Cache Fusion Hardening
Availability → Real Application Clusters
The Global Cache Service (LMS) process is vital to the operation of an Oracle Real Application Clusters (Oracle RAC) Database. Cache Fusion Hardening helps to ensure that the critical LMS process remains running despite some discrepancies between instances that would otherwise lead to a LMS and consequently database instance failures.
全局缓存服务（LMS）进程对于Oracle Real Application Clusters（Oracle RAC）数据库的运行至关重要。 尽管实例之间存在一些差异，但Cache Fusion Hardening有助于确保关键的LMS进程保持运行，否则可能会导致LMS进而导致数据库实例故障。
Business Benefit: Cache Fusion Hardening increases availability by reducing outages particularly in consolidated environments in which multiple Pluggable Databases (PDBs) are operated in the same Oracle RAC Container Database.
Cache Fusion Hardening通过减少中断来提高可用性，尤其是在其中在同一Oracle RAC容器数据库中运行多个可插拔数据库（PDB）的整合环境中。
