Encountering ORA-16038, ORA-19809, and ORA-00312 errors while attempting to start the DB


Article ID: 160372


Updated On:


Data Loss Prevention Enforce Data Loss Prevention Oracle Standard Edition 2


The Database becomes unresponsive and, when attempting to start up, throws errors not unlike the following:

ORA-16038: log one sequence 3144 cannot be archived

ORA-19809: limit exceeded for recovery files

ORA-00312 online log 1 thread 1 <path to redo log file>


There may be plenty of disk space available.


Another set of symptoms can be a HTTP 404 error when logging in to the Enforce UI and in the alert_protect.log following error is found:
db_recovery_file_dest_size is 100% full.

In the Windows event viewer getting the following event.

Event Id:20
Source: Oracle
Archive process error. ORACLE Instance protect - Can not allocate log. archival required.

When listener status is checked with the command "lsnrctl status" it states:

Listening Endpoints Summary...
The listener supports no services
The command completed successfully

When connecting to the database using the following command it states;

connect protect/protect as sysdba
ORA-12514 TNS:Listener does not currently know of service requested in connect descriptor.


 The database has "archive logging" set to on. This is not supported by Broadcom support for Oracle Standard Edition databases. 


Archive logging should be turned off for Oracle Standard Edition databases.

The archive logs that are being generated have consumed all of the allocated space.  If there is still disk space available where the ORACLE_HOME is, then there is a strong likelihood that the actual log archive destination has not been set, and that Oracle is using the default destination, which is db_recovery_file_dest.  This particular directory location has a size restriction designated by db_recovery_file_dest_size.  It doesn't matter how much space is available; if the volume of the archive files exceeds the db_recovery_file_dest_size, the DB will halt.

If archiving has been turned on, then that needs to be in conjunction with an appropriate archive remediation solution.  Using archiving means that you want to create "hot backups".  

Symantec/Broadcom DLP Technical support does not support backup methods other than "cold backup".  For Oracle Enterprise Edition, a qualified DBA is necessary to establish a hot backup solution, like RMAN, that will clean up archive logs after backing them up.
