IBM Cognos 8 supports DB2 data sources. DB2 connection types can be used to connect to DB2 Linux/UNIX/Windows, Db2 zOS, and DB2 i5OS.
You specify connection parameters when you create a data source or modify
a data source connection
.
Parameter | Description |
DB2 database name | Enter the name (alias) of the DB2 database that was used when the DB2 client was configured. |
DB2 connect string | Optional. Enter name/name value pairs that DB2 or ODBC vendors can accept. |
Collation sequence | Enter the collation sequence to be included in the database connection string. Collation sequences are required only in rare cases where there may be sorting discrepancies between IBM Cognos 8 and a database. We recommend that you contact customer support before using a collation sequence. |
Open asynchronously | Not used. |
Trusted context | Select this check box to allow IBM Cognos 8 to attempt a trusted connection to an appropriately configured DB2 server. For more information, refer to the DBA/DB2 documentation. If you select this check box with a client or server that does not support the feature, you may get a connection error or a report execution error. |
Timeouts | Specify the time in seconds within which you want the database to connect or wait for your reply before timing out. Valid entries are zero to 32,767. To have the database wait indefinitely, enter zero, which is the default. |
Signon | For more information on signon, see Securing Data Sources. If no authentication is required, click No authentication. If authentication is required, click Signons. If a user ID and password is required in the connection string, select the User ID check box. If a password is required, select the Password check box and enter the password in the Password and Confirm password boxes. To create a user ID and password that automatically connects to the data source, click Create a signon that the Everyone group can use. Enter the User ID and then enter the password in the Password and Confirm password boxes. |
