Oracle Database Install AIX

Pre Installation Tasks

Oracle database has several requirements. Please note that this article is purely for my environment because we don't use an out-of-the-box installation but AIX SOE. I can skip these steps because they are all taken care of in the SOE, or because the blades are specifically bought for this purpose and meet requirements by far:

  • X Window System requirements
  • Hardware requirements
  • Operating System level
  • Operating System filesets
  • Network setup
  • Check for unprivileged user nobody

Creating Users and Groups

Oracle Inventory Group (oinstall)

You must create this group the first time you install Oracle software on the system. The usual name chosen for this group is oinstall. This group owns the Oracle inventory, which is a catalog of all Oracle software installed on the system.

sudo mkgroup oinstall

Creating the OSDBA Group (dba)

You must create this group the first time you install Oracle Database software on the system. It identifies operating system user accounts that have database administrative privileges (the SYSDBA privilege).

sudo mkgroup dba

Creating the OSOPER group (oper)

This is an optional group. Create this group if you want a separate group of operating system users to have a limited set of database administrative privileges (the SYSOPER privilege).

sudo mkgroup oper

Creating the Oracle Software Owner User (oracle)

Note: most security auditors will not let you have an user called oracle, so keep that in mind.

You must create this user the first time you install Oracle software on the system. This user owns all of the software installed during the installation. This user must have the Oracle Inventory group as its primary group. It must also have the OSDBA group as secondary groups.

sudo mkuser pgrp="oinstall" groups="oinstall,dba,oper" shell='/bin/bash' rlogin='false' sugroups='ALL' su='true' loginretries='10' maxage='0' maxrepeats='8' minlen='5' minother='1' maxexpired='-1' minalpha='3' minage='0' histsize='0' histexpire='0' fsize='-1' cpu='-1' data='-1' stack='-1' "oracle"


And set the password:

>sudo passwd oracle

Changing password for "oracle"
oracle's New password:
Re-enter oracle's new password:

>sudo pwdadm -c oracle

System Environmentals

You need to set the maximum number of processes users are allowed to run:

sudo chdev -l sys0 -a maxuproc='2048' 

Oracle Directories

/opt>sudo mkdir oracle
/opt>sudo chown oracle:oinstall oracle

Gives:

drwxr-xr-x   2 oracle   oinstall        256 Mar 19 11:22 oracle

Installation

One note: I am not allowed to log in on the server using a local account (due to the security policy) so I first need to login using my personal account, su to the oracle user and then run the installation. But because I'm su-ing, I cannot use the X Server authentication for my account, why not, and how to solve this is explained in this section. When you've downloaded the software you have to unpack the software before you can install it:

Unzip:
oracle@oracledbbox:/tmp/sft>gunzip 10gr2_aix5l64_database.cpio.gz
Extract:
oracle@oracledbbox:/tmp/sft>cpio -idcmv < 10gr2_aix5l64_database.cpio

When you run the rootpre script and you run into the error below it's because you did not acquire patch 6613550:

Configuring Asynchronous I/O....
Asynchronous I/O is not installed on this system.
You will need to install it, and either configure it yourself using
'smit aio' or rerun the Oracle root installation procedure.

Configuring POSIX Asynchronous I/O....
Posix Asynchronous I/O is not installed on this system.
You will need to install it, and either configure it yourself using
'smit aio' or rerun the Oracle root installation procedure.

The solution is to run a modified rootpre script as supplied in patch 6613550 (see links above):

root@oracledbbox:/tmp/sft>./rootpre.sh
./rootpre.sh output will be logged in /tmp/rootpre.out_10-04-20.10:58:08

Set (or check) the LANG parameter for the system:

Now it's time to install the oracle database software. Again, you need to be able to redirect X to your local machine. See here for more information.

Now you have to enter the oracle home data, the following list shows the Oracle homes maintained on AIX:

  • All Oracle homes that are already created using OUI
  • All homes as defined in the /etc/oratab or /var/opt/oracle/oratab file, depending on your operating system
  • The path specified by the ORACLE_HOME environment variable

The installation is about the same as the original installation. This is the Oracle home screen, in which you should select the oracle home you created with the original installation: oradbinstall09.jpg
There is also a root.sh post installation script:

Errors Patchset

During the installation I also got this error:

Oracle Universal Installer has detected that
there are processes running in the
currently selected Oracle Home. The
following processes need to be shutdown
before continuing:
java

There are some unpublished bug reports about is, I can't find the original bug reports:

11.1.0.7 OUI FAILS TO DETECT RUNNING PROCESSES CORRECTLY ON AIX 6.1 ML 4 SP1
APPLYING 10.1.2.3 PATCHSET FAILS WITH “THE FOLLOWING PROCESSES NEED TO SHUTDOWN BEFORE CONTINUING: JAVA”

The solution is, as root user, before the installation is started:

cd /usr/sbin/
mv fuser fuser.orig
touch /usr/sbin/fuser
chmod +x /usr/sbin/fuser

Undo the change after the installation is done.

Oracle Profile

Create or edit the oracle .profile file:

# Set the path
PATH=/usr/bin:/etc:/usr/sbin:/usr/ucb:$HOME/bin:/usr/bin/X11:/sbin:/opt/oracle/product/10.2/bin:.

# Set oracle environment

export PATH ORACLE_BASE ORACLE_HOME CLASSPATH LD_LIBRARY_PATH ORACLE_OWNER ORA_NLS33 TNS_ADMIN ORACLE_SID HOST PS1 ENV

if [ -s "$MAIL" ]           # This is at Shell startup.  In normal
then echo "$MAILMSG"        # operation, the Shell checks
fi                          # periodically.

Note that the ORACLE_SID has to be set after the database/instance has been created.
