OBIEE 11g Graphs Do not display after applying patch on 11.1.1.6.x

I have applied patch bundle 11.1.1.6.5 on my OBIEE 11.1.1.6.0. After applying the patch, I have noticed that none of my graphs/charts are displayed on the browser. I have deleted the browser cache and cookies, but still not displaying.

After referring the oracle support, I have did the following to resolve the issue.

We have customization for custom skins and styles in custom directory, so we did the below section first.

Section 1 Copy BIChart.swf  file to custom directory

1. Copied the BIChart.swf file from ORACLE_BI_HOME'bifoundation\web\app\res\sk_blafp\dvt directory to our custom directory

Custom directory located at <MW_HOME>/Oracle_BI/bifoundation/OracleBIPresentationServiceComponent/coreapplication_obips1/analyticsRes/<custom_dir>/dvt

2. Stop and Restart the BI Presentation Service components

cd <INSTANCE_HOME>/bin
opmnctl stopproc ias-component=coreapplication_obips1

opmnctl startproc ias-component=coreapplication_obips1

Section 2 Clear the managed server temporary files

1. Stop the Services
2. backup $DOMAIN_HOME/servers/bi_server1/tmp
3. cd $DOMAIN_HOME/servers/bi_server1/tmp
4. rm -rf * (including the hidden .internal directory)
5. Start the services

Now, open the browser and clear the cache and cookies.
Login to the analytics dashboard. If graphs/charts not visible, refresh the page by pressing ctrl+F5 (On Internet Explorer)

This should resolve the issue.
