How to run a scheduled job every 15 mins?
You can write a Batch Class and then Schedule it with the help of a scheduler.Let me explain it to you with the help of an example: BATCH CLASS : global class test_BATCH implements Database.Batchable<sObject> { global (Database.QueryLocator | Iterable<sObject>) start (Database.BatchableContext BC) { String query = 'SELECT Id,Name FROM Account'; return Database.getQueryLocator(query); } global void execute (Database.BatchableContext BC, List<Account> scope) { for(Account a : scope){ a.Name = a.Name + 'Updated'; } update scope; } global void finish (Database.BatchableContext BC) { } } SCHEDULABLE CLASS : global class scheduledBatchable implements Schedulable { global void execute(SchedulableContext sc) { test_BATCH b = new test_BATCH(); //Parameters of ExecuteBatch(context,BatchSize) database.executebatch(b,10); } } ***Note: if batch size is not mentioned it is 200 by default. CUSTOM TIMING String time = '0 0 * * * ?'...
