Thank you

Dietsch.

Hi dietsch,

My answers are online.

(1) all 11 g AWs automatically updated to 12 c? or do we rebuild US 11g AWs on 12 c after the upgrade? (We had to rebuild AWs after upgrading to 10g and 11g)

The upgrade from 11g to 12 c requires no AWs to rebuild.

(2) are there accessories performance in 12 c, which will apply to only AWS built on top of the 12 c?

He might have a few new optimizations that have been incorporated into the version of 12 c of the AW you will not have access to until you rebuild the AW, but that does not prevent you from using the 11g version of the AW of 12 c.

(3) we have an AW 10 g 11 g-based. Is it still compatible with 12 c AW?

Yes, 12 c is backward compatible with an AW 10 g.

In addition, once you upgrade it has some new features that you can use for OLAP.  The display below describe some of them.

  • The upgrade from VMware Workstation 12: can I install above?

    So I just bought a license to upgrade to workstation 12. Now, I noticed that it is (finally) 64-bit native. However, 11 Workstation is native 32-bit. Can I just install VMware Workstation 12 top like I did the upgrade from 10 to 11? Because the 10 and 11 were native 32-bit.

    The question is moot.
    Upgrade has always meant uninstall the old version, install the new version.
    If you do it yourself, you have more control, but the results will be the same.

    The safest option is: uninstall manually - reboot - check registry for services that have not been removed - if necessary, repair registry - restarts again and then install the new version right after the restart.

    PL indicate how you plan to upgrade. If you are about to upgrade directly on-site using DBUA scripts or migration, the characters will not change as part of the upgrade. The character set can be changed if you create a new 11.2.0.3 empty database and then perform an upgrade via export/import.

    Oracle recommends to use the AL32UTF8 (http://docs.oracle.com/cd/E11882_01/server.112/e25494/create001.htm#ADMIN13343) characters, but if your application does not expect never to use any characters that do not appear in US7ASCII, you can continue to use this game.

  • Remove the old "dump" spfile settings after the upgrade to 11g?

    We have recently upgraded to a development instance from 10g to 11g using dbua. During the upgrade, we have provided a value for diagnosis Destination (diagnostic_dest). However, when I do a "dump of parameter of the show', I see several obsolete parameters like background_dump_dest, user_dump_dest and core_dump_dest. Although filled with places, that we would expect (under "diag"), I had hoped dbua could get rid of these "old" settings I interpreter 'old' to mean "deprecrated."

    1st quarter) I must take action? I've seen several workshops to upgrade - to-11g / slides / tip sheets that recommend the deletion of "old" settings But they never seem to give any details on those who, precisely, to remove. Although I found the syntax (alter system reset < parameter name > scope = spfile sid ='* ') I need additional information on specific settings I should remove.

    Q2) when we went from 9i and 10 g some time ago, I think not that the decisions have been taken to remove settings from 'old', then either. If our current 11g pfile / spfile may have contained superfluous. So what is the best way to review and identify the parameters to delete? I have to do the following:

    Select name, value, isdeprecated of the parameter $ v where isdeprecated = 'TRUE '.

    ... and start from there?

    While it would be nice to have a 'clean' spfile, I didn't much care on superfluous, inert stuff that is not harmful. But I am concerned with settings that could cause unwanted and unexpected behavior or performance problems. Does someone can give a specific example (or examples) settings of 'old' by leaving in place where can cause side effects?

    When upgrading you must first remove all parameters Oracle will not be present. These are usually identified in the documents of upgrade.

    Second, you need to delete probably all parameters that are obsolete and if present ignored. The presence of ignored parameters looks like confusion somewhere down the line.

    Third, if you implement all the new features via database settings, you probably want to remove database settings that apply to the features that your new choice obsolete as you would probably want to remove sga_target and pga_aggregate_target, if you set to 11 g memory_target.

    You can have just a glance in the Upgrade Guide :-)
    http://download.Oracle.com/docs/CD/B28359_01/server.111/b28300/upgrade.htm#BABGAGAE
    If you have not already put your existing databases to the file version of zone 4 (patch 5632264 - TZ V4 file), you must do so before upgrading to Oracle Database 11 g Release 1 (11.1).

    This means: for all SOURCES database releases with the exception of 10.2.0.4 you will need to apply the DST time zone fixes to the definitions of patch in V4 base time zone. with catupgrd.sql or DBUA upgrade will fail with ORA-1722 - if you experience what you have not run utlu111i.sql to check your current database - he would have said to patch time zone before upgrade.

    Hello

    What is the edition of Windows Vista installed on the computer?
    Make sure that you upgrade to the correct version, some versions of Windows cannot be upgraded with the installation disc you are trying to use. For example, you cannot upgrade a 32-bit version of Windows to a 64-bit version, or upgrade a higher edition of Windows like Windows Vista Ultimate Edition, to a lower edition, such as Windows 7 Edition Home Premium. If this is the case, you will need to use the custom during installation option.
    Before you attempt to upgrade, please run the Windows 7 upgrade Advisor:
    http://Windows.Microsoft.com/en-us/Windows/downloads/Upgrade-Advisor
    Also, check if your computer is compatible for Windows 7, using the Compatibility Center:

    Method 1: If the computer is in power saving mode, check if you can wake the computer from this State by moving the mouse or pressing any key on the keyboard.

    Method 2: Change the power to another and check to see if the problem persists
