Setting the project cache file’s save mode
By default, the cache file is saved after the survey is completed. Cache files are important for synchronization. As such, it is important to ensure that the cache file is not missing data that could be lost in cases such as server crashes, power losses, and so on.
UNICOM Intelligence Interviewer provides the option of saving the cache file after each question is asked. This option is named WriteCacheAfterEachQuestion and can be opened or closed by modifying the IPlayerConsole.exe.config configuration file.
Note The option is disabled by default as it may negatively affect overall system performance.
Enabling the WriteCacheAfterEachQuestion option
1 Exit the UNICOM Intelligence Interviewer application.
2 Use Notepad, or a similar text editor, to open the IPlayerConsole.exe.config file, which is in:
[INSTALL_FOLDER]\IBM\SPSS\<version>\Interviewer\
3 Change the WriteCacheAfterEachQuestion value to true. For example:
<appSettings>
...
<add key="WriteCacheAfterEachQuestion" value="true"/>
</appSettings>
4 Save the IPlayerConsole.exe.config file, and then restart UNICOM Intelligence Interviewer.
Disabling the WriteCacheAfterEachQuestion option
1 Exit the UNICOM Intelligence Interviewer application.
2 In the IPlayerConsole.exe.config file, change the WriteCacheAfterEachQuestion value to false. For example:
<appSettings>
...
<add key="WriteCacheAfterEachQuestion" value="false"/>
</appSettings>
3 Save the IPlayerConsole.exe.config file, and then restart UNICOM Intelligence Interviewer.
