Installation of oracle 10g rac on open solaris for X86 Machine

Hi
Can you please let me know the advantages of installation of oracle 10g rac on open solaris on x86 machine.And also let me know the detail steps involved in instatllation of oracle 10g rac on open solaris on x86. please suggest the recommdendation for the installation
Thanks
Saiprasath

If by "advantages of installation of oracle 10g rac on open solaris on x86 machine" you mean advantages over RAC on Linux or AIX or HP/UX there aren't any.
If you want to know the advantages of RAC over stand-alone they generally relate to:
1. Eliminating the server as a single point of failure
2. Transparent fail-over
2. Incremental horizontal scalability

Regarding Hangcheck timer configuration in Oracle RAC 10g r2 installation

Hi,
Is it necessary to configure hangcheck timer in Oracle RAC 10g R2 installation .
Can somebody guide when we should install the hangcheck timer in Linux oracle 10g R2.
Best Regards
Gupteswar Prasad Mishra
Edited by: Gupteswar on Jan 25, 2010 8:42 PM

yes, its recommended to configure hangcheck timer in RAC configuration
Configure the Hangcheck Timer
The hang-check timer is loaded into the Linux kernel and checks if the system hangs. It will set a timer and check the timer after a certain amount of time. There is a configurable threshold to hang-check that, if exceeded will reboot the machine. Although the hangcheck-timer module is not required for Oracle Clusterware (Cluster Manager) operation, it is highly recommended by Oracle.
cat /etc/rc.local
modprobe hangcheck-timer hangcheck_tick=1 hangcheck_margin=10 hangcheck_reboot=1

I had this problem and resolved it by transporting the file to the installation server with the correct ftp datatype (binary).
On page 54 of the install guide (..Server\Oracle_Business_Intelligence\doc\doc\bi.1013\b31765.pdf) that comes with the installation files, there is an instruction to make sure that any ftp activity is done in binary.
This may not have occured with the license.xml file if you use a tool which offers the "feature" of automatic datatype recognition.
Hope this helps.

Hi,
don't worry about GSD. GSD is only used if you also run 9i databases in the cluster. Even though it should state as OFFLINE (not as unknown), I would not care about that.
However ONS should not be in the status UNKNOWN.
Can you do the following:
srvctl start nodeapps -n
To restart the ONS and see if it stays.
Also post the output on onsctl debug
(All from CRS Home).

Question about RAC 10g on server running AIX and domain name changes

We have several 10g clusters running on IBM p-Series AIX servers, and our company is changing the domain name for our network. I am concerned that if we do not change the domain names in the TNSNAMES.ora file and also the /etc/hosts file on each server, the cluster will no longer function. We are using CRS (version 10.2.0.3) and ASM within each cluster.
Does anyone know where I can find information about changing the domain name that was set up as part of the CRS and database installs for RAC? Does anyone have experience doing this, and would be willing to share a few insights? Thanks in advance for any advice you can give!

You may be able to use the VIPCA utility for RAC to change or modify the public and private settings for your domain names on AIX. Also, the Oracle 10g DBCA "Database Configuration Assistant" should be of use to change your settings for your RAC environment.
Also, see here for a good IBM Redbook that covers Oracle 10g RAC on AIX platforms:

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
TO '/var/opt/oracle/flash_ recovery_area/ORCL/c_backup/% F';
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;
eof
echo ''
fi
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

Which file decide instance name in RAC 10g ?

Which file decide instance name in RAC 10g ?
How does RAC know which instance should start from which machine?
Thanks.

The spfile is NOT the correct answer, actually.
1. The instance name for any Oracle instance, whether in a RAC or not, is derived from the value for the ORACLE_SID parameter which is in force at the time the startup command is issued. If you were to:
export ORACLE_SID=SALES
sqlplus / as sysdba
startup...you would just have created an instance called SALES.
2. The spfile (or init.ora if you're not using an spfile) contains a parameter called INSTANCE_NAME. That defaults to whatever ORACLE_SID is set to as an environment variable when the instance is started, hence point 1 above. But you can force an instance to acquire a non-SID name by deliberately setting it to something different. That's unusual to do, though, except in a RAC context where you want to subvert the default load balancing mechanism.
2b. The spfile (or init.ora) also contains a parameter called DB_NAME -but that is the name of the database, not the name of the instance, and is therefore irrelevant for the purposes of working out how instances get their names,
3. Neither of the above answers has got anything to do with RAC knowing what instance runs on which machine. That is the job of the Oracle Cluster Registry file (OCR), for which you have to provide about 100MB of space on a shared hard drive during the RAC installation itself.
You populate that file by running DBCA to create your RAC instances (and DBCA then automatically updates the OCR to record the fact that it created instance X1 on Node A and X2 on Node B, and therefore that's what will happen in the future unless you change things).
Or you can update the OCR yourself by using the SRVCTL utility. You'd do something like: srvctl add instance -d DB1 -i X3 -n C (add an instance called X3 to run on Node C as part of database DB1).
A little more details about the OCR is available in Section 13 of this article, for example: http://www.dizwell.com/prod/node/26?page=0%2C5

Problem of using OCFS2 as shared storage to install RAC 10g on VMware

Hi, all
I am installing a RAC 10g cluster with two linux nodes on VMware. I created a shared 5G disk for the two nodes as shared storage partition. By using OCFS2 tools, i formatted this shared storage partition and successfully auto mounted it on both nodes.
Before installing, i use the command "runcluvfy.sh stage -pre crsinst -n node1,node2" to determine the installation prerequisites. Everything is ok except an error "Could not find a suitable set of interfaces for VIPs.". By searching the web, i found this error could be safely ignored.
The OCFS2 works well on both nodes, i formatted the shared partition as ocfs2 file system and configure o2bc to auto start ocfs service. I mounted the shared disk on both nodes at /ocfs directory. By adding an entry into both nodes' /etc/fstab, this partition can be auto mounted at system boots. I could access files in shared partition on both nodes.
My problem is that, when installing clusterware, at the stage "Specify Oracle Cluster Registry", I enter "/ocfs/OCRFILE" for Specify OCR Location and "/ocfs/OCRFILE_Mirror" for Specify OCR Mirror Location. But got an error as following:
----- Error Message ----
The location /ocfs/OCRFILE, entered for the Oracle Cluster Registry(OCR) is not shared across all the nodes in the cluster. Specify a shared raw partition or cluster file system that is visible by the same name on all nodes of the cluster.
------ Error Message ---
I don't know why the OUI can't recognize /ocfs as shared partition. On both nodes, using command "mounted.ocfs2 -f", i can get the result:
Device FS Nodes
/dev/sdb1 ocfs2 node1, node2
What's the possible wrong? Any help is appreciated!
Addition information:
1) uname -r
2.6.9-42.0.0.0.1.EL
2) Permission of shared partition
$ls -ld /ocfs/
drwxrwxr-x 6 oracle dba 4096 Aug 3 18:22 /ocfs/

Hello
I am not sure how far this following solution is relevant to your problem (regardless when it was originally posted - may help someone who is reading this thread), here is what I faced and here is how I fixed it:
I was setting up RAC using VMWare. I prepared rac1 [installed OS, configured disks, users, etc] and the made a copy of it as rac2. So far so good. When, as per the guide I was following for RAC configuration, I started OCFS2 configuration, faced the following error on RAC2 when I tried to mount the /dev/adb1:
===================================================
[Root @ *rac2* ~] # mount - t ocfs2 - o datavolume, nointr / dev / sdb1 / ocfs
ocfs2_hb_ctl: OCFS2 DIRECTORY corrupted WHILE reading uuid ocfs2_hb_ctl: OCFS2 DIRECTORY corrupted WHILE reading uuid
mount.ocfs2: Error WHEN attempting TO run / sbin / ocfs2_hb_ctl: "Operation not permitted" mount.ocfs2: Error WHEN attempting TO run / sbin / ocfs2_hb_ctl: "Operation not permitted"
===================================================
After a lot of "googling around", I finally bumped into a page, the kind person who posted the solution said [in my words below and more detailed ]:
o shutdown both rac1 and rac2
o in VMWare, "edit virtual machine settings" for rac1
o remove the disk [make sure you drop the correct one]
o recreate it and select *"allocate all disk space now"* [with same name and in the same directory where it was before]
o start rac1 and login as *"root"* and *"fdisk /dev/sdb"* [or whichever is/was your disk where you r installing ocfs2]
Once done, repeat the steps for configuring OCFS2. I was successfully able to mount the disk on both machines.
All this problem was apparently caused by not choosing "allocate all disk space now" option while creating the disk to be used for OCFS2.
If you still have any questions or problem, email me at [email protected] and I'll try to get back to you at my earliest.
Good luck!
