5.6.3 Java applications
Table 5-9 lists the Java applications. All Java applications are packaged into the
Java archive itso.jar. When starting a Java application, we have to make sure that
all used classes are available to the runtime. This is done by setting up the
classpath. We must therefore add itso.jar to the classpath. The DDLExecuter and
the MigrateExecuter connect to DB2 from Java, so for these applications we add
also add db2jcc.jar and db2jcc_license_cu.jar to the classpath.
The Java applications will exit with one of the following codes:
0: If execution was successful.
1: If wrong number of arguments were passed to the application.
2: If any error occurred during execution.
