db2 开启归档日志的功能

Posted on 2010-03-20 00:55 Prayer 阅读(5407) 评论(2)  编辑 收藏 引用 所属分类: DB2
1、 查看默认情况下的设置:
   db2 get db cfg for db_name |grep -i log
   结果如下:
Log retain for recovery enabled             (LOGRETAIN) = OFF
 User exit for logging enabled                (USEREXIT) = OFF
 HADR log write synchronization mode     (HADR_SYNCMODE) = NEARSYNC
 First log archive method                 (LOGARCHMETH1) = OFF
 默认情况为循环日志
 
2、更改为归档日志:
   db2 update db cfg for db_name using LOGRETAIN ON
  
   运行后结果如下:
Log retain for recovery enabled             (LOGRETAIN) = RECOVERY
 User exit for logging enabled                (USEREXIT) = OFF
 HADR log write synchronization mode     (HADR_SYNCMODE) = NEARSYNC
 First log archive method                 (LOGARCHMETH1) = LOGRETAIN、
 
  更改归档目录:
  db2 update db cfg for db_name using LOGARCHMETH1 "disk:/archive/db_name_db_log"
 
 运行后结果如下:
 Log retain for recovery enabled             (LOGRETAIN) = RECOVERY
 User exit for logging enabled                (USEREXIT) = OFF
 HADR log write synchronization mode     (HADR_SYNCMODE) = NEARSYNC
 First log archive method                 (LOGARCHMETH1) =  
                                                    DISK:/archivelog/db_name_db_log/
 
3、手工归档方法:
  db2 archive log for db db_name
  (但前提是没数据库连接,很奇怪,不知道为什么)
 如下:
[db2inst1@home SQLOGDIR]$ db2 connect to fangys
   Database Connection Information
 Database server        = DB2/LINUX 8.2.9
 SQL authorization ID   = DB2INST1
 Local database alias   = FANGYS
[db2inst1@home SQLOGDIR]$ db2 archive log for db fangys
SQL1493N  The application is already connected to an active database.
  -------不知道为什么不行!!!!
 
[db2inst1@home SQLOGDIR]$ db2 connect reset
DB20000I  The SQL command completed successfully.
[db2inst1@home SQLOGDIR]$ db2_ps

application 已经连接了(其他的)活动数据库,当然要断开当前的连接。
