How to access content from previous IBM Cognos release from within the IBM Cognos 10 portal?

Technote (FAQ)


Question

Describes the procedure to make content from a previous IBM Cognos release (8.4 for example) available within the IBM Cognos 10 portal. Also known as multi-version coexistence

Answer

Cognos 10 Multi-Version Coexistence is supported with Cognos 8.3.x, 8.4.x and 8.4.1. While Cognos 8.4.1 requires no updater, one may be required for Cognos 8.3 FP5 and 8.4.x. Below are the minimum build numbers required for these versions. These can be found and confirmed in the cmplst.txt file.

  • IBM Cognos 8.3.86.1045
  • IBM Cognos 8.4.29.1331

Note:
  • Please contact IBM Cognos Support to request access to these updater versions.
  • Planning is not supported.


Implementation Details:

NOTE: Ensure that your 'Gateway URI' value is correct on all application tier instances. This value is used to form links to content.

A : In your IBM Cognos 10 portal:

1) Go to the Launch->IBM Cognos Administration page
2) Under the Status tab, click the System link
3) In the scorecard pane, click the triangle next to the System entry and choose Set Properties
4) Click on the Settings tab.
5) Click the Edit link under the Environment->Advanced Settings row
6) Add the following advanced variables and their corresponding values:


Variable
Value
MVC_remoteWebContent http://<hostname>.<domain>/<c8alias>
MVC_remoteGateway http://<hostname>.<domain>/<c8alias>/cgi-bin/cognos.cgi
(see note a below)
MVC_domain <domain>
(see note b below)

Note:

(a) You can get the MVC_remoteGateway value from the IBM Cognos 8.4's Cognos Configuration tool under the Environment section. It is the "Gateway URI" entry under the "Gateway Settings" section.

(b) The MVC_domain variable should only be added if using 8.4.1 FP4 or higher release

7) You will need to ensure the domain name (for example: ibm.com) associated with the <hostname> used above is added to the Security->IBM Cognos Application Firewall's "Valid domains or hosts" property in the IBM Cognos 10's Configuration tool. Additionally, make sure all other entries in this section match with the IBM Cognos 8.4 "Valid domains or hosts" property. Then restart the IBM Cognos 10 service.


B : In your IBM Cognos 8 portal:

1) Go to the Launch->IBM Cognos Administration page
2) Under the Status tab, click the System link
3) In the scorecard pane, click the triangle next to the System entry and choose Set Properties
4) Click on the Settings tab.
5) Click the Edit link under the Environment->Advanced Settings row
6) Add the following advanced variable and the corresponding value:

Variable
Value
MVC_gateway http://<hostname>.<domain>/<c10alias>/cgi-bin/cognos.cgi
(see note a below)
MVC_domain <domain>
(see note b below)

Note:

(a) You can get the MVC_gateway value from the IBM Cognos 10's Cognos Configuration tool under the Environment section. It is the "Gateway URI" entry under the "Gateway Settings" section.

(b) The MVC_domain variable should only be added if using 8.4.1 FP4 or higher release

7) You will need to ensure the domain name (i.e. ibm.com) associated with the <hostname> used above is added to the Security->IBM Cognos Application Firewall's "Valid domains or hosts" property in the IBM Cognos 8.4's Configuration tool. Additionally, make sure all other entries in this section match with the IBM Cognos 10 "Valid domains or hosts" property. Then restart the IBM Cognos 8 service.

C : Adding a link in the IBM Cognos 10 portal to view IBM Cognos 8.4 content:

1) Within the IBM Cognos 10 portal, you should now see a new button link ("Link to Content from a Remote System") on the Public Folders page to the left of the scissors (Cut) button link.

2) Click this link and give a name to the link you will create that will reside in the IBM Cognos 10 portal. (e.g. c84content). Click the Next button

3) Under the Starting folder, click the "browse" link. You should now see the Public Folders of the IBM Cognos 8 release. Choose the package or folder you want to be able to access within the IBM Cognos 10 portal or to access the Public Folders in the IBM Cognos 8.4 release just click the OK button. This will automatically select "Cognos > Public Folders" to display. Click Finish button.

4) In the Public Folders of IBM Cognos 10 portal, you will now see a link called "c84content". Click this link to see the IBM Cognos 8.4 content.
