To launch DbMaintain from the command line, you have to create a properties file dbmaintain.properties that configures the location of your scripts and the target database, for example:
database.driverClassName=org.hsqldb.jdbcDriver database.url=jdbc:hsqldb:mem:testdb database.userName=sa database.password= # Comma-separated list of all database schemas used. database.schemaNames=PUBLIC
Make sure you've correctly set JAVA_HOME to your JRE or J2SDK home directory, and set DBMAINTAIN_HOME to the installation directory of dbmaintain. Set DBMAINTAIN_JDBC_DRIVER to the jar file that contains the necessary JDBC driver for your DBMS, or edit the file bin/setJdbcDriver.sh (or .bat) to set JDBC_DRIVER to the correct value. Then execute following command (Replace .sh by .bat if you're using windows)
/path/to/dbmaintain/dbmaintain.sh updateDatabase path/to/scriptFolderOrArchive
To use a different config file than dbmaintain.properties, add the parameter -f followed by the config file name. System properties can also be used to configure the command line.
