Hi, I have a RDS instance, I was used to running maintenance sql statements using pg_cron but for some reason it has stopped working and I can't seem to work out why. I no longer can see any activity in cron.job_run_details and my parameters in my RDS instance stay the same. I have also tried the following `UPDATE cron.job SET nodename = '';` with no luck. Can anyone please advise?

What I am trying to do: * Use Eventbridge to schedule an AWS Batch job to run daily. The problem: * I've created a rule in Eventbridge for a working AWS batch job., but it's is not being kicked off at the scheduled time. The only thing that I can think of that is going wrong is maybe I don't have the correct role type, trust relationship and policy for the rule? Any help provided would be greatly appreciated, thank you! Role Information Role use case type: Allows EC2 instances to call aws services on your behalf Trust Relationships ``` { "Version": "2012-10-17", "Statement": [ { "Effect": "Allow", "Principal": { "Service": "ec2.amazonaws.com" }, "Action": "sts:AssumeRole" }, { "Effect": "Allow", "Principal": { "Service": "events.amazonaws.com" }, "Action": "sts:AssumeRole" } ] } ``` Permissions (related to EventBridge only): AWSBatchServiceEventTargetRole ``` { "Version": "2012-10-17", "Statement": [ { "Effect": "Allow", "Action": [ "batch:SubmitJob" ], "Resource": "*" } ] } ```

I want to enable the notification for mobile phone call alert in AWS. So any job fails, any alert/notification from AWS services (for priority alerts) I want a auto generated phone call to be triggered. I understand that using SNS service, we can enable SMS option. But is there a way to get a phone call as well? 1.If so, what is the AWS native service for that? 2.How to use it and what are the pre-requisites? 3.If not, is there any AWS marketplace product that can be used? 4. Has anyone implemented it and how much reliable it is? Can it be implemented in a production system to alert on production job failures?

Help please, I can't seem to get cron jobs to run. I've always done `crontab -e` to schedule jobs but it doesn't seem to work on my EC2 instance running Ubuntu. I also tried `sudo vi /etc/crontab` and that doens't work either. I tried to schedule the job `/usr/bin/echo "test" > /home/ubuntu/crontest.txt` in `/etc/crontab` as `root` and as `ubuntu` but I never see the test file written. I googled and there are a few StackOverflow posts from people who had trouble with cron. But it seems many of them are able to get it to work after editing the `/etc/crontab` file. Can someone help me figure out why I can't get my jobs to run in cron? Any help or pointers would be greatly appreciated. Thank you.

I am looking for a full-fledged JOB scheduler (that can replace a conventional job scheduler like Control-m,Autosys,rundecl etc) which provides a user interface , has all options/features of a job scheduler, easy to schedule the jobs (adding dependencies, graphical representation of scheduling jobs and can handle complex job scheduling in production). 1. May I know if AWS batch has these features? 2. How about the MWAA scheduler? 3. Can these tools replace a scheduler like (autosys/Control-M etc)? Please note that I am not using AWS components for my application. instead I have installed my application software in EC2 instances and need to run the jobs using scripts. There are very complex requirements/dependencies in our jobs schedule. So I am looking for the best scheduler in AWS.
