We could see latency in the logstream task after some change activity at the source side. more redo logs got generated. Now the task is running behind of 100 to 200 logs. How to make replicate to read faster these redo logs.?
And also i could see around 24 transactions are not committed at source.
You need to check whether there is any long running transaction at the Oracle side which is not committed yet.
Replicate will be waiting for the source for the transaction to gets commit so latency will increase. Once transactions get committed, it will transfer the data to the target accordingly.
