昨天晚上看到盖总的微信里发布12.2.0.1版本开放下载了，于是立马登上edelivery去下载，现在只开放了Linux 64位版的。

今天就测试了一下12.2.0.1的rhel7.2上的安装。

总体的安装步骤跟12.1版本中没有太大的区别下面只列出了简单的配置和安装步骤

1、修改主机名和配置/etc/hosts

2、安装依赖包

参考了12.2的官方文档，现在只提供Oracle Linux上的依赖包，但是手头没有OEL7.2，于是选择了RHEL7.2，没有太多的差别

yum install -y binutils*

yum install -y compat-libcap1*

yum install -y compat-libstdc++*

yum install -y glibc*

yum install -y glibc-devel*

yum install -y ksh*

yum install -y libX11*

yum install -y libXau*

yum install -y libXi*

yum install -y libXtst*

yum install -y libaio*

yum install -y libaio-devel*

yum install -y libgcc*

yum install -y libstdc++*

yum install -y libstdc++-devel*

yum install -y libxcb*

yum install -y make*

yum install -y net-tools*

yum install -y nfs-utils*

yum install -y smartmontools*

yum install -y sysstat*

yum install -y unixODBC*

yum install -y binutils*686*

yum install -y compat-libcap1*686*

yum install -y compat-libstdc++*686*

yum install -y glibc*686*

yum install -y glibc-devel*686*

yum install -y ksh*686*

yum install -y libX11*686*

yum install -y libXau*686*

yum install -y libXi*686*

yum install -y libXtst*686*

yum install -y libaio*686*

yum install -y libaio-devel*686*

yum install -y libgcc*686*

yum install -y libstdc++*686*

yum install -y libstdc++-devel*686*

yum install -y libxcb*686*

yum install -y make*686*

yum install -y net-tools*686*

yum install -y nfs-utils*686*

yum install -y smartmontools*686*

yum install -y sysstat*686*

yum install -y unixODBC*686*

3、配置内核参数

vi /etc/sysctl.conf

fs.aio-max-nr = 1048576

fs.file-max = 6815744

kernel.shmall = 2097152

kernel.shmmax = 4294967295

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 = 1048576

systemctl -p 应用修改

4、创建oracle用户和用户组及创建目录

groupadd -g 5001 oinstall

groupadd -g 5002 dba

useradd -g oinstall -G dba -u 5001 oracle

passwd oracle

mkdir -p /u01/app/oracle/product/12.2/db1

chown oracle:oinstall -R /u01

5、修改Oracle用户的系统限制

vi /etc/security/limits.conf

oracle soft nofile 1024

oracle hard nofile 65536

oracle soft nproc  2047

oracle hard nproc  16384

oracle soft stack  10240

oracle hard stack  32786

6、修改oracle用户的.bash_profile

vi /home/oracle/.bash_profile

export ORACLE_BASE=/u01/app/oracle

export ORACLE_HOME=$ORACLE_BASE/product/12.2/db1

export ORACLE_SID=orcl

export PATH=$ORACLE_HOME/bin:$PATH

7、安装数据库软件

./runInstall

执行root.sh

8、创建数据库

在使用dbca创建包含CDB和PDB的数据库时报了好几次错，都莫名其妙的，比如：

Error while executing "/u01/app/oracle/product/12.2/db1/rdbms/admin/execemx.sql". Refer to "/u01/app/oracle/cfgtoollogs/dbca/orcl/execemx0.log"

查看log日志文件里是空的

还有ORA-00600: internal error code, arguments: [kcrf_make_redokey], [18446744073709551615], [], [], [], [], [], [], [], [], [], []

查了MOS上没有关于12.2的文档

于是想到了只不创建CDB的数据库是否还报错，结果正常创建成功。

后来与同事讨论，他提到了手工创建数据库是否有问题呢，于是尝试手工创建包含CDB和PDB的数据库。

手动创建数据库简略步骤：

1、创建pfile

db_name=orcl

enabled_pluggable_database=true #要创建CDB/PDB数据库必须有这个参数

control_files='/u01/app/oracle/oradata/orcl/control01.ctl'

2、创建spfile

create spfile from pfile;

3、执行CREATE DATABASE语句

CREATE DATABASE orcl

USER SYS IDENTIFIED BY oracle

USER SYSTEM IDENTIFIED BY oracle

LOGFILE GROUP 1 ('/u01/app/oracle/oradata/orcl/redo01a.log') SIZE 100M BLOCKSIZE 512,

GROUP 2 ('/u01/app/oracle/oradata/orcl/redo02a.log') SIZE 100M BLOCKSIZE 512,

GROUP 3 ('/u01/app/oracle/oradata/orcl/redo03a.log') SIZE 100M BLOCKSIZE 512

MAXLOGHISTORY 1

MAXLOGFILES 16

MAXLOGMEMBERS 3

MAXDATAFILES 1024

CHARACTER SET ZHS16GBK

NATIONAL CHARACTER SET AL16UTF16

EXTENT MANAGEMENT LOCAL

DATAFILE '/u01/app/oracle/oradata/orcl/cdb/system.dbf'

SIZE 700M REUSE AUTOEXTEND ON NEXT 10240K MAXSIZE UNLIMITED

SYSAUX DATAFILE '/u01/app/oracle/oradata/orcl/cdb/sysaux.dbf'

SIZE 550M REUSE AUTOEXTEND ON NEXT 10240K MAXSIZE UNLIMITED

DEFAULT TEMPORARY TABLESPACE tempts1

TEMPFILE '/u01/app/oracle/oradata/orcl/cdb/temp.dbf'

SIZE 20M REUSE AUTOEXTEND ON NEXT 640K MAXSIZE UNLIMITED

UNDO TABLESPACE undotbs1

DATAFILE '/u01/app/oracle/oradata/orcl/cdb/undo.dbf'

SIZE 200M REUSE AUTOEXTEND ON NEXT 5120K MAXSIZE UNLIMITED

ENABLE PLUGGABLE DATABASE

SEED

FILE_NAME_CONVERT=('/u01/app/oracle/oradata/orcl/cdb/','/u01/app/oracle/oradata/orcl/seed/') 

SYSTEM DATAFILES size 125M autoextend on next 10M maxsize unlimited

SYSAUX DATAFILES size 100M autoextend on next 10M maxsize unlimited;

4、执行创建数据字典脚本

1)In SQL*Plus, connect to your Oracle Database instance with the SYSDBA administrative privilege:

@?/rdbms/admin/catalog.sql

@?/rdbms/admin/catproc.sql

@?/rdbms/admin/utlrp.sql

2)In SQL*Plus, connect to your Oracle Database instance as SYSTEM user:

@?/sqlplus/admin/pupbld.sql

到此创建完成。

整体过程与12.1版本的安装没有多大的区别，就是在dbca时报的错很奇怪。
