If you try to manage your HANA certificates via SQL you might want to set the “OWN CERTIFICATE” where you come across the following error in your SQL Commandline: 1 2 Could not execute 'ALTER PSE HANA\_X509 SET OWN CERTIFICATE '-----BEGIN RSA PRIVATE KEY----- ...' SAP DBTech JDBC: [5634]: Certificate definition inconsistent Looking at the indexserver trace you will find: 1 2 [113263]{213394}[35/-1] 2016-05-24 15:44:56.384001 e Crypto check\_pse\_store.cc(00178) : Trying to add invalid certificate as part of own certificate PEM: exception 1: no....
