All implemented interfaces:
- public class Sybase11DataStoreHelper
- extends SybaseDataStoreHelper
Sybase11DataStoreHelper
is a DataStoreHelper
implementation
customized for Sybase 11.9.2.
It allows for plugging in function specific to Sybase 11.9.2.
When mapping a SQLException
, the SQLException
mappings from the
SybaseDataStoreHelper
are searched first, and subsequently, if no match is
found, the SQLException
mappings from the GenericDataStoreHelper
are searched.
If you have additional requirements on Sybase 11.9.2, you should consider subclassing this
implementation.
Note: This class and its methods can not be called or referenced directly by user applications.

WAS 5.0.1

Constructor Detail
Sybase11DataStoreHelper
- public Sybase11DataStoreHelper( java.util.Properties props)
Parameters:
props
- DataStoreHelper
properties. Method Detail
getIsolationLevel
- public int getIsolationLevel(AccessIntent aIntent)
- throws javax.resource.ResourceException
This method determines the transaction isolation level based on the specified
AccessIntent
.
If the AccessIntent
parameter is null, a default value should be returned
that is appropriate for the database backend.
For Sybase 11, java.sql.Connection.TRANSACTION_READ_COMMITTED
is
returned in all cases, except when the AccessIntent is
AccessIntent.PESSIMISTIC_UPDATE_LOCK_HINT_EXCLUSIVE
, in which case
java.sql.Connection.TRANSACTION_SERIALIZABLE
is returned.
Specified by:
getIsolationLevel
in interface DataStoreHelper
Overrides:
getIsolationLevel
in class SybaseDataStoreHelper
Parameters:
aIntent
- An AccessIntent
Returns:
A transaction isolation level appropriate for the specified
AccessIntent
. Throws:
javax.resource.ResourceException
- If a transaction isolation level cannot be determined
from the AccessIntent
. See Also:

getLockType
- public int getLockType(AccessIntent intent)
This method returns a lock type constant based on the update hint value of the
specified AccessIntent.
The lock type is used by the persistence manager to determine which locking hints
are used on a SELECT
statement.
Specified by:
getLockType
in interface DataStoreHelper
Overrides:
getLockType
in class GenericDataStoreHelper
Parameters:
intent
- An AccessIntent
Returns:
the lock type constant. Valid values are defined in
com.ibm.websphere.rsadapter.WSInteractionSpec
:
LOCKTYPE_SELECT
LOCKTYPE_SELECT_FOR_UPDATE

Sybase11DataStoreHelper
constructor creates a newSybase11DataStoreHelper
based on theDataStoreHelper
properties provided. All implementations inheriting from a data store helper must supply this same list of properties to their super class by invoking the constructor of their super class with the list of properties.
