Separating large objects from a shared pool increases the efficiency of shared pool memory, which means that it can use more memory to process new requests and to preserve existing data when needed.4.Java PoolCan be configured as a separate memory area in the SGASize is specified by the Java_pool_size parameterUsed to store all session-specific Java code and data in the JVM in memory5.

if manual management is used, then the PGA assigned to each session is not automatically returned to the system, regardless of whether the session is performing an operation or idle state, it must be returned to the system after the user exits (Log Off) of the PGA space. This can cause a lot of memory to be idle, and the session that really needs to work has not been able to get enough PGA, and in automatic management, once the operation of the session is finished, the Runtime-area will be auto

through an effective and simplified transmission pipeline, and it also has strong scalability, applications and components are highly decoupled to simplify deployment. Perhaps we need to understand this model. The most important concept is service components. Do not consider the internal services of the microservice architecture. It is best to consider service components. In terms of granularity, it can be small to a single module or as large as an a

lightweight micro-service architecture is described macroscopically, which provides a clear blueprint for the future exploration process. First, we start with architecture and architects, briefly review the process of architecture evolution and the development trend of micro-service, we believe that the emergence of micro-services is inevitable, and it will be i
