Data source items are now synchronized with the model.

Connecting to an IQD Data Source

You can use Impromptu Query Definition (IQD) files to access data from local or
server-based databases, even if you do not have IBM Cognos Impromptu installed
on your modeling computer.

The .iqd file types requires that the

Series 7 IQD Bridge

component be installed.

This component must be installed on platforms supported by IBM Cognos Series 7
.4. The data sources used with the .iqd files must also be supported on the same
platforms.

For compatibility between the newer versions of IBM Cognos BI and versions prior
to 8.3, you must specify your IQD data source connection information in the
cs7g.ini file. This file is located in the

installation_location

/CS7Gateways/bin

directory.

When your IQD data source resides on a UNIX server, to change the connection
information for the data source, you must first update the model on your
Windows modeling computer and then re-deploy the model to the UNIX server.

To review an up-to-date list of environments supported by IBM Cognos products,
visit the IBM Cognos Customer Center http://www.ibm.com/software/data/
cognos/customercenter.

Isolation Levels for an IQD Data Source

When you create a data source in Cognos Transformer using an IQD, you must
specify an isolation level, typically the same one as was used when the .iqd file
was created. This is necessary so that the data is processed properly in the model.

If you must change the

Isolation level

, you can do so when you create your data

source using the

New Data Source

wizard, or later, from the

Data Source

property

sheet.

The following table describes the IQD isolation levels available for selection in
Cognos Transformer.

Isolation level

Description

Default

Uses the isolation level that was originally specified in IBM
Cognos Impromptu when the .iqd file was created.

Read Uncommitted

Makes changes made by other transactions immediately
available to a transaction.

Read Committed

Allows a transaction access only to rows that were committed
by other transactions.

Cursor Stability

Prohibits other transactions from updating the row on which
a transaction is positioned.

Reproducible Read

Ensures that rows selected or updated by one transaction are
not changed by another transaction until the first transaction
is complete.
