Updating of the database

Hi gurus,

(1) when we say the updating of the database, we need to remove the database and clone again with the last backups rman.

(2) whereas cloning not set us the id of database also. If we do not then set what happens. in fact, what is the importance of id database parameter.

Please, help me to be clear in this.

Thank you very much...

(1) RMAN is physical backup. So delete the database that should be cloned and generate the backups

(2) there are several ways to clone, if using DUAL control, you should not use DBID.

We might think of the connection string:

target: the new database which is getting cloned
Catalog: catalog database--> that stores all backups of your company

RMAN target / catalogue /@.

RMAN > set dbid ---> to retrieve the details of data source catalog database backup. RMAN backups in catalog
database are identified by the DBID

  • Planning level 11.1.2.1 in 11.1.2.3.5 - updating of the database is not updated every custom on some Member attributes

    Us are currently working on improving our environment to 11.1.2.1 11.1.2.3.5, but have you encountered a problem with one of our applications, and only on one of the cubes in the application. When we perform a refresh of the planning database, it initially stripped of some members of the attributes, custom and is now refusing (Finally, not directly) to update on that specific cube. The other cubes in the same application, I can see the custom attributes, update correctly.

    The cube itself is not locked on the side of essbase, prevents the updates and the updating of the database of planning indicates he managed. I spent reviewing the essbase application log and planning0 journal, noting none of which seems to indicate a problem with the refresh or out of the ordinary.

    I am able to edit the cube directly via EAS and on the updating of the database, the changes are deleted (if I add an attribute) or the Member is restored (if I remove the Member), but still, no custom attributes.

    It is unfortunately the case at some 700 members of 5,000 members in one of our dimensions and only in a cube so that a single application, but we hit an obstacle for what might be the cause. What is happening in the our QA Dev environments, but I expect that since one is one migration on the other. Step moved to production yet because this (among a few other things) continues our implementation.

    If anyone can lend a thought on what could be the cause or the paths to understand where we can't look to fix this? I definitely appreciate all the help that can be done.

    Thank you

    Jonathan

    A solution to the problem, but not sure about the cause. By deletng the cube that has problems and performing a database update subsequently, we are now able to see the cube with the appropriate attributes. It would seem that we had problems with our cube Essbase itself rather than on the side of planning.

    My suspicion is that it might have been caused by our Essbase upgrade are out of sync from the upgrade of planning during the updating of the original database after the start of the process to upgrade (11.1.2.3.5 for planning vs 11.1.2.3 for Essbase). While I am not sure of the cause, I am sure the solution so feeling good go ahead now.

    John - I appreciate all the help and insight along the way, as it has helped us reach this point of the solution.

    Thank you

  • User passwords do not work at the level of the application after updating of the database

    Hello

    Working on the updating of the database user passwords do not work for front end users but the same passwords work at the db level.

    We backup before refresh and restraint after the update, but if the user tries to connect to db, they receive the error invalid password/username.

    but passwords are working at the level of the DB if reset us the password then it works fine, but we cannot do this for all users of all time. can someone share the knowledge or solution for this problem.

    Thank you

    Do you mean that you update the column SPARE4 of $ USER (which is a table, not a view)? I don't think it will work, because the password is salted with a random string that will be different in the two databases. It might work if you return to the use of passwords for 10g, which are salty with the user name. See here, the 10 GB hash stored in the PASSWORD column is the same in the two databases, but the 11g in SPARE4 hash is different:

  • What is the updating of the database?

    Hi all...

    Can someone tell me what exactly the average refresh databases in oracle?

    Thanks in advance...

    jgarry, you are quite right about that.

    An update of the database for a developer could mean just refresh the schema to use in the development database, but NOT patterns of the user.

    An update of the database to a tester could mean to update all application schemas, but certainly NOT the patterns of the user.

    An update of the database to a manager might mean updating the entire database of production, including patterns of the user.

    Most of the cases, an update of the database will probably only see the application schemas they use and not the user patterns.

    In these cases, the use of import and export is the most common method to make the update, although transportable tablespaces multiply for this purpose, but also of the flashback database for testing purposes (or even Real Application Testing - which uses flashbacks).

    In some cases, a test database will need to be completely refreshed with RMAN.

    I hope this helps.

  • Cannot answer your request because the updating of the database

    I created a user in Services shared and then assigned to a group. After that, I went to the workspace in the ahead mode to manage security filters, the user does not appear and when I try to "create" an existing user, an error appears:

    I do not turn any updating in the database and my EAS shows nothing. What could happen? It's Hyperion Planning 11.1.1.3

    Kind regards

    If an update of the planning is certainly not executed then maybe there is still a lock to indicate that an update is running, you can try to run the utility hspunlockapp - unlocking Applications

  • What is the exact difference between cloning the database and updating of the database?

    Hello

    Can someone like me precisely the difference between cloning the database and updating of the database?

    I have some conflicts in these topics.

    Thank you
    Rajesh

    Discounting is what he says, "Refresh". You have a main site which would always have the data inserted into it. There is another site that would stay somewhere else. This site needs to be updated with the main site. It must be the export of primary, push the site high school and done!

  • Updating of the database of Smartview?

    Is there a way to update the database of Smartview? If it is possible, I thought that it would be able to be done via a connection to planning.

    The answer is that it can be updated to the Ribbon Ad Hoc planning using the Extension of the Admin. It is a huge timesaver. John Goodwin has a pretty good glimpse of it on his blog.

  • Updating of the database of planning

    We have a planning application that is used as follows: the contour is administered through planning, but everything else (like data entry, etc.) takes place using excel. We end up with a lot of fragmentation and I wanted to install a script for fragmenting the Pb from time to time. This is because it is an app planning will a MaxL script running on essbase ('alter database force restructuring") make the case or restructuring must be done with refresh via Planning-> manage-> refresh database databases?

    Thank you.

    If you want to defragment then Yes, you can run a maxl restructuring and she doesn't have to be an update of the planning.

  • updating of the database in a different version

    Oracle 11.2.0.1 and 11.2.0.3.

    Can rman update database 11.2.0.1 to 11.2.0.3?

    In other words, my source database is 11.2.0.1, my target database is 11.2.0.3

    I want to update the target database source database. Is permitted because the version is different?

    Appreciate any help.

    S.

    Hello;

    No, is the short answer. To duplicate or to restore the databases must be the same version.

    There is a method of upgrading, but I doubt you want to do this every time.

    DUPLICATE considers both 32-bit and 64-bit of the same operating system as belonging to the same platform.

    See:

    Note to master for Oracle Recovery Manager (RMAN) [ID 1116484.1]

  • Update of the database of the EM12c plugin

    Hi all

    I am facing the problem depending on when I try to update the plugin database on management of a facility of EM12c agents. I have deployed the updated version (u120704) of the WHO database plugin, but when I try to deploy it to the Agents (who already have the old version of the plugin) I don't see any of these Agents because this shows that workers who do not have any plugin deployed database. The documentation clearly indicates that you need not cancel their deployment plugin in order to to refresh. So what I am doing wrong?

  • SYS, SYSTEM and SYSAUX when full update of the database.

    I took a full export of database using below command
    expdp "'/ as sysdba'" full=Y directory=DPUMP_DIR dumpfile=expdp_11032011.dmp logfile=expdp_11032011.log 
    Now, I need to import this file in a different database.

    When schema refresh usually let us down all the object in this scheme and start to cool, but when you do the back upward, we have to drop all the user?
    what the user sys, system and sysaux?

    In general, you need not do anything with the SYS and SYSTEM schemas. Just let it export and import of run and ignore the schemas SYS or SYSTEM errors during import.

    I've never seen a database where SYS MMR SYSTEM does not use default tablespace: I think it is impossible because it is part of the process of creation of database that you cannot change.
