10g RAC nic drivers re-install

We running 10g (10.2.0.3) 2 node rac cluster on win 2003 and we had some issue on network card drivers. System administrator wants to uninstall all nic card drivers and re-install with new version and ip configuration & setting remains same as eariler.
After re-install of new drivers, the new registry & nic guid change will cause any problem to oracle cluster setting?
Appreciate your replies.

As far as the basic network settings (interface name, ip address, subnet etc..) doesn't change, you should be ok. We have replaced NIC cards in the linux environment and haven't seen any problems - unless Oracle stores the GUID in the windows world (which I really doubt).

Oracle 10G RAC - Public & Heartbeat on 1 NIC

Hello all,
actually I am installing Oracle 10G RAC on rhel 4 (4 node cluster). But the Cluster Verification Utility aborts with errors. I checked the configToolAllCommands and tried to run the failed commands manually:
#/opt/oracle/crs/bin/oifcfg setif -global eth0.100/172.18.0.0:cluster_interconnect eth0.728/172.16.128.0:public eth0.498/172.17.1.0:cluster_interconnect
PRIF-50: duplicate interface is given in the input
PRIF-50: duplicate interface is given in the input

Question:
Is it possible to put Public & Heartbeat on one NIC (eth0.728 & eth0.498)
If not is their any workaround for that issue?

Hi all,
I have a question about Oracle RAC and network interface.
We're using Oracle 10gR2 RAC with two nodes on Linux Red Hat.
Let's assume that the public network interface goes down.
I would like to know what happens with existing connections
on node with network interface with problems.
Are connections frozen, actives?
Can the users continue to use theses existing connections using the another node of RAC?If the interface is down? what do you think? All connections to this node will die. How does your application handle fail-over, does it attempt to reconnect or just have a complete application failure?
You should spend some time in a test lab where you can test this stuff for yourself. Read the documentation and there are tons of sites out there that purport to have all of your RAC/TAF/FAN/FAF questions. - I would read and trust the documentation first.

I know that the listener goes down and any other connections is allowed.
Thank you very much!!!!

MULTIPLE USERS 10G RAC ORACLE_HOME INSTALL WITH ASM/CRS

Hi,
We need to install multiple 10g RAC databases on a two node Sun servers. Below is our configuration:
1) Sun Solaris (ver 10) with Sun Cluster 3.2
2) One ASM/CRS install (by 1 OS account)
3) Four ORACLE_HOME 10g database install (by 4 different OS user accounts)
We would like to use one ASM instance for all four databases with appropriate privileges.
OS User:           OS Group
========      =========
oraasm           dbaasm - (ASM and CRS install owner)
ora1           dbaora1 - first db owner
ora2           dbaora2 - second db owner
ora3           dbaora3 - third db owner
ora4           dbaora4 - fourth db owner
I understand that certain privileges need to be shared between ASM/CRS and DB owners. Please let me know the steps to be followed to complete this install.
Thanks in advance.

Hi
Please read that: Documentation http://download.oracle.com/docs/html/B10766_08/intro.htm
- You can install and operate multiple Oracle homes and different versions of Oracle cluster database software on the same computer as described in the following points:
-You can install multiple Oracle Database 10g RAC homes on the same node. The multiple homes feature enables you to install one or more releases on the same machine in multiple Oracle home directories. However, each node can have only one CRS home.
-In addition, you cannot install Oracle Database 10g RAC into an existing single-instance Oracle home. If you have an Oracle home for Oracle Database 10g, then use a different Oracle home, and one that is available across the entire cluster for your new installation. Similarly, if you have an Oracle home for an earlier Oracle cluster database software release, then you must also use a different home for the new installation.
If the OUI detects an earlier version of a database, then the OUI asks you about your upgrade preferences. You have the option to upgrade one of the previous-version databases with DBUA or to create a new database using DBCA. The information collected during this dialog is passed to DBUA or DBCA after the software is installed.
- You can use the OUI to complete some of the de-install and re-install steps for Oracle Database 10g Real Application Clusters if needed.
Note:
Do not move Oracle binaries from one Oracle home to another because this causes dynamic link failures.
. If you are using ASM with Oracle database instances from multiple database homes on the same node, then Oracle recommends that you run the ASM instance from an Oracle home that is distinct from the database homes. In addition, the ASM home should be installed on every cluster node. This prevents the accidental removal of ASM instances that are in use by databases from other homes during the de-installation of a database's Oracle home.

Oracle-10g RAC on VMware installed on Windows-7(Host)

Hi,
My host OS is Windows-7. Docs. posted on this forum for RAC on VMware says: your Host OS should be Centos OS and in which you will install VMware and Client tools also. In this way u can clone another RAC2 machine.
But I have Oracle VM Virtual Box installed on Windows-7. Another is VMware Player installed on Windows-7.
I want to install Oracle-10g RAC on my Laptop. Please any suggestions or Docs. related to this.

Is there a way to use different NIC names in 10g RAC?

For example node 1 has ipge0 for private, ipge1 for private and node 2 has Solaris default e1000g0 and e1000g1? Or do interface names have to match on all nodes? I am not referring to IPs or subnets - just NIC names.
Here is some background.
This was a 2 node 10g RAC on Solaris that has been in operation for years. Node 2 experienced a corrupt root partition (OS, nothing to do with Oracle), so OS was reinstalled. After OS reinstall I copied /var/opt/oracle/*.* from node 1, changed them to reflect node 2 info, plus CRS related files from /etc/init.d, such as init.crsd, etc. This is shared Oracle home, so Oracle continued to run on node 1 just fine.
However, after crs startup nodeapps tells me "atlts04ra.atlts04.vip:ifconfig: status: SIOCGLIFFLAGS: ipge0: no such interface". Indeed, this interface does not exist on node 2.
So, is there a way to instruct oracle to use different interface names for nodes? Or will vipca ask for matching NIC names just like disk mount names have to match?
I want to avoid reinstallation of RAC because that will disrupt oracle database that has been running on shared oracle home all along.
Thanks.

Fzheng, I am very interested in your statement "however you can change the e1000g0 to ipge0".
You mean to say there is an OS script that will downgrade ipge0 interfaces to e1000g0?
I got some more information from SysAdmins yesterday. Apparently, when OS was reinstalled on node 2 after root partition corruption, they also patched it up to Solaris 10u9 (which by default created e1000g0-type interfaces). The first node still had 10u7 with ipge0 interfaces. We, the DBAs, were not aware of the upgrade. So, nodeapps cant start saying "no such interface"on node 2.
You are probably referring to script /usr/sbin/e1000g_transition.
Here is the description:
"DESCRIPTION
This script allows you to perform an optional driver upgrade
for the Intel PRO/1000 device present on this system from the \"ipge\"
network driver to the Sun standard \"e1000g\" network driver. The
e1000g driver include features such as link aggregation as well as
superior performance in most environments. Moving forward, e1000g
will benefit from new features as they become available, bug fixes,
and performance enhancements. The disadvantage is that some
applications configuration files may require modification to use
e1000g if they reference the ipge network interface.
This script must be run in single user mode.
This script will alter network interfaces and related system
configuration files. Configuration files for 3rd party applications
will NOT be changed. After running this script, applications present
on the system may require maintenance. The system may be in an
unsecured state. The effects of this script may be reversed using
the backout (-b) option."
So, if I understand you correctly, you are proposing to run this this script with the backout (-b) option on node 2, so interface names will match.
Is this correct?
Thanks.
Vladimir Grigorian.

NIC ROUTER requirement for 10g RAC database

I need to know what hardware to order in setting up an 10g RAC database without a single-point-of-failure. My question centers on the networks. If each server has one NIC for the public interface and one NIC for the private interconnect, aren't the routers these NICs are attached to a single point of failure? If each server has two NICs bonded together for the public interface and two NICs bonded together for the private interconnect, does each NIC attach to a different router?

is RDMA and infiband ar same??Infiniband is a switched fabric layer for high speed communication. RDMA is a protocol for "+remote direct memory access+".
Infiniband supports the Internet Protocol suite over Infiniband, or IPoIB. It also supports RDMA over Infiniband.
so do we need only infiband SDR / QDR switch to set infiband OR what else??You need an Infiniband switch - Cisco and Voltaire are two companies that supply this type of hardware. The latter is used by Oracle in its Exadata database machines. Unsure about Cisco's commitment to Infiniband switches as they have discontinued their Infiniband switches with integrated fibre channel gateways. A sore point with us after we bought into this technology about 2 years ago, in part on their very own recommendations - and now own very expensive, somewhat buggy and totally unsupported hardware. Seems like the new Cisco California servers are GigE and not Infiniband, which perhaps explain this (flawed) decision of theirs...
For each cluster node, you need an Infiniband PCI card (typically has 2 ports). If you are going to use bonding, you will need a pair of Infiniband cables per server. Also remember to get spares - both PCI cards and cables.
If you want redundancy at the switch, you need to get yourself 2 Infiniband switches.
But if you're planning to invest this into a RAC cluster, then surely you should also invest money in RAC licensing and support - and with that gain access to very useful documentation like the RAC Starter Kit and so on.

Metalink Note 239998.1 tells you how to tidy things up after installation and deinstallation problems

Oracle Database 10g - RAC install

1)
I am trying to install Oracle 10g RAC (for Solaris Operating System (SPARC)) using 'Enterprise/Standard Edition for Solaris Operating System (SPARC, 64-bit) - ship_rel10_sol64_db.cpio.gz' downloaded installation. There is no separate installation for RAC, so I assume this is the right install to use for RAC, right?
Since I don't have cabeling for Interconnect done yet, I tried to install Database/RAC prior CRS installation, but no option has been offered for RAC. Do I need to have clustering software installed first in order to be able to installl Oracle Database RAC?
2)
Why is Oracle Database 10g release 10.1.0.3 patch set (for Solaris Operating System (SPARC)) so large - 648 MB?
Do I need to install 10.1.0.2 first?

Hello,
there's no extra RAC software package, but the option is only offered, if one of the supported cluster layers for the respective OS has been installed before.
10.1.0.3 looks like a complete redesign, but anyway it is a patch, you have to install 10.1.0.2 first.

Oracle database not starting up in oracle 10g RAC

Hi!
Recently I came across one problem with one node oracle 10g RAC.When the Oracle database is started,while opening it is giving ORA-03113:End of file on communication channel error.When I saw the the alert trace file and other trace files I found Disk group is exhausted error and it is not able to create .dbf files.Actually it is not a production server and I gave archive log destination in SAN.Even the spfile(content of init_database.ora) is in SAN..
I tried Asmcmd utility to delete the archive log files.As the oracle is not available I am not able to asmcmd prompt.
How to change the destination of archive log and to remove the old archive log files(as it is a testing environment we can remove) from SAN?Please let me know.
Thanks & Regards

On VMware there's a known issue with Oracle databases on a Windows client not starting up properly all the time and a manual startup using oradim -start -sid <whatever> is required to get it fully running. Hmmm, doing it several time, and never seen such issue. Which "known issue" and by who are you talking about ?
I created a brand new Oracle VM Windows 2003 32-bit server, installed the Oracle drivers for paravirtualization, and whammo, the problem is still hereI'm sure, you miss something somewhere in the config. Right now, you're on supported configuration, you could either raise a SR to the support, or get help from your peer on Oracle Database General forum.
Ah, but it's not a Windows issue. On a non-VM Windows box the database starts just fine all the time. Again, this is a known issue acknowledged by Oracle on the VMware side, I'm just surprised it exists on the Oracle VM side.Again, give more details about this "known issue". Never heard about that, eventhough I've been around for years.
I was afraid you were going to ask that. I'll have to search for it again, but I think you can do the same as well....Well, I doubt you could find a Metalink note about Oracle on VMWare. So far, Oracle has always refused to support database on OS virtualized on VMWare (or any VM software other than Oracle VM). Based on that, you could be sure, your "known issue" is not an issue on Oracle VM.
If you want more help, again, give more details about your issue.

Seeking a solid reccomendation concerning 10g RAC implementation.

I need a solid recommendation regarding what hardware I should use for my planned Oracle 10g RAC environment.
Currently, I am looking for both node and SAN recommendations.
I also created a list of 11 questions that I need to have answered.
Here is how this will be configured:
3 Node Oracle 10g RAC
Each Node will consist of:
32Gb of RAM (minimum)
Windows 2003 64-bit Enterprise (corporate standard, but I can go with Windows 2008 if I have a valid justification)
74Gb RAID 1 (minimum)
Dual 10Gb Ethernet NICs
The SAN will consist of:
750Gb-3Tb dedicated to Oracle
10Gb Ethernet NICs
Here are some of my general questions:
1.) Are there any benchmarks or case studies that you are aware of that might help in the decision process regarding hardware?
2.) Where should my backups reside (SAN or elsewhere)?
3.) What margin should be added for SAN provisioning and waste (even if thin provisioning is implemented)?
4.) My CIO has decided to direct me to go with 10GbE copper instead of fiber channel, what unplanned hiccups can I expect?
5.) What are the caveats of running dual redundant SAN systems?
6.) We are currently using DELL hardware for all other systems, however I do have the freedom to change the vendor for this particular project if I can state a valid business justification. Any other vendors out there that make a better SAN or Node solution than Dell/EMC?
7.) How much local storage do I need on each node?
8.) Can I utilize 1 node to run ETL during production hours without drastically affecting database performance?
9.) Regarding the maintenance of this setup, are their any particular classes or training you would recommend? I am a seasoned Oracle DBA, but could use any specific training on the specifics of RAC and/or general performance.
10.) Are there specific advantages in Oracle 11g RAC vs. 10g that would be worth the cost of upgrading our 1000+ 10g user licenses?
11.) Are there any studies on the performance advantages/disadvantages of running Oracle 10g on Windows vs. Solaris (or any Unix)?
I will consider all input of high value, so please let me know what you would recommend.
Thank you for your time.

please find answers that i know for some questions.
1.) Are there any benchmarks or case studies that you are aware of that might help in the decision process regarding hardware?
2.) Where should my backups reside (SAN or elsewhere)?
=> what is the backup method you will be using? certainly recommend RMAN (in addition to OS backups that you are planning to use) for block recovery, should there a block corruption.
i would keep some copies on the SAN local and mirror to DR site too.
3.) What margin should be added for SAN provisioning and waste (even if thin provisioning is implemented)?
=> do not suggest thin provisioning for production.
how big the volumes are going to be? reason for asking the Q is, if the volumes are going to be in TB, percentages can be lower. please plan for 2 years atleast.
4.) My CIO has decided to direct me to go with 10GbE copper instead of fiber channel, what unplanned hiccups can I expect?
5.) What are the caveats of running dual redundant SAN systems?
6.) We are currently using DELL hardware for all other systems, however I do have the freedom to change the vendor for this particular project if I can state a valid business justification. Any other vendors out there that make a better SAN or Node solution than Dell/EMC?
7.) How much local storage do I need on each node?
=> have beetween 75GB to 100GB. hope you are going to have only ORACLE RDBMS and CRS software in here.
please make sure that you rotate your listener logs and alert logs and regular removal of old .trc files older than certain number of days old.
8.) Can I utilize 1 node to run ETL during production hours without drastically affecting database performance?
=> node usage will help from CPU standpoint only. what about the disk writes it is going to perform to the data files?
9.) Regarding the maintenance of this setup, are their any particular classes or training you would recommend? I am a seasoned Oracle DBA, but could use any specific training on the specifics of RAC and/or general performance.
=> attend a 5 day course from Oracle. install RAC on own and play with it.
10.) Are there specific advantages in Oracle 11g RAC vs. 10g that would be worth the cost of upgrading our 1000+ 10g user licenses?
=> did not compare, though installed 11g.
11.) Are there any studies on the performance advantages/disadvantages of running Oracle 10g on Windows vs. Solaris (or any Unix)?
=> running on windows? please do not. used on linux a lot. pretty stable and solid. recommend to go with 10.2.0.4 or higher.
hope the above will help.
