For File Upload and Audio Recording questions in Samigo, answers are saved to DB as a blob by default. If you want to save answers to files, you can override this default by adding the following in your sakai.properties file.
Please make sure that Sakai has write privilege to the directory specified in samigo.answerUploadRepositoryPath.
When saveToDB is true, SAM_MEDIA_T.MEDIA must be a blob or equivalent to work. If you're running Oracle and using auto.ddl to create tables, you should check the data type of the "MEDIA" column in the SAM_MEDIA_T table. Hibernate tries to choose the right data type for this field, but has a habit of choosing the wrong one for Oracle. The correct types for each database are:
- HSQLDB --> varbinary
- Oracle --> blob
- MySQL --> longblob
Audio recording questions (since 2.2):
Audio recording questions are turned on by default. You can turn it off by modifying sam/samigo-app/src/webapp/WEB-INF/faceconfig.xml, and changing the showAudio to false.
Audio recording uses the same storage configuration as File Upload questions, so they can be configured to be stored either in DB or files.
Audio recording questions uses an Audio Recording Applet (Based on Sun's Java Sound API) to record. Because the default JRE installation doesn't allow Java to record audio from your computer's sound card, you have to do one of the following:
1. Modify your java.policy file and add the following permissions:
2. Obtain a digital certificate and use it to sign the applet.
Temporary file location for QTI Assessment Import
Currently, by default QTI Assessment Import also uses the com.corejsf.UploadFilter.repositoryPath parameter in web.xml as the location to store a temporary file. These temporary files are removed after the import is completed. com.corejsf.UploadFilter.repositoryPath is set to /tmp by default. This again can be overridden in sakai.properties the same way as in File Upload/Audio recording questions. Please make sure that Sakai has write privilege to this directory.
Conversion from 2.2.x to 2.3
If you are upgrading from Samigo 2.2.x to 2.3, after you finish running the conversion script, please be sure to turn off autoddl by setting autoddl=false in your sakai.properties file. There is a known issue with autoddl=true which causes duplicate indexes to be created.
