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 * * * ?';

SheduledBatchable sch = new scheduledBatchable();

system.schedule('Hourly Example Batch Schedule job', time, sch);

 

*****If you want to run it as frequent as 15,30 or N mins .....
String time = '0 15 * * * ?' ;

String time = '0 30 * * * ?' ;

    System.schedule('Scheduled Job 1', '0 0 * * * ?', new ScheduledClass());
    System.schedule('Scheduled Job 2', '0 15 * * * ?', new ScheduledClass());
    System.schedule('Scheduled Job 3', '0 30 * * * ?', new ScheduledClass());
    System.schedule('Scheduled Job 4', '0 45 * * * ?', new ScheduledClass());

I am trying to add a double or single asterisk to lightning: input tags in LWC, by using "required" tag inside the tag I am able to see the asterisk, but two issues with this are I have to show a red asterisk to some conditionally mandatory issues.

The Developer Console didn't set the DEVELOPER_LOG trace flag on your user. Having an active trace flag triggers debug logging. You have 1,978 MB of the maximum 1,000 MB of debug logs. Before you can edit trace flags, delete some debug logs.

1. In developer console, Select tab "Query Editor" at the bottom of the console. 2. Select check box "Use Tooling API". 3. Execute the below query: SELECT Id FROM ApexLog   4. Select All Rows.
