I thought that I was not in touch with the host recently, but was willing to violate this. I had to integrate the client host again.

I. Platform Overview

HP prolient ml570 G4
<Http://h50025.www5.hp.com/hpcom/cn_cn/8_1_80_5525summary.html>
Bare metal environment with 16 gb mem, 4 CPU, 12*146 GB SCSI
Install enterprise RedHat Linux as 4
Install oracle92 Database Service

Ii. Raid Division

Hard Disk is divided by RAID 5 + 1spare. <raid series introduction http://blog.csdn.net/liwei_cmg/archive/2007/04/10/1559562.aspx>
Method 1: when the system starts, when the raid array card self-check occurs, press the control key (prompt) to enter the array card
BiOS Division
Method 2: Use the built-in smart disc for configuration Division (Note: The software version of smart is the main concern, instead
Must be compatible with the host Model)

The partitioning of disk arrays is relatively simple. Pay attention to the following points:

1. When RAID5 is used to keep idle disks, pay attention to enabling auto rebuild. When a hard disk fails
The system automatically uses the idle disk for reconstruction.
2. Riad needs to specify the stripe size for online transaction processing. Generally, it is set to about 32 kb for file system processing.
You can set a value larger than kb.

Iii. System Installation

About system installation in previous articles and introduction Only common problems are listed here.

Problem 1. RedHat Enterprise Edition 4 installation disks provided by other hosts cannot find SCSI Array cards

Reason: the built-in CD cannot be used universally. Please use genuine

Problem 2: After the copy file is successfully installed, restart. If the hard disk is set to the first boot sequence, the system crashes. As shown in
If you set the hard disk to another boot sequence, the following message is displayed: grub loding stage2...

Cause: the grub boot is damaged. At this time, the normal restoration of the CD is also invalid. Start with Red Hat Linux
Press enter in Linux Rescure under boot, load the image, and a prompt appears. There are two methods in principle.

(Method 1)
A. # chroot/mnt/sysimage
B. # fdisk-l find the primary boot partition of the hard disk. Here is/dev/CCISS/c0d0p1.
C. # grub-install/dev/CCISS/c0d0p1
D. # shutdown/reboot

(Method 2)
A. # chroot/mnt/sysimage
B. # grub
C. Grub> Find/boot/GRUB/stage1
D. Grub> Find/boot/GRUB/stage2 stage1 and 2 Both indicate (hd0, 0)
E. Grub> root (hd0, 0)
F. Grub> setup (hd0)
G. Grub> quit
H. # shutdown/reboot

This method is invalid when method 2 is used on the local machine. method 1 is used to solve the problem, but a new problem occurs.

Problem 3: Uncompressing Linux... OK, booting the kernel.

Cause: this error is not a grub error. The possible cause is the kernel you are using or the compiled kernel.
It uses ACPI or other similar functions, but it does not work properly. It can be disable in BIOS.
Or add no ACPI and other parameters to the startup kernel. This machine uses the APCI feature in BIOS to troubleshoot the problem.

Problem 4: No optical fiber indicator is reported. Check that the corresponding VLAN port is down.

Cause: there is a small white problem. optical fiber cables need to be cross-connected.

Iv. System Configuration

After the operating system is successfully installed, configure the service and install the software.

Problem 1: the IP address of the NIC is correctly configured. The optical fiber is connected and cannot be pinged.

Cause: the local machine contains two common NICs, both of which are activated. In normal cases, it cannot be redundant.
For switchover, special software must be installed. You only need to activate a network card.

Problem 2. error message about smbmount

Timeout connecting to 134.98.83.123: 445
Timeout connecting to 134.98.83.123: 139
Error connecting to 134.98.83.123 (operation already in progress)
7991: connection to micropc failed
SMB connection failed

Cause: the firewall has disabled the port. If the password contains characters such as. During mount, you can use the password
.

Problem 3. After gdmconfig is configured, the prompt "cocould not look up Internet address for loaclhost. localdomain." appears.
This will prevent gnome from operation correctly. It may be possible to correct the problem
Adding localhost. localdomain to the file/etc/hosts.

Cause: Add 127.0.0.1 localhost. localdomain localhost in/etc/hosts as prompted.
Localhost. localdomain is the host name and can be changed.

Problem 4. After useradd, you cannot log on

Cause: Use passwd <User Name> to change the password under the root user.


V. Database Configuration and Data Import

Oracle Installation problems have been mentioned in many articles in the previous series. This time it went very smoothly without any errors.
Virtual Machine redhatlinux9 installation oralce92 whole process (link: http://blog.csdn.net/liwei_cmg/archive/2006/05/28/759286.aspx)
Starting from server build (4). install and configure Oracle under Linux (link: http://blog.csdn.net/liwei_cmg/archive/2007/04/18/1568923.aspx)

However, we recommend that you do not use the compress option (compress = No) for data import and export. Otherwise
Large tables are slow.
