Oracle10gR2的ORA-06512 OLAP错误(转eygle)

在Oracle10gR2 10.2.0.1的Dataguard备用库启动之后，会出现以下一个错误:

Thu Aug 9 11:22:11 2007
LOGSTDBY: Validating controlfile with logical metadata
Thu Aug 9 11:22:12 2007
LOGSTDBY: Validation complete
Thu Aug 9 11:22:15 2007
Errors in file /data2/ora10g/admin/eygle/udump/eygle_ora_1372.trc:
ORA-00604: error occurred at recursive SQL level 1
ORA-12663: Services required by client not available on the server
ORA-36961: Oracle OLAP is not available.
ORA-06512: at "SYS.OLAPIHISTORYRETENTION", line 1
ORA-06512: at line 15
Completed: ALTER DATABASE OPEN

 

在对应的跟踪文件中，输出的信息如下：

Error in executing triggers on database startup
*** 2007-08-09 11:22:15.869
ksedmp: internal or fatal error
ORA-00604: error occurred at recursive SQL level 1
ORA-12663: Services required by client not available on the server
ORA-36961: Oracle OLAP is not available.
ORA-06512: at "SYS.OLAPIHISTORYRETENTION", line 1
ORA-06512: at line 15

 

提示显示，在数据库启动过程中，执行了一个和OLAP有关的Trigger，出现了错误。
检查数据库，得到以下两个相关Trigger：

SQL> select trigger_name,status from dba_triggers where trigger_name like '%OLAP%';

 

TRIGGER_NAME STATUS
------------------------------ --------
OLAPISTARTUPTRIGGER ENABLED
OLAPISHUTDOWNTRIGGER ENABLED

 

可以通过禁用这两个Trigger，防止OLAP在数据库启动和关闭时的检验，即可屏蔽这个错误信息。
Metalink上有几个Bug和这个错误相关，Bug号4630695是其中之一，这个Bug在11g中被修正。
