新年开工第1天,创建一个Oracle 21c数据库

作者:互联网

方法不再介绍了,需要安装Github、Vagrant和VirtualBox,然后从这里下载项目。
需要从这里下载Oracle数据库21.3介质,并存放在vagrant-projects\OracleDatabase\21.3.0目录下。

安装介质只需要数据库的,不需要GI的。也可以从My Oracle Support或edelivery下载,但最终都需要更名为LINUX.X64_213000_db_home.zip

运行以下命令开始安装,21c使用的操作系统为Oracle Linux 8,目前是8.5:

vagrant up

安装过程如下,总共耗时不到21分钟:

...
oracle-21c-vagrant: [WARNING] [DBT-11219] Maximum of memory percentage (105) is allocated for the database creation, which might lead to  "ORA-00700: SOFT INTERNAL ERROR" during database creation.
    oracle-21c-vagrant:    CAUSE: Sum of sga and 2*pga is equal to or exceeding 90% of total physical memory.
    oracle-21c-vagrant:    ACTION: Specify lesser values for memory parameters.

    oracle-21c-vagrant: Database Information:
    oracle-21c-vagrant: Global Database Name:ORCLCDB
    oracle-21c-vagrant: System Identifier(SID):ORCLCDB

...

real    20m26.471s
user    0m0.015s
sys     0m0.000s

空间占用14.8GB,还是挺多的。

我修改了一些默认设置,虚机内存改为4096,totalMemory改为3072。totalMemory的75%(2304M)被分配给SGA,25%(768M)被分配给PGA。

以下是一些初始化参数:

pga_aggregate_target                 big integer 768M
sga_max_size                         big integer 2304M
sga_min_size                         big integer 0
sga_target                           big integer 2304M

为方便,可修改SYS和SYSTEM口令:

cd ~oracle
./setPassword.sh Welcome1

其实空间将近15G并不是都用于数据库了,数据库安装加新数据库需要约12G:

[vagrant@oracle-21c-vagrant ~]$ df -h
