Automatic restart of services on a 1 node rac cluster with Clusterware

How do we enable a service to automaticly start-up when the db starts up?
Thanks,
Dave

srvctl enable service -d DBThanks for your reply M. Nauman. I researched that command and found we do have it enabled and that it only works if the database instance was previously taken down. Since the database does not go down on an Archiver Hung error as we are using FRA with an alt location, this never kicks in and brings up the service. What we are looking for something that will trigger off of when the archive logs error and switch from FRA(Flash Recovery Area) to our Alternate disk location. Or more presicely, when it goes back to a Valid status(on the FRA - after we've run an archive log backup to clear it).
I found out from our 2 senior dba's that our other 2 node rac environment does not suffer from this problem, only the newly created 1 node rac cluster environment. The problem is we don't know what that is(a parameter on the db or cluster or what) and how do we set it?
Anyone know?
Thanks,
Gib

All connections are connecting to 2nd node only in a 2 Node RAC Cluster

Hello,
I have a 10.2.0.3 database on a two node RAC Cluster with only one service configured. This service set to be preferred on both nodes.
However, all the connections are falling on Node2 only. Any idea where to look.
$> srvctl config service -d PSDB

Application is using the following connection string.

Multiple databases/instances on 4-node RAC Cluster including Physical Stand

OS: Windows 2003 Server R2 X64
DB: 10.2.0.4
Virtualization: NONE
Node Configuration: x64 architecture - 4-Socket Quad-Core (16 CPUs)
Node Memory: 128GB RAM
We are planning the following on the above-mentioned 4-node RAC cluster:
Node 1: DB1 with instanceDB11 (Active-Active: Load-balancing & Failover)
Node 2: DB1 with instanceDB12 (Active-Active: Load-balancing & Failover)
Node 3: DB1 with instanceDB13 (Active-Passive: Failover only) + DB2 with instanceDB21 (Active-Active: Load-balancing & Failover) + DB3 with instanceDB31 (Active-Active: Load-balancing & Failover) + DB4 with instance41 (Active-Active: Load-balancing & Failover)
Node 4: DB1 with instanceDB14 (Active-Passive: Failover only) + DB2 with instanceDB22 (Active-Active: Load-balancing & Failover) + DB3 with instanceDB32 (Active-Active: Load-balancing & Failover) + DB4 with instance42 (Active-Active: Load-balancing & Failover)
Note: DB1 will be the physical primary PROD OLTP database and will be open in READ-WRITE mode 24x7x365.
Note: DB2 will be a Physical Standby of DB1 and will be open in Read-Only mode for reporting purposes during the day-time, except for 3 hours at night when it will apply the logs.
Note: DB3 will be a Physical Standby of a remote database DB4 (not part of this cluster) and will be mounted in Managed Recovery mode for automatic failover/switchover purposes.
Note: DB4 will be the physical primary Data Warehouse DB.
Note: Going to 11g is NOT an option.
Note: Data Guard broker will be used across the board.
Please answer/advise of the following:
1. Is the above configuration supported and why so? If not, what are the alternatives?
2. Is the above configuration recommended and why so? If not, what are the recommended alternatives?

Hi,
As far as i understand, there's nothing wrong in configuration except you need to consider below points while implementing final design.
1. No of CPU on each servers
2. Memory on each servers
3. If you've RAC physical standby then apply(MRP0) will run on only one instance.
4. Since you are configuring physical standby for on 3rd and 4th nodes of DB1 4 node cluster where DB13 and DB14 instances are used only for failver, if you've a disaster at data center or power failure in entire data center, you are losing both primary and secondary with an assumption that your primary and physical standby reside in same data center so it may not be highly available architecture. If you are going to use extended RAC for this configuration then it makes sense where Node 1 and Node 2 will reside in Datacenter A and Node 3 ,4 will reside in Datacenter B.
Thanks,

3 Node Failover Cluster With iSCSI

Is there any information available on the steps to create a 3 node failover cluster with iSCSI storage? Is there a step-by-step guide? I looked around but couldn't find much. Thanks!

Install mulutple RAC databases on 2-node RAC cluster

I am installing 5 RAC databases on a 2-node RAC cluster. I have setup SCAN using 3 IP addresses.
Do I have to use SCAN listener for all databases?
When installing the 3 database, I get ORA-12537: TNS connection closed error.
ENV: 11gR2 2-node RH5.x
Thanks!

I have setup SCAN using 3 IP addresses.
Do I have to use SCAN listener for all databases?These 3 scan ip will work for youe all database running under this cluster setup.
you may also use VIP to make connection like 10g.
I get ORA-12537: TNS connection closed error.Appear some connectivity/configuration isue,please try MOS doc contain detail on this.

Modifying a service in a 3-node RAC database

Hello,
I have a 3-node rac 10.2.0.4 here under Windows 2003 x64.
I created, months ago, a service that have 1 preferred instance, and 1 available instance.
Now I have to change it, so it does not have an available instance anymore, just 1 preferred instance, because the client wants it to run only on this node.
After looking up in the 10.2 manual, I could not find the exact command to accomplish the job. Have you done this and can you shed a light ?
Thanks.

Hi, thanks for your answer, but no, each node has 2 instances only, ASM and Database.
But they changed their minds, instead of keeping togheter the service SRV3 on NODE3, now we need that, when NODE3 restart or something, and come back, the service be relocated to NODE3.
This does not happen automatically, Oracle says we have to code the "srvctl relocation" command using some callback mechanism to automate fallback. Is there an url or paper or so that explains how to do it ?
Thanks.

Theoretical question on having "stand by" instance on 4 node RAC cluster.

We have been having discussions on how we can improve the overall stability and performance of our RAC cluster. Currently we are running multiple databases on a 2 node cluster. The idea is that we will add two more nodes to the cluster and then spread the instances across the 4 nodes but only have two active and 1 as a standby in the event of node failure.
In other words:
Node1, Node2, and Node3 would run DB1
Node 4 Node3 and Node2 would run DB2
Additionally DB1_Instance3 would be shutdown on Node3 and only started if Node1 or 2 failed.
This would be the same for DB2 where DB2_Instance3 on Node2 would only be started if Node3 or Node4 failed.
Underneath them all would be the same ASM database shared for all 4 nodes.
Has anyone seen such a configuration? Is anyone aware of a white paper that discusses it.

the parameter active_instance_count is a 9i parameter and should only be set if you want to run RAC with a 2 node cluster - one instance active (all users connected here) and the second instance up but no one actively using it. IF instance one goes away, all work is move to instance 2. This is hot failover .
If you are adding a new instance to a rac database, you are recommended to use DBCA or EM to add the instance. If you do not want to have users connected to the instance all the time, you can either leave it running but do not enable any services on it until you need it or stop the instance with srvctl stop instance. The cluster will not try to restart the instance automatically.
The services option, when you create a service, you define which instances you wish it to run on. You can dynamically change where it runs. For the end user, they just connect to the service, the listener directs the connection to the least loaded instance providing the service at connect time. See the workload management with RAC 10g white paper on otn (otn.oracle.com/rac) or Chapter 6 of admin & deploy guide

Routing all connections through a one node in a 2 node RAC cluster

Hi everyone
My client has the following requirement: an active/active RAC cluster (eg node1/node2), but with only one of the nodes being used (node1) and the other sitting there just in case.
For things like services, i'm sure this is straightforward enough - just have them set to preferred on node1 and available on node 2.
For connections, I imagine I would just have the vips in order in the tns file, but with LOAD_BALANCING=OFF, so they go through the tns entries in order (i.e node 1, then node 2), so this would still allow the vip to failover if node 1 is down.
Does that sound about right? Have I missed anything?
Many thanks
Rup

This does not many any kind of sense from a high availability or redundancy view.

Does that sound about right? Have I missed anything?Won't work on 10g - may not work on 11g. The Listener can and does handoff connections, depending on what the TNS connection string say. If you do not connect via a SID entry but via a SERVICE entry, and that service is available on multiple nodes, you may not (and often will not) be connected to instance on the single IP that you used in your TNS connection.

SQL> So we connected to RAC node 196.1.83.116 - and that listener handed us off to RAC node 196.1.83.127. The 11gr2 Listener seems to behave differently - it does not do a handoff (from a quick test I did on a 11.2.0.1 RAC) in the above scenario.
This issue aside - how do you deal with just-in-case situation? How do you get clients to connect to node 2 when node 1 is down? Do you rely on the virtual IP of node 1 to be switched to node 2? Is this a 100% safe and guaranteed method?
It can take some time (minutes, perhaps more) for a virtual IP address to fail over to another node. During that time, any client connection using that virtual IP will fail. Is this acceptable?
I dunno - I dislike this concept of your client of treating the one RAC node as some kind of standby database for a just-in-case situation. I fail to see any logic in that approach.

Failover takes 14 minutes on 2 node rac cluster installed on virtualbox

i have 2 node rac 10gr2 installation without asm on virtualbox for learning purposes, the storage is kept on rac1 node and shared via nfs,
i connected a third machine to be used as client by creating a service
but when i shutdown the rac2 node to cause a failover, it takes almost 14-15 minutes to reconnect to the rac1 node
even though the vip of rac2 is taken up by rac1 in not more than 30 seconds
so i checked the listener log for rac1 node
the correct service update shows up after 14 minutes every time i try
tried a lot of googling but found nothing

How to make 2 Node File Cluster with SAS Disks

Hello,
I cant fine any detailed, specific information and answer on this question
I have 2 Servers, Say HP, with 4 SAS disks each, 1 for OS (2012R2Data) and 3 available.
I want to create fault tolerant SMB 3.0 share for my Hyper-v nodes, to make hyper-v FT cluster afterwards.
So, I see inr equirements that SAS disks will work, but during creating cluster, I can not manage Cluster to see disks from both servers (total 6 free units)
If it is made via ISCSi target, both servers have access to that targets and cluster sees all available through iSCSI disks, but how to mnake SAS disk available to other server?
Is it possible what I need with this configuration? is it a option to make each server iSCSI target and initiator? (but it would be way complicated and slow, I think).
so, what I have misunderstood, how to make FT file Cluster with 2 servers with SAS drives?
Any info about this SPECIFIC config would be welcomed, or any general step-by-step guides (please, do not link me guides with other config, like iscsi or with additional servers, I have seen a lot of them :()
thanks

You cannot do what you want with a Microsoft built-in tools. MSFT require you to take your SAS disks away from your servers, buy a SAS JBOD (better more then one to get advantage of a so-called "enclosure awareness" and avoid single point of failure) and
configure Clustered Storage Spaces with now *external* SAS drives. See:
How to Configure a Clustered Storage Space in Windows Server 2012
http://blogs.msdn.com/b/clustering/archive/2012/06/02/10314262.aspx
Prerequisites
A minimum of three physical drives, with at least 4 gigabytes (GB) capacity each, are required to create a storage
pool in a Failover Cluster.
The clustered storage pool MUST be comprised
of Serial Attached SCSI (SAS) connected physical disks. Layering any form of storage subsystem, whether an internal RAID card or an external RAID box, regardless of being directly connected or connected via a storage fabric, is not supported.
Windows Server 2012 R2 had flexed out some limitations so now ReFS is supported (but useless as VMs cannot be integrity checked and protected) and now you can use parirty spaces (also useless as they are DOG slow with a typical VM workload dominated by small
writes, say 4KB write initiates 256KB+ parity stripe read-modify-write update). Core requirements "SAS everywhere" is still there.
So if you don't want to mess with SAS JBODs you may give a try to a virtual SAN solutions available on the market. They can cluster a pair of hosts (even with a single port SATA drives) w/o any external hardware, only Ethernet required. There are even free
options available. See:
Free Virtual SAN
http://www.starwindsoftware.com/native-san-for-hyper-v-free-edition
Also Google (or Bing?) for DataCore and SteelEye as they have very similar native (Windows-based) offerings. + there's bunch of a VM-running storage doing more or less the same.
Hope this helped a bit :)
StarWind VSAN [Virtual SAN] clusters Hyper-V without SAS, Fibre Channel, SMB 3.0 or iSCSI, uses Ethernet to mirror internally mounted SATA disks between hosts.

Diff hardwares for 2 node rac cluster

Dear All,
Can i implement RAC 2 node cluster on 2 nodes with diff hardwares like diff server models?

Hi,
Also you can read tech note below:
*RAC: Frequently Asked Questions [ID 220970.1]*
Can I have different servers in my Oracle RAC? Can they be from different vendors? Can they be different sizes?
Oracle RAC does support a cluster with nodes that have different hardware configurations. An example is a cluster with 3 nodes with 4 CPUs and another node with 6 CPUs. This can easily occur when adding a new node after the cluster has been in production for a while. For this type of configuration, customers must consider some additional features to get the optimal cluster performance. The servers used in the cluster can be from different vendors; this is fully supported as long as they run the same binaries. Since many customers implement Oracle RAC for high availability, you must make sure that your hardware vendor will support the configuration. If you have a failure, will you get support for the hardware configuration?

SOA with Oracle 2 node RAC cluster

Hi All,
Just a simple doubt, I have successfully installed and configured SOA suite 11.1.1.3 & BAM in one wls Domain 10.3.3 in a linux box and could access all the application like BAM console, BPEL console etc .... also could see all my data-sources deployed in the Data Sources with a single node database.
1. Now I have to RE-configure this whole SOA suite with RAC (2 node database cluster) what changes or configuration needed to implement SOA suite with RAC database?
2. Do I need to create a "Multi Data Source" to configure RAC with SOA suite..?
Thanks
Sam

This is regarding Oracle RAC..so if there is a specific category..please let me know..
I have installed OEL linux 5.6 as guest OS (using virtualbox) in two laptops.
I want to install 2 node oracle 10gR2 RAC with the OEL linux as OS and each laptop as one node.
Read docs and understood that there must be shared storage for oracle clusterware and oracle ASM for oracle RAC to work.
Please let me know the steps to create shared storage for oracle clusterware and oracle ASM (considering virtualbox OEL) and to configure public,private and virtual IPs.
I already have document to create 2node oracle RAC using virtualbox with two nodes on the same laptop.so please dont suggest that doc.
Thanks,
DBMay be my step by step RAC installation guide can help you somehow?

How should I start, stop or restart SQL services if it is in a cluster?

Hi,
For migration purpose I need to stop sql server services in a cluster. I don't want to failover the cluster I just want to stop the sql server services before the windows system admin shutdowns the windows server and later start again once migration is done.
This is clone migration so I don't have to do anything except stopping and starting the services of sql. I found two places there to take service offline and online, one is just clicking the services and application and in the right hand side directly right
clicking the instance and take service offline, another is expanding the instance and taking offline agent and sql server service one by one.
I don't know which is the way.
Please some one help me.

Hello,
You can use SQL Server Configuration Manager, SQL Server Management Studio, Cluster Administrator.
Do not use the Services applet in Control Panel.
Hope this helps.

2 node rac cluster - continuous reboot

i have semi-successfully installed oracle clusterware on 2 nodes........... had trouble with the last screen running root.sh and orainstRoot.sh (whatever).
Now, what i have is the continuous reboot of 2 nodes............... i have tried restarting them at exactly the same time but the 1 node reboot as soon as you log in to the node.......... the other node just reboots at some stage.
So, how to resolve ?
I am using openfiler 2.2; enterprise linux 5.0 installing oracle 11.1.0.6.
I am following the instructions as posted on the otn.oracle.com website.........
My last step was to deinstall the clusterware software as it had issues during final stage of starting ONS and GND (or whatever). I had to reboot after removing the software and that is when continuous reboot cycle started.
Any help appreciated.....
THIS IS JUST A DEMO SYSTEM but still i would like to get it working as quickly as possible.

I think Your system reboot.., Because CRS on Oracle Cluster Software had the problem... you should check logs at $ORA_CRS_HOME/log/<nodename>/*/ ... (about heart beat)
If you have problem reboot ... when you removing software ,you have make sure you stop RAC processes
ps -ef | grep init | grep crsAnyway If you don't need to RAC processes start, when you restart server...
You should comment on /etc/inittab file ()
#h1:35:respawn:/etc/init.d/init.evmd run >/dev/null 2>&1 </dev/null
#h2:35:respawn:/etc/init.d/init.cssd fatal >/dev/null 2>&1 </dev/null
#h3:35:respawn:/etc/init.d/init.crsd run >/dev/null 2>&1 </dev/nullOr disable...
10gR1
/etc/init.d/init.crs disable
/etc/init.d/init.crs stopabove 10gR2
$ORA_CRS_HOME/bin/crsctl disable crs
$ORA_CRS_HOME/bincrsctl stop crsAbout Your System reboot, when on Oracle Cluster... You should check log... , HeartBeat (Interconnect and Disk (CRS File and Voting File))
Anyway Contact Oracle Support
Finally, You should installed RAC... If you find system reboot ... You should disable crs, and then investigate the problem (Check Log $ORA_CRS_HOME/log/<nodename>/crsd/*)
Good Luck

Guest two node Failover Cluster with SAS HBA and Windows 2012 R1

Hi all, i have two IBM x3560 brand new servers with V3700 IBM Storage. The Servers are connected to the storage through four SAS HBA adabters (two HBA's on each server). I want to create a two node guest Fileserver Failover Cluster. I can present the
LUN's to the guest machines, but when i 'm running the cluster creation wizard it can't see any disk. I can see the disks on disk management console. Is there any way to achive this (the cluster creation) using my SAS HBA presented
disks, or i have to use iSCSI to present the disks to my cluster?
Thank you in advance, George

1) Update to R2 and use shared VHDX which is a better way to go. See:

2) If you want to stick with non-R2 (which is a BAD idea b/c tons of reasons) you can spawn an iSCSI target on top of your storage, make it clustered and make it provide LUs to your guest VMs. See:
iSCSI Target in Failover

3) Use third-party software providing clustered storage (active-active) out-of-box.
I would strongly recommend to upgrade to R2 and use shared VHDX.
