Oracle 11gR2 RAC system Network Connection Problem among VMs

Folks,
Hello.
I am installing Oracle Database 11gR2 RAC system using 2 Virtual Machines (rac1 and rac2) on the top of VMPlayer 3.
I configure Network for rac1 and rac2 as following:
rac1 eth0 192.168.138.35 eth1 192.168.137.35
rac2 eth0 192.168.138.36 eth1 192.168.137.36
[root@rac2 \]# ping rac1
output: 64 bytes from rac1.localdomain (127.0.0.1) ... ...
[root@rac1 \]# ping rac2
Error: Ping rac2.localdomain... ... Destination Host Unreachable.
My questions are:
First, Why rac1 cannot reach rac2 while rac2 can reach rac1 ?
Second, How to have rac1 reach rac2 ?

Folks,
Hello. Thanks a lot for replying.
The public IP for eth0 and private IP for eth1 in the file "/etc/hosts" are as follows:
rac1 eth0 192.168.138.35 eth1 192.168.137.35
rac2 eth0 192.168.138.36 eth1 192.168.137.36
In rac1, I have added 2 entries in /etc/hosts as following:
#VIP for eth0
192.168.138.130 rac1-vip.localdomain rac1-genetic-vip
192.168.138.131 rac2-vip.localdomain rac2-cellar-vip
Then I execute the command: [root@rac1 /]# ping rac2
Output:
PING rac2.localdomain (192.168.138.36) 56(84) bytes of data
From rac1.localdomain (192.168.138.35) icmp_seq=1
Destination Host Unreachable
In rac2, I try to add the above 2 entries in /etc/hosts. But cannot save it. The following error message comes up:
"E45: readonly option is set (add ! to override)".
My questions are:
First, do I need to add VIP in the file "/etc/hosts" for both rac1 and rac2 ?
Second, why rac1 still cannot reach rac2 after add VIP in /etc/hosts for rac1 ?
Third, why the file "/etc/hosts" in rac2 is read-only ? How to change it to be editable ?
Thanks.

Problem of Copying the Original VM to 2nd VM in Oracle 11gR2 RAC system

Folks,
Hello. I have been installing Oracle Database 11gR2 RAC system using 2 nodes that are 2 Virtual Machines (rac1 and rac2) on the top of VMPLayer 3.
I follow the tutorial http://appsdbaworkshop.blogspot.com/2011/10/11gr2-rac-on-linux-56-using-vmware.html to do.
The original Virtual Machine rac1 has run correctly. I configure rac1 network (eth0 and eth1) by opening VM rac1 and using command "[root@rac1\] #neat" as root user to invoke the network configuration.
For the second Virtual Machine rac2, I simply copy all files in "C:\VM\rac1" into "C:\VM\rac2". Then I have done the following:
1) In the directory "C:\VM\rac2", rename "rac1.vmx" to "rac2.vmx".
2) Change display name from "rac1" to "rac2" in the file "rac2.vmx".
The next thing to do for rac2 is to open the Virtual Machine rac2 and configure its network (eth0 and eth1) by using the command "[root@rac2\]#neat" as root user.
But by this step, I don't understand how to open the Virtual Machine rac2 so that can configure its network (eth0 and eth1).
Can any folk tell me how to open the VM rac2 to configure its network by this step ?
Thanks.

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:

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-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)

Is VMPlayer3 supported by Oracle DB 11gR2 RAC system ?

Folks,
Hello. I have been running Oracle regular ( a single instance) Database 11gR1 successfully with Oracle Linux 5.6 as Guest OS in VMPlayer3 and with Windows 7 as Host OS for a long time.
Now, I am installing Oracle Database 11gR2 RAC system (2 nodes) in the same environment that is with Oracle Linux 5.6 as Guest OS in VMPlayer3 and with Windows 7 as Host OS.
I have installed Clusterware for 2 nodes. But it seems that VMPlayer3 is not supported by Oracle DB 11gR2 RAC system.
Only VMware Server 2.0.2 is supported. When I install VMware Server2.0.2 in Windows 7, the error message comes up as follows:
"Setup has detected that VMPlayer is already installed on this machine. Please uninstall this product through the Control Panel and try again."
This means we cannot installed VMPlayer3 and VMware Server 2.0.2 in one OS Windows 7. I have installed many VMs in VMPlayer3 and cannot uninstalled VMPlayer3.
My questions are:
Can any folk make sure whehter VMPlayer3 is supported by Oracle DB 11gR2 RAC system or not ?
If not, how to solve the issue that VMPlayer3 and VMware Server 2.0.2 cannot be installed in one OS Windows 7 ?
Thanks.

Folks,
Hello. As I know, VMPlayer 3 supports Oracle Linux 5.6 as Guest OS and Windows 7 as Host OS.
But when I am installing Clusterware and running the script root.sh, the error message comes up as follows:
"ADVM/ACFS is not supported on Oracle Linux-release-5-6-6.0.1".
My questions are:
First, what is ADVM/ACFS about ?
Second, can any folk make sure whether Oracle DB 11gR2 RAC system is compatible to run in Oracle Linux-release-5-6-6.0.1 in VMPlayer 3 with Windows 7 as Host OS ?
Thanks.

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.

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.

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 on Linux

Can we install Oracle 11gR2 RAC on Linux using OCFS2 for both Oracle software and OCR.
Actually i am facing problems with Oracle software location which is on OCFS2
Please help me

Though it would be technically feasible, oracle recommends against sharing oracle binaries for RAC.
You would be better off installing oracle binaries on a local mount on all nodes rather than a shared file system.
Cheers.

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 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

rac-framework-rg rac1 No Online
rac2 No Online
asm-inst-rg rac1 No Online

rac2 Online Online - Mounted: FRA
asm-dg-crs rac1 Online Online - Mounted: CRS
rac2 Online Online - Mounted: CRS
asm-dg-data rac1 Online Online - Mounted: DATA
rac2 Online Online - Mounted: DATA
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

Oracle 11gR2 RAC and DR setup

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.
- Mano

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 ORACLE DATAGUARD is what you need; not RAC

ORACLE 11gR2 RAC on Fedora 14 unsing qemu

Is it possible to install ORACLE 11gR2 RAC on FEDORA 14 using Virtual machine based on qemu which is by default available with FEDORA 14.
Can someone have any hint. I know this is not supported by ORACLE Corporation, But for learning purpose this would be great help.

Hi,
Not sure about gemu but you can easily setup a system using virtualbox since this is for learning shouldn't make much difference how you set it up.
