Subject [jira] [Commented] (DERBY-5442) Create documentation for restrictive file permissions feature
Date Tue, 08 May 2012 13:09:49 GMT

    [ https://issues.apache.org/jira/browse/DERBY-5442?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13270445#comment-13270445

Knut Anders Hatlen commented on DERBY-5442:

> Can the derby.storage.useDefaultFilePermissions property be set on a database or only

Only as a system property or as an application property in derby.properties, if I read the
code correctly.

> Also, if we say that it's dynamic but it's not a good idea to set it dynamically, what
is the explanation for why it's not a good idea?

Since the property will only affect the permissions of files created after the property was
set, setting it dynamically will make some database files restricted and others not restricted.
One will have to shut down the database and run operating system commands (like chmod) to
change the permissions of already created files. Although it's not a problem in itself that
the permissions are not consistent, users will typically want either all files in the database
or no files to be restricted, not a mix of restricted/unrestricted files.
