AdministeringIn addition to administering the database server, you can tune performance, replicate data, and archive data.
Enterprise ReplicationThe HCL OneDB™ Enterprise Replication Guide describes the concepts of data replication using HCL® OneDB® Enterprise Replication, including how to design your replication system, as well as administer and manage data replication throughout your enterprise.

Enterprise Replication configuration parameter and environment variable referenceYou can use configuration parameters and environment variables to configure the behavior of Enterprise Replication.
CDR_MAX_FLUSH_SIZE configuration parameterSpecifies the maximum number of replicated transactions that are applied before the logs are flushed.

CDR_MAX_FLUSH_SIZE configuration parameter

Specifies the maximum number of replicated transactions that are applied before the logs are flushed.

onconfig.std value: CDR_MAX_FLUSH_SIZE 50
default value if not present in the onconfig file: 50
range of values: A positive integer that represents the maximum number of transactions to apply before the logs are flushed.
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.
