Remediation/Fixes

1. Download IBM JRE 8 (8.0-5.40) from: <http://www.ibm.com/support/fixcentral&gt; by keyword ‘Runtimes for Java Technology’. (The following steps use x86_64 as an example.)
2. Copy JRE package into the Explorer Server host and Explorer Node host(s).
3. On the Explorer Server host, stop webgui and explorer services
4. On the Explorer Server host, extract new JRE files and replace old JRE files in the following directory:

$PERF_TOP/…/…/…/jre
5. On the Explorer Server host, start webgui and explorer services on demand.
6. On the Explorer Node host, stop plc service.
7. On the Explorer Node host, extract new JRE files and replace old JRE files in the following directory:

$PERF_TOP/jre
8. On the Explorer Node host, start plc service.
