All customers are fulfilled its needs like getting the loan from the bank and no customer waits. If we see real-life example then customers in the bank are similar to processes on the computer. There are also ways by which we can prevent deadlock. In that case, the process runs and all resources allocated to that process and it is a non-preemptive process. In banker algorithm, we calculate the resources needed by the process before it goes in the run state. So bank works like that way in which all customers satisfied. In a bank there are customers and the bank gives the loan. There is also banker algorithm used to avoid deadlock. for i1 to n, m>resources and n>processes. Initialize work with available and finish i false. Step 1: Work and finish the 2 vectors of size m & n. So we prefer the safe state to avoid deadlock. To avoid deadlocks the process should inform the system that how many resources that a process should request for its execution. In the unsafe state, there are multiple processes running and requesting resources that may cause a deadlock to occur. In that case, all processes requesting resource will be fulfilled as no other process is running at a time. The deadlock avoidance method is suitable for smaller databases whereas the deadlock prevention method is suitable for larger databases. Safe state is that in which we run processes in sequence. Deadlock Avoidance: When a database is stuck in a deadlock, It is always better to avoid the deadlock rather than restarting or aborting the database. There are some techniques used to avoid deadlocks. This modified banker's algorithm performs the process arrangement on the basis of their needs that leads to solve the problem in less time.Deadlock is a state in which a process is waiting for the resource that is already used by another process and that another process is waiting for another resource. It also gives details about all the resources and processes that which one requires resources and in what quantity. In this research an approach for Dynamic Banker's algorithm is proposed which allows the number of resources to be changed at runtime that prevents the system to fall in unsafe state. The number of resources is not allowed to go down while it is in execution. Number of processes is static in algorithm, but in most of system processes varies dynamically and no additional process will be started while it is in execution. It needs to know how much of each resource a process could possibly request. Banker's algorithm can be described as deadlock avoidance and resource allocation algorithm which ensure the execution safety by simulating the allocation of already determined maximum possible of resources and makes the system into s-state by checking the possible deadlock conditions for all other pending processes. This also allocates the resource automatically to the stopped process for the execution and will always give the appropriate safe sequence for the given processes. It also give details about all the resources and processes that which one require resources and in what quantity. The number of resources are not allow to go down while it is in execution. The basic problem that used to happen was that ASP.NET would limit the number of threads that it allowed anything to use and web requests were handled on I/O threads, so incoming web requests would consume all of the available threads and IO completion for outstanding (asynchronous) calls would be queued up behind the very web requests that were. Number of processes are static in algorithm, but in most of system processes varies dynamically and no additional process will be started while it is in execution. Banker's algorithm referred to as resource allocation and deadlock avoidance algorithm that checks for the safety by simulating the allocation of predetermined maximum possible of resources and makes the system into s-state by checking the possible deadlock conditions for all other pending processes.
