DB2数据迁移之load

发表于 2012 年 4 月 15 日 由 惜分飞

一.load原理性知识
1.为什么要使用LOAD
load不需要写日志(或很少日志),不做检查约束和参照完整性约束,不触发Trigger,锁的时间比较短,因此特别适合大数据量的导入.

2.load过程分为4个阶段
load/build/delete/index copy.
load阶段是将源文件parser成物理数据存储的格式,直接装入到页中,而不通过db2引擎,load阶段会检查表定义,违背定义的数据不会装入到表中.
build阶段建议索引（如果装入表有索引的话）,会检查唯一性约束,违背了唯一性的数据会在delete阶段删除.
index copy阶段将index数据从指定的临时表空间拷贝到初始的表空间里.
index copy只适应于allow read access场景.load的4个阶段会记录在messages文件里.

3.load的offline和online
缺省情况下,load过程不允许其他应用访问表,即allow no access,或叫offline load（离线加载）.Allow read access,或叫online load(在线加载）,只有在load …insert into的时候才允许使用,其他应用读到的数据是加载前的数据,load … replace into会将数据先删除,再load,只能是离线加载.

4.load表的状态
load可能出现的几种状态,某一时刻可能会同时处于几种状态.只有当表是normal状态时,表才能进行正常的增删改查操作.
normal: 正常状态
set integrity pending: 如果目标表有check约束或reference约束,那么Load后此表处于set integrity pending,表明表有约束还未检查,稍后解释.
load in progress:load正在数据加载过程中.
load pending:数据提交前出现了故障,需要通过load..terminate,load..replace或load..restart解除暂挂状态
read access only:目标表数据是可以读的,当load时指定了allow read access,那表就会处于read access only状态
unavailable:表可能被删除了或从backup中恢复了.
unknown:通过load..query命令无法得知表的状态.

二.load试验测试

补充说明
1.chardel 指定字符串分隔符,默认是””
2.lobs to path　指定lob目录,modified by lobsinfile 指定保存一个文件;modified by lobsinsepfiles 指定每个值保存一个文件
3. into table_name指定表导入数据方式:inset(追加),insert_update(有主键,主键匹配更新,否则增加),replace(删除表数据,然后插入)
4.commitcount 和数据库提交相关,默认是automatic:db2内部自动计算什么时候提交
5.restartcount/skipcount N 表示跳过前N条记录,从N+1开始继续导入
6.rowcount N 表示插入条数

[db2inst2@xifenfei ~]$ db2 "import from /home/db2inst1/sample.act of del restartcount  10

7.补充说明
1)在升级数据库前需要做好数据库和软件备份
2)升级过程时先关闭所有db2相关进程,如果不能正常关闭(非本文上面列举操作相关进程),直接kill
3)升级过程中,如果实例,DAS等升级失败,需要后续手工升级
4)检查相关进程,如果没有正常启动,需要手工给予启动
5)一些工具进行绑定和重新绑定packages
