数据库系统:Oracle 10g r2

安装的时候把系统80%的内存都分配给oracle数据库(大概是10G左右)

问题:

在/data目录建表空间
1G需要时间为2分多钟
2G需要时间为5分多钟

在/oradata目录建表空间
1G需要时间为5分多钟
2G需要时间为10分多钟

在本机的window系统下安装oracle 11g,,

创建表空间1G大概15到20秒,2G大概30到40秒左右。

为什么在hp-ux上创建表空间会那么慢呢?

具体在hp-ux上简表过程如下:

$ vi create_tablespace.sh
"create_tablespace.sh" 10 lines, 395 characters
#!/bin/sh
echo "===========start date:`date` ============"
sqlplus / as sysdba create tablespace test1 datafile '/data/test1.dbf' size 1024M;
quit;
EOF
echo "===========end date:`date`==============="
$ ./create_tablespace.sh
===========start date:Mon Dec  5 10:55:48 EAT 2011 ============
