Migrating System Center Databases from cluster to Standalone

Hi
We have been advised to migrate all our System Center SQL DB's (mainly ConfigMgr, OpsMgr, ServiceMgr and Scorch) which are currently running on mostly 4 nodes SQL clusters (with different other business services and impacting the System Center Performance
as Memory and CPU constantly hitting above 90%) to standalone SQL environment.
OS - Windows Server 2008 R2 / Windows Server 2012
SQL - SQL Server 2008 R2 / SQL Server 2012
Can someone advice steps or strategy to execute this?

Is this the right SQL architecture for System Center?
How do you optimize this? I ran both queries and it returned zero values.
The DR plan is to implement back up strategy with SCDPM and keep backup copies on Azure Cloud. Plus, we will follow the DR plans for each System Center Product.

Migration of Content Databases from SP 2010 "Domain A" to SP 2013 "Domain B"

Hi there,
I am in the process of planning the migration of my SP Foundation 2010 farm to SP Server 2013. I have tested this previously with the following steps and was successful:-
Backup DB on SP2010 SQL
Restore DB on SP 2013 SQL
Run Test-SPContentDatabase –Name WSS_Content_*** –WebApplication
https://intranet.***.com.au
Mount the DB - Mount-SPContentDatabase –Name WSS_Content_*** –DatabaseServer DomainA\SHAREPOINT –WebApplication
https://intranet.***.com.au
Convert Web App - Convert-SPWebApplication -Identity
https://intranet.***.com.au -To Claims -RetainPermissions –Force
Now, the goal posts have changed and we may be moving to another domain. Now, when I run
Test-SPContentDatabase command in Step 3 above on Domain B, I get the error Login Failed for 'DomainA\SP_admin'
- which makes sense.
What would be the best way to restore a DB to a new domain?

you have to perform the same steps....you need new account on the new Domain. then you have to run the migrate user command.

Migration of the database from Microsoft SQL 2014 Express to Microsoft SQL 2012 Server

I posted a similar thread yesterday, and I realized that there was a serious typo.
Link: https://social.msdn.microsoft.com/Forums/sqlserver/en-US/b3e201ea-6c7c-43a4-8908-842b714ea451/migration-of-the-database-from-microsoft-sql-2014-express-to-microsoft-sql-2012-server?forum=sqlservermigration
Therefore, I made a decision to post another thread right now.
I am
writing to ask if there are any known issues when migration from MS SQL 2014 Express to MS SQL 2012 Server version. Are there any step-by-step instruction on how I can go about doing this?
Looking forward to your response. Thank you for your time.

Jeff Yoo

Hello,
SQL Server 2012 setup program won’t allow you to perform a downgrade from SQL Server 2014 Express Edition. Backup/Restore
and Detach/Attach won’t help you either.
One option you have left is using SQL Server Import/Export Wizard as explained on the following article.

Hope this helps.

Re: migrate our ERP database from Solaris Sparc 64 to Linux x86_

hi ,
We want to migrate our ERP database from Solaris Sparc 64 to Linux x86_64 .
Please suggest some docs .

Migrate Oracle 11g database from Windows To Linux using RMAN hot / cold backup ?

Hi Friends,
Is it possible to Migrate Oracle 11g database from Windows To Linux using RMAN hot / cold backup ? ( as i would like to perform Point In Time recovery)
(or) The only way is to use RMAN convert as mentioned here - Transporting Data Across Platforms
(or) Is there any other method (except exp/imp and data pump)
Regards,
DB

HI
his post describes the procedure required to migrate a database from Windows to Linux using the RMAN Convert Database command.
Both Windows and Linux platforms have the same endian format, which makes possible to transfer the whole database, making the migration process very straightforward and simple.
To migrate between platforms that have a different endian format, Cross Platform Transportable Tablespaces (XTTS) needs to be used instead.
List of Steps Needed to Complete the Migration
The migration process is simple, but as it has several steps it is convenient to be familiar with them before running it.
1. Check platform compatibility between source and target OS
2. Start the database in read only mode
3. Check database readiness for transport from Windows to Linux using DBMS_TDB.CHECK_DB
4. Check if there are any external objects
5. Execute the Rman Convert database command
6. Copy converted datafiles, generated Transport Script and Parameter File to Linux
7. Edit the init.ora for the new database
8. Edit the Transport Script and Parameter File changing the windows paths to Linux Paths
9. Execute the Transport Script
10.Change the Database ID
11.Check database integrity
Thank you

To move/migrate the 11i Apps Database alone means you need to follow the export/import method.
Please refer the note: 362205.1 "10g Release 2 Export/Import Process for Oracle Applications Release 11i"
In general steps to follow the DB migration is :
1. create the complete export file in source database
2.create a new DB in the target instance
3.perform the import
4.create the new auto-config and sync with apps tier

Trying to migrate Ultiboard user database from Ver 11 to 12

I updated my software to Ver 12, and noticed that my user database did not migrate. I then copied my ver 11 user db to the Ver 12 location and restarted Ultiboard. Upon invoking Ultiboard, I received a diagnostic stating that my user database was the wrong version and would not be useable. So how do I migrate my user database, and why wasn't this part of the update procedure in the first place?
Solved!
Go to Solution.

Thank you for your quick reply,
Here are 3 screenshots containing the Version (which is education), path and the error message.
Please let me know if you need more information.

Migrate oracle 9iR2 database from Suse to Red Hat???

Hi Everyone,
We're going to move an oracle 9iR2 database from Suse to Red Hat. At this moment I don't know the detail about the platforms yet. I still like to ask a question if DB backup on Suse is compatible on RedHat? Physical restoring may be our prefer instead of exp/imp.
Any advices?
Thanks,
Eric

I'm pretty sure (never did it myself) that there will be not problem when moving the database. The Oracle software is the same (at least when you use the x86 version) so
the format of the datafiles and controlfiles should be identical.
However some configuration files (network settings) might differ so try before you die :-)

How to migrate 11gr2 standby database from file system to ASM

Hi,
I have 11gR2 data guard setup of 2 node RAC primary and stand alone standby database.
Primary RAC uses ASM, and stand alone standby DB uses normal file system for data files and archive logs. I want to migrate the stand alone standby DB from file system to ASM.
If you have any ideas or documents on it, kindly please share with me.
Thanks in advance,
Mahipal

Hi Fran,
Thanks a lot for the quick reply. I have another question, I want to have standby in ASM; but ASM home is grid home(CRS+ASM) in 11gr2.
I don't want to configure CRS now for standby, only want to have ASM storage. s it possible to install the grid home only for ASM and not for CRS?
On a stand-alone system, there are still CRS/Grid components that are a part of the ASM install. You cannot NOT install it.

Convert from Cluster to Standalone

Hello.
I'm seeking some advice on an issue I need to overcome.
I have a SQL2012 Cluster running on Windows Server 2012 on XenServer. All cluster related storage is provided via iSCSI. The device that is providing the storage is failing and I need migrate the data off of that device with as little downtime as possible.
I also would like to avoid having to install a non-clustered instance of SQL Server..
Based on my research, it seems like what I'm trying to achieve is not impossible
This thread here: http://www.mssqltips.com/sqlservertip/2355/dismantling-a-sql-server-cluster-after-a-p2v-physical-to-virtual-migration/
Seems to be my best way forward given the fact that I want to resuse the existing installation and data. My plan is to snapshot my AD servers and SQL servers then with SQL and Clustering shutdown. After that, here is what I've come up with:
1. Remove Failover Clustering
2. Ensure iSCSI disk for SQL Data is mounted
3. Remove the Cluster key from the registry under HKLM\Software\Microsoft\Microsoft SQL Server\...
4. Add the Cluster IP to the host vNIC
5. Restart SQL Server and validate it "works"
6. Stop SQL Server and move data files and etc to new destination
7. Disconnect iSCSI disk
8. Change drive letter of new data disk
9. Restart SQL Server
Anyone mind sanity checking my logic here? When I remove the cluster service and resources, will that also remove SQL Server Instance/Service?
TIA,
Errol Neal

Have you considered storage replication as a solution? You introduce a 3rd node in your SQL Server failover clustered instance but using a disk that is an exact replica of your existing one. This is typically done for a geographically dispersed clusters.
The storage subsystem for the nodes are not shared so you can have different ones per node so long as the storage is replicated on a block-level.
Also, you can introduce another shared storage in your WSFC, shutdown SQL Server and copy all of the database files on the new storage via ROBOCOPY. Once done, you can swap the drive letters of the disks to make SQL Server think like nothing has changed.
So long as the drive letters of the new clustered disks are the same as the old one, everything will work fine.
Another option is configuring an Availability Group as a temporary solution while you fix the storage on your cluster. Add another node on your existing WSFC and install a standalone SQL Server 2012 instance on it. Configure an Availability Group between
the two and failover the databases to this instance while you fix the storage on your SQL Server failover clustered instance.
I don't recommend taking a snapshot of AD. Keep in mind that you have other objects in AD that may be affected when you take a snapshot. You may end up introducing issues in your environment.

Migration of AlwaysON database from WSFC 2008 + SQL2012 to WSFC 2012 + SQL2014

Hello All,
I have a 6 node GEO cluster, 4 nodes in primary site + 2 nodes in secondary site. In the primary node 03 and 04 has 2 pair of SQL instances default + named.
I am planning to move the named SQL pair from WSFC 2008 + SQL2012 TO WSFC 2012 + SQL2014. It has only one AG group with 4 TB of DBs.
Do you guys have any experience and options for this migration. I am planning to go with backup/restore. Let me share yours inputs.
1. Backup/restore 2. cross cluster migration 3.Detach/attach 4. SAN migration
Thanks!
Muthukkumaran Kaliyamoorthy
Helping SQL DBAs and Developers >>> SqlserverBlogForum

Since WSFC does not support rolling upgrades, you will need to have another WSFC running Windows Server 2012/R2 (R2 is highly recommended due to the features available for maintaining high availability) and do a cross-cluster migration. Refer to this documentation
for more details.
https://msdn.microsoft.com/en-us/library/jj873730.aspx
This requires that you're fairly comfortable with PowerShell.
The main challenge here is dealing with hardware resources since you will need additional servers when moving into the new WSFC. You would have to run multiple instances on the same cluster node while you remove a node and repurpose it for WSFC 2012/R2.
This is where proper planning is very important to make sure you are maximizing your resources while minimizing downtime. I cannot speak about the capabilities of your SAN as each vendor will have different features but my approach has always been dependent
on SLAs and recovery objectives. Backup/restore will still be needed to synchronize your data from the old WSFC to the target WSFC.

Migrating GNU dbm databases from SPARC to x86

We're retiring a few of our older SPARC workhorses and moving the processes to x86 VirtualBox OpenSolaris guests. Unfortunately, the primary platform engine uses GNU dbm database files which are big endian on the SPARC. Since these files are heavily loaded and would be tough to restart from scratch, I'm looking for a way to convert the big endian, multi-gigabyte files to little endian so we can simply move then to the x86 platform.
Anyone have a trick up their sleeve?
Thanks
Tim

Thanks - it turns out that one of our Python gurus came up with this same scenario. We dump the tables to text, write them to LTO-3 tape with BRU, restore them onto the x86 system and then re-import them.
Not as clean as I'd hoped, but definitely successful. He'd moved things over by the time we got in this morning (for him, this was an "oh yeah? Well watch this" moment, so he stuck with it til after 2am this morning :-) ).
Thanks.

Restore a database from RAC to standalone oracle server

Hi,
I wanted to know whether we can restore a RAC database to a standalone machine. Steps which i am planning to do
1) Create a stand alone server
2) Install oracle in the same path as that in RAC
3) Create a database of the same name
4) Re direct Restore to this location from RAC database
The database is non asm. Can any one let me know whether RAC database support redirect restore.
Amith

This is possible.You won't have to create the new database though. Rman will do this for you (after all, you restore/recover a full database). It is much easier when you also use ASM on the destination but is you do not want to use asm, you can still use rman to rename/relocate all datafiles to a non-asm location.

This opens the Database Migration dialog box, which indicates the capture process starts normally. we get the following error:
ora :01440 : can not insert null into migrlog (id column) ,
\and then after some time , i get an error that migration failed
I know , that we vcan nt insert null into migrlog table , then pls tell me how can i resolve fro this problem . is there any way to solve it,
i am not getting the reason,I thing it may be due to reason that , I have table's column in my source db with more than 30 character.
If i am migrating one by one table . then it is not giving any error, and identifier name is getting shrink in 30 character. but i am not getting the view , stored procedure , indexes , and others
then what is the solution for that, somebody pls suggest any help?????????????
