Docker 上的 Oracle 数据库非常非常慢

Question

我根据以下网站中的说明和 dockerfile 在 Docker 上创建了一个 Oracle 数据库。

https://github.com/oracle/docker-images/tree/master/OracleDatabase

创建图像并运行后

docker run --name oracle -p 1521:1521 -p 5500:5500 -e ORACLE_SID=ORCLCDB -e ORACLE_PDB=ORCLPDB1 oracle/database:12.1.0.2-ee

启动一个 oracle 容器。但速度非常慢。

以下是日志：

...

任何人都可以告诉我如何加快速度。花了20分钟才完成。我在该日志的末尾看到一条消息，不确定它是否与缓慢有关。

默认 pga_aggregate_limit 值对于系统中的物理内存量来说太高 pga_aggregate_limit 是 2048 MB 基于物理内存的限制，SGA 使用量是 2020 MB

Answer 1

我设法显着降低了数据库启动时间。这个想法是拍摄已配置和正在运行的数据库的快照。更多信息和分步指南可以在这里找到：https://medium.com/@ggajos/drop-db-startup-time-from-45-to-3-minutes-in-dockerized-oracle-19-3 -0-552068593deb

Answer 2

https://github.com/oracle/docker-images/issues/141 由于安装步骤而导致速度缓慢。感谢贾斯汀·凯夫的及时帮助。
