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
