重编译Oracle中的invalid对象

(环境Oracle 9i，所有语句在sqlplus下执行)

1、invalid对象的查询

查询invalid对象的总个数

select count(*) from dba_objects where status='INVALID';

分类查询invalid对象的个数

select owner,object_type,count(*) from dba_objects where status='INVALID' group by owner,object_type;

查询对象的详细信息

select owner, object_name,object_type from dba_objects where status =’INVALID’;

2、手动重新编译

重编译语句的格式：

Alter procedure <owner>.<procedure_name> compile;
Alter function <owner>.<function_name> compile;
Alter view <owner>.<view_name> compile;
Alter package <owner>.<package_name> compile;
Alter package <owner>.<package_name> compile body;
Alter materialized view <owner>.<Package_name> Compile;

使用脚本编译

视图、包等主要对象：

Spool recompile.sql
select 'alter '||object_type|| ' ' || owner ||'.'||object_name || ' compile;' from dba_objects where status='INVALID';
Spool off
@recompile.sql

包体

Spool pkg_body.sql
Select 'alter package '||object_type|| ' ' || owner ||'.'||object_name || ' compile body;' From dba_objects where status <> 'VALID' And object_type = 'PACKAGE BODY';
Spool off
@pkg_body.sql

未定义对象（未测试）

Spool undefined.sql
select alter materizlized view ' || owner ||'.'||object_name || ' compile;' From dba_objects where status <> 'VALID' And object_type =‘UNDEFINED’;
Spool off
@undefined.sql

java类(未测试)

Spool javaclass.sql
Select 'alter java class ' || owner ||'.'||object_name || ' resolve;' from dba_objects where status <> 'VALID' And object_type ='JAVA CLASS';
Spool off
@javaclass.sql

typebody

Spool typebody.sql
Select 'alter type ' || owner ||'.'||object_name || ' compile body;' From dba_objects where status <> 'VALID' And object_type ='TYPE BODY';
Spool off
@typebody.sql

public_synonym（未测试）

Spool public_synonym.sql
Select 'alter public synonym ' || owner ||'.'||object_name || ' compile;' From dba_objects Where status <> 'VALID' And owner = 'PUBLIC' And object_type = 'SYNONYM';
Spool off
@public_synonym.sql

3、若编译出错

若重编译时，出现编译错误时，使用"show error"查看错误，针对错误再进行处理

在SDE中，也可以尝试先移动包，再重新生成：
SQL> DROP PACKAGE BODY sde.sde_util;
SQL> DROP PACKAGE sde.sde_util;
SQL> commit;
SQL> exit;
Navigate to the $SDEHOME/lib directory, log into SQL*Plus as the SDE user then execute the following commands :
SQL> start SDE_UTIL.sps;
SQL> start SDE_UTIL.spb;
SQL> commit;

4、其它解决方法

使用dbms_dll.alter_compile

exec dbms_ddl.alter_compile ('PROCEDURE','SCOTT','TEST');

使用DBMS_UTILITY.COMPILE_SCHEMA

exec dbms_utility.compile_schema('SCOTT');

使用UTLRP.SQL

@utlrp.sql
