Install vm on shared storage

Hi,
I am trying to install a virtual machine on a NetApp box.
I have created a storage repository with ovs-makerepo and if I do a "df -h" I can see the new storage is attached.
Now I would like to create a virtual machine by using vm manager and not the command line. I like to have it installed on this new repository however how is this done?
Regards,
Johan.

no, it will need to be installed on each of the machines. I'm
getting ready to roll out Air to a good chunk of computers here at
my office; we are starting out with a few hundred, but I think we
have over 6k devices in total.
Adobe has some great easy to follow instructions for setting
up Air via SMS.

Advantages of Shared Storage in SOA Cluster

HI,
Enterprise deployment guide ( http://download.oracle.com/docs/cd/E15523_01/core.1111/e12036/toc.htm) , installing binaries in shared storage.
We have NAS as shared storage.
My Question is what are the advantages/disadvantages of installing binaries in shared storage?
One advantage i know as mentioned in the guide is that, we can create multiple soa servers from single installation.
Thanks
Manish

It has always been my understanding that the shared storage is prerequsite, not a recommendation, meaning if you want a cluster configuration you must have shared storage. I have done a quick look through the EDG can't can see any reference installing binaries on a non-shared storage.
I'm not 100% on this but I don't believe the WLS and SOA home are used during run time. The run time files used are in the managed server location, e.g. user_projects. By default this sit in the WLS home.
Also don't know much about shared storage, e.g. NAS over SAN but if you already have NAS, this seems to be the logical choice.
cheers

How to change permissions on shared storage to install Oracle RAC on vmware

Hello:
- I am trying to install Oracle RAC using vmware.
- But when I try to change permissions for the shared storage,
the owner and group of the shared storage does not change.
- Has some else installed Oracle RAC onto vmware ?
- I am using Oracle RAC 10.2.0, solaris 5.10 x86

Problem of using OCFS2 as shared storage to install RAC 10g on VMware

Hi, all
I am installing a RAC 10g cluster with two linux nodes on VMware. I created a shared 5G disk for the two nodes as shared storage partition. By using OCFS2 tools, i formatted this shared storage partition and successfully auto mounted it on both nodes.
Before installing, i use the command "runcluvfy.sh stage -pre crsinst -n node1,node2" to determine the installation prerequisites. Everything is ok except an error "Could not find a suitable set of interfaces for VIPs.". By searching the web, i found this error could be safely ignored.
The OCFS2 works well on both nodes, i formatted the shared partition as ocfs2 file system and configure o2bc to auto start ocfs service. I mounted the shared disk on both nodes at /ocfs directory. By adding an entry into both nodes' /etc/fstab, this partition can be auto mounted at system boots. I could access files in shared partition on both nodes.
My problem is that, when installing clusterware, at the stage "Specify Oracle Cluster Registry", I enter "/ocfs/OCRFILE" for Specify OCR Location and "/ocfs/OCRFILE_Mirror" for Specify OCR Mirror Location. But got an error as following:
----- Error Message ----
The location /ocfs/OCRFILE, entered for the Oracle Cluster Registry(OCR) is not shared across all the nodes in the cluster. Specify a shared raw partition or cluster file system that is visible by the same name on all nodes of the cluster.
------ Error Message ---
I don't know why the OUI can't recognize /ocfs as shared partition. On both nodes, using command "mounted.ocfs2 -f", i can get the result:
Device FS Nodes
/dev/sdb1 ocfs2 node1, node2
What's the possible wrong? Any help is appreciated!
Addition information:
1) uname -r
2.6.9-42.0.0.0.1.EL
2) Permission of shared partition
$ls -ld /ocfs/
drwxrwxr-x 6 oracle dba 4096 Aug 3 18:22 /ocfs/

Hello
I am not sure how far this following solution is relevant to your problem (regardless when it was originally posted - may help someone who is reading this thread), here is what I faced and here is how I fixed it:
I was setting up RAC using VMWare. I prepared rac1 [installed OS, configured disks, users, etc] and the made a copy of it as rac2. So far so good. When, as per the guide I was following for RAC configuration, I started OCFS2 configuration, faced the following error on RAC2 when I tried to mount the /dev/adb1:
===================================================
[Root @ *rac2* ~] # mount - t ocfs2 - o datavolume, nointr / dev / sdb1 / ocfs
ocfs2_hb_ctl: OCFS2 DIRECTORY corrupted WHILE reading uuid ocfs2_hb_ctl: OCFS2 DIRECTORY corrupted WHILE reading uuid
mount.ocfs2: Error WHEN attempting TO run / sbin / ocfs2_hb_ctl: "Operation not permitted" mount.ocfs2: Error WHEN attempting TO run / sbin / ocfs2_hb_ctl: "Operation not permitted"
===================================================
After a lot of "googling around", I finally bumped into a page, the kind person who posted the solution said [in my words below and more detailed ]:
o shutdown both rac1 and rac2
o in VMWare, "edit virtual machine settings" for rac1
o remove the disk [make sure you drop the correct one]
o recreate it and select *"allocate all disk space now"* [with same name and in the same directory where it was before]
o start rac1 and login as *"root"* and *"fdisk /dev/sdb"* [or whichever is/was your disk where you r installing ocfs2]
Once done, repeat the steps for configuring OCFS2. I was successfully able to mount the disk on both machines.
All this problem was apparently caused by not choosing "allocate all disk space now" option while creating the disk to be used for OCFS2.
If you still have any questions or problem, email me at [email protected] and I'll try to get back to you at my earliest.
Good luck!

When installing clusterware, shared storage trouble

I was trying to install clusterware. When I typed location of OCR, I got error below:
Oracle Cluster Registry (OCR) is not shared across all the nodes in the cluster
Then, I found I can not mount ocfs2 on both nodes at the same time. But I can mount it on any one of nodes if it is umounted on the other one.
Can you anyone give me a hand?
Environment is as following:
- OS: Oracle Linux 5 (update 4)
- Openfiler 3 + ocfs2
- Oracle 10gR2

Is it possible to install Oracle RAC without shared storage

Dear All,
I would like to seek for your advice.
I got two different servers. We call it node 1 and node 2. And two different instances name.
Node 1 -> instance name as "ORCL1"
Node 2 -> instance name as "ORCL2"
For the system we need Oracle RAC active-active cluster mode. Our objective is to have 2 replicated databases, in other words we need 2 instances of the same database automatically replicated for 100% up time to the Application server. We have 2 separate database machines and 2 application server machines. We need our application server to connect to any of the databases at any point of time and be having a consistent data on both database machines. We only need the database to be in a cluster mode, we won't need the OS to be in a cluster. There is no shared storage in this case.
Can this be done? Please advice.

you should review RAC concepts, and the meaning of instance and database
For the system we need Oracle RAC active-active cluster mode.RAC = single database with multiple instances all accessing the same shared storage, no replication involved
Our objective is to have 2 replicated databases, in other words we need 2 instances of the same database automatically replicated for 100% up time to the Application server.what you describe here is = multiple databases with multiple instances, replicated between each other

We only need the database to be in a cluster mode, we won't need the OS to be in a cluster. There is no shared storage in this case.no shared storage = no RAC
you will have two seperate databases synchronizing continuously
you can use for example Streams / Advanced Replication (with multi-master configuration)
if you dont insist on an active-active configuration, you can also use Data Guard for building a standby database

Access iphoto 08 file on shared storage device from multiple machines

I recently installed ilife 08 on both an imac and macbook. Previously (iphoto 06), both devices accessed the iphoto library on a shared storage device without any problems. After the upgrade, my imac is able to view thelibrary but my macbook (the second machine to be upgraded) no longer has access. 'Sharing' is too slow over the wireless network and doesn't represent a reasonable option.
Is anyone else experiencing this issue? Any suggestions.

Actually, neither repairing permissions or changing them with Get Info worked for me. What did work for me was deleting the empty iPhoto Library in the user folder who couldn't access the shared library, and put an alias of the shared library in that user's Pictures folder. Everything then worked as it did prior to upgrading. Thanks.

Hi Suresh Kumar,
Oracle Application Server 10g Release 2, Patch Set 3 (10.1.2.3) is required to be fully certified on OEL 5.x or RHEL 5.x.
Oracle Application Server 10g Release 2 10.1.2.0.0 or 10.1.2.0.1 versions are not supported with Oracle Enterprise Linux (OEL) 5.0 or Red Hat Enterprise Linux (RHEL) 5.0. It is recommended that version 10.1.2.0.2 be obtained and installed.
Which implies Oracle AS 10.1.2.x is some what certified on RHEL 5.x
I think it would be better if you get in touch with Oracle Support regarding this .
Sorry , I am not aware of any document on migration from Sun Solaris to RH Linux 5.2 .
Thanks,

Qmaster error: shared storage client timed out while subscribing to...

Here's my Qmaster setup:
computer 1: CONTROLLER, no nodes
- 8TB RAID hooked up via Fiber
- connected to the GigE network switch via a 6-port bond
- cluster storage set to a path on the RAID
computers 2, 3, 4, 5: RENDER NODES
- each computer has a 2-port bonded connection with the GigE switch
computer 6: Client, with FCS2 installed.
- connected with a single GigE link
I have set up this cluster primarily for command-line renders, and it works great. I submit command-line renders from the client computer, which get distributed and executed on each node. The command line renders specify a source file on the RAID, and a destination path on the RAID. Everything works great.
I run into trouble when trying to use Compressor with this same setup. The files are on the RAID, and all my computers have an NFS automount that puts it in the /Volumes folder on each computer.
I set up my Compressor job and submit it to the cluster. It submits sucessfully, and distributes the work. After a few seconds, each node gives me a timeout error:
"Shared storage client timed out while subscribing to [computer1.local/path to cluster storage]"
Is this a bandwidth issue? Command line renders work fine, I can render 16 simultaneous Quicktimes to the RAID over NFS. I don't see much network activity on any of the computers when it's trying to start the Compressor render, it's as if it's not even trying to connect.
If I submit the SAME compressor job to a cluster with nodes ONLY on the controller computer, it renders fine. Clearly the networked nodes are having trouble connecting to the share for some reason.
Does anybody have any ideas? I have tried almost everything to get this to work. Hooking up each node locally to the RAID is NOT an option unfortunately.

WELL I DO NOW!
Thanks. it's taken 6th months and several paid 'professionals' and then you come in here...swinging your minimalist genius. one line. one single line. and its done.
if you are in london, lets lift a beer or five together.
thank you sir. thankyou!

How to implement RAC with no shared storage available...

Hello Guys,
I have installed, configured single node RAC R2 with 2 database instances on windows 2000 platform with the help of vmware software. Installation was successfull.
I just meet my boss to explain him my acheivements and to get permission to go for prodcution environment where we will be developing 3 nodes RAC on linux platform.
I asked him that we need a shared stroage system that can be achieved by SAN or NAS or firewire disks... but he refuses to buy any additioan hardware as we have already spend a lot on servers. He wants to me have another computer with a large size Hard Disk Drive to be used as shared storage.
I just want to know can we configure 3 nodes RAC using HDD of an other computer as sommon shared storage...
Please guide me. I really want to implement RAC in our production environment.
Regards,
Imran

Yeah, but would openfiler work? Has any one
implemented RAC using open filer or software
configured shared storage.
Any other better solution as i have to implement it
in production environment and have to seek better
backup facilities.Are you looking for a production environment, or an evaluation environment?
For an evaluation environment OpenFiler works. I occasionally teach RAC classes using that. It works but it is not as fast or as robust as I'd like in production.
For a production environment, plan to pay some money. The least expensive commercial shared stored I have found is from NetApp - any NetApp F8xx or FAS2xx files with iSCSI or even NFS license will do for RAC.

These are 3 things i am wondering how to handle, I did all these on Oracle Clusterware , but never on Veritas Cluster ware ...all these 3 steps are the same or different. In someone can help..

How we can do this while using varitas cluster software
1. Install oracle binaries and patches (RAC install)
2. Configure Cluster control interface (shared storage) for Oracle
3. Create instances of oracle
If we install RDBMS 10.2.0.1 with standard installer it will catch the vcs and when we will be running dbca it will ask for RAC db option?

Hi,
CLUFVY COMP SSA checks if the used storage/location is shared.
If you do "cluvfy comp ssa -t software" cluvfy checks if your software home is shared.
It tells you it is not. Hence the checks fails (which is correct, because you said DB Home is not shared).
So where is the problem?
CLUVFY COMP SSA only makes sense to check the sharedness. If it is not shared, then there is no sense in testing for it.

Sebastian

Do I have to have Shared Storage for Vm 3.0 ??

Hi
i used Oracle vm 2.2 .
where I can install vm by using Server's Storage .
Example
Server A has Vm 2.2 installed and it has 2Tb Storage .
From From Oracle Vm manager 2.2. I can create vm in Server A by using those 2Tb storage.
does this rules apply to Vm 3.0 ??
or for vm 3.0, you have to have Shared storage like Sun or something to hold vm's files ???
Please let me know ..
thanks

Does Hyper-v HA need shared storage?

I have a server running Hyper-v 2012 server. On this hyper-v host I have 1 DC and 1 DHCP server running. I don't worry too much in regards to fault tolerance with these servers. I have two other DCs running on physical servers and if DHCP goes down, it only
takes minutes to install DHCP elsewhere.
My company is now looking into virtualization and would like to start virtualizing more servers, servers that are critical and does need some type of HA and/or FT.
We are a SMB (~20 servers. mostly server 2008) company. For our most critical server, the longest it can stay down is 1 hour. So our recovery time should be less than 1 hour.
With all this said, what would you recommend in terms of building a virtual environment. Would using hyper-v replica be enough or would HA have to be implemented? If HA is implemented, and I imaging that the hyper-v hosts need to be in a cluster, would we
need shared storage (SAN) in order to use HA and/or FT?
Please let me know if you need more information.
Best regards,
Alex

I would recommend using a cluster setup for High Availability. Of course, that would require a shared storage. Ideally, you need to have a SAN for its performance. However, with Hyper-V 2012 and higher you can use SMB 3.0 for the shared storage instead.
More details here: https://technet.microsoft.com/en-us/library/jj134187.aspx
Of course, it remains better to have a replica too if this is possible.
