If the database designer has created a Primary partition Index on a table, queries should incorporate the partitioning column.
如果数据库设计者已在表上创建了主分区索引,那么查询应当与分区列结合。
A partitioning key is a column (or group of columns) that is used to determine the partition in which a particular row of data is stored.
分区键是用于确定特定一行数据存储在哪个分区的一个列(或一组列)。
Reorganizing a partition will put the entire table offline if the partitioned table has any global indexes besides XML column path indexes.
如果已分区表包含任何xml列路径索引以外的其他全局索引,重组一个分区会导致整个表脱机。
If the RANDOM column is used to determine the partition location of a table row.
如果random列用于确定一个表行的分区位置。
Selecting certain values of the Partnum column causes a window to pop up that displays the partition information for the respective value.

To pin a logical database partition to a NUMA pod, you enter the NUMA pod number in the resourcesetname column in the db2node.cfg file.
要将逻辑数据库分区与NUMApod 相关联,需要在db2node.cfg文件 中的resourcesetname列输入 NUMA pod号。
The placement is determined by an internal hashing function that takes the values in the column or columns defined as a partitioning key and returns the database partition number.
这种安置是由一个内部的哈希函数决定的,该函数接受定义为分区键的列内的值并返回数据库分区号。
