3 1. INTRODUCTION 1.1. Purpose of Document This document provides technical information about installing Oracle Database Server 10g Intended Audience This manual is intended for IT / Support department Technical staffs that perform installation on Oracle Database Scope of this guide This document consists of 2 parts: - The first part is to list down the preparation to install Oracle Database server 10g. - The second part is to describe the steps to create and patch Oracle Database server 10g. -3-

4 2. Database Installation 2.1. Operating System Preparation Use Solaris version 8 or more advanced version in order to install database oracle 10g. The installer filename usually is 10gr2_db_sol.cpio.gz assume the Operating System is Solaris SPARC 64 bit. Copy installers and patches into /opt/installer/oracle or any directory which you select for placing the oracle 10g installers. Copy all required files from Oracle10g DVDs to install oracle 10g into installer directory. Make link for /bin/scp /bin/ssh to /usr/loca/bin/scp and ssh using root. Makes sure the server is using static IP address. Also the server must have at least three IP address, in this example four, one will be used for iscsi, for SAN emulation. Here is the example for /etc/hosts contain on both nodes node 1 ::1 localhost localhost demo01 loghost demo01-iscsi demo01-priv demo01-vip demo demo02-iscsi demo02-priv demo02-vip node 2 ::1 localhost localhost demo02 loghost demo02-iscsi demo02-priv demo02-vip demo demo01-iscsi demo01-priv demo01-vip Login as root and then create oracle s user by following below commands: groupadd oinstall groupadd dba useradd -d /export/home/oracle -g oinstall -G dba -m -s /bin/bash oracle passwd -r files oracle -4-

5 Enter a new password for the user oracle. In this case, type: password as the oracle s password. Go to the directory /export/home/oracle and then type command: vi.profile Add some content. The content much more like the below picture, however refer to the Production Setup and Deployment Documentation for detail. umask 022 if [ -t 0 ]; then stty intr ^C fi PS1='['`hostname`:$LOGNAME']$ ' DISPLAY= :0.0 TEMP=/tmp TMPDIR=$TEMP export PS1 DISPLAY TEMP TMPDIR ORACLE_SID=APRRAC ORACLE_BASE=/opt/oracle ORACLE_HOME=$ORACLE_BASE/10g ORACLE_ADMIN=$ORACLE_BASE/admin ORA_CRS_HOME=$ORACLE_BASE/crs ORA_ASM_HOME=$ORACLE_BASE/asm TNS_ADMIN=$ORACLE_HOME/network/admin LD_LIBRARY_PATH=$ORACLE_HOME/lib PATH=$ORACLE_HOME/bin:$ORACLE_HOME/OPatch:/usr/ccs/bin:/usr/bin:/usr/ sbin:/usr/openwin/bin:/usr/local/bin:$path export ORACLE_SID ORACLE_BASE ORACLE_HOME ORACLE_ADMIN ORA_CRS_HOME ORA_ASM_HOME TNS_ADMIN LD_LIBRARY_PATH PATH To check the result login as oracle user by typing su - oracle env Set the installation directory structure and refer to the Production Setup and Configuration Documentation for the location, it can be done by following below commands: mkdir /opt/oracle. This is for setting up the ORACLE_BASE. mkdir /opt/oracle/10g. It will become ORACLE_HOME. mkdir /opt/oracle/crs. It will become ORA_CRS_HOME. mkdir /opt/oracle/asm. It will become ORA_ASM_HOME. chown R oracle:oinstall /opt/oracle. The command will make the installation tree to be possessed by oracle user. chmod R 775 /opt/oracle. By applying this command, Oracle Installer can write what it needs into the directory. -5-

6 At this instant, the next step is setting up the kernel parameters by doing below operations. To create the resource project that will be used by user oracle, type projadd oracle Navigate to directory /etc and type edit user_attr. It will be viewed as below figure first. cd /etc vi user_attr It will be viewed as this figure below # Copyright (c) 2003 by Sun Microsystems, Inc. All rights reserved. # /etc/user_attr # user attributes. see user_attr(4) #pragma ident "@(#)user_attr /07/09 SMI" adm::::profiles=log Management lp::::profiles=printer Management root::::auths=solaris.*,solaris.grant;profiles=web Console Management,All;lock_after_retries=no You need to add a new line to the end of this file that reads: Append this line oracle::::project=oracle That means the user oracle will be assigned to the new resource project called oracle whenever he logs on. The shared memory segments must be upgraded into the specified size of project.max-shm-memory in the Production Setup and Deployment. So, open a new terminal session and login as root user. After that, perform following command (for example the value of project.max-shm-memory is 14GB): prctl -n project.max-shm-memory -v 14gb -r -i project oracle Using user oracle perform this command to check the value of project.max-shmmemory: prctl -n project.max-shm-memory -i project oracle Also, you have to make the value of shared memory becomes permanent by performing this command as root user: projmod -s -K "project.max-sem-ids=(priv,100,deny)" oracle projmod -s -K "process.max-sem-nsems=(priv,256,deny)" oracle projmod -s -K "project.max-shm-memory=(priv,14gb,deny)" oracle projmod -s -K "project.max-shm-ids=(priv,100,deny)" oracle projmod -s -K "process.max-file-descriptor=(priv,65536,deny)" oracle Oracle Clusterware requires every nodes to be able to communicate through SSH, RSH without using password. There are several settings need to be done: -6-

7 login as oracle user, and execute these commands; cd mkdir.ssh chmod 755.ssh ssh-keygen -t rsa ssh-keygen -t dsa copy id_rsa.pub and id_dsa.pub to another node as ~/.ssh/authorized_keys file cat ~/.ssh/id_rsa.pub ssh 'cat >>.ssh/authorized_keys' cat ~/.ssh/id_dsa.pub ssh 'cat >>.ssh/authorized_keys' chmod 644 ~/.ssh/authorized_keys also add rsa and dsa public key of their own node cat id_rsa.pub >> authorized_keys cat id_dsa.pub >> authorized_keys exec /usr/bin/ssh-agent $SHELL /usr/bin/ssh-add test ssh login to each node using three IP that configured from node1 ssh ssh from node2 ssh ssh make sure each node are added in their own known_hosts configure rsh and rlogin create file hosts.equiv in /etc with ownership root:root and mod 600, that contain (hostname) (oracle user) demo01 oracle demo02 oracle create file.rhosts in /etc using root and insert demo01,demo02 to prevent X11 Forwarding (optional) create file ~/.ssh/config and insert this line Host * ForwardX11 no Oracle Clusterware also requires time synchronization between nodes, usually NTP is used. If not, make one of the node (node1) as the time server by enabling the feature using this command: svcadm enable time:stream svcadm enable time:dgram -7-

8 To start syncing the time in the client (node2) server login as root and type: rdate ip-server-node1 Check Oracle Solaris Package dependancies using this command: pkginfo -i SUNWarc SUNWbtool SUNWhea SUNWlibm SUNWlibms SUNWsprot SUNWtoo SUNWi1of SUNWi1cs SUNWi15cs SUNWxwfnt if there are missing package add it using command: pkgadd d /location/required/package If SAN is replaced by iscsi, use this command to mount it: login as root, and type iscsiadm add discovery-address ip-address-iscsi-server iscsiadm modify discovery --sendtargets enable devfsadm -i iscsi iscsiadm list target -S check the disk using format command Creating RAW disk: When creating partition using format command always start from cylinder 1 instead 0 Initialize the devices, with command, repeat for each partition that will be used at each disk dd if=/dev/zero of=/dev/rdsk/c*t*d*s* bs=8192 change ownership and mod chown root:dba /dev/rdsk/c*t*d*s* chmod 660 /dev/rdsk/c*t*d*s* create a link to a specified path that easily accessible /opt/oracle/disk with ownership oracle:dba # ln -s /dev/rdsk/c2t3d0s6 ocr1 # ln -s /dev/rdsk/c2t4d0s6 ocr2 # ln -s /dev/rdsk/c2t5d0s6 vote1 # ln -s /dev/rdsk/c2t6d0s6 vote2 # ln -s /dev/rdsk/c2t7d0s6 vote3 # ln -s /dev/rdsk/c2t8d0s6 asm # ln -s /dev/rdsk/c2t9d0s6 data1 # ln -s /dev/rdsk/c2t10d0s6 data Installing Oracle Clusterware Before installing Oracle Clusterware (CRS) check the prerequiste by using this command. -8-

9 ./cluvfy stage -pre crsinst -n demo01,demo02 verbose The result of this test there must be no error, warning still acceptable. Login as oracle user and navigate to the specific directory where Oracle CRS installer placed (10gr2_cluster_sol.cpio.gz). Execute the installer by following this command:./runinstaller Commonly, there will be an error like this: This might happened because IP address is not correctly configured while setting up the environment display parameter. See below figure in detail. Therefore, edit localhost to your ip address in.profile file or using this command for temporary solution: bash export DISPLAY=your-pc-ip-address:0.0 Then the installer will showed up -9-
