Solaris cluster, Oracle10g RAC

I just want to understand, which one is more favorable, most popular combination used by sun customers for Oracle10g RAC.
1) Solaris cluster + VERITAS Storage Foundation
2) Solaris cluster + QFS

Please refer to http://docs.sun.com/app/docs/doc/820-2574/fmnyo?a=view for the supported options for Oracle RAC data storage. This is important because if you stray outside these you will not be on a jointly Sun/Oracle supported configuration.
Therefore, if you want to put Oracle RAC (tablespace) data files on a cluster file system, you must use shared QFS as that is the only supported option open to you. Furthermore, you can only run sQFS on top of SVM/Oban or h/w RAID - we do not support running it on VxVM/CVM.

Oracle10g RAC Cluster Interconnect issues

Hello Everybody,
Just a brief overview as to what i am currently doing. I have installed Oracle10g RAC database on a cluster of two Windows 2000 AS nodes.These two nodes are accessing an external SCSI hard disk.I have used Oracle cluster file system.
Currently i am facing some performance issues when it comes to balancing workload on both the nodes.(Single instance database load is faster than a parallel load using two database instances).
I feel the performance issues could be due to IPC using public Ethernet IP instead of private interconnect.
(During a parallel load large amount of packets of data are sent over the Public IP and not Private interconnect).
How can i be sure that the Private interconnect is used for transferring cluster traffic and not the Public IP? (Oracle mentions that for a Oracle10g RAC database, private IP should be used for heart beat as well as transferring cluster traffic).
Thanks in advance,
Regards,
Salil

At least crossover interconnect is completely unsupported.

Oracle RAC on solaris Cluster - advantages

Hi,
I wonder what are the advantages of installing Oracle Rac on solaris Cluster.
Oracle Rac is a cluster solution by itself and puting it to solaris Cluster will complicate a whole system a lot.
One advantage I know iis that solaris cluster will secure a voting disks but those could be also secure by using NFS.
Please give me your opinion if its worth in general to iinstall RAC 11g in solaris cluster 3.2.
How do you think, will Oracle extend the solaris cluster solution for databases in the future ?
Many thanks in advance.

CRS is built to manage RAC. Using any other cluster software for RAC will complicate the solution without adding benefit.
But if you are building a cluster to run application servers etc, then it would be better to use a more flexible cluster solution. (e.g NOT crs)

Oracle10g RAC with Oracle clusterware

Hi,
We are installing Oracle10g RAC with Oracle clusterware with ASM on Solaris 10. Does anybody have a installation/configuration manual for this combination.
Thanks,
Murtuja

Sun would not recommend using Oracle 10g RAC without Sun Cluster. Setup for that configuration would be found in the Sun Cluster Data Service for Oracle 10g RAC and the Oracle installation manuals.
The installation of Oracle Clusterware alone would be documented in Oracle's manuals. If you have any problems with that, you are better off asking Oracle.

Oracle ASM Configuration on Solaris Cluster - Oracle 11.2.0.3

Hi,
I want some clarifications!
I need to set Active and Passive Cluster settup on Solaris 10 SPARC Operating System, the HA software is Solaris Cluster and Oracle 11.2.0.3.
1) I understand "Single instance Oracle ASM is not supported with Oracle 11g release 2" so we need to go for Clustered ASM - is it required to use RAC framework in this case?
2) When i use the RAC framework, do i need to have license for RAC?
Am new to Oracle, any help is appreciated.

Solaris Cluster 3.2 with Oracle 11i R2 oracle agent installation question

Hi all!
I'm new in clustering and trying to build a two-node cluster in my lab. At the moment i've successfully installed cluster software and oracle on the nodes and now i'm trying to integrate cluster with oracle DB. Unfortunately, i couldn't find the documentation about this task. Can anyone give me an URL, where to look? By the way: i tried to find something here: http://docs.sun.com/app/docs/doc/820-7360/fxjbo?a=view but found info only about Oracle RAC and nothing else, but i'm trying to build cluster without RAC - just only with solaris cluster.

Hi,
You might run into trouble with 11gR2 right now. You need to wait until the nxt patch for th eHA Oracle agent is avialble, or use 11gR1 at the moment.
Sorry for the bad news.

From what I have read Sun Cluster 3.2 will not be supported with RAC 11g R2 untill September time frame.
The functionality will be released via a cluster core patch.
Currently Sun Cluster is looking down in /etc/init.d/init.crs to start CRS (11g R1). With 11g R2 the start script for GRID is now /etc/init.d/ohasd.
SC does support HA 11g R2, but not RAC at this point in time.

Why we need CRS in Oracle10g RAC

When i am having third party cluster solution like Veritas(SFRAC for Oracle), why its not possible to configure Oracle10g RAC with Veritas without CRS ?????
Its possible in Oracle9i but why not in Oracle10g ????

because ASM is there !!!
in 10g you do not have to use raw devices to store data files : you just use the ASM instance which comes free and provides the performance of the raw devices with the management capabilities of any filesystem
you only need to configure raw devices for the OCR and Voting Disk (but this is really simple !!! compared to the management problem of storing datafiles on raw (no autoextend , mapping and so on)

Oracle10g RAC vs Oracle9i RAC with WebLogic

Hello, I am planning on installing Oracle RAC on Redhat's Linux AS 3.0, while BEA's WebLogic will the application server.
What would you choose as the back end, Oracle9i RAC or Oracle10g RAC and why ?
Also, what release/patch-level (sp ??) of Linux A.S should be used ?
EMC's storage disk arrays sould be used. Is anyone aware of any I/O issues between Linux AS and EMC disks ?
Thank you for your thoughts.

Tom

Solaris Cluster 3 nodes

Dears
I have 3 nodes solaris cluster running with Oracle 9i database , my plan to upgrade to to Oracle RAC 11g.
I have shutdown one node but i did not remove it from solaris cluster, i have installed Oracle 11g on it and will add second node.
My question is : If I remove the second node from suncluster , Is the cluster will work with only one node??
In the other meaning , I will remove 2 nodes out of 3 nodes cluser , is it possible?
Thanks
Ehab

I have 3 nodes cluser and 1 x storage 6580,
i created two quorom devices from the storage.
I will remove two nodes, Is cluster will still work on single node ?
Thanks

Solaris Cluster Server Homogeneous System Copy

Hi,
We have SAP ECC 6.0 on Solaris Sparc server. Our database is Oracle 10.2.0.2. We will buy 2 new solaris server and we want to use these server as cluster. We want to make homogeneous system copy from current server to new cluster server. How can we make homogeneous copy from current server to new cluster server? Firts of all do we have to install new ECC 6.0 on cluster server and then will we make homogeneous system copy?
Also how can we install ECC 6.0 on Solaris Cluster server? Will we have install ECC 6.0 seperatly for each server of cluster unit? I have SAP installation document but it is not clear. Do you have another document for SAP installation on cluster server? Please help us about these issues.
Best regards.

First to move your ECC system from your current server to the new server, yes you do need to homogenous copy. There are other methods like storage sub-system level copy, but it is not supported. Since your system is ABAP, you can setup standby database on the new server and use dataguard to replicate database. You can manual move profiles, binaries and other application file systems manually since they are on external storage. You should change your profiles to use logical hostname instead of the physical hostname though Solaris 10 gives you the ability to move zone/containers with same hostname.
I am assuming you have distributed system, ie database and SAP separate. You can setup RAC for database HA. For SAP, you can use sun cluster or veritas cluster to move SAP central instance with the logical hostname to the 2nd standby server.
You can also separate ASCS from SAP central instance and setup failover for the CS instance with the cluster software. Check notes 821904, 870652. You can take another step in HA with ENQ replication (see http://help.sap.com/saphelp_nw70/helpdata/EN/36/67973c3f5aff39e10000000a114084/content.htm)

Benchmark of Oracle10g RAC

Hi,
Does anyone know where I can find the benchmark of Oracle10g RAC (2 nodes or more ) on Sun Solaris?
Thanks

You may find this posting helpful for using free benchmark tool for oracle.
http://www.oraclepoint.com/topic.php?filename=166&extra=page%3D1 (register and then log in because it's only available for members.)
There are step-by-step installation guide and sample report of TPC-C.
Hope it helps.

Oracle10g RAC

Hi,
Can anyone help me,
Is there any problem for Oracle10g RAC running on Sun Solaris 10 using the latest SUN Containers feature?
regards,
Dilip.

Have a look at the Certify & Availability in Metalink for your Platform. Also the RAC Readme and documentation for Sun Solaris 10 will indicate if there are any known problems.
If in doubt and you are having any specific problems, I would suggest you open a TAR with Oracle Support.

Hi,
solaris has several issues with DISM, e.g.:
Solaris 10 and Solaris 11 Shared Memory Locking May Fail (Doc ID 1590151.1)
Sounds like Solaris Cluster has a similar bug. A "workaround" is to reboot the (cluster) zone, that "fixes" the mlock error. This bug was introduced with updates in september, atleast to our environment (Solaris 11.1). Prior i did not have the issue and now i have to restart the entire zone, whenever i stop crs.
With 11.2.0.3 the root.sh script can be rerun without prior cleaning up, so you should be able to continue installation at that point after the reboot. After the root.sh completes some configuration assistants need to be run, to complete the installation. You need to execute this manually as you wipe your oui session
Kind Regards
Thomas

HOWTO: Create 2-node Solaris Cluster 4.1/Solaris 11.1(x64) using VirtualBox

I did this on VirtualBox 4.1 on Windows 7 and VirtualBox 4.2 on Linux.X64. Basic pre-requisites are : 40GB disk space, 8GB RAM, 64-bit guest capable VirtualBox.
Please read all the descriptive messages/prompts shown by 'scinstall' and 'clsetup' before answering.
0) Download from OTN
- Solaris 11.1 Live Media for x86(~966 MB)
- Complete Solaris 11.1 IPS Repository Image (total 7GB)
- Oracle Solaris Cluster 4.1 IPS Repository image (~73MB)
1) Run VirtualBox Console, create VM1 : 3GB RAM, 30GB HDD
2) The new VM1 has 1 NIC, add 2 more NICs (total 3). Setting the NIC to any type should be okay, 'VirtualBox Host Only Adapter' worked fine for me.
3) Start VM1, point the "Select start-up disk" to the Solaris 11.1 Live Media ISO.
4) Select "Oracle Solaris 11.1" in the GRUB menu. Select Keyboard layout and Language.
VM1 will boot and the Solaris 11.1 Live Desktop screen will appear.
5) Click <Install Oracle Solaris> from the desktop, supply necessary inputs.
Default Disk Discovery (iSCSI not needed) and Disk Selection are fine.
Disable the "Support Registration" connection info
6) The alternate user created during the install has root privileges (sudo). Set appropriate VM1 name
7) When the VM has to be rebooted after the installation is complete, make sure the Solaris 11.1 Live ISO is ejected or else the VM will again boot from the Live CD.
8) Repeat steps 1-6, create VM2 and install Solaris.
9) FTP(secure) the Solaris 11.1 Repository IPS and Solaris Cluster 4.1 IPS onto both the VMs e.g under /home/user1/
10) We need to setup both the packages: Solaris 11.1 Repository and Solaris Cluster 4.1
11) All commands now to be run as root
12) By default the 'solaris' repository is of type online (pkg.oracle.com), that needs to be updated to the local ISO we downloaded :-
+$ sudo sh+
+# lofiadm -a /home/user1/sol-11_1-repo-full.iso+
+//output : /dev/lofi/N+
+# mount -F hsfs /dev/lofi/N /mnt+
+# pkg set-publisher -G '*' -M '*' -g /mnt/repo solaris+
13) Setup the ha-cluster package :-
+# lofiadm -a /home/user1/osc-4_1-ga-repo-full.iso+
+//output : /dev/lofi/N+
+# mkdir /mnt2+
+# mount -f hsfs /dev/lofi/N /mnt2+
+# pkg set-publisher -g file:///mnt2/repo ha-cluster+
14) Verify both packages are fine :-
+# pkg publisher+
PUBLISHER                   TYPE     STATUS P LOCATION
solaris                     origin   online F file:///mnt/repo/
ha-cluster                  origin   online F file:///mnt2/repo/
15) Install the complete SC4.1 package by installing 'ha-cluster-full'
+# pkg install ha-cluster-full+
14) Repeat steps 12-15 on VM2.
15) Now both VMs have the OS and SC4.1 installed.
16) By default the 3 NICs are in the "Automatic" profile and have DHCP configured. We need to activate the Fixed profile and put the 3 NICs into it. Only 1 interface, the public interface, needs to be
configured. The other 2 are for the cluster interconnect and will be automatically configured by scinstall. Execute the following commands :-
+# netadm enable -p ncp defaultfixed+
+//verify+
+# netadm list -p ncp defaultfixed+
+#Configure the public-interface+
+#Verify none of the interfaces are listed, add all the 3+
+# ipadm show-if+
+# run dladm show-phys or dladm show-link to check interface names : must be net0/net1/net2+
+# ipadm create-ip net0+
+# ipadm create-ip net1+
+# ipadm create-ip net2+
+# ipadm show-if+
+//select proper IP and configure the public interface. I have used 192.168.56.171 & 172+
+# ipadm create-addr -T static -a 192.168.56.171/24 net0/publicip+
+#IP plumbed, restart+
+# ipadm down-addr -t net0/publicip+
+# ipadm up-addr -t net0/publicip+
+//Verify publicip is fine by pinging the host+
+# ping 192.168.56.1+
+//Verify, net0 should be up, net1/net2 should be down+
+# ipadm+
17) Repeat step 16 on VM2
18) Verify both VMs can ping each other using the public IP. Add entries to each other's /etc/hosts
Now we are ready to run scinstall and create/configure the 2-node cluster
19)
+# cd /usr/cluster/bin+
+# ./scinstall+
select 1) Create a new cluster ...
select 1) Create a new cluster
select 2) Custom in "Typical or Custom Mode"
Enter cluster name : mycluster1 (e.g)
Add the 2 nodes : solvm1 & solvm2 and press <ctrl-d>
Accept default "No" for <Do you need to use DES authentication>"
Accept default "Yes" for <Should this cluster use at least two private networks>
Enter "No" for <Does this two-node cluster use switches>
Select "1)net1" for "Select the first cluster transport adapter"
If there is warning of unexpected traffic on "net"1, ignore it
Enter "net1" when it asks corresponding adapter on "solvm2"
Select "2)net2" for "Select the second cluster transport adapter"
Enter "net2" when it asks corresponding adapter on "solvm2"
Select "Yes" for "Is it okay to accept the default network address"
Select "Yes" for "Is it okay to accept the default network netmask"Now the IP addresses 172.16.0.0 will be plumbed in the 2 private interfaces
Select "yes" for "Do you want to turn off global fencing"
(These are SATA serial disks, so no fencing)
Enter "Yes" for "Do you want to disable automatic quorum device selection"
(we will add quorum disks later)
Enter "Yes" for "Proceed with cluster creation"
Select "No" for "Interrupt cluster creation for cluster check errors"
The second node will be configured and 2nd node rebooted
The first node will be configured and rebootedAfter both nodes have rebooted, verify the cluster has been created and both nodes joined.
On both nodes :-
+# cd /usr/cluster/bin+
+# ./clnode status+
+//should show both nodes Online.+
At this point there are no quorum disks, so 1 of the node's will be designated quorum vote. That node VM has to be up for the other node to come up and cluster to be formed.
To check the current quorum status, run :-
+# ./clquorum show+
+//one of the nodes will have 1 vote and other 0(zero).+
20)
Now the cluster is in 'Installation Mode' and we need to add a quorum disk.
Shutdown both the nodes as we will be adding shared disks to both of them
21)
Create 2 VirtualBox HDDs (VDI Files) on the host, 1 for quorum and 1 for shared filesystem. I have used a size of 1 GB for each :-
*$ vboxmanage createhd --filename /scratch/myimages/sc41cluster/sdisk1.vdi --size 1024 --format VDI --variant Fixed*
*0%...10%...20%...30%...40%...50%...60%...70%...80%...90%...100%*
*Disk image created. UUID: 899147b9-d21f-4495-ad55-f9cf1ae46cc3*
*$ vboxmanage createhd --filename /scratch/myimages/sc41cluster/sdisk2.vdi --size 1024 --format VDI --variant Fixed*
*0%...10%...20%...30%...40%...50%...60%...70%...80%...90%...100%*
*Disk image created. UUID: 899147b9-d22f-4495-ad55-f9cf15346caf*
22)
Attach these disks to both the VMs as shared type

The disks are attached to SATA ports 1 & 2 of each VM. On my VirtualBox on Linux, the controller type is "SATA", whereas on Windows it is "SATA Controller".
The "--mtype shareable' parameter is important
23)
Mark both disks as shared :-
*$ vboxmanage modifyhd /scratch/myimages/sc41cluster/sdisk1.vdi --type shareable*
*$ vboxmanage modifyhd /scratch/myimages/sc41cluster/sdisk2.vdi --type shareable*
24) Start both VMs. We need to format the 2 shared disks
25) From VM1, run format. In my case, the 2 new shared disks show up as 'c7t1d0' and 'c7t2d0'.
+# format+
select disk 1 (c7t1d0)
[disk formated]
FORMAT MENU
fdisk
Type 'y' to accept default partition
partition
0
<enter>
<enter>
1
995mb
print
label
<yes>
quit
quit26) Repeat step 25) for the 2nd disk (c7t2d0)
27) Make sure the shared disks can be used for quorum :-
On VM1
+# ./cldevice refresh+
+# ./cldevice show+
On VM2
+# ./cldevice refresh+
+# ./cldevice show+
The shared disks should have the same DID (d2,d3,d4 etc). Note down the DID that you are going to use for quorum (e.g d2)
By default, global fencing is enabled for these disks. We need to turn it off for all disks as these are SATA disks :-
+# cldevice set -p default_fencing=nofencing-noscrub d1+
+# cldevice set -p default_fencing=nofencing-noscrub d2+
+# cldevice set -p default_fencing=nofencing-noscrub d3+
+# cldevice set -p default_fencing=nofencing-noscrub d4+
28) It is better to do one more reboot of both VMs, otherwise I got a error when adding the quorum disk
29) Run clsetup to add quorum disk and to complete cluster configuration :-
+# ./clsetup+
=== Initial Cluster Setup ===
Enter 'Yes' for "Do you want to continue"
Enter 'Yes' for "Do you want add any quorum devices"
Select '1) Directly Attached Shared Disk' for the type of device
Enter 'Yes' for "Is it okay to continue"
Enter 'd2' (or 'd3') for 'Which global device do you want to use'
Enter 'Yes' for "Is it okay to proceed with the update"
The command 'clquorum add d2' is run
Enter 'No' for "Do you want to add another quorum device"
Enter 'Yes' for "Is it okay to reset "installmode"?"Cluster initialization is complete.!!!
30) Run 'clquorum status' to confirm both nodes and the quorum disk have 1 vote each
31) Run other cluster commands to explore!
I will cover Data services and shared file system in another post. Basically the other shared disk
can be used to create a UFS filesystem and mount it on all nodes.
