Oracle 10203 RAC Environment Add new node (ii) Establishment of cluster software

Briefly describe the process of adding a node in the Oracle 10203 for Solaris SPARC Dual-node environment. Shared storage is already configured on a third node, which focuses on the configuration on the operating system and on Oracle.

This article describes the establishment of cluster software.

On the new node racnode3, authorize the bare devices on the shared storage to the Oracle User:

bash-3.00# Chown oracle:oinstall/dev/rdsk/c1t500601603022e66ad*

Establish a consistent/dev/rac/vot and/DEV/RAC/OCR link with node 1, Node 2, and execute the same raw device file:

bash-3.00# Mkdir/dev/rac

bash-3.00# ln-s/DEV/RDSK/C1T500601603022E66AD2S1/DEV/RAC/OCR

bash-3.00# ln-s/dev/rdsk/c1t500601603022e66ad2s3/dev/rac/vot

Perform $ora_cls_home/out/bin/addnode.sh at the installation node to start the graphical interface to add new nodes:

bash-2.03$./addnode.sh

In the graphical interface, fill in the name of the new node's public, private, and VIP counterparts.

The installation process Oracle skips some remote execution errors, requires manual corrections, and executes the following script on the RACNODE3:

bash-3.00$/data/oracle/product/10.2/crs/oui/bin/runinstaller-attachhome-noclusterenabled ORACLE_HOME=/data/ Oracle/product/10.2/crs oracle_home_name=oracrs10g_home1 cluster_nodes=racnode1,racnode2,racnode3 CRS=true " Inventory_location=/data/oracle/orainventory "Local_node=racnode3

Starting Oracle Universal Installer ...

Checking Installer Requirements ...

Checking operating system version:must be 5.8, 5.9 or 5.10. Actual 5.10

Passed

Checking Temp space:must be greater than MB. Actual 10167 MB passed

Checking swap space:must be greater than MB. Actual 7415 MB passed

All installer requirements met.

' Attachhome ' was successful.

Execute the following script on Node 2:

bash-2.03$/data/oracle/product/10.2/crs/oui/bin/runinstaller-updatenodelist-noclusterenabled ORACLE_HOME=/data/ Oracle/product/10.2/crs cluster_nodes=racnode1,racnode2,racnode3 crs=true "inventroy_location=/data/oracle/ Orainventory "Local_node=racnode2

Starting Oracle Universal Installer ...

Checking Installer Requirements ...

Checking operating system version:must be 5.8, 5.9 or 5.10. Actual 5.8

Passed

Checking Temp space:must be greater than MB. Actual 8233 MB passed

Checking Monitor:must is configured to display at least 256 colors. Actual 16777216 passed

All installer requirements met.

' Updatenodelist ' was successful.

Run a similar script on node 3:

bash-3.00$/data/oracle/product/10.2/crs/oui/bin/runinstaller-updatenodelist-noclusterenabled ORACLE_HOME=/data/ Oracle/product/10.2/crs cluster_nodes=racnode1,racnode2,racnode3 crs=true "inventroy_location=/data/oracle/ Orainventory "Local_node=racnode3

Starting Oracle Universal Installer ...

Checking Installer Requirements ...

Checking operating system version:must be 5.8, 5.9 or 5.10. Actual 5.10

Passed

Checking Temp space:must be greater than MB. Actual 10167 MB passed

Checking swap space:must be greater than MB. Actual 7415 MB passed

Checking Monitor:must is configured to display at least 256 colors. Actual 16777216 passed

All installer requirements met.

' Updatenodelist ' was successful.

You will then need to execute the following script sequentially:

1./data/oracle/orainventory/orainstroot.sh on Node 3:

bash-3.00#./data/oracle/orainventory/orainstroot.sh

Creating the Oracle inventory pointer file (/VAR/OPT/ORACLE/ORAINST.LOC)

Changing permissions of/data/oracle/orainventory to 770.

Changing groupname of/data/oracle/orainventory to Oinstall.

The execution of the script. is complete

2./data/oracle/product/10.2/crs/install/rootaddnode.sh on Node 1:

#./data/oracle/product/10.2/crs/install/rootaddnode.sh

Clscfg:existing configuration version 3 detected.

Clscfg:version 3 Is10grelease 2.
