???? db2 日志模式分為循環(huán)歸檔，和日志歸檔模式，兩種日志的原理介紹的很多了，我主要記錄一下我實際操作的步驟

???? 版本： v9.7 （建立了4個分區(qū)）

???? OS： AIX5.3

???? DB2 默認(rèn)為循環(huán)歸檔，根據(jù)應(yīng)用要求調(diào)整為日志歸檔模式

??? db2 connect to cqtest1

??? db2 force application all

???? [ibm_test1]/db2log>db2 "UPDATE DB CFG FOR CQTEST1? USING LOGARCHMETH1? 'Disk:/db2log/db2logar'"
DB20000I? The UPDATE DATABASE CONFIGURATION command completed successfully.

???? [ibm_test1]/db2log>db2 connect to cqtest1?? （需要備份數(shù)據(jù)庫）
SQL1116N? A connection to or activation of database "CQTEST1" cannot be made
because of BACKUP PENDING.? SQLSTATE=57019

??[ibm_test1]/db2log>db2 backup database cqtest1 to /db2log/backup?? （24G數(shù)據(jù)備份了5分鐘）

Backup successful. The timestamp for this backup image is : 20120222172556

[ibm_test1]/db2log>db2 connect to cqtest1? (連接成功）

?? Database Connection Information

?Database server??????? = DB2/AIX64 9.7.3
?SQL authorization ID?? = DB2INST1
?Local database alias?? = CQTEST1

?

但是當(dāng)我連接上數(shù)據(jù)庫建表是還是報錯 SQL1116N? A connection to or activation of database "CQTEST1" cannot be made
because of BACKUP PENDING.? SQLSTATE=57019

?

什么原因呢？原來在分區(qū)數(shù)據(jù)庫上執(zhí)行 backup database 只能備份一個node。

換成

db2_all "db2 backup db cqtest1 to /db2log/backup/dpf_1,/db2log/backup/dpf_2,/db2log/backup/dpf_3,/db2log/backup/dpf_4"

[ibm_test1]/db2log/backup>db2_all "db2 backup db cqtest1 to /db2log/backup/dpf_1,/db2log/backup/dpf_2,/db2log/backup/dpf_3,/db2log/backup/dpf_4"
?

Backup successful. The timestamp for this backup image is : 20120222180237

ibm_test1: db2 backup db cqtest1 ... completed ok
?

Backup successful. The timestamp for this backup image is : 20120222180719

ibm_test1: db2 backup db cqtest1 ... completed ok
?

Backup successful. The timestamp for this backup image is : 20120222181204

ibm_test1: db2 backup db cqtest1 ... completed ok
?

Backup successful. The timestamp for this backup image is : 20120222181650

ibm_test1: db2 backup db cqtest1 ... completed ok

?

后在重啟數(shù)據(jù)庫問題就解決了。

?

?總結(jié)一下

db2 connect to cqtest1

db2 force application all

db2 "UPDATE DB CFG FOR CQTEST1? USING LOGARCHMETH1? 'Disk:/db2log/db2logar'"

db2_all "db2 backup db cqtest1 to /db2log/backup/dpf_1,/db2log/backup/dpf_2,/db2log/backup/dpf_3,/db2log/backup/dpf_4"

db2stop

db2start

?

修改成功
