Oracle10g安装中遇到的错误及解决办法

linux解决xhost: unable to open display
实用技巧：在Linux下设置xhost方法步骤

第一步：用root登陆linux，启动vnc服务；
第二步：根据vnc起来的端口，设置export DISPLAY=localhost:1（1表示vnc在第一个tty上启动的），vnc的启动信息见附件1；
第三步：执行xhost +，并且提示“access control disabled, clients can connect from any host”才正确。

linux下的操作日志如下：
[root@localhost ~]# vncserver
New 'localhost:1 (root)' desktop is localhost:1
Starting applications specified in /root/.vnc/xstartupLog file is /root/.vnc/localhost:1.log
[root@localhost ~]# export DISPLAY=localhost:1
[root@localhost ~]# xhost +
access control disabled, clients can connect from any host
在设置xhost时，出现了unable的问题。使用上诉方法就可以搞定。

遇到类似问题，常用的解决方法是在root用户下:
  [root] export DISPLAY=:0 或export DISPLAY=192.168.1.1:0.0或export DISPLAY=localhost:10.0
然后：
   [root] xhost +
通常这样做就可以了，但有时候还是不行，那就要检查X11所需的依赖包是否安装完整，以下3个包必须有。
   [root] rpm -qa |grep X11
     libX11-common-1.5.0-4.el6.noarch
     libX11-1.5.0-4.el6.x86_64
     libX11-devel-1.5.0-4.el6.x86_64

Problem: The kernel parameters do not meet the minimum requirements (see above).
Recommendation: Perform operating system specific instructions to update the kernel parameters.
=======================================================================

解决办法：

root，在/etc/sysctl.conf中，更改内核参数。

让更改生效，重启或执行命令sysctl –p

更改后相关参数：

# Kernel sysctl configuration file for Red Hat Linux
#
# For binary values, 0 is disabled, 1 is enabled.  See sysctl(8) and
# sysctl.conf(5) for more details.

# Controls IP packet forwarding
net.ipv4.ip_forward = 0

# Controls source route verification
net.ipv4.conf.default.rp_filter = 1

# Do not accept source routing
net.ipv4.conf.default.accept_source_route = 0

# Controls the System Request debugging functionality of the kernel
kernel.sysrq = 0

# Controls whether core dumps will append the PID to the core filename.
# Useful for debugging multi-threaded applications.
kernel.core_uses_pid = 1

kernel.shmall = 2097152
kernel.shmmax = 2147483648
kernel.shmmni = 4096
kernel.sem = 250 32000 100 128
fs.file-max = 65536
net.ipv4.ip_local_port_range =1024 65000
net.core.rmem_default = 4194304
net.core.rmem_max = 4194304
net.core.wmem_default = 262144
net.core.wmem_max = 262144

=======================================================================

Checking available swap space requirements ...
Expected result: 2652MB
Actual Result: 1983MB
Check complete. The overall result of this check is: Failed <<<<
Problem: The system does not have the required swap space.
Recommendation: Make more swap space available to perform the install.
=======================================================================

解决办法：

增大swap大小。
Expected result:2652MB
Actual Result:1983MB

增大1024M即可满足要求

具体操作：

#此时需要改变交换区的大小

#注：交换区大小建议调整为实际内存大小的2倍

（第一步：使用free -m查看目前swap的交换空间情况，1019M，也可以使用grep SwapTotal /proc/meminfo查看）

[root@localhost swapimage]# free -m

total used free shared buffers cached

Mem: 1010 995 15 0 1 847

-/+ buffers/cache: 145 865

Swap: 1019 0 1019

（用df –h查看磁盘空间的使用情况）

[root@localhost ~]# df -h

Filesystem Size Used Avail Use% Mounted on

/dev/sda2 3.8G 3.1G 572M 85% /

/dev/sda3 15G 1.7G 13G 13% /home

/dev/sda1 46M 11M 33M 25% /boot

tmpfs 506M 0 506M 0% /dev/shm

（第二步：确保系统中有足够的空间用来做swap交换空间，经过df –h查看，只有/home下面还有13G的空间是比较大的，所以我这边准备在/home/swapimage开辟swap交换区）

[root@localhost home]# mkdir swapimage（在/home目录下创建swapimage文件夹）

[root@localhost home]# cd swapimage/ （进入swapimage文件夹）

[root@localhost swapimage]# dd if=/dev/zero f=/home/swapimage/swap bs=1024count=1024000（添加交换文件并设置大小为1G）

1024000+0 records in

1024000+0 records out

1048576000 bytes (1.0 GB) copied, 16.2007 seconds, 64.7 MB/s

（再次用df –h查看磁盘空间的使用情况，/home的可以大小已经由13G变成12G了，也就是说通过上面的dd操作，我们已经成功的分配了1G的swap交换空间）

[root@localhost swapimage]# df -h

Filesystem Size Used Avail Use% Mounted on

/dev/sda2 3.8G 3.1G 572M 85% /

/dev/sda3 15G 2.7G 12G 20% /home

/dev/sda1 46M 11M 33M 25% /boot

tmpfs 506M 0 506M 0% /dev/shm

（第三步：使用mkswap命令，创建（或设置）交换空间）

[root@localhost swapimage]# mkswap /home/swapimage/swap

Setting up swapspace version 1, size = 1048571 kB

（第四步：使用swapon命令，启用新增的1G交换空间）

[root@localhost swapimage]# swapon /home/swapimage/swap

（使用free –m确认新增的swap交换空间已生效，2019）

[root@localhost swapimage]# free -m

total used free shared buffers cached

Mem: 1010 997 13 0 2 848

-/+ buffers/cache: 146 864

Swap: 2019 0 2019

（第五步：修改/etc/fstab文件，使新增的1G交换空间在系统重启后自动生效）

[root@localhost swapimage]# vi /etc/fstab

/home/swapimage/swap swap swap defaults 0 0

Checking Network Configuration requirements ...
Check complete. The overall result of this check is: Not executed <<<<
Recommendation: Oracle supports installations on systems with DHCP-assigned public IP addresses.  However, the primary network interface on the system should be configured with a static IP address in order for the Oracle Software to function properly.  See the Installation Guide for more details on installing the software on systems configured with DHCP.
=======================================================================

（解决方案：切换到root用户，进行静态IP地址的配置

[oracle@localhost database]$ vi /etc/sysconfig/network-scripts/ifcfg-eth0

# Advanced Micro Devices [AMD] 79c970 [PCnet32 LANCE]

DEVICE=eth0

#BOOTPROTO=dhcp

BOOTPROTO=static

IPADDR=192.168.1.289

NETMASK=255.255.255.0

GATEWAY=192.168.1.1

#HWADDR=00:0c:29:c9:31:a9

ONBOOT=yes

TYPE=Ethernet

（重启使IP地址生效）

方法1：

/sbin/ifdown eth0

/sbin/ifup eth0

方法2：

service network restart

（设置好静态IP地址后retry，还是Not executed，搜索到资料讲需要修改/etc/hosts文件，将127.0.0.1修改为192.168.1.289（也就是设置的静态IP地址））

[oracle@localhost database]$ su root

Password:

[root@localhost database]# vi /etc/hosts

（修改后retry检查，通过passed）

）

如果 固定IP是已经配置好的，仍然提示DHCP的问题，可能是/etc/hosts文件配置错误。

需要检查/etc/hosts文件，确认hosts文件中的本地地址配置与实际是否符合。
