1. 设置ADR

## 1.1 查看v$diag_info ##

查看v$diag_info诊断库相关信息:

col value for a70
col name for a35
set linesize 140
select * from v$diag_info;

SQL> select * from v$diag_info;

   INST_ID NAME                                VALUE
---------- ----------------------------------- ----------------------------------------------------------------------
         1 Diag Enabled                        TRUE
         1 ADR Base                            /opt/app/oracle11
         1 ADR Home                            /opt/app/oracle11/diag/rdbms/vas/vas
         1 Diag Trace                          /opt/app/oracle11/diag/rdbms/vas/vas/trace
         1 Diag Alert                          /opt/app/oracle11/diag/rdbms/vas/vas/alert
         1 Diag Incident                       /opt/app/oracle11/diag/rdbms/vas/vas/incident
         1 Diag Cdump                          /opt/app/oracle11/diag/rdbms/vas/vas/cdump
         1 Health Monitor                      /opt/app/oracle11/diag/rdbms/vas/vas/hm
         1 Default Trace File                  /opt/app/oracle11/diag/rdbms/vas/vas/trace/vas_ora_10952.trc
         1 Active Problem Count                2
         1 Active Incident Count               17

11 rows selected.

1.2 ADRCI工具

ADR完全基于文件系统,可以使用ADRCI查询ADR的内容,还可以将事件和问题信息打包在可以发送给Oracle Support部门的ZIP压缩文件中。

$ adrci

ADR base = "/oradata/app/oracle"
adrci> help

2. 使用Support Workbench

2.1 手工构造一则ORA-00600错误

SQL> alter user jingyu identified by values '';
alter user jingyu identified by values ''
*
ERROR at line 1:
ORA-00600: internal error code, arguments: [kzsviver:1], [], [], [], [], [],
[], [], [], [], [], []

可以在EM中,打包问题 -> 快速打包 -> 创建新程序包 -> 查看内容 -> 查看清单 -> 调度
已成功生成程序包 ORA600kzs_20151231145006 的上载文件。
该上载文件位于 [/oradata/app/oracle/product/11.2.0/dbhome_1/ChinaUnicomDB_shitan/sysman/emd/state/ORA600kzs_20151231145006_COM_1.zip]。
请将其手动发送到 Oracle。
我们来看下这个压缩文件打包了哪些文件:

$ unzip ORA600kzs_20151231145006_COM_1.zip

  inflating: metadata.xml            

2.2 使用HM(Health Monitor)

col name for a50
select id, name, offline_capable from v$hm_check order by id;  

3. 恢复块介质

在RMAN备份命令,ANALYZE命令,dbv操作系统命令以及尝试访问受损块的SQL查询,都会找到坏块后填充v$database_block_corruption视图。
SQL> select * from v$database_block_corruption;

如果Oracle检测到受损块,它将在EM主页和警报日志中注册ORA-01578错误.错误消息包含坏块的绝对文件编号和块编号。例如:

ORA-01578: ORACLE data block corrupted (file # 5, block # 403)
ORA-01110: data file 5: '/oradata/data/SHITAN/datafile/o1_mf_dbs_d_ji_c7q2vg1x_.dbf'

通常,引起损坏的原因是操作系统或磁盘硬件故障,如存在故障的I/O硬件或固件、操作系统缓存问题、内存或分页问题或磁盘修复实用程序引发的错误。

-- 恢复5号数据文件的第403个块
RMAN> recover datafile 5 block 403;
-- 恢复v$database_block_corruption视图中记录的所有坏块
RMAN> recover corruption list;
