Oracle RAC IP Configuration

Hi all
How Oracle RAC IP configuration uses gateway.
Thanks in advance,
Sarathi

Hi Friend,
Thumb Rules :
1. All public NICs must have the same name on all nodes in the cluster
2. Similarly, all private NICs must also have the same names on all nodes
Use component verifications commands like 'nodereach' or 'nodecon' for this purpose. Type cluvfy comp -help on the command prompt. If the 'cluvfy comp nodecon' command is invoked without -i, cluvfy will attempt to discover all the available interfaces and the corresponding IP address & subnet. Then cluvfy will try to verify the node connectivity per subnet.
You can run this command in verbose mode to find out the mappings between the interfaces, IP addresses and subnets. You can check the connectivity among the nodes by specifying the interface name(s) through -i argument
Note : If you metalink support, there is a step by step document *RAC and Oracle Clusterware Best Practices and Starter Kit (Linux) [ID 811306.1]*

I am confused about this ip setup Especially private and VIP.
Can anyone help on this please
Thanks,

Yes thanks for the reply. i did that yesterday with Oracle VM and i am almost finished with my setup.
Found this article on net which has clear explanations. If someone need this it they can use this.

RAC - Oracle Grid Infrastructure configure failed

Hi, am trying to install 2 node RAC on Oracle VMs. Before the installation during the -preinst check there were few issues which were resolved (ex user equivalence). After that during the installation process of the Grid it failed at step "Configure Oracle Grid Infrastructure for a cluster". After it failed at this step, subsequent steps too failed which I asked OUI to ignore and then I ran both the post installation scripts. And then ran post crsinst which failed. Pasting below the output of the root.sh script, post crsinst and other checks.

Please help.

before installation have u configure the private interconnect on both the nodes to same network adapter..
for example on node 1 if the private interconnect is on eth0 then on the node 2 it should use eth0 only...
for private interconnect use the hostonly option on both the nodes in the network configuration page of the vmware or virtual box..
and for public network it can be bridged
more over if you are installing on the laptop its good to configure the SSH using the OUI.. rather than doing it manually.. as it saves time
the private and the public networks should not have same range of ip address. like if public address are like 192.168.2.222/255.255.255.0 and private address have to be different like 10.10.1.2/255.0.0.0 (this is just an example)
have to configured the NTP.
any ways try installing the oracle rac on virtual box follow the steps given the below website they are pretty straight forward...

Oracle RAC 11G - Service configuration

Hi,
I have been reading a lot of documentation regarding oracle services and I have an ok understanding of how they work. However, I have a general question regarding configuring services using Oracle RAC. For instance, if I have a 2 node oracle 11GR2 RAC on a Linux Redhat server. I have an application that connects to a service I have created. I create the service as follows.
srvctl add service -d ORCL_RAC -s APP_SERVICE -r ORCL_RAC1,ORCL_RAC2
The tnsnames contains:
APP_OLTP =
(DESCRIPTION =
(LOAD_BALANCE = ON)
(FAILOVER = ON)
(ADDRESS = (PROTOCOL = TCP)(HOST = server01)(PORT = 1521))
(ADDRESS = (PROTOCOL = TCP)(HOST = server02)(PORT = 1521))
(CONNECT_DATA =
(SERVICE_NAME = APP_SERVICE)
(FAILOVER_MODE =
(TYPE = SELECT)
(METHOD = BASIC)
(RETRIES = 20)
(DELAY = 1)
My questions are as follows:
1) When I do a 'srvctl status service -d ORCL_RAC', should I see the service running on both nodes of the RAC? Or does it run only one node, then it will fail over to the other when needed?
2) If I have a RAC environment where I see two services created (RAC_SRV1 and RAC_SRV2). I see that RAC_SRV1 is only running on node1 and RAC_SRV2 is only running on node2. There are two applications sharing the same database, one application is using RAC_SRV1 and the other application is using RAC_SRV2. Am I correct in thinking that there is no failover available here? If node1 goes down, the application connecting to RAC_SRV1 will not be able to connect to node2 right?
3) In the case of the scenario in question 2 above, would it be best practise to simply create one service and have both applications connecting to the one service? Could I configure the one service to point connections from one application to node1 and connections from the other application to node2?

1) When I do a 'srvctl status service -d ORCL_RAC', should I see the service running on both nodes of the RAC? Or does it run only one node, then it will fail over to the other when needed?you can see its running on both nodes.
use option -a in srvctl ( A list of available instances to which the service fails over when the database is administrator managed.)
http://docs.oracle.com/cd/E11882_01/rac.112/e16795/srvctladmin.htm#i1008562

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.

Oracle RAC on Solarais Configuration Issue

Hi,
We are trying to install Oracle RAC 10g R2 on Solaris 10.
Following are the products
1=> Soalris 10 OS
2=> Sun Cluster 3.1
3=> Veritas Volume Manager
4=> Veritas Cluster File System
Can i deploy Oracle RAC using the above listed Software.
Here we have not purchase any of the Cluster Volume Manager.
Is the CVM required to install Oracle RAC.
Is there any alternative wherein we can install Oracle RAC without using CVM like for example using the RAW device where the VM will manage storage from a single node rather than buying the CVM that will allow to manage the storage from multiple nodes.
Also i would like to highlight is suggestion for using ASM is rule out hence ASM would not be used.
Can anyone suggest me some solution to the above problem.

Well, my impression is that you don't really know what your requirements are and you are trying to fit the technologies somehow. Worse yet, there is no clear understanding how those technologies fit together and as long as you explain what your vendor is saying you (which vendor?) they don't have clear idea either.
I would also suggest to review your decision to use Sun Network Data Replicator for DR site. Consider Oracle Physical Standby database instead - it's more flexible solution and doesn't limit your choice of storage stack.
1) Do Oracle RAC 10gR2 requires any Veritas Cluster Volume Manager
Words "any" and "Veritas" contradict in your question. But the answer is no. RAC require shared storage which can generally be one of those:
- raw devices with or without some kind of cluster volume manager
- cluster file system
- NAS storage (NFS mounted)
- ASM with raw devices for CRS files (OCR and voting disks)
2) Does Oracle RAC 10g R2 require any Vertias Cluster File System or it can sit on normal Vertias File System
Again, Oracle database files MUST reside on shared storage and non-clustered file system is not an option.
3) Is there any solution where we can use the Sun Cluster with Veritas Componets to configure RAC.
If I recall correctly, Sun Cluster includes in it's license some of component of Veritas storage stack. So you might be all set. You should turn to documentation on that stage and see exactly what you have licensed and if your stack allows shared storage. You might want to have a look at http://www.sun.com/software/whitepapers/solaris10/solaris_cluster.pdf
and Oracle Certification Matrix on Metalink.

Oracle RAC on two different configuration systems

Can we install Oracle RAC (Standard Edition) on severs having different configuration -
1. Server 1 - IBM x3850 - 2 processors occupied, 128 GB RAM, windows server 2008 R2 64 bit
2. Server 2 - IBM 3650 - 2 processors, 64 GB RAM, windows server 2008 R2 64 bit
Thanks & Regards

Dear Billy
The storage will be on IBM SAN with fibre channel connectivity for both the servers.
The node A will be only for production and Node B for non production. Pl suggest your recommendations.So, you will configure node1 for database1(instance1) and node2 for database2(instance1)? So much for fail-over... For your proposed configuration, why waste the extra RAC license if you are only going to have the prod db running on a single node? Also Windows???? And you are paying for Windows SERVER licenses as well??? Why? Linux (even Oracle Enterprise Linux) is free and the support cost are far less than for Windows. It is slow and is a nightmare to manage. Learn Linux or AIX or something. I don't do Windows and I certainly would never deploy RAC on Windows. (My deployment of RAC clusters now stands > 75 clusters with the largest at 250TB and NONE of them on Windows).
This is more like RAC-One than RAC. I have a problem using a single RAC cluster to support both my production and non-production work. It also negates the primary reason to use RAC - high availability. In your proposed solution, if your production db goes down on node1(instance1) your application is dead. In RAC, when the middle-tier attempts to reconnect, it would simple connect to a surviving node. You will not have that feature in your proposed configuration.
I also would object to the notion of having production database in the same set of DiskGroups (ASM) or file systems as my non-production data. There are too many times where I have seen a someone execute a process that brought the entire system down due to high I/O - now, if you have this configuration, it is conceivable that your non-prod I/O could affect your production (SAN switch overload, Storage array overload etc...). And all of this does not include the "oops-factor". That's what happens when you thought you were deleting data files for your non-prod database that you want to restore and "accidently" delete production data files.
You asked for suggestions --
1) buy more hardware
2) have 1 standalone for non-prod
3) have 2 nodes for RAC - deploy production only here.

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

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

How configure Tuxedo 8.1 to Oracle RAC 9.1

I need to configure Tuxedo 8.1 to work with Oracle RAC 9i, I saw that there's documentation to configure for Tuxedo 9i with Oracle RAC 10g. But this is not my scenario. If someone know how to do this, could send me some documentation or example to apply this. I already read ads.pdf from BEA dev2dev site and this documentation don't talk about Oracle 9i

Weverton,
Later versions of Oracle contain significant RAC-related features not
present in earlier versions of RAC, so Tuxedo
(For example, Oracle 10gR2 contains support for DTP services, and Oracle
10.1.0.3 contains support for Fast Application Notification.)
Because one or more of these features is required for RAC migration and
recovery in Tuxedo, Tuxedo offers support only for Oracle 10.1.0.3 and above
for general RAC architectures. (However, there are some specialized RAC
application architectures, such as architectures where only a single service
is called in each transaction and architectures where transactions are not
used where Tuxedo can work with Oracle 9i.) Significant improvements in
RAC have occurred with each Oracle release, so if it is possible to upgrade
to Oracle 10gR2 then you should do so.

Cat 6K configuration settings for Oracle RAC

Does anyone have experience with Cat6K design and configuration best practices for Oracle RAC?
TIA
Bill

Bill, personally I have not supported oracle real app clustering, however,I think you may find very good architecture information on this pdf link, is this more or less what you are looking for?

Am in process of installation of ORACLE RAC 10.2.0.3 using cluvfy 10.2.0.3 with EMC storage (multipathing)
need ur help..i had done with following things...
1)i had done with prerequisite steps..
2)user equivalence .
3)cluvfy checks...
4)in process to install ORACLE RAC but the storage assign to server is EMC Clarion but the disk assign is having same name but diffferent
major number minor number...
pls let me know..
1)major number minor number with repect to voting ,ocr and asm disk..
2)while configuring EMC storage how same mojor and minor number are assign(if possible compltee steps)
Thanks

Configure Oracle DB Adapter in Oracle RAC configuration

Oracle RAC uses Service name rather than SID and Oracle adpater only accepts a URL string in sid format. How can a connection be defined for a RAC environment?

Thank you. The solution for configuring a Tidal adapter that uses Oracle RAC is to expand the URL connection string where the Service name can be defined.
Standard defined connection string:
jdbc:oracle:thin:@hostname:1521:sid
Connection string for Oracle RAC:
jdbc:oracle:thin:@(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=hostname)(PORT=1521)))(CONNECT_DATA=(SERVICE_NAME=servicename)))

RMAN configuration in ORACLE RAC database

Hi there,
We are using RMAN backup strategy for taking backups from one node(eg.node1).Database is RAC database, version 9.2.3. and OS is Solaris 5.10.
this is the configuration which we use, as follows:
Connecting to Prod.Database using catalog database.
rman catalog=rman/rman@CATDB target=sys/oracle@PRODDB(node 2).
RMAN> show all;
RMAN configuration parameters are:
CONFIGURE RETENTION POLICY TO REDUNDANCY 30;
CONFIGURE BACKUP OPTIMIZATION ON;
CONFIGURE DEFAULT DEVICE TYPE TO DISK; # default
CONFIGURE CONTROLFILE AUTOBACKUP ON;
CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO '/rmanback/_%F';
CONFIGURE DEVICE TYPE DISK PARALLELISM 5;
CONFIGURE DATAFILE BACKUP COPIES FOR DEVICE TYPE DISK TO 1; # default
CONFIGURE ARCHIVELOG BACKUP COPIES FOR DEVICE TYPE DISK TO 1; # default
CONFIGURE CHANNEL DEVICE TYPE DISK FORMAT '/rmanback/CMWPROD_%s.bak';
CONFIGURE CHANNEL 2 DEVICE TYPE DISK CONNECT 'SYS/oracle@PRODDB(node2)';
CONFIGURE MAXSETSIZE TO 7 G;
CONFIGURE SNAPSHOT CONTROLFILE NAME TO '/oracle/9.2.3/dbs/snapcf_CMWPROD1.f';
As the above config shows RMAN is connecting to PROD DB (node 2). But we need to take backups (datafiles and as well as archive logs) from two nodes (i.e from node 1 and as well as node 2).
Is there any possibility for taking backups from two nodes?
Thanks,
Balu.

You will need to setup an NFS share such that both nodes can access each other's archived redo logs area. You also need to ensure your LOG_ARCHIVE_DEST_n parameter settings are properly set. Once setup correctly, either node will be able to run the backup and include each other's archived redo log files. Since this is RAC, the data files are shared by design and either node can already backup these files.
Multiple channels would allow 'simultaneous' backup of the archived redo logs.
I would highly recommend using a CFS (single shared file system where all nodes store their archived redo logs distinguished by thread) to store the archived redo logs, this reduces administration and configuration especially when you get ready to scale.
Hope this helps.
