教您如何实现DB2表空间扩容_DB2_数据库_程序员俱乐部

DB2表空间扩容是我们在使用DB2数据库中的常见操作，下面就为您详细介绍几种DB2表空间扩容的方法，希望对您能有所启迪。

多所有容器扩容

db2 " ALTER TABLESPACE tablespace-name EXTEND (ALL 1000000)"

DB21034E The command was processed as an SQL statement because it was not avalid Command Line Processor command. During SQL processing it returned:

SQL1139N The total size of the table space is too big. SQLSTATE=54047
 
对其中一个容器扩容

db2 " ALTER TABLESPACE tablespace-name  EXTEND (FILE '/dir/filename' 3000000)"

DB21034E The command was processed as an SQL statement because it was not avalid Command Line Processor command. During SQL processing it returned:

SQL1139N The total size of the table space is too big. SQLSTATE=54047
 
加容器

db2 " ALTER TABLESPACE tablespace-name  ADD (FILE '/dir/filename' 500000)"

DB21034E The command was processed as an SQL statement because it was not avalid Command Line Processor command. During SQL processing it returned:

SQL1139N The total size of the table space is too big. SQLSTATE=54047
 
通过检查可以看到
