SAP HANA FAQs

Environment authentication using a key pair 

Perform the following steps to use a generated key pair when adding a new environment to the Delphix Continuous Data Engine: 

  1. When following the Add Environment wizard and on the Environment Settings page, select Public Key for the Login Type.

  2. Click View Public Key. 

  3. Copy the public key that is displayed and append it to the end of your ~/.ssh/authorized_keys file. If this file does not exist, you must create it.  

    1. Run chmod 600 ~/.ssh/authorized_keys to allow only the file's owner to read and write to it (make sure the file is owned by you).

    2. Run chmod 755 ~ to restrict access to your home directory so that no other may write to it.

    3. Run chmod 700 ~/.ssh so that others cannot write to it. The ~/.ssh  is not writable by group or others. Otherwise, authentication will fail. 

Troubleshooting dSource failure involving encrypted backups

1. Error while performing recovery during dSource creation

Flow Impacted: dSource creation

Error Message: 

448: recovery could not be completed: [110126] Backup rootkey e3f36c2155a09f5a9a5fb53bcba33ac880fae888d2c5bf181378569cd71c3da2 is required for decryption of backup files, but not found in key store. Please make sure you have provided the necessary keys before recovery., [301103] No root key matching hash=e3f36c2155a09f5a9a5fb53bcba33ac880fae888d2c5bf181378569cd71c3da2 SQLSTATE: HY000
