SYMPTOMS
Getting the following error message when trying to use the SQl Monitoring page:
java.sql.SQLException: ORA-31061: XDB error: special char to escaped char conversion failed.
ORA-06512: at "SYS.DBMS_SQLTUNE", line 15487
ORA-06512: at "SYS.DBMS_SQLTUNE", line 15596
ORA-06512: at line 1
The issue is not persistent but re-appaer several times per day.
CAUSE
This error is reported because some illegal character exists in source data.. It is the correct behavior.
Workaround is to remove or replace the illegal character/s. However sometimes it may be hard to find where the illegal character comes from.
Bug 8246403 adds new functionality to replace illegal characters instead of raising ORA-31011 error.
SOLUTION
To fix this problem first apply database Patch 8246403 corresponding to your platform and DB version. If the patch does not exist then contact Oracle Support to request a new patch for your platform and DB version.
Note: If you are on 10.2.0.5 or 11.2 or higher version then you don‘t need this patch as it is already included in this release.
This Bug:8246403 is an XDB enhancement to add functionality to replace illegal characters instead of raising ORA-31011 error. This enhancement is protected by event 19119 and is disabled by default. This functionality is controlled by setting following levels under event 19119 -
- level 0x100000 : replace illegal character with "?"
- level 0x200000 : replace illegal character with character reference, i.e "&#x%04x;"
- level 0x400000 : remove the illegal character
To enable the event at a particular level perform the below steps -
SQL> ALTER SYSTEM SET EVENTS ‘19119 trace name context forever, level 0x100000‘;
or
Activate the event by adding it to the INIT.ORA parameter file -
event="19119 trace name context forever, level 0x100000"
restart the database for the event to take affect.
The above event setting will replace the illegal character with "?" and will allow your operation to complete without error.代码100分
