Disk, memory, and process management
Data storageThe database server uses physical units of storage to allocate disk space. It stores data in logical units. Unlike the logical units of storage whose size fluctuates, each of the physical units has a fixed or assigned size that is determined by the disk architecture.
SbspacesAn sbspace is a logical storage unit composed of one or more chunks that store smart large objects.
Sbspaces and Enterprise ReplicationBefore you define a replication server for , you must create an sbspace. spools the replicated data to smart large objects.

Sbspaces and Enterprise Replication

Before you define a replication server for , you must create an sbspace. spools the replicated data to smart large objects.

Specify the sbspace name in the CDR_QDATA_SBSPACE configuration parameter. uses the default log mode with which the sbspace was created for spooling the row data. The CDR_QDATA_SBSPACE configuration parameter accepts multiple sbspaces, up to a maximum of 32 sbspaces. can support a combination of logging and non-logging sbspaces for storing spooled row data. For more information, see the .

You can have automatically configure disk space from the storage pool and set the appropriate configuration parameters when defining a replication server. If the CDR_QDATA_SBSPACE or the CDR_DBSPACE configuration parameter is not set or is set to blank, the cdr define server command automatically creates the necessary disk space and sets the configuration parameters to appropriate values.
