How to get sound in Facebook videos on Safari Browser - Apple MacBook Pro

After the OS update to "MacOS Sierra" Facebook videos were playing without any sound on Apple MacBook Pro. Youtube was working fine without any issues. Below steps helped me to fix the issue.

1) Login to Facebook
2) Play the video.
3) Hover on the tab. A speaker button should appear. Please note that this button will be enabled only after playing the video.


4) Click on that to Unmute.




This should fix the problem.

OBIEE MDS-01370: MetadataStore configuration for metadata-store-usage "OWSM_TargetRepos" is invalid.

I did a simple install of OBIEE on my windows 7 64 bit machine. After installing, i was able to login to the Console and Enterprise manager. But I was unable to login to the analytics URL using the same weblogic credentials. I was getting the below error

I checked the BI services, all the BI services were running properly, then I logged into the Enterprise manager and found the below log file

Message    MDSConfigurationException encountered in parseADFConfigurationMDS-01330: unable to load MDS configuration document

Solution:
Later found that I did run the below commands before running the RCU

set RCU_JDBC_TRIM_BLOCKS=TRUE

echo %RCU_JDBC_TRIM_BLOCKS%

Please stop all the services including admin server, BI services and manager server.

Drop the RCU and do a fresh install of the RCU with the same password you used before for DEV_BIPLATFORM schema.

Restart the services again. You should now be able to login to the analytics
