[英]Problem in connecting with oracle database
I have created one connection in Oracle with name Oracle18c .我在Oracle中创建了一个名为Oracle18c的连接。 Whenever I am trying to open Tables section then below pop-up is coming.
每当我试图打开表格部分时,就会出现下面的弹出窗口。 My Oracle server is running in Docker container.
我的Oracle 服务器在Docker容器中运行。 I tried to find the solution in the internet but I couldn't find it.
我试图在互联网上找到解决方案,但找不到。 I am new to the Oracle database.
我是Oracle数据库的新手。 Please help me.
请帮我。
By default, pluggable databases do not open automatically when their container database starts up.默认情况下,可插拔数据库不会在其容器数据库启动时自动打开。 A sysdba user needs to issue the command "alter pluggable database all open" to put them into read-write mode.
sysdba 用户需要发出命令“alter pluggable database all open”以使其进入读写模式。 Your error suggests that that hasn't happened here.
您的错误表明这里没有发生这种情况。 Check this link for details on how to do that: 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 .

If you're unable to login as sysdba from docker terminal.You can try with bash command如果您无法从 docker 终端以 sysdba 身份登录。您可以尝试使用 bash 命令
$ docker exec -it --user=oracle xedb bash
[oracle@13afebdbdbdc /]$
If that doesn't work as a Oracle user exclude --user
parameter,use bash command如果这不能作为 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 $ORACLE_SID
XE
If your environment returns nothing you can set environment with the command below如果您的环境没有返回任何内容,您可以使用以下命令设置环境
[oracle@13afebdbdbdc /]$ . oraenv -- dot space oraenv
ORACLE_SID = [XE] ?
The Oracle base remains unchanged with value /opt/oracle
[oracle@13afebdbdbdc /]$ rlwrap sqlplus / as sysdba
