问题描述

名称很长,不过仍然不足以描述这个错误的背景。确切的描述应该是oracle用户下的ORACLE_HOME,迁移到其他位置,并将oracle属主改变为其他用户,但是oinstall组未变。随后其他oinstall组用户,无法以/ as sysdba登录数据库。
公司测试环境,ORACLE_HOME为/u01/app/oracle/product/10.2.0/db_1,将ORACLE_HOME切换到/t0/orat0/app/oracle/product/10.2.0/db_1目录下,并将ORACLE_HOME的属主从oracle改为orat0。
授权后,orat0用户直接登录就出现这个错误:

专家解答

在设置了LD_LIBRARY_PATH后,问题得以解决。但是对于除了ORACLE_HOME的OWNER外的其他oinstall用户,登录数据库就会出现同样的错误。即使设置LD_LIBRARY_PATH也不起作用。
检查后发现ORACLE_HOME/bin/oracle权限改变:

[tingkun.yang@hpserver2 bin]$ ls -l oracle
-rwxr-x--x 1 tingkun.yang oinstall 125153012 Feb 7 18:37 oracle
[tingkun.yang@hpserver2 bin]$ chmod 6751 oracle

修改文件属性后,问题依旧。

最终怀疑是ORACLE_HOME发生变化后,某些链接库的位置改变,导致Oracle运行过程中找不到一些库文件,于是以owner身份对ORACLE_HOME进行了relink all的操作:
