在使用非ORACLE使用者登入資料庫時出現如報錯：

[[email protected] ~]$ sqlplus "/as sysdba"

SP2-0157: unable to CONNECT to ORACLE after 3 attempts, exiting SQL*Plus

這個時候檢查bin目錄下的oracle執行程式許可權如下

[[email protected] ~]$ ls -lrt $ORACLE_HOME/bin/oracle
-rwxr-x--x. 1 oracle oinstall 112701117 Dec  6 17:28 /u01/app/oracle/product/10.2.0/db_1/bin/oracle
[[email protected] ~]$ id
uid=504(marven) gid=501(oinstall) groups=501(oinstall),502(dba)

使用root使用者修改為如下即可：
[[email protected]

~]$ su
Password:
[[email protected] oracle]# chmod 6755 $ORACLE_HOME/bin/oracle
[[email protected] oracle]# ls -lrt $ORACLE_HOME/bin/oracle
-rwsr-sr-x. 1 oracle oinstall 112701117 Dec  6 17:28 /u01/app/oracle/product/10.2.0/db_1/bin/oracle
[[email protected] oracle]# exit
登入成功：
[[email protected] ~]$ sqlplus "/as sysdba"
