May 20, 2016 · The simplest possible approach would be to use the old, despported dbms_job package and just do a dbms_job.submit with the DML you want to run in a separate session. The preferred approach would be to set up one or more jobs using dbms_scheduler and to set up a chain to run them with whatever dependencies you want.

Feb 19, 2014 · For PL/SQL Parallel processing you have the following options: DBMS_SCHEDULER (newer) DBMS_JOB (older) Parallel Query; These will let you "emulate" forking and threading in PL/SQL. Of course, using these, you may realize the need to communicate between parallel executed procedures. To do so check out: Advanced Queuing; DBMS_ALERT; DBMS_PIPE

Jul 17, 2017 · The best way to solve your problem is to avoid applying PL/SQL to a result set and rewrite your query to use plain SQL only. Under Oracle this is especially true since you avoid the costs of switching between SQL and PL/SQL contexts.

Given a query plan for a SQL query, the parallel execution coordinator breaks down each operator in a SQL query into parallel pieces, runs them in the right order as specified in the query, and then integrates the partial results produced by the parallel execution servers executing the operators.

Nov 10, 2010 · Enhance customers' Oracle database performance by using parallel SQL with an Oracle parallel hint, enabling a SQL statement to be simultaneously processed by multiple threads or processes.

May 12, 2017 · THREADED_EXECUTION=TRUE: Oracle runs with the multithreaded model. To switch to the multithreaded model, simply set the THREADED_EXECUTION parameter and restart the database. CONN sys AS SYSDBA ALTER SYSTEM SET threaded_execution=TRUE SCOPE=SPFILE; SHUTDOWN IMMEDIATE; STARTUP;

Apr 30, 2016 · Purpose of this document is achieve multi threading within a PL/ SQL code to improve the performance. Function f is executed serially, 100 times one after another.

Pro*C/C++ allows your application to define a handle to a runtime context, and pass that handle from one thread to another. For example, an interactive application spawns a thread, T1, to execute a query and return the first 10 rows to the application. T1 then terminates.

Apr 14, 2023 · Process bulk data sets quickly by using multi-threading to run parallel processing. Speed up database backups and recoveries by using multi-threading to execute them simultaneously. Optimize complex queries by breaking them down into smaller, concurrent tasks.

Jun 22, 2012 · After you run send your query to Oracle, it has to do 3 things: Technically it has to do at least 2 things, and sometimes only 1. But, to get the data back to the user, the fetch must occur. If you have a 10 row query or a 1,000,000 row query, this can mean 1 or many fetches in groups of records.
