Neoview JDBC Type 4 Driver Programmer's Reference (R2.2, R2.3, R2.4, R2.5)

Set this property on the DataSource object. For information about how to set the property
value, see “How to Specify JDBC Type 4 Properties” (page 38).
Data type: String
Default: none
For example: dataSourceName=myDataSource
description Property
The description property specifies the registered source name.
Set this property on a DataSource object, ConnectionPoolDataSource object, or
DriverManager object. For information about how to set properties, see “How to Specify JDBC
Type 4 Properties” (page 38).
Data type: String
Default: none
The value can be any valid identifier.
fetchBufferSize Property
The fetchBufferSize property provides the benefits of bulk fetch.
This property sets the value in kilobytes (KB) of the size of the fetch buffer that is used when
rows are fetched from a ResultSet object after a successful executeQuery()operation on a
statement.
Set this property on a DataSource object, ConnectionPoolDataSource object, or
DriverManager object. For information about how to set properties, see “How to Specify JDBC
Type 4 Properties” (page 38).
Data type: short
Default size: 4
Range: 4 through 32767
• Zero and negative values are treated as default values.
• The Type 4 driver guarantees that the number of rows internally fetched will be no less than
the minimum of the row size (set using thesetFetchSize method) and the number of
rows that will fit in the memory specified by the setFetchSize (set using the property).
For example: fetchBufferSize=32
initialPoolSize Property
The initialPoolSize property sets the initial connection pool size when connection pooling
is used with the Type 4 driver.
Set this property on a DataSource object or DriverManager object. This property is ignored
for connections made through the ConnectionPoolDataSource object, For information about
how to set the property value, see “How to Specify JDBC Type 4 Properties” (page 38).
The driver creates n connections (where n is initialPoolSize) for each connection pool when
the first connection is requested. For example, if initialPoolSize is set to 5 for a data source,
the driver attempts to create and pool five connections the first time the application calls the data
source’s getConnection() method.
Data type: int
Units: number of physical connections
Default: -1 (Do not create an initial connection pool.)
