数据库日志中发现以下错误信息：

Errors in file /home/oracle/app/oracle/admin/orcl/udump/orcl_ora_672044.trc:
ORA-00600: internal error code, arguments: 
[unable to load XDB library], [], [], [], [], [], [], []

Dynamic link error:     0509-022 Cannot load 
module /home/oracle/app/oracle/product/920/lib32/libxdb.so.
        0509-103   The module has an invalid magic number.

在Metalink上搜了一把，发现原来跟环境变量有关（759401.1）：

On AIX5L, LIBPATH needs to be configured and 
the 64-bit library path ($ORACLE_HOME/lib) should be 
placed before the 32-bit library path ($ORACLE_HOME/lib32).

设置变量时，将$ORACLE_HOME/lib摆在前面就行了：

export LD_LIBRARY_PATH=$ORACLE_HOME/lib:$ORACLE_HOME/lib32:<other paths>
export LIBPATH=$ORACLE_HOME/lib:$ORACLE_HOME/lib32:</other><other paths>
</other>
