Linux平台Oracle 11g单实例 安装部署配置 快速参考
Linux平台Oracle 11g单实例 安装部署配置 快速参考
1.重建主机的Oracle用户 组 统一规范 uid gid 以保证共享存储挂接或其他需求的权限规范
userdel -r oracle
groupadd -g 500 oinstall
groupadd -g 501 dba
useradd -g oinstall -G dba -u 500 oracle
#id oracle
uid=500(oracle) gid=500(oinstall) 组=500(oinstall),501(dba)
2.安装好Oracle 需要的rpm包。安装rpm依赖包
rpm -q binutils compat-libstdc++-33 elfutils-libelf elfutils-libelf-devel glibc glibc-common glibc-devel gcc- gcc-c++ libaio-devel libaio libgcc libstdc++ libstdc++-devel make sysstat unixODBC unixODBC-devel pdksh ksh
yum install binutils compat-libstdc++-33 elfutils-libelf elfutils-libelf-devel glibc glibc-common glibc-devel gcc- gcc-c++ libaio-devel libaio libgcc libstdc++ libstdc++-devel make sysstat unixODBC unixODBC-devel pdksh ksh
注:pdksh没有安装,可以忽略。安装了ksh。
yum本地源配置参考:
3.修改配置文件 /etc/security/limits.conf
oracle soft nproc 2047
oracle hard nproc 16384
oracle soft nofile 1024
oracle hard nofile 65536
oracle soft stack 10240
4.修改配置文件 /etc/sysctl.conf
fs.aio-max-nr = 1048576
fs.file-max = 6815744
kernel.shmall = 2097152
kernel.shmmax = XXXXXXXXXX //共享内存字节数(一般75%物理内存)
kernel.shmmni = 4096
kernel.sem = 250 32000 100 128
net.ipv4.ip_local_port_range = 9000 65500
net.core.rmem_default = 262144
net.core.rmem_max = 4194304
net.core.wmem_default = 262144
net.core.wmem_max = 1048586
注:重启主机或者输入命令 sysctl -p 生效当前配置
5.Oracle用户环境变量配置
export ORACLE_BASE=/u01/app/oracle
export ORACLE_HOME=/u01/app/oracle/product/11.2.0/dbhome_1
export ORACLE_SID=jingyu
export NLS_LANG="american_america.ZHS16GBK"
export NLS_DATE_FORMAT="YYYY-MM-DD HH24:Mi:SS"
export LD_LIBRARY_PATH=$ORACLE_HOME/lib
export PATH=$ORACLE_HOME/bin:$PATH
6.解压oracle软件安装包
# unzip p10404530_112030_Linux-x86-64_1of7.zip; unzip p10404530_112030_Linux-x86-64_2of7.zip
# chown -R oracle:oinstall database
7.xmanager 安装数据库软件,dbca建库,netca创建监听
如果没有图形可采用静默模式安装~ 配置response配置文件即可。
8.根据实际需要调整数据库内存
9.调整数据库参数
打开数据库归档,规划归档路径,确定db_recovery_file_dest_size大小
--调整processes和open_cursors
alter system set processes = 1500 scope=spfile;
alter system set open_cursors = 1000;
system/sysaux表空间大小;
undo表空间大小 ;
temp表空间大小;
10.迁移win平台src用户的数据
创建表空间,用户,赋权
创建dblink
SQL> create public database link jingyu connect to src identified by src using 'src_db';
$impdp src/src network_link=jingyu schemas=src remap_tablespace=USERS:DBS_D_JINGYU parallel=2 logfile=src_jingyu.log
LONG 类型的 dblink 迁移报错信息:
ORA-31679: Table data object "SRC"."SRC_WF_FLOW" has long columns, and longs can not be loaded/unloaded using a network link
这种情况采用exp导出, imp导入 这些数据行即可。
11.rman备份策略制定
rman备份策略:手工做一个数据库的全备份,,定时每周日凌晨3点 0级备份 每周三凌晨3点 1级备份 每天凌晨4点备份归档 备份窗口为7天。
为提高1级备份效率,打开block_change_tracking
SQL> alter database enable block change tracking using file '/u01/app/oracle/oradata/jingyu/block_change_tracking.dbf';
SQL> select status from v$block_change_tracking;
--确定STATUS状态为ENABLED
