1. Download IBM JRE 7 from the following location: http://www.ibm.com/support/fixcentral. (The followings steps are using x86_64 as an example.)
2. Copy JRE package into the Analytics Server host and Analytics Node host(s).
3. On the Analytics Server host, stop pats, pars, and parb services
4. On the Analytics Server host, extract new JRE files and replace old JRE files in following directories

#{ANALYTICS_SERVER_TOP}\jre

#{ANALYTICS_SERVER_TOP}\report\jre

Where ANALYTICS_SERVER_TOP describes the top-level IBM Spectrum LSF Analytics server installation directory.

5. On the Analytics Server host, start pats, pars, and parb services on demand.
6. On the Analytics Node host, stop plc services
7. On the Analytics Node host, extract new JRE files and replace old JRE files in following directory

#{ANALYTICS_NODE_TOP}/jre/#{ARCH}/

Where ANALYTICS_NODE_TOP describes the top-level IBM Spectrum LSF Analytics node installation directory. ARCH describes the architecture of Analytics Node host. E.g. linux-x86_64

8. On the Analytics Node host, start plc service.
