First, create a linked clone of the OEL5.5 VM created in part one; call it something not stupid - like OEL5.5 OEMGRID. Quick note: you might need to bump the memory of this virtual machine to at least 1.5GB else the Oracle Database installer will complain; that did not happen the first time I did this but the second time I was about 3K (yes, 3 measly F'ing K) short of the minimum.
Start the cloned VM and log in as root.
I had the luxury of having a domain name and static IP address so I used the following tool to configure my network and then edited /etc/hosts:
10.9.8.7 grouch1.grouch.net grouch1
I would reboot now so the rest can be handled through ssh and cut and paste (unless you like typing).
Oracle Database Preinstallation Requirements
Most of the chapter two Preinstallation Requirements have been set by installing .rpm package oracle-validated (part one). The oracle-validated .rpm installs all Oracle Database dependancies and also modifies /etc/sysctl.conf, /etc/security/limits.conf, /etc/modprobe.conf and /boot/grub/menu.lst to include kernel parameters. It also creates some of the users and groups. Login as root and execute this to finish up and add an administrative user:
/usr/sbin/usermod -g oinstall -G dba,oper,oracle oracle
/usr/sbin/usermod -g grouchy -G dba,wheel grouchy
Next step is to create the directories where software will be installed, for database files and for recovery files (note: in real life production land these could be on separate disks or one gigundous LUN, but we are happy fun test land so who cares)
mkdir -p /u01/app/oracle
mkdir -p /u02/oradata
mkdir -p /u03/recovery_area
chown -R oracle:oinstall /u01/app/oracle /u02/oradata /u03/recovery_area
chmod -R 775 /u01/app/oracle /u02/oradata /u03/recovery_area
A reboot is not required but why not (what better way to test what you screwed up). Now might also be a good time to take a snapshot in VMWare.
Oracle Grid Infrastructure
The OEM VM will not be clustered and will not be using Automatic Storage Management (ASM) so the Grid Infrastructure for standalone server and Oracle Cluster Synchronization Services (CSS) are not required.
Installing Oracle Database
Login to the VM as root. Connect the database .iso image as a DVD or mount the DVD and connect that to the VM. If empty directory /media/cdrom does not exist then make it. As root, mount the CD (mount -t iso9660 -o ro /dev/cdrom /media/cdrom).
I use PuTTY with X11 forwarding enabled in my Ubuntu workstation (that I am running VMWare Workstation on) to connect to the VM as user oracle and do the installation.
First, edit ~/.bash_profile and append the following:
export ORACLE_BASE ORACLE_SID
Do a quick . .bash_profile to execute that script. Next, create some directories in the oracle user home (personal preference):
for i in backup crap expimp junk log run save scripts sql temp
- Skipped security updates; Yes
- Installation Option; Install database software only
- Grid Options; Single instance database installation
- Product Languages
- Database Edition; Enterprise Edition
- Installation Location; Oracle Base: /u01/app/oracle Software Location: /u01/app/oracle/product/11.2.0/dbhome_1
- Create Inventory; /home/oracle/oraInventory; *1
- Operating System Groups;
- Prerequisite Checks; all passed
- Install Product;
*1 pure laziness on my part because the preinstallation instructions never made nor setup privileges on the default /u01/app/oraInventory but now that I think about it the inventory directory should be outside of the whole OFA structure.
Oracle Database Postinstallation Tasks
I did not do anything here.
Go to Tahiti and check out the installation guide for more information
- Corrected errors, added smart-ass comments, etc. blah blah blah...
