An example of DB2 data recovery: SQL0928N

The environment is AIX 6.1 and DB2 9.7.0.7.
First, check whether the db2 master process exists.
 
Ps-ef | grep db2sys
 
If the database does not exist, use db2start to open the database.
 
The backup media is a cold backup data source,
 
Cd to the directory where the media is located:
 
Cd/home/db2inst1/backup
 
Use the redirect parameter to change the directory:
 
1.> db2 restore db xxx from. replace existing redirect without rolling forward
 

SQL1277W A redirected restore operation is being stored med. Table space
 
Configuration can now be viewed and table spaces that do not use automatic
 
Storage can have their containers reconfigured.
 
DB20000I The restore database command completed successfully.
 

 

List xxx database container details:
 
2.> db2pd-db xxx-tablespaces
 

Database Partition 0 -- Database xxx -- Active -- Up 0 days 00:00:16 -- Date 2014-05-07-13.06.01.022471

Create a storage path for the xxx database container in the/db2sys directory:
 
Cd/db2sys/db2inst1
 
Mkdir xxx
 
3. Change the storage path of containers and files:
 

Db2 "set tablespace containers for 0 using (Path '/db2sys/db2inst1/xxx/NODE0000/SQL00001/SQLT0000.0 ')"
 
Db2 "set tablespace containers for 1 using (Path '/db2sys/db2inst1/xxx/NODE0000/SQL00001/SQLT0001.0 ')"
 
Db2 "set tablespace containers for 2 using (Path '/db2sys/db2inst1/xxx/NODE0000/SQL00001/SQLT0002.0 ')"
 
Db2 "set tablespace containers for 3 using (Path '/db2sys/db2inst1/xxx/NODE0000/SQL00001/SYSTOOLSPACE ')"
 
Db2 "set tablespace containers for 4 using (Path '/db2sys/db2inst1/xxx/NODE0000/SQL00001/SYSTOOLSTMPSPACE ')"
 
Db2 "set tablespace containers for 5 using (File '/db2sys/db2inst1/xxx/NODE0000/SQL00001/CDTABLESPACE. DAT' 50000 )"
 
Db2 "set tablespace containers for 6 using (File '/db2sys/db2inst1/xxx/NODE0000/SQL00001/TSASNCA' 38400 )"
 
Db2 "set tablespace containers for 7 using (File '/db2sys/db2inst1/xxx/NODE0000/SQL00001/TSASNUOW' 12800 )"
 
Db2 "set tablespace containers for 8 using (Path '/db2sys/db2inst1/xxx/NODE0000/SQL00001/xxxclob ')"
 

 

Ps: One SQL0298N error is reported:
 
SQL0298N Bad container path. SQLSTATE = 428B2
 
The specified container type and container name are correct. I couldn't find a way at the end, and finally used a clumsy method;
 
Solution:
 
Delete xxx database:
 

> Db2 drop db xxx
 
Use db2 restore again to restore and add the to parameter:
 
> Db2 restore db xxx from. on/db2sys/db2inst1/xxx replace existing redirect without rolling forward
 
Repeat the preceding command to change the container and data file path.
 
After the path is changed, restore continue:
 
> Db2 restore db xxx continue
 
DB20000I The restore database command completed successfully.
 

 

Change archive path
 
> Db2 update db cfg for xxx using LOGARCHMETH1 disk:/db2sys/db2log/xxx
 

 

Restart the database to make the parameters take effect:
 
> Db2 stop
 
> Db2 start
 

 

Ps: SQL0332N during db2 connect
 

> Db2 connect to xxx
 
SQL0332N Character conversion from the source code page "1386" to the target
 
Code page "819" is not supported. SQLSTATE = 57017
 
Solution:
 
> Db2set
 
DB2COMM = tcpip
 

 

> Db2set DB2CODEPAGE = 1386
 

 

> Db2set
 

DB2COMM = tcpip
 
DB2CODEPAGE = 1386
 
> Db2 terminate
 

 


> Db2 connect to cnap
 

 

Database Connection Information
 

 

Database server = DB2/AIX64 9.7.7
 
SQL authorization ID = DB2INST1
 
Local database alias = XXX
 

 

OK, DB2 is restored.
