DB migration from non cluster to cluster

Hi,
Currently we are installating production on non cluster environment on windows.In future we have to convert this environment as cluster(MSCS).Is there an issues to migrate non cluster to cluster on windows 2003 ,SQL2005 MSCS cluster.
What are the challenges we have to face.
Thanks

i just had raw disk allocated in my windows but asmtoolg could not find the disk while configuring ?

had better post your question in ASM forum, you will get better guidance/reply there.

System refresh from non-cluster to a MSCS cluster system

I have a system (call GTA) running NW 7.0 SR2 with both ABAP and Java instance. It runs on WIndows 2003 64-bit and SQL Server 2005. Now we want to migrate to a new set of hardware with Microsoft cluster (MSCS). I have installed this new system (Call GTB), MSCS clustered with both ABAP and Java instance and running no problem.
Now I am at the last point of the migration -- which I need refresh database GTB from GTA to capture live data. In WAS 6.40 ABAP, I just need perform a database backup/restore and execute SAPINST tool and everything works. Now based on SAP's "System Copy Guide", I need run export on source system and then run import on target system. In source system, it seems straight to export since it's central system (ABAP+ Java). However, when I get to target system, and when I choose cluster, it listed all items I have to choose (ABAP, SCS, 1st node, 2nd node, DB, enqueue, etc). They are exactly the same as a new installation. My questions are:
1. Do I have to go through all these steps for just refresh a database? If I go through these installation, am I overwrite something in my GTQ from GTA unnecessnaryly?
2. Can I just perform a database backup/restore? But what kind steps I need do to make cluster work after database refresh since original databse (GTA) is not a cluster system?
I appreciate you can provide some advise and share some experiences.
Thanks,
Yujun Ran

Hi
I have used the FROMUSER and TOUSER option of the IMPORT cmd to perform a system copy like you have described.
Steps:
1) Export BW4 (EXPORT USER=SAPBW4 ... )
2) In MCOD database, delete/drop all objects belonging to SAPBW1. From memory, I think I found it easier to DROP USER SAPBW1 CASCADE and the recreate the SAPBW1 user.
3) Import BW4 export (IMPORT FROMUSER=SAPBW4 TOUSER=SAPBW1 ..)
I don't use MCOD anymore because it is such a pain to refresh the systems.

Migrating from non-loggin Informix to Oracle (use of transactions)

I wonder what happens when I migrate an Informix non-logging database to Oracle. Since my database doesn't use transaction (that's to say: a single DML sentence define a transaction and ttransactions using begin/commit/rolback trans are not used), applications are written with no transaction philosophy. But Oracle is ANSI-compliant and then when I execute a DML sentence, a transaction begin and it'll finish until I send commit or logout. Then, even when migration is ok, my applications will create very large transactions.

Hi Oscar,
Without actually viewing the Client application code, I can only make general assumptions..
You will have to change the client code anyway in order for it to work with Oracle e.g. Informix E/SQL -> Oracle Pro*C. The E/SQL Client code will have to be updated to reflect various changes in the DB environment; for example:
1. The use of REF CURSORS (passing them back to the client code)
2. Changes to the hardcoded Informix SQL statements to make them Oracle friendly (especially OUTER joins if you migrating to Oracle 8i)
3. Altering any E/SQL code that dynamically builds SQL statements (to make sure these SQL statements are syntactically correct in the Oracle model).
4. DB Connection methodologies.
5. Changing Informix #include files to reference equivalent Oracle #includes
6. Differences in date structs and how E/SQL and Pro*C handle dates (Oracle did not support milliseconds until 9i)
7. Exception handling.
8. Datatype changes between Informix and Oracle.
Again, there is no simple solution. A migration project that migrated the DB and Applications 'in tandem' would make it easier to remove logic from the client code and place it in the server (always a good thing) but this may not be feasable in your case.

What should I do? Is there some parameter to configure Oracle in such way it create single-DML transaction (I heard there's something like that in SQL*Plus, but I'm not sure)? Or should I rewrite applications sending commits after every sentence (The worst case, I think)?
Thanks in advance

Migration from non-Firewire MacBook to new Retina MacBook

I have just purchased a new Retina MacBook. My current MacBook is the 2008 model without a Firewire port. Since the old MacBook does not have Firewire or Thunderbolt, and the new MacBook does not have Ethernet, I am left with Wi-Fi as the migration alternative. I suspect that this will be a VERY slow procedure.
I do have an external USB 2 hard drive with a full bootable backup. My question is: Can I connect this hard drive via USB to the new MacBook and migrate the files? If so, would this be faster than using Wi-Fi?
Thanks for any advice.

Just to add a bit about my experiences with the transfer. It did finally work, but it wasn't easy!
When I finally got the cable (after Fedex lost it for 3 days), the instructions on the Apple site were totally inadequate. They didn't explain that you should turn off wi-fi on the computers, or how to set them up for Ethernet transfer on the Network screen, then get them back on wi-fi when you were done. This was not as easy as it should have been -- or at least not for me!
I finally got the two connected properly and then realized (this was admittedly my fault) that I had not upgraded the Migration Assistant on the old computer. So I had to go back and start from zero again.
I also could not get the window to open to give me a choice of which sub-folders to transfer. So I ended up transferring everything. Not a major issue, but just more time consuming.
However, once finished, everything was pretty much where it belonged, and all my apps were fine. The only one that gave me any problem was Dreamweaver. The transfer did not move DWs configuration files, but I was able to fix that by copying that Configuration folder over to the new computer via wi-fi.
By the way, those instructions that Ogelthorpe linked to, even though they say they are for 10.6, are more complete and explicit than the ones on the Apple site specifically for Mavericks. So thanks very much for the help!

Migrating from Non-XA driver type to XA Driver in Weblogic 11g

I have two data sources created in weblogic 11g which were configured in following manner and we are using this configuration since our application started supporting weblogic as application server that's Weblogic 9i.
Database A: Participates in Global Transaction
Driver Type: Oracle Thin Driver non-XA
Support Global Transaction option is disabled for this data source.
Database B: Participates in Global Transaction
Driver Type: Oracle Thin Driver non-XA
Support Global Transaction option is enabled for this data source with One Phase Commit enabled.
If we use this configuration our application run just fine without any issues.
Now we have a requirement of adding another data source which participates in global transactions.When I create this data source with following settings,
Driver Type: Oracle Thin Driver non-XA
Support Global Transaction option is enabled for this data source with One Phase Commit enabled.
This results in error (which was expected) "
"*SQL ERROR: Connection has already been created in this tx context for pool named CMDEMO. Illegal attempt to create connection from another pool: EXPDB*"
and even when I enable "Support Global Transaction" option with LLR or Emulate Two phase Commit option this results is error,
"*Database Error: Unexpected exception in Non XA Resource enlistment. Resource=JDBC LLR, pool=EXPDB, table=WL_LLR_ADMINSERVER Cannot enlist more*
than one Non XA Resource. Attempt to enlist 'WL_JDBC_LLR_POOL.EXPDB' when 'WL_JDBC_LLR_POOL.CMDEMO' is already enlisted."
Now we are planning to move to "Oracle Thin Driver XA" driver type for all the three data sources.I tested this config. and all global transaction are getting executed perfectly.
But before we adopt this change,I just wanted to check what all are the limitations of using XA driver or any potential issues that needs to be tested. I explored about this and came to know that XA comes with performance overhead ,frequent database locking with SQL Server driver, and some conflicts with multibyte character sets etc.
Can someone please provide some input on how to tread ahead and what all things needs to tested.

How are you using these connection pools in your application?
Do you have different EJB's, which have the default transaction attribute configured (@TransactionAttribute(TransactionAttributeType.REQUIRED)),
and are calling each other?
If one EJB is using connection pool A and the other is using connection pool B, you get in trouble because the transaction is already
started by EJBone and is propagated to EJBother. In this case you can use @TransactionAttribute(TransactionAttributeType.REQUIRES_NEW).
Now a new transaction is started for EJBother.
Some information about XA
The primary difference is that data sources that support global transactions are JTA transaction-aware.
Realize that JTA transactions do not necessarily mean XA transactions and two-phase commits (2PC). JTA
transactions also allow two independently written components that modify the same database to participate
in a transaction without having to know about each other. Non-XA database transactions require the
use of a single database connection to provide the proper transactional semantics. If you choose not to
use the Supports Global Transactions option, you need to write your application components in such
a way that they get a database connection from the pool at the start of every transaction and pass that
connection around to every component that participates in the transaction. This is clearly not desirable
and not even possible with certain types of components (for example, JPA managed entities).
A data source that supports global transactions will make sure that your components participating in a
JTA transaction get the proper transactional semantics whether or not they are using XA transactions.
When not using XA transactions, the data source accomplishes this by associating a database connection
with a JTA transaction context. Every time a component asks for a database connection using the data
source that supports global transactions, WebLogic Server will check to see if the current transaction
already has a database connection, and if so, it will always hand back the same underlying database connection.
This allows non-XA transactions to maintain the proper database semantic guarantees without
having to worry about what database connection to use and what the transactional boundaries are for
the application.

Database migration from non rac and non asm to RAC database with ASM

HI,
i have requirement to import one database ( db1) which running one node with out ASM and with out RAC , now i want to import that database with rman backup to another database ( db2) which running on different server with 3 node RAC and ASM ( disk group +DATA ) , can you please provide me the steps how i can migrate.? ( i have created db2 with dbca with RAC).
regards,
sri

Sri,
This could be done multiple ways. Simplest for you is to use DBCA:

Cluster - Non-cluster aware application

Hi everyone,
I need to migrate some non-cluster aware application from windows server 2003 to windows server 2008 R2 or windows server 2012.
On windows server 2003, the cluster service start with a specific domain user to let some access.
I have seen some solutions like "RUNAS" in cmd or a powershell script or VBS.
But my problem is:
How can i start or create non-cluster aware application with user domain access and with "clean work" ?
Thanks

Windows services are installed with an associated account. You can define that to be whatever you want, either a local machine account, local system account, or a domain account.
To make it much, much easier than was possible with clustering in 2003, Windows Server 2012 (suggest using R2) comes with a cluster role of Generic Service.

Migrating from Oracle8.0.x to Oracle10g on OpenVMS

Hello,
We have the Oracle 8.0.5, which runs on the OpenVMS Version 7.2. The Hp documents show that we must upgrade the OpenVMS to 8.2. However, before upgrading the OpenVMS system and migrating Oracle, we really want to know what steps we need to perform before the migration and a procedure to migrate Oracle8 to the latest Oracle version. We appreciate for any advice.
Thank you,
Kelli

Migration from Developer 4.5 to Developer 6i

Hello,
I want to migrate a Oracle forms 4.5 application to developer 6i.
The Forms 4.5 application has been built by using headstart 3.4.2. The application runs on a client-server architecture
Is it possible to migrate to developer 6i without changing the used headstart version and the architecture.
I already heard that we might be some problems with visual attributes in client-server environment ?
who can give me some more information about this combination of architecture and used software and tools ?

Hi,
I would contact Oracle Developer support.

Migration from EP 5.0 to EP 7.0

Hello,
Experts, I have to migrate from EP5 to EP7......below is what I believe....kindly comment
For migrating from EP 5.0 to EP 7.0 you are actually migrating from Non-Netweaver environment to a Netweaver environment.
And you need to first migrate from EP 5 to EP 6...i.e. from Non netweaver to netweaver....
and then only you can migrate from EP 6 to EP7....
Please correct me if I am wrong.

Hello Experts,
Please comment.
