restore point warranty Vs catdwgrd.sql downgrade for oracle 12 c


I understand that we have two ways to downgrade (assuming that the compatible parameter is not modified) when upgraded us a 11.2.0.3 database for oracle 12 c.

I am curious about the benefits of catdwgrd.sql compared to the guarantees of restore point downgrade. I think that the guaranteed restore point seems very simple

compared to catdwgrd.sql. I also think that oracle brings exactly the database in the same State when we use catdwgrd.sql, while

guaranteed restore point brings back us to the State.

Thank you

  • Ocacle 12 c with SQL navigator for Oracle

    Hi, could someone help me. I recently installed the Oracle 12 c on my laptop. Try to connect the oracle SQL Navigator for oracle database, but could not succeed

    Sometimes, this error will occur if the tnsnames.ora file is corrupted. Can you please check tnsnames.ora and sqlnet.ora with a text editor ordinary for illegal characters (not the one that comes with Navigator because that could make corruption).

    Or simply move the tnsnames.ora that far and try with direct connect. (hostname:port\SID).

  • SQL Query for Oracle DB followed by using vCOPS

    Hi guys,.

    I installed a general SQL adapter to monitor an Oracle database in my environment. But I am not able to make it work there are a lot of problems in writing a SQL Quries. I work with one of the DBA and we are still not able to write the query to the right. Can someone give me an example of a query so that I can test it or tell me how to write the query to Oracle DB. Examples of files that are given under/samples/folder conf in the plug-in does not help us. So if someone has a link or if someone has it please help me with query files.

    Thanks in advance

    fix. the biggest challenge with the SQL adapter is to write the query in such a way the release of product that is easily consumable by vcops and maps directly to RESOURCEKIND and RESOURCENAME in vcops. The result can also be hierarchical for more efficiency, i.e.

  • SQL Loader for Oracle instant client 11

    I have a problem sqlldr.exe running on a machine having Oralce 11.1.0.6 instant client installed. I already copied all the DLL files it says that he needs and the whole repertoire of a machine with installation complete of RDBMS. This is the error I get:

    The add-on only supported for the moment customer is sqlplus, integration of other utilities is not supported. You can just mix DLLs of different software. There are a few documents on workarounds, for example:

    But no guarantee that it works and not support of Oracle.

  • New creation problem with Vista HP restore point

    My laptop, a sony vaio VGN FE-890, developed all of a sudden a group of problems, slowdown, programs responds not, printer won, t etc load.

    I'm doing a system restore but all my restore points went off the menu except for a restore at the present time and date. When I try to create a new restore point it will only ask for a name, and then creates a new restore with the date and the current time point. I need to restore to a week or more in the past. What I am doing wrong?

    If you don't see more of 1 restore point, that's all you have. If each time that you create a new, the previous 'disappears' my first suspicion is that you don't have enough space allocated to store more than 1 restore point. This article tells you how to investigate your system restore benefits:

    http://blogs.TechRepublic.com.com/window-on-Windows/?p=1077&tag=nl.E132

    This article is general information about the system restore:http://www.davescomputertips.com/newsletters/2010/101101.php

    If this isn't the problem, the next thing I see is that you have some sort of automated process of 'cleaning up' configuration 'extra' restore points. This seems to be a remote possibility because most of the cleaning tools are not triggered by the creation of restore point, but I suppose it could be possible.

    There are many utilties of freeware that make the management of restore points a little more friendly that the native windows tools, here is a link to one of them:

    Don't set system restore to monitor other than readers that what is installed on Windows.

    Have you tried to add your account to the list of permissions for the directory of system restore, etc. If this does not work, then try to disable user account control and see if that is the question.
    To disable UAC

    1. Click Startand then click Control Panel. In Control Panel, click user accounts.

    2. In the user accounts window, click user accounts.

    3. In the user accounts tasks window, click turn on UAC enabled or disabled.

    4. If UAC is currently configured in Admin Approval Mode, the user account control message appears. Click continue.

    5. Clear the check box use User Account Control (UAC) to help protect your computer , and then click OK.

    6. Click restart now to apply the changes immediately, or click restart later and close the user accounts tasks window.

    If disable UAC does not help with the creation of a system restore point, try the following:

    (1) put in place a start-up in minimal mode and see if a 3rd party program or software may interfere with the system restore point.

  • Question of RMAN restore points

    Hello

    I'm on the 11.2.0.3 Oracle database. Currently, we have RMAN scripts that make incremental backups and weekly/monthly full daily. My daily script is as below:

    {
     allocate channel t1 type 'sbt_tape' parms 'ENV=(TDPO_usrFILE=/usr/tivoli/tsm/client/oracle/bin64/tdpo.usr)';
     allocate channel t2 type 'sbt_tape' parms 'ENV=(TDPO_usrFILE=/usr/tivoli/tsm/client/oracle/bin64/tdpo.usr)';
     allocate channel t3 type 'sbt_tape' parms 'ENV=(TDPO_usrFILE=/usr/tivoli/tsm/client/oracle/bin64/tdpo.usr)';
     backup format 'prod_dailybackup_%d_%s_%t' incremental level 1 database;
     backup format 'prodarchbackup_%d_%s_%t' archivelog all not backed up 1 times;
     crosscheck backup;
     crosscheck archivelog all;
     delete noprompt obsolete;
     delete noprompt expired backup;
     delete noprompt expired archivelog all;
     report schema;
     release channel t1;
     release channel t2;
     release channel t3;
    }
    

    And the script to backup weekly as below:

    {
     allocate channel t1 type 'sbt_tape' parms 'ENV=(TDPO_usrFILE=/usr/tivoli/tsm/client/oracle/bin64/tdpo.usr)';
     allocate channel t2 type 'sbt_tape' parms 'ENV=(TDPO_usrFILE=/usr/tivoli/tsm/client/oracle/bin64/tdpo.usr)';
     allocate channel t3 type 'sbt_tape' parms 'ENV=(TDPO_usrFILE=/usr/tivoli/tsm/client/oracle/bin64/tdpo.usr)';
     backup incremental level 0 format 'prod_weeklybackup_%d_%s_%t'  database;
     backup format 'prodarchbackup_%d_%s_%t' archivelog all not backed up 1 times;
     release channel t1;
     release channel t2;
     release channel t3;
    }
    

    My two questions are:

    1. can I add a "restore point" for the backup script daily, without the clause "keep until the"?

    2. can I add a restore point whose name is generated dynamically, for weekly backup, for example: weekly_rest_point_13082013, including therefore the current date?

    Concerning

    Dula

    Hello

    1. can I add a "restore point" for the backup script daily, without the clause "keep until the"?

    I think not, is to keep to the required field

    2. can I add a restore point whose name is generated dynamically, for weekly backup, for example: weekly_rest_point_13082013, including therefore the current date?

    Don't you cannot assign the dynamic name in name of the restore point.

    It should be as it is to say

  • Developer equivalent Edition for Oracle?

    I'm a software developer and database which currently specializes in Microsoft SQL Server, but I'd like to be able to offer Oracle to my customers as well.  I use SqlServer MS SQL Server Developer Edition on my laptop, which has all the technical features of SQL Server, but is allowed only for development purposes and is very cheap (under $ 150).

    I took some training for Oracle, but I would get something similar for learning, practice, try things and development on my laptop.  Is there something equivalent available for Oracle developers?  I tried Google this, but that just begins to turn upward of "SQL Developer for Oracle" which I * think * is just the developer GUI and not the DBMS itself. (?)

    If it's important, my laptop is running Windows 7 x 64.  Thank you...

    You can use the version business development for free and download from OTN.

    See the license here: terms of the OTN Developer license

    But if you want to go to production, you will need a permit.

    Do not use XE for development - because it has several limitations - if your customer is going to buy a license.

  • Migration from SQL Server to Oracle database

    I have 2 questions:

    1. we intend to convert our sql server databases oracle OLTP databases. I tried to use SQL Developer to migrate a database of small sql server to oracle (size 5 GB) database. It was fine. When I tried to migrate to a different database (size 90G), it takes too much time. The problem with sql developer is I can not pick and choose tables. 250 paintings, I need to migrate tables abt 80 (the size will be abt 50 G). What is everyone can share their experiences, as appropriate, converting databases of size average sql server for oracle databases? other options?

    2. I intend to convert the sql server ddl to oracle ddl. I have tested bcp out and use sql loader to import the data. Right now I am manually creating the oracle tables sql server tables. I use http://download.oracle.com/docs/cd/E11882_01/gateways.112/e12069/apa.htm#BABCIIDI to convert the code. Are there other ways better to convert sql DDL DDL Oracle Server?

    Thanks in advance

    DDLS must be converted manually. Oracle is not SQL-Server.

    If for example, you have the option of partitioning, you should consider using the partitioning index and when it is possible. Not all tables must be hash tables. Do postpone you creation of segment or not? What type of tablespace? Set yourself free percentages and allows you to manage when the data block is on the free list and how much is reserved in the block of data to update rows in this block?

    There are many considerations to be taken with regard to the physical database design.

    Using BCP and SQL * Loader sound good. SQL * Loader is fast and scalable - use it to load up to 3.6 million lines every 60 seconds. Direct and parallel charges will give the best performance in this regard (assuming that the underlying table structure and use supports this approach).

  • How to restore a significant update to Windows 7 I lost after a restart for an earlier version of the system restore point?

    I am running Windows 7 64-bit Service Pack 1 on a desktop HP Pavilion Elite HPE-350 t. Recently, a malfunction of Windows at startup caused my father reboot the system to a previous system restore point. (He says it was one of several options at startup.) Everything seems to work fine now except that I seem to have lost a critical update Windows downloaded after the restore point, Windows Update Agent 7.6.7600.256. Still, there are in my Windows update history and is listed as "installed successfully", but when I check my updates installed, it is absent. Also, when I try to search for updates installed, I get a message indicating that Windows is up-to-date. I can't uninstall the update and re - install because it is missing from my list of installed updates. So I guess that the re-start to a previous system restore point has put this important WIndows update in limbo. How can ensure me that this update is installed correctly and working properly?
