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.
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:
|
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.
|
|
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:
|
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.
