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

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,

RAC hangs when starting or stopping 2nd instance of 2 node RAC
Has anyone seen the problem with all transactions and/or logins hanging when starting or stopping the 2nd node of a 2 node RAC database. When I shut down the 2nd instance using srvctl I occasionally get errors and long delays connecting. On our larger database with instances having a very large SGAs, trying to connect you sometimes get ORA-12537 or ORA-01033. Users experience a very long hang before getting the errors. These instances have very large SGAs of about 30GB on each node.
In the log of the first instance we see messages like the following for quite a while.

Thanks in advance.I have tested with only one node and starting and stopping is much faster without any cache fusion traffic. The application is not RAC aware, it was written without regard for RAC. As you say there may be some accessing of the same block by all nodes causing RAC to remaster blocks when a node is shut down.
My concern is the length of time users are afftected when I am starting a node that has been offline for a while. With the large SGA I have, it appears users are affected adversely for several minutes, in affect causing an outage which we are trying to avoid by using RAC. -

ORA-00304: requested INSTANCE_NUMBER is busy with instance on 2-node RAC.
Hello all,
This is a 2-Node 11.2.0.1 RAC on Redhat Linux x86-64. Only one of the instances will start at any time, when I start the other one, it will give a ORA-00304 error.
Will appreciate if you could take a look at the below information and help and/or advise some best practices. For now, I would like to get both the instances up and running first.
ORA-00304: requested INSTANCE_NUMBER is busy is the error we are receiving on Node-2/Instance-2 now.
******** Node : 1 / Instance - 1 **********
SQL> select inst_id, instance_number, instance_name from gv$instance;
INST_ID INSTANCE_NUMBER INSTANCE_NAME
1 1 cvucsdb
I am defining the instance_number and SPFILE separately in the default pfile(init file).
SQL> !cat /u01/app/oracle/product/11.2.0/dbhome/dbs/initcvucsdb.ora
instance_number=1
SPFILE='+DATA/cvucsdb/spfilecvucsdb.ora'
SQL> show parameter spfile
NAME TYPE VALUE
spfile string +DATA/cvucsdb/spfilecvucsdb.ora
For further restarts I don't need to use pfile. Simple startup command works because SPFILE is already defined.
create pfile = '/tmp/inv_inst_num.ora' from spfile;
This file is pasted below so you can review all the parameters.
******** Node : 2 / Instance - 2 **********
Similarly for instance -2 , I am using the same format:
SQL> !cat /u01/app/oracle/product/11.2.0/dbhome/dbs/initcvucsdb.ora
instance_number=2
SPFILE='+DATA/cvucsdb/spfilecvucsdb.ora'
But startup gives the error.

Questions about adding a 3rd node on a 2-node RAC cluster
Hello,
I have created a 2-node cluster on 1 VMServer machine following the steps as described in RAC11gR1-OVM-template-TestConfiguration.pdf
Now want to add a third node as documented in Appendix B of this document, but this is not clear to me.
Here it is stated in step 7: "Do not run this procedure on a node with RAC software already configured.", while on the other hand step 9 says you need to run the Add Node procedure with the -noCopy option since the software is already loaded on the new node. This seems a conflicting message to me.
Can anyone clarify this?
Can't I just add a node using this procedure when you already have a 2 node cluster up and running?
Thanks,
Klaas.Klaas,
Step 7 says to run on the new node this to setup the network:
"Invoke the network configuring script in silent mode as root on the new VM:
# /u01/clone/netconfig.sh -n3
Flag -n3 means 3rd node, -n4 would be 4th node, etc. Do not run this procedure on a node with RAC software already configured."
Step 9: says to run addNode.sh, as normally in the documentation, this is run from existing cluster member. You need to add the -noCopy flag so that software doesn't get copied to the new VM, since the software is already there, it is not configured or running yet, but the software is there.
In such procedures it's often the case you need to run some commands on existing, and some on new node(s). I think the misunderstanding is that software existing on the VM doesn't mean it's running or configured.
This entire process is fully automated in the 11.2 templates. -
Kernel upgrade having ABAP+JAVA instance
Hi team,
Can you provide the procedure how to kernel upgrade for our windows system having ABAP+JAVA instance releae version 700.
Provide the links, your replies are very helpful.
Regards
BhaskarHi Bhaskar,
You can use JSPM too in this case. Otherwise if you want to do it the old fashioned way:
> Stop SAP, Database, Saprouter, listeners and all the
related services.
> The location of the kernel is /usr/sap/<SID>/SYS/exe/run
> Take a backup of the files in this location and take a
print out of the ls -ltr (This is needed to give the new files the
correct permissions)
> Overwrite all the new files to the kernel location. The
purpose is to retain the old files for which the new version is not
available.
> The permissions of the file need to be changed as they
were before.
> Restart all the processes. The kernel upgrade is
now done. System
> status will give the newer version of the kernel.>
>
disp+work
Will give the
new Kernel version.

Hi there!
I'm designing an authentication system. Two theoretical questions have evolved. I am not so sure about it. Hope you can help me out =)
1. First sign or first cipher?
What is best practice here? Is it a risk to a symmetrical cryptosystem, if there's also a hash of the plaintext available? Or should the cipher text be signed? I am afraid that this might cause a security risk for the hash: The ciphertext's entropy should be lower than the plaintext's, which might cause lower entropy of the hash value that makes it more likely to find possible collusions.
2. Challenge Response Authentication
This is an hypotectical one: Is it of matter, if a (one-side) Challenge Response Authentication is done reverse: Bob sends Alice f(RAND), Alice deciphers it and sends RAND back to Bob.
Thanks for your help!ManuelBreu wrote:
I'm sorry, my questions were not precise: By entropy I meant the ciphertext's nature that 0 and 1 will have (almost) the same likeliness, which is not the case in the plaintext. This depends very much on the nature of the cleartext. If your cleartext is alpha numeric ASCII then it is certain that the most significant bit of any byte will be a zero with some bias in the other bits (I have never looked at it so I don't know to what extent).
But you are right: I am affraid, that the uncertainty of the key might be negatively affected by fact, that there is also a hashvalue of the plaintext available.The extra information in the form of the hash means that there is less uncertainty but I would take the resultant entropy as near to the minimum of(hash entropy, key entropy, cleartext entropy). -
Hi,
I' ve got a theoretical question about the behaviour of ISL at Cisco MDS switches:
I heard, that during a transfer (a continuous sequence of frames) between a target and an initiator (each of them are on seperated switches, which are connected with only one ISL), no other end device can use the ISL. When the sequence of frames (same OX ID, RX ID) is transfered, another end device can use the ISL.
There is no "multiplexing" of the ISL.
Q1: Is this true?
Q2: If yes, what happend, if you tranfer a lot of data between one target & one initiator. Is there a congestion on the isl for all other devices?
Regards
MarkusMarkus,
The MDS doesn't transfer entire exchanges at a time on a given ISL. Meaning OXID1, OXID2 etc... It will transmit the frames as they arrive. Such that you could transfer over the ISL:
OXID1Frame1, OXID2Frame1, OXID1Frame2, OXID1Frame3
The second problem could occur in a situation in which the receiver's buffers were full and thereby the TX port on the switch egress frames out of the switch, then the Virtual Output Queue could fill up (for which there is one assigned to every input port for every output port) and eventually the TX side of the ISL would run out of buffers. To completely avoid this, you would need per flow buffer 2 buffer credits. As a note the number of and depth of VOQ was designed to help avoid this situation as explained in this whitepaper and illustrated below.

How do I change my security questions without having to answer my security questions??
Here's the deal. I'm a little drunk, just tryin to buy a good song I heard on The Voice (yeah whatever) and I can't remember my password, my email info, or my security questions. Ten minutes later and I remember my itunes password. Great right? Well, while I took note of my newfound password, I am worried that those security questions might be needed later in life. And my question is about where I was for the new year in 2000. I don't knooooww. That was 12 years ago, and quite frankly, I was probably drunk when I answered that too. So how do I go about changing those questions without having to answer them?? **

Can we have Multiple Instance on same Node in Oracle 10g RAC
Hi All,
I am planning to implement the RAC in Oracle 10g.Before that i have one doubt regarding RAC.
My question is "Can we create multiple Instance on Same node(Server) ?"
is it possible.
Any ideas or thoughts would be apperciable.
Thanks in Advance.
AnwarThis is where it is important to keep the separation between 'database' and 'instance'.
A database is the set of files that contains the data (and the redo, control files, etc). A database does nothing by itself, other than take up lots of disk space.
An instance is theCPU cycles (running software) and the memory to control the database.
In Oracle RAC, you can have as many instances controlling one database [at the same time] as you want (within reason). Each instance must be able to access the disk(s) that contains the database.
These multiple instances can be on the same computer (effectively taking up a lot of server memory and CPU for nothing) or they can be on separate computers.
If they are on separate computers, the disk subsystems must be able to be shared across computers - this is occasionally done using operating system clusterware and is the main reason why clusterware is required at all. (This is also the toughest part of the pre-requisites in setting up a RAC and is very vendor dependent unless you use ASM.)
These instances need a communication connection to coordinate their work (usually a separate network card for each computer) so they do not corrupt the disk when they are trying to access the same file, and possibly the same block, at the same time.
In a RAC configuration, instances can be added, started, running, stopped and removed independent of each other (allowing a lot of high availability) or can be started and stopped as a group.
Each instance gets it's own SID, which is in no way any different than a non-RAC SID. It's just the name of a service that can be invoked. The neat thing is that the SID
a) helps the DBA keep things straight by lettiung us talk about 'instance A' (the Oracle software to be running over on computer A) vs 'instance B' when starting, stopping and managing;
b) helps the application by providing targets that can be listed in the TNSNAMES.ORA [against one service alias], which is used by ORacle Networking to provide automated load balance or failover (instance/SID a is not available, I guess I'll try the next in the list)
Hope that helps the concept level a bit. -
Instance name and node name mismatch
We have a 3 node RAC of 11.2 on Redhat Linux 2.5. At installation, instance 2 was configured to run on node 3 and instance 3 on node 2
[oracle@cchORdb3 admin]$ srvctl status database -d cchprd
Instance cchprd1 is running on node cchordb1
Instance cchprd3 is running on node cchordb2
Instance cchprd2 is running on node cchordb3Is there a way to correct this mistake without re-install the whole thing?
Edited by: user623617 on Feb 25, 2010 7:21 AMSorry to make you waiting. Thought the thread is frozen after the question is answered.
It works now after I stopped the instances and listeners, and then started the listeners and then instances.
I also need to change tnsnames.ora and switch the password file. The former is easy to remember but hte latter could be forget, and get ORA-01031: insufficient privileges when login to cchprd2 and cchprd3 as sysdba.
Now I login and show the parameter listener
on cchprd2
SQL> show parameter listener
NAME TYPE VALUE
listener_networks string
local_listener string CCHPRD2
remote_listener string cchORdb-rac
on cchprd2
SQL> show parameter listener
NAME TYPE VALUE
listener_networks string
local_listener string CCHPRD3
remote_listener string cchORdb-rac
