takes effect
After you edit your onconfig file and restart the database server.
When you reset the value dynamically in your onconfig file by running the onmode -wf command.

By default, replication servers flush logs after 50 replicated transactions are applied, or after 5 seconds, whichever happens first.

If a replication server is a primary server for shared-disk secondary servers, you might want to reduce the replication latency. Set the CDR_MAX_FLUSH_SIZE configuration parameter to 1 to flush the logs after each replicated transaction.
