When a Linux server is serving many concurrent requests to read many different files, does it: Seek to File_1, read the entire file, then seek to File_2, read the entire file, then seek to File_3, etc etc...Usage of the concurrent queue will enable your application to allow multiple threads to read or write to the queue without the need of an explicit lock synchronization will be taken care of by the concurrent queue. The ConcurrentQueue represents a lock-free, thread

Concurrent programs in oracle apps is defined as the system batch jobs that retrieve data from or push data into oracle database. They are defined in oracle applications as executables such that you can access it any time and schedule it as you want.
- If your application does need to prevent accidental data loss in concurrency scenarios, one way to do that is to use database locks. This is called pessimistic concurrency . For example, before you read a row from a database, you request a lock for read-only or for update access.
- This is a classic producer-consumer problem. Essentially what you have is multiple threads trying to write to the same resource (your file). You have a few different options on solving this depending on how you want your program to perform.
- You can parallelise reading a large file provided you have multiple independent spindals. E.g. if you have a Raid 0 + 1 stripped file system, you can see a performance improvement by triggering multiple concurrent reads to the same file.
- Concurrent dictionary is thread-safe collection. It is used to store key-value pair in multi-threaded environment. It is used to store key-value pair in multi-threaded environment. Add: Add item into concurrent dictionary.
