Start Hana/Frontend Server during Boot on AWS

Hi all,

we have a Linux instance which is hosted on AWS. On this machine we installed Hana with the XSA addon. Moreover, on the same machine an ABAP Front-end server is installed. We deployed custom SAPUI5 applications to the ABAP repository that are accessible through the Fiori Launchpad. The applications access the backend system via ODATA which is developed with Java on Hana XSA.

Now we shutdown our AWS instance everyday to save costs. I wrote a little script which I added to the after.local and halt.local file so that the HANA and Frontend server is started/stopped automatically. The script looks likes follow:

after.local:

su - <HANASID>adm –c “/usr/sap/<HANASID>/HDB00/HDB start”
su - <ABAPSID>adm –c “/usr/sap/<ABAPSID>/SYS/exe/uc/linuxx86_64/startsap r3”

halt.local

su - <ABAPSID>adm –c “/usr/sap/<ABAPSID>/SYS/exe/uc/linuxx86_64/stopsap r3”
su - <HANASID>adm –c “/usr/sap/<HANASID>/HDB00/HDB stop”

The script works fine. However, the Hana database not start the XSA components. At every boot process randomily one service such as xscontroller/xsexecagent/xsuaaserver failed to start. In the log files i found this:

When I not using the startup script and manually execute the script when the AWS instance is up it works fine.

Somebody why this is not working during the bootstrap phase on AWS?

Best regards,
