RAC OS plaftform migration

Hi All,
We're planning to migrate Oracle RAC from IBM/AIX to Linux platform. On the RAC/AIX, we have 2 nodes..each node has 2CPUs, 8GB of RAM.
How can we covert 2 cpu 8GB on AIX to be equivalent to number of CPUs and memory on LINUX?
Any advises are greatly appreciated.
Thank you!

You need to look at something like the Matrix of CTP (Composite Theoretical Performance) and MTOPS (Millions of Theoretical Operations Per Second) of the processor and platform to make a call on what the "+equivalence+" is.
You can find this matrix for the AMD processor range at:
http://www.amd.com/us-en/Processors/ProductInformation/0,,30_118_8796_8800~124990,00.html
The CPU technology is used in blade servers (relatively inexpensive) from manufacturers like Sun, HP and others. The Sunfire range of AMD servers is what we typically use ourselves for some years now. Added benefit is that this sold by "+Oracle/Sun+" which means that both your RAC s/w and h/w stacks have the same owner. Good for support and maintenance, and potential leverage when it comes to dealing with discounts. ;-)

Single node file system to 3 node rac and asm migration

hi,
we have several utl_file and external table applications running on 10.2 single node veritas file system. and we want to migrate to 3 node RAC ASM environment. what is the best practices in order to succeed this migration during this migration. thanks.

1. Patch to 10.2.0.3 or 10.2.0.4 if not already there.
2. Dump Veritas from any future consideration.
3. Build and validate the new RAC environment and then plug in your data using transportable tablespaces.
Do not expect the first part of step 3 to work perfectly the first time if you do not have experience building RAC clusters.
This means have appropriate hardware in place for perfecting your skills.
Be sure, too, that you are not trying to do this with blade or 1U servers. You need a minimum of 2U servers to be able
to plug in sufficient hardware to have redundant paths to storage and for cache fusion and public access (a minimum of 6 ports).
And don't let any network admin try to convince you that they can virtualize the network paths: They can not do so successfully
for RAC.

11gR2 RAC stability and migration path

We are preparing to go from a 10g Data Guard environment (1 primary and 1 physical standby) to an 11g RAC cluster on Sun M5000s (Data Guard will not be part of the final configuration). We have heard that 11gR2 RAC is not yet mature enough so we are considering going to 11gR1. I'm curious what the general consensus is regarding the stability of 11gR2 RAC.
Also wondering what the best migration path would be. We are considering upgrading the 10g Data Guard databases to 11g and then creating a RAC physical standby database on the 11g cluster for the primary database on the old server. The migration to the new RAC cluster will consist of a failover to the new 11g RAC database and will involve minimal downtime. The 10g Data Guard databases and servers will then be decommissioned.
Thoughts?

You will be surprised if I said Oracle RAC11gR2 seems to be a new version NOT a new realease of Oracle RAC11gR1.
Many new features, surprises, bugs, yes bugs....
I suggest to directly address to Oracle itself , to your support at Oracle , as it seems to be a production DB. DOnt take the risk to decide from this forum , ask oracle experts at your support!
Good luck

Single 10g Instance to RAC - without ASM migration

Is it possible to comment the following steps to convert existing 10.1.0.5 single instance database to RAC? We're using OCFS2 and it is not possible to perform ASM migration.
1. Copy the existing $ORACLE_HOME/dbs/init<SID1>.ora to
$ORACLE_HOME/dbs/init<db_name>.ora. Add the following parameters to
$ORACLE_HOME/dbs/init<db_name>.ora:
*.cluster_database = TRUE
*.cluster_database_instances = 2
     *.undo_management=AUTO (Add if you don't have it )
<SID1>.undo_tablespace=undotbs (undo tablespace which already exists)
     <SID1>.instance_name=RAC1
     <SID1>.instance_number=1
     <SID1>.thread=1
<SID1>.local_listener=LISTENER_RAC1
where LISTENER_RAC1 is an entry in the tnsnames.ora file like:
LISTENER_RAC1 =
(ADDRESS = (PROTOCOL = TCP)(HOST = <node1>)(PORT = 1521))
Keep only one line in $ORACLE_HOME/dbs/init<SID1>.ora:
ifile=$ORACLE_HOME/dbs/init<db_name>.ora
You could also create a common spfile from this pfile and add a line
like spfile=$ORACLE_HOME/dbs/spfile<db_name>.ora in each init<SIDn>.ora
file. For more details about how to do this, please refer to Note 136327.1.
2. Open your database and run $ORACLE_HOME/rdbms/admin/catclust.sql to create
cluster database specific views within the existing instance.
3. Recreate control file if you defined maxinstances to be 1 when you created
the single instance database.
To check your current setting of maxinstances, run the following command
while the database is mounted or open and connected as a user with DBA
privileges:
% sqlplus /nolog
SQL> connect / as sysdba
SQL> startup mount
SQL> alter database backup controlfile to trace;
The trace file is located in udump directory. Check the maxinstance value
in the CREATE CONTROLFILE statement. Please refer to Note 118931.1
Recreating the Controlfile in RAC and OPS
4. Add instance specific parameters in the init<db_name>.ora for the second
instance on the second node and set appropriate values for it:
     *** Names may need to be modified
     <SID2>.instance_name=RAC2
     <SID2>.instance_number=2
     <SID2>.local_listener=LISTENER_RAC2
     <SID2>.thread=2
     <SID2>.undo_tablespace=UNDOTBS2
<SID2>.cluster_database = TRUE
<SID2>.cluster_database_instances = 2
where LISTENER_RAC2 is an entry in the tnsnames.ora file like:
LISTENER_RAC2 =
(ADDRESS = (PROTOCOL = TCP)(HOST = <node2>)(PORT = 1521))
5. From the first instance, mount the database and run the following command:
     *** Path names, file names, and sizes will need to be modified
alter database
add logfile thread 2
group 3 ('/dev/RAC/redo2_01_100.dbf') size 100M,
group 4 ('/dev/RAC/redo2_02_100.dbf') size 100M;
alter database enable public thread 2;
6. Create a second Undo Tablespace from the existing instance:
     *** Path names, file names, and sizes will need to be modified
CREATE UNDO TABLESPACE UNDOTBS2 DATAFILE
     '/dev/RAC/undotbs_02_210.dbf' SIZE 200M ;
7. Set ORACLE_SID and ORACLE_HOME environment variables on the second node.
8. Start the second Instance.

In order not to affect the current home on node1, another user oracle2 is created which belong to racinstall group. On node2, which doesn’t have any oracle home installed, CRS will be installed so that node2 will become the primary node.
Been looking into this CRS for sometime as the installation has failed due to OCFS2 kernel panic upon running root.sh on the second node. Performed the cleanup as described Doc ID: Note:239998.1 (10g RAC: How to Clean Up After a Failed CRS Install), but now, the installation is failing and giving the error “ File not found /ClusterCRS/install/rootadd”. This message didn’t appear the first attempt which could indicate that the cleanup described in the note was not sufficient.

OVM 3.x: cannot migrate guests from RAC to RAC

Hi, all.
I think I have the same problem as in this other thread:
OVM 3.0.2: cannot migrate guests to updates VM servers
But the maintenance mode is off.
Rac 1 and Rac 2 - Maintenance mode is off
Migrate from Rac 1 to Rac 2 - OK
Migrate from Rac 2 to Rac 1 - don't show up as possible migration Targets
Thank you.

Hi Shawn,
In the BW 7.0 release, it is not recommended to use export datasources for the myself datamart extraction. If possible you should use a DTP & a transformation.
Please see the attached Note 989757 for further info.

How to apply archivelogs from 2 node rac to non-rac

Is there any way to apply the archivelogs from 2 node RAC to sinlge node non-rac instance while migrating RAC to non-rac.
Could anyone clarify it?
-Shanlee

There's no "different way".
Each instance in RAC write's to it's own Redo Thread -- so each has it's own set of ArchiveLogs. In the log_archive_format specification %t is the thread identifier.
Oracle needs the ArchiveLogs from both Threads of the 2 node RAC. When you issue a RECOVER DATABASE, it applies them in the correct (interleaved) sequence.
What you have to do is to ensure that the ArchiveLogs of both threads are available on the new server.

Can RAC & No RAC Coexist? + Steps towards upgrading

Given the following scenario.
server1
Oracle 10.2.0.3 running several standalone databases
server2
Oracle 10.2.0.3 running several standalone databases
Oracle 9.2.0.8 running several standalone databases
Goal:
a) Setup RAC on both servers using server1 and server2 as RAC nodes
b) Migrate 10.2.0.3 standalone databases to RAC
c) Keep 9.2.0.8 running standalone
d) Make RAC listener, most probably running from ASM home, listen to 9.2.0.8 databases request.
Would that be possible?
Which would be the steps I should take considering RDBMS is already installed on both servers?
Would I have to install Clusterware first and then ASM?
Please advise

Would that be possible? Yes it is possible. The amount of work depends on whether or not you already provisioned for shared storage and other hardware requirements (such as interconnect...)
Which would be the steps I should take considering RDBMS is already installed on both servers?You have to install the CRS first in a home of its own and then install RAC RDBMS and binaries for ASM in separate homes... I can't think of anything specific...
Would I have to install Clusterware first and then ASM?
Yes, you have to first install Clusterware (CRS) and then binaries for ASM (preferably in a separate home) and then binaries for OH.

Move ora.LISTENER.lsnr

Hi gurus,
we have an Oracle RAC 11.2.0.3 (2 nodes) in RedHat 5.3.
we had an old ORACLE_BASE with the old configuration of Oracle RAC, but we migrated some months ago for some problems and we have some parameters with /u01/app/oracle (old ORACLE_BASE) instead of /u02/app/oracle (new ORACLE_BASE).
For example:
[oracle@node1~]$ srvctl config database -d RAC -a
Database unique name: rac
Database name: rac
Oracle home: /u02/app/oracle/product/11.2.0.3/dbhome_2
Oracle user: oracle
Spfile: +DATA/rac/spfilerac.ora
Domain:
Start options: open
Stop options: immediate
Database role: PRIMARY
Management policy: AUTOMATIC
Server pools: rac
Database instances: node2,node1
Disk Groups: DATA, F_R_A
Mount point paths:
Services:
Type: RAC
Database is enabled
Database is administrator managed
[oracle@node1 ~]$ echo $ORACLE_BASE
/u02/app/oracle
but when i do
[oracle@node1~]$ /u02/app/grid/bin/crsctl stat res ora.LISTENER.lsnr -p|grep -i base
USR_ORA_ENV=ORACLE_BASE=/u01/app/oracle
[oracle@node1~]$ srvctl getenv listener
LISTENER:
ORACLE_BASE=/u01/app/oracle
so my idea is change the ORACLE_BASE doing (i look for that sentences in google and tahiti):
[oracle@node1~]$GRID_HOME/bin/crsctl modify resource ora.LISTENER.lsnr -attr USR_ORA_ENV=ORACLE_BASE=/u02/app/oracle
i saw a different form to do:
[oracle@node1~]$GRID_HOME/bin/srvctl setenv listener -l LISTENER -t "ORACLE_BASE=/u02/app/oracle"
with form is the correct, or i must do both? should i restart the listener after execute it? or restart database?
sorry for my bad english and thanks for help.

Both are same and cane be used, but usually we use srvctl for LOCAL resource and crsctl for GLOBAL resources.
Since LISTENER is running on both the nodes and is a LOCAL resource,so suggest to use srvctl.
Also it can be done with following:
srvctl modify listener -l LISTENER -o /u01/app/oracle/product/11.2.0/dbhome_1
Oracle_home is /u01/app/oracle/product/11.2.0/dbhome_1 in my case
with form is the correct, or i must do both? should i restart the listener after execute it? or restart database?
Both method are not required. Restart of DB is not required but listener is.

How to migrate data from oracle 9i database to new machine 11gr2 RAC ASM

Hi Expert
I need your expertise to advise me what is the best method to move data from oracle 9i database to new machine running oracle 11r2 RAC database with ASM.
Currently my production server running on HPUX ORACLE 9I database with normal file system. My new server is running SUN SOLARIS SPACR 64 bit ORACLE 11gr2 RAC with ASM. What is best method to move data over so it will be consistent. Any guide can refer.
Regard
William

Hi William,
See the note in metalink Migration of Oracle Database Instances Across OS Platforms [ID 733205.1] to saw the Endian Format of your OS. If is the same you can use the RMAN to convert the database to another OS, if not the only option is using export/import (Transportable Tablespaces).
To upgrade from 9i to 11g, see the note 837570.1 - Complete Checklist for Manual Upgrades to 11gR2.
To migrate your FS to ASM the only way is using RMAN, so see the note - How to move a datafile from a file system to ASM [ID 390274.1].
Hope this help you.

Ruben Morais

Oracle 10g RAC Database Migration from SAN to New SAN.

Hi All,
Our client has implemented a Two Node Oracle 10g R2 RAC on HP-UX v2. The Database is on ASM and on HP EVA 4000 SAN. The database size in around 1.2 TB.
Now the requirement is to migrate the Database and Clusterware files to a New SAN (EVA 6400).
SAN to SAN migration can't be done as the customer didn't get license for such storage migration.
My immediate suggestion was to connect the New SAN and present the LUNs and add the Disks from New SAN and wait for rebalance to complete. Then drop the Old Disks which are on Old SAN. Exact Steps To Migrate ASM Diskgroups To Another SAN Without Downtime. (Doc ID 837308.1).
Clients wants us to suggest alternate solutions as they are worried that presenting LUNs from Old SAN and New SAN at the same time may give some issues and also if re-balance fails then it may affect the database. Also they are not able to estimate the time to re-balance a 1.2 TB database across Disks from 2 different SAN. Downtime window is ony 48 hours.
One wild suggestion was to:
1. Connect the New SAN.
2. Create New Diskgroups on New SAN from Oracle RAC env.
3. Backup the Production database and restore on the same Oracle RAC servers but on New Diskgroups.
4. Start the database from new Diskgroup location by updating the spfile/pfile
5. Make sure everything is fine then drop the current Diskgroups from Old SAN.
Will the above idea work in Production env? I think there is a lot of risks in doing the above.
Customer does not have Oracle RAC on Test env so there isn't any chance of trying out any method.
Any suggestion is appreciated.
Rgds,
Thiru.

Downtime window is ony 48 hours.Adding and removing LUNs online is one of the great features of ASM. The Rebalance will be perfomed under SAN. No downtime!!!
If your customer is not entrusting on ASM. So Oracle Support can answer all doubt.
Any concern .. Contat Oracle Support to guide you in the best way to perform this work.

ASM Supports many Terabytes, if you need to migrate 3 Database with 20TB each using this way described above would be very laborious .. .. So add and remove Luns online is one feature that must work.
Take the approval from Oracle support and do this work using the ASM Rebalance.

Rconfig fails for migrate single ASM instance to Oracle RAC 11.2.0.3

We completed the following steps thus far to migrate single instance with ASM 11.2.0.3 on Oracle Linux to RAC:
1. Install RAC CRS 11.2.0.3 in GRID_HOME
2. Install RAC database 11.2.0.3 software in new ORACLE_HOME
3. Added ASM diskgroups to two node ASM instances
4. run rconfig from target RAC ORACLE_HOME
It fails on:

Migrate Oracle Rac 11.1.0.6 SE to Oracle Rac 11.2 EE

Hi,
is there some guideline to migrate e 11.1.0.6 RAC Standard Edition with ASM to a 11.2.0 RAC Enterprise Editon?
Database is almost 800gb, index included.
Some best practice? Some suggestion? Some links?
Thanks in advance,
Samuel Rabini

Or from 11.1.0.6 Standard to 11.1.0.6 Enterprise.
I can find anything on internet to do such a migration.
Thanks in advance.

9.2.0.8 singleInstance migration to 11.2.0.2 RAC 2xnode

Hi,
Good Day!
We have A scenario of database upgrade + migration.
Detail are provided below:
Current plateform - 1xnode:
HPUX 11.11
Database 9.2.0.8 SingleInstance
Migrated Plateform - 2xnode 'new nodes':
HPUX 11.31
Database 11.2.0.2 RAC
In totality we have *3 servers, 1 in production and 2 spare*.
A straight forward way to accomplish it is to copy the offline backups to one of the new servers, Upgrade to 11.2.0.2 and Convert single instance 11.2.0.2 to RAC 11.2.0.2.
During this activity DOWNTIME = OFFLINE-DB Backups Copy to Remote Node + Upgrade-Time.
Purpose of sharing the above scenario in Data Guard forum here is to discuss and to conclude any way to reduce that DOWNTIME and cover the risks Using Data Guard / Oracle MAA.
As far as i know, 11gR2 Data Guard did'nt support 9iR2 to 11gR2 DataGuard Configuration, then how can we take benefit of Oracle MAA for above DB-Upgrade and Migrate activity to minimize the downtime?
Regards,

You are correct. You cannot use Data Guard to get from 9i to 11.2 directly. At http://www.oracle.com/technetwork/database/features/availability/ha-casestudies-098033.html you will see a couple of case studies at the bottom using Transportable Tablespaces to move across versions and in some cases platforms with little downtime.
Otherwise you best bet would be to use GoldenGate to replicate to a 11.2 target you created and then move production to that target when it was caught up.

How to migrate DB from single node 10gR2 to RAC 11gR2 on diff platform?

How to migrate DB from single node 10gR2 to RAC 11gR2 on different platform with possible minimum downtime? We have a situation of upgrade/migrate oracle 10gR2 single instance DB to 2-node RAC 11gR. The source OS is Solaris 10 on SPARC and the target OS is Linux (the target servers could be changed to Solaris 11 x86 if needed). What is the best solution on that?
Thanks,

Technically, can do the following for upgrading and migration?
1. Create 11gR2 oracle home on the same server and upgrade the database from 10gR2 to 11gR2 by running conversion (2 hour down time?)
2. Set up Heterogeneous Primary and Physical Standbys by RMAN. The standby is the RAC with ASM. No need down time. (from Solaris Space to Linux - this may be a problem)
3. At the cutoff time, activate the standby DB from the RAC ASM.
If feasible, do we have some detail guild line for each step?
