12c的增强ADR功能

12c中，增强的ADR功能，可以记录ddl操作的日志。

alter system set enable_ddl_logging=true;
create table test1(c number);
create table test2(c varchar2(10));
create user c##user1 identified by oracle;
drop user c##user1;
drop table test1;
drop table test2;


cd /u01/app/oracle/diag/rdbms/test/test/log/ddl


adrci
show log

测试如下：

启用ddl logging，并执行ddl操作

SYS@test>alter system set enable_ddl_logging=true;

System altered.


SYS@test>create table test1(c number);

Table created.

SYS@test>create table test2(c varchar2(10));

Table created.


SYS@test>create user c##user1 identified by oracle;

User created.

SYS@test>drop user c##user1;

User dropped.

SYS@test>drop table test1;

Table dropped.

SYS@test>drop table test2;

Table dropped.

SYS@test>

查看xml格式的操作记录
