I want to analyze the journal, but the journal seen in terminal seems to be incomplete.

So how to transform journal into complete plain text.

My installation package is C2010_1_6_952_0_11445_x64.exe.
 

After enabling archiving log functions, Oracle can get real-time change data through CDC.

Can Cache database realize such functions?

My requirement is to take incremental data from the cache database regularly every day and synchronize it to other relational databases.

Incremental data can be text files.
