Let me explain clear scenario here, actually timer job was showing under job definitions and was working fine but problem raised when i tried to redeploy the updated solution.
First I uninstalled and removed the solution from CA but the Timer Job was showing under Job Definitions even after removing the solution so I used below command to delete the job completely and then I redeployed the updated solution and activated the feature and now the job is missing.
stsadm.exe -o deleteconfigurationobject -id <>
Any help would be greatly appreciated.
Thank you in advance.
