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
psdbsrv1 PREF: psdb1 psdb2 AVAIL:
Thanks,
MM

Application is using the following connection string.
jdbc:oracle:thin:@(DESCRIPTION =(ADDRESS = (PROTOCOL = TCP)(HOST = PQ2-PS-db-01-vip)(PORT = 1521))(ADDRESS = (PROTOCOL = TCP)(HOST = PQ2-PS-db-02-vip)(PORT = 1521)) (LOAD_BALANCE = yes) (CONNECT_DATA =(SERVER = DEDICATED)(SERVICE_NAME = PSDBSRV1)(FAILOVER_MODE =(TYPE = SELECT)(METHOD = BASIC)(RETRIES = 180)(DELAY = 5))))

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.

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.

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

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

What is the reason for a "+just in case+" node - and when and how is is "enabled" when that just-in-case situation occurs?
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.
Basic example:
// note that this TEST-RAC alias refers to a single specific IP of a cluster, and use
// SERVICE_NAME as the request

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.

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

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

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

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.

How can i get a specific tone for my vip email alert. all tones are in my ringtones, but only some show up in the alerts for email.

i cannot get my all my ringtones to transfer to my vip email alerts. there is a specific tone I need for one vip email alert, but that one doesn't transfer, however it IS in my ringtones and textones. how can I get that particular tone for my vip email?

Only Apple Account Security could help at this point. You can try calling Apple Support in Canada - you'll have to find one of the several ways, such as Skype, to call an 800 number from outside of the relevant country - and ask for Account Security and see if they can help. Or you can find a friend who speaks Chinese and ask them to help you talk to Apple Support in China. There are really no other options that I know of.
Note, by the way, that these are user-to-user support forums. You aren't speaking with Apple when you post here.

2. When I read ... "Version 11.1.0.7.0" ... I wonder to myself ... why not apply all of the patches Oracle has created in the last 3 years and see if having a fully patched version addresses the issue?
3. When I read ... "parallel query server died" ... I wonder whether you have gone to support.oracle.com and looked up the causes and solutions for Parallel Query Server dying?
Of course I also wonder why you have an 8 node cluster as that is adding substantial complexity and which leads me to wonder ... "is it happening on only one node or all nodes?"
Hope this helps.

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?

Thanks in Advance

you should have to user some other new ips for VIP.
PLEASE CHANGE THE VIP IP's and try again.
192.168.2.131 rac1-vip.sun.com rac1-vip
192.168.2.132 rac2-vip.sun.com rac2-vip
192.168.2.133 rac3-vip.sun.com rac3-vipchange the ips to some other ip not used by any machines.

OCR and Votinging Disk File Permissions for NFS 2 node RAC cluster

This is a fresh reinstall of Oracle 11gR2 Clusterware on Red Hat Enterprise Linux 64bit and I'm using NFS as my shared storage.
I've create three file systems /ocrVote01 /ocrVote02 and /ocrVote03 as NFS share and exported them to two nodes that will use them as shared OCR and Voting Disk. Currently I'm getting errors when I run root.sh
I've done the following:
chown rac:dba -R /ocrVote01 /ocrVote02 /ocrVote03
It appears that the root.sh script is trying to create a directory /ocrVote01/storage and getting permissions denied.
Any idea why Root can not create this directory?
root.sh is also getting error permission denied at /u01/gridinfra/11.2.0/GI/crs/install/crsconfiglib.pm at line 4478
Any Ideas on what file permissions should be set for /ocrVote01 /ocrVote02 and /ocrVote03 ?
Thanks

32352 exit_group(25) = ?

After reading OTN feedback, which is very much appreciated. I decided to look deeper into my NFS configuration and found that the /etc/exports had the incorrect configuration for shared disk where in root can make appropriate changes to voting disk and crs files. The correct configuration for /etc/fstab using NFS for shared storage for voting disk and CRS:
192.168.1.21:/ocrVote01 /ocrVote01 nfs rw,bg,hard,nointr,rsize=32768,wsize=32768,tcp,vers=3,timeo=600,actimeo=0 1 2

192.168.1.21:/ocrVote03 /ocrVote03 nfs rw,bg,hard,nointr,rsize=32768,wsize=32768,tcp,vers=3,timeo=600,actimeo=0 1 2
