How to enable/disable observation mechanism in CQ5 JCR Repository?

[Former Community Member]

Hi,

 I have been working with observation for few days and came to know that repository has supports observation via this lines of code  

       Repository.OPTION_OBSERVATION_SUPPORTED.

But what am excepting to know that is "where the observation configuration done in jcr repository"?

Is there any possible ways to enable/disable the observation mechanism .If it is where and how it can be achieve through coding?

Any suggestions would be appreciated here.

Thanks in advance
