附錄 docker容器自啓：
docker已啓動的情況下：docker update --restart=always oracle
第一步 拉取和下載docker鏡像
[root@localhost ~]# docker pull registry.cn-hangzhou.aliyuncs.com/helowin/oracle_11g
Using default tag: latest
latest: Pulling from helowin/oracle_11g
ed5542b8e0e1: Pull complete
a3ed95caeb02: Pull complete
1e8f80d0799e: Pull complete
Digest: sha256:4c12b98372dfcbaafcd9564a37c8d91456090a5c6fb07a4ec18270c9d9ef9726
Status: Downloaded newer image for registry.cn-hangzhou.aliyuncs.com/helowin/oracle_11g:latest
第二步 查看docker中的鏡像文件
[root@localhost ~]# docker images
REPOSITORY TAG IMAGE ID CREATED SIZEregistry.cn-hangzhou.aliyuncs.com/helowin/oracle_11g latest 3fa112fd3642 3 years ago 6.85GB
然後運行鏡像
docker run -d -p 1521:1521 --name oracle registry.cn-hangzhou.aliyuncs.com/helowin/oracle_11g
第三步 檢查容器是否運行成功
[root@localhost ~]# docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
a151f9478f94 registry.aliyuncs.com/helowin/oracle_11g "/bin/sh -c '/home/o…" About a minute ago Up 30 seconds 0.0.0.0:1521->1521/tcp oracle
啓動oracle
[root@localhost ~]# docker start oracle
第四步 進入並設置oracle
4.1 [root@localhost ~]# docker exec -it oracle bash
4.2
[oracle@a151f9478f94 /]$ exit
exit
[root@localhost ~]#
4.3切換回root用戶
編輯環境變量 vi /etc/profile 在文件的末尾添加一下內容
export ORACLE_HOME=/home/oracle/app/oracle/product/11.2.0/dbhome_2
export ORACLE_SID=helowin
export PATH=$ORACLE_HOME/bin:$PATH
4.4 使這個配置修改生效
[root@localhost ~]# source /etc/profile
4.5進入容器（此處的id就是第一個命令下的id），加載一下用戶環境變量，進入容器後，自動是oracle用戶
[root@localhost ~]# docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
a151f9478f94 registry.aliyuncs.com/helowin/oracle_11g "/bin/sh -c '/home/o…" 3 hours ago Up 3 hours 0.0.0.0:1521->1521/tcp oracle
[root@localhost ~]# docker exec -it a151f9478f94 /bin/bash
[oracle@a151f9478f94 /]$ source ~/.bash_profile
[oracle@a151f9478f94 /]$ sqlplus /nolog

With the Partitioning, OLAP, Data Mining and Real Application Testing options
[oracle@a151f9478f94 /]$ exit ##回到root用戶
exit
[root@localhost ~]#
上面的步驟都完成後，嘗試用plSql連接
ORACLE_DOCKER =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.103)(PORT = 1521))
)
(CONNECT_DATA =
(SERVICE_NAME = helowin)
)
)
連接完成後，會報錯，client編碼和數據庫編碼格式不一致？
把oracle數據編碼格式
1.cmd
2.輸入set ORACLE_SID=你想進入的數據庫的那個sid
3.輸入 sqlplus /nolog
4.將數據庫啓動到RESTRICTED模式下做字符集更改：
SQL> conn /as sysdba
Connected.
SQL> shutdown immediate;
Database closed.
Database dismounted.
ORACLE instance shut down.
SQL> startup mount
ORACLE instance started.
Total System Global Area 236000356 bytes

Database mounted.
SQL> ALTER SYSTEM ENABLE RESTRICTED SESSION;
System altered.
SQL> ALTER SYSTEM SET JOB_QUEUE_PROCESSES=0;
System altered.
SQL> ALTER SYSTEM SET AQ_TM_PROCESSES=0;
System altered.
SQL> alter database open;
Database altered.
SQL> ALTER DATABASE CHARACTER SET ZHS16GBK;
ALTER DATABASE CHARACTER SET ZHS16GBK
*
ERROR at line 1:
ORA-12712: new character set must be a superset of old character set
提示我們的字符集：新字符集必須爲舊字符集的超集，這時我們可以跳過超集的檢查做更改：
SQL> ALTER DATABASE character set INTERNAL_USE ZHS16GBK;
Database altered.
SQL> select * from v$nls_parameters;
略
19 rows selected.
重啓檢查是否更改完成：
SQL> shutdown immediate;
Database closed.
Database dismounted.
ORACLE instance shut down.
SQL> startup
ORACLE instance started.
Total System Global Area 236000356 bytes
Fixed Size 451684 bytes

SQL> select * from v$nls_parameters;
