Oracle Real Application Clusters

hi all
i am using oracle database 11g Release2 and Oracle Linux enterprise edition.
can anyone guide me why we need to use Oracle Real Application Clusters and plz
guide me how to install or configure all these?
and someone told me we needed 10Gb Gigabyte Ethernet.
how to go for 10GB by using LoopBack?
i am using vertualbox and i checked the loopback is only 1GB so how to go for 10GB
i posted my thread here
Oracle Real Application Clusters
but someone suggested me to for this forum so i posted here.
so if i am wrong plz forgive me.

Oracle Clusterware and Oracle Real Application Clusters Install Guide

I've downloaded the latest "Oracle Database - Oracle Clusterware and Oracle Real Application Clusters Install Guide - 10g Release 2 (10.2) for HP-UX PA-RISC" (part no. B14202-01) dated August 2005 from OTN. I'm getting the following error when opening the pdf file in Adobe Reader:
"Cannot extract the embedded font 'PEPPLC+Palatino-Italic'. Some characters may not display or print properly."
When I print the manual, I get blank pages throughout the document which, in my opinion, should contain text and don't. Specifically pages 1-11, 2-5, 2-19, 2-24, 2-33, 3-5, 3-19 to name a few. When I go to those pages within the pdf file in Adobe Reader, I get the error: "There was a problem reading this document (114)."
Can you verify this problem on your end. Also, how do I get a good copy of this document?

Converting to Oracle Real Application Clusters from Single-Instance Oracle

Is there any notes at metalink for
Converting to Oracle Real Application Clusters from Single-Instance Oracle Databases
We should have 10g DB on ASM to make it RAC?

With Oracle Database 10g Release 2, $ORACLE_HOME/bin/rconfig tool can be used to convert Single instance database to RAC. This tool takes in a xml input file and convert the Single Instance database whose information is provided in the xml. You can run this tool in "verify only" mode prior to performing actual conversion. This is documented in the RAC admin book and a sample xml can be found $ORACLE_HOME/assistants/rconfig/sampleXMLs/ConvertToRAC.xml. Grid Control 10g Release 2 provides a easy to use wizard to perform this function.

Using Tuxedo with Oracle Real Application Clusters (RAC)

Hi all ,
Our present Producation environment is Tuxedo8.0 with Oracle 9i as database .
We are planning to implement oracle RAC .
Can any one tell us , with the current tuxedo version which is 8.0 ,can we for RAC Or we need to upgrade Tuxedo to 9.1 for RAC Implementation?
If anyone has Implemented Tuxedo and Oracle with RAC successfully
Pls share your experience.
Thanks In Adavance
Nadeer .

Subbu,
As I mentioned earlier in this thread, support for Oracle RAC has been
implemented in Tuxedo 9.1 and in the Tuxedo 8.1 and Tuxedo 9.0 rolling patch
streams. There are no plans to backport this feature to Tuxedo 8.0. If you
plan to use RAC transactionally and if it is possible for multiple services
that could be located on different RAC instances to be accessed in a single
transaction (which will be true for most applications), then you should
upgrade to a version of Tuxedo with support for Oracle RAC. The
documentation at http://e-docs.bea.com/tuxedo/tux91/ads/adorac.htm#248431
gives an overview of RAC support in Tuxedo.

Hello Nadeer, Hello Ed,
Has the implementation of Tuxedo8.0 with Oracle RAC was completed
successfully ?.
If it is done , I have few doubts. Could you please help me ?.
1) I hope your Tuxedo middleware connects to the oracle Database using
Oracle XA resource manager and the TMS server built using buildtms with
oracle as RM .As per the mail from Ed, migration of Tuxedo9.1 should be done
before moving to Oracle RAC.
Also from BEA documentation, Oracle RAC support was given as new feature in
Tuxedo9.1.
Our Application uses Oracle RM to connect to Oracle DB[ Oracle 10g] from
Tuxedo8.0. So do we need to upgrade to Tuxedo9.1. for using Oracle RAC ?.
Thanks for your help

Oracle Streams & Oracle Real Application Clusters

Hello...i'am developing a new replication system to my company using Oracle Streams. I have already achieved data replication to a downstream database but now i would like to do it but in an RAC environment. So, i will appreciate any help you can give me. Best regards, walny

I've been researching but now i have another doubt, i have a cluster of five instances, two of them donwstream, one primary and one secundary, i don't now if the standby redo log files configured for the primary instance will be the same for the secundary instance, what i want to achieve is the HA of the replication environment, so if i configured standby redo log files in both instances and with just one group the problem is solved, i'll be wasting resources.
i hope you can help me
regards

Oracle Real Application Clusters Guard

Is that separate install different from RAC install ?
Is Cluster Guard is mandatory for Oracle 9i RAC environments ?

Is that separate install different from RAC install ?No. Installation of RAC RDBMS on top of cluster software should be good enough.
Is Cluster Guard is mandatory for Oracle 9i RAC environments ? RAC Guard is a part or a component of RAC, meaning if you RAC environment, it can be changed to RAC Guard environment.

How to Install 9i real application clusters on a PC!

How to install and deploy Oracle Real Application Clusters on a single Linux
server with a minimal configuration (less than $1000 worth of harware):
First of all to install Oracle cluster database you DON'T HAVE to have a cluster, but a
single PC may do as well (of course thi kind of installation will not be of
much use for a production DB). A minimal server that I HAVE TESTED is: Celeron 750 MhZ,
512 Mb of RAM, 2 IDE HD, Linux Suse 7.2
This document contains the steps needed to deploy a working Oracle 9i Database with a
minimal comment. For a complete discussion refer to Oracle documentation, namely:
Oracle 9i administrator's reference part number A90347-02
Oracle 9i Linux release notes part number A90356-01
Oracle 9i Real Application Clusters Administration part numebr A89869-01
1) set up the partitions to user for Oracle software and the ones to use as raw devices
for the cluster DB. Soppose you want to you use an HD mounted as the 3rd IDE device
(/dev/hdc) for the cluster DB. Then you have to partition it with fdisk with a large
extended partition (say hdc1). Create a large number of logical partitions inside hdc1
(say hdc5 till hdc20) of about 300 Mb in size (all of the same size for simplicity).
2) Real application clusters wants to store the DB strutures into raw devices or a
cluster filesystem. Create the raw devices using the following command (as superuser):
raw /dev/raw1 /dev/hdc5
raw /dev/raw2 /dev/hdc6 ... etc till /dev/hdc20
you will need to repeat these steps after every boot
3) Set up the Oracle user (already done with the Suse distribution), environment variables
and mount point.
Install Oracle software enterprise edition
4) Complete the installation with a custom install of the real application cluster option.
This will add a directory called oracm under your oracle home, which contains the
cluster manager software
5) edit $ORACLE_HOME/oracm/admin/nmcfg.ora, it contains 3 lines for the set-up of the
cluster manager sofware:
DefinedNodes=localhost
CmDiskFiles=/dev/raw2
CmHostName=localhost
6) edit /var/opt/oracle/srvConfig.loc. It contains 1 line with the location of a raw device
used to sync the cluster nodes:
srvconfig_loc=/dev/raw1
7) start the cluster manager software (as superuser):
$ORACLE_HOME/oracm/bin/ocmstart.sh
8) as the oracle user start the global cache service:
gsd
9) you can now create a cluster db. to use the configuration assistant you need to set
an extra environment variable:
export THREADS_FLAG=native
10) start the configuration assistant: dbca
expect some errors in the script the dbca generates, best is to review them before
execution
11) after the db creation you'll be able to start two instances on the same DB,
which means you will have a cluster DB!
12) the environment variable ORACLE_SID will determine the instance to which you can
connect by means of a special syntax: SID.parameter=value
this is used for example for paramters like instance_number, thread, etc
also the parameter cluster_database must be set to true
All these problems are normaly handled by the dbca.
Have fun,
Luca Canali
OCP-DBA

RedHat 7.1 with the some configuration I run a production 9.0.1
database: Compaq Proliant Hardware with a RA4100 storage.
The script created from the dbca seems fine, but the dbca give
me the
some error I get from:
srvconfig -init
[...]stop all daemons and oracle programs on both machines, then
start only $ORACLE_HOME/oracm/bin/ocmstart.sh,
then run the line
srvconfig -init
you can check it by running
srvconfig -version
it should output something like "9.0.0.0.0"
before running dbca, make sure ocmstart.sh and gsd are
running on both machines ("lsnodes -v" should putput sbshadow1
and dbshadow2).
BTW - I cant run clusca... Can somenome give a sample nmcfg.ora,
just to check my parameters? for dbshadow1:
DefinedNodes=dbshadow1 dbshadow2
CmDiskFiles=/dev/raw/raw2
CmHostName=dbshadow1
for dbshadow2:
DefinedNodes=dbshadow1 dbshadow2
CmDiskFiles=/dev/raw/raw2
CmHostName=dbshadow2

Ps: can you contact me by e-mail? i have some questions regarding
your HW

Required hardware for a oracle real application cluster

hello i´m a newbie and have a question:
We want to migrate a DB2 database to Oracle database. This database will run in the cluster network. What hardware do I need a prerequisite to set up an Oracle Real Application Clusters (10g)?
thank a lot for help!

Hi,
HW sizing depends on lot of information like the Size of the Database, Average load on the Database, Number of DB users, what application is using the database... could you please let us know all these information and oracle license depends on the number of CPU you on the server. Kindly let us know the OS on which you want to run the oracle RAC.
Regards,
Satya.

Oracle Real Application Testing

I'm capturing a 10.2.0.5 RAC workload and attempting to replay it on a 11.2.0.3 RAC. All the Docs describe going from a standalone node to RAC and all the steps for doing so. However, I can't find anything outlining the process from RAC to RAC.
Any help would be appreciated.
Thanks

ThanksIt's in there, you just need to look around for it (and probably do a bit of reading).
Things like
http://docs.oracle.com/cd/E11882_01/server.112/e16540/dbr_capture.htm#CACICAAC
Only one workload capture can be performed at any given time. If you have a Oracle Real Application Clusters (Oracle RAC) configuration, workload capture is performed for the entire database. To enable a clean state before starting to capture the workload, all the instances need to be restarted.
and
http://docs.oracle.com/cd/E11882_01/server.112/e16540/dbr_replay.htm#CHDBCADJ
For Oracle Real Application Clusters (Oracle RAC) databases, you can map all connection strings to a load balancing connection string. This is especially useful if the number of nodes on the replay system is different from the capture system. Alternatively, if you want to direct workload to specific instances, you can use services or explicitly specify the instance identifier in the remapped connection strings.
Cheers,

CRS 와 10G REAL APPLICATION CLUSTERS

제품 : ORACLE SERVER
작성날짜 : 2004-11-30
CRS 와 10G REAL APPLICATION CLUSTERS
===================================
PURPOSE
이 문서는, 10g Real Application Cluster의 CRS (Cluster Ready Services)에 대한 추가적인
정보를 제공하는 것을 목적으로 한다.
Explanation
1. CRS 와 10g REAL APPLICATION CLUSTERS
CRS (Cluster Ready Services)는 10g Real Application Cluster의 새로운 기능으로,
모든 플랫폼에 대해 표준화된 클러스터 인터페이스를 제공 해 주고, 이전 버전에서는 없었던
새로운 고가용 서비스를 제공해 준다.
2. CRS 핵심 기능
CRS와 10g RAC를 설치하기 전에, CRS및 10g RAC에 대해 사전에 알아 두어야 할 사항이 있다 :
- 10g RAC를 설치를 위해서는 CRS는 사전에 설치 되고 실행되어야 한다.
- CRS는 하드웨어 공급 업체에서 제공하는 클러스터 제품 (예 : Sun Cluster,
HP Serviceguard, IBM HACMP, TruCluster, Veritas Cluster, Fujitsu Primecluster,
기타 ...) 위에서 실행 될 수도 있고, 하드웨어 공급 업체에서 제공하는 클러스터 제품
없이도 실행될 수 있다. 하드웨어 업체에서 공급하는 클러스터 제품은 9i RAC까지는 반드시
필요했지만, 10g RAC에서는 선택 사항이다.
- CRS HOME 과 ORACLE_HOME 은 반드시 다른 디렉토리에 설치 되어야 한다.
- CRS를 설치하기 전에, voting 파일 또는 OCR (Oracle Configuration Repository) 파일을
설치 할 수 있는 공유된 디렉토리 또는 디바이스가 셋업되어야 한다. voting file은 최소 20MB 정도
크기이며, OCR 파일은, 최소 100MB 크기가 되어야 한다.
- CRS 및 RAC를 설치하기 위해서는 다음과 같은 네트워크 인터페이스가 구성되어야 한다 :
- Public Interface
- Private Interface
- Virtual (Public) Interface
관련된 추가적인 정보는 <Bulletin No: 22345> 참조.
- CRS 설치 후 root.sh를 실행시키면 CRS 서비스를 구동시킨다. 만약 CRS가 정상적으로
구동되지 않는다면, Note 240001.1 참조.
- RAC 노드당 1개의 CRS 데모만 실행 가능.
- 유닉스 시스템의 경우, CRS 서비스는 /etc/inittab 상의 ‘respawn’ entry로 등록되어 있다.
- 네트워크 split이 있을 경우 (노드간 통신 두절) data corruption을 방지 하기 위해 하나
또는 그 이상의 노드에서 리부팅이 발생할 수 있다.
- CRS 서비스를 구동시키는 올바른 방법은 장비를 부팅시키는 것이다.
- 서비스를 중단시키는 올바른 방법은, 장비를 shutdown 시키거나, "init.crs stop" 명령을
실행시키는 것이다.
- CRS 데몬을 kill 시키는 것은 올바른 방법이 아니며, 오직 설치된 CRS를 제거한 경우에만
적용해도 되는 방법이다. (Bulletin No: 22343 참조) 이것은 , 플래그 파일에 불일치가 발생 할
수 있기 때문이다.
- 시스템 유지 보수를 위해서는, OS를 단일 사용자 모드 (single user mode)로 전환한다.
서비스 스택이 구동되면, ps -ef 명령으로 관련된 데몬 프로세스를 확인 할 수 있다 :
[rac1]/u01/home/beta> ps -ef | grep crs
oracle 1363 999 0 11:23:21 ? 0:00 /u01/crs_home/bin/evmlogger.bin -o /u01
oracle 999 1 0 11:21:39 ? 0:01 /u01/crs_home/bin/evmd.bin
root 1003 1 0 11:21:39 ? 0:01 /u01/crs_home/bin/crsd.bin
oracle 1002 1 0 11:21:39 ? 0:01 /u01/crs_home/bin/ocssd.bin
3. CRS DAEMON 기능
다음은 각각의 CRS 데몬 프로세스에 대한 간략한 설명이다 :
CRSD:
- HA 작업을 위한 엔진
- '애플리케이션 자원'관리
- '애플리케이션 자원'을 구동, 정지, fail over 처리
- 애플리케이션 자원 구동/정지/점검 하기 위한 별도의 'actions'을 spawn
- OCR(Oracle Configuration Repository)의 구성 프로파일 관리
- OCR의 현재 알려진 상태를 저장
- root 권한으로 실행
- 장애 발생시 자동으로 재 구동됨
OCSSD:
- OCSSD는 RAC의 일부로, ASM과 함께 단일 인스턴스를 구성함
- 노드 멤버쉽에 대한 액세스를 제공
- 그룹 서비스 제공
- 기본적인 클러스터 lock 기능 제공
- 하드웨어 공급 업체에서 제공하는 클러스터 소프트웨어가 설치되어 있을 경우, 통합을 실시
- 하드웨어 공급 업체에서 제공하는 클러스터 소프트웨어 없이도 실행 가능
- 오라클 계정으로 실행
- 장애로 인한 종료시 시스템 리부팅됨
--- 리부팅은 split brain 현상 발생시, 데이터 corruption 방지를 목적으로 함.
EVMD:
- 특정한 사건 발생 시 이벤트 생성
- 자식 프로세스로 evmlogger를 spawn 시킴
- Evmlogger는 필요시 자식 프로세스를 spawn 시킴
- callout directory를 스캔하고 callout을 호출
- 오라클 계정으로 실행.
- 장애로 인한 종료시 자동으로 재 구동됨
4. CRS 로그 디렉토리
CRS 문제의 원인을 추적할 때는, CRS 홈 디렉토리 아래 디렉토리를 살펴보는 것이
중요하다.
$ORA_CRS_HOME/crs/log - 이 디렉토리는, CRS 자원들에 대한 트레이스를 포함하며,
CRS에 의해 식별된 가입(joining), 탈퇴(leaving), 재구동(restarting), 재배치(relocating)와
관련된 정보들이 기록된다.
$ORA_CRS_HOME/crs/init - crsd.bin 데몬과 관련된 모든 core dump가 기록된다.
$ORA_CRS_HOME/css/log - css 로그는, 재구성(reconfiguration)이나, 성공하지
못한 체크인 (missed checkin), 클라이언트의 css listener로 부터 발생한 연결(connect) 및
연결해제(disconnect)와 관련된 모든 액션을 기록한다. 때에 따라서는 로거에서는 (auth.crit)
유형의 메시지를 남기는데 이것은 오라클에 의해 리부팅이 발생할 때 남는다. 이 정보는
리부팅이 정확히 언제 발생했는지를 확인하는데 사용될 수 있다.
$ORA_CRS_HOME/css/init - 기본적으로는 ocssd로 부터의 core dump 파일을 저장하며, 프로세스의
종료가 심각한 문제로 간주되는 css 데몬의 pid 정보 또한 기록된다. css의 비정상 재 구동이 발생할
경우, core 파일은, core.<pid> 형태로 기록된다.
$ORA_CRS_HOME/evm/log - evn과 evmlogger 데몬의 로그 파일이 기록된다. CRS 또는 CSS 관련 디렉토리
처럼 디버깅 용도로 자주 사용되지는 않는다.
$ORA_CRS_HOME/evm/init - EVM의 pid와 lock 파일이 저장된다. EVM으로 부터 발생한 core 파일 또한
이 디렉토리에 저장된다. 디버깅을 위해서는 Note 1812.1 참조.
$ORA_CRS_HOME/srvm/log - OCR을 위한 로그 파일.
5. CRS 자원의 상태
RAC를 설치하고, RAC root.sh을 실행시키면 VIPCA (Virtual IP Configuration Assistant)가
구동된다. crs_stat 명령을 이용하여 모든 CRS 자원을 확인할 수 있다. 예 :
cd $ORA_CRS_HOME/bin
./crs_stat
NAME=ora.rac1.gsd
TYPE=application
TARGET=ONLINE
STATE=ONLINE
NAME=ora.rac1.oem
TYPE=application
TARGET=ONLINE
STATE=ONLINE
NAME=ora.rac1.ons
TYPE=application
TARGET=ONLINE
STATE=ONLINE
NAME=ora.rac1.vip
TYPE=application
TARGET=ONLINE
STATE=ONLINE
NAME=ora.rac2.gsd
TYPE=application
TARGET=ONLINE
STATE=ONLINE
NAME=ora.rac2.oem
TYPE=application
TARGET=ONLINE
STATE=ONLINE
NAME=ora.rac2.ons
TYPE=application
TARGET=ONLINE
STATE=ONLINE
NAME=ora.rac2.vip
TYPE=application
TARGET=ONLINE
STATE=ONLINE
CRS 자원을 읽기 쉬운 형태로 확인하기 위한 스크립트 또한 사용할 수 있다.
다음은 shell script의 예이다 :
--------------------------- Begin Shell Script -------------------------------
#!/usr/bin/ksh
# Sample 10g CRS resource status query script
# Description:
# - Returns formatted version of crs_stat -t, in tabular
# format, with the complete rsc names and filtering keywords
# - The argument, $RSC_KEY, is optional and if passed to the script, will
# limit the output to HA resources whose names match $RSC_KEY.
# Requirements:
# - $ORA_CRS_HOME should be set in your environment
RSC_KEY=$1
QSTAT=-u
AWK=/usr/xpg4/bin/awk # if not available use /usr/bin/awk
# Table header:echo ""

6. CRS 자원 관리
자원을 관리하기 위해서는, srvctl 명령을 사용한다. 다음은 명령어 문법 예제이다.
1) CRS 자원 상태
srvctl status database -d <database-name> [-f] [-v] [-S <level>]
srvctl status instance -d <database-name> -i <instance-name> >[,<instance-name-list>]
[-f] [-v] [-S <level>]
srvctl status service -d <database-name> -s <service-name>[,<service-name-list>]
[-f] [-v] [-S <level>]
srvctl status nodeapps [-n <node-name>]
srvctl status asm -n <node_name>
예제:
데이터베이스의 상태, 모든 인스턴스와 모든 서비스
srvctl status database -d ORACLE -v
이름이 부여된 인스턴스의 상태와 현재 서비스
srvctl status instance -d ORACLE -i RAC01, RAC02 -v
이름이 부여된 서비스의 상태.
srvctl status service -d ORACLE -s ERP -v
데이터베이스 애플리케이션을 지원하는 모든 노드의 상태.
srvctl status node
2) CRS 자원의 구동
srvctl start database -d <database-name> [-o < start-options>]
[-c <connect-string> | -q]
srvctl start instance -d <database-name> -i <instance-name>
[,<instance-name-list>] [-o <start-options>] [-c <connect-string> | -q]
srvctl start service -d <database-name> [-s <service-name>[,<service-name-list>]]
[-i <instance-name>] [-o <start-options>] [-c <connect-string> | -q]
srvctl start nodeapps -n <node-name>
srvctl start asm -n <node_name> [-i <asm_inst_name>] [-o <start_options>]
예제:
데이터베이스를 모든 활성화된 인스턴스와 함께 구동.
srvctl start database -d ORACLE
이름이 부여된 인스턴스의 구동.
srvctl start instance -d ORACLE -i RAC03, RAC04
이름이 부여된 서비스의 구동. 연관된 인스턴스는 필요시 구동됨.
srvctl start service -d ORACLE -s CRM
이름이 부여된 인스턴스의 서비스의 구동.
srvctl start service -d ORACLE -s CRM -i RAC04
노드 애플리케이션의 구동.
srvctl start nodeapps -n myclust-4
3) CRS 자원의 정지
srvctl stop database -d <database-name> [-o <stop-options>]

Real Application Clusters [upgrade] INVALID

Hi,
I was upgrading an Oracle Apps 9i database to 10g (to upgrade the 11i to R12) and when I ran the upgrade info utility, in the section Components I have ---->Real Application Clusters [upgrade] INVALID.. It is the only one with invalid.
I have no RAC, but I want to put this on RAC.
What I have to do ?
thanks,
Dana

What I have to do ?You have to do nothing :)
Since you do not have RAC, then the status column of the "Real Application Clusters" component should show 'INVALID'
but I want to put this on RACYou can do that later, once the upgrade is done.

Install Real Application Clusters (RAC) and Automated Storage Management (A

Do I have to install Real Application Clusters (RAC) and Automated Storage Management (ASM) for ETL
I have installed Oracle 10g Release 1 on WIndows 2000 with datawarehousing option.
Is it ok
Or do I need to install Oracle database again.
Please help

Greg,
From what you describe you did exactly the right thing. The runtime platform service will by default run on DWH01, but you can shut it down on that node and have it run on DWH02 (in case you wanted to bring down DWH01 but still run Warehouse Builder processes). Note that we strongly recommend using the net service name in the location registration in the deployment manager (so that you automatically take advantage of the client-side load balancing feature of RAC (as well as the server-side load balancing)).
Thanks,
Mark.

[b]Real Application Clusters[/b]

I'm doing a complex installation of Oracle9i RAC and I'm wondering if there are any books that cover Oracle9i Real Application Clusters?

Hi Terry,
Yes, there is a new Oracle9i RAC book out, by Mike Ault.
I think it is far better than the documentation. You can get it at this link:
