Database Upgrade In Place -- 9i to 10g

Does the size of the database matter when upgrading from one Release to another.
CASE I
Size of Database, datafiles etc. -> 1TB
CASE 2
Size of Database, datafiles etc. -> 200 MB
How much will the databases differ when they are upgraded in place, would the second database be 5 times slower or will it be approximately the same time to upgrade the database from one release to another?
Thanks

Hi Nicolas,
Thanks for the reply.
By inplace I meant methods similar to DBUA or startup upgrade;
The question I have is does it matter significantly as far as time taken to upgrade is concerned, if your database is big or if your database is tiny.
but by this method the time to upgrade the databases will not far.I am of the same opinion as you that time to upgrade a mammoth database versus a small database will not vary significantly. Any other experts on this.
Thanks

  • Forms HOST command no longer works after database upgrade from 10g to 11g

    Hi,
    After upgrading the database 10g to 11g the forms HOST command no longer works on Unix server. The form used to work fine prior the upgrade. I read all the threads I could find and did not see any solutions. Adding PATH and LD_LIBRARY_PATH does not work because it does not even run a basic shell script. (I saw this solution, adding PATH and LD_LIBRARY_PATH, in many questions / threads).
    1. I wouldn't expect the database upgrade to be an issue, but it is the only change we had.
    2. Note, 11g is Oracle Fusion Middleware which is quite a bit different than 10g.
    I even tried the most basic commands like "echo" which is a build-in Unix command and there is no directory for it (ie. no /usr/bin - so variable PATH is irrelvent). i.e HOST('echo hi'); and HOST('echo "hi" '); and even HOST ('echo hi > /my_file.txt'); all returns FORMS_FAILURE (actually the if is IF FORM_SUCCESS THEN ... else ... and the else part always runs now - whereas it didn't before.).
    Or basic commands like /usr/bin/ls as in HOST(/usr/bin/ls). At that point I was just testing the Unix command would return FORM_SUCCESS even though I could not see the results (because they weren't writing to a log file). Notice that I'm using the direct path /usr/bin so no Unix environment variables were needed.
    The form does use webutil but that part works. For example, we have webutil_file_transfer( ....) The file shows up on the application server and in the expected directory.
    Here's the main goal. Upload a file from clients local PC to the datebase server. The form uploads the file to the Application server, then we have a Unix script to scp (secure copy) the file from the application server to the database server. IF webutil, or any other Oracle functions could put the file on the database server that would be better. But, I don't know of any procedures that do that - or would have done it cleanly (i.e. storing to database and write back to server and then using a blob etc. )
    Anyway, I was hoping someone would help with either of these.
    1) Get the HOST command to work. - If we can get that to work then I wouldn't need any more help. We can just call the already existing Unix script to copy the file from the application server to the database.
    2) OR be able to upload directly to the database server - wanted to do that originally
    Any help would be appreciated

    Solution for those interested and for anyone else searching this forum for a solution
    I found this on My Oracle Support:
    <h3>Host Command from Forms Not Working in 11g in Sun Solaris Sparc OS [ID 1157346.1]</h3>
    Applies To: Oracle Forms - Version 11.1.1.1.0 and later
    Sun SPARC Sun OS
    Symptoms:
    When trying to execute a Shell script or any OS command using the host() Built-in from Forms 11g, the host()command is not getting executed. The same functionality works on other operating systems and in previous versions like 10gR2.
    Steps to be followed:
    1) Take a backup and edit the $DOMAIN_HOME/config/fmwconfig/servers/WLS_FORMS/applications/formsapp_11.1.1/config/default.env or any custom environment file.
    2) Locate the following environment variable:
    LD_PRELOAD=/ora10gas/app/11.1.0/Middleware/as_1/jdk/jre/lib/sparcv9/libjsig.so
    3) Comment out this variable. After the changes, it will look like the following:
    #LD_PRELOAD=/ora10gas/app/11.1.0/Middleware/as_1/jdk/jre/lib/sparcv9/libjsig.so
    3) a) Instead of LD_PRELOAD, kindly use LD_PRELOAD_64 as given below :
    LD_PRELOAD_64=/ora10gas/app/11.1.0/Middleware/as_1/jdk/jre/lib/sparcv9/libjsig.so
    (This makes HOST AND RUN_REPORT_OBJECT work fine).
    4) Save the file and execute your forms. The Host() built-in will work as expected
    The LD_PRELOAD setting in default.env is only required for the working of signal chaining facility in JVM version 1.5 and later. If you are not using theSignal chaining facility, this variable is not required. For more information, refer to the following documentation

  • 11.5.10.2 12.1.1 and 10g 11g database upgrade at same time

    I have just started an 11.5.10.2 > 12.1.1 upgrade and have created a project in MWIZ 2.15 for it.
    I would also like to upgrade the 10.2.0.2 database to 11.1.0.7 as part of the same upgrade and create an MWIZ project for that.
    I have a couple of questions that the MWIZ FAQ does not address:
    1. At what point in the 11.5.10.2 > 12.1.1 upgrade should I do the database upgrade?
    MWIZ has two points when it can be done based on apps/database versions. One is at the end of the 'Prep for Upgrade' category and the other is during the 'Upg to Rel 12.1.1' category. The MWIZ step notes cover upgrading to the latest 10g or 11g patch version but not upgrading from 10g to 11g so I am unsure which category to go for.
    2. When I create the database upgrade project which 'Destination Version' should I choose?
    The two options are 'RDBMS 11.1 and E-Business Suite 11.5' and 'RDBMS 11.1 and E-Business Suite 12'.
    As I haven't upgraded to R12 yet and am still at the pre-upgrade stage should I pick 11.5? Or should I go with R12 because I am upgrading Apps and the database at the same time?
    Any help and advice gratefully received.
    Thanks

    Answer to above question not required now as:
    Having read the 24th December update of note 761570.1 - 'Database Preparation Guidelines for an Oracle E-Business Suite Release 12.1.1 Upgrade' I have decided to upgrade the database to 11.2.0.x by following the Path C option.
    Unfortunately as the 11.2.0.x upgrade isn't covered by MWIZ yet I will have to follow the manual steps.

    As part of the upgrade, you might research how new Oracle 11g features can help your system run better.
    Your upgraded system can effectively start using extended statistics, a very powerful new 11g feature, immediately after the upgrade. I have a detailed blog post on how to do this with OEM - http://iiotzov.wordpress.com/2011/11/01/get-the-max-of-oracle-11gr2-right-from-the-start-create-relevant-extended-statistics-as-a-part-of-the-upgrade

  • Upgrade 6.0 repository to 10g

    How's the best way to accomplish the repository upgrade ?
    I also have a 9i repository into which the 6.0 needs to be merged into at sometime...
    Thanks

    It is easy to see what version of the repository you have. Start any of the Designer client tools, connect to your repository, and choose the "Help" menu. Then choose "About". The Component labeled "Configuration" will be your Repository version. For a more detailed look, press the "System Info..." button. But if it is accessible with a 9i client, it is probably the version of the repository that goes with a 9i client - client and repository are very closely coupled - only the RAU can usually connect to a repository that doesn't match the client.
    If you use RAU from 9i to look at your current repository, if the "Upgrade" button is grayed out, then RAU believes that your current repository is in fact the correct version for your 9i client. If so, do yourself a favor: Use "Check Requirements" and make sure that the EXECUTE_EXPORT parameter is pointed at the "exp" utility for the database version in which the repository is installed. If you don't have client software for this database, get it and install it in a separate Oracle Home. Then use the "Export" button in RAU to back up your repository.
    If you connect to the current repository with your 10g client's RAU, that "Upgrade" button should be active, meaning that RAU is ready and able to upgrade that repository to the version that is compatible with your 10g client. Don't do that yet. First, you want to make a good backup of your current repository.
    Now you have a decision to make. You say that you made a new repository instance on a 10g database. I don't think you really want or need a new repository. What you really want to do is upgrade your current repository. So I would go ahead and drop your new repository owner with the "CASCADE" option, to give yourself a clean slate. Now do you want to upgrade in place, or do you really want to move your repository to a new database? If you want to move to a new database, I would export the repository owner schema with "exp" outside of Designer using the "exp" version that matches the original database, then import it using the "imp" version that goes with the new database.
    There is one problem that you may encounter when you do this. Later versions of the repository have four collection types created with the "CREATE TYPE" command - JR_NUM_LIST, JR_STR_LIST, SDD_ACC_PRIV_LIST, and SDD_SYS_PRIV_LIST. Object types have an associated object ID, that some versions of "exp" do not export properly. On import, the objects get created with a new object ID, yet when the data is imported, Oracle won't import it because the new object ID doesn't match the ID of the data being imported. The solution is to pre-create the schema for your repository owner, and pre-create these objects using the OID clause with the object ids that they had in the old repository. Then import with the "ignore errors" option.
    Finally, connect to your repository with the 10g version of RAU and press the Upgrade button. Good luck, and let us know how it turns out.

  • Upgrading rman 9i catalog to 10g catalog.

    Hi,
    I need to know the typical steps to upgrade the rman catalog from 9i to oracle oracle 10g. We have already 9i db's registered with 9i catalog and 10g db's are there which we will register with the upgraded 10g catalog.
    Kindly provide links and also summarise here the typical steps involved.
    Thanks in advance for all the help !!

    Depends. If you want to do an in-place upgrade, then upgrade the database to at least the highest 10g database that will be connecting. For example, if the highest 10g version you have is 10.2.0.1, then go to at least 10.2.0.1. I have been running 10.2.0.3 without any issues.
    After upgrading the database, login to the rman catalog using the same ORACLE_HOME as the database, and run:
    upgrade catalog;
    That's it. No bells, no whistles. The docs are very clear on this and it's not a huge ordeal.
    Or, you can export/import to a new database, and run 'upgrade catalog' on it.

  • Database upgrade concepts

    Hello,
    Please help me understand the complete scenario on database upgrade, here is what I know:
    - We have Oracle 9i database installed
    - We install new Oracle 10g Database on same machine with different SID
    - We upgrade Oracle 9i database using DBUA of Oracle 10g
    - The Oracle 9i database is upgraded to Oracle 10g Database and we dont need to move our data from old database to any new place
    1. What happens to the new Oracle 10g installation ? Should we remove the installation ?
    2. Will the SID of old home be changed or will it be the same?
    I read many docs, all of them explain the method to upgrade, but not the complete scenario.
    Thanks in advance :)

    - We have Oracle 9i database installedOK
    - We install new Oracle 10g Database on same machine
    with different SIDNo. A SID is associated with a database. if you're going to use the DBUA, you'd just want to install the 10g software into a separate Oracle Home. You would not want to create a new database.
    - We upgrade Oracle 9i database using DBUA of Oracle
    10gOK
    - The Oracle 9i database is upgraded to Oracle 10g
    Database and we dont need to move our data from old
    database to any new placeCorrect
    1. What happens to the new Oracle 10g installation ?
    Should we remove the installation ?No. The 10g Oracle Home you just created is the new Oracle Home for your database.
    2. Will the SID of old home be changed or will it be
    the same?I'm not sure what you're asking here, but I suspect the question is moot based on the corrections above.
    Of course, I assume that you'll be upgrading your dev & test databases long before you try to upgrade prod so you'll have plenty of practice and plenty of time to make sure that everything is working after the upgrade as you'd expect...

  • Database Upgrade Agent not working for upgrading Oracle 9i DB to Oracle 10i

    Hi All,
    Presently I have completed my Oracle 10i installation on Solaris Server but I am facing an issue during the upgrade process of Oracle 9i to 10g. Whenever I try to upgrade the 9i databases to 10g using DBUA(Database Upgrade assistant) I am facing an issue that Data base not running from oracle home or pfile not found. The exact error message says:-
    The upgrade assistant failed in bringing up the database XIPCOTS. Oracle Home /opt/apps/home/oracle9i/product/releases/92/92 obtained from file /var/opt/oracle/oratab was used to connect to the database. Either the database is not running from Oracle Home /opt/apps/home/oracle9i/product/releases/92/92 or the correct Initialisation parameter file (pfile) was not found. To start the database , Oracle needs the pfile. Provide the full path name of the init file for the database XIPCOTS.
    In reality the XIPCOTS database is running fine in Oracle 9i and we can connect it using PL/SQL developer in windows.I have also provided the path of pfile but it is still not accepting the same.
    Path of pfile I provided :- /XIP/ofaroot/XIPCOTS/pfile/initXIPCOTS.ora
    Any help or suggestions would be greately appreciated.
    Our both Oracle 9i and 10g are installed on same Solaris server where solaris version is 9
    Installation path for 9i :- /opt/apps/home/oracle9i/product/releases/92/92
    Installation path for 10g :- /opt/apps/home/oracle/product/releases/10201
    Oracle 9i version :- 9.2.0.7
    Oracle 10g version :- 10.2.01
    Thanks in advance.
    Best Regards,
    Gourav Banerjee

    Can you please mention the specific folder name under oracle home where we need to put this pfile because there are two folder dbs and ds I have allready tried putting it inside dbs its not working. And my home path is correct I hope and is set for oracle 9i directories in the .oraenv file do we need to set it for oracle 10g before the DBUA upgrade.

    2. Do we need to take any DB backup before the upgrade?
    3. How will the OBIEE windows box ODBC connect to the upgraded 11 g instance? Will the version 10 driver work to connect to version 11 databases?
    4. We have Informatica,DAC in the existing instance. Will the DB upgrade have any impact on them?
    Could anyone please share their experience/thoughts on the above like the steps to perform the upgrade.

    I do have quick questions regarding the upgrade.
    1. When we upgrade the Database to version 11, do we need to update the client also? What is Oracle recommendation?Just 11g upgrade will include all cient/Server tools on you Linux Box. On client side its recommended to upgrade client version 11.1.0.7.
    Please refer MOS tech note:
    *Oracle 10g Client Connecting To Oracle 11g Database Gets ORA-01017 invalid username/password [ID 888432.1]*
    2. Do we need to take any DB backup before the upgrade?Yes, perform full cold backup of Database as well as 10G $ORACLE_HOME binaries including inventories.
    3. How will the OBIEE windows box ODBC connect to the upgraded 11 g instance? Will the version 10 driver work to connect to version 11 databases?AFAIK, it should work. What is the version of OBIEE?
    4. We have Informatica,DAC in the existing instance. Will the DB upgrade have any impact on them?Again AFAIK, there should not be any effect. I would recommend you to log a S.R and verify the same from support.

  • Upgrade Oracle Text 8i to 10g

    Hi,
    I have to upgrade a database 8i in Sun to Linux 10g, I know that I have to upgrade via export/import but I don't know how to migrate Oracle text.
    In the new server I have installed oracle text, but I don't know if i need to make and export/import of CTXSYS user or if I need to recreate all indexes in the new database ...
    Can anyone help me please!?
    Thanks.

    Hi,
    it safer to make CTXSYS user in 10g with 10g options, then export and import tables for indexes, then make new indexes. But you have to test it and find if Oracle Text work the same way for you application as on 8i.
