Oracle数据库安装在docker容器中

1首先查看容器

docker ps

　　技术分享图片

2进入oracle容器

docker exec -it 7f0f3f2d4f88 /bin/bash

3导出整个库：这个有问题，会吧helowin实例下的所有数据都导出:

DATA_PUMP_DIR为oracle中默认备份文件件

expdp SDWEB/SDWEB@helowin dumpfile=aircms.dmp logfile=airscm.log 
full=y  directory=DATA_PUMP_DIR

如果报错，错误如下

Connected to: Oracle Database 11g Enterprise Edition Release 11.1.0.7.0 - 64bit Production
With the Partitioning, Real Application Clusters, OLAP, Data Mining
and Real Application Testing options

ORA-39002: invalid operation
ORA-39070: Unable to open the log file.
ORA-29283: invalid file operation
ORA-06512: at "SYS.UTL_FILE", line 536
ORA-29283: invalid file operation

解决方法：查文档发现，缺省Directory为DATA_PUMP_DIR

查看DATA_PUMP_DIR的值，

A)进入到sqlplus中查看它的值

sqlplus /nolog

b)切换系统用户

 conn sys/ as sysdba;

c)查看默认值

 select * from dba_directories where directory_name=‘DATA_PUMP_DIR‘;

得出的值：/home/oracle/app/oracle/admin/orcl/dpdump/

但实际上路径中只有：/home/oracle/app/oracle/admin/helowin/dpdump/

需要创建/home/oracle/app/oracle/admin/orcl/dpdump/目录

4继续导出数据库

expdp SDWEB/SDWEB@helowin dumpfile=aircms.dmp logfile=airscm.log full=y  directory=DATA_PUMP_DIR

5导出成功

/home/oracle/app/oracle/admin/orcl/dpdump/aircms.dmp

6拷贝到系统路径下

7f0f3f2d4f88:为容器id

docker cp 7f0f3f2d4f88:/home/oracle/app/oracle/admin/orcl/dpdump/aircms.dmp /home/dev/
