[SyncDbService] Section

The [SyncDbService] section, which enables you to configure SDS, can contain the parameters summarized in the following table.

Parameter	Default	Description
AuditCauseEvents	False	Specifies whether non-immediate user events caused on persistent objects are audited in the transaction journal for replay on secondary databases.
ConnectionPollInterval	30	Defines in seconds the interval at which the secondary database polls the primary database to determine reachability via the communication paths. (Configured on secondary databases.)
DatabaseRole	Not specified	Activates SDS on a database server node and determines the starting database role for the server.
DatabaseSubrole	Not specified	Activates the SDS secondary as an RPS node.
JournalReadBuffers	4	Specifies the number of buffers to use when reading a journal file on disk.
JournalReplayBlocksize	128K bytes	Specifies the size in bytes of each read buffer used when replaying a journal file.
JournalXferBlocksize	128K bytes	Specifies the size in bytes used for journal file disk and network I/O operations.
JournalXferCompression	True	When enabled, causes SDS to compress journal data blocks for transmission across the network.
MaxDeferredTransactions	30	Pauses transaction replay until the backlog of deferred transactions has reduced to zero (0).
MaxSecondaries	16	Specifies the maximum number of secondary databases that can attach to a primary database server.
MyName	Not specified	Specifies a unique name for a JADE system operating within a Synchronized Database Service environment (SDE).
PrimaryServerName	Not specified	Specifies the name on the secondary database server of the JADE system with the primary role.
ReadAccessDisabled	False	Specifies whether read access to the database is disabled.
ReconnectInterval	300 seconds	Specifies the frequency at which a secondary database server attempts to reconnect to its primary server when a primary server is not available.
SyncMode	JournalBlockWrite	Specifies the mode in which journals are transferred to secondary databases from the primary database. The default JournalBlockWrite value transfers blocks as they are generated. Set the value to JournalSwitch if you want to transfer journal data when the journal is complete.
TrackingDisabled	False	Specifies whether the database tracking (journal replay) process is disabled.
