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.

Reinstalling Oracle 11gR2 RAC Grid Problem - ASM Disks Group
Folks,
Hello.
I am installing Oracle 11gR2 RAC using 2 Virtual Machines (rac1 and rac2 whose OS are Oracle Linux 5.6) in VMPlayer.
I have been installing Grid Infrastructure using runInstaller in the first VM rac1 from step 1 to step 9 of 10.
On the step 9 of 10 in the Wizard, accidentally, I touch the Mouse, and the Wizard is gone.
The directory for installing Grid in the 2 VMs is the same: /u01
In order to make sure everything is correct, I delete entire directory /u01 in the 2 VMs and install Grid in rac1 again.
I have understood it's not the right way to delete /u01. The right way is to follow the tutorial
http://docs.oracle.com/cd/E11882_01/install.112/e22489/rem_orcl.htm#CBHEFHAC
But I have deleted /u01 and need to fix one by one. I install Grid again and get the error message on step 5 of 9 as follows:
[INS - 30516] Please specify unique disk groups.
[INS-3050] Empty ASM disk group.
Cause - Installer has detected the disk group name provided already exists on the system.
Action - Specify different disk group.
In Wizard, the previous Disk Group name is "DATA" and its Candidate disks (5 ASMDISKs) are gone. I try to use a different name "DATA2", but no ASMDISKs come up under "Candidate disks". For "ALL Disks", all ASMDISKs cannot be selected.
I want to use the same ASM disk group "DATA" and don't want to create a new disk group.
My question is:
How to have the previous ASM disks and its group "DATA" come up under "Candidate Disks" so that can use it again ?
Thanks.Hi, in case this helps anyone else. I got this INS-30516 error too was stumped for little while. I have 2 x 2-node RAC which are hitting same SAN. The first-built RAC has a DATA diskgroup. When went to build second RAC on new ASM disk new DIskgroup (but same diskgroup name DATA) got INS-30516 about diskgroup name already in use etc. Finally figured out all that was required was to restrict diskstring using button in installer to only retrieve the LUNS for this RAC (this was quick and dirty - all LUNS for both RAC being presented to both RAC). Once diskstring only searched for the LUNS required for this RAC only, e.g.
ORCL:DATA_P* (for DATA_PD and FRA_PD)
the error went away.
I also have DATA_DR and FRA_DR presenting to both RAC. Apparently it scans the header and if it finds a diskgroup name that is already in use based on the diskstring scan it will not allow reuse of the diskgroup name since it has no way of knowing that the other ASM disks are for a different RAC.

Oracle 11gR2 RAC problem with resource state
Hi all,
I installed Oracle 11gR2 grid infrastructure with 2 nodes and I installed DB 11gR2.
S.O: HP-UX
I actived both DB instance in each node.
For an hardware problem node 1 become unstable (continuos auto reboot).
I found that the problem was RAM.
However I note that database resource is in a particular state and i don't able to reset it.
Performing command crsctl status resource ora.orcl.db this is the result
ora.orcl.db
1 OFFLINE UNKNOWN node1 Startup Initiated
2 ONLINE ONLINE node2 Open
That UNKNOWN state is really abstruse.
I tryed to perform crsctl stop resource ora.orcl.db -n node1 and the result is
CRS-2679: Attempting to clean 'ora.orcl.db' on 'node1'
ORA-01034: ORACLE not available
ORA-27101: shared memory realm does not exist
HPUX-ia64 Error: 2: No such file or directory
Process ID: 0
Session ID: 0 Serial number: 0
CRS-2680: Clean of 'ora.orcl.db' on 'node1' failed
CRS-4000: Command Stop failed, or completed with errors.
I tryed to perform crsctl start resource ora.orcl.db -n node1 and the result is
CRS-2662: Resource 'ora.orcl.db' is disabled on server 'node1'
CRS-4000: Command Start failed, or completed with errors.
How do I do to reset that UNKNOWN state?
Thanks in advance.
Bye
AlessandroI tryed srvctl enable instance -d orcl -i ORCL_1
but the results is
srvctl enable instance command is not supported for configuration using server pool.
I tryed to delete service ora.orcl.db and recreate it.
Now I have
NAME=ora.orcl.db
TYPE=ora.database.type
TARGET=ONLINE , ONLINE
STATE=UNKNOWN on node1, OFFLINE
So Targets are both ONLINE, but if I write crsctl start resource ora.orcl.db
the result is
CRS-2679: Attempting to clean 'ora.orcl.db' on 'node1'
CRS-2672: Attempting to start 'ora.orcl.db' on 'node2'

Where DB_UNIQUE_NAME attribute must be set?
Any other suggest?

Oracle 10g RAC design with ASM and OCFS
Hi all,
I have a question about a proposed Oracle 10g Release 2 RAC design for a 2 node cluster.
ASM can store database files but not Oracle binaries nor OCR and voting disk. As such, OCFS version 1 does not support a shared Oracle Home. We plan to use OCFS version 2 with ASM version 2 on Red Hat Linux Enteprrise Server 4 with Oracle 10g Release 2 (10.2.0.1).
For OCFS v2, a shared Oracle home and shared OCR and voting disk are supported. My question is does the following proposed architecture make sense for OCFS v2 with ASM v2 on Red Hat Linux 4?
Oracle 10g Release 2 on Red Hat Enterprise Linux Server 4:
OCFS V2:
- shared Oracle home and binaries
- shared OCR and vdisk files
- CRS software shared OCFS v2 filesystem
- spfile
- controlfiles
- tnsnames.ora
ASM v2 with ASMLib v2:
Proposed ASM disk groups:
- data_dg for application data
- backupdg for flashback and archivelogs
- undo_rac1dg ASM diskgroup for undo tablespace for racnode1
- undo_rac2dg ASM diskgroup for undo tablespace for racnode2
- redo_rac1dg ASM diskgroup to hold redo logs for racnode1
- redo_rac2dg ASM diskgroup to hold redo logs for racnode2
- temp1dg temp tablespace for racnode1
- temp2dg temp tablespace for racnode2
Does this sound like a good initial design?
Ben Prusinski, Senior DBAOK Tim, thanks for advices.
I think Netbackup can be integrated with RMAN but I don't want to loose time on this (political).
To summarize:
ORACLE_HOME and CRS_HOME on each node (RAID1 and NTFS)
Shared storage:
Disk1 and disk 2: RAID1: - Raw partition 1 for OCR
- Raw partition 2 for VotingDisk
- OCFS for FLASH_RECOVERY_AREA
Disk3, disk4 and disk5: RAID 0 - Raw with ASM redundancy normal 1 diskgroup for database files.
This is a running project here, will start testing the design on VMware and then go for production setup.

Oracle 11gR2 RAC installation with DNS
Dear Guru's,
I want to configure RAC on two node cluster with DNS(For SCAN) in my testing server.
O.S: RHEL5.4(64 bit)
Oracle Version: 11gR2(11.2.0.2)
Note: Am creating nodes in VMware ESXi server.
Just I want to know whether DNS should be configure in any one of those NODES or in separate machine.
Bala :)Hi Bala,
I want to configure my Database with & without DNS. (Will try both installation in different servers)I think, you have already received a link on very good article about Oracle RAC installation without DNS and DHCP (I mean Jeffrey Hunter's article).
There is one more about Oracle RAC installation with DNS and DHCP (http://gjilevski.com/2011/10/05/build-two-node-oracle-rac-11gr2-11-2-0-3-with-gns-dns-dhcp-and-haip/).
And want to know how it forwards the client connection if a node fails.. Can anyone update the URL for this..There are a lot of information about it:

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:

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
Ushas SymonSolaris 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..

Oracle 11gR2 RAC: Running the script root.sh problem
Folks,
Hello. I am installing Oracle 11gR2 RAC using 2 Virtual Machines (rac1 and rac2 whose OS are Oracle Linux 5.6) in VMPlayer and according to the tutorial
http://appsdbaworkshop.blogspot.com/2011/10/11gr2-rac-on-linux-56-using-vmware.html
I have been installing Grid Infrastructure using runInstaller from step 1 to step 9 of 10 in both VM rac1 and rac2.
Now, I am running the script root.sh in VM rac1 and rac2 as below:
[root@rac1 /]# /u01/app/grid/root.sh
Output:

Failed to start ASM.
Failed to start Oracle Clusterware Stack.
[root@rac2 /]#
As we see the output above, rac1 and rac2 get the same problems. in addition, rac2 fails to start ASM and Clusterware stack. Thus, I have 2 questions:
First, the common problem for rac1 and rac2 :
1)Module "oracleoks, oracleadvm, oracleacfs" not found
2)/dev/asm/.asm_ctl_spec not detected
3)ADVM/ACFS installation failed
Do the above 3 factors affect Grid and DataBase Installation later ? If yes, how to solve these problems ?
Second, how to start ASM and Clusterware stack in rac2 ?
Thanks.you have 2 options:
1. OEL 5.6 comes with 2 kernels, the original Red Hat, and Oracle UEK, you can choose not to use UEK
or the one i would recommend:
2. Upgrade Grid Infrastructure,
*11.2.0.3.1* (patch 13348650, released about a 1 month ago) supports ACFS on UEK (starting with 2.6.32.200 IIRC) -
Environment:
Oracle 11gR2 RAC (2 node) with ASM
HP-UX B.11.31 U ia64
We have configured two ASM disk group for Data & FRA, and we configured RMAN backup into FRA location. Now our Database, Log file, Archive logs and RMAN backup files all are in ASM on primary site.
Our network team is using Recover Point to mirror all the disks into DR site; we have no setup from Oracle side. What is the possible configuration that we need to have in DR site from Oracle side in order to bring-up the database in-case of primary site failure (disaster).
I am new to Oracle RAC can some one give me a suggestion.

Oracle 10g R2 installation with ASM+RAC
Gurus,
Need some suggestuon on Oracle 10g R2 installation with ASM and RAC option.
We have found many documents on the Oracle, HP, HP-Oracle CTC and third party web sites, but nothing that is specific to this particular combination of separate
ORACLE_HOMEs, ASM and 10g RAC CRS. It is unclear for me from the documentation how this combination of ASM and 10.2g RAC may best be installed.
The high level steps i got after reading lot of docs as follows - but i am not sure whether these are correct or not. if they are correct, can any one share their experience/notes please?
1) Install CRS
2) Install RDBMS for ASM HOME - create separater oracle home for ASM instance using OUI
3) Install RDBMS for RAC Database Home - create separater oracle home for RAC database using OUI
4) Create ASM database using DBCA -
5) Use dbca to create database.Oracle provides 'paint by numbers' tutorials called 'Oracle By Example'. (Go to OTN, check under the Training tab)
They have one for a Windows based ASM/RAC that you might want to review. Not your specific environment, but the steps will be dag-nabbed close.
I recommend walking the path (http://otn.oracle.com >> training:OBE >> Database 10g Release 1:VMWare:Installation
http://www.oracle.com/technology/obe/obe10gdb_vmware/install/racinstallwin2k/racinstallwin2k.htm -
Oracle 11gR2 RAC clusterware not picking up ASM diskgroups
Hello: I had to deinstall a failed oracle 11gR2 rac cuslterware. But, not the asm disks are not in the OUI pick list. How can I resolve that?
The storage is on SAN partitions.Probably the install already put something on the disks.
Clean them with dd if=/dev/zero of=<your asm disks> bs=1M count=10

The best option to create a shared storage for Oracle 11gR2 RAC in OEL 5?
Hello,
Could you please tell me the best option to create a shared storage for Oracle 11gR2 RAC in Oracel Enterprise Linux 5? in production environment? And could you help to create shared storage? Because there is no additional step in Oracle installation guide. There are steps for only asm disk creation.
Thank you.Here are names of partitions and permissions. Partitions which have 146 GB, 438 GB, 438 GB of capacity are my storage. Two of three disks which are 438 GB were configured as RAID 5 and remaining disk was configured as RAID 0. My storage is Dell MD 3000i and connected to nodes through ethernet.

Installing Oracle 11gR2 RAC Problem: ASM disks
Folks,
Hello. I am installing Oracle 11gR2 RAC using 2 Virtual Machines (rac1 and rac2 whose OS are Oracle Linux 5.6) in VMPlayer and according to the tutorial
http://appsdbaworkshop.blogspot.com/2011/10/11gr2-rac-on-linux-56-using-vmware.html
At the first time, I create VM rac1. While its OS Oracle Linux 5.6 is booting, initializing ASMLib Driver OK. I create 5 ASM disks successfully using the command:
[root@rac1 /]# /etc/init.d/oracleasm createdisk ASMDISK1 /dev/sdb1
Output: Marking disk "ASMDISK1" as an ASM disk: OK
Because the hard disk space of rac1 is not enough to install Database, I create VM rac1 again with bigger hard disk space (30GB). I do everything the same with that at the first time. But this time, While OS Oracle Linux 5.6 is booting, initializing ASMLib Driver failed. I create 5 ASM disks using the same command:
[root@rac1 /]# /etc/init.d/oracleasm createdisk ASMDISK1 /dev/sdb1
Output: Marking disk "ASMDISK1" as an ASM disk: failed
But when I use the command:
[root@rac1 /]# /etc/init.d/oracleasm listdisks
Output: ASMDISK1 ASMDISK2 ASMDISK3 ASMDISK4 ASMDISK5
My questions are:
First, can the 5 disks "ASMDISK1 ASMDISK2 ASMDISK3 ASMDISK4 ASMDISK5" be used correctly in spite of Marking disk "ASMDISK1(2 3 4 5)" as an ASM disk failed ?
Second, how to fix OS Oracle Linux 5.6 so that initializing ASMLib Driver OK while booting ?
Thanks.Folks,
Hello. The issue is solved by myself. Thanks. -
Oracle 11gR2 RAC VM and SCAN and DNS and /etc/hosts (two) setup questions
Hi,
I am looking forward to setting up two Oracle 11gR2 RAC instances
on my Oracle VM test machine.
I plan on using the Oracle 11gR2 RAC VM template.
I want the final Oracle 11gR2 RAC instances to have SCAN that uses DNS.
The DNS will be pre-installed in the JeOS.
My first simple question about the setup is the following.
In my DNS name file, for example,
/var/named/chroot/var/named/milkyway.univ.db
do I need to provide the racnode1 and racnode2 information,
for example,
# DNS name file (snippet)
myjeos IN A 192.168.1.150
racnode1 IN A 192.168.1.161
racnode1-vip IN A 192.168.1.163
racnode2 IN A 192.168.1.162
racnode2-vip IN A 192.168.1.164
rac-scan IN A 192.168.1.131
rac-scan IN A 192.168.1.132
rac-scan IN A 192.168.1.133
Or, can I just provide only the rac-scan information
# DNS name file alternate (snippet)
myjeos IN A 192.168.1.150
rac-scan IN A 192.168.1.131
rac-scan IN A 192.168.1.132
rac-scan IN A 192.168.1.133
What I am getting at is the following.
Within the install process, will racnode1, racnode1-vip, racnode2,
and racnode2-vip host names and their IP address be written
to the RAC instances /etc/hosts files? (So I should not bother
to put them in the DNS name file like '# DNS name file alternate (snippet)'?)
Or, should I put the racnode and racnode-vip host names and IP addresses
in the DNS name file like '# DNS name file (snippet)'?
The second question is the following.
Are the cluster name and the scan name allowed to be different?
Currently, I would plan them to be different,
for example, rac-cluster and rac-scan.
Or, are they required to be the same,
for example, rac-cluster and rac-cluster.
Thank you.

Or, can I just provide only the rac-scan information You need to provide all of it in DNS, because other hosts in your network will need to be able to resolve all of the normal, VIP and SCAN addresses for your RAC nodes. We write this data out to /etc/hosts just to reduce the amount of round-trip DNS requests the cluster nodes make for themselves.
Are the cluster name and the scan name allowed to be different?They can be different. -
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.
ldm add-vswitch vid=1501,1601,10,11 net-dev=aggr1 primary-vsw0 primary
ldm add-vnet pvid=1501 vnetprod primary-vsw0 guest1

ldm add-vnet pvid=1601 vnetprod primary-vsw0 guest2
ldm add-vnet pvid=11 vnethb primary-vsw0 guest2
vnet inside the LDOM are not tagged:

Here's the VNET config for the other LDOM in the RAC cluster:

Oracle 11gR2 RAC Backup & Recovery
I am new to Oracle RAC, I have installed Oracle 11gR2 RAC (2 node) on HP-UX with ASM, configured FRA location on ASM.
Now I would like to configure RMAN backup, Can someone give some idea or document to setup RMAN backup for Oracle 11gR2 RAC.

There won't be any different settings for RMAN for RAC except for where and how you would be configuring the Archive logs and place your backups. Both, ideally speaking, should be on the shared storage like ASM but there are other combinations also possible. Review the above given links for the same. That should provide a good starting point.
