SQL Data Service Properties

SQL Data Service Properties

SQL data service properties include read-only general properties and properties to configure the settings the Data Integration Service uses when it runs the SQL data service.
When you expand an SQL data service in the top panel of the Applications view, you can access the following objects contained in an SQL data service:
  • Virtual tables
  • Virtual columns
  • Virtual stored procedures
The Applications view displays read-only general properties for SQL data services and the objects contained in the SQL data services. Properties that appear in the view depend on the object type.
The following table describes the read-only general properties for SQL data services, virtual tables, virtual columns, and virtual stored procedures:
Property
Description
Name
Name of the selected object. Appears for all object types.
Description
Short description of the selected object. Appears for all object types.
Type
Type of the selected object. Appears for all object types.
Location
The location of the selected object. This includes the domain and Data Integration Service name. Appears for all object types.
JDBC URL
JDBC connection string used to access the SQL data service. The SQL data service contains virtual tables that you can query. It also contains virtual stored procedures that you can run. Appears for SQL data services.
Column Type
Datatype of the virtual column. Appears for virtual columns.
The following table describes the configurable SQL data service properties:
Property
Description
Startup Type
Determines whether the SQL data service is enabled to run when the application starts or when you start the SQL data service. Enter ENABLED to allow the SQL data service to run. Enter DISABLED to prevent the SQL data service from running.
Trace Level
Level of error written to the log files. Choose one of the following message levels:
  • OFF
  • SEVERE
  • WARNING
  • INFO
  • FINE
  • FINEST
  • ALL
Default is INFO.
Connection Timeout
Maximum number of milliseconds to wait for a connection to the SQL data service. Default is 3,600,000.
Request Timeout
Maximum number of milliseconds for an SQL request to wait for an SQL data service response. Default is 3,600,000.
Sort Order
Sort order that the Data Integration Service uses for sorting and comparing data when running in Unicode mode. You can choose the sort order based on your code page. When the Data Integration runs in ASCII mode, it ignores the sort order value and uses a binary sort order. Default is binary.
Maximum Active Connections
Maximum number of active connections to the SQL data service.
Result Set Cache Expiration Period
The number of milliseconds that the result set cache is available for use. If set to -1, the cache never expires. If set to 0, result set caching is disabled. Changes to the expiration period do not apply to existing caches. If you want all caches to use the same expiration period, purge the result set cache after you change the expiration period. Default is 0.
DTM Keep Alive Time
Number of milliseconds that the DTM instance stays open after it completes the last request. Identical SQL queries can reuse the open instance. Use the keep alive time to increase performance when the time required to process the SQL query is small compared to the initialization time for the DTM instance. If the query fails, the DTM instance terminates.
Must be an integer. A negative integer value means that the DTM Keep Alive Time for the Data Integration Service is used. 0 means that the Data Integration Service does not keep the DTM instance in memory. Default is -1.
Optimization Level
The optimizer level that the Data Integration Service applies to the object. Enter the numeric value that is associated with the optimizer level that you want to configure. You can enter one of the following numeric values:
  • 0. The Data Integration Service does not apply optimization.
  • 1. The Data Integration Service applies the early projection optimization method.
  • 2. The Data Integration Service applies the early projection, early selection, push-into, and predicate optimization methods.
  • 3. The Data Integration Service applies the cost-based, early projection, early selection, push-into, predicate, and semi-join optimization methods.
