3.1 upgrade with multiple databases

We have 3 Oracle databases (10g) with APEX on a server. Two databases run with APEX 3.0 & one still runs with APEX 2.
I want to upgrade to APEX 3.1. I ran the apexins script against the APEX 2 database, but now I'm faced with the step of copying the new 3.1 images over the old image file. My questions is what will happen to my existing 3.0 APEX installations if I copy the new image files?

Hello,
>> For some reason, I was able to run both APEX 2 & APEX 3 on the same server,…
By “on the same server” you probably mean the same HTTP server. This is a supported configuration. A single OHS can support more than one APEX instance, and they don’t have to be the same version. A single database can’t support more than one version of APEX.
>> … but I can't figure out why except to say that the 2.0 and 3.0 images were somehow compatiable …
New ‘images’ directory, for a newer version, usually add features – icons, themes, templates etc. – to the directory, and don’t delete old stuff. Even the built-in JavaScript library maintains backward compatibility. That means that early version of APEX, like 2.x, can find anything it needs in an ‘images’ directory from 3.x version.
>> But it looks to me like the 3.0 & 3.1 images are incompatible.
I’m not sure what you mean by compatible, but the 3.1 version of ‘images’ is quite different – content and structure wise - from the 3.1 version. Still, application that was built using 3.0 should run with the 3.1 ‘images’ version. The reverse direction is, of course, not possible.

  • How to investigate high io in a RAC with multiple databases?

    how to investigate high io in a RAC with multiple databases?

    RAC is saying that a single server lacks the processing capacity needed for databaseA. So additional databaseA instances on additional servers are needed in  order to meet the processing demands for databaseA. Thus RAC is required.
    Multiple databases on a single server says that the server has spare processing capacity and that it can not only deal with databaseA processing demands, but also with the processing load of databaseB.
    So how does your statement about running multiple database RAC instances on the same RAC server node, make sense? And does your I/O issue not immediately point to the fact that no, RAC server1 cannot deal with the I/O resources required by both databaseA and databaseB?
    After all, how is I/O scaled on RAC? How is ANYTHING scaled on RAC? By adding more databases to a RAC server node? Of course NOT!!
    RAC scales by adding more servers (with a new database instance each) to a physical database in order to scale processing capacity and I/O. By adding more I/O channels to access the SAN/shared storage. By adding more CPUs to increase processing capacity.
    Bluntly put - multiple RAC database instances on a single RAC server node is kind of an idiotic approach to scalability in my view....

  • Can we link one application instance with multiple databases ?

    We have R12.1.1 and db is 11.1.0.7 on redhat 5.3 ( 64 bit).
    Can we link one application instance ( apps / , inst / ) with multiple database ( db / ),
    is this possible ?
    if yes how ?

    No. You cant link application tier with more than one database.

  • RAC with multiple databases

    hi,
    we are evaluating a design for the configuration of 3 databases in 10g RAC in linux
    Available HW: 2 servers each with 32 gb ram
    No of databases need to be configured :3
    what would be the effective configuration?
    the options we think are,
    1) One 2 Node RAC with 3 databases or
    2) Three 2 Node RAC each with 1 database each
    what would be the licencing cost in different options
    please help
    tia,

    hi,
    sorry, am new to RAC.
    heard about one implementation wherein with a h/w of 2 servers,
    1) 2 node cluster for one database
    2) single node cluster for the second database in one of the servers.
    is it possible to configure multiple clusters on the same machines?
    here in our case, we have 3 databases that need to part of RAC configuration.A single node cluster? A "cluster" implies two or more servers.
    If you have two servers, you can create two node cluster for any number of RAC database(s).
    Also you can create stand-alone database(s) on either server.
    If you use VM, you can cluster as many VM machines as you have configured.

  • Working with multiple databases

    Suppose I have a large project that follows the formal "SDLC" model for software development; it has various stages, environments, development, integration testing, system testing, UAT, etc. Each of these environments is on its own dedicated Oracle database.
    An query-only Apex application is built as a testing aid for the various environments to quickly see reports, test data conditions, etc. This application is deployed to all the environments.
    With other web development technologies (PHP, ASP/.NET, etc) which live outside Oracle and access Oracle using a userid/connect string. If some aspect of the application needs to be changed, it is done in 1 place (the application) and the new/modified functionality is available for use against all the enviroments (just change the connect string in the URL or some config file to access different environments).
    With Apex, the change to the application has to be done in all the 4 environments. This seems like a case where the Apex architecture (all app metadata in Oracle) is a disadvantage.
    Comments? Thanks

    That would be that case if you are only talking about only moving through the SDLC with your database changes yes? In many cases, you make changes both to the underlying database structure/code and the application (PHP, ASP, etc) so your application would "follow" your database code wouldn't it?

  • Upgrading with multiple lines

    My phone (primary line) is available for an upgrade in October, but my wife's (secondary line) isn't until April. We're both grandfathered with the unlimited data plans.  If I upgrade mine in October, the family plan will convert to the tiered data plan.  What does this do for my wife's phone?  Will she continue to have unlimited data until she upgrades, or will she be forced into the tiered system?  Is there a way that she can early upgrade as well, without having to pay full price?

    As long as you go into the tiered data when you upgrade in October your wife will be able to keep her unlimited until she upgrades. If you want to upgrade your wife's phone in October as well you could pay the ETF which would probably be about $100ish with how long you have been on contract. You also may be able to get the upgrade in October if you've been with Verizon long enough but that is no guarantee.

  • Single Weblogic Process with multiple databases

    You have to use XA Driver which supports Distributed Transactions. This is
    supported from 6.0.
    Weblogic provides Type2 XA driver for Orcale and Oracle's Thin Driver

  • Hdd upgrade with multiple partitions

    I currently have a 250gb hdd with lion and a bootcamp partition of windows 7.
    I would like to upgrade my hdd because I am running out of room.
    I understand that I could most likely back up the entire drive to an external, then install the new hdd and reinstall the backed up data. That should put both partitions the way they were onto the new hdd. At least that is what I think.
    But I would like to have a bigger partition for windows and I am unsure how I would do this correctly. I don't know if reinstalling the backed up data to the new drive, deleting the bootcamp partition, then creating a new partition and reinstalling my same windows would work. Would I even be able to install windows a second time on the same computer without having to buy another key?
    Final thoughts:
         1. Will backing up the entire drive to an external, then install the new hdd and reinstall the backed up data put both partitions the way they were onto the          new hdd?
              a. Will the OSX partition get all the new space?
         2. How do I get a bigger windows partition on the new hdd, while keeping all of my existing windows content?
    Thank You for the help

    Use Windows software to backup your Windows system. When you setup your new Windows partition on the new hard drive reinstall Windows then restore your backup from the backup drive you use for Windows. You don't need another key as long as you don't have the same key active on more than one computer.
    Similarly, for OS X backup your current system to an OS X backup drive. See the following:
    How to replace or upgrade a drive in a laptop
    Step One: Repair the Hard Drive and Permissions
    Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Installer menu (Utilities menu for Tiger, Leopard or Snow Leopard.) 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.
    If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
    Step Two: Remove the old drive and install the new drive.  Place the old drive in an external USB enclosure.  You can buy one at OWC who is also a good vendor for drives.
    Step Three: Boot from the external drive.  Restart the computer and after the chime press and hold down the OPTION key until the boot manager appears.  Select the icon for the external drive then click on the downward pointing arrow button.
    Step Four: New Hard Drive Preparation
    1. Open Disk Utility in your Utilities folder.
    2. After DU loads select your new hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area.  If it does not say "Verified" then the drive is failing or has failed and will need replacing.  Otherwise, click on the Partition tab in the DU main window.
    3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to GUID  then click on the OK button. Click on the Partition button and wait until the process has completed.
    4. Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
    5. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, check the button for Zero Data and click on OK to return to the Erase window.
    6. Click on the Erase button. The format process can take up to several hours depending upon the drive size.
    Step Five: Clone the old drive to the new drive
    1. Open Disk Utility from the Utilities folder.
    2. Select the destination volume from the left side list.
    3. Click on the Restore tab in the DU main window.
    4. Check the box labeled Erase destination.
    5. Select the destination volume from the left side list and drag it to the Destination entry field.
    6. Select the source volume from the left side list and drag it to the Source entry field.
    7. Double-check you got it right, then click on the Restore button.
    Destination means the new internal drive. Source means the old external drive.
    Step Six: Open the Startup Disk preferences and select the new internal volume.  Click on the Restart button.  You should boot from the new drive.  Eject the external drive and disconnect it from the computer.

    The PL/SQL code grabs the "selected" database link from :LOC and parses the SQL QUERY you want to execute replacing some token (like [LINK]) with '@DBNAME'.
    Lets say your SQL statement is coded like this:
    mySQL := 'SELECT cust_name FROM working_lines[LINK] where phone_no = :Phone;'
    Then all you would have to do to replace '[LINK]' with the proper DB alias would be:
    mySQL := REPLACE(mySQL, '[LINK]', '@'||:LOC);
    and then return the new SQL ...
    if :LOC has something like 'V10GPROD' your SQL would look like :
    SELECT cust_name FROM working_lines@V10GPROD where phone_no = :Phone;
    The beauty of this is that you can also include a "null" option that means the select statement will be executed on THIS database...

  • Possible to sync multiple phones with multiple database?

    Forgive me if this has been covered, if so please point me to the right thread...
    Ok, I have two phones and one pda. I'd like to keep different database (and yet be able to selective choose data from one database to another). Is this possible?
    The reason for this setup is that I have one USA phone and one Taiwan phone and one PDA (with less dialed contacts). Obiviously, when I'm in Taiwan, I don't need any USA contacts in my Taiwan phones. (I know phones nowadays have enough memory to fit 100s of contacts, but I don't wan to scroll through a bunch of contacts that I don't need.)
    Any solution to this using iSync?
    Thanks!

    It depends entirely upon your mobile handset. Generally speaking, you can choose to synchronize by Address Book group, and not synchronize your entire Address Book database with each device. This is certainly supported by iSync for Palm devices.
    To determine the options for each handset and your PDA, select each one in iSync to drop down a configuration dialog specific to that device.

  • RMAN with multiple databases

    Hi,
    I need to define a mechanism with RMAN to backuptwo databases where information is copied from one to another by using Oracle Data Integrator CDC.
    How can I backup and recover both databases and it still sync?
    Thanks
    Homero

    Yes.
    And that is why I said "If you create distributed transactions between two Oracle databases, a Global SCN is synchronised".
    YOU CREATE distributed transactions.
    Test it out.
    Put two dummy tables in each database.
    Have a database link configured.
    Run some distributed transactions.
    Check the SCNs.

    nother pool: MultiTransactionTestHi. You can't domultiple DBMSes in one transaction unless you use an XA driver and
    an XA transaction. Your workarounds are:
    1 - Use an XA driver, datasource, and tx
    2 - If you're just reading, you can use non-transactional datasources. Do make sure you
    always close your connections...

  • ASM with multiple databases

    I need to create lots of databases on a single server for development/testing work but am not sure if I should create a single ASM instance to serve all of them, or one ASM instance per database. I need all databases to use different disk groups anyway, so is there a "best" way?
    Would this change if the databases are for production use?

    >>>>I should create a single ASM instance to serve all of them, or one ASM instance per database.
    You can have only one ASM instance per server..
    I need all databases to use different disk groups anyway, so is there a "best" way?
    You can create one ASM instance and then create different Diskgroups and have each instance use a different diskgroup.
