实例已经运行了，但Oracle用户和root用户看到的结果不一样，为什么？

问题已处理！
由于ORACLE_BASE环境变量设置导致数据库连接异常：
[oracle@db1 ~]$ cat .bash_profile
# .bash_profile

# Get the aliases and functions
if [ -f ~/.bashrc ]; then
        . ~/.bashrc
fi

# User specific environment and startup programs

PATH=$PATH:$HOME/bin
export ORACLE_BASE=/u01/app/oracle/
export ORACLE_HOME=$ORACLE_BASE/product/10.2.0/db_1
export ORA_CRS_HOME=$ORACLE_BASE/product/10.2.0/crs_1
export ORACLE_SID=zddb1
export PATH=$ORACLE_HOME/bin:$ORA_CRS_HOME/bin:$PATH:$HOME/bin

将其设置为“export ORACLE_BASE=/u01/app/oracle”，数据库连接正常。
