The mine process reads the Oracle online redo logs at the source database in real time. The mine process converts information from the Oracle redo log into a Dbvisit Replicate internal format called a PLOG (parsed log). When the information required is no longer in the redo logs, Dbvisit Replicate will automatically switch to the archive logs and switch back to the redo logs when it has caught up. Redo and archive logs using filesystem and ASM are supported. There can be more than one Mine process. Each Mine process will have a unique name which is determined by the user. Example: MINE, MINE2, etc. |
