Apex Run multiple batch jobs sequentially

We can run 3 batch jobs sequentially by incrementing the jobCounter and passing the integer (job index) into the batch scope

This can be increased to any amount of batch jobs, the problem I solved was able to update the Contact and disable Users in the same code running as different batch job.

As you cannot call @future in a batch method this solves by running each update in their own batch = transaction 👍🏻

global with sharing class App_Job_Account_Delete implements System.Schedulable, Database.Batchable<Integer>, Database.Stateful, Database.AllowsCallouts  {
    private List<JobError> jobErrors = new List<JobError>();
    global Integer jobCounter = 1;
    public void execute(SchedulableContext sc) {
        Database.executeBatch(this, jobCounter);
    }
    public Integer[] start(Database.BatchableContext context) {
        return new Integer[] {jobCounter};
    }
    public void execute(Database.BatchableContext context, Integer[] scope)     {
        try{
            if (isSandbox() || Test.IsRunningTest()){
                if(scope[0] == 1) {
                    //add your code here to run as part of 1st batch
                } else if (scope[0] == 2){
                    //add your code here to run as part of 2nd batch
                }  else if (scope[0] == 3){
                    //add your code here to run as part of 3rd batch
                }
            } else {
                JobError jobError = new JobError();
                jobError.message = 'Environment Error: Job will only run on dev and automation environment';
                jobError.records = new List<SObject>();
                jobErrors.add(jobError);
            }
        } catch (Exception ex){
            JobError jobError = new JobError();
            jobError.records = new List<SObject>();
            jobError.message = 'Exception: ' + ex.getTypeName() + ': ' + ex.getMessage()  + ' -- ' + ex.getCause();
            jobErrors.add(jobError);
        }
    }
    public void finish(Database.BatchableContext context){
        if (jobCounter<3){
            jobCounter++;
            Database.executeBatch(this, jobCounter);
        }
    }
    public class JobError{
        public String message;
        public List<SObject> records;
    }
    public void setJobError(List<JobError> jobErrors){
        this.jobErrors = jobErrors;
    }
    public static Boolean isSandbox() {
        if ([SELECT IsSandbox FROM Organization LIMIT 1].IsSandbox && ('Dev'.equalsIgnoreCase(CustomSettings.Environment__c) || 'Automation'.equalsIgnoreCase(CustomSettings.Environment__c))){
            return true;
        } else {
            return false;
        }
    }
}

Run the code as

Id batchprocessid = Database.executeBatch(new App_Job_Account_Delete());
