DB2 菜一(折腾DB2 V8)

db2start

db2cmd

db2

db2 => create database smart_crud
SQL1001N  "smart_crud" is not a valid database name.  SQLSTATE=2E000

db2 => create database smartcru (MB的,db2数据库名的长度只能是8位?)
SQL1047N  The application is already connected to another database.

db2 => connect reset
DB20000I  The SQL command completed successfully.

db2 => create database smartcru
DB20000I  The CREATE DATABASE command completed successfully.

就这么建成功了,默认建哪里去了?
db2 => list database directory [on 盘符:]

db2 =>

好吧,看起来有5个数据库,然后具体位置在E:\db2\NODE0000,有6个目录,目录的结构大致如下:

E:\db2\NODE0000>tree
Folder PATH listing for volume software
Volume serial number is F439-30CD
E:.
├─SQL00001
│  ├─DB2EVENT
│  │  └─db2detaildeadlock
│  ├─SQLOGDIR
│  ├─SQLT0000.0
│  ├─SQLT0002.0
│  └─SYSTOOLSPACE
├─SQL00002
│  ├─DB2EVENT
│  │  └─db2detaildeadlock
│  ├─SQLOGDIR
│  ├─SQLT0000.0
│  ├─SQLT0001.0
│  ├─SQLT0002.0
│  └─SYSTOOLSPACE
├─SQL00003

通过文件的创建时间能隐约看出来,这个新建的DB位置在:E:\db2\NODE0000\SQL00005

又建了一个create database notsmart,这次默认的位置在E:\db2\NODE0000\SQL00006,
看了一个这个生成的目录的大小,约30M

db2 => drop database notsmart
DB20000I  The DROP DATABASE command completed successfully.

这次创建DB的时候带点参数:
db2 => create database notsmart on 'E:/db2data/notsmart/on1','E:/db2data/notsmar
t/on2'
SQL0104N  An unexpected token "," was found following "<character-string>".
Expected tokens may include:  "CATALOG".  SQLSTATE=42601
db2 => create database notsmart on 'E:/db2data/notsmart/on1'
SQL1052N  The database path "E:/db2data/notsmart/on1" does not exist.
db2 =>

好吧。我手动的把目录先建好。

db2 => create database notsmart on 'E:/db2data/notsmart/on1'
SQL1052N  The database path "E:/db2data/notsmart/on1" does not exist.

TMD的,还是这个错:

看这里:http://blog.csdn.net/xuyingjun/article/details/6430259

E:\db2data\notsmart>db2set -i db2 DB2_CREATE_DB_ON_PATH=YES

DBI1302E Invalid parameter detected.

Explanation:

An invalid parameter was used.

User Response:

Use the -? option for the usage help message.

为什么不可以? 难道DB2 8不支持这个变量吗?为了少折腾,我还是升级先。
