执行dbstart启动数据库时报错
Failed to auto-start Oracle Net Listene using /ade/vikrkuma_new/oracle/bin/tnslsnr
看来是listener服务没有��h��Q�但是执行lsnrctl start却能启动listener服务�?br />搜烦dbstart文�g中的tnslsnr字符�?br />
grep tnslsnr dbstart

�q�回�l�果:
if [ -f $ORACLE_HOME_LISTNER/bin/tnslsnr ] ; then
    echo "Failed to auto-start Oracle Net Listene using $ORACLE_HOME_LISTNER/bin/tnslsnr"

看来可能是ORACLE_HOME_LISTNER环境变量引�v的，查找 ORACLE_HOME_LISTNER

grep ORACLE_HOME_LISTNER dbstart

�q�回�l�果
# 3) Set ORACLE_HOME_LISTNER
ORACLE_HOME_LISTNER=/ade/vikrkuma_new/oracle
if [ ! $ORACLE_HOME_LISTNER ] ; then
echo "ORACLE_HOME_LISTNER is not SET, unable to auto-start Oracle Net Listener"
LOG=$ORACLE_HOME_LISTNER/listener.log
if [ -f $ORACLE_HOME_LISTNER/bin/tnslsnr ] ; then
    $ORACLE_HOME_LISTNER/bin/lsnrctl start >> $LOG 2>&1 &
    export VER10LIST=`$ORACLE_HOME_LISTNER/bin/lsnrctl version | grep "LSNRCTL for " | cut -d' ' -f5 | cut -d'.' -f1`
    echo "Failed to auto-start Oracle Net Listene using $ORACLE_HOME_LISTNER/bin/tnslsnr"
        $LOGMSG "Restart Oracle Net Listener using an alternate ORACLE_HOME_LISTNER: lsnrctl start"

其中有一�D늻�ORACLE_HOME_LISTNER环境变量赋��|��但是�q�个路径是不对的�Q�编辑dbstart文�g
vi dbstar
��该行改�?font color="#ff0000">export ORACLE_HOME_LISTNER=$ORACLE_HOME
保存退出，然后执行dbstart��没问题了。呵�?br />
想系�l�启动是自动启动数据库可以通过修改/etc/rc.d/rc.local文�g
一开始我写的命��o�?
su oracle -c ora_App/product/10.2.0/db_1/bin/lsnrctl start
su oracle -c ora_App/product/10.2.0/db_1/bin/dbstart
但是su oracle -c ora_App/product/10.2.0/db_1/bin/lsnrctl start是参数start不�v作用�Q�它�q�入了lsnrctl命��o提示�W�，�q�没有启动，后来把命令用双引号引��h��可以了如下�Q?br />su oracle -c "ora_App/product/10.2.0/db_1/bin/lsnrctl start"
是可以启动了�Q�但是启动时报错如下:
Message 1053 not found; No message file for product=network, facility=TNSTNS-12541: Message 12541 not found; No message file for product=network, facility=TNS
TNS-12560: Message 12560 not found; No message file for product=network, facility=TNS
但是如果我用oracle用户登陆执行lsnrctl start��׃��报错�Q�看来是在root用户中执行su oracle -c "ora_App/product/10.2.0/db_1/bin/lsnrctl start"有些Oracle环境变量没有讄��。查了一下su 命��o的参敎ͼ�其中有个-l参数
-.-l�?-login 　改变�w�䆾�Ӟ��也同时变更工作目录，以及HOME,SHELL,USER,LOGNAME。此外，也会变更PATH变量�?
加上参数
su oracle -lc "ora_App/product/10.2.0/db_1/bin/lsnrctl start"

Install VirtualBox Guest Additions in CentOS (RedHat) Linux Guest

Install VirtualBox Guest Additions in CentOS (RedHat) Linux Guest

When you try to install the VirtualBox Guest Additions for a Linux guest system, this will fail due to some weired ‘features’ in the installation. This post is based on my experience with VirtualBox 3.0.6.

To perform the installation do the following:
Choose Install Guest Additions... from the VirtualBox menu. Open a terminal window in your guest system. Do a

cd /media/VBOXADDITIONS_3.0.6_52128/
(the foldername will change depending on the VBox version). Proceed as described below.

1. Cannot execute .run file

When you try to execute the installation file (e.g. VBoxLinuxAdditions-amd64.run), you get an error message like this

[root@integration /]# cd /media/VBOXADDITIONS_3.0.6_52128/

[root@integration VBOXADDITIONS_3.0.6_52128]# ./VBoxLinuxAdditions-amd64.run

-bash: ./VBoxLinuxAdditions-amd64.run: /bin/sh: bad interpreter: Permission denied

The solution is to use the command

sh VBoxLinuxAdditions-amd64.run

instead (choosing the right architecture, it was 64bit in this case).

2. Installer complains about missing gcc and Linux kernel headers

The solution to this is to update your kernel to the latest version and install headers and sources for it. VirtualBox requires to compile some drivers when it installs.

Just execute
yum update kernel yum install gcc yum install kernel-devel
.
Run the installer again and everything should be ok.
