DbTest database information tool

DbTest is a simple tool for dumping database metadata. It can be used to examine attributes which a particular database vendor supports such as transaction support, and table column sizes. DbTest reads the properties/rdbm.properties file to obtain the database connection information.

DbTest can be invoked from the uPortal build directory using ant by simply typing:

ant dbtest

It will produce output similar to the following (this is for a PostgreSQL database):

% ant dbtest
Buildfile: build.xml

prepare:

compile:
