Few 11g questions I found in the support log

A few useful things I found about 11G.

1.

Goal

In OBIEE 11g there is no link on the homepage for “Oracle Answers” like there was in the 10g version. Where is it or how to get it to appear?

Solution

BIEE 11g has been re-engineered in 11g, especially with the inclusion of WebLogic in the mid tier. A new look and feel is displayed from the 10g version. Now when connecting in 11g BIEE, you basically see Answers.

On the main 11g page, some of the latest Dashboards and Reports that have been created are displayed, plus there are still links to create a new report or open another dashboard.

So it is more a look and feel (cosmetic) change than anything else as the same functionality exists in both versions.

Symptoms
In OBIEE Presentation Server log, you may see the following warning messages:

11g xml data incompatibility: object [some object type] at [the object path] requires upgrade. Admin needs to rerun upgrade, or remove the object, or fix the object’s xml manually. If problem persists, please contact technical support
Cause
========
Reason
========

Customers did not run catalog upgrade from the previous 11g version to the current version. Therefore, we have to upgrade it at run time in memory without saving it (if the catalog is upgraded through upgrade process, it will be upgraded and saved permanently in the catalog.) We give this warning message to warn customers that it is recommended to perform the catalog upgrade otherwise the application will need to perform the upgrade in memory.

Solution
The resolution for the issue has been documented. It is suggested to use the following:

Please refer to section: 3.8.10.2 Updating Oracle Business Intelligence Catalogs in
Oracle® Fusion Middleware Patching Guide 11g Release 1 (11.1.1.5.0). Here is the link to the documentation.

Oracle® Fusion Middleware Patching Guide 11g Release 1 (11.1.1.5.0)

The following bug has been logged to address the issue

Bug 12911878 – ERROR “11G XML DATA INCOMPATIBILITY” WHEN MOVING FROM 11.1.1.3 TO 11.1.1.5

Symptoms
You are upgrading OBIEE 10g to OBIEE 11g using the Upgrade Assistant.  You have upgraded the repository successfully, but when you upgrade the web catalog, you get the following error:

[2011-03-09T13:38:25.565-05:00] [BIEE] [ERROR] [] [upgrade.BIEE] [tid: 13] [ecid: 0000IuRtnAxFw000jzwkno1DTwWL000004,0] javax.management.RuntimeMBeanException: Cannot refresh – Currently locked[[
at oracle.as.jmx.framework.standardmbeans.spi.OracleStandardEmitterMBean.doInvoke(OracleStandardEmitterMBean.java:897)

Cause
There is a lock on the web catalog in Enterprise Manager.

Solution
1. Search through Enterprise Manager and release any locks.
2. Stop and re-start Weblogic and the managed servers.
3. Start Upgrade Assistant and try upgrading the web catalog again.
