We define process migration as the transfer of a sufficient amount of a process’s state from one machine to another for the process to execute on the target machine. This paper surveys proposed and implemented mechanisms for process migration.
What is process migration draw flow of process migration?
Process migration is the act of transferring a process between two machines. It enables dynamic load distribution, fault resilience, eased system administration, and data access locality. Despite these goals and ongoing research efforts, migration has not achieved widespread use.
What is meant by process migration?
Process Migration refers to the mobility of executing (or suspended) processes in a distributed computing environment. … Sometimes the term is used to describe the change in execution from one processor to another processor within the same machine.
What is process migration list the steps for it?
Process Migration Mechanisms Four major activities 1. Freezing the process on its source node and restarting it on its destination node. 2. Transferring the process’s address space from its source node to its destination node.
What is process migration explain in detail the different method of address space transfer mechanism?
Process migration mechanism consists following four steps : 1) Freezing the process on its source node and restarting it on its destination node. 2) Transferring the process’s address space from its source node to its destination node. 3) Forwarding messages meant for the migrant process.
What are characteristics of process migration?
Process migration is the act of transferring a process between two machines. It enables dynamic load distribution, fault resilience, eased system administration, and data access locality.
Why process migration is required?
Process Migration is the ability of a system (operating system or user-space program) to transfer processes between different nodes in a network. The motivations behind process migration are to balance load, improve availability, enhance communication performance and ease system administration.
What are the factors affecting migration?
Migration is affected by various factors like age, sex, marital status, education, occupation, employment etc. Age and sex are main demographic factors that affect the migration.
What are the types of migration?
internal migration: moving within a state, country, or continent. external migration: moving to a different state, country, or continent. emigration: leaving one country to move to another. immigration: moving into a new country.
Is a migration?
Migration is the movement of people from one place to another. Migration can be within a country or between countries. … Some people decide to migrate, e.g. someone who moves to another country to improve their career opportunities. Some people are forced to migrate, e.g. someone who moves due to famine or war.
How is data migration done?
Data migration includes data profiling, data cleansing, data validation, and the ongoing data quality assurance process in the target system. … To convert it, data must be extracted from the source, altered, and loaded into the new target system based on a set of requirements.
What are characteristics of process migration Mcq?
|Que.||What are characteristics of process migration ?|
|a.||transfer data by entire file or immediate portion required|
|b.||transfer the computation rather than the data|
|c.||execute an entire process or parts of it at different sites|
|d.||none of the mentioned|
Why process migration is important in distributed system?
Process migration may be used to improve the performance of a distributed system in a number of areas. … When the process has used the reso urce, it may be migrated back to its original host. These issues are as important in persistent systems as they are in non-persistent systems. They may even be more important.
What are the desirable features of a good process migration mechanism?
The desirable process of a good process migration mechanism are: Transparency, that is, Object access level transparency to support non pre-emptive process migration, and System call and inter-process communication-level transparency to support pre-emptive process migration facility.
