教您如何實(shí)現(xiàn)DB2表空間擴(kuò)容
DB2表空間擴(kuò)容是我們?cè)谑褂?a >DB2數(shù)據(jù)庫中的常見操作，下面就為您詳細(xì)介紹幾種DB2表空間擴(kuò)容的方法，希望對(duì)您能有所啟迪。
多所有容器擴(kuò)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
對(duì)其中一個(gè)容器擴(kuò)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
通過檢查可以看到
LIST TABLESPACES SHOW DETAIL
...
Tablespace ID = 8
Name = tablespace-name
Type = Database managed space
Contents = Any data
State = 0x0000
Detailed explanation:
Normal
Total pages = 16388000
Useable pages = 16387840
Used pages = 16387840
Free pages = 0
High water mark (pages) = 16387840
Page size (bytes) = 4096
Extent size (pages) = 32
Prefetch size (pages) = 128
Number of containers = 4
Minimum recovery time =2009-06-26-04.47.15.000000
