But as soon as all of the subscribed tables are processed, the DBMS_LOGMNR_CDC_PUBLISH.PURGE procedure purges all of the appropriate rows from all of the capture tables.
Does anyone know of anyplace I can get more detailed information on how the CDC process works in 9i?
I had no trouble with 1 capture table, but as soon as I added a second I noticed that even after I did a manual purge the entries in the capture table were not going away until much later.
Oracle version is 18.104.22.168.0
after creating capture table and subscribing
I am following the process of
as subscriber: (for each table)
select from CDCview
as publisher: (after all tables processed)
It seems to eventually purge the capture tables, but I recently added a rather high traffic table to the list and would like it to purge more often than it seems to do by default.
There is only one publisher and one subscriber
It was my understanding that this is not how it is supposed to work.
