solaris10安装oracle10g问题

乌柒嘛黑

下面是我安装的过程
groupadd oinstal
groupadd db
useradd –d /export/home/oracle –g oinstall –G dba –m oracle
mkdir –p /opt/oracle
mkdir -p /data/oradata
chown –R oracleinstall /opt/oracle /data/oradata
设置system参数
set noexec_user_stack=1
set semsys:seminfo_semmni = 100
set semsys:seminfo_semmns = 1024
set semsys:seminfo_semmsl = 256
set semsys:seminfo_semvmx = 32767
set shmsys:shminfo_shmmax = 4294967295
set shmsys:shminfo_shmmin = 1
set shmsys:shminfo_shmmni = 100
set shmsys:shminfo_shmseg = 10
设置oracle环境变量
umask=022
ORACLE_BASE=/opt/oracle
ORACLE_HOME=/opt/oracle/10.0
ORACLE_SID=cadb
NLS_LANG=AMERICAN_AMERICA.ZHS16GBK LD_LIBRARY_PATH=$ORACLE_HOME/lib:ORACLE_HOME/network/lib:/usr/local/lib:/usr/lib:/libLD_LIBRARY_PATH
PATH=$ORACLE_HOME/bin:/usr/bin:/usr/ucb:/etc:/usr/openwin/bin:/usr/ccs/bin
export ORACLE_BASE ORACLE_HOME ORACLE_SID NLS_LANG LD_LIBRARY_PATH  PATH
安装完成后数据库和监听都建好中间没报过错
但是当我导入数据库的时候就提示：
EXP-00056: ORACLE error 1034 encountered
ORA-01034: ORACLE not available
ORA-27101: shared memory realm does not exist
Linux Error: 2: No such file or directory
EXP-00005: all allowable logon attempts failed
EXP-00000: Export terminated unsuccessfully
请问这是我那里搞错了啊？还请那位大神帮忙看看呀。。

现在又出新问题了。我重新建立数据库后就可以了。.但是我重新启动后又会这么提示..真恼火呀。.有没有人能帮帮我呀?
