Application Programming Guide and Reference for Java
With progressive streaming, also known as dynamic data format, the data
source dynamically determines the most efficient mode in which to return LOB
or XML data, based on the size of the LOBs or XML objects. The value of the
streamBufferSize parameter determines whether the data is materialized when
it is returned.
The data type of progressiveStreaming is int. Valid values are
DB2BaseDataSource.YES (1) and DB2BaseDataSource.NO (2). If the
progressiveStreaming property is not specified, the progressiveStreaming value
is DB2BaseDataSource.NOT_SET (0).
If the connection is to a data source that supports progressive streaming, and
the value of progressiveStreaming is DB2BaseDataSource.YES or
DB2BaseDataSource.NOT_SET, the JDBC driver uses progressive streaming to
return LOBs and XML data.
If the value of progressiveStreaming is DB2BaseDataSource.NO, or the data
source does not support progressive streaming, the way in which the JDBC
driver returns LOB or XML data depends on the value of the
fullyMaterializeLobData property.
resultSetHoldability
Specifies whether cursors remain open after a commit operation. The data type
of this property is int. Valid values are:
DB2BaseDataSource.HOLD_CURSORS_OVER_COMMIT (1)
Leave cursors open after a commit operation.
DB2BaseDataSource.CLOSE_CURSORS_AT_COMMIT (2)
Close cursors after a commit operation.
DB2BaseDataSource.NOT_SET (0)
Close cursors after a commit operation. This is the default value.
retryIntervalForClientReroute
For automatic client reroute, specifies the amount of time in seconds between
connection retries.
The data type of this property is int.
The IBM Data Server Driver for JDBC and SQLJ uses the
retryIntervalForClientReroute property only if the maxRetriesForClientReroute
property is also set.
If maxRetriesForClientReroute or retryIntervalForClientReroute is not set, the
IBM Data Server Driver for JDBC and SQLJ performs retries for 10 minutes.
If the enableClientAffinitiesList is set to DB2BaseDataSource.NO (2), an attempt
to connect to the primary server and alternate servers counts as one retry. The
driver waits the number of seconds that is specified by
retryIntervalForClientReroute before retrying the connection. If
enableClientAffinitiesList is set to DB2BaseDataSource.YES (1), each server that
is specified by the clientRerouteAlternateServerName and
clientRerouteAlternatePortNumber values is retried after the number of
seconds that is specified by retryIntervalForClientReroute.
The default value for retryIntervalForClientReroute is 0.
securityMechanism
Specifies the DRDA security mechanism. The data type of this property is int.
Possible values are:
