Thanks Matthew,  

The command you sent only write into both alert_instance_name.log under trace directory and log.xml under alert directory?

               EM 12c, EM 13c: Database Alert Log Monitoring in Enterprise Manager Cloud Control and Alert Log Metrics Explained (Doc ID 1538482.1)  

If I read the document correctly:

Alert Log > Archiver Hung Alert Log Error using alert_instance_name.log

                DB Alert Log > Archiver Hung Alert Log Error using log.xml

exec dbms_system.ksdwrt(2, 'ORA-00600: XXX');  

or whichever error message you wish to test.

You can also generate trace files.

Subject: How to test if OEM12c (12.1.0.5) detect and alert archiver hung without actually create a archive hung - production database  

Dear List,  

I setup the oracle database instance target with metric DB Alert Log > Archiver Hung Alert Log Error with Critical Threshold as ORA-.  

As Oracle document says that it "should" alert when log.xml under alert directory content the error.  

Is there the way to inject the error so that OEM will detect and send out the alert.  

It is production database so I can't not actually cause archive hung without getting fired.  

I copied the error from other database log over but doesn't seem alert.  

Thanks,

Binh
