You Asked

can i start logminer once across one connection, reuse it in realtime. meaning that the V$LOGMNR_CONTENTS view gets updated in realtime without having to end logminer session and build it again?
Thank you

and we said...

Not real time, but you can do DBMS_LOGMNR.ADD_LOGFILE whenever you want in a session, even if you have already started log miner, and you do not have to do an END.

ie, you can do:


and query V$LOGMNR_CONTENTS and then do


without needing to run dbms_logmnr.end_logmnr

You might see a "CONTINUOUS_MINE" option in the docs which automatically add log files. I'd recommend against that because it is de-supported in later releases.

12c deprecated.
19c desupported.

start_time / end_time are optional - and thus you should be able to mine all logfiles that you have added via "add_logfile"
