Hello
DB17 is not really related to monitoring, it's got more to do with daily checks.
It is a maintenance view for table DBCHECKORA (Configuration of Database Check).
This table allows to set option / thresholds for the controls performed by Br*Tools checks (Brconnect -u / -c -f check).
I do not think there is such an maintenance screen in NWA.
If you have installed your Java stack with MCOD (both stack share the same database, using different schema), the Br*Tools of the ABAP stack will do the job.
I do not have a Java stack running on a standalone DB, but as far as BR*Tools are installed with the Java stack it is possible to run the Br*Tools check and maintain table DBCHECKORA directly with SQL command.
Take a look at the attachment of note 403704 - BRCONNECT - Enhanced functions for Oracle DBA
it contains scripts to rebuild the content of table DBCHECKORA
[...]
DELETE FROM DBCHECKORA;
INSERT INTO DBCHECKORA (TYPE, PARAM, OBJECT, ACTIVE, SEVERITY, CHKOP, CHKVAL, UNIT, CHKREP, REPUNIT, MODFLAG, MODDATE, MODUSER, REACTION, CORRTYPE, CORRNAME, CHKDESC) VALUES ('DBA', 'ARCHIVER_STUCK', ' ', 'Y', 'W', '>', '90', 'P', ' ', ' ', ' ', ' ', ' ', ' ', 'D', 'Save and delete archive log files', 'Out of space in archive directory');
INSERT INTO DBCHECKORA (TYPE, PARAM, OBJECT, ACTIVE, SEVERITY, CHKOP, CHKVAL, UNIT, CHKREP, REPUNIT, MODFLAG, MODDATE, MODUSER, REACTION, CORRTYPE, CORRNAME, CHKDESC) VALUES ('DBA', 'CONTROL_FILE_MIRROR', ' ', 'Y', 'E', ' ', ' ', ' ', ' ', ' ', ' ', ' ', ' ', ' ', 'D', 'Extend CONTROL_FILES parameter', 'Control file not mirrored');

Hope this helps...
