CentOS 6.8에 preinstall후 Oracle ASM 설정하기
1. 그룹 및 사용자 추가
$ su
Password:
# groupadd asmadmin
# groupadd asmdba
# groupadd asmoper
# useradd -g oinstall -G dba,asmadmin,asmdba,asmoper -d /home/grid grid
# passwd grid
Changing password for user grid.
New password: *****
Retype new password: *****
passwd: all authentication tokens updated successfully.
# mkdir -p /u01/app/grid
# chown -R grid:oinstall /u01/app/grid
# usermod -g oinstall -G dba,asmdba oracle
2. Security 설정
# cat >> /etc/pam.d/login <<EOF
session required pam_limits.so
EOF
# vi /etc/security/limits.conf
#oracle soft nproc 2047
#oracle hard nproc 16384
#oracle soft nofile 1024
#oracle hard nofile 65536
grid soft nproc 2047
grid hard nproc 16384
grid soft nofile 1024
grid hard nofile 65536
# cat >> /etc/profile <<EOF
if [ \$USER = "oracle" ] || [ \$USER = "grid" ]; then
if [ \$SHELL = "/bin/ksh" ]; then
ulimit -p 16384
ulimit -n 65536
else
ulimit -u 16384 -n 65536
fi
umask 022
fi
EOF
# cat >> /etc/csh.login <<EOF
if ( \$USER == "oracle" || \$USER == "grid" )
then
limit maxproc 16384
limit descriptors 65536
endif
EOF
3. 오라클 Grid 설치를 위한 환경설정
# su - grid
$ vi .bash_profile
.bash_profile
# Get the aliases and functions
if [ -f ~/.bashrc ]; then
. ~/.bashrc
fi
# User specific environment and startup programs
PATH=$PATH:$HOME/bin
export PATH
# Oracle Configuration
ORACLE_SID=+ASM; export ORACLE_SID
ORACLE_BASE=/u01/app/grid; export ORACLE_BASE
ORACLE_HOME=$ORACLE_BASE/product/11.2.0/grid; export ORACLE_HOME
PATH=$PATH:$ORACLE_HOME/bin; export PATH
LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib; export LD_LIBRARY_PATH
CLASSPATH=:$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib:$ORACLE_HOME/network/jlib
export CLASSPATH
4. VMWare Guest OS instance에 HDD를 추가

8. Configure oracle asm library driver
# oracleasm configure -i
Configuring the Oracle ASM library driver.
This will configure the on-boot properties of the Oracle ASM library
driver. The following questions will determine whether the driver is
loaded on boot and what permissions it will have. The current values
will be shown in brackets ('[]'). Hitting <ENTER> without typing an
answer will keep that current value. Ctrl-C will abort.
Default user to own the driver interface []: grid
Default group to own the driver interface []: dba
Start Oracle ASM library driver on boot (y/n) [n]: y
Scan for Oracle ASM disks on boot (y/n) [y]: y

Changes will remain in memory only, until you decide to write them.
After that, of course, the previous content won't be recoverable.
Warning: invalid flag 0x0000 of partition table 4 will be corrected by w(rite)
WARNING: DOS-compatible mode is deprecated. It's strongly recommended to
switch off the mode (command 'c') and change display units to
sectors (command 'u').

crs-4124 oracle high availability services startup failed error
1.If you previously ran root.sh (not successfully), simply roll it back:
# /u01/app/grid/product/11.2.0/grid/crs/install/roothas.pl -deconfig -force -verbose
2.edit $GRID_HOME/crs/install/s_crsconfig_lib.pm ( add the following command before # Start OHASD )
# vi /u01/app/grid/product/11.2.0/grid/crs/install/s_crsconfig_lib.pm
my $UPSTART_OHASD_SERVICE = "oracle-ohasd";
my $INITCTL = "/sbin/initctl";
($status, @output) = system_cmd_capture ("$INITCTL start $UPSTART_OHASD_SERVICE");
if (0 != $status)
{
error ("Failed to start $UPSTART_OHASD_SERVICE, error: $!");
return $FAILED;
}
3. Create a file /etc/init/oracle-ohasd.conf
# vi /etc/init/oracle-ohasd.conf
# Oracle OHASD startup
start on runlevel [35]
stop on runlevel [!35]
respawn
exec /etc/init.d/init.ohasd run >/dev/null 2>&1
4.run the root.sh again then finish installation.
