oracle创建非容器数据库-526互联

1、 Oracle 19c rpm安装后配置的示例数据库是容器数据库，大部分系统中使用的还是以前的非容器数据库。在安装完rpm包后，可以使用dbca根据自己的需要创建数据库了，创建之前，先删除已经创建的示例数据库

./oracledb_ORCLCDB-19c delete

2、编辑一个dbca.rsp文件，用来生成数据库实例（文件目录在/home/oracle下）

responseFileVersion=/oracle/assistants/rspfmt_dbca_response_schema_v19.0.0

#-----------------------------------------------------------------------------
# Name : gdbName
# Datatype : String
# Description : Global database name of the database
# Valid values : <db_name>.<db_domain> - when database domain isn't NULL
# <db_name> - when database domain is NULL
# Default value : None
# Mandatory : Yes
#-----------------------------------------------------------------------------
gdbName=ORCLDB

templateName=/opt/oracle/product/19c/dbhome_1/assistants/dbca/templates/General_Purpose.dbc

sysPassword=system123

systemPassword=system123

datafileDestination=

characterSet=UTF8

3、使用dbca创建数据库

dbca -silent -createDatabase -responseFile /home/oracle/dbca.rsp

4、修改oracle环境变量

export ORACLE_PFILE=/opt/oracle/product/19c/dbhome_1/dbs/initORCLDB.ora

export ORACLE_SID=ORCLDB

5、执行source .bash_profile

6、编辑一个initORCL.ora的配置文件(可以从别的地方复制一个，也可以按这个写一个initORCL.ora的文件)

7、修改监听配置文件

把这个目录下的监听文件移动到上一级admin目录下

然后编辑监听文件(在文本最下方添加)

LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.3.51)(PORT = 1521))
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
)
)

SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(GLOBAL_NAME = ORCLDB)
(SID_NAME = ORCLDB)
(ORACLE_HOME = /opt/oracle/product/19c/dbhome_1)
)
)
