SCAN Name issue in Oracle 11gR2 RAC Installation

Hi,
I am trying to install Oracle 11gR2 RAC on VM ware and I got the INS-40922 (Invalid SCAN name). Do I need to create the SCAN name prior to the installation?
I have public,private, and VIP's. I am not sure how I create this SCAN Name. Please share your thoughts
Thanks

During installation of grid infrastructure SCAN will be automatically created. If you are using DNS then put the scan name and scan ip addresses entries in DNS . If you are not using dns/gns then put scanname and scan ipadress hosts file on each node in the cluster. Before installation, you should not be able to ping scan ipadresses.

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 installation

Hi Gurus,
In new project we have proposed to have 2 nodes single site RAC database Oracle 11gR2 64 Bit . We are going to have OEL 5.4 64 Bit Linux as OS and IBM as machine .
We are migrating standalone 10g R2 database to 11r2 Rac and from HP-UX to OEL Linux . We are migrating from different datacenter .
What would be the pfile configuration (i mean memory size doubles ) in RAC ?
We are going to use IBM storage . Need light on followings . Pls help me out
1>Requirements for installation
2>Grid installation requirements
3>ASM instance is physical database instance or just service ?
4>Any oracle document for installation of 11gR2 Grid and RAC?
If you provide me authorized links of RAC installation that would be better .
Thanks & Regards

Oracle 11GR2 rac installation in vmware

Hi all experts,
I am installing RAC 11GR2 in VMWARE on OEL 6.3. Everything went smooth but when i tried to configure ASM , i get below messages.

Oracle 11gR2 RAC Installation - ASM Disks - Need advice on configurations

Hi Guys
How many disks are needed for Voting, Data, Log and Failover. Each should be in a seperate group or it can be in a single group of disk. Please advice. Thanks.

Hi Friend,
Option 1 :
If Oracle Clusterware is used for implementing normal redundancy. We require the following for failover purpose also.
1. Two OCR files - 280 MB each
2. Three Voting Disks - 280 MB each
Total - 1.4 GB approx
Option 2 :
Oracle recommends that the disk used for the file system be on a RAID. When you use external redundancy the minimum requirement is One OCR and One Voting Disk with 280 MB each.
Choices :
1. External Redundancy - > Minimum No Of Disks (1) - > One OCR (280 MB) and One Voting Disk (280 MB) -> 580 MB
2. Normal Redundancy - > Minimum No Of Disks (3) - > Two OCR (560 MB) and Three Voting Disk (840 MB) -> 1.4 GB
3. High Redundancy - > Minimum No Of Disks (5) - > Three OCR (840 MB) and Five Voting Disk (1.4 GB) -> 2.3 GB
So, Choose based on redundancy...
Hope it helps..
Note : Use ASM for storing above files..
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.

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:

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:

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

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..

Oracle 11gR2 RAC: how to solve "user profile creation mask failed" ?

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 am using Cluster Verification Utility (CVU) to test the 2 nodes for Grid installation as follows:
[ora11g@rac1 grid] $ ./runcluvfy.sh stage -pre crsinst -n all -r 11gR2 -orainv ora11g -fixup -fixupdir /mydir -verbose
All items for rac2 are passed. There is only one item for rac1 is not passed as follows:
Check default user profile creation mask:
Node Name: rac1
Available: 0002
Required: 0022
Comment: failed
There are 3 ways to solve this issue:
1) In the file /etc/bashrc, change the line "umask 0002" to "umask 0022".
2) In the file /etc/profile, add line "umask 0022" at the end of the file.
3) In the file /etc/csh.cshrc, change the line "umask 002" to "umask 0022".
In rac2, I got the same issue in the past. I just change the line "umask 0002" to "umask 0022" in the file /etc/bashrc and the issue is solved.
But in rac1, I have tried each of the 3 options and also combined 1) and 2), 1) and 3), 2) and 3), 1) and 2) and 3). Totally, that's 7 options. But all of 7 options cannot solve the issue.
The script runcluvfy.sh still tests rac1 user profile creation mask failed. My question is:
Do any folk understand how to solve VM rac1 user profile creation mask problem ?
Thanks.

Folks,
Hello. I follow the document "Oracle Grid Infrastructure Installation Guide 11g Release 2 (11.2) for Linux E22489-04" and do the following:
[root@rac1 /]#echo $SHELL
Output: /bin/bash
This means we need to edit Bash shell file .bash_profile.
[ora11g@rac1 ~]$vi /home/ora11g/.bash_profile
Add this line: umask 022
Then I save the file .bash_profile and reboot OS.
Then I run the following command:
[ora11g@rac1 grid] $ ./runcluvfy.sh stage -pre crsinst -n all -r 11gR2 -orainv ora11g -fixup -fixupdir /mydir -verbose
But the reusult is the same. The issue is not solved as follows:
Check default user profile creation mask:
Node Name: rac1
Available: 0002
Required: 0022
Comment: failed
Do any folk understand how to solve VM rac1 user profile creation mask problem ?

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.

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.

Oracle 11gR2 RAC - R language integration

Hello,
We want statistical language R integration with oracle database. Does this come with default installation of oracle database Oracle 11gR2 RAC ?
OR it requires EXADATA - BIGDATA (oracle appliance)?
Kindly let us know steps for installation /enabling R language ? Basically we are looking for 3 options (transparency, In-database, embedded). Optimal option choice is done automatically depending on R language script (I think R script needs to have different calls?)
Thanks

Please do NOT duplicate your questions here.
R is a language. Oracle is a database. You store data in a database. You write programs [using a language such as R] to extract and manipulate data from the database.

Oracle 11gR2 RAC - timeseries

Hello,
We would like to know if Oracle 11gR2 RAC supports timeseries data storage and time-series functions. Timeseries storage is quite different - in terms of storage optimization - block storages, compressions, columnar databases and others. Time-series functions like regressions, data-mining. Does these options come by default or we require statistical language R integration?
Thanks

Hello,
1. Usally time-series data goes in multiple millions, so timeseries databases like FAME,KDB,SYBASE-IQ are used. Does oracle11gr2 provide storage optmizations, compressions, columnar database like FAME,KDB,SYBASE-IQ?
The only methods of optimization are partitioning of the data by some date or if data set is narrow (few columns)l enough, partitioned IOT.
2. http://www.oracle.com/us/corporate/press/1515738
Link is about R statistical language and data mining integration with Oracle database 11gR2. Does this come default during installation or with BigData - EXADATA? OR this is a seperate license?I am not sure about the licensing, you will need to ask your sales person, but it looks like it might be apart of ODM (oracle data mining - a licensed product)
Take a read through this case study.

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:
CRS-4123: ohasd is starting
FATAL: Module oracleoks not found
FATAL: Module oracleadvm not found
FATAL: Module oracleacfs not found
ACFS-9121: Failed to detect /dev/asm/.asm_ctl_spec
ACFS-9310: ADVM/ACFS installation failed.
ACFS-9311: not all components were detected after installation
'UpdateNodeList' was successful.
[root@rac1 /]#
[root@rac2 /]# /u01/app/grid/root.sh
Output:
CRS-4123: ohasd is starting
FATAL: Module oracleoks not found
FATAL: Module oracleadvm not found
FATAL: Module oracleacfs not found
ACFS-9121: Failed to detect /dev/asm/.asm_ctl_spec
ACFS-9310: ADVM/ACFS installation failed.
ACFS-9311: not all components were detected after installation
Start of resource "ora.asm_init" failed.
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)
