CRS & RAC with 3 node

Hi EveryBody,
I am planing to install the Rac in my home, i mentioned the following information below.
i am using 3 system with windows 2000 server, i wan to install the oracle 10gR1 RAC.
my question is, for all nodes they need to install the CRS software ???? or one system is enough, and the same time what about the rac software, its enogh to install in one node or install in all node????
senthil

All nodes will will connected to each other with private IPs.......and you just need to install Clussterware and RAC from one node and add those nodes in your installtion. Oracle will install everything on its own on other nodes.
Hope this helps
Luck
Regards

Install CRS and RAC with different users

I' m tring to install CRS and RAC with different users.
It is supported but I don't find documentation.
Have someone experience with this configuration ?
My question are related to permission/own of voting and ocr file.
in this configuration is CRS owner or DB owner that run srvctl commands ?
Thanks !

Yes it is ... check out the RAC FAQ on metalink, and just as Chris metioned the users will need to have the oinstall group as their primary..
"Is it supported to install CRS and RAC as different users.
Yes, CRS and RAC can be installed as different users. The CRS user and the RAC user must both have "oinstall" as their primary group, and the RAC user should be a member of the OSDBA group.

Oracle RAC one node-11.2.0.1 with patch 9004119

Hi,
I'm slightly stuck here. I have successfully converted 11.2.0.1 2 node RAC to RAC one node with patch *9004119*(which has scripts required for racone). My single instances are up and running, relocation of databases go fine
As i launch my OEM, it pops with +"ORA-12505:TNS:listener does not currently know of SID given in connect descriptor".+ . Obviously, ./Raconeinit renames the DB instances, but doesn't get changed in OEM. It still lists my old instances.
I manually change ORACLE_SID to new instances in all my nodes, so i'm able to connect through sql, but how do i configure it in DB control so that the change is seen universally. Any application i run with the new instance gives me the above mentioned error.
Please respond!

Hi,
In continuation with my above query, i did some search and looked at 'raconeinit' script. It's basically trying to run certain commands to see the current server, free server, current running DB , stores the value in a variable and validates against the input I provide, which is not happening.
When i manually try to run the commands mentioned in script, it gives me invalid -i and -f options errors.
to see DB up:
+./crsctl status resource ora.$LOWER_DB_NAME.db | $GREP -i "^STATE" | $GREP -i "ONLINE" | $WC -l+
to see current server
+./crsctl status resource ora.$LOWER_DB_NAME.db | $GREP -i "STATE" | $AWK -F'ONLINE on ' '{print $2}'+
to see free servers
+./crsctl stat serverpool Free -v|$GREP -i active_servers|$AWK -F'=' '{print $2}'+
It is not accepting my input (free server) and hence exiting. :(

Database upgrade - Oracle 10g r2 ,RAC(2 Nodes with ASM) upgrade from HP-UX to RHEL 5.9

Hi All
I am planning to upgrade our RAC database 2 nodes with ASM from HP-UX to RHEL 5.9.
Following is our setup
Current setup:
Oracle Database 10g r2 (10.2.0.5.0) RAC database.
Nodes: 2
Storage: ASM
OS: HP-UX ia64
Database Size: 1.2 TB
New Setup:
Oracle Database 10g r2(10.2.0.5.0) RAC database
Nodes: 2
Storage: ASM
OS: RHEL 5.9 x86 64
Since we are moving from a big endian format to a small endian format(HP-UX to RHEL 5.9) the same ASM cannot be used.
Kindly help me with process and other important documents to be followed.
Thanks.

Hi...
If it was a standlone database concepts like transportable tablespaces, rman would have been convenient.
Since we are using a RAC database with ASM as storage how do we use these techniques specified in NOTE:733205.1
Due to endianness issue we cannot use the same ASM instance.
Along with the new RAC node install a new ASM instance would have to be created.
Kindly help me with migration for RAC with existing ASM to new Hardware
Thanks and Regards

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.

Oracle RAC with more then two nodes?

Hello,
knows anybody a reference client project that use Oracle RAC with more then two nodes on a Linux environment?
Many thnaks!
Norman Bock

Hello Norman,
XioTech is a SAN company that has a project called "THE TENS". They configured and ran a 10 node RH Linux Oralce 9i RAC. I understand they want to see if 32 are possible. I am sure if you ask them, they would be happy to give you the details.

How do i licence a two node RAC with ASM infrastructure

AM trying to estimate the licensing of two node RAC with ASM as storage manager and GRID control as management tool

Hi,
Oracle license depends on lot of things, Edition of Oracle your running standard or enterprise, the optional packges you need and etc.
Read through http://docs.oracle.com/cd/E11882_01/license.112/e10594/editions.htm#BABDJGGI
also if you license named users or processor. You can get the price for the from online oracle store

2 Node RAC with Single Node Standby Help

Hello Everyone -
I'm preparing to set up a 2 node RAC and use a single-node standby database.
I'm a bit confused on how to set up the Standby Redo Logs on the standby to use the LGWR functionality from the RAC instances.
Should I just create a set of standby redo logs (alter database add standby logfile...) like on a single-instance environment or do I need to create standby logfile threads (alter database add standby logfile thread. . . ) one for each cooresponding thread on the RAC?
It just seems odd that 2 RAC redo threads are able to write to one standby redo logfile at the same time (or maybe each RAC redo thread picks the first available standby redo log and writes to it??)
If anyone has some advice or insight, I'd appreciate it.
Andy

Hello Andy,
Did you get answer to your question about RAC with single standby?
Could you please share with me your experience if you have done so.
Thanks

Best practice for oracle 10.2 RAC with ASM

Did any one tried/installed Oracle 10.2 RAC with ASM and CRS ?
What is the best practice?
1. separate home for CRS, ASM and Oracle Database?
2. separate home for CRS and same home for ASM and Oracle Darabase?
we set up the test environment with separate CRS, ASM and Oracle database homes, but we have tons of issues with the listener, spfile and tnsnames.ora files. So, seeking advise from the gurus who implimeted/tested the same ?

I am getting ready to install the 10gR2 database software (10gR2 Clusterware was just installed ) and I want to have a home for ASM and another for database as you suggest. I have been told that 10gR2 was to have a smaller set of binaries that can be used for the ASM home ... but I am not sure how I go about installing it. The first look at the installer does not seem to make it obvious...Is it a custom build option?

Need Some Immdiate Help in Upgradation from 10.2.0.3 to 11.2.0.3 RAC 2 Nod

Hi Experts,
I want to upgrade from 10.2.0.3 to 11.2.0.3.
I have a Linux platform in place. It is a 2 NODE RAC WITH ASM
1. All my IP Addresses( Public/Private/VIP) are placed in /etc/host file.
Q1: When we upgrade to 11g It will ask for SCAN IP, what should I do for that, I don't have DNS working in my organization, where Can I get SCAN IP and its port#?
2. There are few components Invalid, Which I feel may be hindrance for my up gradation, Could you please tell me if I can upgrade the database even if Let these components Invalid?
COMP_ID COMP_NAME VERSION STATUS
AMD OLAP Catalog 10.2.0.3.0 INVALID
APS OLAP Analytic Workspace 10.2.0.3.0 INVALID
XOQ Oracle OLAP API 10.2.0.3.0 INVALID
When I checked the Invalid objects I found lot of invalid objects, tried to compile them, few got compiled rest with compilation errors, However One I found very much related to this was package body.
PACKAGE BODY OLAPSYS.DBMS_AW_UTILITIE INVALID
Tried to compile it..threw errors.
I did some R&D after checking some Oracle notes..I could find ORA-36961: Oracle OLAP is not available...poping up.

Hi,
You need to use a different IP address for the SCAN VIP. In your example, it cannot be the same as dlpqcora1.
Also, if you are not using a DNS to resolve it, then be aware that only one IP address can be configured (from note +[ID 887522.1] 11gR2 Grid Infrastructure Single Client Access Name (SCAN) Explained+ ):
>
Instead of DNS or GNS, Can we use '/etc/hosts' to resolve SCAN?
Oracle strongly recommends that you do not configure SCAN VIP addresses in the hosts file. But if you use the hosts file to resolve SCAN name, you can have only one SCAN IP address.
If hosts file is used to resolve SCAN hostname, you will receive Cluster Verification Utility failure at end of installation (See NOTE 887471.1 for more details)

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.

RAC One Node: downtime after HW-outage?

Hi ,
RAC One Node seems to be a good alternative compared to a "regular" RAC.
Since we don't have any experience with RAC One Node we are currently going through the available documentaion and try to get a picture of the advantages/disadvantages.
One major point is the question "what will exactly happen when an HW-failure or outage occurs?". It's my understanding - and what Oracle has documented - that the Oracle Clusterware provides failover protection to Oracle RAC One Node. If the node fails, Oracle Clusterware will automatically detect the failure and restart the Oracle RAC One Node database on another server in the pool.
In our case we would have the active node in Datacenter 1, the passive node in Datacenter 2. Therefore if the node in Datacenter 1 fails, the database should then get started on the node in Datacenter 2.
My questions now are:
- will that really automatically be done?
- what happens to the sessions which were connected to the database before the HW-failure?
- is it possible to determine how long this failover will take?
I'm sure that somebody has already tested this situation - any help will be appreciated.

Hi,
My questions now are:
- will that really automatically be done?Yes, automatically and transparent
- what happens to the sessions which were connected to the database before the HW-failure?Depend if you are using Omotion the connection will be redirected to another node, if you are cold failover the client will be have a short downtime.
- is it possible to determine how long this failover will take?Depend of failure, but normal (could failover) is on range from 1 to 3 minutes, using (omotion- hot failover) no downtime.
Read it :
http://www.oracle.com/technetwork/products/clustering/overview/ug-raconenode-2009-130760.pdf?ssSourceSiteId=otncn
Maybe this can clarify your issues.
Any question just ask.

Levi Pereira
Edited by: Levi Pereira on Dec 5, 2012 11:58 AM
PS: Ignore use of Omotion if you have "downtime after HW-outage". Consider only cold failover.
