Data source minimum required settings for Microsoft SQL Server

These properties vary according to the database vendor requirements for Java™ Database Connectivity (JDBC) driver implementations. You must set the appropriate properties on every data source that you configure. These settings are for Microsoft SQL Server data sources.

The application server also supports two options for setting isolation level in Microsoft SQL Server: SNAPSHOT and READ_COMMITTED_SNAPSHOT.
Table 1. Isolation levels in Microsoft SQL Server . The following table describes these isolation levels and configuration considerations.
JDBC provider Microsoft SQL Server feature Configuration consideration
Microsoft SQL Server JDBC Driver SNAPSHOT isolation level Set the isolation level constant by invoking the setTransactionIsolation method with one of the following attributes:
  • conn.setTransactionIsolation (com.microsoft.sqlserver.jdbc. SQLServerConnection. TRANSACTION_SNAPSHOT)
  • conn.setTransactionIsolation(value_of_constant)
READ_COMMITTED_SNAPSHOT isolation level This isolation level is an implementation of the Read committed isolation level. The policy enforces optimistic locking for read operations with Microsoft SQL Server.
  1. Configure the isolation level on the database.
  2. Invoke the setTransactionIsolation method with the conn.setTransactionIsolation (java.sql.Connection. TRANSACTION_READ_COMMITTED) attribute.
DataDirect ConnectJDBC type 4 driver for Microsoft SQL Server SNAPSHOT isolation level This isolation level implements optimistic locking for transactions in which Microsoft SQL Server serializes the data.
Configure the ALLOW_SNAPSHOT_ISOLATION setting on the database, and then set the isolation level in one of two ways:
  • By isolation level constant. Invoke the setTransactionIsolation method with one of the following attributes:
    • conn.setTransactionIsolation (com.ddtek.jdbc.extensions. ExtConstants.TRANSACTION_SNAPSHOT)
    • conn.setTransactionIsolation(16)
  • By the custom data source property:
    • Set the data source custom property snapshotSerializable to true.
    • Invoke the setTransactionIsolation method with the conn.setTransactionIsolation (java.sql.Connection. TRANSACTION_SERIALIZABLE) attribute:
READ_COMMITTED_SNAPSHOT isolation level This isolation level is an implementation of the Read committed isolation level. The policy enforces optimistic locking for read operations with Microsoft SQL Server.
  1. Configure the isolation level on the database.
  2. Invoke the setTransactionIsolation method with the conn.setTransactionIsolation (java.sql.Connection. TRANSACTION_READ_COMMITTED) attribute.

You can configure the following types of providers:
  • Microsoft SQL Server JDBC Driver
    The Microsoft SQL Server JDBC driver supports this data source:
    com.microsoft.sqlserver.jdbc.SQLServerConnectionPoolDataSource
    The JDBC provider requires the following Java archive (JAR) files: 
    sqljdbc4.jar
    The JDBC provider requires the following DataStoreHelper class: 
    com.ibm.websphere.rsadapter.MicrosoftSQLServerDataStoreHelper
    The JDBC provider requires a valid authentication alias.
    The JDBC driver requires the following properties:
    serverName
    Specifies the name of the server in which Microsoft SQL Server resides. Example: myserver.mydomain.com
    portNumber
    Specifies the TCP/IP port that Microsoft SQL Server uses for communication. Port 1433 is the default.
    databaseName
    Specifies the name of the database from which the data source obtains connections. Example: Sample.
  • Microsoft SQL Server JDBC Driver (XA)
