Charts in BI not rendering after applying OBIEE 11.1.1.6.2BP1

Issue:  Charts are no longer rendering in IE or FF after applying OBIEE 11.1.1.6.2 BP1

The reason that charts are failing to render is due to the fact that our update process does not touch the custom directories (skins, styles). It will only update the default skins and styles directories (s_blafp and sk_blafp). The reason is that we do not want to overwrite any customizations done by customers / partners.

Note: If you are using a custom skins directory, you will have to copy the BIChart.swf from the default directory or the install directory into your custom skins directory. If you do not replace the file, the charts will not render. This change requires that the OracleBI Presentation Services Component be restarted via the opmnctl process as well as for the browser cache to be cleared. Once that has been done, you will be able to render the charts.

OBIEE 11.1.1.6.0 - Import Metadata from Oracle Database is not working with BI Client installer

BI Client installer (version 11.1.1.6.0) does not install Oracle Database Client. Therefore for BI Admin tool client installations, the Oracle DB Client (11gR2) must also be separately installed on same windows machine.

Tip: If you install BI Client 32bit version, make sure to install Oracle Database Client 32bit version. Likewise If you install BI Client 64bit version then make sure to install Oracle Database Client 64bit version.

OBIEE 11.1.1 - BI Office Intermittent Timeout Errors

In OBIEE releases 11.1.1.5 / 11.1.1.6, if the BI Office Server is configured to connect to Presentation Services through Oracle HTTP Server (OHS), then you might see intermittent error messages that are caused by the timeout of a request. To work around this issue, increase the Keepalive timeout 50 or more.

OBIEE 11.1.1 - Unable to View PDF / graphs in Internet Explorer 7 and 8 over SSL using WebGate/OHS as front-end

Set CachePragmaHeader and CacheControlHeader to public.

This setting applies only to WebGates. These settings control the browser's cache. By default, CachePragmaHeader and CacheControlHeader are set to no-cache. This prevents WebGate from caching data at the Web server application and the user's browser. However, this may prevent certain operations such as downloading PDF files, saving report files and displaying charts when the site is protected by a WebGate. You can set the Access Manager SDK caches that the WebGate uses to different levels. See http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html section 14.9 for details. All of the cache-response-directives are allowed.

Tips:

1. For your OBIEE setup using WebGate, you may need to set both (CachePragmaHeader and CacheControlHeader) cache values to public.

2. For your OBIEE setup using OHS with mod_osso, to allow caching for SSO protected resources you need to add "OssoSendCacheHeaders off", in mod_osso.conf.

OBIEE 11.1.1 - Upgrade from 10g - Calculated Items

In 10g, calculated items were created in one pivot table only. In 11g, all calculated items are shown in all views.

The format of the report is modified: calculated items that were in one pivot table only before the upgrade now appear in all views.

If a calculated item had the option ‘Hide details’ selected, showing this column in other views changes completely the results.

To replicate 10g behavior in 11g, you must:

Add a new column identical to the one used to compute the calculated item.

In all views except in the one that includes the calculated item, replace the old column by the new one.

Note that it is easier to perform this modification in 10g before the upgrade. It is possible to do it in 11g after the upgrade but then you have to compare 11g and 10g reports to find out which view the calculated item belonged to.

OBIEE 11.1.1 - Troubleshooting OCI Connections

If you are having trouble connecting to an Oracle Database using OCI, check to ensure that the following conditions are true:

■ The computer running the Oracle BI Server must use Oracle Call Interface (OCI) to connect to the database.

■ If you choose not to use the entire connect string in the repository connection pool, you must ensure that a valid tnsnames.ora file is set up in the following location within the Oracle Business Intelligence environment, so that the Oracle BI Server can locate the entry:

ORACLE_HOME/network/admin

■ If you choose not to use the entire connect string in the repository connection pool, ensure that the net service name in the tnsnames.ora file matches the Data Source Name used in the connection pool.

OBIEE 11.1.1 - Error: "Too many running queries. Server is too busy to process any more queries at this time"

Symptoms:

During normal users load, OBIEE fails frequently with the following error:

"OAMP2OPY:GIQKCQ7 Too many running queries. Server is too busy to process any more queries at this time."

Possible Causes / Solution:

1. The Oracle Database instance is configured by default to run only 150 PROCESSES; the maximum load for dedicated connections is determined by the PROCESSES parameter. When the listener believes the current number of connections has reached maximum load, it may set the state of the service handler for an instance to "blocked" and begin refusing incoming client connections with the following error (in biserver1.log set in debug level):

"TNS-12516 TNS:listener could not find instance with matching protocol stack"

Tip: Verify the Oracle database processes parameter setting.  It is also a good idea to make sure the Oracle database sessions and open cursors settings are large enough.

2. Increase the number of concurrent client connections (sessions) to OBI server. Each client request to OBI Server uses one SERVER_THREAD. Each SERVER_THREAD uses 0 or more DB_GATEWAY_THREADs depending upon the number of DB queries executed. Following NQSConfig.INI parameters need to be tuned (refer to OBIEE tuning guide for details on initial values to be set):
[ SERVER ]
MAX_SESSION_LIMIT
SERVER_THREAD_RANGE
DB_GATEWAY_THREAD_RANGE

3. Cleanup Web catalog via instanceconfig.xml using the steps documented in "Validating the Catalog" in System Administrator's Guide for Oracle Business Intelligence Enterprise Edition.

4. In instanceconfig.xml file for each instance, add the following parameters within Cache/Query tags:

<Cache>

       <Query>

           <MaxEntries>10000</MaxEntries>

           <AbsoluteMaxEntries>20000</AbsoluteMaxEntries>

           <CruiseEntries>3000</CruiseEntries>

           <ForceLRU>true</ForceLRU>

       </Query>

</Cache>

5. Make sure you have enough system resources available on BI Servers (sawserver, nqsserver).

6. Unstable network connection link between OBIEE servers and Database server.
