Class AS400JDBCDataSource
java.lang.Object
com.ibm.as400.access.AS400JDBCDataSource
- All Implemented Interfaces:
- Serializable, Cloneable, Wrapper, Referenceable, CommonDataSource, DataSource
- Direct Known Subclasses:
- AS400JDBCConnectionPoolDataSource, AS400JDBCXADataSource
public class AS400JDBCDataSource
- extends Object
- implements DataSource, Referenceable, Serializable, Cloneable
The AS400JDBCDataSource class represents a factory for IBM i database connections.
The following is an example that creates an AS400JDBCDataSource object and creates a
connection to the database.
// Create a data source for making the connection.
AS400JDBCDataSource datasource = new AS400JDBCDataSource("myAS400");
datasource.setUser("myUser");
datasource.setPassword("MYPWD");
// Create a database connection to the system.
Connection connection = datasource.getConnection();
The following example registers an AS400JDBCDataSource object with JNDI and then
uses the object returned from JNDI to obtain a database connection.
// Create a data source to the IBM i database.
AS400JDBCDataSource dataSource = new AS400JDBCDataSource();
dataSource.setServerName("myAS400");
// Register the datasource with the Java Naming and Directory Interface (JNDI).
Hashtable env = new Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.fscontext.RefFSContextFactory");
Context context = new InitialContext(env);
context.bind("jdbc/customer", dataSource);
// Return an AS400JDBCDataSource object from JNDI and get a connection.
AS400JDBCDataSource datasource = (AS400JDBCDataSource) context.lookup("jdbc/customer");
Connection connection = datasource.getConnection("myUser", "MYPWD");

This method has no effect on IBM i V6R1 or earlier.
The possible values for this property are
CONCURRENTACCESS_NOT_SET
,
CONCURRENTACCESS_USE_CURRENTLY_COMMITTED
,
CONCURRENTACCESS_WAIT_FOR_OUTCOME
and
CONCURRENTACCESS_SKIP_LOCKS
,
with the property defaulting to CONCURRENTACCESS_NOT_SET
.
Setting this property to default exhibits the default behavior on the servers
i.e., the semantic applied for read
transactions to avoid locks will be determined by the server.
CONCURRENTACCESS_USE_CURRENTLY_COMMITTED
specifies that driver will flow USE CURRENTLY COMMITTED
to server. Whether CURRENTLY COMMITTED will actually be in effect is
ultimately determined by server.
CONCURRENTACCESS_WAIT_FOR_OUTCOME
specifies that driver will flow WAIT FOR OUTCOME
to server. This will disable the CURRENTLY COMMITTED behavior at the server,
if enabled, and the server will wait for the commit or rollback of data in the process of
being updated.
CONCURRENTACCESS_SKIP_LOCKS
specifies that driver will flow SKIP LOCKS
to server. This directs the database manager to skip records in the case of record lock conflicts.
- Returns:
- The concurrent access resolution setting. Possible return valuse:
CONCURRENTACCESS_NOT_SET
,
CONCURRENTACCESS_USE_CURRENTLY_COMMITTED
,

The default value is not to use extended dynamic support.
isExtendedMetaData
public boolean isExtendedMetaData()
- Indicates whether the driver should request extended metadata from the

- true if extended metadata will be requested; false otherwise.
The default value is false.
isExtendedMetadata
public boolean isExtendedMetadata()
- Indicates whether the driver should request extended metadata from the
IBM i system. If this property is set to true, the accuracy of the information
that is returned from ResultSetMetaData methods getColumnLabel(int),

In addition, the ResultSetMetaData method getSchemaName(int) will be supported with this
property set to true. However, performance will be slower with this
property on. Leave this property set to its default (false) unless you
need more specific information from those methods.
For example, without this property turned on, isSearchable(int) will
always return true even though the correct answer may be false because
the driver does not have enough information from the system to make a judgment. Setting
this property to true forces the driver to get the correct data from the IBM i system.
- Returns:
- true if extended metadata will be requested; false otherwise.
The default value is false.
Note: this method is the same as isExtendedMetaData() so that it corresponds to the connection property name
isFullOpen
public boolean isFullOpen()
- Indicates whether the IBM i system fully opens a file when performing a query.
By default the system optimizes opens so they perform better. In
certain cases an optimized open will fail. In some
cases a query will fail when a database performance monitor
is turned on even though the same query works with the monitor
turned off. In this case set the full open property to true.
This disables optimization on the system.
- Returns:
- true if files are fully opened; false otherwise.
The default value is false.

public boolean isSavePasswordWhenSerialized()
- Indicates whether the password is saved locally with the rest of
the properties when this data source object is serialized.
If the password is saved, it is up to the application to protect
the serialized form of the object because it contains all necessary
information to connect to the IBM i system. The default is false. It
is a security risk to save the password with the rest of the
properties so by default the password is not saved. If the programmer
chooses to accept this risk, call setSavePasswordWhenSerialized(true)
to force the Toolbox to save the password with the other properties
when the data source object is serialized.
- Returns:
- true if the password is saved with the rest of the properties when the
data source object is serialized; false otherwise.
The default value is false.

public boolean isTranslateBoolean()
- Indicates how Boolean objects are interpreted when setting the value
for a character field/parameter using the PreparedStatement.setObject(),
CallableStatement.setObject() or ResultSet.updateObject() methods. Setting the
property to "true", would store the Boolean object in the character field as either
"true" or "false". Setting the property to "false", would store the Boolean object
in the character field as either "1" or "0".
- Returns:
- true if boolean data is translated; false otherwise.

- The driver behaviors to override.
Valid values include:
- 1 - Do not throw an exception if Statement.executeQuery() or
PreparedStatement.executeQuery() do not return a result set.
Instead, return null for the result set.
Carefully consider the result of overriding the default behavior of the
driver. For example, setting the value of this property to 1 means
the driver will no longer throw an exception even though the JDBC 3.0
specification states throwing an exception is the correct behavior.
Be sure your application correctly handles the altered behavior.

setBlockCriteria
public void setBlockCriteria(int blockCriteria)
- Sets the criteria for retrieving data from the IBM i system in
blocks of records. Specifying a non-zero value for this property
will reduce the frequency of communication to the system, and
therefore increase performance.
- Parameters:

- The block criteria.
Valid values include:
- 0 (no record blocking)
- 1 (block if FOR FETCH ONLY is specified)
- 2 (block if FOR UPDATE is specified) - The default value.
setBlockSize
public void setBlockSize(int blockSize)
- Sets the block size in kilobytes to retrieve from the IBM i system and
cache on the client. This property has no effect unless the block criteria
property is non-zero. Larger block sizes reduce the frequency of
communication to the system, and therefore may increase performance.
- Parameters:
blockSize
- The block size in kilobytes.
Valid values include:
- 0
- 8
- 16
- 32 - The default value.
- 64
- 128
- 256

setConcurrentAccessResolution
public void setConcurrentAccessResolution(int concurrentAccessResolution)
- This method sets concurrent access resolution. This method overrides the setting of ConcurrentAccessResolution on the datasource or connection
URL properties. This method has no effect on
IBM i V6R1 or earlier.
The possible values for this property are
CONCURRENTACCESS_NOT_SET
,
CONCURRENTACCESS_USE_CURRENTLY_COMMITTED
,
CONCURRENTACCESS_WAIT_FOR_OUTCOME
and
CONCURRENTACCESS_SKIP_LOCKS
,
with the property defaulting to CONCURRENTACCESS_NOT_SET
.
Setting this property to default exhibits the default behavior on the servers
i.e., the semantic applied for read
transactions to avoid locks will be determined by the server.
CONCURRENTACCESS_USE_CURRENTLY_COMMITTED
specifies that driver will flow USE CURRENTLY COMMITTED
to server. Whether CURRENTLY COMMITTED will actually be in effect is
ultimately determined by server.
CONCURRENTACCESS_WAIT_FOR_OUTCOME
specifies that driver will flow WAIT FOR OUTCOME
to server. This will disable the CURRENTLY COMMITTED behavior at the server,
if enabled, and the server will wait for the commit or rollback of data in the process of
being updated.
CONCURRENTACCESS_SKIP_LOCKS
specifies that driver will flow SKIP LOCKS
to server. This directs the database manager to skip records in the case of record lock conflicts.
- Parameters:
concurrentAccessResolution
- The current access resolution setting. Possible valuse:
CONCURRENTACCESS_NOT_SET
,
CONCURRENTACCESS_USE_CURRENTLY_COMMITTED
,
CONCURRENTACCESS_WAIT_FOR_OUTCOME
, or
CONCURRENTACCESS_SKIP_LOCKS
setCursorSensitivity
public void setCursorSensitivity(String cursorSensitivity)
- Sets the cursor sensitivity to be requested from the database. If the resultSetType is

The following criteria are used to determine
which database is accessed:
- If a database name is specified, that database is used. Attempts
to connect will fail if the database does not exist.
- If special value *SYSBAS is specified, the system default database is used.
- If a database name is not specified, the database specified
in the job description for the user profile is used.

- Parameters:
errors
- The error message level.
Valid values include: "basic" and "full". The default value is "basic".
setExtendedDynamic
public void setExtendedDynamic(boolean extendedDynamic)
- Sets whether to use extended dynamic support. Extended dynamic
support provides a mechanism for caching dynamic SQL statements on
the IBM i system. The first time a particular SQL statement is prepared, it is
stored in an SQL package on the system.
If the package does not exist, it will be automatically created.
On subsequent prepares of the
same SQL statement, the system can skip a significant part of the
processing by using information stored in the SQL package. If this
is set to "true", then a package name must be set using the "package"
property.

- If extended dynamic support is used; false otherwise.
The default value is not to use extended dynamic support.
setExtendedMetaData
public void setExtendedMetaData(boolean extendedMetaData)
- Sets whether the driver should request extended metadata from the
IBM i system. This property is ignored when connecting to systems
running OS/400 V5R1 and earlier.
If this property is set to true and connecting to a system running
OS/400 V5R2 or IBM i, the accuracy of the information
that is returned from ResultSetMetaData methods getColumnLabel(int),
isReadOnly(int), isSearchable(int), and isWriteable(int) will be increased.
In addition, the ResultSetMetaData method getSchemaName(int) will be supported with this
property set to true. However, performance will be slower with this
property on. Leave this property set to its default (false) unless you
need more specific information from those methods.
For example, without this property turned on, isSearchable(int) will
always return true even though the correct answer may be false because
the driver does not have enough information from the system to make a judgment. Setting
this property to true forces the driver to get the correct data from the system.
- Parameters:
extendedMetaData
- True to request extended metadata from the system, false otherwise.
The default value is false.
setExtendedMetadata
public void setExtendedMetadata(boolean extendedMetaData)
- Sets whether the driver should request extended metadata from the
IBM i system. This property is ignored when connecting to systems
running OS/400 V5R1 and earlier.
If this property is set to true and connecting to a system running
OS/400 V5R2 or IBM i, the accuracy of the information
that is returned from ResultSetMetaData methods getColumnLabel(int),
isReadOnly(int), isSearchable(int), and isWriteable(int) will be increased.
In addition, the ResultSetMetaData method getSchemaName(int) will be supported with this
property set to true. However, performance will be slower with this
property on. Leave this property set to its default (false) unless you
need more specific information from those methods.
For example, without this property turned on, isSearchable(int) will
always return true even though the correct answer may be false because
the driver does not have enough information from the system to make a judgment. Setting
this property to true forces the driver to get the correct data from the system.
- Parameters:
extendedMetaData
- True to request extended metadata from the system, false otherwise.
The default value is false.
Note: this method is the same as setExtendedMetaData() so that it corresponds to the connection property name
setFullOpen
public void setFullOpen(boolean fullOpen)
- Sets whether to fully open a file when performing a query.
By default the IBM i system optimizes opens so they perform better.
In most cases optimization functions correctly and improves
performance. Running a query repeatedly
when a database performance monitor is turned on may fail
because of the optimization, however.
Leave this property set to its default (false) until
you experience errors running queries with monitors
turned on. At that time set the property to true which
will disable the optimization.
- Parameters:
fullOpen
- True to fully open a file (turn off optimizations), false
to allow optimizations. The default value is false.

- Sets the libraries to add to the server job's library list.
The libraries are delimited by commas or spaces, and
"*LIBL" may be used as a place holder for the server job's
current library list. The library list is used for resolving
unqualified stored procedure calls and finding schemas in
DatabaseMetaData catalog methods. If "*LIBL" is not specified,
the specified libraries will replace the server job's
current library list.
- Parameters:
libraries
- The library list.
setLobThreshold
public void setLobThreshold(int threshold)
- Sets the maximum LOB (large object) size in bytes that
can be retrieved as part of a result set. LOBs that are larger
than this threshold will be retrieved in pieces using extra
communication to the IBM i system. Larger LOB thresholds will reduce
the frequency of communication to the system, but will download
more LOB data, even if it is not used. Smaller LOB thresholds may
increase frequency of communication to the system, but will only
download LOB data as it is needed.

the client connects to the IBM i system, and ends when the connection
is disconnected. Tracing must be started before connecting to
the system since the client enables tracing only at connect time.
Trace data is collected in spooled files on the system. Multiple
levels of tracing can be turned on in combination by adding
the constants and passing that sum on the set method. For example,

setSavePasswordWhenSerialized
public void setSavePasswordWhenSerialized(boolean savePassword)
- Sets whether to save the password locally with the rest of the properties when
this data source object is serialized.
If the password is saved, it is up to the application to protect
the serialized form of the object because it contains all necessary
information to connect to the IBM i system. The default is false. It
is a security risk to save the password with the rest of the
properties so by default the password is not saved. If the application
programmer chooses to accept this risk, set this property to true
to force the Toolbox to save the password with the other properties
when the data source object is serialized.

isWrapperFor
public boolean isWrapperFor(Class<?> iface)
throws SQLException
- Returns true if this either implements the interface argument or is
directly or indirectly a wrapper for an object that does. Returns false
otherwise. If this implements the interface then return true, else if
this is a wrapper then return the result of recursively calling
isWrapperFor
on the wrapped object. If this does not
implement the interface and is not a wrapper, return false. This method
should be implemented as a low-cost operation compared to
unwrap
so that callers can use this method to avoid
expensive unwrap
calls that may fail. If this method
returns true then calling unwrap
with the same argument
should succeed.
- Specified by:
isWrapperFor
in interface Wrapper
- Parameters:
iface
- a Class defining an interface.
- Returns:
- true if this implements the interface or directly or indirectly
wraps an object that does.
- Throws:
SQLException
- if an error occurs while determining whether this is a
wrapper for an object with the given interface.
unwrap
public <T> T unwrap(Class<T> iface)
throws SQLException
- Returns an object that implements the given interface to allow access to
non-standard methods, or standard methods not exposed by the proxy.
If the receiver implements the interface then the result is the receiver
or a proxy for the receiver. If the receiver is a wrapper and the wrapped
object implements the interface then the result is the wrapped object or
a proxy for the wrapped object. Otherwise return the the result of
calling
unwrap
recursively on the wrapped object or a
proxy for that result. If the receiver is not a wrapper and does not
implement the interface, then an SQLException
is thrown.
- Specified by:
unwrap
in interface Wrapper
- Parameters:
iface
- A Class defining an interface that the result must implement.
- Returns:
- an object that implements the interface. May be a proxy for the
actual implementing object.
- Throws:
SQLException
- If no object found that implements the interface
