JDBC Type 4 Driver 1.1 Programmer's Reference
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.
The driver creates n connections (where n is initialPoolSize) for each connection pool
when the first connetion 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.)
Range: -1 to maxPoolSize
Any negative value is treated as -1.●
Values can be less than minPoolSize, but must not exceed maxPoolSize. If the
specified value is greater than maxPoolSize, the maxPoolSize property value is
used.
●
For example: initialPoolSize=10
ISO88591 Property
The ISO88591 character-set mapping property corresponds to the SQL/MX ISO88591 character
set, which is a single- byte 8-bit character set for character data types. This property supports
English and other Western European languages. For more information, see Internationalization
(I18N) Support.
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.
Data type: String
Default: ISO88591_1
The value can be any valid Java Canonical Name as listed in the "Canonical Name for java.io
and java.lang API" column of the Sun documentation, Supported Encodings
(http://java.sun.com/j2se/1.4.2/docs/guide/intl/encoding.doc.html).
