Using Oracle RAC VM tmeplates - Oracle Virtual Box

Greetings - can any one guide me to use Oracle RAC vm templates using Oracle Virtual Box?
Appreciated!

There is no need to burn a DVD because Virtualbox can directly mount and boot from the .iso image you downloaded. It is usually a good idea to check the md5 checksum of your download with the number provided by the download page to verify your download is not corrupted. There are no problems installing any version of Oracle Linux under Virtualbox provided you have the right hardware. I suggest to check the Virtualbox documentation.

Installing Oracle Linux 5.8 on Virtual Box

I'm trying to install Oracle Linux 5.8 on Virtual Box. I have downloaded V31120-01 and burned to the DVD, I think successfully.
However, when I start the Virtual machine, I get the Opening screen, "Oracle Linux" the little picture of the penguin guy, etc, so I think my DVD is good.
The screen says, "To install or upgrade in graphical mode, press the <enter> key." So I do.
Several lines of text flow across the screen, but then the process seems to stop with no prompt on what to do next or any indication that an error has occurred, it just stops.
The last lines I can see are:
ACPI: bus type pci registered
PCI: Using configuration type 1
ACPI: Interpreter enabled
ACPI: Using PIC for interrupt routing
ACPI: No dock devices found

I'm not sure if it's waiting for some input from me, or if there is a problem, but nothing happens beyond this point until I power down the virtual machine.

Can't install oracle 10g on windows XP(Virtual Box)

Hi all,
I have installed windows XP in Virtual Box, trying to install Oracle 10g in it. It won't start the installation..no clue about it. I installed winrar(as the 10g setup was in rar format, had to extract it).
without any issues winrar got installed, where as Oracle 10g simply wont get installed...no error message is thrown..
in fact I have installed 10g on a XP PC just last week..not sure where what I am missing
i am using "Briged Adapter" Network
If anybody has experienced same issue, kindly let me know....
mohib

Hi Srini,
Thanks for helping me with the link to be frank I had looked into it long back...
yes the software worked just yesterday, I had installed on XP(different machine).
I added my PC to domain, logged in as Administrator & double clicked, same....no response.
At last I used "command prompt" and it worked!! not sure how or why...but worked.
Now my database is created successfully
Yes would like to know why this happened....and how things worked via command prompt & not by double click....would greatly appreciate if anybody helps me on this.

Oracle RAC in my Home Linux Box.

Hi,
I have two Linux box at home loaded with RHEL 4, both have normal IDE HDD, is there any way, so that i can test ORACLE RAC on them, i just want to test RAC and get know about its working etc. please give me some idea about it, thanks

There's no need to have SCSI or RAID devices, although recommended for production. Follow simply the installation guide, besides there are some step-by-step documents here on OTN.

Oracle RAC with operating system virtual network cards

Hi,
I have two servers with four network cards each, two for public and two for private network. Each public card has own IP-address and the both have the virtual IP-address (from OS, not from Oracle Clusterware). Each private card has own IP-address and the both have the virtual IP-address. I have full redundancy for network cards. How should define Oracle Clusterware VIP-address for each machine?
Can somebody write me sample /etc/hosts file for this configuration?
Thanx,
Jacek

Very poor performance on oracle linux 6.3 on virtual-box 4.2

Dear all,
I installed an oracle linux 6.3 on vbox VM (2 gb RAM, 20 gb disk): the installation took a long time and after, I faced poor performance and big latency.
One bug reported:

I can confirm that there is no issue with Virtualbox 4.2 and Oracle Linux 6.3. I use it all the time. Performance should be near native and some aspects like disk I/O may even be faster. Your problem could be insufficient hardware, like missing x86_64 or hardware virtualization support. However, like rukbat wrote, this is not the right forum to discuss Virtualbox and your computer hardware here. I suggest to start with the Virtualbox documentation to verify your hardware is sufficient.

Oracle RAC FAN API - oracle.simplefan.*

Dear all,
has anyone got the FanListeners to submit event information by implementing the example in appendix b of the JDBC Developers guide? Except that the example has syntax errors and method names are wrong I couldn't get it to emit anything after fixing all the errors and running it. The API documentation draft is here: http://download.oracle.com/docs/cd/E11882_01/appdev.112/e13993/oracle/simplefan/package-summary.html. I am registering the Listeners with the subscription, yet regardless of what I do nothing gets written out on the console...
I am thankful for any pointers!
Martin

Hi,
1) check for any network-related issues, such as firewalls - they might be configured to block TCP connections between client and server
2) enable ALL logging for "oracle.simplefan"
And please post here your code and configuration file.

Oracle RAC on VMWare vs. Virtualbox

hello,
has anyone tested Oracle RAC DB 11g performance on VMWare server and on Virtualbox?
I wonder which virtual solution is faster.

I have created several Virtual Machines on my laptop using both VMWare Server 2 and Virtual Box (various versions utilized over time). I have found that the memory overhead of Virtual Box is lower then that of VMWare Server can not answer why I can jsut say that I have more free memory with Virtual Box then with VMWare Server 2 when using Virtual Machines with same configuration. On my Laptop I have not noticed a large performance difference between virtual box and VM Ware Server for Virtual Machines of like resource allocation and activity types, the performance appears to vary more by the resource consumption and activity executing within the VM. If I had to give a gut feel for an overall local VM tool, I like virtual box better then VMWare Server. I also see Virtual Box Updates coming, however not seen an update to VM Ware Server in a while. Hope this helps

Oracle RAC Interconnect, PowerVM VLANs, and the Limit of 20

Hello,
Our company has a requirement to build a multitude of Oracle RAC clusters on AIX using Power VM on 770s and 795 hardware.
We presently have 802.1q trunking configured on our Virtual I/O Servers, and have currently consumed 12 of 20 allowed VLANs for a virtual ethernet adapter. We have read the Oracle RAC FAQ on Oracle Metalink and it seems to otherwise discourage the use of sharing these interconnect VLANs between different clusters. This puts us in a scalability bind; IBM limits VLANs to 20 and Oracle says there is a one-to-one relationship between VLANs and subnets and RAC clusters. We must assume we have a fixed number of network interfaces available and that we absolutely have to leverage virtualized network hardware in order to build these environments. "add more network adapters to VIO" isn't an acceptable solution for us.
Does anyone know if Oracle can afford any flexibility which would allow us to host multiple Oracle RAC interconnects on the same 802.1q trunk VLAN? We will independently guarantee the bandwidth, latency, and redundancy requirements are met for proper Oracle RAC performance, however we don't want a design "flaw" to cause us supportability issues in the future.
We'd like it very much if we could have a bunch of two-node clusters all sharing the same private interconnect. For example:
Cluster 1, node 1: 192.168.16.2 / 255.255.255.0 / VLAN 16
Cluster 1, node 2: 192.168.16.3 / 255.255.255.0 / VLAN 16
Cluster 2, node 1: 192.168.16.4 / 255.255.255.0 / VLAN 16
Cluster 2, node 2: 192.168.16.5 / 255.255.255.0 / VLAN 16
Cluster 3, node 1: 192.168.16.6 / 255.255.255.0 / VLAN 16
Cluster 3, node 2: 192.168.16.7 / 255.255.255.0 / VLAN 16
Cluster 4, node 1: 192.168.16.8 / 255.255.255.0 / VLAN 16
Cluster 4, node 2: 192.168.16.9 / 255.255.255.0 / VLAN 16
etc.
Whereas the concern is that Oracle Corp will only support us if we do this:
Cluster 1, node 1: 192.168.16.2 / 255.255.255.0 / VLAN 16
Cluster 1, node 2: 192.168.16.3 / 255.255.255.0 / VLAN 16
Cluster 2, node 1: 192.168.17.2 / 255.255.255.0 / VLAN 17
Cluster 2, node 2: 192.168.17.3 / 255.255.255.0 / VLAN 17
Cluster 3, node 1: 192.168.18.2 / 255.255.255.0 / VLAN 18
Cluster 3, node 2: 192.168.18.3 / 255.255.255.0 / VLAN 18
Cluster 4, node 1: 192.168.19.2 / 255.255.255.0 / VLAN 19
Cluster 4, node 2: 192.168.19.3 / 255.255.255.0 / VLAN 19
Which eats one VLAN per RAC cluster.

Thank you for your answer!!
I think I roughly understand the argument behind a 2-node RAC and a 3-node or greater RAC. We, unfortunately, were provided with two physical pieces of hardware to virtualize to support production (and two more to support non-production) and as a result we really have no place to host a third RAC node without placing it within the same "failure domain" (I hate that term) as one of the other nodes.
My role is primarily as a system engineer, and, generally speaking, our main goals are eliminating single points of failure. We may be misusing 2-node RACs to eliminate single points of failure since it seems to violate the real intentions behind RAC, which is used more appropriately to scale wide to many nodes. Unfortunately, we've scaled out to only two nodes, and opted to scale these two nodes up, making them huge with many CPUs and lots of memory.
Other options, notably the active-passive failover cluster we have in HACMP or PowerHA on the AIX / IBM Power platform is unattractive as the standby node drives no resources yet must consume CPU and memory resources so that it is prepared for a failover of the primary node. We use HACMP / PowerHA with Oracle and it works nice, however Oracle RAC, even in a two-node configuration, drives load on both nodes unlike with an active-passive clustering technology.
All that aside, I am posing the question to both IBM, our Oracle DBAs (whom will ask Oracle Support). Typically the answers we get vary widely depending on the experience and skill level of the support personnel we get on both the Oracle and IBM sides... so on a suggestion from a colleague (Hi Kevin!) I posted here. I'm concerned that the answer from Oracle Support will unthinkingly be "you can't do that, my script says to tell you the absolute most rigid interpretation of the support document" while all the time the same document talks of the use of NFS and/or iSCSI storage eye roll
We have a massive deployment of Oracle EBS and honestly the interconnect doesn't even touch 100mbit speeds even though the configuration has been checked multiple times by Oracle and IBM and with the knowledge that Oracle EBS is supposed to heavily leverage RAC. I haven't met a single person who doesn't look at our environment and suggest jumbo frames. It's a joke at this point... comments like "OMG YOU DON'T HAVE JUMBO FRAMES" and/or "OMG YOU'RE NOT USING INFINIBAND WHATTA NOOB" are commonplace when new DBAs are hired. I maintain that the utilization numbers don't support this.
I can tell you that we have 8Gb fiber channel storage and 10Gb network connectivity. I would probably assume that there were a bottleneck in the storage infrastructure first. But alas, I digress.
Mainly I'm looking for a real-world answer to this question. Aside from violating every last recommendation and making oracle support folk gently weep at the suggestion, are there any issues with sharing interconnects between RAC environments that will prevent it's functionality and/or reduce it's stability?
We have rapid spanning tree configured, as far as I know, and our network folks have tuned the timers razor thin. We have Nexus 5k and Nexus 7k network infrastructure. The typical issues you'd fine with standard spanning tree really don't affect us because our network people are just that damn good.

what is the right Net Service name?
Thanks in Advance
lukx

Hi Oleg,
many thanks for the answer.
My doubt is on the right service name specificaton.
I create 2 service unique name for istance 1 (racistnt1) ed istance 2 (racistnt2)
I use srvctl command for create these.
In tnsnames must by use on node 1
(service_name = racsvr1)
(istance_name = racistnt1)
or
(service_name = racsvr) --> cluster service name
(istance_name = racistnt1)
In tnsnames must by use on node 2
(service_name = racsvr2)
(istance_name = racistnt2)
or
(service_name = racsvr) --> cluster service name
(istance_name = racistnt2)
Steps Install OWB.
1. instal OWB on node 1 --> OK
2. copy rtrepos.properties from node 1 to node 2 --> OK
3. sqlplus owbrep SQL>@start_service.sql -->OK (i test it without start service too)
4. lunch reposinst.sh on node 2 --> KO
the choose 'Registera Application Cluster (RAC) istance' don't appear

Oracle rac 11g installation

Hi
Am planning to install oracle RAC 11g on linux server. Have doubt on installation of clusterware or grid infrastructure first .?
I think grid infrastructure covers clusterware and ASM both and then oracle 11g software to be installed.
But how to download grid insfrastructure software. Will it come with oracle 11g software..? or need to download it seperately.?
Because when i try to download oracle RAC 11g which gives link to download the 11g software not grid.
Thanks in advance,

Hi,
Its called "oracle one node rac" you will find plenty of documents on metalink, extract is below, hope this helps you to understand the differences.
Oracle RAC Database : Oracle RAC database is a clustered database. It can have more than one instance running on one or more hosts. To make is database RAC , there is another software needs to be installed called Oracle Grid infrastructure which takes care of multinode sync, ASM, Oracle restart etc. Oracle GI is necessary as a base of Oracle RAC. In Oracle RAC, the load is balanced across multiple instance of databases running on different nodes. This is best for Production database. Failure of any instance is abstracted from user and forwarded to another instance from the database server pool. No of instances can be controlled using Policy Managed or Admin Managed.
Oracle RAC One Node : Some time we need to have RAC databases but donot need many instances, why? Simple answers to it is leverage the high availability of RAC. The Oracle RAC One node is a RAC DB runs on one host. The advantage is it saves your resource, can to converted to full RAC any time, Cluster fail over i.e. the Database instance is moved to new instance in case of any failure on host known as Instance Relocation,easy to upgrade etc. This type of database is well suited for small production and dev/test environments.

Oracle RAC requires ODP?

I am starting a new project with the following scenario: .Net 2.0 web application accessing Oracle RAC (64 bits) using Data Access Application Block. I would like to know if it is required to use ODP to access Oracle RAC or Microsoft Oracle Data Provider could be used. Another questions: Do ODP supports .Net 2.0? Is it possible to configure ODP in Data Access Application Block?
Any help is appreciated.
Luciana

Hi,
ODP.NET does not currently support ADO2.0. There should be a beta coming up sometime soon for it, and there are other threads you can check to get info to get in on the beta if you want to do that.
A lot of the RAC functionality is handled by the underlying client, so both ODP's should be able to take advantage of it, at least in some sense. However, as of 10.2, Oracle's ODP has additional functionality to be able to get notification when RAC events occur.
I dont know much about DAAP, but believe there are other threads where folks have converted it to Oracle code.
Hope that helps,
Greg
