ORA-06553: PLS-801: internal error [56319]，64位oracle降级为32位的处理

ORA-06553: PLS-801: internal error [56319]，64位oracle降级为32位的处理

将64位的的linux系统下的oracle备份集以及spfile以及controlfile的备份文件 恢复到32位的linux系统下,恢复的过程没有报错，但是在

登陆到oracle数据库时，在执行最简单的sql查询的时候报错，

ORA-06553: PLS-801: internal error [56319]，执行多个不同的sql反复报这个错误。

解决过程：

1、修改初始化文件,增加 _SYSTEM_TRIG_ENABLED = false参数

2、Stratup nomount

3、从源库备份一个控制文件，在目标库上重新创建控制文件。

4、Shutdown immediate

5、startup migrate

注：startup migrate表示降级，在9i，无论升级/降级 数据库都是startup migrate，10g后增加了upgrade参数，升级可直接用startup upgrade，降级仍是startup migrate.

6、@$ORACLE_HOME/rdbms/admin/utlirp.sql;

7、Shutdown immediate

8、Startup

9、@$ORACLE_HOME/rdbms/admin/utlrp.sql;

10、Shutdown immediate

11、再次修改初始化参数文件,删除参数 _SYSTEM_TRIG_ENABLED = false

12、Startup

转换完成(当时是照网上一个文档做的，现在仔细看来1、2、3、4、11这些步骤貌似都不需要的，最最主要的就是使用utlirp来把相关内容全部在32位平台下编译一遍)，顺便补充下utlirp的作用：

Rem NAME

Rem utlirp.sql - UTiLity script to Invalidate Pl/sql modules

Rem

Rem DESCRIPTION

Rem This script can be used to invalidate and all pl/sql modules

Rem (procedures, functions, packages, types, triggers, views)

Rem in a database.

Rem

Rem This script must be run when it is necessary to regenerate the

Rem compiled code because the PL/SQL code format is inconsistent with

Rem the Oracle executable (e.g., when migrating a 32 bit database to

Rem a 64 bit database or vice-versa).

Rem

Rem Please note that this script does not recompile invalid objects

Rem automatically. You must restart the database and explicitly invoke

Rem utlrp.sql to recompile invalid objects.

Rem

Rem USAGE

Rem To use this script, execute the following sequence of actions:

Rem 1. Shut down the database and restart in UPGRADE mode

Rem (using STARTUP UPGRADE or ALTER DATABASE OPEN UPGRADE)

Rem 2. Run this script

Rem 3. Shut down the database and restart in normal mode

Rem 4. Run utlrp.sql to recompile invalid objects. This script does

Rem not automatically recompile invalid objects.

Rem

Rem NOTES

Rem * This script must be run using SQL*PLUS.

Rem * You must be connected AS SYSDBA to run this script.

Rem * This script expects the following files to be available in the

Rem current directory:

Rem standard.sql

Rem dbmsstdx.sql

Rem * There should be no other DDL on the database while running the

Rem script. Not following this recommendation may lead to deadlocks.
