Prerequsites before Repository Migration

Dears,
We need to perform repository migration from Dev environment to Production environment. Can anyone please confirm me what are prerequisites need to be taken before performing?
Please correct me if I am wrong & let me know If I miss anything. I think we need to:-
1.) Take backup of Production repository (i.e. by exporting the Prod repository)
2.) Need to take the backup of the production server installed folder (i.e. sba81 folder (installed folder))
Please let me know anything more need to be taken as backup. Your help is highly appreciated.
Regards,
Abi

I think there are two different things in your questions.
Your primary question is what you have to do for a DEV2PROD.
One of the sub questions is, if you should make a backup of the current repository in PROD.
You can import a repository (with a different name), but it won't be active.
Or you can stop the server, rename the current repository and import the new repository with the name "Siebel Repository".
Once that is done, you can do the DDLSYNC, to make the new columns/tables active.
Workflows are migrated with the new repository, but still need to be activated.
The application will need the new SRF, as most of the functionality is run from the SRF and not from the repository.
To answer your sub question about exporting the PROD repository, you have to find out if release files are stored somewhere.
If they keep older copies of the previous releases, there is no need to export the PROD repository.
So in the case that earlier release files are not kept (or this is your first release), you can export the repository from PROD.

OBIEE 10g incremental repository migration

Could someone direct me to an Oracle document or previous post that clarifies if incremental OBIEE repository migration utilizing copy/paste between two offline repositories is supported, and if doing so viloates any Oracle warranty? We're on version 10.1.3.2. Thanks.

thanks bifacts. i have reviewed this article before and conducting our migrations the way it describes, but have recently been told that this approach is no longer supported by Oracle (i.e., incremental copy/paste). can you confirm if it's supported? or, to ask another way, are there any Oracle support risks associated to heading down this path?

Need details about the BI repository migration

I have a requirement coming my way, although I am not working in Technology related to BI , my client insists me to do some BI repository migration.
His requirement was that he has already done the cloning part of the DB, now all he wants is , the BI repository needs to be reproduced from the current server to another server.
Kindly let me know any pointers for this BI repository migration.
Thanks in advance.

OBIEE Repository migration

Hello Guys,
I ran into a strange problem today. I am using repository migration to migrate my objects from one repository to the other. There are some dummy presentation table that i created to nest some of the presentation tables under it.
After the repository migration strangely all my dummy folders are gone from the presentation layer. It will only display the presentation tables that have columns under it.
I end up manually creating those dummy presentation tables again after the migration.
Is this a known behaviour or am i missing some thing here? Please advice
Thanks
Prasanth Gurram

Its a known bug. What oracle says about it is, A presentation table should have at least one column, Then only it considers for migration.
In your case what you have to do is create a dummy column and remove read access for every one. So that we will overcome the problem in the rpd mgiration.

= Help PLEASE ! (Designer repository migration 6i)

Hi everybody,
(Oracle Designer 2000 repository migration from 6 to 6i)
I'd like to know where can I find the script 'migrate_repos_privs.sql'. The propose of this script is to migrato users from the old repository version to 6i.
I start with repository version 6 and I try to execute this script. The source of this script try to call 'jr_sys_privs.ins' package internally but it doesn't exist in old repository. The result obviously is an error 'pl/sql called not found'.
This is the fouth step (4/5) in the tutorial instructions. Next I'm going to push the 'migrate repository' button in the tool to complete the migrate process.
Thanks. (Please, send me copy of your answers to: [email protected] )
Best regards:
Richard.

Hi,
The MIGRATE_REPOS_USERS.SQL script is generated when you run the the CKGENUSR.SQL script (step 12.1 of the insallation guide). In the box at the beginning of '12:Migration of subordinate users'it describes how when you run CKGENUSR.SQL it generates the MIGRATE_REPOS_USERS.SQL to your working directory.
check your working directory after running CKGENUSR.SQL you should find the script there.

Bulk notification before mailbox migration

Hello,
I will start mailbox migration from Exchange 2010 to 2013 per databases. Can you please let me know how I can send out a bulk email notifications to the users in the mailbox database before the migration?
Thanks

$Boxes = Get-Mailbox -Database DB01
Foreach ($Box in $Boxes){Send-MailMessage -Subject "Migration" -Body "your being moved tonight"
-From "[email protected]" -To $Box.PrimarySmtpAddress -SmtpServer "smtp.domain.com"}
That should do it.

Replication before the migration

Hi Guys
my Domain controllers are the next
DC1 192.168.2.2 (2003)
DC2 192.168.2.3 (2003)
New domain
DC01 192.168.2.4 (2008)
DC02 192.168.2.5 (2008)
DC1 and DC2 are replicating over Failover ( DHCP, DNS..)
i want to know before i migrate the FSMO roles over to the New DC01, do i need to disable the replication before the migration or not ?
thank you

On the new DC can you post the output of:
dnscmd /enumdirectorypartitions
this is the output:

Export data from database table before database migration

Hello,
We are planning to migrate our SAP ERP 6 Ehp4/NW7.01 from Oracle 11.2 to IBM DB2 v. 9.7 database. During test migrations I have established that we spend a lot of time for one particular table (COEP). Because we donu2019t have possibility to archive this table before migration I have an idea to export data from previous years from this table to the file system (using an ABAP report), delete those data from table before migration and then after migration, import back to the database from the file system.
Does anybody have any concerns or suggestions about this idea?
Thank you for your answers
Andrej

Hello Andrej,
I strongly do not recommend to do so.
I am not sure whether technically this could work at all..
Even it if would work .. In order to really save time, the export and the import would have to be a dirty one (meaning the system is operational and in production). With this there is a high risk to produce inconsistencies on this table. And you most likely will receive no support if something unforeseen happens and you end with problems.
Also your approach (if it should work at all) , would have to be tested thoroughly by you , also protecting the table from any changes.
I do not believe that this can save any effort compared to implementing advanced migration techniques like table splitting.
On top, you would go high risk to end with an unsupported system, with not using official migration procedures

Data Miner Extension in SQL Developer 4.0 EA3 Release: EA3 Repository Migration Failure

The Data Miner extension in the SQL Developer 4.0 EA3 release fails when attempting to migrate the repository to EA3. This posting contains instructions on how to recover from this failure as well as to successful migrate the repository from EA2 to EA3. There are no problems when just installing a fresh Data Miner repository.
Sorry about the difficulty if this has caused you any problems.
Mark
Failure message displayed in log when migrating to EA3:
Error report -
ORA-06550: line 96, column 40:
PLS-00382: expression is of wrong type
ORA-06550: line 96, column 7:
PL/SQL: Statement ignored
06550. 00000 - "line %s, column %s:\n%s"
*Cause: Usually a PL/SQL compilation error.
*Action:
Instructions on how to recover from failure and continue using original version of SQL Developer:
1) Execute the following sql as SYS in order to allow the Data Miner repository to be open for use again:
UPDATE ODMRSYS.ODMR$REPOSITORY_PROPERTIES
SET PROPERTY_STR_VALUE = 'LOADED'
WHERE PROPERTY_NAME = 'REPOSITORY_STATUS';
COMMIT;
2) During attempted migrationto EA3 failed, access priviliges to the Data Miner repository are revoked from users. In order to use Data Miner again, these grants must be reapplied. You can either use the UI guided process to accomplish this, which requires the SYS password, or you can run the usergrants.sql script, again as the SYS user. For instructions on how to run the usergrants.sql script, or any adminstrative script, review the instructions contained in the install_scripts_readme.html file. You can find this file in the SQL Developer directories created when you unzipped SQL Developer. It is located in the following relative directory: \<SQL Developer Install Directory>\sqldeveloper\dataminer\scripts.
Instructions on how to successfully migrate to EA3.
If you have already attempted to migrate to EA3 and failed, then you need to perform the recovery instructions noted above, after which you can continue with the instructions below.
If you have not yet attempted to migrate to EA3, then just following the instructions below.
1) Replace all contents the script file createxmlworkflowsbackup.sql with specification contained at the end of this posting. The file to edit can be found in the \<SQL Developer Install Directory>\sqldeveloper\dataminer\scripts directory.
2) After completing the edit to createxmlworkflowsbackup.sql, you can proceed with the UI guided migration or perform the migration using the appropriate migration script. Review the install_scripts_readme.html file in the /dataminer/scripts directory for instructions on how to perform the migration using the script. For the UI migration, simply open any user connection in your Data Miner navigator, and you will be prompted to perform the migration.

Deauthorize iTunes before starting migration to new Mac

I bought a new iMac and will soon be migrating the files from my old iMac to the new one. Will I have any problems if I deauthorize iTunes on my old Mac before I start the migration? I already have 5 devices authorized and new Mac will be 6.
Thanks,

Should I uninstall Creative Cloud and CC apps before using migration assistant to my new imac?

I have heard that Creative Cloud and CC apps dont transfer well with the Migration Assistant from Apple.
I have a new iMac with Yosemite. Should I uninstall everything before using the Migration Assistant and then re-install Creative Cloud and apps afterward by downloading from the Adobe site again on the new iMac?
Is there a link to full instructions how to completely uninstall CC and the apps and clean up?

Hi There,
Kindly follow the below mentioned steps.
Try to Sign out, Sign in | Creative Cloud Desktop app
Sign in, activation, or connection errors | CS5.5 and later
If that doesn't help.
Try to uninstall the product and run the Adobe CC cleaner tool to be on a safer side.
Install Creative Cloud app, Install the product again.
Kindly revert if the problem still persists.
Thanks,
Atul Saini
