Migrating from single-node to multi-node (2 Node)

Hi,
We have decided to migrate our existing 11.5.9 application from single-node to 2 Node(multi-node). Please let me know what services should reside on each node (Recommended by Oracle).
Forms, Reports, Apache on one node and CM, Admin, DB on another ?
(or)
DB on one node and all other on another node ?
And please let me know the steps I should follow to achieve the task as well.
Thank & Regards,
Abdullah

Faster way to migrate from Single byte to Multi byte

Hello,
We are in the process of migrating from a 9i Single byte db to a 10g Multi byte db. The size of our DB is roughly 125 GB. We have fixed everything in the source database (9i) in terms of seamlessly migrating from a single byte to a multi byte db. The only issue is the migration window - curently we are doing an export/import since there is a character set migration involved and it's taking about 20+ hrs to do the import in 10g. The management wants to cut this down to less than 10 hours, if that's possible. I know the duration it takes to import depends on many factors like the system/OS configuration, SAN, etc but I wanted to know what , in theory, is considered the fastest method of migrating a database from single byte to multi byte.
Have anybody here gone through this before?
Thanks,
Shaji

If the percentage of user tables containing some convertible data (I am assuming you will not have any truncation or lossy data) is low, you can export only those tables, truncate them, and rescan the database. This should report no convertible data, except some CLOBs in Data Dictionary. Such database can be migrated to AL32UTF8 using csalter.plb. After the migration, you import only the previously exported subset of tables.
Note, for this process to work, no convertible VARCHAR2, nor CHAR, nor LONG data can be present in the Data Dictionary.
The process should be refined by dropping and recreating indexes on the exported tables as recreating an index is faster then updating it during import. You should also disable triggers so that they do not interfere with the migration (for example, they should not update any "last_updated" timestamp columns).
If the number and size of affected tables is low compared to the overall size of the database, the time saved may be significant.
There may also be tables that require even more sophisticated approach. Let's say you have a multi-gigabyte table that stores pictures or documents in a BLOB column. The table also has a single text column that keeps some non-ASCII descriptions of the stored entities. Exporting/truncating/importing such table may be still very expensive. A possible optimization is to offload the description column to an auxiliary table (together with ROWIDs), update the original column to NULL, export the auxiliary table, drop it, rescan the database, migrate with csalter.plb, re-import the auxiliary table, and restore the original column. If pictures alone occupy, for example, 30% of the whole database, such approach should yield significant time saving.

Migrate from single instance to RAC manually

Hi,
I have a 10g database running in single instance.I have installed grid 11.2.0.2 in two nodes including the node where current instance is running,I have installed 10g again in a seperate mount point in both the nodes .It has the same patches as single instance 10g home.Now how to migrate from single instance to RAC manually.
Thanks,
Sekar

-restore this database into 11g ASM if its not already on ASM.
-upgrade this database to 11g from 10g on single instance.
-Now Converting Single Instance on a Cluster to Oracle RAC ,here you have different option to perform this once its 11g database after upgrade.
using rconfig
using dbca or manually.

Migration from Single Node to RAC Node

Hi,
We are planning to migrate the Database from Single-Node to RAC Node. Are there any checklist list to be considered regarding Performance, System and Database ( or any other topic), before migrating to RAC.
Thanks

If it is already the same version, you will need to focus any "single-threadedness" of the application like sequences that are mandatory sequential, "semaphore-style" locking etc...
My experience is that going RAC and in particular to ASM can give a performance boost. If it is the same version (11gR2 for example) then any statistics-related performance issues will still be there.

Migrate from single server to multiserver path?

I'm looking to move from a single Exchange 2013server to multi server for HA, i.e. multiple database servers and client access servers. What the best way to migrate? I would like to keep the existing single server as a client access server. I'll
be using a hardware load balancer for the client access servers. Existing 2013 Exchange server has Windows 2012 Datacenter installed.
Can just make a new database sever and create a DAG then create a new client access server then configure the load balancer?
Thanks for any input on how to migrate from a single server to multiple server for additional HA.

Is there any benefit to using Server 2012 R2 vs Server 2012 R1? The single server is currently Server 2012 R1. Can I do an in place upgrade from 2012 R1 to R2 without messing up Exchange?
Here's my thoughts so far:
1. Make 3 additional 2012 R1 servers
2. On 2 of the servers install additional Exchange servers with mailbox database roles (it appears each new mailbox server comes with a database which I'll delete).
3. On the last new server, install CAS role
4. Create DAG with all 3 servers with database role
5. Add production database copies to DAG
6. Configure load balancer for CAS load balancing
Thoughts? Is the production database on the single server available while a copy is being made to the new mailbox database servers? Also, I thought I read some where to move mailboxes to DAG, but I don't see why if I can just add copies of the existing
database to the DAG group.

Migrating from single processor to dual processor Callmanager

Hi Networkers,
had anyone install a Callmanager 4.1 dual processor version of CM4.1-K9-X345D= before in a single CPU in a dual processor capable server before.
Can it work in the first place?
Had anyone successfully migrate it to a dual-processor later on?

I dont think there is any difference in Callmanager software for a dual processor versus single processor server. For 7845 (dual processor) the hardware detection disks may be different from the one for single processor (7825, 7835)
Migrating from one to another is as easy as taking a BARS backup from one server, build the other server to the same version and restore it. (Make sure server name and ip are the same for both servers)

Domain Migration :from single domain to multiple domain.

Hi ,
We have an urgent requirement for the domain migration
The scenario is currently we are using MS AD as LDAP server to store portal users and thier credentials.
Lets say we have current domain name as : ad.abc.com
we are planning to migrate from this domain to number of domains.our requirement is to move the portal users into thier specific domain in batches.eg out of 5 users 2 has been moved to new domain and other 3 are still in ad.abc.com.
But after domain migration ,all the 5 users <b>should</b> be able to access all the applications and functionality of portals.
What should we do to achieve the same?
How portal applications will be affected by this?Can all the users access all applications without fail?
What exactly the LDAP does in portals?
Any help will be greatly appreciated
Thanks in Advance
Amit

Hi,
Yes, you need to prepare Active Directory and domains.
What's more, you need to upgrade existing Exchange 2007 servers to Exchange 2007 Service Pack 2 at least.
Here is an article for your reference.

Upgrading from single processor to multi processor

I am looking for information on upgrading a 7.3 Oracle from a
single processor to a multi processor. I will be putting in
another processor in my server and would like to know how to get
Oracle to use this second processor. I know that I need to
upgrade Windows NT to multiprocessor first but what do I need to
do after that with Oracle.

I'm not certain why that would be the wrong boards. I guess HP has the wrong boards posted on their product's support site at the link below.

Move hana db from single tenant to multi tenant

Hi experts,
I have read that, for the moment, we cannot do an upgrade of a SAP system + conversion to a multi tenant Hana database in one shot. We have to deploy it on a single tenant and then move it to a multi tenant environment (where we can put a series of systems). Am I right? Right now we have a single tenant environment (A), and a multi tenant environment (B).
How can we move the database from a single tenant to a multi tenant?
- do we need to 'upgrade' the single tenant (A) to a multi tenant and then put it to our other multi tenant (B) environment? Problem here is that we then lose our single tenant environment for deploying new systems. We then need to redeploy everything, no?
- or do we just need to restore the system database to the multi tenant database?
Regards,
Kenny

Hi,
Have you changed the <sid>adm user environment variables?
You can resolve this problem using system copy procedure.
Use installation master,, export database and Instance files ..

MDT from Single Site for Multi Domain OS Deployment

Hi all,
We are looking for a solution which will make it possible to use MDT from a single site to deploy Windows 7 or Windows 8 and join different domains of different customers without trust relationships between domains.
We are a service provider which supports different customers with separate domains. At this moment those different customers have their own WDS server on site and administration is time consuming because a lot of hardware changes occur.
We are now searching for a solution which is easier to manage and one of the solutions we are thinking about is to install a WDS server in our office and use MDT for some custom task sequences but just build one image with all the different driver packs we
have.
Does anyone know how to deal with this from our point of view. All tooling I can find is based on Enterprise clients with one Domain Forest and maybe some different sites but all in one domain, which makes deployment a bit easier then in our situation I guess
as we are looking for a solution that supports Multi-domain deployment.
Hope someone might experienced this before and can help us in the right direction. If someone has experience with additional tooling which might help us I am more then interested to know how the tooling helped in solving this.
Preferrably we had a tool which was Multi-tenant and multiple domains could be managed from a single console, but I think that tool just doesn't exist.
Hope someone is able to help us in the right direction. Please let me know if you have any tips or did experience the same while making a Deployment plan for the service provider you are working for.
Many thanks in advance!

So is the goal is not only to get multiple domains to select from, if so you could use a DomainOUList.xml file .
Also would the clients be imaged at your site or your clients site?

Converting from Single Byte to Multi Byte character set

Hello,
I'm trying to migrate one schema, including data, from a 10g (10.1.0.2.0) DB with IW8ISO8859P8 character set, to a 10g (10.2.0.1.0) DB with AL32UTF8 character set.
The original tables are using VARCHAR2 columns, including some VARCHAR2(1) columns.
I'm trying to use exp and imp for the task, but during import I'm receiving errors like:
IMP-00019: row rejected due to ORACLE error 12899
IMP-00003: ORACLE error 12899 encountered
ORA-12899: value too large for column "SHAMAUT"."TIKIM"."GAR_SET" (actual: 2, maximum: 1)These errors are not limited to the one-character columns only.
Is there a way to export/import the data with AL32UTF8 in mind, so the system will automatically convert the data properly?
Thanks for the help,
Arie.

It's not a true conversion problem that you have but more a space problem. Tables columns are created by default with the init. parameter NLS_LENGTH_SEMANTICS character semantics:
If NLS_LENGTH_SEMANTICS = BYTE
then 1 character = 1 byte whatever the db character set
If NLS_LENGTH_SEMANTICS = CHAR
then 1 character = 1 character size for the db character set.
If this parameter is changed it is only taken into account for newly created tables or columns: existing columns are not changed.
See http://download-uk.oracle.com/docs/cd/B10501_01/server.920/a96529/ch2.htm#104327
The only solution I see is to enlarge your VARCHAR2 columns before running the import...

How does a RAC DB 'spread' from single instance to multiple instances ?

GI/RDBMS Version: 11.2.0.3
OS: Oracle Linux 6.3
Filesystem : ASM
When a RAC database is created using dbca , Manually , or RMAN restore, the DB is created in the Node1 first with cluster_Database=FALSE .
Then you run the following commands (for 3-node RAC) from Node1
srvctl add database -d lmnprod -o $ORACLE_HOME -p +LMNPROD_DATA01/lmnprod/spfilelmnprod.ora
srvctl add instance -d lmnprod -i lmnprod1 -n hwcarser290
srvctl add instance -d lmnprod -i lmnprod2 -n hwcarser291
srvctl add instance -d lmnprod -i lmnprod3 -n hwcarser292
Once the DB is created,mounted and opened in Node1 and the above commands are executed , you set cluster_Database=TRUE and startup the Instance2 and Instance 3 in Node2 and Node3.
I just want to know how does Node2 and Node3 becomes aware of the DB and joins the DB cluster ? What happens internally ?

Generally speaking, registering in OCR is not required for database to be a cluster database.
Migration from single-instance database to cluster consists of creating redo logs and undo tablespace for new instance and enabling this instance (thread). If database is policy-managed, this is done automatically for new node.

We have installed oracle Linux cluster.
Please help me which way I can go with RAC.

Migrating to a single instance will be the simplest. The migration itself will not be much different between the two because you're migrating from one platform to another. The options you have available are, the traditional IMP/EXP, datapump, and RMAN to migrate to either a standalone or RAC environment. The difficulty will be in creating a RAC environment and a little a few extra steps in the RMAN restore. Working with RAC will make things harder, but the actual migration is similar. The steps to IMP/EXP, whether it's traditional or Datapump will be no different. However, standing up a RAC database will be.
