使用的命令：
db2 list tablespaces show detail
db2 list tablespace containers for [Tablespace ID] [show detail]
说明：在语句末尾添加show detail，则能查看表空间大小以及使用的信息
以下是具体实现案例：
在日常使用db2的过程中，有时候我们需要查询db2表空间所存储的位置来判断磁盘空间是否还够用，下面为查询表空间TEMPTS16K的位置
db2inst1@Linux:/opt> db2 list tablespaces show detail
Tablespaces for Current Database
Tablespace ID = 0
Name = SYSCATSPACE
Type = Database managed space
Contents = All permanent data. Regular table space.
State = 0x0000
Detailed explanation:
Normal
Total pages = 24576
Useable pages = 24572
Used pages = 22552
Free pages = 2020
High water mark (pages) = 22552
Page size (bytes) = 4096
Extent size (pages) = 4
Prefetch size (pages) = 4
Number of containers = 1
Tablespace ID = 1
Name = TEMPSPACE1
Type = System managed space
Contents = System Temporary data
State = 0x0000
Detailed explanation:
Normal
Total pages = 1
Useable pages = 1
Used pages = 1
Free pages = Not applicable
High water mark (pages) = Not applicable
Page size (bytes) = 4096
Extent size (pages) = 32
Prefetch size (pages) = 32
Number of containers = 1
Tablespace ID = 2
Name = USERSPACE1
Type = Database managed space
Contents = All permanent data. Large table space.
State = 0x0000
Detailed explanation:
Normal
Total pages = 49152
Useable pages = 49120
Used pages = 45984
Free pages = 3136
High water mark (pages) = 45984
Page size (bytes) = 4096
Extent size (pages) = 32
Prefetch size (pages) = 32
Number of containers = 1
Tablespace ID = 3
Name = TEMPTS16K
Type = System managed space
Contents = System Temporary data
State = 0x0000
Detailed explanation:
Normal
Total pages = 1
Useable pages = 1
Used pages = 1
Free pages = Not applicable
High water mark (pages) = Not applicable
Page size (bytes) = 16384
Extent size (pages) = 32
Prefetch size (pages) = 32
Number of containers = 1
db2inst1@Linux:/opt> db2 list tablespace containers for 3
Tablespace Containers for Tablespace 3
Container ID = 0
Name = /db2home/db2inst1/db2inst1/NODE0000/QINDB/T0000003/C0000000.TMP
Type = Path
从上述显示结果我们可以看出，表空间TEMPTS16K对应的物理文件路径为：/db2home/db2inst1/db2inst1/NODE0000/QINDB/T0000003/C0000000.TMP
