我尝试使用MongoDB Shell连接到Oracle Database 23c Free – Developer Release
首先
我在安装了Oracle Database 23c Free – Developer Release的环境中，引入了MongoDB的客户端Oracle Database API for MongoDB来构建JSON-Relational Duality验证环境，并通过MongoDB Shell访问Oracle Database 23c。
0.安装免费的Oracle数据库23c开发者版本
根据这篇文章的指示，在Oracle Linux 8上安装Oracle Database 23c Free – Developer Release。
1. 安装 Java（JDK）
我将安装JDK。
[opc@23c ~]$ sudo dnf install -y java

[opc@23c ~]$
2. 安装MongoDB Shell
我要添加MongoDB仓库。
[opc@23c ~]$ sudo vi /etc/yum.repos.d/mongodb-org-6.0.repo
[mongodb-org-6.0]
name=MongoDB Repository
baseurl=https://repo.mongodb.org/yum/redhat/$releasever/mongodb-org/6.0/x86_64/
gpgcheck=1
enabled=1
gpgkey=https://www.mongodb.org/static/pgp/server-6.0.asc
安装MongoDB Shell。
[opc@23c ~]$ sudo dnf install -y mongodb-mongosh

3. 安装ORDS
我要切换到Oracle用户。
[opc@23c ~]$ sudo su - oracle
Last login: Mon May 15 12:32:08 GMT 2023 on pts/0
[oracle@23c ~]$
创建一个用于创建ORDS的目录。
[oracle@23c ~]$ mkdir /opt/oracle/ords
[oracle@23c ~]$
我会切换到创建的目录下。
[oracle@23c ~]$ cd /opt/oracle/ords
[oracle@23c ords]$
使用中文下载ORDS安装程序。

我将使用MongoDB Shell连接到Oracle Database 23c的mongo_test用户。
由于ORDS使用自签名证书，我将使用–tlsAllowInvalidCertificates选项。
[oracle@23c ~]$ mongosh --tlsAllowInvalidCertificates 'mongodb://mongo_test:MyPassword1!@localhost:27017/mongo_test?authMechanism=PLAIN&authSource=$external&ssl=true&retryWrites=false&loadBalanced=true'

Using MongoDB: 4.2.14
Using Mongosh: 1.8.2
For mongosh info see: https://docs.mongodb.com/mongodb-shell/
To help improve our products, anonymous usage data is collected and sent to MongoDB periodically (https://www.mongodb.com/legal/privacy-policy).
You can opt-out by running the disableTelemetry() command.
mongo_test> db.collections.find();
mongo_test>
我能够从MongoDB Shell成功连接到Oracle Database 23c。
