RAC Build on Solaris : Second Phase

Oracle 10g R2 RAC Installation for Temp Nodes:
Step by Step instructions for installing Oracle 10g R2 RAC installation. The procedures will provide STEP by STEP guide you for installing two nodes (tempracsrv3 and tempracsrv4). Installation on this phase includes documentation on how to verify the installation and configuration is installed correctly. Step by Step instructions on creating RAC database, importing schemas from oracle 9i database into new databases, and testing database and node connectivity for this phase of the step by step instructions.

10g RAC Installation (Part-II Clusterware & Database Installation)

1. Install Oracle Clusterware

Mount the Clusterware dvd in the tempracsrv3 and run the runInstaller

After downloading, as the oracle user on tempracsrv3, execute

1. Welcome: Click on Next.

2. Specify Inventory directory and credentials:

o Enter the full path of the inventory directory:

/u01/app/oracle/oraInventory.

o Specify Operating System group name: oinstall.

3. Specify Home Details:

o Name: OraCrs10g_home

o /u01/app/oracle/product/10.2.0/crs_1

4. Product-Specific Prerequisite Checks:

o Ignore the warning on physical memory requirement.

5. Specify Cluster Configuration: Click on Add.

o Public Node Name: tempracsrv4.mycorpdomain.com

o Private Node Name: tempracsrv4-priv.mycorpdomain.com

o Virtual Host Name: tempracsrv4-vip.mycorpdomain.com

6. Specify Network Interface Usage:

o Interface Name: eth0

o Subnet: 192.168.2.0

o Interface Type: Public

o Interface Name: eth1

o Subnet: 10.10.10.0

o Interface Type: Private

7. Specify Oracle Cluster Registry (OCR) Location: Select External Redundancy.

For simplicity, here you will not mirror the OCR. In a production environment,

you may want to consider multiplexing the OCR for higher redundancy.

o Specify OCR Location: /u01/ocr_config

8. Specify Voting Disk Location: Select External Redundancy.

Similarly, for simplicity, we have chosen not to mirror the Voting Disk.

o Voting Disk Location: /u01/votingdisk

9. Summary: Click on Install.

10. Execute Configuration scripts: Execute the scripts below as the root user

sequentially, one at a time. Do not proceed to the next script until the current

script completes.

o Execute /u01/app/oracle/oraInventory/orainstRoot.sh on tempracsrv3.

o Execute /u01/app/oracle/oraInventory/orainstRoot.sh on tempracsrv4.

o Execute /u01/app/oracle/product/10.2.0/crs_1/root.sh on tempracsrv3.

o Execute /u01/app/oracle/product/10.2.0/crs_1/root.sh on tempracsrv4.

The root.sh script on tempracsrv4 invoked the VIPCA automatically but it failed with the

error “The given interface(s), “eth0″ is not public. Public interfaces should be

used to configure virtual IPs.” As you are using a non-routable IP address

(192.168.x.x) for the public interface, the Oracle Cluster Verification Utility

(CVU) could not find a suitable public interface. A workaround is to run VIPCA

manually.

11. As the root user, manually invokes VIPCA on the second node.

# /u01/app/oracle/product/10.2.0/crs_1/bin/vipca

Welcome: Click on Next.

Network Interfaces: Select eth0.

Virtual IPs for cluster nodes:

o Node name: tempracsrv3

o IP Alias Name: tempracsrv3-vip

o IP address: 192.168.2.31

o Subnet Mask: 255.255.255.0

o Node name: tempracsrv4

o IP Alias Name: tempracsrv4-vip

o IP address: 192.168.2.32

o Subnet Mask: 255.255.255.0

Summary: Click on Finish.

Configuration Assistant Progress Dialog: After the configuration has completed,

Click on OK.

Configuration Results: Click on Exit.

Return to the Execute Configuration scripts screen on tempracsrv3 and click on OK.

Configuration Assistants: Verify that all checks are successful. The OUI does a

Clusterware post-installation check at the end. If the CVU fails, correct the

Problem and re-run the following command as the oracle user.

tempracsrv3-> /u01/app/oracle/product/10.2.0/crs_1/bin/cluvfy stage -post crsinst -n tempracsrv3, tempracsrv4
