HDB - Some services are not started

Hello,

Finally I was able to update AWS hana system to Rev 56 from Rev 48. After installing new hana client & studio of rev 56, I tried to add system.

First I used elastic IP as Hostname & used SYSTEM & default password as database user & got below message.

"The system is not reachable, the login data could not be considered"

So I put public DNS (ec2-XX-XX-XX-XXX.compute-1.amazonaws.com) as hostname & used SYSTEM & default password as database user & able to connect successfully.

But I am getting below "Yellow" message in HDB added system. "some services are not started".

With this message when I checked forum I found to check below system properties:

First thing I found that database memory is a problem. How do I decrease this imdbhdb used memory ?? Btw I am using m2.2xlarge in AWS.

Clik here to view.

Second thing - in a same system view: I don't see any services running. How do I start those services ??

Clik here to view.

THANKS,
