According to http://docs.sun.com/app/docs/doc/821-1751/gitzw, restart will be
required if the following are modified for a JDBC connection pool:
JDBC driver vendor-specific properties
I changed the first 3 entries in Admin Console for Derby connection pool and
restart was not indicated as required by neither Admin Console nor CLI
(list-domains). I checked domain.xml and the entries were there. The vendor
specific properties are listed under Additional Properties and making changes to
those does not trigger restart required either.
Hence it looks like documentation should be changed, cc'ing Jagadish and Anissa
to be sure.
