DB2在线备份恢复

DB2在线备份恢复：

1.查看数据库：

[db2inst1@localhost ~]$ db2 list db directory

System Database Directory

Number of entries in the directory = 2

Database 1 entry:

Database alias = PAYMENT2

Database name = PAYMENT2

Local database directory = /home/db2inst1

Database release level = f.00

Alternate server port number =

2.删除数据库：（模拟灾难）

[db2inst1@localhost ~]$ db2 drop db payment2

DB20000I The DROP DATABASE command completed successfully.

[db2inst1@localhost ~]$ db2 list db directory

System Database Directory

Number of entries in the directory = 1

Alternate server hostname =

Alternate server port number =

3.找到备份的数据

[db2inst1@localhost ~]$ cd /home/db2inst1/payment2_bak

[db2inst1@localhost payment2_bak]$ ls

PAYMENT2.0.db2inst1.DBPART000.20130514083706.001 PAYMENT2.0.db2inst1.DBPART000.20130514090118.001

PAYMENT2.0.db2inst1.DBPART000.20130514085824.001

[db2inst1@localhost payment2_bak]$ ll

4.备份恢复命令

[db2inst1@localhost payment2_bak]$ db2 restore database payment2 from /home/db2inst1/payment2_bak taken at 20130514085824

DB20000I The RESTORE DATABASE command completed successfully.
5.查看数据库是否恢复：

[db2inst1@localhost payment2_bak]$ db2 list db directory

System Database Directory

Number of entries in the directory = 2

Database 1 entry:

Database alias = PAYMENT2

Database name = PAYMENT2

Local database directory = /home/db2inst1

Database release level = f.00

Comment =

Directory entry type = Indirect

Catalog database partition number = 0

Alternate server hostname =

Alternate server port number =

Database 2 entry:

Database alias = SAMPLE

Database name = SAMPLE

Local database directory = /home/db2inst1

Database release level = f.00

Comment =

Directory entry type = Indirect

Catalog database partition number = 0

Alternate server hostname =

Alternate server port number =

6.尝试连接数据库：

由于是在归档模式下，数据库恢复后，处于 ROLL-FORWARD PENDING 状态，所以不能连接

[db2inst1@localhost payment2_bak]$ db2 connect to payment2

SQL1117N A connection to or activation of database "PAYMENT2" cannot be made

because of ROLL-FORWARD PENDING. SQLSTATE=57019

7.前滚数据库，使之可用

[db2inst1@localhost ~]$ db2 "ROLLFORWARD DATABASE payment2 TO END OF LOGS AND COMPLETE OVERFLOW LOG PATH ("/home/db2inst1/payment2_archive_log/")"

Rollforward Status

Input database alias = payment2

Number of members have returned status = 1

Member ID = 0

Rollforward status = not pending

Next log file to be read =

Log files processed = S0000002.LOG - S0000003.LOG

Last committed transaction = 2013-05-14-01.01.28.000000 UTC

DB20000I The ROLLFORWARD command completed successfully.

[db2inst1@localhost ~]$ db2 connect to payment2

Database Connection Information

Database server = DB2/LINUX 10.1.2

SQL authorization ID = DB2INST1

Local database alias = PAYMENT2

[db2inst1@localhost ~]$ db2 list tables
