标题：impdp TRANSFORM参数

作者：惜分飞©版权所有[未经本人同意,不得以任何形式转载,否则有进一步追究法律责任的权利.]

在impdp的参数中有一个transform参数,用来实现在创建对象的时候对一些存储参数进行修改,官方关于这个参数说明:

TRANSFORM
要应用于适用对象的元数据转换。
有效的关键字为: OID, PCTSPACE, SEGMENT_ATTRIBUTES 和 STORAGE。

对主要的SEGMENT_ATTRIBUTES和STORAGE参数进行测试

SQL> create user xff identified by oracle default tablespace users;

用户已创建。

SQL> grant dba to xff;

授权成功。

SQL> create table xff.t_1 as select * from dba_objects;

表已创建。

SQL> exit

有朋友找我，由于客户硬件故障,导致控制文件损坏，重建控制文件的时候,由于失误依赖了100多个数据文件,并且进行了resetlogs操作,然后通过bbed修改文件头,再进行恢复,数据库在open过程中报ORA-03113错误

通过分析,确认是由于undo事务异常,通过一系列处理之后,数据库启动报

这个对象为核心对象obj$的index,无法直接rebuild,当然可以通过参考以前blog文档进行重建:bootstrap$核心index(I_OBJ1,I_USER1,I_FILE#_BLOCK#,I_IND1,I_TS#,I_CDEF1等)异常恢复—ORA-00701错误解决,直接对该坏块进行修复.

又一例数据库启动报ORA-600 kokasgi1错误的恢复请求

通过咨询是由于根据某厂商给出来的建议对对oracle的user$的系统默认用户update等操作

rename-sys



通过分析现在库的用户情况

20210729084444



通过一系列处理之后绕过kokasgi1错误,open数据库报ORA-12432错误

通过分析启动过程确认数据库在启动的时候访问lbacsys.lbac$pol表异常

*** 2021-07-28 18:31:15.593
USER (ospid: 3512): terminating the instance due to error 12432



经过修改文件让数据库不在访问该表,数据库启动正常
