You receive this error: **Cannot start system. Start instance 00 on host '`hxehost.localdomain.com`' failed. FAIL: process `hdbdaemon` HDB Daemon not running.** **Solution:** Use `zypper` to check the `util-linux`, `util-linux-systemd` and `uuidd` packages to make sure they are at these versions: `zypper info util-linux util-linux-systemd uuidd` The results need to show that you have at least the following versions installed: `util-linux`: `util-linux-2.25-22.1` `uuidd` : `uuidd-2.25-22` `util-linux-systemd`: 2.25-22.1 If you are missing any of the packages, or if the versions are outdated, install them using the `zypper` install command. Check that socket activation is enabled and started. In a shell enter: `systemctl` status `uuidd.socket` If the status is inactive, start socket activation: `systemctl` start `uuidd.socket` ### SAP HANA XS Applications Run Error **Issue:** You are trying to run a SAP HANA service on your SAP HANA 2.0, express edition installation and are receiving an error. **Solution:** Log in to your SAP HANA 2.0, express edition installation as `hxeadm`. ``` sudo su -l adm ``` Check which services are enabled on your machine: ``` xs apps ``` This operation may take 1-2 minutes to return the list of apps.

Run `xs apps` again to see if the app has started and that under `instances` the app shows `1/1`. ### Download Manager Shows Error **Issue:** You have received the following error: `Failed to concatenate downloaded files` You are downloading packages using the Download Manager. The Status area and Progress Detail area show the error `Failed to concatenate downloaded files`. **Solution:** Check the log file for details. The log file is in the Temp directory: Linux: **`/tmp/hxedm[yymmdd].log`** Windows: **`%TEMP%\hxedm_[yymmdd].log`** If the log indicates a simple issue such as lack of disk space or file permissions, fix the problem and download again. If the problem is less obvious, do the following: Go to the **Save directory**. Delete all downloaded files, including incomplete download files. Download again. or Change the **Save directory**. Download again. ### Locate Download Manager Log File **Issue:** You are downloading packages using the Download Manager when you terminate Download Manager before download completes, or Download Manager quits unexpectedly. **Solution:** Check the log file for details. The log file is in the Temp directory: Linux: **`/tmp/hxedm[yymmdd].log`** Windows: **`%TEMP%\hxedm_[yymmdd].log`** ### Memory Limit Exceeded - No Additional Local Capacity **Issue:** You have exceeded the 32GB memory limit of SAP HANA, express edition. **Solution:** Consider migrating to SAP HANA Cloud.
