Advanced replication system parameter categories

Advanced Replication Guide : Bulletin board parameters : Advanced replication system parameter categories

Advanced replication system parameters are divided into the following categories:

Read-only system parameters

Read-only system parameters are maintained by solidDB^® and can be read only by using the following syntax:

GET_PARAM(parameter_name)

The lifecycle of parameters in this category is one transaction, that is, values of these parameters is always initialized at the beginning of the transaction.

Updateable transaction-level system parameters

Users can set and update transaction-level system parameters using the following function call inside the transaction:

PUT_PARAM(parameter_name, value)

Updateable system parameters are used by solidDB^® advanced replication to configure synchronization-related operations.

The lifecycle of parameters in this category is one transaction, that is, values of these parameters is always initialized at the beginning of the transaction.

Database catalog level system parameters

Database catalog level system parameters are set by using the following syntax:

SET SYNC PARAMETER(parameter_name value)

Parameters in this category are database catalog level parameters that are valid until changed or removed. They are specified as bulletin board parameters.

Full syntax and examples of usage of GET_PARAM(), PUT_PARAM() and SET SYNC PARAMETER functions are described in solidDB^® SQL Guide.
