Question

我在 Oracle 中创建了一个名称为 Oracle18c 的连接。每当我尝试打开表格部分时，就会弹出以下窗口。我的 Oracle服务器在 Docker 容器中运行。我试图在Internet上找到解决方案，但找不到。我是 Oracle 数据库的新手。请帮助我。

Answer 1

默认情况下，可插拔数据库在其容器数据库启动时不会自动打开。 sysdba用户需要发出命令“ alter pluggable database all open”以将它们置于读写模式。您的错误表明这里没有发生。检查此链接以获取有关执行此操作的详细信息： https://oracle-base.com/articles/12c/multitenant-startup-and-shutdown-cdb-and-pdb-12cr1#:~:text=Pluggable%20Database%20(PDB)%20Automatic%20Startup,-The%2012.1.&text=Prior%20to%2012.1.,or%20all%20of%20the%20PDBs。

我的容器是从头开始构建的Oracle 18 xe源：github。

$ docker ps

实例已启动并正在运行，并且可插入数据库

如果无法从docker终端以sysdba身份登录。可以尝试使用bash命令

$ docker exec -it --user=oracle xedb  bash
[oracle@13afebdbdbdc /]$

如果不能作为Oracle用户排除--user参数，请使用bash命令

$ docker exec -it xedb  bash
bash-4.2# su oracle   -- switch oracle user 
[oracle@13afebdbdbdc /]$ echo $ORACLE_HOME   -- verify environment
/opt/oracle/product/18c/dbhomeXE
[oracle@13afebdbdbdc /]$ echo $ORACLE_SID
 XE

如果您的环境未返回任何内容，则可以使用以下命令设置环境

    [oracle@13afebdbdbdc /]$ . oraenv   -- dot space oraenv
    ORACLE_SID = [XE] ?
    The Oracle base remains unchanged with value /opt/oracle
    [oracle@13afebdbdbdc /]$ rlwrap sqlplus / as sysdba
