Oracle数据库出现报错ORA-29701: unrecoverable error ORA-29701 raised in ASM I/O path; 这个报错一般是由于操作系统用户通过本地bequeath的方式（如sqlplus xx/xx）来连接数据库，而这个操作系统用户不在oinstall属组里面，一般情况下，比如监控，备份的情况比较多。
解决方案：1.给该操作系统用户增加oinstall属组2.第三方软件通过sqlplus mailto:xx/xx@tns]xx/xx@tns的方式连接

On 11.2.0.2 SIHA there is removal of world read/write/execute permissions on a few directories and that is intended. SOLUTION1] We recommend that the OS user that is making bequeath connection belong to oinstall group. 2] Or you can have the connection through listener.
