启动数据库报错，ORA-18008: cannot find OUTLN schema问题现象：
数据库版本 Oracle 11g r2

会话 ID: 683 序列号: 3
hrdb1>!oerr ora 18008
18008, 00000, "cannot find OUTLN schema"
// *Cause: The database creation script that creates this schema must not
// have been executed.
// *Action: Review the log files to see what happened when the database
// was created.
问题原因：
outlin用户被误删除
解决方法：
按照metalink上的解决办法，先修改replication_dependency_tracking参数，重建数据库outln用户及相关对象即可。
1，启动到mount状态，修改replication_dependency_tracking参数
alter system set replication_dependency_tracking =false scope=spfile;
2，启动数据库至open状态
hrdb1>shutdown immediate
hrdb1>startup
3，执行脚本doptim.bsq，Oracle 10g版本可参考执行附录脚本
@$Oracle_HOME/rdbms/admin/doptim.bsq
此时，用户已创建
hrdb1>select username from dba_users;
USERNAME
------------------------------
OUTLN
4，修改回replication_dependency_tracking参数为true
alter system set replication_dependency_tracking =true scope=spfile;
5，重新启动数据库，系统恢复正常
hrdb1>shutdown abort
Oracle 例程已经关闭。
hrdb1>startup
Oracle 例程已经启动。

数据库装载完毕。
数据库已经打开。
hrdb1>select username from dba_users;
USERNAME
------------------------------
WJ
OUTLN
SYS
SYSTEM
HR
STRMADMIN
已选择6行。
由于版本是Oracle 11g，直接执行相关脚本即可，oracle 10g版本可以参考《Script to Create User OUTLN in 10.2 [ID 422983.1]》
备注：用于复制的一个参数，第一次碰到，做个记录
REPLICATION_DEPENDENCY_TRACKING enables or disables dependency tracking for read/write operations to the database. Dependency tracking is essential for propagating changes in a replicated environment in parallel.

不行，网上看看能不能恢复数据，无解决方案！！
幸好这时一个mysql从服务器（我做了一个主从mysql热备份）！！！没办法，数据恢复不了就重新在复制一份吧！
上述步骤后还是不能启动数据
试试重新初始化：

FATAL ERROR: Could not find ./bin/my_print_defaults
If you compiled from source, you need to run 'make install' to
copy the software into the correct location ready for operation.
If you are using a binary release, you must either be at the top
level of the extracted archive, or pass the --basedir option
pointing to that location.
