SP2-1503: Unable to initialize Oracle call inte易做图ce（同时装10g和11g）解决

1。现象

在11g的环境下执行 sqlplus / as sysdba 报错

SP2-1503: Unable to initialize Oracle call inte易做图ce

SP2-0152: ORACLE may not be functioning properly

2。分析

（1）在同一个AIX机器上装完10g后又装了个11g的环境

11g的环境变量配置如下（注意红色部分）

export ORACLE_BASE=/opt/oracle

export ORACLE_HOME=/oracle/product/11.2.0/

export ORA_DB=/oracle/product/11.2.0/dbs

export ORACLE_SID=ora11g

export ORACLE_TERM=vt100

export ORA_NLS33=/oracle/product/11.2.0/ocommon/nls/admin/data

export PATH=$PATH:$HOME/bin:$ORACLE_HOME/bin:.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(红色部分)

export ORACLE_HOME=/oracle/product/11.2.0

export BRARY_PATH=$ORACLE_HOME/lib:$LD_LIBRARY_PATH

（2）怀疑在执行sqlplus时调用的仍然是调用10g的，导致10g的sqlplus与11g的其他组件不兼容

$ echo $PATH

/usr/bin:/etc:/usr/sbin:/usr/ucb:/usr/bin/X11:/sbin:/usr/java5/jre/bin:/usr/java5/bin:/home/oracle/bin:/opt/oracle/product/10.1.0//bin:/home/oracle/bin:/oracle/product/11.2.0//bin:.:/home/oracle/bin:/oracle/product/11.2.0//bin:.

果然，11g的bin在10g之后。更改PATH的值，将$ORACLE_HOME/bin提前

export PATH=$ORACLE_HOME/bin:$PATH:$HOME/bin:.

$ echo $PATH

/oracle/product/11.2.0//bin:/usr/bin:/etc:/usr/sbin:/usr/ucb:/usr/bin/X11:/sbin:/usr/java5/jre/bin:/usr/java5/bin:/home/oracle/bin:/opt/oracle/product/10.1.0//bin:/home/oracle/bin:/oracle/product/11.2.0//bin:.:/home/oracle/bin:.

3。验证通过

$ sqlplus / as sysdba
