# Example INIT.ORA file
#
# This file is provided by Oracle Corporation to help you customize
# your RDBMS installation for your site. Important system parameters
# are discussed, and example settings given.
#
# Some parameter settings are generic to any size installation.
# For parameters that require different values in different size
# installations, three scenarios have been provided: SMALL, MEDIUM
# and LARGE. Any parameter that needs to be tuned according to
# installation size will have three settings, each one commented
# according to installation size.
#
# Use the following table to approximate the SGA size needed for the
# three scenarious provided in this file:
#
# -------Installation/Database Size------
# SMALL MEDIUM LARGE
# Block 2K 4500K 6800K 17000K
# Size 4K 5500K 8800K 21000K
#
# To set up a database that multiple instances will be using, place
# all instance-specific parameters in one file, and then have all
# of these files point to a master file using the IFILE command.
# This way, when you change a public
# parameter, it will automatically change on all instances. This is
# necessary, since all instances must run with the same value for many
# parameters. For example, if you choose to use private rollback' segments,
# these must be specified in different files, but since all gc_*
# parameters must be the same on all instances, they should be in one file.
#
# INSTRUCTIONS: Edit this file and the other INIT files it calls for
# your site, either by using the values provided here or by providing
# your own. Then place an IFILE= line into each instance-specific
# INIT file that points at this file.
#
# NOTE: Parameter values suggested in this file are based on conservative
# estimates for computer memory availability. You should adjust values upward
# for modern machines.

看上去，好象没有超过我的SGA嘛，后来将其中的INITIAL行注释掉，换成SMALL行的配置，再以startup nomount;重启动成功，但是以startup;启动提示找不到CONTROL文件，看了一下CONTROL文件确实没有。
用dbassist将该数据库删除，再重建，发现用TYPICAL方式建立库时有两个选择，1。从光盘拷贝，这是一种快速的建库方法，也就是我初始安装ORACLE时选择的模式，2。create a new database，时间比较长，但是经过的alert提示也更加多，我没有办法再这样一直IGNORE下去了，只好又选择了第一种模式，发现情况还是一样的。怎么会这样，难道我的512M内存不适合装ORCLE8。1。7吗？
