Connection Attributes for Netezza JDBC

In order to connect to a Netezza data source, the adapter requires connection and authentication information.

You supply this information using the SET CONNECTION_ATTRIBUTES command. You can:

Enter connection and authentication information in the Web Console or the Data Management Console configuration panes. The consoles add the command to the profile you select: the global server profile (edasprof.prf), a user profile (user.prf), or a group profile (if supported on your platform).
Manually add the command in the global server profile (edasprof.prf), in a user profile (user.prf), or in a group profile (if supported on your platform).

You can declare connections to more than one Netezza data source using the SET CONNECTION_ATTRIBUTES commands. The actual connection takes place when the first query is issued. If you issue multiple SET CONNECTION_ATTRIBUTES commands:

The connection named in the first SET CONNECTION_ATTRIBUTES command serves as the default connection.
If more than one SET CONNECTION_ATTRIBUTES command contains the same connection name, the adapter uses the attributes specified in the last SET CONNECTION_ATTRIBUTES command.

Procedure: How to Configure an Adapter

From the Web Console sidebar, click Connect to Data.

or

From the Data Management Console, expand the Adapters folder.

In the DMC, the Adapters folder opens. In the Web Console, the Adapters page opens showing your configured adapters.
In the Web Console, click the New Datasource button on the menu bar and find the adapter on the drop-down list or, in the DMC, expand the Available folder if it is not already expanded.
On the Web Console, you can select a category of adapter from the drop-down list or use the search option (magnifying glass) to search for specific characters.
In the DMC, expand the appropriate group folder and the specific adapter folder. The group folder is described in the connection attributes reference.
Right-click the adapter name and/or version and select Configure.

The Add Adapter to Configuration pane opens.
Enter values for the parameters required by the adapter, as described in the chapter for the specific adapter you want to configure.
Click Configure. The configured adapter is added to the Adapters list in the DMC resources tree or the Configured list in the Web Console.
In the Web Console, the adapter remains on the Available Adapters list with a check mark to indicate that at least one connection has been configured. You can configure additional connections from either the Configured or Available list by right-clicking the adapter and clicking Add Connection.

Reference: Connection Attributes for Netezza JDBC

The Netezza adapter is under the SQL group folder.

The following list describes the connection attributes for which you can supply values. To complete the attribute declaration, click the Configure button.

Connection name

Logical name used to identify this particular set of connection attributes. The default is CON01.

URL

Location URL for the Netezza data source.

Driver Name

Name for the JDBC driver.

See driver documentation for the specific release you are using.

IBI_CLASSPATH

Defines the additional Java Class directories or full-path jar names which will be available for Java Services. Value may be set by editing the communications file or in the Web Console. Using the Web Console, you can enter one reference per line in the input field. When the file is saved, the entries are converted to a single string using colon (:) delimiters for all platforms. OpenVMS platforms must use UNIX-style conventions for values (for example, /mydisk/myhome/myclasses.jar, rather than mydisk:[myhome]myclasses.jar) when setting values. When editing the file manually, you must maintain the colon delimiter.

Security

There are two methods by which a user can be authenticated when connecting to a database server:

Explicit. The user ID and password are explicitly specified for each connection and passed to the database, at connection time, for authentication.
Password Passthru. The user ID and password received from the client application are passed to the database, at connection time, for authentication.

User

Primary authorization ID by which you are known to the data source.

Password

Password associated with the primary authorization ID.

Select profile

Select a profile from the drop-down menu to indicate the level of profile in which to store the CONNECTION_ATTRIBUTES command. The global profile, edasprof.prf, is the default.

If you wish to create a new profile, either a user profile (user.prf) or a group profile if available on your platform (using the appropriate naming convention), choose New Profile from the drop-down menu and enter a name in the Profile Name field (the extension is added automatically).

Store the connection attributes in the server profile (edasprof).

Syntax: How to Declare Connection Attributes Manually

ENGINE SQLNEZ SET CONNECTION_ATTRIBUTES connection 
'URL'/userid,password

where:

SQLNEZ

Indicates the adapter. You can omit this value if you previously issued the SET SQLENGINE command.

connection

Is a logical name used to identify this particular set of attributes.

Note that one blank space is required between connection and URL.

URL

Is the URL to the location of the Netezza data source.

userid

Is the primary authorization ID by which you are known to the target database.

password

Is the password associated with the primary authorization ID.

Example: Declaring Connection Attributes

The following SET CONNECTION_ATTRIBUTES command connects to data source using the Netezza Driver, with an explicit user ID (MYUSER) and password (PASS). To ensure security, specifying connection attributes from the Web Console or DMC will encrypt the password before adding it to the server profile.

ENGINE SQLNEZ SET CONNECTION_ATTRIBUTES CON1
  'jdbc:xxxxxxx://hostname:port/datasource

Overriding the Default Connection

How to:

Change the Default Connection

If multiple connections have been defined, the connection named in the first SET CONNECTION_ATTRIBUTES command serves as the default connection. You can override this default using the SET DEFAULT_CONNECTION command.

Syntax: How to Change the Default Connection

ENGINE SQLNEZ SET DEFAULT_CONNECTION connection

where:

SQLNEZ

Indicates the adapter. You can omit this value if you previously issued the SET SQLENGINE command.

connection

Is the connection defined in a previously issued SET CONNECTION_ATTRIBUTES command. If this name was not previously declared, the following message is issued:

FOC1671, Command out of sequence

Note:

If you use the SET DEFAULT_CONNECTION command more than once, the connection name specified in the last command serves as the default connection.
The SET DEFAULT_CONNECTION command cannot be issued while an uncommitted transaction (LUW) is pending. In that case, the following message is issued:
```
FOC1671, Command out of sequence.
```

Example: Selecting the Default Connection

The following SET DEFAULT_CONNECTION command selects CON1 as the default connection.

ENGINE SQLNEZ SET DEFAULT_CONNECTION CON1
