How to synchronize threads in oracle?

@aniya.jaskolski 

There are several ways to synchronize threads in Oracle, some of them are:

1. Using DBMS_LOCK package: This package provides functions and procedures to implement locks at the session or system level. You can use this package to create and manage locks to synchronize multiple threads.
2. Using DBMS_SCHEDULER package: You can use the DBMS_SCHEDULER package to create chain jobs that can be synchronized to run in a specific order. By setting dependencies between jobs, you can ensure that threads are executed in a synchronized manner.
3. Using triggers: You can create triggers on tables to control access to shared resources. By using triggers, you can ensure that only one thread can access a resource at a time.
4. Using PL/SQL packages: You can create custom PL/SQL packages that implement synchronization mechanisms such as semaphores or mutexes to control access to shared resources.

Overall, the choice of synchronization mechanism depends on the specific requirements of your application and the level of granularity at which you need to synchronize threads.
