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_APPLY Configuration ParameterSpecifies the minimum and maximum number of data sync threads. The value is updated dynamically as needed.

CDR_APPLY Configuration Parameter

Specifies the minimum and maximum number of data sync threads. The value is updated dynamically as needed.

onconfig.std value: Not in the onconfig.std file.
range of values: Two positive integers that are separated by a comma and that represent the minimum and maximum number of threads per CPU virtual processor. If only one value is specified, that value is the maximum and the minimum is set to 1.

If you do not set the CDR_APPLY configuration parameter explicitly, Enterprise Replication automatically allocates data sync threads for each CPU VP based on need:

The minimum number of data sync threads is the number of available CPU VPs.
The maximum number of data sync threads is four times the number of available CPU VPs.

You can set the CDR_APPLY configuration parameter to control the minimum and maximum configurable data sync apply threads irrespective of the CPU VP configuration.
