如果使用的是 Express 版本的, 那就没有问题。
因为 作了很多的限制。
比如说在10g中用户数据最大为4G, 11G中最大为11G,如果超出大小就会报ora-12952/ora-12953的错误,毕竟免费的,不能让你肆无忌弹地用。
官方文档如是说:
10G xe版本的限制:
1. Express Edition is limited to a single instance on any server;
2. Express Edition may be installed on a multiple CPU server, but may only be executed on one processor in any server;
3. Express Edition may only be used to support up to 4GB of user data (not including Express Edition system data);
4. Express Edition may use up to 1 GB RAM of available memory.
