一、建表空间和数据库
1.在db2ad、db2db和db2ap上均执行:
[sql] view plaincopyprint?
- db2set db2comm=tcpip
- db2set db2codepage=1386
db2set db2comm=tcpip
db2set db2codepage=1386
2.新建数据库:
[sql] view plaincopyprint?
- db2 create db <dbname> using codeset gbk territory CN collate using identity
db2 create db <dbname> using codeset gbk territory CN collate using identity
3.连接上数据库:
[sql] view plaincopyprint?
- db2 "connect to <dbname>"
db2 "connect to <dbname>"
4.创建缓冲池 + 建立表空间;
1).删除旧的表空间:
[sql] view plaincopyprint?
- db2 drop tablespace tablespace1, tablespace2, tablespace3
db2 drop tablespace tablespace1, tablespace2, tablespace3
2).新建缓冲池:
[sql] view plaincopyprint?
- db2 create bufferpool bp32k all nodes size -1 pagesize 32k
db2 create bufferpool bp32k all nodes size -1 pagesize 32k
bp32k为该缓冲池的名称;
32K为页大小;
size=-1表示使用缺省的buffpage,而buffpage可以通过db2 get db cfg|grep -i buff参数查看到;
3).新建表空间:
[sql] view plaincopyprint?
- db2 "create regular tablespace tablespace1 pagesize 32k managed by database using(file '/usr/yixiayizi/tablespace1' 5g) bufferpool bp32k"
- db2 "create regular tablespace tablespace2 pagesize 32k managed by database using(file '/usr/yixiayizi/tablespace2' 10g) bufferpool bp32k"
- db2 "create regular tablespace tablespace3 pagesize 32k managed by database using(file '/usr/yixiayizi/tablespace3' 2g) bufferpool bp32k"
db2 "create regular tablespace tablespace1 pagesize 32k managed by database using(file '/usr/yixiayizi/tablespace1' 5g) bufferpool bp32k"
db2 "create regular tablespace tablespace2 pagesize 32k managed by database using(file '/usr/yixiayizi/tablespace2' 10g) bufferpool bp32k"
db2 "create regular tablespace tablespace3 pagesize 32k managed by database using(file '/usr/yixiayizi/tablespace3' 2g) bufferpool bp32k"
注意(file '/usr/yixiayizi/tablespace1' 5g)的设置:
第一个参数:
当指向外置盘时,file改为device;
当指向文件路径时,为file;
第二个参数:需要是绝对路径;
第三个参数:该表空间的大小;
