RH6 installation Oracle11g+asm

Installation steps I skipped here, mainly on the installation process encountered problems or important steps:

1. Udev binding:

For i in B c D e;
Do
echo "kernel==\" sd*\ ", bus==\" scsi\ ", program==\"/sbin/scsi_id--whitelisted--replace-whitespace--device=/dev/\$ Name\ ", result==\" '/sbin/scsi_id--whitelisted--replace-whitespace--device=/dev/sd$i ' \ ", NAME=\" asm-disk$i\ ", Owner=\ "grid\", group=\ "asmadmin\", mode=\ "0660\" ">>/etc/udev/rules.d/99-oracle-asmdevices.rules
Done

2, RH6 installation 11.2.1.0 version Execution root.sh Error resolution (this is the 11.2.1.0 bug Doc ID 1557677.1):
Today, someone in the QQ group asked this question, hi configured Oracle Grid Infrastructure for a Standalone Server (11.2. 0.1) on RHEL 6.4,restarting the server Oracle-has not starts and shows the next Ohas error:

# Crsctl Start has
Crs-4124:oracle High Availability Services startup failed.
Crs-4000:command Start failed, or completed with errors.

# CRSCTL Check has
Crs-4639:could not contacted Oracle high availability Services

Cause
======================================
The root cause is because the Oracle Grid infrastructure 11.2.0.1 does do support rel 6,we can use the Rel 6 compatible V Ersion 11.2.0.3 and higher

Solution
======================================
[Email protected] ~]$ Ps-ef | grep INIT.OHASD
Grid 8203 0 18:47 pts/0 00:00:00 grep init.ohasd

INIT.OHASD is used to control OHASD (which runs as a binary ' Ohasd.bin '). If INIT.OHASD is not running OHASD won ' t being able to start.

Cat/etc/inittab|grep INIT.OHASD

[Email protected] has]$ Cat/etc/inittab|grep INIT.OHASD
H1:35:RESPAWN:/ETC/INIT.D/INIT.OHASD Run >/dev/null 2>&1

Manually Start INIT.OHASD

#/etc/init.d/init.ohasd start
Or
#/sbin/init Q

# CRSCTL Check has
Crs-4638:oracle High Availability Services is online

Other ways:

In RHEL 6 inittab is no longer supported, it uses upstart insted.
See more info in page:http://searchenterpriselinux.techtarget.com/tip/ Rhel-6-ditches-system-v-init-for-upstart-what-linux-admins-need-to-know

To solve the issue do the following:
Create the file:/etc/init/init-oracle.conf

* #start oracle*
Start on RunLevel [0123456]
Stop on RunLevel [016]

Respawn
EXEC/ETC/INIT.D/INIT.OHASD Run >/dev/null 2>&1
After the file is created, reboot and Oracle should start normaly

Or

Problem is indeed because of upstart/init incompatibility. Here is the working to:
1) Proceed with the installation as usual until root.sh invocation.
2) before root.sh edit $GRID _home/crs/install/s_crsconfig_lib.pm, go to line 1173 (you should find a code like:if ($srv E Q "OHASD") {# Start OHASD).
3) Insert a following snippet before starting OHASD part (line 1173)

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;
}
4) Create a file/etc/init/oracle-ohasd.conf with the following content inside

# Oracle OHASD Startup

Start on RunLevel [35]
Stop on RunLevel [!35]
Respawn
EXEC/ETC/INIT.D/INIT.OHASD Run >/dev/null 2>&1
5) Invoke root.sh
6) Finish the installation.

If you previously ran root.sh (not successfully), simply rolled it back:
$GRID _home/crs/install/roothas.pl-deconfig-force-verbose
Make changes above and continue.

unsupported:11.2.0.1/11.2.0.2 GI root.sh fails on ol6/rhel6 with OHASD failed to start:inappropriate IOCTL for device (D OC ID 1557677.1)

3. DBCA The ASM disk is not found during installation of Oracle software because Oracle file permissions are incorrect, perform chmod +s Oracle or chmod 6751 Oracle Solution
Cd/u01/app/oracle/product/grid/bin
[[email protected] bin]$ ll Oracle
-rwsrwsr-x 1 grid oinstall 203972923 June 22:20 Oracle

The main is the directory is not well planned, resulting in later to modify the directory permissions.
When installing GI, remember not to put $ORACLE _base and $oracle_home directory has a parent-child directory relationship.
