Issues while installing ORACLE 10g R2 RAC on RHEL 5.3

i am installing oracle 10g R2 RAC on RHEL 5.3 in a test environment. my aim was to install using ASM.
i went through the pre-requisites ok before beginning with the installation.
since RHEL 5.3 doesnt support raw devices i used

did you check this
http://download-west.oracle.com/docs/cd/B19306_01/install.102/b14203/storage.htm#BABBHECD
http://download.oracle.com/docs/cd/B28359_01/install.111/b28263/storage.htm#CDEBFDEH
also before you do what is suggested on the url posted by Mufalani,
it seems that you should do the following:
Check existence of udev raw mapping rule file /etc/udev/rules.d/60-raw.rules
On RH/EL5, udev raw mapping rule file /etc/udev/rules.d/60-raw.rules should exist by default as part of the util-linux package, for example:
# ls /etc/udev/rules.d/60-raw.rules
/etc/udev/rules.d/60-raw.rulesCreate a custom udev raw mapping rule file, /etc/udev/rules.d/61-oracleraw.rules say, for example:
# touch /etc/udev/rules.d/61-oracleraw.rules3b. Add udev raw binding rules to /etc/udev/rules.d/61-oracleraw.rules file
Add the udev raw binding rules to the /etc/udev/rules.d/61-oracleraw.rules file, for example:
# cat /etc/udev/rules.d/61-oracleraw.rules
# Raw bind to Oracle Clusterware devices

Note, the script does not factor device name persistency.
#!/bin/bash
grep -v "^ *#" /etc/sysconfig/rawdevices | grep -v "^$" | while read dev major minor ; do

How to upgade Oracle from 9.2 on SUN to Oracle 10g R2 RAC on Oracle EL4

Hi all,
I have production database Oracle 9i EE Release 9.2.0.5.0 - 64bit on SunOS 5.9 cca 100GB. I would like to upgrade Oracle 10g Relase2 RAC with 2 nodes on Oracle Enterprise Linux. Database availability is 24x7 and system breakdown must be minimal. Upgrade could be done in several independent steps. What is the best form of upgrade realisation?
Thx for some idea
Libor Veverka
[email protected]

My 2 cents:
1. de-RAC 9i on solaris
2. upgrade to 10g on solaris (why? take advantage of datapump, much faster than exp/imp)
3. expdp from 10g solaris
4. create single instance 10g on linux
5. impdp on linux
Please note there are a number of issues with 9ir2.10gr2 upgrade (check metalink for details).
HTH,

Oracle 10g SEO replication to Oracle 10g EE RAC

Hi!!!
I have 200 nodes with Oracle 10g Standard Edition One and a DataCenter with 3 nodes Oracle 10g Enterprise Edition Real Application Clusters. My questions is, how to replicate data from each node to datacenter with the objective to centralize all data.
The database structure is the same in all nodes, and there is no conflict.
My real problem is Oracle Standard Edition One, it's not support advanced replication like Streams and Materialized Views, and i cant use other version of oracle because it´s huge money.
Please any advice?
Thanks in advance.

I'm more of an Oracle developer than a DBA, and I'm not sure this is feasible, but it sounds like you are in dire need of an idea, so here it is. Take the transaction logs from your 200 nodes, copy them to your central site (at whatever time interval you require), and peform a "restore" to the central server using those logs, even though they did not come from the central server.

Oracle 10g R2 RAC - IP address Change

We succsessfully installed Oracle 10gR2 single database on two node RAC on Windows 2003. I followed the Oracle RAC installation documentation and assigned a public IP for the machine and another Virtual Public IP and a Private IP. We have also changed the "hosts" file in Windows to reflect the above mentioned confiuration. Here is a snippet of the "hosts" file in Windows.
xxx.xxx.xx.xxx NODE1
xxx.xxx.xx.xxx NODE1-VIP
192.168.1.161 NODE1-PRIV
xxx.xxx.xx.xxx NODE2
xxx.xxx.xx.xxx NODE2-VIP
192.168.1.161 NODE2-PRIV
After succsessful installation and testing for a few days, we are in a situation where we need to chanage the public IP's for NODE1-VIP and NODE2-VIP. If I change the IP's in the "hosts" file for NODE1-VIP and NODE2-VIP and restart the computer, both the nodes are not starting up and it comes back with a windows error. But If I change back to the old IP's, it works absolutely fine. How can we change the Virtual IP's associated for each node after a successful RAC installation?
Thanks.

Hi,
The VIP are registered as a highly available resource within the Oracle Cluster Registry (OCR).
If you want to use different VIP's than the previously configured you need this Metalink Note: 271121.1 - How to change VIP and VIP/Hostname in 10g
Be aware of the following bug: 4500688 - THE INTERFACE NAME SHOULD BE SPECIFY WHEN EXECUTING 'SRVCTL MODIFY NODEAPPS' that is not described in the mentioned Metalink note above. This means that it is better idea to modify the VIPs by explicitly specifying the network interface name, for instance: srvctl modify nodeapps -n mynode1 -A 100.200.300.40/255.255.255.0/eth0

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 10g with RAC option

What is the requirement for Dell machine, Intel Linux for the configuration for RAC on Oracle Standard Edition?

in 9i RAC runs with Enterprise Option and I think in 10g must run in Enterprise Option with more reasons than before.

1.) For some reason I cannot get the mappings to work correctly, I have rebooted the server and tried a number of different changes in the rules script. But for the life of me I cannot get it work.
I noticed when I rebooted the server that it failed to execute the iscsidev. When I manually run the shell script with a parameter it produces output
Can anyone help me to get this up and running?
2.) My QNAP Nas doesnt seem to publish iSCSI targets to only one NIC. I think this is down to the firmware/feature not being available. When I discover targets I get the following

VIP for Oracle 10g R2 RAC

Hi All,
I have a doubt, We are installing 10g R2 2-node RAC on RHEL4 U4. Can we have same IP address for VIP for both the nodes?
Thanks,
Praveen.

Thanks for the response..
Ok, i'll have unique IP addresses for VIP.

Experiences with Oracle 10g/11g RAC on VMWare Fusion for Macbook and OEL 5

Folks,
I recently purchased a new Macbook Pro laptop computer to use for demos and testing with Oracle RAC. I am using VMWare Fusion for Mac OS X to setup new VM machines with Oracle 11g.
Thus far, I can setup single instance Oracle 11g database fine with OEL 5 (32 bit OS) as the guest OS. The problem that I keep running into due to the limitation with VMWare Fusion product is that I am not able to edit the VMWare network settings to allow multiple VM machines to communicate with each other. The second main issue that I currently face is that VMWare Fusion does not allow you to setup shared disks which are a requirement to install and configure an Oracle RAC environment. I came to the realization that after searching forums online that
one must setup a third VM machine to act as an NFS or iSCSI filer system to present to the other VM hosts for the shared storage requirement for RAC. Has anyone been able to do all
of this successfully with VMWare Fusion on a Macbook ? If so, I would definitely be interested in finding out how you did this. Specifically the following:
1. Network configuration for each VMWare Fusion guest OS machine
2. Shared storage ie) NFS or OpenFiler VM machine
Regards,
Ben

Oracle 10g RAC on 2 VMware Windows 2003 images corrupts image

It happened twice on each of the 2 VMware workstation 5 on which I am trying to set up an Oracle 10g R2 RAC. After installing CRS and rebooting machine I lost access to the Network Connections and the Disk Management. Basically I have to create a new image. Before I start a third time I would appreciate advice or feedback from other users.
Also Configuration Assistants failed to install.
Thanks

Check out my articles at http://dbasupport.com on 10g R2 RAC Clusterware setup. I was able to do that on my vmware BUT I hope to have the very irritating ASM scenario done before my 4th Article.
Check it out.

Oracle 10g RAC: misscount value

Hi,
On an Oracle 10g R2 RAC environment for Linux 4.5, I noticed that misscount value returned by crsctl is different from its value in $CRS_HOME/install/rootconfig. Is that acceptable?
By the way, misscount value had been modified manually by the DBA who insalled the RAC database during installation in $CRS_HOME/install/rootconfig file but he didn't use the crsctl set command.
Should we still modify it using crsctl set command as well?
[oracle@rac1 bin]$ crsctl get css misscount
60
[oracle@rac1 bin]$ cat /u01/crs/install/rootconfig | grep misscount
CLSCFG_MISCNT="-misscount 300"

MISSCOUNT is for network heartbeat between nodes. Please find out the reason why it is set to 60 currently. Current effective value is 60s. This value will be overridden with value in rootconfig file if DBA run root.sh. At this stage, find out why it is set to 60 for your knowledge and information.

Oracle 10g RAC Database Migration from SAN to New SAN.

Hi All,
Our client has implemented a Two Node Oracle 10g R2 RAC on HP-UX v2. The Database is on ASM and on HP EVA 4000 SAN. The database size in around 1.2 TB.
Now the requirement is to migrate the Database and Clusterware files to a New SAN (EVA 6400).
SAN to SAN migration can't be done as the customer didn't get license for such storage migration.
My immediate suggestion was to connect the New SAN and present the LUNs and add the Disks from New SAN and wait for rebalance to complete. Then drop the Old Disks which are on Old SAN. Exact Steps To Migrate ASM Diskgroups To Another SAN Without Downtime. (Doc ID 837308.1).
Clients wants us to suggest alternate solutions as they are worried that presenting LUNs from Old SAN and New SAN at the same time may give some issues and also if re-balance fails then it may affect the database. Also they are not able to estimate the time to re-balance a 1.2 TB database across Disks from 2 different SAN. Downtime window is ony 48 hours.
One wild suggestion was to:
1. Connect the New SAN.
2. Create New Diskgroups on New SAN from Oracle RAC env.
3. Backup the Production database and restore on the same Oracle RAC servers but on New Diskgroups.
4. Start the database from new Diskgroup location by updating the spfile/pfile
5. Make sure everything is fine then drop the current Diskgroups from Old SAN.
Will the above idea work in Production env? I think there is a lot of risks in doing the above.
Customer does not have Oracle RAC on Test env so there isn't any chance of trying out any method.
Any suggestion is appreciated.
Rgds,
Thiru.

Downtime window is ony 48 hours.Adding and removing LUNs online is one of the great features of ASM. The Rebalance will be perfomed under SAN. No downtime!!!
If your customer is not entrusting on ASM. So Oracle Support can answer all doubt.
Any concern .. Contat Oracle Support to guide you in the best way to perform this work.

ASM Supports many Terabytes, if you need to migrate 3 Database with 20TB each using this way described above would be very laborious .. .. So add and remove Luns online is one feature that must work.
Take the approval from Oracle support and do this work using the ASM Rebalance.

How to create a new ASM Diskgroup in Oracle 10g RAC?

Hi,
Our env is Oracle 10g R2 RAC on HP-UX. I want to create a new ASM Diskgroup. Please let me know if the following steps are ok to create a new ASM Diskgroup.
1. Ensure the new Disk is visible in both ASM instances in RAC (v$asm_disk) and the header_status is 'CANDIDATE'
2. From Node 1 ASM Instance issue the create diskgroup command.
SQL> create diskgroup DATA2 external redundancy disk '/dev/rdsk/c4t0d5';
3. Query v$asm_diskgroup and make sure the Diskgroup is created.
4. Mount the DATA2 Diskgroup from Node 2 ASM Instance.
5. Query v$asm_diskgroup and make sure the Diskgroup is visible from Node2 ASM instance.
6. Ensure the header_status is 'MEMBER'.
Rgds,

correct.
instead of using device file '/dev/rdsk/c4t0d5' you can create an alternate device file using mknod, which is called "asm_disk_xg" for example.
