Verify Oracle RAC installation tips

Our hardware team has done setup of oracle 10g RAC for 2 node on linux RHEL 4 OS.For clusterware they have used OCFS release 2 and for RAC database storage they have used ASM .Can you please guide me how to verify that Installation of RAC has done successfully and how to create database on that.

If I understand it right, you already have CRS and ASM running and want to make sure that everything required to create a database is available. If yes, you can run the cluster verification utility as indicated below:
cluvfy stage -pre dbinst -n <node1>,<node2>
Make sure your ASM instance is up and running on all the participating nodes, before you create a rac database....I don't think cluvfy can check the validity of ASM instance.

Oracle RAC installation failover

Hi,
I have an Oracle RAC installation with 2 nodes with the data stored on a shared OCFS partition. I had a client test the connection using jdbc string for RAC failover. I tried shutting down one of the nodes on the RAC installation and the client could not connect to the oracle cluster database for the next 5 to 10mins.
I understand that the client would failover to the next available listener (On the next retry connection) if the node it is currently listening to has failed. Is there any configuration i should make to increase the failover efficiency?
Thanks for any advice.

Hi,
Server side failover is arranged by setting the remote_listener parameter.
Client side failover is set by using T(ransparent) A(pplication) F(ailover) (9i and higher)
or F(ast)C(onnection)F(ailover). Both are documented in the Net administrators manual for the version you didn't care to mention.
As far as I know, both TAF and FCF are not supported by the JDBC thin driver.

Oracle RAC Installation

Dears ,
I am installing oracle RAC and ORACLE 11g with QFS or ASM on Solaris 10 , what is recommended to be installed first ?
1-Should I install oracle database first then oracle clusterware and ASM ? OR
2-Install Oracle Clusterware and ASM then oracle database?
Do i need a licence fot ASM or QFS to install them ?
Is there any precaustion or recommendation i should follow before installation ?
Thanks in advance

Do i need a licence fot ASM or QFS to install them ?For ASM , you dont need any license . You need license only for database edition and RAC.

Oracle RAC Installation: Unix nodes, Windows ASM

I have a question about configuring Oracle RAC. I have never done any RAC or ASM installation before. Might be a stupid question for some of you.
Is it possible to install Oracle RAC using following options?
2 node RAC using Sun Solaris
Shared Storage using ASM in Windows server
Any additional information that you can provide will be greatly appreciated.
Thanks in advance

Hi,
First of all, do you have a shared storage available to both unix server or you want to use the windows server as a shared storage ?
From the documentation
Single Instance and Clustered Environments:
Each database server that has database files managed by ASM needs to be running an ASM instance. A single ASM instance can service one or more single-instance databases on a stand-alone server. Each ASM disk group can be shared among all the databases on the server. In a clustered environment, each node runs an ASM instance, and the ASM instances communicate with each other on a peer-to-peer basis.
Which means that you need to have ASM instance on every server where you have a database instance.
In case you don't have a shared storage to the unix servers, you have two options - iSCSI or NFS. You can setup the windows machine as an iscsi server and both unix machines as an iscsi clients then you will have shared storage on both unix machines. The other option is to configure the window machine as NFS server and mount the NFS share on both unix machines. Then you can deploy the data files directly at the NFS shared (not supported) or create empty files using dd and use then as device files for ASM.
For more information on ASM over NFS you can read Tim Halls article:
http://www.oracle-base.com/articles/linux/UsingNFSWithASM.php

Verify Oracle BI Installation (SE or EE)

Hello *!
We`ve upgraded an existing Oracle BI installation from 11.1.1.5.0 to 11.1.1.6.0 and the customer now don`t want to pay, because he claims, we`ve migrated from Enterprise Edition to Standard Edition.
How can i now verify the installation and show him, that we don`t migrated to SE?
Thanks
Harald

Hi Harald,
Heh, funny claim. What do they base this statement on?!
Just a little clarification:
- "SE" = ["Standard Edition"|http://www.oracle.com/technetwork/middleware/bi-standard-edition/overview/standard-edition-091029.html] - basically if you really went from EE ot pure SE then you'd have noticed for sure.
- "SE One" = ["Standard Edition One"|http://www.oracle.com/technetwork/middleware/bi-foundation/standard-edition-one-095406.html] - The SE1 shares the same install binaries as the EE. The restrictions apply in terms of usage, not in terms of installed programs.
- "EE" = ["Enterprise Edition"|http://www.oracle.com/technetwork/middleware/bi-enterprise-edition/overview/index.html] - the real deal.
So basically ask them: "what makes you say this?!"

Help requested on FireWire (SBP2) on CentOS 4.5 for Oracle RAC installation

I am running 64-bit CentOS 4.5 (2.6.9-55.EL kernel) on AMD64. I can load the FireWire modules (SBP2, OHCI1394 & IEEE1394) and see the partitions created of the FireWire drive using fdisk -l. The /proc/scsi/scsi correctly shows the drive.
If I create an EXT2 or EXT3 on a partition, it's great. I can read/write on that without any problem. But when I try to perfom the following:
dd if=/dev/zero of=/dev/raw/raw1 bs=8196 count=12000 or any dd on any partition on that drive, I am getting:
ieee1394: sbp2: aborting sbp2 command
scsi4: destination target 0, lun 0
command: Read (10) and then bunches of numbers
ieee1394: sbp2: hpsb_node_write_failed
ieee1394: sbp2: Bus reset in progress -- rejecting command
But the dd finishes and I can see the partitions using fdisk -l
I have the following in the /etc/modprobe.conf file (also tried without serialize_io):
options sbp2 serialize_io=1 exclusive_login=0
Eventually, this problem is stopping me from implementing CRS & Oracle RAC.
Can somebody please tell me what's going on & how I can avoid these errors?
Thanks for your help.

Hi,
Did you compile the source code which downloaded from Oracle official website:http://oss.oracle.com/projects/firewire/files/source/oracle-firewire-modules-1286.tar.gz ?
Please check the following modules whether it have been loaded on the box.
1,ieee1394.ko
2,ohci1394.ko
3,raw1394.ko
Use "dmesg" to check if the disk connected to the firewire interface has been detected.
Regards

Hi,
I also want to know what kind of monitoring scripts I can use to setup as cron jobs to monitor or detect any failure or problems?
To monitor Cluster (OS Level):
I suggest you use a powerful tool "CHM" that already comes with product Grid Infrastructure.
What do you do to configure? Nothing ... Just use.
Cluster Health Monitor (CHM) FAQ [ID 1328466.1]
See this example:
http://levipereira.wordpress.com/2011/07/19/monitoring-the-cluster-in-real-time-with-chm-cluster-health-monitor/
To monitor Database:
PERFORMANCE TUNING USING ADVISORS AND MANAGEABILITY FEATURES: AWR, ASH, and ADDM and Sql Tuning Advisor. [ID 276103.1]
The purpose of this article is to illustrate how to use the new 10g manageability features to diagnose
and resolve performance problems in the Oracle Database.
Oracle10g has powerful tools to help the DBA identify and resolve performance issues
without the hassle of analyzing complex statistical data and extensive reports.
Hope this help,

Oracle RAC Installation on personal computer using VMWare

Please can you tell me the steps to Install Oracle 10g RAC using VMware in my personal computer which is a dual core processor and no Hardware RAID avaialable?

Hi,
It is many steps...
Windows
http://www.oracle-base.com/articles/10g/OracleDB10gR2RACInstallationOnWindows2003UsingVMware.php
Linux
http://www.oracle-base.com/articles/10g/OracleDB10gR2RACInstallationOnCentos4UsingVMware.php
That is basic installation in production is different eg.
put CRS_HOME in place where root is owner of parent directory, apply patchset after every component eg. install crs and then patch crs, instal asm then patch asm ....
you have to patch crs because of UNKNOWN statuses

Oracle 11gR2 RAC installation with DNS

Dear Guru's,
I want to configure RAC on two node cluster with DNS(For SCAN) in my testing server.
O.S: RHEL5.4(64 bit)
Oracle Version: 11gR2(11.2.0.2)
Note: Am creating nodes in VMware ESXi server.
Just I want to know whether DNS should be configure in any one of those NODES or in separate machine.
Bala :)

Hi Bala,
I want to configure my Database with & without DNS. (Will try both installation in different servers)I think, you have already received a link on very good article about Oracle RAC installation without DNS and DHCP (I mean Jeffrey Hunter's article).
There is one more about Oracle RAC installation with DNS and DHCP (http://gjilevski.com/2011/10/05/build-two-node-oracle-rac-11gr2-11-2-0-3-with-gns-dns-dhcp-and-haip/).
And want to know how it forwards the client connection if a node fails.. Can anyone update the URL for this..There are a lot of information about it:

SAP ECC6.0 installation with Oracle RAC

Hi Expert,
Current we working on SAP ECC6.0 installation with Oracle 10G RAC on AIX 5.3. The RAC are running on two nodes (servers). And we are using GPFS filesystem (not running on HACMP).
Overall we had completed the Oracle RAC installation (CRS+RDBMS) and tested the oracle failover and it work find. Now we want to start with the SAP installation (with HA). In the SAP installation documentation, it did request to create a virtual hostname on the node and execute the sapinst scripts with below command line.
#./sapinst SAPINST_USE_HOSTNAME=ascs00
But if we are running on Oracle RAC + GPFS do we need to specify the virtual hostname? If not, which hostname i should use to install the HA for SAP? Please advice.
Regards.

And then I'd continue with the documentation at:
SAP on Oracle => SAP on Oracle Real Application Clusters (RAC)
There you can find several installation guides for windows/UNIX/Linux

Oracle RAC multiple LISTENERS

Greetings,
I have 2 test databases on single Oracle RAC installation.
Is it possible to configure separate LISTENERS for databases?
Oracle v. 11.2.0.3
OS RHEL 6.3

Hi Farid,
Yes it is possible: You can create listener (netca or manualy) and add listener to resource srvctl .
1) Create a new RAC listener using 'netca'
As the grid user invoke "netca" from the 11.2 GRID_HOME, the select "Cluster configuration" -> "Listener configuration" -> "Add", enter Listener name as required. For example: "LISTENER_MON".
On the next page, "Select Subnet", the 2nd subnet will appear in the drop down list.
For example:
$ ./netca
Oracle Net Services Configuration:
Oracle Net Configuration Assistant is launched from Grid Infrastructure home. Network configuration will be clusterwide.
Configuring Listener:LISTENER_MON
prodserver1...
prodserver2...
Listener configuration complete.
Oracle Net Listener Startup:
Listener started successfully.
Oracle Net Services configuration successful. The exit code is 0
2) Add listener
$ ./srvctl add listener -l LISTENER_MON -s -p 1523 -k 2
3) Verify the new RAC listener
$ lsnrctl status LISTENER_MON
Thank you

How to install Oracle RAC using 11gR2 on Win 7 32 bit from scratch?

Hiii,
I am a fresher and I have a win 7 system 32 bit with oracle 11gR2.
I want to install RAC using two or more servers but I dont know too much about it.
I tried to search on google but all they are giving information in pieces(for win 7) or about Linux(Please tell me why its all Linux everywhere not windows).
Please let me know if there any site where I can find step by step installation from scratch.
What are basic requirements(/software if needed).
Thank you.

Hi,
First of all forget about Windows!! Oracle is mainly designed for Linux systems. Oracle runs as real multi-process on Linux machines whereas on Windows it runs as a single process with multi-thread.
Memory usage - huge pages,single CPU run queue, dnfs, storage systems... etc. lots of concepts exists.
Besides Windows is one of the most poorly designed operating systems, you should use it only to watch cute kitten movies on youtube... Believe me, you wouldn't want to learn Oracle on Windows...
So, install virtualbox and then setup Oracle Enterprise Linux on it as a first step... By the way you have to deal with DNS server for release 11.X, RAC, you may start with 10g for now.
ORACLE-BASE has all the installation steps explained detailly, search for "oracle base rac install" on google.
I also explained on my blog, but it is a little bit advanced installation using ZFS storage simulator. DNS server installation is also explained: http://ilkertaysi.com/2013/11/11/oracle-rac-installation-with-zfs-storage/

Linux set up for Oracle RAC (real application cluster)

Hi Guys,
I m wrkig as Oracle DBA.
Very curious to know the initials for RAC set up at OS level.
Can anyone provide his/her usefull guidelines for the same.
Although I know all steps at OS level also, but didn't did the set up of before Oracle RAC installation.
Want to increase knowlegde on like:
--how we sahre storage.
--how we set up network (private & virtual IP) and how can check working of NIC's.
--and other required things.
Will appreciate ur help and if someone want to share his/her personal experience.
Thx in advance.

Want to increase knowlegde on like:Here are very basic answers to very complex questions - from a pure Linux perspective running an Open Source stack and untainted kernel.
--how we sahre storage.Using multipath - this should ship with most 2.6 kernels. The kernel sees the shared storage LUNs as scsi devices - multipath does the rest. (and ASM can directly use a multipath device).
On a physical layer. Typical setup (on a RAC node) is using a HBA PCI card that runs fibre connections into a SAN switch. You can also use Infiniband (IB) as the I/O layer (as Oracle's Exadata database machine does). In this case the servers will use HCA PCI cards, run IB cables into the switch, and so will the storage array run an IB cable into the switch.
--how we set up network (private & virtual IP) and how can check working of NIC's.Depends on the achitecture choses as Interconnect. Typical choices are GigE or Infiniband (IB). Oracle's Exadata database machine (RAC) uses IB as already mentioned. (and is also our preferred Interconnect technology)
With IB you would use the OFED driver stack and have a range of ib.. commands available. These can be used to configure IP over IB (IPoIB) for use as an IP-based Interconnect, bonding of NICs, check a port's status, and so on.
--and other required things.As both Daniel and Hans indicated.. you are asking quite complex questions that require a manual (if not several) to be written in response. So best to refer to the manuals and OTN material available.
Also, if you and your company are serious about using RAC, then you should make use of Oracle's RAC Assurance group to assist you. They will provide you with starter kit information for the o/s selected. They will check every single configuration parameter afterwards and deliver a comprehensive report on what's wrong, what works and what doesn't. With recommended changes that need to be done.
