二、问题展示形式
ORA-600 [LibraryCacheNotEmptyOnClose] is reported in the alert.log on shutdown
The trace file shows the following call stack trace and will also include a System State:
kglshu kqlnfy kscnfy ksmshu opistp_real opistp opiodr ttcpip opitsk opiino opiodr opidrv sou2o opimai_real main libc_start_main

三、问题原因及其后果
This is a bug in that an ORA-600 error is reported when it is found during shutdown, after database close, that there are still objects in the library cache. It does not indicate any damage or a problem in the system.
Ignore the error as it just indicates that there are some items in the library cache when closing down the instance. The error itself occurs AFTER the database close and dismount stages so only affects the instance shutdown itself. Datafiles have been closed cleanly.

2、Metalink描述[ID 601316.1]
Changes
The problem surfaced after upgrading to 10.2.0.4.

Cause
The above warning messages has been introduced in 10.2.0.4 patchset. This warning message will be generated only if the log write time is more than 500 ms and it will be written to the lgwr trace file .

Solution
These messages are very much expected in 10.2.0.4 database in case the log write is more than 500 ms. This is a warning which means that the write process is not as fast as it intented to be .So probably you need to check if the disk is slow or not or for any potential OS causes. If everything looks fine at the hardware level or OS level then you can safely ignore these messages. The trace file can easily be deleted or truncated.

3、网上解决方案
the error may be suppressed by setting Event 10468 level 4.
alter system set events ‘10468 trace name context level 4’;
取消该trace命令为：
ALTER SYSTEM SET EVENTS ‘10468 trace name context off’;

mysql主从切换

1、修改配置文件
read-only=1（主库）
#read-only=1（备库）

2、查询从库状态
mysql> show processlist ;
+—-+————-+———–+——+———+——+—————————————————————————–+——————+
| Id | User | Host | db | Command | Time | State | Info |
+—-+————-+———–+——+———+——+—————————————————————————–+——————+
| 1 | root | localhost | ecp | Query | 0 | NULL | show processlist |
| 4 | system user | | NULL | Connect | 2 | Waiting for master to send event | NULL |
| 5 | system user | | NULL | Connect | 2 | Slave has read all relay log; waiting for the slave I/O thread to update it | NULL |
+—-+————-+———–+——+———+——+—————————————————————————–+——————+
3 rows in set (0.00 sec)

mysql> RESET SLAVE;
Query OK, 0 rows affected (0.03 sec)

7、主库变从库
mysql> RESET MASTER;
Query OK, 0 rows affected (0.06 sec)

mysql> RESET SLAVE;
Query OK, 0 rows affected (0.03 sec)

mysql> CHANGE MASTER TO
-> MASTER_HOST=’192.168.1.4′,

-> MASTER_LOG_FILE=’mysql-bin.000001′,
-> MASTER_LOG_POS=107;
Query OK, 0 rows affected (0.05 sec)

mysql> start slave;
Query OK, 0 rows affected (0.00 sec)

8、重启主和从库
[root@localhost mysql]# service mysql restart
Shutting down MySQL….[ OK ]
Starting MySQL…………….[ OK ]

9、检查主从是否都正常
主库
SHOW PROCESSLIST;
show master status \G

从库
SHOW PROCESSLIST;
start slave;
show slave status \G

如果有错误，根据错误提示，解决问题

最终生成需要处理的文件与处理

复制上面文件到目标端适当位置，然后可以修改并执行sql文件实现表传输表空间，或者使用impdp只是实现

相关说明
1、在使用rman之前，需要检查平台支持情况，如果不支持，需要先转换，然后使用catalog start with处理（10g），如果9i其他变通办法
2、在rman处理传输表空间的过程中，可以指定scn或者时间，既不完成恢复
UNTIL SCN 11379;或者UNTIL TIME ‘SYSDATE-1’;
3、rman的备份不能是resetlogs 打开数据库之前的
4、主要是利用10g的辅助实例自动实现处理，如果是9i，需要人工建立辅助实例
