SAP HANA troubleshooting

Logging 

You can find the SAP HANA connector logs at the scratch path within the Delphix Toolkit path on the staging/target environment, located at the following path: 

<toolkit path>/Delphix_COMMON_569f894525f1_761938e53692_host/plugin/hana-staged_1af4cd52-4d56-4e78-a12d-2516a0a2714c/HANA/log_hdbadm/delphixHanaDebug.log

Failure during provisioning 

Depending on where in the provision process failure occurs, and the type of failure, extra steps may be required: 

  • Force Delete of the provision object using the User Interface 

  • The Force Delete option will remove underlying filesystems shared from the Delphix Engine, irrespective of any perceived dependencies on these filesystems. If provisioning fails very early in the process, it is common for the Force Delete option to be the only way to remove an object. This may happen when for example, the wrong password has been entered for the target-side system database user. sap hana troubleshooting

  • In rare cases, manually removing a failed virtual tenant may be required. For example, a tenant with the name “TST”. 

    SELECT * FROM M_DATABASES WHERE DATABASE_NAME=’TST’; ALTER SYSTEM STOP DATABASE TST IMMEDIATE; DROP DATABASE TST DROP BACKUPS;

  • If the Force Delete option cannot unmount the virtual tenant mount points, then the unmount command should be run to remove the stale mount points. 

    umount -lf /mnt/provision/example

Upgrading from Lua to vSDK SAP HANA Plugin 

Datasets created using the Lua version (below 6.0.0) cannot be upgraded to the vSDK version. If you have installed a Lua-based plugin for SAP HANA, we recommend you contact your Delphix Account Team for adopting to the latest version given in the table above.
