RAC Implementation in Oracle 11g

How to implement RAC in oracle 11gR2? is there any documentaion or links to get more info on Oracle RAC

Other than the scant thousands of pages available through http://docs.oracle.com ?
You could also go to http://otn.oracle.com and
1) Docs and white papers:
- click on Database (under Products, left edge) to get to the Database information
- then click on High Availability
- then click on Real Application CLusters and look at the various whote papers and supplement info
2) Example install articles
- click on Articles (top menu)
- search for DBA / RAC articles by people like Jeff Hunter
Alternately, GIYF / LMGTFY

ASM Installation on Oracle 11g Clusterware (RAC) environment

Hi All,
I am trying to setup Oracle 11g Standared Edition RAC+ASM on RedHat Linux 5.0 VM ware box. As part of this RAC setup successfully completed. For this i have used raw devices and mounted using NFS.
In many of forumns i have read that ASM installtion on a cluster envioronmnet is different than non cluster environment.
I dont know how to start ASM installtion on RAC environment. Please share any documents if you have?
Thanks,
Rakesh

will the steps need to be done on two nodes of cluster or it is sufficient on first node.
"raw device" for OCR, VOTE, SPFILE_FOR ASM and ASM DISKGROUPs
before do "raw devices" you have to fdisk(make partitions) on share storages
node1:
# fdisk /dev/sdf
# ls /dev/sdf*
node2:
# ls /dev/sdf*
don't find...,so just fdisk -> l and -> w
fdisk how? http://linux.about.com/od/commands/l/blcmdl8_fdisk.htm
Example: /etc/sysconfig/rawdevices do it every nodes
#Oracle OCR File +~280M+
/dev/raw/raw1 /dev/sdf1
#Oracle Voting File +~280M+
/dev/raw/raw2 /dev/sdf2
#Oracle ASM spfile ~50M+
/dev/raw/raw3 /dev/sdf3
#Oracle ASM DISK Group1
/dev/raw/raw4 /dev/sdg1
#Oracle ASM DISK Group2
/dev/raw/raw5 /dev/sdh1
And oracle user.. can read /dev/raw/raw* You should find on every nodes
http://oraclepitstop.wordpress.com/2008/02/15/raw-devices-on-rhel-5-or-oel-5/
ls -la /dev/raw/raw*
crw-rw---- 1 root oinstall 162, 1 Jan 13 12:53 /dev/raw/raw1
crw-rw---- 1 oracle oinstall 162, 2 Jan 13 12:53 /dev/raw/raw2
crw-rw---- 1 oracle oinstall 162, 3 Jan 13 12:53 /dev/raw/raw3
crw-rw---- 1 oracle oinstall 163, 1 Jan 13 12:53 /dev/raw/raw4
crw-rw---- 1 oracle oinstall 164, 1 Jan 13 12:53 /dev/raw/raw5
do it on node1 but you have to pass phrase on every nodes Before
http://www.puddingonline.com/~dave/publications/SSH-with-Keys-HOWTO/document/html/SSH-with-Keys-HOWTO-5.html
example:
node01:
$ ssh node01 hostname
node01
$ ssh node02 hostname
node02
- Install + Setup Clusterware:
OCR = /dev/raw/raw1
VOTE = /dev/raw/raw2
- Install Oracle Database for ASM Home
spfile for ASM = /dev/raw/raw3
- after ASM started... create disk groups from /dev/raw/raw4 and /dev/raw/raw5
- Install Oracle Database for RDBMS Home
- Create Database to use ASM diskgroups
http://www.oracle-base.com/articles/11g/OracleDB11gR1RACInstallationOnRHEL5UsingVMwareESXAndNFS.php
Did you followed the same procedure to set up Oracle 11g RAC+ASM on RHEL 5.0.I'd done(test 11gRAC) it on RHEL 4 + 11g + ASM(on raw device)
on production, I use ASMlib... + ASM + 10g

ThanksHi,
Active dataguard is option after configuring dataguard.
You can put standby database in Open(read only) mode also you can enable Recover(MRP) while open so this can be used for reporting purpose too.
Please refer below links for configuring them.

How to Create Manual Standby for a Oracle 11g RAC with ASM to Single Instan

Hi All,
I have a task to configure a Single Instance Standby Database with ASM for 2-node Primary RAC+ASM database.
Version using : 11.1.0.6 Oracle 11g --- *" STANDARD EDITION "* Please note datagaurd will not be supported in standard edition.
Primary database - 2 -Node RAC using ASM storage (All datafiles, redologs, controfile and archive logs)
Need to setup a single instance standby database manually and than using scripts to transfer the archive logs from primary server to standby server to do recovery time to time.
Please let me know if there are any configuration document(s) which can help me to set the manual standby? or need your kind help to give your valuable ideas how to go in above situation.
Thanks in advance

Well if the archive logs are stored in ASM on the primary nodes, you almost definitely want to be using RMAN to access them. Then to transfer between primary and standby there are many options, this is essentially the step that Data Guard takes care of - so if you (and I) are running Standard Edition, this is the part to "worry" about.
I'm not really sure what you mean by this:
As in standard edition the archive destination will be on ASMI don't think the Edition of Oracle (Standard or Enterprise) dictates where and how you store your archive logs, but it's possible I've misunderstood what you mean...SE dictates that database storage for RAC will be ASM, including archive log files. Anything else is not officially supported. I haven't tested but it may be that you can use LOG_ARCHIVE_DUPLEX_DEST to specify a local filesystem for archive log files as well.
If that doesn't work you'll have to script rman "backup as copy" jobs regularly and then transport the results of that.

By the way, it seems Robert has been pretty helpful, it's polite to give him some points dude. And since this is your thread, not mine, give him a "helpful" from me too :p
El DBA
Incidentally if you are forced down the RMAN backup as copy route then this will likely throw your current backup retention strategy somewhat, you'll need to think carefully about when an archivelog can be deleted following backup, how many times it might be backed up and so on. I do understand, and have argued for, the use of SE RAC. I also understand and have argued for and implemented manually managed standby a number of times. However by the time your primary database is a RAC instance and you need a standby for DR etc then you really have to look very seriously at whether Standard Edition is still the right investment or not. You will be spending a lot of DBA time managing and troubleshooting this, and you will find that it is less reliable than the off the shelf solution. I suspect that you are very close to the point where an EE installation becomes a worthwhile investment here.

Oracle 11g RAC on Windows 2008 R2 VMware EXS 3.5 virtual machines

Hi,
We are planning to Install Oracle 11g R2 RAC on two VMware EXS 3.5 Windows 2008 R2 servers.
Having trouble while assigning the storage to the servers, the Raw Device Mapping feature in the VMware is greyed out and we cannot assign the disks to the Virtual servers, the disks are allocated to the Vmware Host machine from the SAN (HP EVA).
Please guide me the best approach for the RAC configuration on VMware EXS 3.5 Win 2008 R2 Guest servers.
any help will be highly appreceiated.
Thanks.

Hi,
Is this implementation to production environment?
Be aware:
Is Oracle RAC on VMware supported? No, we do not support Oracle Software including Oracle RAC on VMWare.
Aside from the support restrictions for the database on VMWare outlined in Metalink Note 249212.1, there are technical restrictions that prevent the certification of Oracle RAC in a VMWare environment.
*RAC: Frequently Asked Questions [ID 220970.1]*
Having trouble while assigning the storage to the servers, the Raw Device Mapping feature in the VMware is greyed out and we cannot assign the disks to the Virtual servers, the disks are allocated to the Vmware Host machine from the SAN (HP EVA).Check if below can help you.

Can installing Oracle 11g on a client in the same network as another implementation cause problems?

Hi, I have a running Oracle 11g r2 installation running. Same network, different subnet. I want to install 11gR2 for development/testing on another machine not connected in any way to the other system other than they are on the same network (different subnet).
Is there anything that happens over the network that can screw something up? I do not want to interfere with my existing implementation in production.

Multiple installations of Oracle don't react like multiple ex-wives at a will reading
However if you need to access both production and development instances from the same client you probably want to have a different names for each instance e.g. XXXDEV vs. XXXPRD to easily check which instance you are connecting to.

I tried reinstalling again and it worked on Vmware Server.Some oracle products are certified on Oracle VM , but not RAC at the moment.
You can download Oracle VM from otn.oracle.com

Oracle 11g RAC on CentOS 5.2 - Node isnt working after hardware failure

Hi,
We have a 2-node Oracle RAC 11g running on identical nodes with Centos 5.2 as operating system.
Due to a drive failure and a reboot yesterday, the ASM disk, which is onnected via iSCSI, changed from sdd to sdc in name - (the faulty raid drive was removed, thus the change).
The oracle services didnt start, which appeard perfectly logical at the time, given that the ASM disk suddenly wasnt where it was supposed to be, but even today after a replacement disk was inserted, the RAID rebuilt + with the ASM disk back to its original naming in /dev/; the node doesnt seem to work properly. Some of the oracle services are running, but there seems to be a problem with the listener, which might also explain why the node does not set it's virtual ip after starting up.
Luckily, the other one is unaffected and is working perfectly fine..
I'm far from having a clue about oracle, it was sheer luck (that, and the very usable documentation by oracle) that i managed to get that cluster running in the first place... I know my way around linux, so if it's a operating system related problem i'll be able to fix it, but i cant figure out what the problem with oracle is.
The listener doesnt seem to be running

Hi,
As usual, as soon as i post a problem in some board, i find the solution myself.
Although this way isnt really "linuxy", deleting the listener with the netCA tool and adding a new one solved it.

Oracle 10g RAC implementation running out of space

I have an Oracle RAC implementation setup on a Sun Storagetek 6140 for storage. I have allocated 100gb of space to Oracle but am constantly running out of space during operations. I know that i can allocate additional disk space using Common Array Manager for the Storagetek. How do i get ASM to recognize the fact that there is additional space available to it?

Hi buddy,
How do i get ASM to recognize the fact that there is additional space available to it?You have two options:
1- The first one is create a new LUN, configure it at the OS level and add the disk to disk group.
alter diskgroup add disk '<DISK_DEVICE_PATH>';
2- The second one is increasing the LUN size (if possible, of course) and resize the disk.
alter diskgroup <DISK_GROUP_NAME> resize disk '<DISK_NAME>' <NEW_SIZE>;
Hope it helps,
Cerreia

Thank you

Hi Everyone,
I installed Oracle RAC 11g on Windows 2008 64 bit, The installation was successfull crs_state -t executed successfully.
Bt the machine got crashed ,when executed a select query with 100 sessions( For performance evaluation using TG). A blue screen is appeared on two nodes. So i am not able to evaluate the performance.
Can you please tell any suggesstions to solve this issue? Is our hardware is not sufficient? Or any software settings has to be done?. I tried most of hte technique ,bt the problem still exists.
The following machine configuration is used for Oracle RAC setup
Intel Core 2 Duo 2.66 GHz,
Ram :4GB.
OS : windows 2008 Server 64 Bit
Oracle RAC , Clusterware 11g R2 64 Bit.

Oracle 11g R2 RAC on vmware

Hi All,
I have read many blogs and article about installing Oracle 11g R2 RAC on vmware. For self learning process what should be minimum configuration of hardware.
Minimum physical memory will be 8 GB what is minumum processor required ( 2 Cores / 4 Threads) or ( 4 Cores / 8 Threads)?
Native operating system will be Windows 7 64 bit.
Thx.

You wouldn't be doing much with the processors so it won' t matter hugely having a dual or quad core. As long as there is sufficient RAM(like 8gig) , you should be fine. Try to get SSD if you want more faster performance from the machine in terms of IO.
