Implementing 11gR2 RAC with dataguard

Could any one provide the steps on how to setup 11gR2 two node RAC With Dataguard . Could the 11R2 Active database duplication can be used in setting up the standby ?
I just need the order of steps to be followed to set up the environment.
1] Set up the Grid Infrsatructure for the 2 node RAC .
2] Create the database .
3] Modify the init.ora prameter to chage the above created database as primary .
4] Set up the grid infrastructure for the 2 node RAC on the DR site.
5] Create the standby database using 11gR2 active database dupication.
Is the above order correct ? If not , let me know the correct order of steps that needs to be followed to setup 11gR2 RAC with dataguard.

starting from 11gR2 you can use duplication from active database. also refer below note.

Implemeting 11gR2 RAC with Data Guard

Hi ,
Could any one provide the steps on how to setup 11gR2 two node RAC With Dataguard . Could the 11R2 Active database duplication can be used in setting up the standby ?
I just need the order of steps to be followed to set up the environment.
Thanks,

Hi Fiedi ,
Thanks for the reply .
I know how to build the oracle dataguard . But , I'm looking for the order of steps that I need to follow to build 11gR2 RAC with data guard.
1] Set up the Grid Infrsatructure for the 2 node RAC .
2] Create the database .
3] Modify the init.ora prameter to chage the above created database as primary .
4] Set up the grid infrastructure for the 2 node RAC on the DR site.
5] Create the standby database using 11gR2 active database dupication.
Is the above order correct ? If not , let me know the correct order of steps that needs to be followed to setup 11gR2 RAC with dataguard.

How to convert single instance10g db to 11gR2 RAC with ASM

Hi,
I need your help to decide the plan about how to convert single instance 10g database to 11gr2 rac with asm.
I can have about 6 to 8 hours of downtime to upgrade and move to rac with asm.
db size is about 1.5tb and on AIX.
here is my plan....
1) install 11gr2 rac with asm on two nodes
2) verify rac installation and clustered asm
3)install 10g oracle binaries( yes 10g )
4) shutdown production db ( machine prod )
5) make copy of production and restore on 1st node ( using shadow image , so it's quick and its file system )
6) upgrade db to 11g ( still of file system )
7) after successful upgrade, move to asm ( rman backup )
8) add another node
does it look okay ? OR is there a better approach to save time?
can someone help me ?
Thanks...

Thanks ...
So here is what I thought... suggest if something is not right...
1) install 11gr2 grid infra on node A and B with ASM
2) stop CLUSTER ON BOTH NODES.
3) shutdown prod db on 10g ( downtime starts )
4) take rman cold backup
5) restore rman backup on node A on ASM ( as if single instance 11g , no rac parameters )
6) mount and run upgrade script for 11g, then open db with 11
7) after successful upgrade, shutdown db node A
8) change all rac related parameters, spfile,undo,redo for rac environment on both nodes
9) open db in rac environment
can I do this way ?
My only question is, even though I installed rac on node A and B, in step 5 and 6 I'm using only node A as if it is single instance. Is it possible ?
if it is then I'm good to go...
Thanks for all suggestions.

EPB and DBI on RAC with Dataguard

Hello all,
I was wondering if anyone has installed and configured EPB and DBI on a
- Apps 11.5.10.2,
- Oracle Server 10.1.0.4 instance on
- Red Hat AS 4,
- HP Proliant,
- 2 noded RAC cluster
- Dataguard (in physical mode) as a DR solution.
Please let me know if you were able to get this particular configuration up and running and what issues you ran into.
Thanks
Steve

Hi,
Im also keen to here of anyone with similar build for EPB and DBI Implementation ?

Oracle 11gR2 RAC with Sun clsuter 3.3 clsetup not showing ASMDiskGroup RS

Hello,
I am installing Oracle 11gR2 RAC on Solaris cluster 3.3 with hardware RAID and ASM
I was able to register rac-famework-rg and crs-framework-rg.
Oracle RAC is up and running (confirmed from crs_stat -t -v)
However, while creating option 5. Automatic Storage Management (ASM) on clsetup, I was getting ERROR: ASM is either not installed or the installation is invalid!
I have created the asm-inst-rg with resource asm-inst-rs and asm-dg-rg with resources asm-dg-fra, asm-dg-data and asm-dg-crs using CLI. Please find the complete clrg and clrs status output below:
root@rac1 # clrg status

Once I reach clsetup option 6: Resources for Oracle Real Application Clusters Database Instances, I was able to select cluster db name, oracle home, SID for both nodes, and it listed the asm-inst-rg and asm-inst-rs for selection of "Specify Oracle ASM Instance Resource".
The problem is the the next selection which is "Specify Oracle ASM Disk Group Resources" which does NOT list any asm-dg-rg or asm-dg-fra or anything, instead, it throws error "No existing disk-group resources available for selection. Run ASM subwizard create new resource(s) and come back to this panel for the selection."
Kindly guide me to create Resources for Oracle Real Application Clusters Database Instances either in CLI or clsetup
Thanks and Regards

Solaris Cluster 3.3 u1 solved the issue.
The problem right now I am facing is IPMP on the public interface.
When I remove the cable on the bge0, the ip on bge0 and the SCAN IP's are plumbed to bge1 which is in sc_ipmp0, but NOT the virtual IP!!! and the listeners on both nodes go offiline!!!
any inputs on the configuration will be highly appreciated..

TNS-12520 when connecting via TCPS on 11gR2 RAC with SCAN Listener

I am struck trying to implement TCPS on our Oracle RAC SCAN Listener. I have added to our Oracle 12c systems, but not on a RAC with SCAN.
I created a wallet and certificate on one of the nodes, and copied it to the node and created auto login on each node. I exported the trust.jks and identity.jks, and loaded them in my test java program as the trust store and key stores. I have added the wallet location to the listener tns and sql ora files.
When attempting a TCPS connection, the ssl handshake succeed, but the client reports error:
ORA-12520, TNS:listener could not find available handler for requested type of server
The nodes scan listener log reports the TNS error, listener_scan1/alert/log.xml, when the connection is using TCPS on port 2484:

Hi hitgon,
Thanks first.
The commands output are as the following:
Command: srvctl status listener
Output:
# Listener LISTENER is enabled
# Listener LISTENER is running on node(s): rac1,rac2
Command: srvctl status scan_listener
Output:
# SCAN Listener LISTENER_SCAN1 is enabled

Output:
# ERROR:

# Enter user-name:
By the way, rac-scan is the host where the SCAN listener is running and rac.localdomain is the service name. I've also tried the following commands
with the same error output:
sqlplus username/passwd@RAC
At last, i think the output of "lsnrctl status LISTENER_SCAN1" might help:

Oracle 11gR2 RAC with ASM with asm_preferred_read_failure_group

Hello DBAs,
I apologize first if this question has been posted somewhere.
I have a two nodes cluster so essentially, I have 2 ASM instances (ASM1 & ASM2). It seems like both instances share the same ASM spfile.
+ASM1> show parameter spfile;
NAME TYPE VALUE
spfile string +OCRDG/clone-cluster/asmparame
terfile/registry.253.759424467
=====================================
+ASM2> show parameter spfile;
NAME TYPE VALUE
spfile string +OCRDG/clone-cluster/asmparame
terfile/registry.253.759424467
The Oracle docs says that you can configure asm_preferred_read_failure_group for each instance so when I logged in instance 1, I ran the command:
+ASM1> alter system set asm_preferred_read_failure_groups='DATA.FG1', 'DATA.FG2';
then it showed DATA.FG1 is primary and DATA.FG2 is secondary but this also shows on instance 2 because it uses the same spfile.
How can I make instance 1 uses DATA.FG1 for primary and instance 2 uses DATA.FG2 for primary. I have separate GRID home for each node.
Any help is much appreciated.
thanks,
TD

then it showed DATA.FG1 is primary and DATA.FG2 is secondary but this also shows on instance 2 because it uses the same spfile.
How can I make instance 1 uses DATA.FG1 for primary and instance 2 uses DATA.FG2 for primary. I have separate GRID home for each node.
Any help is much appreciated.Normally we can give different values for each instance, But i never tried in ASM.
Here is example
SQL> alter system set asm_preferred_read_failure_groups='DATA.FG1' sid='ASM1';
SQL> alter system set asm_preferred_read_failure_groups='DATA.FG2' sid='ASM2';So DATA.FG1 will be allocated to ASM1, DATA.FG2 will be allocated to ASM2.
Now check from ASM1
SQL> show parameter asm_preferred_read_failure_group
& from ASM2
SQL> show parameter asm_preferred_read_failure_group

TAF with FAN in oracle 11gr2 RAC

dear all,
our enviornment is 11GR2 RAC with 2 ndoe RAC. it has four different applications accessing the database.
so for each application i have created services as A,B,C,D.
services in NODE1- Prefered service in NODE2 -Prefered
A B
C D
services in NODE1- available service in NODE2 -Available
B A
D C
now i have the services as described above.
each services are created with
srvctl add service -d DB -s A -r NODE1 -a NODE2 –P BASIC –y AUTOMATIC
srvctl modify service -d DB -s A -q TRUE -P BASIC -e SELECT -z 180 -w 5 -j LONG
srvctl start service -d DB -s A
now i have enable server-side TAF with FAN. so do i need to provide the TNS entries to application layer namely oracle client
as below
AP =
(DESCRIPTION =
(ADDRESS=(PROTOCOL=TCP)(HOST=cluster01-scan)(PORT=1521))
(LOAD_BALANCE = YES)
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = TEST)
(FAILOVER_MODE =
(TYPE = SELECT)(METHOD = BASIC)(RETRIES = 180)(DELAY = 5))))
or
do i need to add the above TNS entries in serverside tnsnames.ora file?
1) the connection from jdbc thin or session established via JDBC thin is not having the TAF details in v$session view.
SELECT machine, failover_method, failover_type,
failed_over, service_name, COUNT(*)
FROM v$session
GROUP BY machine, failover_method, failover_type,
failed_over, service_name;
if i execute the above query i couldnt find any session is having failover_method as BASIC and FAILOVER_TYPE as select.
all my application tier is using JDBC thin to access the database.
if i use oracle client from application server to access the database i could see my session having FAILOVER_METHOD as BASIC and FAILOVER_TYPE as SELECT.
so please provide me any realtime example for accessing database using JDBC thin with TAF and FAN properties for their sessions.

Hi,
1.) No if you define a service with TAF, then the TAF information will be provided to the client, without having to specify it again in the TNSNAMES.ora (neither client nor server).
However it does not hurt, if you have specified it additionally (it just makes it more difficult if you want to change something, because the client side does not get updated).
See this whitepaper for more information:
http://www.oracle.com/technetwork/database/clustering/overview/awm11gr2-130711.pdf
2.) However it seems you have forgotten to specify something with the service (you seem to be missing -m):
srvctl add service -h
Adds a service configuration to the Oracle Clusterware.
-P {NONE | BASIC | PRECONNECT} TAF policy specification
-e <Failover type> Failover type (NONE, SESSION, or SELECT)
-m <Failover method> Failover method (NONE or BASIC)
-w <integer> Failover delay
-z <integer> Failover retries

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.
Best Regards,
Ruben Morais

ASM vs RAID for 11gR2 RAC Environment

Hi There!
We are planning to install 11GR2 RAC with two nodes Cluster on LINUX in Our Environment.
Operating System: OEL 5.4
In our hardware we got two dell Servers with 16GB RAM on each plus On SAN side we have only 8 disk (173GB) left for RAC Cluster Setup. I am going to create to database (LIVE/UAT) on This Cluster Setup. Currently Our Production DB size is 6GB and I assume for coming 5 year it will not go beyond 100GB And I keep UAT size 15GB fix with No changes.So how you get the best ASM performance by using my all Resources.
My question:
1)     Which is best solution for ASM and RAID in our storage Environment?
2)     How many Disk group I Create for Both Databases (UAT/LIVE)?
3)     How many disks should I allocate in Each Disk Group with which RAID Option or if any suggesting for LUN, How do I create LUNS across the Disk which I got?
4)     I know oracle recommended Two DISK Group DATA&FRA is there any other suggestion for CRS, REDO, and TEMP FILE?
Thanks for your Assintance.
Hemesh.

My first question was : Which RAID Option(0,1,5,0+1) I choose with ASM ?Well, it doesnt matter for ASM. At least in your configuration with 8 disks.
RAID0is not an option - forget about it. RAID1 (or combined with more than two disks and an overlayed RAID0 which makes an RAID 1+0) might be an option for write-intensive databases. RAID5 is more for read-intensive due to the RAID5-write-hole but offers "more" capacity at the cost of slower write speed.
I recommended to stick with RAID1 (thus mirroring two disks) and exporting them to ASM rather than creating one big RAID1+0 over all of your disks and exporting the storage as one big chuck to ASM for manageability. If you want to add storage lateron your perfect in line with Oracles recommendations to have equal size LUNs in ASM with two mirrored disks. If you create on big RAID 1+0 and lateron add two disks you have a LUN of 600 GB size and one of 170 GB size...thats a big mismatch.
But If i create TWO disk group then, is there good practice to offer them to both (UAT/LIVE) databases.?Normally there is a separation between UAT and P on storage and on server level. In your case it might be "ok" to place everything in the same disk group. This mainly depends on which database puts the most load on the disk subsystem.

Oracle 11gR2 RAC setup with ASM option running on two nodes . Seeking help

Hi ,
Recently we have migrated to 11gR2 extended RAC for one of our application using ASM . Its a two node RAC setup . We are using ASM Normal redundancy feature maintaining two failure group .
I need few clarification regarding our new DR set up .
We are planning to have EMC SRDF replication from any of node storage ( Either 1 or 2) to the DR disks .
Its stright to use when we use the normal file systems . In case of ASM , I am not sure how this replication will work ? and on which level the replication should happen ?
Do i need an ASM instance up and running on DR server , Which will recognize the disks as it is once DR disks are separated from prod replication and assigned to the server ?
What should be prerequisite on DR server before we can start the srdf replication (EMC) and make it work .
Thanks for All your Valuble suggestion .

Before you decide to use EMC replication give considerable thought to the fact that you are introducing a single point of failure.
Hardware snapshot replication is very fast. That is all it is. If you database crashes because of corruption on disk ... your replica will be equally corrupt.
What is fast can not do what DataGuard does ... verify quality. If the point is DR. Go with DataGuard unless EMC is willing to, in writing (not verbally) give you a guarantee (in hard cash) to cover all costs if they replicate bad blocks and it causes an outage.
And just so no one thinks I'm picking o EMC ... the same weakness exists with all of the other storage vendor's products.

Oracle 11gR2 RAC in LDOM Network issue

Hi, Requesting your expert advise regarding this configuration.
We are implementing LDOM 2.2 on two SPARC T4-4 for Oracle 11gR2 RAC; Solaris 10 U10 on both control and guest domain. The setup for each primary/control domain is: Two 10g links aggregated and have four VLAN trunked on the aggregate. vSwitch created using the aggr as the device as following per T4-4:
NOTE: VLAN 1501 is for data connection and VLAN 10 is for heartbeat for one RAC cluster and VL 1601 and 11 is for another RAC. all together four LDOMS.

Yes, I can connect to the vswitch interface on the control domain. I didn't specify any PVID because my understanding is that PVID will tag any frame with the PVID VLAN by default. basically the PVID for this interface is 1.
Here's the VNET config for the other LDOM in the RAC cluster:
