Concurrent Requests programs managers oracle applications:-
Oracle applications – Concurrent Requests, Concurrent Programs, Concurrent Processes, Concurrent Managers will be discussed here.Concurrent manager is an important term that an Oracle Applications DBA encounters frequently.Managing and maintaining concurrent manager is an essential role/function of a DBA.
What is concurrent processing?
Concurrent processing is the process of executing programs in background simultaneously with the online operations (i.e executing foregroun abd background operations simultaneously. In LINUX/UNIX, we can get list of foreground operations using the command fg, background operations using the command bg).
Concurrent processing facility is available in Oracle applications.Most of the background operations are report generation programs.A person with the system administrator responsibility has the privilege to control the number of OS processes associated with running a program.
What is a concurrent request?
When a program is scheduled to be run as a background job, the program to generate the report/program to be run is the concurrent request.Lets say a shell script report.sh is to be run
shell# ./report.sh – concurrent request – this invokes process and can be looked at by issuing :
shell#ps -ef|grep report.sh – This outputs a process lisitng. It is concurrent request.
What is a concurrent program?
The script report.sh is the concurrent program.
What is a concurrent manager?
To start a concurrent program we need a concurrent manager. whenever there is a request to start a concurrent program, the request is inserted into a database table. The request is uniquely identified by a request ID. These requests from tables are read by the concurrent manager. Concurrent managers definition has information on how many operating system (OS)processes are to be dedicated to run the concurrent requests. These processes are referred to as target processes
