FreeBSD installation failed

28.06.2013 – 14:42

Если после установки FreeBSD Вы видете:
can't work out which disk we are booting from. Guessed BIOS device 0x80 not found by probes.

То надо сделать следующее:
Award BIOS-->Main-->IDE Channel 2 Master (тот на котором висит ваш диск)-->Access Mode [Large]

Install Oracle on RHEL 6.4 x86_64

10.06.2013 – 18:07

As write this:
http://docs.oracle.com/cd/E11882_01/install.112/e24325/toc.htm

Need setup this:

[root@test mnt]# yum install binutils  compat-libcap1 compat-libstdc++-33 compat-libstdc++-33.i686 gcc gcc-c++ glibc glibc.i686 glibc-devel glibc-devel.i686 ksh libgcc libgcc.i686 libstdc++ libstdc++.i686 libstdc++-devel libstdc++-devel.i686 libaio libaio.i686 libaio-devel libaio-devel.i686 make sysstat

And this:
[root@test mnt]# yum install unixODBC unixODBC.i686 unixODBC-devel unixODBC-devel.i686
[root@test mnt]# yum install libXp.i686 libXt.i686 libXtst.i686

Then make group, user and folders:
[root@test mnt]# /usr/sbin/groupadd oinstall
[root@test mnt]# /usr/sbin/groupadd dba
[root@test mnt]# /usr/sbin/useradd -g oinstall -G dba oracle
[root@test mnt]# passwd oracle
[root@test mnt]# mkdir -p /u01/app/
[root@test mnt]# chown -R oracle:oinstall /u01/app/
[root@test mnt]# chmod -R 775 /u01/app/

Set resource configuration:
1 * 1024 * 1024 * 1024 / 4096 = 1310720 (when 1 = GB RAM)

echo “kernel.shmall = 1310720” >> /etc/sysctl.conf

Then set transfer video over IP:
On OracleHost:
export DISPLAY=adminhost:0.0  

On AdminHost:
xhost +OracleHost

Then set environment variables:
[root@test mnt]# export ORACLE_BASE=/u01/app/oracle
[root@test mnt]# export ORACLE_SID=test
