GoldenGate does not appear to work with 4k block size redo logs. (Doc ID 2139396.1)

Last updated on JANUARY 25, 2017

Applies to:

Oracle GoldenGate - Version 11.2.1.0.4 and later
Information in this document applies to any platform.

Goal

When we create (begin now) and start the extract, when the database has a 4k redo block, the extract goes into running status, but hangs and shows sequence number is 0 and is on "First Record." A SEND EXTRACT STATUS command hangs (times out), and STOP EXTRACT command hangs too. When we kill the extract, delete it and set the redo block size back to 1k, we can recreate the extract with no issues.
