|
Port
|
Port number for the data source to connect with the host.
The Port number for Oracle is 1521.
|
|
Net Service Name
|
This property is available for an Oracle data source with OCI driver.
The TNS name that is set up through Oracle Net Configuration Assistant.
|
|
Pass-through Login
|
To use Kerberos tokens, Oracle data sources must enable pass-through login. In addition, an enabled Kerberos security module must be running on TDV so that Kerberos-authenticated users with session tokens can use it when submitting queries.
|
|
Service Name
|
Name of the database service.
|
|
Ticket Cache
|
Specify the location of where your ticket cache is stored in this field when using Kerberos authentication. Leave the Login and Password fields blank when using ticket cache
Note: Credential cache must be generated with a forwardable option set. To do this, KRB5.INI or KRB5.CONF in the client machine needs to have the parameter libdefaults: forwardable set to true.
|
|
Enable Oracle Database Link
|
Check to improve performance if you plan to use this data source for data caching or data ship optimization. Also add one or more Oracle database links. See the User Guide chapters Configuration Native Caching for Oracle and Data Ship Performance Optimization.
|
|
Enable Pass-Through Prepared Statements
|
For pass-through to work, the prepared statement must call data from only one Oracle database instance. Prepared statements can use data from multiple tables within a single Oracle database instance.
|
|
Include Invalid Introspection Objects
|
Check to return all objects during introspection, including invalid objects.
|
|
Introspect Procedures
|
Checked by default. Ignoring procedures speeds up the initial introspection when only tables are wanted.
|
|
Introspect comments
|
During the introspection process, TDV can retrieve table and column level comments and add them to the annotations field for each resource. See the User Guide Chapter Introspecting Data Source Table and Column Comment Metadata.
|
|
Introspect Using DBA_* Views
|
Oracle maintains multiple metadata views. By default, TDV introspection uses ALL_* views, which list resources for which the user has access to both data and metadata. DBA_* views show all resources in the database regardless of data access permissions. Refer to Oracle documentation for differences and privileges.
|
|
Use pass-through user’s certificate for encryption
|
When pass-through login is configured for use with an Oracle data source, check this box to include the user’s certificate in the SSL negotiation (handshake).
|
|
Is dataship source
|
Indicates whether the physical data source might be used as a source of shipped tables to another data ship enabled data source
|
|
Lower bound/Upper bound
|
TDV uses Explain Plan to arrive at a numeric estimate of the cost of shipping data from a node to the Data Virtualizer. When the cost of shipping a federated query node falls between the limits of the Lowerbound and Upperbound, it is considered eligible for shipment so that it can be processed locally.
|
|
Is dataship target
|
Indicates whether the physical data source might be used to receive shipped tables from another data ship enabled data source.
|
|
Lower bound/Upper bound
|
TDV uses Explain Plan to arrive at a numeric estimate of the cost of shipping data from a node to the Data Virtualizer. When the cost of shipping a federated query node falls between the limits of the Lowerbound and Upperbound, it is considered eligible for shipment so that it can be processed locally.
|
|
Schema path for Temp Tables
|
A relative path to set the location of the temp tables on the data source. It is the name of a schema in the data source.
|
|
Temp Table Prefix
|
A character string addition to temporary table names so that they are recognized if they are needed.
|
|
Database Link List
|
Add your database links separated with semicolons, using the following syntax: [DBLINK NAME]@[DBLINK OWNER DS PATH]
For example: oral2_dblink@/users/composite/test/sources/dship/DEV-DSJ-ORA11G-2
