Ora-1157 ora-1110错误解决案例一枚

1、数据库打开报错如下： SQL> alter database open; alter database open * ERROR at line 1: ORA-01157: cannot identify/lock data file 4 - see DBWR trace file ORA-01110: data file 4: '/weblogic/oradata/orcl/users01.dbf' 2、查看告警日志，同样报错： Thu Nov 10 17:58:14 2016 alter database open Thu Nov 10 17:58:14 2016 Errors in file /u01/app/oracle/diag/rdbms/orcl/orcl/trace/orcl_dbw0_22383.trc: ORA-01157: cannot identify/lock data file 4 - see DBWR trace file ORA-01110: data file 4: '/weblogic/oradata/orcl/users01.dbf' ORA-27041: unable to open file Linux-x86_64 Error: 13: Permission denied Additional information: 9 Errors in file /u01/app/oracle/diag/rdbms/orcl/orcl/trace/orcl_dbw0_22383.trc: ORA-01157: cannot identify/lock data file 5 - see DBWR trace file ORA-01110: data file 5: '/weblogic/oradata/orcl/users02.dbf' ORA-27041: unable to open file Linux-x86_64 Error: 13: Permission denied Additional information: 9 Errors in file /u01/app/oracle/diag/rdbms/orcl/orcl/trace/orcl_ora_24033.trc: ORA-01157: cannot identify/lock data file 4 - see DBWR trace file ORA-01110: data file 4: '/weblogic/oradata/orcl/users01.dbf' ORA-1157 signalled during: alter database open... 3、因为报错linux错误，所以查看具体的数据文件权限，发现数据文件权限都变成了weblogic： [root@slave1 weblogic]# ll total 24 drwx------. 2 weblogic weblogic 16384 May 6 2016 lost+found drwxrwxr-x. 3 weblogic weblogic 4096 May 6 2016 Oracle drwxr-xr-x. 3weblogic weblogic 4096 Aug 16 10:20 oradata 4、修改数据文件权限： [root@slave1 weblogic]# chown -R oracle:oinstall Oracle/ [root@slave1 weblogic]# chown -R oracle:oinstall oradata/ [root@slave1 weblogic]# ll total 24 drwx------. 2 weblogic weblogic 16384 May 6 2016 lost+found drwxrwxr-x. 3 oracle oinstall 4096 May 6 2016 Oracle drwxr-xr-x. 3 oracle oinstall 4096 Aug 16 10:20 oradata 5、成功打开数据库，告警日志也没有再次报错： SQL> alter database open; Database altered.
