HANA Lifecycle Manager shows blank page

 

We had an issue where the HANA application lifecycle manager shows the login page but after sucessfully authenticating just shows a blank page.

The issue was with the HANA LCM delivery unit was not activated properly and we had to deploy them again .

 

The following query shows if any objects were invalid on HANA

select * from “_SYS_REPO”.”ACTIVE_OBJECT” where object_status > 0;

and this query shows the version and date of the deployment for  LM

select * from “_SYS_REPO”.”DELIVERY_UNITS” where delivery_unit = ‘HANA_XS_LM’;

 

the following step with redeploy all teh auto content DU’s
As <sid>adm user, log on to the server and deploy all auto content DUs on the system database by executing the following command:
/usr/sap/<SID>/SYS/global/hdb/install/bin/hdbupdrep –content_directory=/usr/sap/<SID>/SYS/global/hdb/auto_content

 

and in our case we just had to redeploy the LM delivery unit via studio

File > Import > Import Source: “Delivery Unit” > Choose the right target system > Select from “server” file: “/usr/sap/<SID>/SYS/global/hdb/auto_content/HANA_XS_LM.tgz” > Finish.
