我的db8.2安装经历

1、从IBM网上下载db8.2

2、在图形界面下运行./db2setup，next就可以了

3、运行db2start,报roblem
Message SQL6048N is reported when starting WebSphere Voice Response, because DB2 is not running. However, issuing a
db2start command also fails.

The following errors are displayed from db2start:

exec(): 0509-036 Cannot load program db2stop because of the
following errors:
0509-130 Symbol resolution failed for /usr/lib/threads/libc.a?aio_64.o

0509-026 System error: Cannot run a file that does not have a valid

sigh

从google上查到是AIO的原因。

This is a known problem for DB2 Version 8 when Kernelised Asynchronous I/O (KAIO) is not enabled. 
 
Solution
To enable KAIO:
1. Log in as root
2. Enter smitty aio
3. Select "Change / Show Characteristics of Asynchronous I/O"
4. Set the "STATE to be configured at system restart" field to "available"
5. Reboot AIX.

然后在运行db2start有出现SQL10007N Message "-1390" could not be retrieved.  Reason code: "6".
上CU上向CUser询问，感谢yufengsh 

说的是license的问题，让我留下mail,发license给我，好人啊！！

明天等邮件吧继续安装。^_^
