Impact: SOA_INFRA is running only on one MS server when we have 4 Managed servers(Cluster) and also we are not able to see from wwwin.test.world.com/em
Under SOA_INFRA - only 1 Managed server is visible.
Description:
Coherence is an in-memory data grid which helps eliminate single points of failure and single points of bottlenecks in an application by distributing application objects and logic across multiple physical servers.
Oracle Coherence is the industry leading in-memory data grid solution that enables organizations to predictably scale mission-critical applications by providing fast access to frequently used data.
– Coherence is bundled with WLS 10.3.3 and above.
.
– Make sure you download the Package Installer for WLS which includes Coherence.
Example: The installation of WebLogic Server 11gR1 (10.3.3) also installs Coherence 3.5 in the
coherence_3.5 directory
Important terms :
Coherence Node – a Java process – it is an instance of coherence server – has well known ports and address to communicate with other nodes.
Coherence Cluster – Group of storage enabled cluster nodes – specified by a common cluster name
Coherence Client – Storage disabled nodes.do not hold data but perform data operations
Coherence Server – Storage enabled nodes. Hold Cache Data and performs server processing
Cache – Local memory space that holds frequently requested data
Fix : wka cluster settings were missing after adding issue fixed.
