Adding Box for Oracle RAC(Clustering) to BIW 3.5 Oracle/Linus

Hai Gurus,
Suppose if we have 1 box with Bw3.5 Linux/Oracle and add another box to do Oracle RAC(clustring). Do we need to re-instal the Box 1 also or we can do that with small configuration changes.
Guide me.
Regards,
Mano

Hi Mano
As in most cases there is a short answer and a longer one. Short:
If your system is RAC ready, switching from single instance to cluster database and adding a new node is quite simple. From pure application side there will not be major changes necessary.
Long:
What do i need for oracle RAC, what do i have to do to make my system RAC ready?
Hardware / OS
You will need shared disks, cluster fs, on linux mostly OCFS2. If you don't have it yet, you need to get it and move your database on to it. You would probably need an additional lan interface for the interconnect.
Oracle / Database
You would have to install CRS, that is the oracle cluster software. Your oracle instance, listener will run as services controlled by CRS when RAC is enabled. You will need to configure separate redo threads and undo tablespaces for each node you add. Not least you would probably need an additional costly RAC extension license from your favorite oracle sales rep.
SAP
You should think about separate enqueue server and enqueue replication, although this is not mandatory. This is dependent on your reasons for using RAC. If it is high availability you should go for it.
This is not a complete list, i just wanted to give you an initial idea, please ask if you need further details. If you start into RAC just now, you will have a long way to go, otherwise the short answer will apply.
Best regards
Michael

About Oracle RAC-CLUSTERS-HTMLDB-APLICATION SERVER

Im trying to learn about Oracle RAC and its integration with others Oracle tools and have some questions that I want to know .
1º) I undertand that a Oracle Cluster are vaious computers that store a extensive Database.
2º) I also understand that a RAC are various computers that keep instances of a ORACLE database, and this database can be store on a CLUSTER.
Now my questions:
Can I have others computers with ORACLE TOOLS, by example, HTMLDB ,to serve web pages with information store in that CLUSTER, or ORACLE APPLICATION SERVER, to serve ORACLE FORMS AND REPORTS by example, also with information store in that . taking information from the instances of database working in the RACś Computer?
By Example Can I have 5 computers , every one with a diferent tool, 3 with htmldb and 2 with aplication server, taking information from one computer of RAC, that have a instances of this database working?
Regards everybody

2º) I also understand that a RAC are various computers that keep instances of a ORACLE database, and this database can be store on a CLUSTER.
Not quite ...
Each part in a RAC IS AN INSTANCE, and each instance controls the same database as all the other instances.
Therefore, HTMLDB, which is simply kept in a database, can be delivererd to the users from any instance, or from all, in the RAC.
FORMS and REPORTS can connect to any instance in the RAC and get exactly the same data from exactly the same database as when connecting to any other instance in the RAC.
Therefore, in a RAC, you do not have different instances 'with different tools'. An external-to-database tool, such as forms, points to one olf the instances. An internal-to-database tool, such as htmldb, is available through all of the instances.

Oracle Upgrade from Oracle RAC 9.2.0.6 to Oracle 10.2.0.4

Hi All,
Currently, we are running 4 node Oracle RAC environment with below mentioned configuration.
OS: Sun Solaris 5.9
Hardware: Sun E2900
Oracle Version: 9.2.0.6
Veritas Cluster Server: 4.1
We want to upgrade Oracle version to 10g, and currently analyzing the options to perform this. The current database size is 1TB appx and we want to spend minimum application shutdown time running on this database.
As part of upgrade, we also need to upgrade Veritas Cluster Server from 4.1 to 5.1 to support Oracle 10g. It would be great help,, if someone can pass some guideline to perform this task.
We are currently thinking about piecemeal approach, where we can upgrade each node individually and then put them back to cluster. There are some complexities involved, and its really high risk approach.
Thanks a lot in advance for help
Regards,
Manoj

Orcale 10g RAC requires you to install Oracle Clusterware. Oracle Supports running it along side a 3rd party clustering software. Not sure why you're so anxious to upgrade Veritas Clusterware when it will be trivial on the 10g db hosts.

Oracle RAC Interconnect, PowerVM VLANs, and the Limit of 20

Hello,
Our company has a requirement to build a multitude of Oracle RAC clusters on AIX using Power VM on 770s and 795 hardware.
We presently have 802.1q trunking configured on our Virtual I/O Servers, and have currently consumed 12 of 20 allowed VLANs for a virtual ethernet adapter. We have read the Oracle RAC FAQ on Oracle Metalink and it seems to otherwise discourage the use of sharing these interconnect VLANs between different clusters. This puts us in a scalability bind; IBM limits VLANs to 20 and Oracle says there is a one-to-one relationship between VLANs and subnets and RAC clusters. We must assume we have a fixed number of network interfaces available and that we absolutely have to leverage virtualized network hardware in order to build these environments. "add more network adapters to VIO" isn't an acceptable solution for us.
Does anyone know if Oracle can afford any flexibility which would allow us to host multiple Oracle RAC interconnects on the same 802.1q trunk VLAN? We will independently guarantee the bandwidth, latency, and redundancy requirements are met for proper Oracle RAC performance, however we don't want a design "flaw" to cause us supportability issues in the future.
We'd like it very much if we could have a bunch of two-node clusters all sharing the same private interconnect. For example:
Cluster 1, node 1: 192.168.16.2 / 255.255.255.0 / VLAN 16
Cluster 1, node 2: 192.168.16.3 / 255.255.255.0 / VLAN 16
Cluster 2, node 1: 192.168.16.4 / 255.255.255.0 / VLAN 16
Cluster 2, node 2: 192.168.16.5 / 255.255.255.0 / VLAN 16
Cluster 3, node 1: 192.168.16.6 / 255.255.255.0 / VLAN 16
Cluster 3, node 2: 192.168.16.7 / 255.255.255.0 / VLAN 16
Cluster 4, node 1: 192.168.16.8 / 255.255.255.0 / VLAN 16
Cluster 4, node 2: 192.168.16.9 / 255.255.255.0 / VLAN 16
etc.
Whereas the concern is that Oracle Corp will only support us if we do this:
Cluster 1, node 1: 192.168.16.2 / 255.255.255.0 / VLAN 16
Cluster 1, node 2: 192.168.16.3 / 255.255.255.0 / VLAN 16
Cluster 2, node 1: 192.168.17.2 / 255.255.255.0 / VLAN 17
Cluster 2, node 2: 192.168.17.3 / 255.255.255.0 / VLAN 17
Cluster 3, node 1: 192.168.18.2 / 255.255.255.0 / VLAN 18
Cluster 3, node 2: 192.168.18.3 / 255.255.255.0 / VLAN 18
Cluster 4, node 1: 192.168.19.2 / 255.255.255.0 / VLAN 19
Cluster 4, node 2: 192.168.19.3 / 255.255.255.0 / VLAN 19
Which eats one VLAN per RAC cluster.

Thank you for your answer!!
I think I roughly understand the argument behind a 2-node RAC and a 3-node or greater RAC. We, unfortunately, were provided with two physical pieces of hardware to virtualize to support production (and two more to support non-production) and as a result we really have no place to host a third RAC node without placing it within the same "failure domain" (I hate that term) as one of the other nodes.
My role is primarily as a system engineer, and, generally speaking, our main goals are eliminating single points of failure. We may be misusing 2-node RACs to eliminate single points of failure since it seems to violate the real intentions behind RAC, which is used more appropriately to scale wide to many nodes. Unfortunately, we've scaled out to only two nodes, and opted to scale these two nodes up, making them huge with many CPUs and lots of memory.
Other options, notably the active-passive failover cluster we have in HACMP or PowerHA on the AIX / IBM Power platform is unattractive as the standby node drives no resources yet must consume CPU and memory resources so that it is prepared for a failover of the primary node. We use HACMP / PowerHA with Oracle and it works nice, however Oracle RAC, even in a two-node configuration, drives load on both nodes unlike with an active-passive clustering technology.
All that aside, I am posing the question to both IBM, our Oracle DBAs (whom will ask Oracle Support). Typically the answers we get vary widely depending on the experience and skill level of the support personnel we get on both the Oracle and IBM sides... so on a suggestion from a colleague (Hi Kevin!) I posted here. I'm concerned that the answer from Oracle Support will unthinkingly be "you can't do that, my script says to tell you the absolute most rigid interpretation of the support document" while all the time the same document talks of the use of NFS and/or iSCSI storage eye roll
We have a massive deployment of Oracle EBS and honestly the interconnect doesn't even touch 100mbit speeds even though the configuration has been checked multiple times by Oracle and IBM and with the knowledge that Oracle EBS is supposed to heavily leverage RAC. I haven't met a single person who doesn't look at our environment and suggest jumbo frames. It's a joke at this point... comments like "OMG YOU DON'T HAVE JUMBO FRAMES" and/or "OMG YOU'RE NOT USING INFINIBAND WHATTA NOOB" are commonplace when new DBAs are hired. I maintain that the utilization numbers don't support this.
I can tell you that we have 8Gb fiber channel storage and 10Gb network connectivity. I would probably assume that there were a bottleneck in the storage infrastructure first. But alas, I digress.
Mainly I'm looking for a real-world answer to this question. Aside from violating every last recommendation and making oracle support folk gently weep at the suggestion, are there any issues with sharing interconnects between RAC environments that will prevent it's functionality and/or reduce it's stability?
We have rapid spanning tree configured, as far as I know, and our network folks have tuned the timers razor thin. We have Nexus 5k and Nexus 7k network infrastructure. The typical issues you'd fine with standard spanning tree really don't affect us because our network people are just that damn good.

Oracle RAC on Sun server.

Hello Oracle RAC gurus,
I have below questions, I would highly appreciate if anyone can answer these.
1) Is it must to have identical server model and configuartion for Oracle RAC?
2) I have Sun Fire 280R machine with Sun solaris 10. Can I install Oracle RAC on this
using Oracle VMWare?
3) Please let me know below scenario is possible or not,
If I have Oracle Databases(single instances) are running on my Sun server box, can I
use this machine as primary node for Oracle RAC? If this is not possible then
can I use as secondary node?
Thanks gurus.

For 1: NO, the hardware does not need to be exactly the same. The nodes can be different models, with different CPU speed and different RAM sizes. The only consideration is that they must be the same O/S. This is a hardware vendor issue. They determine which configurations they are willing to support.
For 2: RAC is currently not supported in Oracle VM.
For 3: YES, at first glance you can do this. Note that the RAC database requires a cluster database home. Thus, you would need to install a cluster database home in addition to the Single Instance database home(s). However, this answer does not consider whether or not your node would be capable of hosting another database instance in regards to performance.
Thanks.

Oracle RAC support in CIAC

Hi,
Does CIAC support Oracle RAC clusters? I'd like to put a bit of resilience on the Oracle database backend and so would like to setup an Oracle RAC. If I did would this invalidate any support if there was an issue with connectiviity to the database.
Regards,
Mohammed Rakhada

Cisco Advanced Services have a service to install using RAC One Node, and PO supports RAC as well.

Tuxedo with Oracle-RAC

Tuxedo -Oracle RAC ,
We are planning to upgrade the Tuxedo Environmet to o Support Oracle-RAC , with Single Database server with Two Instances .
***At the moment we have ceratin Tuxedo Services ( part of a transaction ) to connect Database , which is used by more than One Application ie The connection Services to the Databse is COMMON.***
Eg: we have service named DBSERVICE1 , which is connecting to a datbases , which also part of a Transaction , This DBSERVICE1 is used by more than one channels ( ATM/internet banking , phone banking etc )
we have more than one service like DBSERVICE1
With this architecture how we can effectively achieve Tuxedo -Oracle RAC High Availability.
Is is possible to specify in the Tuxedo Configuration like this " if the instance1 is down , use the Instance2"?+
Thanks in Advance.
Nadeer.

Hi Nadeer,
In Oracle RAC 10g a single global transaction that spans more than one RAC instance, yet connected to a single database will not work, i.e., you may not get transactional integrity. To solve this problem, Tuxedo introduced RAC support by way of the TUXRACGROUPS environment variable. This environment variable tells Tuxedo about the RAC configuration, i.e., which RAC instances are connected to which RAC databases. Actually it tells Tuxedo which groups of Tuxedo servers can safely participate together in a single global transaction. Using that environment variable, Tuxedo will alter its request routing algorithm so that once a transaction is started, all subsequent service requests that are part of that transaction will only be routed to servers in Tuxedo groups that can safely participate in the transaction. So if we use a simple example where there are two RAC instances R1 and R2 connected to a single database D1 and we have Tuxedo groups G1, G2, G3, and G4, where the openinfo string for G1 and G3 connect to R1 and G2 and G4 connect to R2. If a server in G1 starts a transaction, or is called by a client that has started a transaction (assuming TUXRACGROUPS has been defined properly), Tuxedo will only route all subsequent requests that are part of that transaction to servers in G1 or G3. Thus Tuxedo will prevent a transaction from ever spanning 2 or more RAC instances connected to the same database.
Again, I encourage you to read the documentation for RAC support in Tuxedo as it gives several examples and describes in detail how to define TUXRACGROUPS.
Also note that this entire problem essentially goes away in Oracle RAC 11g.

Todd Little

다음은 CRS patchset 적용 후, 문제 해결 위해 Oracle 10g 를 manual 하게 relink하는 과정입니다.
방법1. Relinking Oracle 10g (Using the command line)
[ 10g R1 ]
For Oracle 10gR1, enter one set of the following commands
a. For 32bit oracle:
# cp /opt/VRTSvcs/rac/lib/libskgxn2_32.so
/opt/ORCLcluster/rac/lib/libskgxn2.so
$ cp /opt/VRTSvcs/rac/lib/libskgxp10_ver23_32.so
$ORACLE_HOME/lib32/libskgxp.so
$ ln -s /usr/lib/libodm.so libodm10.so
b. For 64bit oracle:
# cp /opt/VRTSvcs/rac/lib/libskgxn2_64.so
/opt/ORCLcluster/rac/lib/libskgxn2.so
$ cp /opt/VRTSvcs/rac/lib/libskgxp10_ver23_64.so
$ORACLE_HOME/lib32/libskgxp.so
$ ln -s /usr/lib/amd64/libodm.so libodm10.so
[ 10g R2 ]
For 10gR2, enter one set of the following commands:
a. For 32bit oracle:
# cp /opt/VRTSvcs/rac/lib/libskgxn2_32.so
/opt/ORCLcluster/rac/lib/libskgxn2.so
$ cp /opt/VRTSvcs/rac/lib/libskgxp10_ver25_32.so
$ORACLE_HOME/lib32/libskgxp.so
b. For 64bit oracle:
# cp /opt/VRTSvcs/rac/lib/libskgxn2_64.so
/opt/ORCLcluster/rac/lib/libskgxn2.so
$ cp /opt/VRTSvcs/rac/lib/libskgxp10_ver25_64.so
$ORACLE_HOME/lib32/libskgxp.so
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.

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.

First steps on Oracle RAC 10g

Hi, Can I install Oracle Rac on one pc(nodes, storage,oracle software)? it means, I want to make some tests in order to learn about Oracle RAC. My computer has Centos 5.1 and Oracle Database 10g. I searched on Internet, but tutorial are too advanced. If you know about some sites for beginners, please, write the urls.
Thanks

you can check with the following link for install on Linux
[http://www.oracle.com/technology/pub/articles/smiley_rac10g_install.html|http://www.oracle.com/technology/pub/articles/smiley_rac10g_install.html]

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.

Please use the below link, its helpful
http://docs.oracle.com/database/121/RACAD/cvt2rac.htm
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

SAP - Oracle RAC - Linux - VMware

Hi,
we would like to install SAP on a virtual environment (VMware) on Linux RedHat platform.
For the database, Oracle RAC is certified with OCFS2 (1.6) only with Oracle Linux and not RedHat Linux 5.
Can we intstall Oracle RAC database on 2 nodes with Oracle Linux and OCFS2 and other SAP components on Redhat Linux 5 ?
Are there any issues with SAP matrix compatibility ?
Thank you!
Dan

Hi Audun,
Thank you for the links.
I can see the ASM support is new (2.2.2011)
On Note 527843 from 25.01.2011 - Oracle RAC support in the SAP environment
Using raw devices and ASM (Automatic Storage Management) is not supported in the SAP environment. In the case of ASM, there is an exception regarding the Oracle Cluster Registry (OCR) and the voting disks
and
on Note 1550133 - Oracle Automatic Storage Management (ASM) from 2 Feb 2011 they support ASM but with restrictions:
ACFS is required for RAC installations with ASM
To use ASM now, you have to migrate your database to ASM manually
Some important functions of SAP BR*Tools like backup, restore, recovery, tablespace and datafile management are not supported at the moment
Support for tablespace and datafile management is planned for Q2/2011
Also ASM instance will introduce another layer in the system with its problems, failures and resources consumption. I see on the Oracle Metalink alot of problems related to ASM. From the marketin point of view is ok, let's oracle do everything but I think if you will keep it simple it will be better.
I didn't figure out if you can directly install Oracle 11.2.0.2, they say "Allows direct SAP system installations with Oracle 11.2"
We have a vBlock hardware with flash disks as FAST Cache so I believe with 1TB of cache IO will not be a problem.
Thank you!
Dan

Oracle Rac 11GR2 installation issues;

Hi fellows. I wonder if you could help me with an issue:
I have this Oracle RAC with 2 nodes, using OS Oracle Linux 6.3 with architecture x86_64.
The installation was doing ok, but on "Prerequisite Checks" i had a problem:
"Device Checks for ASM"
Device Checks for ASM - This is a pre-check to verify if the specified devices meet the requirements for configuration through the Oracle Universal Storage Manager Configuration Assistant. Error:
"/dev/oracleasm/disks/OCR1" is not shared - Cause: Cause Of Problem Not Available - Action: User Action Not Available
Check Failed on Nodes: [cmsora02, cmsora01]
Verification result of failed node: cmsora02
Details:
PRVF-5149 : WARNING: Storage "/dev/oracleasm/disks/OCR1" is not shared on all nodes - Cause: - Action:
Back to Top
Verification result of failed node: cmsora01
Details:
PRVF-5149 : WARNING: Storage "/dev/oracleasm/disks/OCR1" is not shared on all nodes - Cause: - Action:

But, the thing is: They are Shareable.
I will prove to you:
[root@cmsora01:/root]$ oracleasm listdisks
DAT1
FRA1
OCR1
OCR2
OCR3
OCR4
OCR5
REDA1
REDB1
And
[root@cmsora02:/root]$ oracleasm listdisks
DAT1
FRA1
OCR1
OCR2
OCR3
OCR4
OCR5
REDA1
REDB1
I don't know if this proves a thing, but the disks are readable for both nodes.
Anyone has passed for this situation before ?
Any hint would be helpful.
Thanks in Advance.
Regards.

How to configure sun application server 8.2 for Oracle RAC 10g

Hello,
We have numerous boxes running the sun platform application server 8.2 and 2 boxes running enterprise version 8.2 all connecting to a 4 node Oracle RAC 10 G release 2 database. We have the system up and working. The application servers are connecting just fine to the database and the apps don't have any problems querying, inserting, etc. However, when we try to do failover testing of situations when a node or nodes of the Oracle RAC database goes down the application server does not gain new valid connections. Our configuration is this, OracleDataSource for the data source, table validation turned on with a valid table, ONS configuration set in properties, connectionCache enabled, and fastconnectionfailover enabled as well in the properties. We have that long oracle rac url with load balancing turned on set fot the database URL. We have the checkbox checked to fail all connections on any failure. ONS is configured properly within the database because we have a java application that runs outside of the application server that uses all the same settings described above (only set manually in our code for the OracleDataSource). This application works seemlessly when DB nodes are shutdown. We can shutdown all but one node and it's still humming along without skipping a beat. Start up one of the others, kill the last node, it still hums along nicely without skipping a beat. We'd really like to get the applications running in the application server to work the same way. Any help would be greatly appreciated. We've tried all the combinations that we can think of with configuration settings in the application server and it never works. Am tempted to rip out the database connection pool from inside the application server and configure it manually in the code but we are using entity beans and this is the much easier approach, if it will work. It's down to the point of does sun application server actually work with oracle RAC for connection failovers.

Hi,
We are also facing similar execption. Here is the error, we are getting, when a node is failed on RAC.
