Basic Tab

The following table and the sections below lists and explains the connection properties that are in the Basic Tab of the New Data Source Window.

Datasource Name	The name of the Datasource.
Host	Name of the host machine or the host machine’s IP address.
Port	The Port number.
DBMS Type	DataDirect SQL access keyword that specifies the means by which the adapter accesses the data. Most of the storage schemes listed below do not allow or are not optimized for SQL push. To use more than one DBMS type, create more data source connections in Studio. Supported DBMS type values are: • ADABAS—A very fast transaction processing mainframe database. • DATA—May be used to access both VSAM and sequential files. • DB2—Provides the broadest coverage of SQL-99 functionality, and the most efficient SQL push to the DataDirect Mainframe. Requires a database name. • IMSDB—Provides access to multi-dimensional databases. Appearance of query results differs from conventional relational database results. • VSAM—A read-only storage system. • VSAM/CICS—Transaction processing data system for on-line and batch systems that allows both read and write access.
Database Name	Name or alias of the underlying data source. TDV Server uses this name to find and connect to the data source.
Plan	Data isolation plan. The default value, SDBC1010, specifies cursor stability. Other values specify repeatable reads, read stability, or uncommitted reads. See the Shadow RTE Client/adapters Installation and Administration Guide for more information.
Login/User, Password	User name and password required to access the data source.
Pass-through Login	Flag to indicate whether pass-through login is enabled or not.
Transaction Isolation	The degree to which transactions are isolated from data modifications made by other transactions.

Datasource Name

The name of the data source.

Data Type

DBMS Type

DataDirect SQL access keyword that specifies the means by which the adapter accesses the data. Most of the storage schemes listed below do not allow or are not optimized for SQL push. To use more than one DBMS type, create more data source connections in Studio.

Supported DBMS type values are:

•

ADABAS—A very fast transaction processing mainframe database.

•

DATA—May be used to access both VSAM and sequential files.

•

DB2—Provides the broadest coverage of SQL-99 functionality, and the most efficient SQL push to the DataDirect Mainframe. Requires a database name.

•

IMSDB—Provides access to multi-dimensional databases. Appearance of query results differs from conventional relational database results.

•

VSAM—A read-only storage system.

•

VSAM/CICS—Transaction processing data system for on-line and batch systems that allows both read and write access.

Data Type

String

Default Value

ADABAS

Remarks

None

Database Name

Name or alias of the underlying data source. TDV Server uses this name to find and connect to the data source.

Data Type

string

Default Value

""

Plan

Data isolation plan. The default value, SDBC1010, specifies cursor stability. Other values specify repeatable reads, read stability, or uncommitted reads. See the Shadow RTE Client/adapters Installation and Administration Guide for more information.

Data Type

String

Default Value

SDBC1010

Remarks

None

Login/User, Password

User name and password required to access the data source.

Data Type

string

Default Value

“”

Remarks

When the data source is used as a target for cache tables or data ship, the user must also have permission to create tables, execute DDL, and perform other required tasks. Refer to the individual data source descriptions for details.

Transaction Isolation

The degree to which transactions are isolated from data modifications made by other transactions.

Data Type

string

Default Value

NONE

Remarks

Valid values are:

•

Read Uncommitted—Dirty reads, nonrepeatable reads, and phantom reads can occur.

•

Read Committed—Nonrepeatable reads and phantom reads can occur.

•

Repeatable Read—Only phantom reads can occur.

•

Serializable—Dirty reads, nonrepeatable reads, and phantom reads are prevented.

•

None

Pass-through Login

Flag to indicate whether pass-through login is enabled or not.

Data Type

string

Default Value

""

Remarks

Disabled (default)—This allows automated provisioning of a connection pool. Open connection threads can be used by authorized users after the validation query verifies connection status. If pass-through login is disabled, the Save Password check box is not available.

Enabled—A new connection to the data source uses the credentials supplied by the client when data is requested from that data source for the first time. Subsequent requests by the same user reuse the existing connection. When another user attempts to connect to a data source, a new connection is created.

See “Managing Security for TDV Resources” in the TDV Administration Guide for details.
