CentOS系统as4.6如何安装oracle10.2.0.1
CentOS系统as4.6如何安装oracle10.2.0.1，针对这个问题，这篇文章详细介绍了相对应的分析和解答，希望可以帮助更多想解决这个问题的小伙伴找到更简单易行的方法。
在CentOS系统 as4.6 安装oracle 10.2.0.1之前，我们应先对Centos系统进行安装。要对于Centos安装不多做说明一般开发工具都要装。安装完还需要安装补丁包sysstat-5.0.5-14.rhel4.i386.rpm 和 libaio-0.3.105-2.i386.rpm 即可。
CentOS系统创建oracle账号
su - root
groupadd dba
groupadd oinstall
useradd -c oracle -g dba -G oinstall oracle
passwd oracle
CentOS系统创建oralce安装目录
su - root
mkdir -p /u01/app/oracle
chown -R oracle.dba /u01
mkdir /var/opt/oracle
chown oracle.oinstall /var/opt/oracle
chmod 755 /var/opt/oracle
1.修改/etc/sysctl.conf 文件，增加如下内容：
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 = 262144 net.core.rmem_max = 262144 net.core.wmem_default = 262144 net.core.wmem_max = 262144
sem 4 个参数依次为 SEMMSL(每个用户拥有信号量***数)；SEMMNS(系统信号量***数)；
SEMOPM(每次 semopm 系统调用操作数)；SEMMNI(系统辛苦量集数***数).
shmmax ***共享内存 2GB 物理内存如果小的话可以设置成 536870912.
shmmni 最小共享内存 4096KB.
shmall 所有内存大小.
运行/sbin/sysctl -p设置核心参数
2.修改/etc/security/limits.conf加入
oraclesoft nproc2047
oraclehard nproc16384
oraclesoft nofile 1024
oraclehard nofile 65536
3.修改/etc/pam.d/login ，加入
session required pam_limits.so
4.修改/etc/profile ，加入
if [ $USER = "oracle" ]; then if [ $SHELL = "/bin/ksh" ]; then ulimit -p 16384 ulimit -n 65536 else ulimit -u 16384 -n 65536 fi fi
5.oracle登录 修改.bash_profile
# .bash_profile # Get the aliases and functions if [ -f ~/.bashrc ]; then . ~/.bashrc fi # User specific environment and startup programs PATH=$PATH:$HOME/bin
export PATH unset USERNAME # Set the LD_ASSUME_KERNEL environment variable only for Red Hat 9, # RHEL AS 3, and RHEL AS 4 !! # Use the "Linuxthreads with floating stacks" implementation instead of NPTL: export LD_ASSUME_KERNEL=2.6.9-55.EL # for RHEL AS 4 # Oracle Environment export ORACLE_BASE=/u01/app/oracle export ORACLE_HOME=$ORACLE_BASE/product/10.0.2/db_1 export ORACLE_SID=your'sSID # export TNS_ADMIN= Set if sqlnet.ora, tnsnames.ora, etc. are not in $ORACLE_HOME/network/admin export NLS_LANG=American_America.UTF8; export ORA_NLS33=$ORACLE_HOME/ocommon/nls/admin/data LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib export LD_LIBRARY_PATH # Set shell search paths export PATH=$PATH:$ORACLE_HOME/bin
6.修改 /etc/oratab 文件
修改$ORACLE_HOME dbstart
$ cd $ORACLE_HOME/dbs $ sqlplus /nolog SQL>connect / as sysdba connected SQL>Create pfile from spfile
dbora内容
# Set ORA_HOME to be equivalent to the ORACLE_HOME # from which you wish to execute dbstart and # dbshut # set ORA_OWNER to the user id of the owner of the # Oracle database in ORA_HOME ORA_HOME=/u01/app/oracle/product/10.0.2/db_1 ORA_OWNER=oracle case "$1" in 'start_msg') echo"startup oracle10g database and listener" ;; 'stop_msg') echo "shutdown oracle10g database and listener" ;; 'start') # Start the Oracle database: su - $ORA_OWNER -c $ORA_HOME/bin/dbstart # start the Oracle dbconsole: ;; 'stop') # Stop the Oracle database: su - $ORA_OWNER -c "emctl stop dbconsole" su - $ORA_OWNER -c $ORA_HOME/bin/dbshut # Stop the Oracle listener: su - $ORA_OWNER -c "lsnrctl stop listener" ;; esac 1#cp dbora /etc/init.d 2#cd /etc/init.d 3#chmod 777 dbora 4#cd rc2.d #ln -s ../init.d/dbora S80ora 5#cd ../rc3.d #ln -s ../init.d/dbora S80ora 6#cd ../rc0.d #ln -s ../init.d/dbora K80ora 7#cd ../rc4.d #ln -s ../init.d/dbora S80ora #ln -s ../init.d/dbora K80ora 8#cd ../rc5.d #ln -s ../init.d/dbora S80ora #ln -s ../init.d/dbora K80ora
