nuodb-migrator Properties File

There are two types of files used by the nuodb-migrator tool:

  • Configuration File (nuodb-migrator.properties)

  • log4j properties File (log4j.properties)

Depending on the method of installation, the location of these files is as follows:

Installation method Location of configuration files

NuoDB Client Package Installation

<NuoDB Client package home dir>/conf

GitHub Source Build

$NUODB_MIGRATOR_DIR/migration-tools/assembly/target/nuodb-migrator/conf

The property that sets JDBC connection trace file logging is turned off by default, for performance reasons. This option controls logging the DDL SQL statements that execute during nuodb-migrator load command processing. If the option is turned on, the performance of nuodb-migrator load will be negative impacted.

To log these DDL SQL statements, comment out the following line in the properties file by adding a # character at the beginning of the line:

log4j properties File
log4j.logger.com.nuodb.migrator.jdbc.connection=none

This will log all DDL SQL statements generated to a file named nuodb-migrator.log. An environment variable, NUODB_MIGRATOR_LOGDIR, should be set to define the location of this file. If the environment variable is not set, the file location will default to the system’s temporary directory.
