ORACLE GRID INFRASTRUCTURE INSTALLATION

Steps to improve the screen resolution any LINUX flavours. Here is how you fix that

problem

# cd /etc/X11# vi xorg.conf

Step 1: Install X and GNOME, if not already present.yum groupinstall "X Window System" "GNOME Desktop Environment"[Note: to install KDE, substitute the "GNOME..." string with "KDE (K DesktopEnvironment)"]

Step 2: Edit /etc/X11/xorg.confYou should already have

Section "Device"Identifier "Videocard0"Driver "vmware"EndSection

Add the following monitor section

Section "Monitor"Identifier "Monitor0"HorizSync 1.0 - 10000.0VertRefresh 1.0 - 10000.0EndSection

Modify the existing Screen sectionNote to replace the following 16001200 string with the highest resolution yourmonitor can handle.

Section "Screen"Identifier "Screen0"Device "Videocard0"Monitor "Monitor0"DefaultDepth 24SubSection "Display"Viewport 0 0

Depth 24Modes "1600x1200" "800x600" "640x480"EndSubSectionEndSection

Step 3: Start X# startxxauth: creating new authority file /root/.serverauth.3481

Add the below values to configure the Kernel values.

Once saved to reflect the changes give the below command

# sysctl -p

Create Oracle user and group and create the directory and change permission

# groupadd -g 1000 oinstall

# groupadd -g 2000 dba

# useradd -g oinstall -G dba -d /home/oracle -u 1002 -m oracle

# passwd oracle

Output: Changing password for user oracle.

New UNIX password:BAD PASSWORD: it is based on a dictionary wordRetype new UNIX password:passwd: all authentication tokens updated successfully.

# mkdir -p /u01/app/oracle

# chown oracle:oinstall -R /u01/

# chmod -R 755 /u01/

# fdisk -l

number of cylinders for this disk is set to 3263.There is nothing wrong with that, butthis is larger than 1024, and could in certain setups cause problems with:1) software that runs at boot time (e.g., old versions of LILO)2) booting and partitioning software from other OSs

Once the ASM RMPs are installed create disk for ASM

# /etc/init.d/oracleasm createdisk DISK1 /dev/sdb5

# /etc/init.d/oracleasm listdisks

DISK1

# /etc/init.d/oracleasm querydisk -p DISK1

Disk "DISK1" is a valid ASM disk

/dev/sdb5: LABEL="DISK1" TYPE="oracleasm"

# chmod -R 777 /dev/sdb*
