Hi Vamsee,
Try this,
I assume you have created a Schedulable class. You can schedule it using the system.schedule command:
Step 1. In developer Console select debug menu and in that menu Open execute Anonymous Window
Step 2. 
System.schedule('Scheduled Job 1', '0 0 11/12 * * ?', new yourclassName());
Hope this will help you. Please mark the answer as a solution.

Regards,
Akshay

Hi Vamsee,
To Stop Scheduled job :
Navigate to Setup => (In Quick Find box) Scheduled Jobs
Now you have the list of scheduled jobs. Delete those which you don't want to execute.
To schedule new job which runs twice a day  
String sch = '0 0 11/12 * * ?';
//0 0 {time to schedule}/{hours until repeat} * * ?
Example To run twice a day, i.e 8 AM and 8 PM 
String cron = '0 00 08,20 * * ?';
//Runs at 0800h and at 2000h every day
I hope it will help you.

Akshay

HI Vamsee,

Please use this in the developer console Anonymous window. You will use something like below code.

For the running your Schedule class. Please fill your Schedule class name in the place of  Schedule_CreateNewRecords . 
Schedule_CreateNewRecords  batchSch=new Schedule_CreateNewRecords ();
String sch='0 1 0 * * ?';
//System.schedule(String jobName, String cronExp, APEX_OBJECT schedulable);
System.schedule('Batch Schedule', sch , batchSch);

Till if you have not created schedule class.I have attached the code below.

Schedule class name- In the place of batchclassname. please fill your Batch class name.  
global class Schedule_CreateNewRecords implements Schedulable{
    global static void execute(SchedulableContext SC){
        //this simply runs the batch from step 2
        Batchclassname CNR = new Batchclassname();
        ID idBatch = Database.executeBatch(CNR); 
    }
}
Please mark my answer as a solution if it was helpful so it is available to others as a proper solution.

HI,
  
Schedule_CreateNewRecords  batchSch=new Schedule_CreateNewRecords ();
String sch='0 0 11,12 *  *?';
//System.schedule(String jobName, String cronExp, APEX_OBJECT schedulable);
System.schedule('Batch Schedule', sch , batchSch);

Please use this in developer console Anonymous window.
