Oracle jobs regularly execute stored procedures to refresh materialized views and record exceptions
In Oracle, jobs regularly execute stored procedures to refresh the materialized view and record exceptions (My materialized view cannot be refreshed by myself)

This article provides a detailed analysis of the implementation of Oracle SQL statements for querying and deleting jobs, for more information about how to query and delete duplicate records, see SQL statement 1. For more information about duplicate records in a table, see select * frompeoplewherepeopleIdin (selectpeopleIdfr ).
This article provides a detailed analysis of the implementation of
[Oracle] jobs for beginners: a job is an oracle object. It can be understood as a program for scheduled execution. Objective: To automatically execute specific code at regular intervals-create a job

Select t. *, t. rowid from dba_jobs t;
Select t. *, t. rowid from sys. user_jobs t;
Select job, last_date, next_date, broken, interval, failuresFrom user_jobs;
When a job returns an error, Oracle tries to execute it again. The first attempt is one minute later, the second attempt is two minutes later, and the third attempt is four minutes later, and so on. The cycle of each attempt is doubled until the nex
Analysis and Processing of Oracle jobs not executed
Steps:1) Check the last date, next date/failure times, broken, and check whether the job fails to run multiple times because of the exception or deadlock in the Stored Procedure executed by the job, it is automatically broken. This is usually the cause of most problems in database development. Run the following statement to view the job running status:
