Oracle Binary Currepted in One node 11g RAC

Hi Team,
/oracle(Oracle Home ) folder currepted in one node.
IBM AIX-11.2.0.1
How to reolve the same.
Thanks
Manohar.

1. take the backup of current oracle_home corrupted.
2. Tar the other node oracle_home as below, and copy it to the corrupted node.
tar cvf location <tarname>.tar oraInventory product
3. Extracted the tar on the corrupted node by delting the existing corrupted oracle_home
tar xvf /location/<name>.tar
Now, complete the Oracle RDBMS Cloning Process of the above mentioned untar done in earlier steps:
cd $ORACLE_HOME/clone/bin
Perl clone.pl ORACLE_HOME="<LOCATION>" ORACLE_HOME_NAME="OraDb10g_home1"
Run manual command of “relink all”

Rac One Node on Rac Servers

Hi Xperts
We have this environment:
2 Rac Nodes 11.2.0.3 Enterprise on Oracle Linux 5.9 .
We have one production Database on this Rac and the users ask to create two single instance on each node, something like this:
Node1 -> Rac Prod1, Single Test
Node2-> Rac Prod2, Single Dev
I want to create Rac One node for those Database (Dev, Test) and create New Diskgroups for ech database.
Can I install a Rac One node on those Server with DBCA?
Do I nedd to Install new Database Software ?
Does the installed Rac have some affectation ?
I just want to be sure about this procedure, before to do anything.
Thank you
J.A.

Hi J.A.
Yes you can! However you need to install Grid Infrastructure (GI) in cluster on both nodes, then install database software. Either during software installation or after that, DBCA would allow you to create 1) Single instance, 2) RAC database, 3) RAC One Node database. Keep in mind that RAC One Node is an option (additional license) to the Enterprise Edition of Oracle Database.
I've talked on that topic at the Bulgarian Oracle Users Group at 2011, here is the link to the presentation, you may find it useful. I might upload the videos as well if you need to have something like a proof of concept of just for your own:
http://sve.to/download/1112/
Also I would go with one disk group for both databases, as long as they share the same physical disks I don't see the point of doing that ? Having one diskgroup would allow you to utilize better you disk/space resources.
The procedure would be:
1. Install GI in cluster.
2. Install software libraries.
3. Patch up to 11.2.0.4.
4. Create RAC One Node database using either command line or using Custom Template of DBCA.
At the end of the day, if you have standard edition license you can still install GI in cluster and create single instance databases on each server. The downside of doing that is that you need to manually failover the database to remaining node in case of disaster.

Ora.reco.acfsvol.acfs only on one node on RAC on ODA

We have an ODA (old model) and by a power failure in the data center both boot disks in one node are we gone faulty.
After replacing the chassis, RAID controllers and disks (Oracle Filed Engenieer) reports crsctl stat res -t following:
[grid @ XXXXXXXXA ~] $ crsctl stat res -t
TARGET NAME SERVER STATE STATE_DETAILS
Local Resources
ora.reco.acfsvol.acfs
ONLINE ONLINE XXXXXXXXXA mounted on / cloudfs
OFFLINE OFFLINE XXXXXXXXXBvolume / cloudfs off
is that correct?
Oracle support referred me to MOS 1319263.1, but that's for Exadata ....
Thx
Christoph
(i masked the hostname)

No, this is not correct. Your resource should be online on both nodes.
What happens if you try and start the resource manually using srvctl start filesystem?
Have you checked to see if your volume is online?

Possible to move Oracle binary code from one version of RHEL to another?

Hello folks
We are stuck with a 32 bit server running Oracle 10.1.5 database as well as Oracle Application Server 10.1.x under RHEL Linux 3 AS. Due to a SAN upgrade we need to upgrade the Qlogic HBA- and mulitipath drivers but find it extremely hard to find these drivers for such an old OS, so we are forced to move to a never version of RHEL (5 ES, most likely) and maybe new hardware too.
The database and the OAS act as backends for a portal running on another server. The OAS runs OID (identity manager).
We are not worried about porting the database. But we know that the OID in the backend is somehow registered with the frontend OAS through some kind of binary ID that might have to be changed in a hundred places in the frontend. Not something you like to fool around with a dark night in a service window.
So we are looking at simply preparing a new server and move the binary code as well as data files, control files etc. from the old server into the exact same OS locations on the new server. That way, the binary IDs would be preserved.
Here my Linux skills reach their limits. I guess, Willl binary code run on another version of Linux? I guess, if the code is statically linked, it should not depend on any OS-dependent libraries, or should it? I Is Oracle statically or dynamically linked? r What if the new server has a 64 bit OS?
Any advice or comments?
Yours
Claus Jacobsen/Denmark

You are right, Nicolas, it is a pity. But it is an old legacy system which will go out of production in about one year so we just need a temporary solution
I will try your solution and maybe look around for an outdated 32-bit server if no one else has anything to add? Thanks for your advice.
Yours
Claus

Why RAW partitions are visible only on one node in RAC?

I am having 2 node RAC on Windows 2003 Server.
Can anybody tell me why the RAW partitions are visible on RAC-2 but not on RAC-1.
I Shutted down RAC-2, and I thought all the RAW devices will appear in RAC-1, but it didn't work, it is displaying only LOCAL DRIVE.
Why???

I am using Microsoft Virtual Server and I have configured SCSI type shared disks.
I executed the given command
C:\oracle\product\10.2.0\crs\bin>cluvfy comp ssa -n rac-1,rac-2
Result : Shared storage check was successful on both the nodes..
Both the nodes are working properly but I want to know the reason 'why the shared disks are not visible on node1'?
Thanks

When one node reboot other node in RAC

Hi Friends,
I faced one situation where one node of RAC cluster had been rebooted by other node. This happen due to network interconnect link fluctuation.

A network fluctuation shouldn't give reboot like this. Then why oracle design like this way? Is this a bug? My oracle version is: 10.2.0.5.0
Could you tell me the other possible situations when 1 RC instance reboots other RAC instacne.

What you are describing is the expected behaviour: if your interconnect fails, you will have a node eviction. Releases < 11.2.0.2 evict a node by reboot, which can fix the problem: the NIC may come up correctly when the machine re-starts. Releases >= 11.2.0.2 can often evict without a re-boot. But either way, if your interconnect goes down, a node must be evicted to prevent uncoordinated disc writes.
If you are interested, you can find some discussion and demos of this in a series of webcasts I've recorded,
Free Oracle Database Tutorials for Administration and Developers
If you really don't like this behaviour and the problems are transient, you can try 'raising the CSS MISSCOUNT parameter.

Can RAC and RAC One Node share the same servers ?

Does anyone know if it is possible for RAC and the new 11gR2 RAC One Node to share the same set of physical servers i.e. in effect having 2 clusters sharing the same set of servers ( though you could argue RAC One node is a different type of clustering or even that it is not real clustering at all - more instance transporting ).
Or does standard RAC always require exlusive use of the physical servers it is using as its nodes ?
Any thoughts appreciated
Jim

Hi Jim,
To deploy RAC we need Oracle Grid Infrastructure for a cluster (aka Oracle Clusterware) on top.
What determine if it's Single /RAC /RAC one Node is the Installation of Oracle Database.
So, Oracle Clusterware support on Same Cluster ( RAC/ RAC one Node / Single).
You will need one installation for each Feature.
e.g on Same Cluster
---> Grid Infrastructure GRID_HOME=/u01/app/11.2.0/grid
--->> RAC one Node /ORACLE_HOME = /u01/app/oracle/product/11.2.0/racone_11203
--->> RAC /ORACLE_HOME = /u01/app/oracle/product/11.2.0/rac_11203
--->> SINGLE /ORACLE_HOME = /u01/app/oracle/product/11.2.0/db_11203
For me make no sense RAC ONE NODE and RAC on same cluster.
Because RAC ONE NODE is a RAC with less feature.

11g RAC on VMware

Hi,
I am trying to install 2 node, 11g RAC on VMware, the installation went fine on node 1, but node 2 had issues with ASM and DB... The problem is the ASM and DB home installed successfully, but the ASM2 and DB (RAC2) instance are not up on node 2. Actually the ASM1 and RAC2 are not registered in CRS. I will upload the exact error in a short time. While installing I got the error for node-2, that it is unable to find the ASM disks, but when I executed this " /etc/init.d/oracleasm listdisks " on node 2, it shows VOL1,VOL2.
Any help would be much appreciated.

Hi All,
I have been through all the links you people gave me, those were really helpfull, thanks. The problem is resolved now. Actually the issue was, ASM2 instance could not detect the disks for some reason, after some research in metalink I found a note:457369.1 and as per the note I included *" asm_diskstring = /dev/oracleasm/disks/* "* perameter in the init.ora file of ASM2. Then it detected the diskgroup and everything is fine now. Actually this issue is a bug in 10g, unfortunately it is not fixed in 11g as well.
Thank you all for your help.
Regards,
Satya.

Can I move sessions from one node to another in Oracle RAC 11g?

Hi everybody,
When I need to shutdown one node for maintenance, can I move the sessions connected to that node to the other one? I know TFA but I'm not using it right now, I just wanted to know if I may move the sessions without warning everyone that some of them will be disconnected.
Thanks for your help.

sol.beach, thanks for your answers, just a few words:
When you answered "NO, shutting down a node will disrupt every session on that node". it was confusing, as I wasn't asking for the behavior of the sessions when the node is shut down, you should've answered "NO, there's no way to manually relocate a session", that would have been clear since the beginning, also asking me to post a SQL didn't help much either, I honestly thought I didn't explain well my doubt.
Thanks anyway.
The answer is a no but the question for you, why you want to do that anyways?

I tried reinstalling again and it worked on Vmware Server.Some oracle products are certified on Oracle VM , but not RAC at the moment.
You can download Oracle VM from otn.oracle.com
Check ML Note:464754.1 for details about Certified Software on Oracle VM.

Oracle RAC one node

why Oracle introduced Oracle RAC one node in 11gR2?
I have gone through oracle documents on oracle rac one node, but i couldn't find much added advantage than instance failover. We have already some technologies like datagaurd and some third party softwares for instance failover.
Then why oracle introduced this RAC one node in the new release i.e 11gR2?
What exactly oracle wants to provide from oracle RAC one node?
Thanks...
Bharath

Why RAC one node?
Oracle RAC one node is a single instance of Oracle RAC that runs on the node in a cluster. The benefit of the RAC one node option is that it allows you to consolidate many databases into one cluster without a lot of overhead, while also providing high availbilty benefits of failover protection, as well as for Online rolling patch application and rolling upgrades for the Oracle clusterware.
Another aspect of RAC one node allows you to limit th CPU utilization of individual database instances within the cluster through a feature called resource manager instance caging, which gives you the ability to dynamilcally change the limit as required.
Furhtermore , with RAC one node there is no limitation for server scalabilty such that if applications outgrow the current resources than a single node can supply, you can then upgrade the applications online to Oracle RAC.
In tthe event that the node which is runnig Oracle RAc one node becomes saturated and out of resources, you can migrate the instance to another node in the cluster using Oracle rac one node and another new utilty called OMOTION feature.OMOTION feature for Oracle RAC 11g R2 rac allows you to migrate a running instance to another server without downtime or distrubtion in service for your enviornment.
Hope you're understand.

Oracle Applications 11i Load Balancing does not work with RAC one Node

Hi all,
Could you help me to resolve this issue.
Architecture environment is :
- One APPS tier node
- Two nodes Oracle Database Appliance (Primary node 1 holds INSTANCE_1 et Secondary node is configurured to holds INSTANCE_2), i.e RAC one Node.
- The primary node have instance_name SIGM_1 and the secondary node have instance_name SIGM_2, but in RAC one node, the secondary instance is not alive.
We convert our EBS 11i environment to RAC following note ID Using Oracle 11g Release 2 Real Application Clusters with Oracle E-Business Suite Release 11i [ID 823586.1].
When testing Database failover, Oracle Applications 11i load balancing does not work anymore.
The root cause is that, when the primary node of the Rac one node is down, the INSTANCE_NAME_1 is automaically relocating to the surviving node,.
During test failover, we imagine that when the primary node goes down, the secondary node start or relocate database with instance_name SIGM_2, and in that case the Oracle Applications load balancing works.
Currently, when the primary node goes down, the instance_name SIGM_1 is relocated on the secondary node, which cause failure of Oracle Applications Load Balancing.
Thank you for your advice.

This is something I observed a long time ago for Safari (ie: around version 1). I'm not sure this is Safari, per se, but OpenSSL that is responsible for the behavior. I'm pretty sure Chrome does this and I've seen some Linux browsers do it.
What I have done at the last two companies I've worked for is recommend that our clients do not use SSL SessionID as the way of tracking sticky sessions on web servers, but instead using IP address. This works in nearly all cases and has few downsides. The other solution is to use some sort of session sharing on your web servers to mitigate the issue (which also means that your web servers aren't a point of failure for your users' sessions). (One of the products I supported had no session information stored on the web servers, so we could safely round-robin requests, the other product could be implemented with a Session State Server... but in most cases we just used IP address to load balance with). The other solution is to configure your load balancer to terminate the SSL tunnel. You get some other benefits from this, such as allowing your load balancer to reduce the number of actual connections to the web servers. I've seen many devices setup this way.
One thing to consider through this is that - due to the way internet standards work - this really can't be termed a bug on anyone's part. There is no guarantee in the SSL/TLS standards that a client will return the same SSL Session ID for each request and there is not requirement that subsequent requests will even use the same tunnel. Remember, HTTP is a stateless protocol. Each request is considered a new request by the web server and everything else is just trickery to try and get it to work the way you want. You can be annoyed at Safari's behavior, but it's been this way for over 5 years by my count, so I don't expect it to change.

Install Oracle 11G, RAC with VMWare, APPS R12, and OBIEE on one server?

Dear Experts,
I'm looking to upgrade my skills, and want to learn more of:
Oracle 11G, RAC, VMWare, APPS R12, and OBIEE
My server has two quad cores (8 CPU altogether) and 16 gigs of RAM.
Years ago, I took a shots at installing RAC on multiple servers and firewire.
One thing I remember was that after I installed RAC, I was not able to use the database unless I enabled all the RAC processes on the server. So, I was not able to just boot the database and use it in the traditional single server manner.
Which I will also want to do.
1) Does this symptom/aspect/characteristic of RAC install still exist?
2) Is it realistic to install all this software on one server?
If so, what is the order of operations for the install?
3) If I have to prioritize, I'd like to install
Oracle 11G, OBIEE, and APPS R12,
Would installing R12 and OBIEE on the same server present any conflicts or issues?
If not, what is the order of operations for the install?
11G, R12, then OBIEE?
Thanks a lot!

Hi,
1) Does this symptom/aspect/characteristic of RAC install still exist?No.
2) Is it realistic to install all this software on one server?
If so, what is the order of operations for the install?For learning/traning/demonstration purpose you can Install all these software on same machine.
3) If I have to prioritize, I'd like to install
Oracle 11G, OBIEE, and APPS R12,
Would installing R12 and OBIEE on the same server present any conflicts or issues?
If not, what is the order of operations for the install?
11G, R12, then OBIEE?There will not be any conflicts. I would suggest you to select vmware or virtual box in order to configure all these sw's.
I have done such a configuration on my laptop with i7 Quad processor, 16GB RAM and 640 GB HDD.
I have Installed 2 node RAC, 2 Node ERP and all are running smoothly without any issues.
