public class SybaseProxyDSDataStoreHelper
SybaseProxyDSDataStoreHelper
is a DataStoreHelper
implementation customized for using proxy datasource with Sybase databases.
When users use the proxy datasource to connect to Sybase datasources,
this DataStore Helper has to be used.

public boolean doConnectionCleanup(java.sql.Connection conn) throws java.sql.SQLException
This method is used to clean up a connection before it is returned to the connection
pool for later reuse. WebSphere automatically resets all standard connection
properties (fields for which getters and setters are defined on
java.sql.Connection
).
This method may be used to reset other properties proprietary to a specific
JDBC driver/database and do whatever else is necessary to prepare the connection for
reuse.
A DataStoreHelper
is permitted to use the provided connection to create
and execute statements for the purpose of cleaning up the connection. Any statements
created within the doConnectionCleanup
method must be explicitly closed
within the doConnectionCleanup
method. The
doConnectionCleanup
method must never close the
connection being cleaned up.
If any standard connection properties are modified in this method, a value of true must be returned, indicating to WebSphere that at least one standard connection property was modified. A value of false is returned only if no standard connection properties were modified.
GenericDataStoreHelper
does not perform any connection cleanup.
