Oracle 执行netca 时报错 An unexpected exception has been detected in native code outside the VM 的解决方案
安装好oracle 10后，配置网络监听，执行 netca ，报错如下：

错误的原因是未在 /etc/hosts 文件中添加hostname对应的ip地址。
解决：
查看主机名shell下执行 hostname 譬如 hostnameAAA
查看ip地址，执行ifconfig 譬如 xxx.xxx.x.xxx
vi /etc/hosts
在 127.0.0.1 这一行的下面添加一行：
XXX.XXX.X.XXX hostnameAAA
保存即可。
怎样解决ORA-01078 & LRM-00109错误
SQL> startup
ORA-01078: failure in processing system parameters
LRM-00109: could not open parameter file '/opt/oracle/products/10.1.0.3/db_1/dbs/initrawdb.ora'
解决办法：
cp $ORACLE_BASE/admin/$ORACLE_SID/pfile/init.ora /opt/oracle/products/10.1.0.3/db_1/dbs/initrawdb.ora

问题解决！
注：Oracle在启动过程中,需要读取参数文件(pfile/spfile)来创建实例.Oracle在启动过程中,寻找参数文件的顺序为:spfile.ora,spfile.ora,init.ora.
问题补充：错误信息：
SQL> conn sys/oracle@xzomc as sysdba

SQL> startup pfile=/oracleapp/u01/app/oracle/admin/xzomc/pfile/initgomcr.ora

也可能是oracle_sid的问题，问题出在设置oracle用户.bash_profile文件的oracle_sid变量时，写为了 oracle_sid=wilson ，在startup的时候报错，其实真正的数据库实例名称是venus。
