Oracle 11gR2 RAC - SCAN issue
We have Oracle 11gR2(11.2.0.1) RAC (2-node) on HP-UX. And we have some issue with SCAN Listener configuration.
Issue-1*
LISTENER_SCAN1 is running on node-1 and LISTENER_SCAN2 & LISTENER_SCAN3 is running on node-2. This is how it's running always. And we have 3 RAC database (cadprod, omsprod & eaiprod) running on this server. Both the instances of cadprod & eaiprod is registered on all three SCAN listeners.
But omsprod is having issues, omsprod1 & omsprod2 are registered on LISTENER_SCAN1 on node-1, but omsprod2 is not register on LISTENER_SCAN2 & LISTENER_SCAN3 on node-2. and some times we are not able to connect the second instance (omsprod2).
Issue-2*
And if node-1 goes down, all three databases are failover to node-2, after that we are not able to connect omsprod & eaiprid database its giving the following error on client side,
ORA-12516, TNS:listener could not find available handler with matching protocol stack
once the node-1 came back its allowing the connection. But cadprod doesn't have this issue, we are able to connect after the failover.

Oracle 11gR2 RAC Scan Virtual IPs
Hi, I have a doubt, I was installing Oracle RAC 11gR2 but I didn't understand how to do to resolve rac node ip address if the scan host has virtual ip and supposedly that ip address is not associated with specific host, when I attempt to ping to scan host why get response from rac nodes?
Thanks."..how to do to resolve rac node ip address if the scan host has virtual ip.."
use DNS to round robin the 3+ IP's.
"..and supposedly that ip address is not associated with specific host, when I attempt to ping to scan host why get response from rac nodes?"
it -is- associated with a specific host. but you did not assign that IP from the OS level, Oracle clusterware does that for you, dynamically.
In a two node RAC you will (assuming the recommended setup) have 3 SCAN listeners, so 2 on one node, and 1 on the other. If you stop the node with the 2 SCAN listeners, clusterware will reassign the corresponing IP's to the remaining node, and start the listeners there.
which you can obviously verify with ipconfig or netstat, or the /sys pseudo fs on Linux. -
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
ThanksDuring 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 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

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..
Thanks and Regards

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 ?

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 to RAC replication via SAN
Hi,
Anyone there experience before on Oracle 11gr2 RAC to RAC via EMC SRDF setup? Please share some information and also provide links if there is any white paper/technical paper.
Thanks
Edited by: 858013 on May 11, 2011 12:10 AMIn SAN replication, the database instance at the remote site cannot be started up and running as the SAN cannot allow read-write access to the filesystems.
When the primary site goes down, you simply issue a STARTUP at the remote site --- provided that the SAN replication has guaranteed write ordering, else you will have a corrupted database. That is why it is very important to talk to your SAN storage vendors to get the replication setup correctly.
(If the replication is correctly done, the STARTUP will "see" that the database files are fuzzy and that the onlin redo log files are available and attempt an Instance Recovery -- as if the instance / server had crashed or suffered a shutdown abort).

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 - 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?)
ThanksPlease 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. -
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?
Thanks937054 wrote:
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:

FATAL: Module oracleoks not found
FATAL: Module oracleadvm not found
FATAL: Module oracleacfs not found

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) -

Thanks.Hi!
You can't resume runInstaller.
You must Clear you envinronment, and try again.
