Transient volume configuration components

In a two-tier environment the value used for the Transient_Volume_RootDir preference is always overridden by a user-specific directory; the values set for any transient volume-related preferences or environment variables are ignored. Caution Do not define the directory path as a UNC path, for example, \server\shared-transient-folder. Use a direct path location. This requirement is because some ZIP archive utilities do not accept UNC paths, resulting in failed exports to Microsoft Excel or Word. If the TC_TMP_DIR environment variable is set, the value used for the Transient_Volume_RootDir preference is: ${TC_TMP_DIR}/${USER}2TierTransientVolume on Linux TC_TMP_DIR%%USERNAME%2TierTransientVolume on Windows If the TC_TMP_DIR environment variable is not set, the value used for the Transient_Volume_RootDir preference is: /tmp/${USER}2TierTransientVolume on Linux c:\temp%USERNAME%2TierTransientVolume on Windows In a four-tier environment, three elements control transient volumes: The site ID defines the database ID for the system. The Transient_Volume_RootDir preference is a multi-value variable used to provide Linux and Windows path name of the transient volume on the server. When set as a preference, the values must be valid for all machines of each platform type. When set as an environment variable (which overrides any preference values) only a single platform path can be specified. The preference is designed to accept multi-values to support multiple platforms. However, if you set this preference with identical values, the following error message appears: Copy Duplicate transientvolume configuration elements were found for attribute id with value attribute_value If you are using only one platform, you can delete the other value to ensure you do not receive this error message. The Transient_Volume_Installation_Location preference specifies the node name of the transient volume. It is a location-based logical identifier and is generally set to the host name of the local machine by the TC_DATA\tc_profilevars script. The transient volume location is read/write/verify checked during TcServer startup. The location value and any warning messages about the transient volumes are printed to the TcServer system log for diagnostic purposes.
