在單分區(qū)數(shù)據(jù)庫下，如果脫機備份時遇到 SQL1035N 錯誤，說明數(shù)據(jù)庫因為處于活動（ ACTIVATE ）狀態(tài)而無法備份。可以使用 “db2 list active databases” 查詢一下實例下活動的數(shù)據(jù)庫，也可以用 “db2pd -db 數(shù)據(jù)庫名” 檢查數(shù)據(jù)庫是否處于活動狀態(tài)。
但多于多分區(qū)數(shù)據(jù)庫，脫機備份數(shù)據(jù)庫時需要注意先備份 CATALOG 節(jié)點，再備份其它節(jié)點，否則下面命令也會遇到 SQL1035N 錯誤（假設(shè)數(shù)據(jù)庫名為 SAMPLE）。

SQL1035N during execution of an offline backup
Problem
This document provides troubleshooting methods for when you attempt to take an offline backup of a database and encounter the following error: SQL1035N The database is currently in use. SQLSTATE=57019
Cause
One cause of this error is that you are attempting to take an offline backup of an activated database. This fails and returns SQL1035N.
For example, if you're using DB2? Universal Database? (DB2 UDB) Version 8.2, taking a backup of the database fails as follows:
db2 backup db sample to /home/db2inst1
SQL1035N The database is currently in use. SQLSTATE=57019
The following message is also logged in the db2diag.log file:
2005-11-18-11.29.17.849377-360 I9627A336 LEVEL: Error
PID : 34980 TID : 1 PROC : db2bp
INSTANCE: db2inst1 NODE : 000
FUNCTION: DB2 UDB, database utilities, sqlubConnectDatabase, probe:1259
DATA #1 : Hexdump, 4 bytes
0x00000001102842E0 : FFFF FBF5
....
In the above db2diag.log message, the value "FFFF FBF5" translates to -1035 (SQL1035).
Solution
You will not be able to determine whether the database is activated via the db2 list applications command, since it only tells you whether or not any applications are active on the database. To determine whether the database has been activated, you can use the following db2pd command:
db2pd -db sample -app
...
Database Partition 0 -- Database SAMPLE -- Active -- Up 0 days 00:19:42
Applications:
Address AppHandl [nod-index] NumAgents CoorPid Status Appid
...
The fact that the database has been activated is indicated by the phrase "-- Active --".
Alternatively, you can issue the command db2 list active databases.
Once the database has been deactivated (for example, via the deactivate database command), the offline backup will succeed.
2) From "DB2 Problem Determination Tutorial Series"
Version recovery - SQL1035 (database in use) when taking offline backups of all partitions in parallel The version recovery method requires loading a backup copy of the database. The database will be restored to exactly the same state that it was in when it was backed up. Using the version recovery method, you must schedule and perform full backups of the database on a regular basis.
You may have the following experience:
All database partitions are inactive at the moment. However, offline backup of all partitions in parallel fails with SQL1035N (The database is currently in use.) on most of the partitions.
You try to take offline backup of all partitions in parallel as follows:
% db2 force applications all
% db2_all ";db2 backup database sample to /database/backup"

This occurs because the database backup utility requires exclusive access to the catalog partition.
To properly backup the database in parallel, you may use the following commands:
% db2_all "<<+0<; db2 backup database sample to /database/backup"
% db2_all "<<-0<; db2 backup database sample to /database/backup"
This assumes that CATALOG PARTITION is partition 0. It is also a good illustration of why the CATALOG PARTITION should contain catalog data ONLY.
