PL/Vision安装和使用

Quest公司提供的免费PLSQL代码库，提供了不少增强型功能，如果是做Oracle数据库开发的人，可以拿来学习或者直接使用。

一、说明

The PL/Vision Code Library provides over 1,000 PL/SQL functions and procedures that extend the capabilities of the PL/SQL language.
PL/Vision Code Library is a freeware product. Quest Support does not support this product. If you have any questions about PL/Vision, please send an email to [e-mail].
PL/Vision Code Library Functional Categories:
    * String Operations
    * Date Management
    * Error Management
    * Dynamic SQL Operations
    * Transaction Management
    * Developer Utilities
    * Data Dictionary Access
The PL/Vision Code Library requires PL/SQL Release 2.3.4 and above (corresponding to Oracle Server Release 7.3.4 and above). All packages have been tested through Oracle Version 9.2.

二、下载和安装软件包

软件包下载： http://www.toadworld.com/LinkClick.aspx?fileticket=YJTcriH32PQ=&tabid=316
unzip the KXPLVISION_v1.0.zip file into your directory of choice.
Run the KXPLVISION_v1.0.exe to install the Code Library.
To view the Code Library, from your Start Menu, select Programs > Quest Software > PL/Vision Code Library > PL/Vision Code Library.

三、安装PL/Vision到数据库

1、安装过程就是新建一些表和package对象到指定的数据库用户下。
unix服务器上安装注意：
把 C:\Program Files\Quest Software\PLVision Code Library 下各目录的文件以Ascii方式上传至unix服务器后，一些unix主机会把传输的文件名转成大写，这样就需要执行 $ sh ./plvlcase.sh < filelist 把文件名转成小写。

2、新建一个用户（最好取名为plvision）并且赋权，当然也可以使用一个已经存在的数据库用户。

SQL> conn /as sysdba
SQL> drop user plvision cascade;
SQL> create user plvision identified by oss;
SQL> grant dba to plvision;
SQL> grant select on DBA_COL_COMMENTS to plvision;
grant select on DBA_CONS_COLUMNS to plvision;
grant select on DBA_CONSTRAINTS to plvision;
grant select on DBA_DEPENDENCIES to plvision;
grant select on DBA_IND_COLUMNS to plvision;
grant select on DBA_JOBS_RUNNING to plvision;
grant select on DBA_TAB_COLUMNS to plvision;
grant select on DBA_ERRORS to plvision;
grant select on DBA_INDEXES to plvision;
grant select on DBA_JOBS to plvision;
grant select on DBA_OBJECTS to plvision;
grant select on DBA_SEQUENCES to plvision;
grant select on DBA_SOURCE to plvision;
grant select on DBA_SYNONYMS to plvision;
grant select on DBA_TABLES to plvision;
grant select on DBA_TRIGGERS to plvision;
grant select on DBA_VIEWS to plvision;
grant execute on DBMS_PIPE to plvision;
grant create PROCEDURE, create PUBLIC SYNONYM, drop PUBLIC SYNONYM, 
create SEQUENCE, create TABLE, create VIEW to plvision;
grant unlimited tablespace to plvision;

 

 

 

3、以新用户登陆并安装

C:\Documents and Settings\sz>cd C:\Program Files\Quest Software\PLVision Code Library\Source
C:\Program Files\Quest Software\PLVision Code Library\Source>sqlplus plvision/oss@orcl42
SQL> @plvinstall

 
按照提示一步步确认：
...
Install (I) or Quit (Q): I
...
Press <ENTER> to install for Oracle 9.2, or choose from the list: 5
...
Enter component(s) you want to install (1/2/3/P) : 3
...
*** Press ENTER to acknowledge and continue...
...
... Press <ENTER> to continue ...
...
... Press <ENTER> to continue ...
...
Installation process complete. Press ENTER to close SQL*Plus...

 

4、安装后工作
1） 为了操作OS文件和调度jobs，需要确认Oracle本身已经安装了 UTL_FILE 和 DBMS_JOB 两个包。
并设置以下初始化参数：
utl_file_dir = <directory>
job_queue_processes=<number, 0-36, recommended 3>
job_queue_interval=<seconds, 1-3600, recommended 60>
job_queue_keep_connections = <TRUE or FALSE>

C:\Program Files\Quest Software\PLVision Code Library\Source>sqlplus sys/change_on_install@orcl42 as sysdba
SQL> set lines 256
SQL> alter system set utl_file_dir='/opt/oracle' scope=spfile;
SQL> alter system set job_queue_processes=3 scope=spfile;
SQL> shutdown immediate
SQL> startup
SQL> show parameter utl_file_dir
SQL> show parameter job

 

 

2）为了使用PLVdyn包（PLVdyn offers an easy-to-use interface to the built-in DBMS_SQL package）

SQL> conn plvision/oss@orcl42
SQL> grant execute on plvdyn to public;

 

 

3）检查是否有失效对象

四、分析PL/Vision

SQL> conn plvision/oss@orcl42
SQL> @plvanalyze

 

 

 

五、删除PL/Vision

SQL> conn plvision/oss@orcl42
SQL> @plvremove
...
Enter option : 4
...
... Press <ENTER> to continue ...

 

 

 

六、使用PL/Vision

SQL> conn wacos/oss@orcl42
SQL> exec PLVddd.tbl(user,'tab_test2');
/*============PL/Vision Reverse Engineering ==============
| Auto-Generated DDL (3？ 13, 2008 17:01:38)
| --------------------------------------------------------
| Table Generated For wacos.tab_test2
|========================================================*/
CREATE TABLE wacos.tab_test2
(
col2 VARCHAR2(10),
col5 CHAR(1)
     CHECK (col5 in ('1','2','3')),
testlob BLOB
)
;
ALTER TABLE wacos.tab_test2
   ADD (
         PRIMARY KEY (COL2,COL5)
   );
PL/SQL 过程已成功完成。
