命令行删除Workspace

官方参考文档

实验的时候创建很多Workspace,所以想要一次性全部删除,具体的删除操作可以参考文档:

http://docs.oracle.com/cd/E17556_01/doc/admin.40/e15521/adm_mg_wrkspc.htm#CHDHBEFI

删除的具体操作步骤与说明

To delete a workspace in a runtime development environment:

Start SQL*Plus and connect to the database where Oracle Application Express is installed as SYS. For example:

On Windows:
<strong>SYSTEM_DRIVE:\ sqlplus /nolog
connect sys as sysdba</strong>
On UNIX and Linux:
<strong>$ sqlplus /nolog
connect sys as sysdba</strong>
When prompted enter the appropriate password.

Run the following statement:

<strong>ALTER SESSION SET CURRENT_SCHEMA = APEX_040000
</strong>Run the following statement:

<strong>BEGIN
APEX_INSTANCE_ADMIN.REMOVE_WORKSPACE(WORKSPACE_NAME, DROP_USER, DROP_TABLESPACE)
END;</strong>
Where:

WORKSPACE_NAME is the name of the workspace.
DROP_USER is either Y or N. The default is N.
DROP_TABLESPACE is either Y or N. The default is N.
在决定CURRENT_SCHEMA的时候,可以先查看本地安装的数据库内容和具体的APEX版本。

查看APEX版本

SQL> select version_no from apex_release;
VERSION_NO
--------------------------------------------------------------------------------
4.0.2.00.09

查看数据库中的schema情况

SQL> select username from all_users;

USERNAME
------------------------------------------------------------
XS$NULL
APEX_040000
APEX_PUBLIC_USER
FLOWS_FILES
MDSYS
ANONYMOUS
XDB
CTXSYS
OUTLN
SYSTEM
SYS

已选择11行。

GUI删除Workspace

访问GUI管理界面

通过http://127.0.0.1:8080/apex/apex_admin可以进入APEX后台管理GUI。用户名为Admin,初始密码记不清了,按照官方文档的指导,可以轻松重置密码。

重置GUI管理密码

通过官方指南http://docs.oracle.com/cd/E23903_01/doc/doc.41/e21673/otn_install.htm#BABDEAFD,可以很容易地重置密码。首先需要进入脚本所在目录。

C:\oraclexe\app\oracle\product\11.2.0\server\apex>dir
 驱动器 C 中的卷没有标签。
 卷的序列号是 3CCF-056C

 C:\oraclexe\app\oracle\product\11.2.0\server\apex 的目录

2014-01-14  22:05    <DIR>          .
2014-01-14  22:05    <DIR>          ..
2011-08-27  10:00             1,687 <strong>apxchpwd.sql</strong>
2011-08-27  10:00             3,005 apxconf.sql
2011-08-27  10:00             4,537 apxremov.sql
2011-08-27  10:00             1,625 apxxepwd.sql
2011-08-27  10:00            10,626 gen_inst.sql
               5 个文件         21,480 字节
               2 个目录 19,138,473,984 可用字节
然后运行上面粗体文件即可,命令如下:
SYSTEM_DRIVE:\ sqlplus /nolog
SQL> CONNECT SYS as SYSDBA
Enter password: SYS_password

@apxchpwd

创建Workspace

GUI创建Workspace

GUI创建Workspace有两种途径,一种是面向开发人员的http://hostname:port/apex,还有一种就是面向APEX管理员的http://127.0.0.1:8080/apex/apex_admin。

异常处理

如果在创建的过程中出现了下面的错误,那可能是之前删除Workspace时没有清除所有相关数据,所以我们需要继续手工删除这些数据。

ORA-00001: unique constraint (APEX_040000.WWV_FLOW_PROV_COMPANY_NAME) violated

用下面命令删除相关数据后,就可以解决上面的约束冲突问题(冲突是由表中的一个索引引起的)。
SQL> DELETE FROM apex_040000.WWV_FLOW_PROVISION_COMPANY;
