I haven't worked on Batch/Scheduler class before.In our org we have an existing scheduler class written as below:
Apex Class:
global with sharing class SchedularForBatchApex implements Schedulable {
global void execute(SchedulableContext sc) {
String CLASS_NAME1 = 'Actual__c';
try {
BatchTargtUpdate b = new BatchTargtUpdate(CLASS_NAME1);
Database.executeBatch(b);
}catch(Exception ex){
system.debug('Exception in BatchTargtUpdate(Actual__c) Execute Process submision and error is--->'+ex);
BatchUtil.trackErrorLogs(CLASS_NAME1, 'Execute', 'Exception Line Number:' + ex.getLineNumber() + '~ Exception Type-' + ex.getTypeName()+ '~ Exception Message-' + ex.getmessage());
}
String CLASS_NAME2 = 'Revenue_Actual__c';
try {
BatchTargtUpdate b1 = new BatchTargtUpdate(CLASS_NAME2);
Database.executeBatch(b1);
}catch(Exception ex){
system.debug('Exception in BatchTargtUpdate(Revenue_Actual__c) Execute Process submision and error is--->'+ex);
BatchUtil.trackErrorLogs(CLASS_NAME1, 'Execute', 'Exception Line Number:' + ex.getLineNumber() + '~ Exception Type-' + ex.getTypeName()+ '~ Exception Message-' + ex.getmessage());
}
String CLASS_NAME3 = 'Direct_Revenue_Actual__c';
try {

Database.executeBatch(b);
}catch(Exception ex){

}
if u can see 17 jobs are calling in one scheduler class.As per my knowledge(theoretical ) only 5 batch jobs can be active at the same time.there could be possibility that rest 12 jobs are in queue.Values that we are passing in CLASS_NAME1,CLASS_NAME2..... are the custom setting values. and we run this scheduler only when we receive data from 3rd party application .It does not have fix timing.we schedule this job at anytime.
I just want to know how can do chain job here.
Can someone please help me best practice of writing multiple batch job in one scheduler class?
