In which directory are SAP HANA temporary files located?

The directory where SAP HANA temporary files are placed is indeed /var/tmp/hdb. This directory is specifically designated for storing temporary files generated by the SAP HANA database system during its operation. Temporary files are essential for various processes, such as storing intermediate results during query execution or managing log files that are not needed permanently.

Understanding the purpose of this directory helps clarify the overall structure and organization of files within the SAP HANA environment. It's essential for effective system maintenance and performance monitoring, as temporary files can influence both the system's efficiency and available disk space.

Other directories mentioned have different functionalities. For instance, /var/lib/hdb/SID typically contains the main data files for the SAP HANA database related to a specific system identifier, and /tmp/hana/logs is used for logging purposes. The directory /opt/hana/temp is likely used for other temporary purposes but not specifically for SAP HANA's operational temporary files, which solidifies the importance of /var/tmp/hdb as the correct location.
