db2 "rollforward db jyc to end of logs and complete overflow log path (x:\db2\log)"

报错：

归档日志路径

关于错误：SQL1265N的错误处理

步骤一、恢复数据库

db2inst1@db2server:~> db2 "restore db patchdb logs taken at 20140124061304

LOGTARGET /home/db2inst1/dblog/"

DB20000I The RESTORE DATABASE command completed successfully.

步骤二、前滚数据库

db2inst1@db2server:~/dblog> db2 "ROLLFORWARD DATABASE patchdb TO END OF LOGS AND COMPLETE

OVERFLOW LOG PATH ('/home/db2inst1/dblog/')"

SQL1265N The archive log file "S0000017.LOG" is not associated with the

current log sequence for database "PATCHDB" on node "0".

步骤三、拷贝需要前滚的最小日志文件

db2inst1@db2server:~> cd /home/db2inst1/dblog/

db2inst1@db2server:~/dblog> ls -rtl

total 16

drwxr-x--- 4 db2inst1 db2iadm1 4096 Jan 24 06:21 db2inst1

-rw------- 1 db2inst1 db2iadm1 12288 Jan 24 06:35 S0000017.LOG

db2inst1@db2server:~/dblog> cp S0000017.LOG /home/db2inst1/db2inst1/NODE0000/SQL00003/SQLOGDIR/

db2inst1@db2server:~/dblog> db2 "ROLLFORWARD DATABASE patchdb TO END OF LOGS AND COMPLETE "

SQL1271W Database "PATCHDB" is recovered but one or more table spaces are

off-line on node(s) "0".

步骤四、查询前滚状态

db2inst1@db2server:~/dblog> db2 "rollforward db patchdb query status"

Rollforward Status

Input database alias = patchdb

Number of nodes have returned status = 1

Node number = 0

Rollforward status = not pending

Next log file to be read =

Log files processed = S0000017.LOG - S0000017.LOG

Last committed transaction = 2014-01-24-11.13.22.000000 UTC
