Changing oracle_home(standalone to ORACLE RAC).

Customer has two oracle environments on the same envioronments.
1) Standalone database running on Standalone oracle_home.
2) RAC databases running on RAC ORACLE_HOME.
Now customer would like to change standalone database to RAC ORACLE_HOME. What is the procedure for this.
Oracle version is 11.2.0.3.4 on both environments. Just i need to change the oracle_home only. If any additional clarifications...happy to reply with more details....
Thanks in-advance.

Single-Instance Database on a Cluster Running from an Oracle RAC-Disabled Home
You can create a single-instance database on a cluster running from an Oracle home with the Oracle RAC option disabled. To create an Oracle home on a cluster with Oracle RAC disabled, you can select local and non-cluster on the Node Selection Page of Oracle Universal Installer when installing the Oracle Database software. You can also performed a one-node cluster (with Oracle RAC) installation, but later disable the Oracle RAC option.
Perform the following procedures to convert this type of single-instance database to an Oracle RAC or Oracle RAC One Node database:
1.    Use DBCA to create a preconfigured image of your single-instance database as described in "Use DBCA to Create an Image of the Single-Instance Database" To perform the conversion manually, shut down the single-instance database.
2.    Change the directory to the lib subdirectory in the rdbms directory under the Oracle home.
3.    Relink the oracle binary by running the following commands:
4. make -f ins_rdbms.mk rac_on
5. make -f ins_rdbms.mk ioracle

Adding Standalone listener Oracle RAC

Dear Experts
We have oracle RAC setup on in our organization, now we also need to do streaming between our RAC server and another oracle server for public reports. We installed another network interface card on of our Oracle RAC server and connect it directly to other server but we are not able to add listener for that interfaces. I did manually entered listener configuration in "listener.ora" and added it also in CRS using "srvctl add listener". Srvctl start listener properly but when i check the status of listener using "lsnrctl status <listener_name> than it shows that listener do not support any services.
Your help will really be appreciate.

Dear P
Thanks for prompt reply. My listener for RAC is working fine, but standalone listener for one node on specific interface is not working. However i have added the listener using "srvctl add listener" command and it also start successfully but it does not support any service. See below the output of lsnrctl status.

Database replication between Oracle RAC and Oracle Standalone DB in 9i

Hi,
We have currently 4 node RAC environment and Oracle RAC implementation with 4 Oracle instances. We want to move the one instance and make it Standalone with Oracle database due to availability issue. Thus we will remain with 3 nodes on the RAC database and one Standalone database. We want to implement Oracle replication on this solution, where partial database of RAC environment needs to be replicated to Standalone node.
We will have Oracle 9i database server for both RAC and Standalone machine.
The partial data that we are looking for replication are of size 25GB. Some of questions we have:
1. Is there any other replication mechanism apart from Materilzed view for this solution?
2. Is it feasible to sychronize around 25GB data between servers?
3. What can be estimated time for refresh or Synchronization?
The methods that we are evaluating currently for this replication are:
1. Multi Master replication
2. Oracle 9i Datagaurd.
Please let me know if we need to look for some other methods of replication also.
Thanks in advance for help.

2. Is it feasible to sychronize around 25GB data between servers?Sure. Depending on the rate of change, your latency requirements, whether the standalone database has the horsepower to apply all the changes generated by to other three nodes, etc.
3. What can be estimated time for refresh or Synchronization?Depends on the architecture, the network connection, whether you are doing incremental refreshes, etc. And it depends on what time you're measuring-- you might be measuring the latency between the RAC cluster and the standalone database, you might be measuring the time it takes to incrementally refresh a single materailized view when there have been no changes, you might be measuring the time it takes to do a complete refresh of an entire refresh group, pulling 25 GB of data over the network.
The methods that we are evaluating currently for this replication are:
1. Multi Master replication
2. Oracle 9i Datagaurd.DataGuard is not an option if you only want to replicate a subset of the data. The two realistic options are materialized views and Streams. Are you anticipating that you will be making changes on both nodes? If not, you can use simple materialized views rather than multi-master replication.
Since 9.2 is not longer covered by Premier Support, are you planning to upgrade to a supported version in the near future? In particular, Streams works a lot better in later versions of the database.

ORACLE_HOME in Oracle RAC 11g (Windows Server 2008)

Hello,
I've got two (2) nodes in an Oracle RAC 11g in Windows Server 2008. Oracle software is installed in C:\app.
I realized that it's not been set ORACLE_HOME path. In System Properties-> Advanced -> Environment Variables, I see that ORACLE_HOME is empty.
- Which path would be the ORACLE_HOME: C:\app\bd\product\11.2.0\dbhome_1
- Do you have to setup the same in both nodes?
Thanks

I realized that it's not been set ORACLE_HOME path. In System Properties-> Advanced -> Environment Variables, I see that ORACLE_HOME is empty.its normal behaviour
- Which path would be the ORACLE_HOME: C:\app\bd\product\11.2.0\dbhome_1if you installed that location, yes
- Do you have to setup the same in both nodes?actually, you dont HAVE TO, its not needed at all

Oracle RAC server's IP and Subnetmask change

Oracle DB Version:10.2.0.3.0
OS version : RedHat linux 4
Number of Nodes: 2
We need to move our RAC db servers from Atlanta to NJ. This move requires IP and subnet mask change. How we can do this chanse in for nodeapps / CRS components?

I am doing a clean installation of RAC 10g rev.2, and during the installation I set the netmask for the VIP to 255.255.252.0, which is different from the pub netmask of 255.255.255.0.
I ran the following:
srvctl modify nodeapps -n rachost1 -A 192.168.180.88/255.255.255.0/pub
srvctl modify nodeapps -n rachost2 -A 192.168.180.89/255.255.255.0/pub
I then stopped the services.

Trying to change Oracle listener port 1521 to nodefault port on Oracle RAC

Could somebody please help me in the process of changing teh Oracle listener port 1521 to a non-default port on an Oracle RAC environment. I am total of four instance.
Regards.

Please read carefully about LOCAL_LISTENER parameter, you shouldn't put there just hostname....
Another way to do so - statically register database SID in listener. You should do it in listener.ora file, please read carefully documentation, otherwise you can use netca utility - it could make configuration for you properly.

Manual creation of Oracle RAC Database

Hello Guru's,
I successfully installed Oracle Grid(clusterware) and Oracle RDBMS 11.2.0.1.0 for RAC containing 2 nodes on Linux 5.3 64 bit.
All the clusterware services and ASM instance are running fine on both nodes.
Now im planning to create database manually on node1 (RAC-NODE1).
1) configure the environmental variables as follows
export TMP=/tmp
export ORACLE_HOSTNAME=`hostname`
export ORACLE_SID=finance1
export ORACLE_UNQNAME=finance
export ORACLE_BASE=/rdbms1/app/oracle/
export ORACLE_HOME=/rdbms1/app/oracle/product/11.2.0/db_home/
export ORACLE_TERM=xterm
export PATH=$ORACLE_HOME/bin:$PATH:.
export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib
export CLASSPATH=$ORACLE_HOME/JRE:$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib
2) created the pfile and modified the parameters as follows
db_name='finance'
processes = 200
audit_trail ='db'
db_block_size=8192
db_domain='vod.com'
diagnostic_dest='/oradump/oradata/finance/dump'
sessions=200
remote_login_passwordfile='EXCLUSIVE'
undo_tablespace='UNDOTBS1'
control_files = +CTRL
compatible ='11.2.0'
job_queue_processes = 10
undo_management = 'AUTO'
finance1.instance_name = finance1
db_create_file_dest = +DBFILE
db_create_online_log_dest_1 = +REDO1
db_create_online_log_dest_2 = +REDO2
3) Created the password file as follows
$ orapwd file=orapwfinance1 passwors=syspassword entries=10
4) edit the /etc/oratab file as follows
finance1:/rdbms1/app/oracle/product/11.2.0/db_home:N
5) created the rac db script as follows.
CREATE DATABASE FINANCE
DATAFILE '+DBFILE' SIZE 500M

I know this problem is coming for improper assiging of permissions, but i could not pin point. kindly clarify the same.
one more thing i need to know.., whenever i rebooted nodes, both of raw devices and asm disks are come to default permission brw------, i have to change every time to brw-rw-r--. is there any way to make these disks and devices permissions make permenet.
Thanks in advance.

Recommendations - Oracle RAC 10g on Solaris 10 Containers Logical/Local..

Dear Oracle Experts et all
I have a couple of questions for Oracle 10g RAC implementation on Solaris and seek your advice. we are attempting to implement oracle 10g RAC on Solaris OS and SPARC Platform.
1 We are wondering if Oracle 10g RAC could be implemented on Solaris Local/Logical Containers? I was assuming that Oracle will always link it self with OS binaries and Libraries while S/W installation and hence will need an OS image/Root Disk over which it could go. However, in containers, I assume we have a single solaris installation and configuration which will thus be shared to the containers which will be further configured in it. In such situations how does Oracle instalation proceed? Do I need to look at a scenario where, the global Container/Zone will have Oracle install and this image be shared across to zones/containers accordingly? If it is so, what all filesystems from OS will need to be shared across to these zones/containers?
Additionally, even if this approach is supported, is it a recommended approach? I am unsure about the stability and functionality of Oracle in such cases and am not able to completly conceptualize. However, I assume there could be certain items which needs to be approprietly taken care off. It will help if you could share observations from your experiences.
2 The idea of RAC we are looking at is to have multiple Oracle Installations on top of native clustering solution say veritas clusters/Sun Clusters. Do we still need to have Oracle Cluster solution Clusterware (ORACRS) on top of this to achieve Oracle Clustering? Will I be able to install Oracle as a standalone installation on top of native clustering solution say veritas clusters/Sun Clusters?
Our requirement is to have the above mentioned multiple Oracle installations spread across two (2) seperate H/W platforms,say Node A and Node B, and configure our Cluster Solution to behave as active-passive across Node A and Node B. In other words, I will configure Clustering Solution like VRTS/SunCluster in Active-Passive, then have 3 Oracle installations on Node A, another 3 on Node B. I will configure one database each for each of these Oracle S/W installation (with an idea not to have Clusterware between clustering solution VRTS/SunCluster and Oracle installation, if it works). Now I will run 3 databases thus on each of these nodes. If any downtime happens on any one of the nodes, say Node A, I will fail all oracle databases and S/W accordingly to the alternate available node, Node B in this case, using native clustering solution and I will want the database to behave as it was behaving earlier, on Node A. I am not sure though if I will be able to bring the database up on Node B when resources in OS perspective are failed over.
we want to use Oracle 10g RAC Release 2 EE on Solaris 10 OS latest/one before the latest release.
Please share your thoughts.
Regards!

1 We are wondering if Oracle 10g RAC could be implemented on Solaris Local/Logical Containers? My understanding is that RAC in a Zone (Container) is not supported by Oracle, and will not work anyway. Regardless of installation, RAC needs to do cluster level stuff about the cluster configuration, changing network addresses dynamically, and sending guaranteed messages over the cluster interconnect. None of this stuff can be done in a Local Zone in Solaris, because Local Zones have fewer permissions that the Global Zone. This is part of the design of Solaris Zones, and nothing to do with how Oracle RAC itself works on them.
This is all down to the security model of Zones, and Local Zones lack the ability to do certain things, to stop them reconfiguring themselves and impacting other Zones. Hence RAC cannot do dynamic cluster reconfiguration in a Local Zone, such as changing virtual network addresses when a node fails.
My understanding is that RAC just cannot work in a Local Zone. This was certainly true 5 years ago (mid 2005), and was a result of the inherent design and implementation of Zones in Solaris. Things may have changed, so check the Solaris documentation, and check if Oracle RAC is supported in Local Zones. However, as I said, this limitation was inherent in the design of Zones, so I do not see how Sun could possibly have changed it so that RAC would work in a Local Zone.
To me, your only option is the Global Zone. Which pretty much destroys the argument for having Zones on a Solaris system, unless you can host other non-Oracle application on the other Zones.
2 The idea of RAC we are looking at is to have multiple Oracle Installations on top of native clustering solution say veritas clusters/Sun Clusters. Do we still need to have Oracle Cluster solution Clusterware (ORACRS) on top of this to achieve Oracle Clustering? Will I be able to install Oracle as a standalone installation on top of native clustering solution say veritas clusters/Sun Clusters?I am not sure the term 'native' is correct. All 'Cluster' software is low level, and has components that run within the operating system. Whether this is Sun Cluster, Veritas Cluster Server, or Oracle Clusterware. They are all as 'native' to Solaris as each other. They all perform the same function for Oracle RAC around Cluster management - which nodes are members of the cluster, heartbeats between nodes, reliable fast message delivery, etc.
You only need one piece of Cluster software. So pick one and use it. If you use the Sun or Veritas cluster products, then you do not need the Oracle Clusterware software. But I would use it, because it is free (included with RAC), is from Oracle themselves and so guaranteed to work, is fully supported, and is one less third party product to deal with. Having an all Oracle software stack makes things simpler and more reliable, as far as I am concerned. You can be sure that Oracle will have fully tested RAC on their own Clusterware, and be able to replicate any issues in their own support environments.
Officially the Sun and Veritas products will work and are supported. But when you get a problem with your Cluster environment, who are you going to call? You really want to avoid "finger pointing" when you have a problem, with each vendor blaming the cause of the problem on another vendor. Using an all Oracle stack is simpler, and ensures Oracle will "own" all your support problems.
Also future upgrades between versions will be simpler, as Oracle will release all their software together, and have tested it together. When using third party Cluster software, you have to wait for all vendors to release new versions of their own software, and then wait again while it is tested against all the different third party software that runs on it. I have heard of customers stuck on old versions of certain cluster products, who cannot upgrade because there are no compatible combinations in the support matrices between the cluster product and Oracle database versions.
I will configure Clustering Solution like VRTS/SunCluster in Active-Passive, then have 3 Oracle installations on Node A, another 3 on Node B. As I said before, these 3 Oracle installations will actually all be on the same Global Zone, because RAC will not go into Local Zones.

/u01/app/oracle/product/11.2.0/dbhome_1/bin/rman target sys/viviet@vvsms log /home/oracle/log_rman/vvsms.log appendThis line can be your problem.
As this database is a RAC and your are using a service with load balance "vvsms" and "/home/oracle/backup/vvsms" is not a shared location. RMAN is starting a session on Other node where "/home/oracle/backup/vvsms" does not exists.
Try change it :
/u01/app/oracle/product/11.2.0/dbhome_1/bin/rman target sys/viviet@vvsms log /home/oracle/log_rman/vvsms.log appendTo this (using Easy Connect Method):
/u01/app/oracle/product/11.2.0/dbhome_1/bin/rman target sys/viviet@localhost:1521/VVSMS log /home/oracle/log_rman/vvsms.log appendWhere:
localhost: your local node
VVSMS : is the service of database
Also check if "/u01/app/oracle/product/11.2.0/dbhome_1/network/admin/sqlnet.ora" have configured the line "NAMES.DIRECTORY_PATH= (TNSNAMES, EZCONNECT)"
P.S : When RMAN start a session it show where is logged, check on logs what instance RMAN was logged.

Oracle Rac 11.2.0.3 doubts

Hi experts,
Current system info:
server 1 with Redhat 6.5 and Orale ASM with SAP ECC 6 GRID 11.2.0.3 standalone installation
Target system info:
Server 1 and server 2 running RAC 11.2.0.3 with SAP ECC 6 and RedHat 6.5 GRID with cluster
We are trying to convert our current system to oracle RAC but have some doubts.
We are following "Configuration of SAP NetWeaver for Oracle Grid Infrastructure 11.2.0.2 and Oracle Real Application Clusters 11g Release 2: A Best Practices Guide" so:
On page 29 It says: "Prepare the storage location for storing the shared ORACLE_HOME directory in the cluster. The Oracle RDBMS software should be installed into an empty directory, accessible from all nodes in the cluster" Same thing for ORACLE_BASE for the RDBMS, SAP subdirectories (sapbackup, sapcheck, sapreorg, saptrace, oraarch etc.) and homedirectories for SAP users ora<SID> and <SID>adm to a shared filesystem.
1.-Can we just use NFS for sharing them? or what is the recommended software on REDHAT for doing it?
'cause on note 527843 it says:
You must store the following components in a shared file system (cluster, NFS, or ACFS) here it says we can, but down the note on section linux says:
RAC 11.2.0.3/4 (x86 & x86_64 only):
Oracle Clusterware 11.2.0.3/4 + ASM/ACFS 11.2.0.3/4 (Oracle Linux 5, Oracle Linux 6, RHEL 5, RHEL 6, SLES 10, SLES 11)
Oracle Clusterware 11.2.0.3/4 + NetApp NFS or
Oracle Clusterware 11.2.0.3/4 + EMC Celerra NFS
It does not mention just NFS.
2.-In our system test, we want to backup all oracle configuration files on file systems and then delete Oracle Grid to Install GRID with cluster option, then install RDBMS with rac option and then follow the guide, is that correct?
Regards

Hi Ramon,
1.-Can we just use NFS for sharing them? or what is the recommended software on REDHAT for doing it?
'cause on note 527843 it says:

Oracle Clusterware 11.2.0.3/4 + ASM/ACFS 11.2.0.3/4 (Oracle Linux 5, Oracle Linux 6, RHEL 5, RHEL 6, SLES 10, SLES 11)
Oracle Clusterware 11.2.0.3/4 + NetApp NFS or
Oracle Clusterware 11.2.0.3/4 + EMC Celerra NFS
It does not mention just NFS.
NFS mount as suggest in SAP documentation should work. The use of ACFS always requires a special Oracle Grid Infrastructure (GI) Patch Set Update (PSU). Oracle Support Note 1369107.1 contains details about which GI PSU is required when you use ACFS with a specific RHEL update, service pack from SLES or UEK version of Oracle.
2.-In our system test, we want to backup all oracle configuration files on file systems and then delete Oracle Grid to Install GRID with cluster option, then install RDBMS with rac option and then follow the guide, is that correct?
You may perform DB backup using backup tools and then scrap the existing Grid setup. Configure RAC and then restore the backup into the new configuraiton as per SAP guidelines under
Configuration of SAP NetWeaver for Oracle Grid Infrastructure 11.2 with Oracle Real Application Clusters 11g Release 2
Hope this helps.

Solaris x86 with Oracle RAC 10g Enterprise Edition Release 10.2.0.3.0

Hello,
Maybe you can help me (new on RMAN backup) in doing this.
I have configured a single Oracle 10g database to have backup with RMAN with following steps:
1. $ mkdir $ORACLE_BASE/rman_scripts
2. $ mkdir $ORACLE_BASE/logs
3. $ mkdir $ORACLE_BASE/tracking
4. $ mkdir $ORACLE_BASE/c_backup
5. $ sqlplus sys/<password> as sysdba
6. SQL> alter system set db_recovery_file_dest_size = 50G scope=both;
7. SQL> alter system set db_recovery_file_dest='${ ORACLE_BASE}/flash_recovery_ area' scope=both;
8. SQL> alter system set log_archive_dest_10='location= use_db_recovery_file_dest';
9. SQL> shutdown immediate
10. SQL> startup nomount
11. SQL> alter database archivelog;
12. SQL> alter database open;
13. SQL> alter database enable block change tracking using file '${ORACLE_BASE}/tracking/rman_ change_track.f';
14. $ rman target /
15. RMAN> CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK

16. RMAN> CONFIGURE CONTROLFILE AUTOBACKUP ON;
17. RMAN> CONFIGURE BACKUP OPTIMIZATION ON;
18. RMAN> CONFIGURE RETENTION POLICY TO RECOVERY WINDOW OF 7 DAYS;
19. RMAN> exit
I need to configure incremental backup with RMAN on a two node Solaris x86 with Oracle RAC 10g Enterprise Edition Release 10.2.0.3.0 installation.
We also use ASM to store database files, and have Oracle software installed on separate file systems (two Oracle roots for Node1 and Node2).
I have following questions:
1) where to put Flash Recovery Area (FRA)?
I saw recommendations to put FRA on the ASM, is this the best way to do it?
2) Can I put FRA on another file system (not on the ASM) which is available only from Node1? This way I can save space on the ASM.
3) Is it possible/recommended to run RMAN from Node1 only?
Below is the script used to run RMAN on the normal Oracle database (without RAC) which I need to change :
=============================================================================================
2.0 Oracle backup script: /opt/app/oracle/rman_scripts/backup.sh
Use this for daily backups, possiblly as a cron job.
Once a week run this: /opt/app/oracle/rman_scripts/backup.sh FULL
All other days of the week: /opt/app/oracle/rman_scripts/backup.sh INCREMENTAL
Note: You may have to change ORACLE_SID, ORACLE_BASE below to match your database.
=============================================================================================
#!/usr/bin/ksh
ORACLE_SID=orcl
ORACLE_BASE=/opt/app/oracle
ORACLE_HOME=${ORACLE_BASE}/product/10.2.0/db_1
PATH=${ORACLE_HOME}/bin:/usr/bin
LOGDIR=${ORACLE_BASE}/logs
LOGFILE=${LOGDIR}/rman.log
if [[ $# < 1 ]]
then
echo "usage: backup.sh FULL|INCREMENTAL"
exit;
fi
BACKUPTYPE=${1}
full='FULL'
incremental='INCREMENTAL'
if [[ $BACKUPTYPE == $full ]]
then
$ORACLE_HOME/bin/rman target / nocatalog log ${LOGFILE} append << eof
run {
backup database;
SQL 'alter system archive log current';
backup archivelog all;
delete noprompt obsolete;
exit;

if [[ $BACKUPTYPE == $incremental ]]
then
$ORACLE_HOME/bin/rman target / nocatalog log ${LOGFILE} append << eof
run {
backup database;
backup incremental level 1 database;
SQL 'alter system archive log current';
backup archivelog all;
delete noprompt obsolete;
exit;
eof
echo ''
fi

Hi [email protected],
Q1) where to put Flash Recovery Area (FRA)?
A1) With RAC: on the shared storage
I saw recommendations to put FRA on the ASM, is this the best way to do it?
If you want your backups to be available for both nodes you have to use shared storage or tape using an mml library.
So if you want to use the FRA for rman backups and the database is on ASM just make ASM the standard for the FRA as well.
Q2) Can I put FRA on another file system (not on the ASM) which is available only from Node1? This way I can save space on the ASM.
A2) Than you cannot recover in case Node1 is down. Best would be to send your storage admin to a training course so he can manage the clustered raw devices needed for ASM.
Q3) Is it possible/recommended to run RMAN from Node1 only?
A3) No see A2.

Tycho

CRS10g patchset을 적용한 이후 Veritas SF Oracle RAC 관련 MODULE

Problem Description
다음은 SF(Storage Foundation) Oracle RAC를 구성하기 위하여 Oracle CRS
PATCHSET 등을 적용하기 전에 SF Oracle RAC Veritas libraries 를 ORACLE_HOME에 설치해야 한다는 내용입니다.
또한, ORACLE CRS 패치 Version 을 올리면서 Veritas 쪽 관련하여 필요한
Veritas skgxp module 등이 설치 과정에 빠져 있거나 Veritas library file들이 overwrite되어 에러를 만나는 경우를 볼 수 있습니다.
이런 관점에서 Veritas storage foundation 을 설치하고 oracle CRS stack을
설치 또는 갱신하는 과정에서 만날 수 있는 에러에 대해 원인 및 해결방안을 알아봅니다.
에러 증상
다음은 CRS 10.2.0.3.0 Patchset이 설치되면서 Veritas library가 overwrite 되면서 발생하는 에러임.
Veritas clusterware 5.0 not recognized by Oracle due to the fact that Veritas libraries over written with crs 10.2.0.3.0 patchset installation.

OS : Solaris Operating System (SPARC 64-bit)
이 예제는 sun os에 근거함.
OS에 따라 해결책이 약간 다를 수는 있습니다.
원인
새로운 CRS patch 관련 변경이 있은 이후에 Veritas SFRAC 관련 module이 인식되지 못하는 문제 야기됨.
Installing and Configuring SF Oracle RAC Software
Veritas 에서 제공하는 Storage/Clusterware 관련한 절차는 이 문서에서 생략합니다.
Install CD 안의 installsfrac 스크립트 수행 session 에서 RAC software installation을 하는 과정이 들어갑니다.
Veritas가 제공하는 SF Oracle RAC 5.0 installation 문서를 보면 다음과 같은 내용이 포함되어 있습니다.
아래 내용에는 SF Oracle RAC component 들을 설치하는 과정만 기술합니다.
# cd /cdrom/storage_foundation_for_oracle_rac
# .installsfrac -configure
Note: Do not run root.sh yet, but return to the installsfrac session from step 15.
19 In the installsfrac session, press Return. The installsfrac utility now verifies
the database software installation, copies the SF Oracle RAC libraries to $ORACLE_HOME, and relinks Oracle on each node in the cluster.
다음은 위와 같은 installsfrac 스크립트를 수행한 이후에 Installer가 5.0 SF Oracle RAC library file들을 ORACLE_HOME으로 Copy하는 과정이고, Oracle library file들을 relink합니다.
자세한 절차는 다음의 site에서 step 별로 확인을 할 수 있습니다.

방법2. Relinking Oracle10g (Installer)
위 Article에서 Relinking Oracle 10g after upgrading SF Oracle RAC 부분을 참조하여 해결하는 것도 가능합니다.
여기서 2개의 node name이 galaxy 와 nebula 라고 가정합니다.
1. Invoke installsfrac once again:
# cd /opt/VRTS/install
#./installsfrac -configure
2. Enter the system names when prompted:
Enter the system names separated by spaces on which to configure
SFRAC: galaxy nebula
3. Navigate to the "Install and Relink Oracle" menu.
a. Select the appropriate Oracle 10g version (3):
1) Oracle 10gR1
2) Oracle 10gR2
b. Select "Relink Oracle" (3) from the menu:
1) Install Oracle Clusterware (CRS)
2) Install Oracle RDBMS server
3) Relink Oracle
b) [Go to previous menu]
c. From the menu displayed, enter the required information. For example:
Enter Oracle UNIX user name: (oracle) oracle
Enter Oracle UNIX group name: [b] (oinstall) oinstall
Enter Oracle base directory: [b] /app/oracle
Enter absolute path of CRS Home directory: [b] /app/crshome
Enter absolute path of Database Home directory: [b] /app/oracle/orahome
Enter Oracle Bits (64/32) [b] (64) 64
d. Confirm your responses in the verification screen. The installer copies the SF 5.0 Oracle RAC libraries to /opt/ORCLcluster, where it expects libskgxn.
Oracle environment information verification
Oracle Unix User: oracle
Oracle Unix Group: oinstall
Oracle Clusterware (CRS) Home: /app/crshome
Oracle Release: 10.2
Oracle Bits: 64
Oracle Base: /app/oracle
Oracle Home: /app/oracle/orahome

e. Enter "q" at the next prompt to leave the installer now that CRS setup
tasks are complete.
4. Bring the CSSD resource online. Enter:
# hares -online cssd -sys galaxy
# hares -online cssd -sys nebula
5. Confirm that CRS in online. Enter:
$CRS_HOME/bin/crs_stat -t
6. Bring online the oracle resources configured under VCS. If they're directly controlled by CRS, you may run the CRS commands to start the instance.
[ 참고 ]
CRS patch 적용 이후에 HP server와 Veritas 환경에서 CRS stack 이 올라오지
않는 경우를 추가 설명해 봅니다.
참고로, Veritas 쪽에서 Node status를 check해 주는 tool을 제공하고 있고,
CRS의 init.cssd 에서 그 tool을 사용하도록 init.cssd 에 patch가 되어야 한
다는 내용의 문서가 있습니다.
그 작업을 위한 patch를 역시 Veritas에서 제공하고 있습니다.
CRS patchset 이나 CRS 를 위한 cumulative patch를 하기 전에 SFRAC 를 위해
init.cssd에 patch를 적용해야 합니다.
Symptoms
1. postrootpatch.sh hangs when apply a patch[set]
2. prerootpatch.sh hangs when rollback a patch[set]

Pack 1
on HP-UX 11iv2 and cross references to product documentation
환경
Veritas on HP server
이 patch 는 HP-UX 11i 에만 해당함.
예방책
Before you run the root.sh script, you need to add the init.cssd.patch.
a. Open another window on the system where you are running the installer
b. Log in as superuser
c. Change to the directory where the patch is to be copied:
For Oracle 10gR1:
# cd $CRS_HOME/css/admin
# cp /opt/VRTSvcs/rac/patch /init.cssd-10gR1.patch .
For Oracle 10gR2:
# cd $CRS_HOME/css/admin
# cp /opt/VRTSvcs/rac/patch /init.cssd-10gR2.patch .
d. Run the following command to install the patch:
For Oracle 10gR1:
# patch < init.cssd-10gR1.patch init.cssd
For Oracle 10gR2:
# patch < init.cssd-10gR2.patch init.cssd
e. Run the root.sh script. For example:
# cd $CRS_HOME
# ./root.sh
This starts the CRS daemons on the node where you enter the command.
