Migration of data from the old platform to the new primary database, need advice.

I have physical standby facility and everything works now.

Next weekend, we will do the actual migration of the old platform to the new environment.

I have several issues of concern.

Migration will go to the primary database. I'll have to remove patterns and inside expdp dmp.

While I do all those, what data base waiting? should I disable it again apply?

What other concerns and precautions I need to take before I have to remove all data from primary school and do a migration?

Thank you in advance.

Hello;

My main concern would be the FRA (assuming you use it).

By doing all that generates a ton of archives, you have to worry about the space on both sides.

I would consider increasing my FRA on both sides.

I would not disable the recovery, but I look very close and be willing to adjust my space as needed.

As long as you don't miss space you should be fine. I had once a backup log files more than 250, and it took about 15 minutes to catch up.

Have a little prepared scripts in advance if you can increase the space or delete archive applied and it should be fine.

I also opened at least two terminals on the primary and Standby. Everyone look at space and the other to execute all what you need to adjust the space.

The rest is common sense, first do the smaller drawing if you have an idea what to expect. Decaying etc. as much as possible.

Best regards

I have a shell script called 'quickcheck.sh' (use a separate but .env file it will send information vital back)

With a little work, you can do this in something that makes it easy to keep an eye on things.

#!/bin/bash
####################################################################
#

if [ "$1" ]
then DBNAME=$1
else
echo "basename $0 : Syntax error : use . quickcheck  "
exit 1
fi

#
# Set the Environmental variable for the instance
#
. /u01/app/oracle/dba_tool/env/${DBNAME}.env

and then a SQL file called quickaudit:

  • migration of data from the Office of windows 7 2007

    Hello

I sold my existing iMac and will have to ship power off before receiving the new unit, ergo, I won't be able to use the method of transfer of my data from the old to the new Mac.

    Accordingly, I am looking help form to advise me how can I do to preserve my existing Mac data so that I can install on the new Mac. In addition, how to delete all my data from the old Mac but preserve the OS X (El Capitan) and relevant applications.

    All of the advice and recommendations will be greatly appreciated

    2. you need to remove El Capitan of the old Mac before send you it off and return it to the most recent of its original operating system or 10.6.8.

    I bought an iPhone 6s and want to transfer the data from my old iPhone 4S with iTunes but it says "the"iPhone"iPhone cannot be used because it requires a newer version of iTunes. Go to www.itunes.com to download the latest version of iTunes. "

    Most likely, what you found, is that the iTunes version is the latest available for your operating system.

    The latest version of iTunes is 12.4.3.  This version requires at least OS X 10.8.5 or later version, or Windows 7 or later version.

    If your iTunes version is earlier than 12.4.3, it will probably not recognize your 6s performance iPhone iOS 9.

    If you do not have the required operating system, get first.  Then download from iTunes

  • New iPad: restore the data from the old iPad, but...

    I got a new iPad. I have already backed up my old iPad to iTunes and wanted to put in place the new iPad to restore this backup data. BUT when I connected to iTunes, I've learned that I have to update the operating system first. He wouldn't let me NOT restore from backup! I had to set up as a new iPad.

    So, I did the installation of the new operating system. But I have a lot of applications and data from the old iPad I want on the new iPad. How can I quickly transfer these data? I have found no method to restore the backup of the old iPad now since. Frustrated!

  • importing data from the old system to the new system, key to the raw16 column

    Hi, experts,

    now I have a new system, the design of the system is to use raw (16) column as the key column in all tables of database.
    of course, when the new system goes live (in production), new records of transactions are written to the new database system.
    When the new system inserts new records, it manages itself to avoid any conflict of the raw key column value (16)


    Now, I'm dealing with this problem:

    I need to import data from the old system to the new system, I use sys_guid() to fill the column raw (16) into the new database system.
    How can I avoid conflicts of raw column value (16) between the old system data and the new data of database system?

    the sql code I write is very simple:

    insert into new_sys_table_a (key_column_raw_16,...,...)
    Select sys_guid(), old_sys_col_a, old_sys_col_b
    of old_sys_table_a; 
    insert into new_sys_table_a (key_column_raw_16, col1, col2 )
select key_column_raw_16, col1, col2
from old_sys_table_a;

  • Migration of data from Thunderbird problems

    Hello

    I'm migrating to a new computer. I read the support pages that describe how to migrate a profile Thunderbird from one computer to the other. However, I'm having trouble. After that I copied my profile data to the new location, Thunderbird can see my account information (email address, the server settings, etc.), but it does not show the files and electronic mail that were in my old PC. I am sure that I saved the correct data. If anyone has encountered this before? Any ideas?

    Thank you
    Greg

    Thanks for the suggestion Gnospen. It appeared that everything was there, but it is possible that something in my backup was corrupted. I copied everything from the computer source again, and it works now. I'm not sure what it was, but everything seems to be good now. Thanks again!

  • Remove data from the HD Server?

    I've recently updated my OS to 10.12 Sierra and went to install Server.app. However, when trying to install Mac OS Server, I received the following message:

    "This the server version does not support upgrading the server from data on this volume. To upgrade your database server, you need to install an older version of the server and OS X."

    ***? In what universe would be an acceptable solution? Now, the fact is that I probably had installed Server.app before on a very old version of Mac OS (not sure which) and just never bothered to upgrade during the last major revision of OS X or more.

    What that is, how can I get rid of these old "data server" so I can install a new copy? Thank you.

    Wondering how to remove the data from the server that you had before the upgrade to Sierra? If so, delete the folder/Library/Server and the.app to / applications. Then go to the App Store and buy the latest version of the server. I'm guessing that your last purchase server had Yosemite and that's why try to install the server to the App Store / Shopping does not work. I did purchase the server from Yosemite.
