The IBM® Data Server Driver for JDBC and SQLJ configuration properties let you set property values that have driver-wide scope. Those settings apply across applications and DataSource instances. You can change the settings without having to change application source code or DataSource characteristics.
property=value
IBM Data Server Driver for JDBC and SQLJ configuration property names are case-sensitive.
You can set configuration properties in the following ways:
For stand-alone Java applications, you can set the configuration properties as Java system properties by specifying -Dproperty=value for each configuration property when you execute the java command.
For stand-alone Java applications, you can set the configuration properties by specifying the -Ddb2.jcc.propertiesFile=path option when you execute the java command.
DB2JccConfiguration.properties can be a stand-alone file, or it can be included in a JAR file.
If the DB2JccConfiguration.properties file is in the ISO 8859-1 (Latin-1) encoding scheme, or is in the Latin-1 encoding scheme with some Unicode-encoded (\udddd) characters, you do not need to do character conversion before the IBM Data Server Driver for JDBC and SQLJ can use the file. If the DB2JccConfiguration.properties file is in some other encoding scheme, you need to use the Java native2ascii converter to convert the contents to Latin-1 or Unicode-encoded characters.
If DB2JccConfiguration.properties is a stand-alone file, the path for DB2JccConfiguration.properties must be in the CLASSPATH concatenation.
If DB2JccConfiguration.properties is in a JAR file, the JAR file must be in the CLASSPATH concatenation.
