ORA-27468 EXFSYS.RLM$EVTCLEANUP任务引起的故障

客户的数据库中遇到如下错误:
Errors in file /oracle/admin/cdx/bdump/cdx2_j000_663594.trc:
ORA-12012: error on auto execute of job 42780
ORA-27468: "EXFSYS.RLM$EVTCLEANUP" is locked by another process

伴随这个错误还出现了大量的ORA-04031 错误:

数据库中的这些JOB是做什么的呢?
These jobs under EXFSYS schema are related to the Expression Filter feature in 10G.
The Expression Filter feature can be installed on an Oracle10G Standard or Enterprise Edition
database. It is supplied as a set of PL/SQL packages, a Java package, a set of dictionary tables,
and catalog views. All these objects are created in a dedicated schema named EXFSYS. This schema
is not part of the typical installation of the database and will not exist before the Expression Filter is installed.

如果数据库不使用这个特性,可以Disable EXFSYS模式:

1. Login as SYSDBA
2. @$ORACLE_HOME/rdbms/admin/catnoexf.sql

参考Metalink: 444766.1

诊断故障时,可以手工执行任务:
BEGIN
    dbms_scheduler.run_job(job_name => 'EXFSYS.RLM$EVTCLEANUP', use_current_session => FALSE);
END;
/
可以通过10046事件跟踪诊断其具体不能完成之原因,更改use_current_session=>TRUE测试(参考Metalink Note: 473551.1)。
