linux下配置Oracle出现问题

搞了好久，可以用sql /nolog进入了。但是后续配置出现问题。监听创建不来。netcat命令出错。
1.图形安装netcat 命令
2.静默安装netca /silent /responsefile /data/oracle/database/response/netca.rsp
都报错，如下：
Oracle Net Services 配置:
An unexpected exception has been detected in native code outside the VM.
Unexpected Signal : 11 occurred at PC=0xF765EAC6

NOTE: We are unable to locate the function name symbol for the error

PS：感觉是libc.so.6库没安装。用yum install libc.so.6 运行了一下，显示已安装。
百度了许久，未能解决。跪求！是什么原因？

Answer 1

1、你先确定linux系统版本，按文档安装oracle依赖包。例如gcc/glibc/libaio/libstdc/libgcc/openmotif/compat-libstdc/elfutils-libelf/compat-libstdc
2、准备系统环境参数，创建oracle分组及用户，修改系统文件，例如：/etc/sysctl.conf，/etc/security/limits.conf，/etc/profile,/etc/pam.d/login,~/.bash_profile
3、静默方式安装oracle数据库
./runInstaller -ignoreSysPrereqs -silent -responseFile ~/ee.rsp
4、创建实例
dbca -silent -createDatabase -templateName General_Purpose.dbc -gdbname testdb -sid testdb -responseFile NO_VALUE -characterSet AL32UTF8 -memoryPercentage 40 -sysDBAUserName sys -sysDBAPassword 123456(不启动em)
增加-emConfiguration none（启动em）
dbca静默删除数据库
dbca -silent -deleteDatabase -sourceDB mydb -sysDBAUserName sys -sysDBAPassword db123456
5、启动监听lsnrctl start;
6、启动数据库
sqlplus /nolog
SQL>conn /as sysdba
SQL>startup;
7、关闭数据库
sqlplus /nolog
SQL>conn /as sysdba
SQL>shutdown immediate
8、netca是创建listener.ora或tnsnames.ora的工具，这两个文件手动编辑或创建即可，没有也不影响数据库启动。不需要借助此命令。
