Name

The name of this configuration. WebLogic Server uses an MBean to implement and persist the configuration.

MBean: weblogic.management.
configuration.
JDBCDataSourceMBean

Attribute: Name

Configurable: yes

Readable: yes

Writable: yes

JNDI Name

The JNDI path to where this DataSource is bound.

Applications that look up the JNDI path will get a javax.sql.DataSourceinstance that corresponds to this DataSource.

MBean: weblogic.management.
configuration.
JDBCDataSourceMBean

Attribute: JNDIName

Configurable: yes

Readable: yes

Writable: yes

Pool Name

The name of the connection pool with which the DataSource is associated.

Calls from applications to getConnection()on this DataSource will return a connection from the associated connection pool.

MBean: weblogic.management.
configuration.
JDBCDataSourceMBean

Attribute: PoolName

Configurable: yes

Readable: yes

Writable: yes

Row Prefetch Enabled

Controls row prefetching between a client and WebLogic Server for each ResultSet. When an external client accesses a database using JDBC through Weblogic Server, row prefetching improves performance by fetching multiple rows from the server to the client in one server access. WebLogic Server will ignore this setting and not use row prefetching when the client and WebLogic Server are in the same JVM.

MBean: weblogic.management.
configuration.
JDBCDataSourceMBean

Attribute: RowPrefetchEnabled

Default: false

Readable: yes

Writable: yes

Row Prefetch Size

The number of result set rows to prefetch for a client. The optimal value depends on the particulars of the query. In general, increasing this number will increase performance, until a particular value is reached. At that point further increases do not result in any significant performance increase. Very rarely will increased performance result from exceeding 100 rows. The default value should be reasonable for most situations.

MBean: weblogic.management.
configuration.
JDBCDataSourceMBean

Attribute: RowPrefetchSize

Minimum: 2

Maximum: 65536

Default: 48

Configurable: yes

Readable: yes

Writable: yes

Stream Chunk Size

Data chunk size for steaming datatypes. Streaming datatypes (for example resulting from a call to getBinaryStream()) will be pulled in StreamChunkSize sized chunks from WebLogic Server to the client as needed.

MBean: weblogic.management.
configuration.
JDBCDataSourceMBean

Attribute: StreamChunkSize

Units: bytes

Minimum: 1

Maximum: 65536

Default: 256

Configurable: yes

Readable: yes

Writable: yes
