Commands for Processing Without Module Definition Files
The SQLJ translator program, sqlj.tools.Sqlj, is a Java program that
automatically invokes translation, Java compilation, and customization of an SQLJ
program, depending on the options that you pass to it. See the SQLJ Translator
Command Line on page 5-10 and Using Command-Line Options on page 5-6.
By default, the processing of an SQLJ source file follows these steps when you run the
SQLJ translator program:
1. Translation. See Command for Translation on page 5-2.
2. Java compilation. See Commands for Java Compilation on page 5-2.
3. Customization. See Command for Customization on page 5-3.
For a diagram of these steps, see Figure 1-1 on page 1-10.
To invoke SQL compilation, you must run the mxCompileUserModule utility after you
run the SQLJ translator program, sqlj.tools.Sqlj. For more information, see
Command for SQL Compilation by mxCompileUserModule on page 5-3.
Command for Translation
If you specify a .sqlj file (SQLJ source file) on the SQLJ command line,
sqlj.tools.Sqlj by default invokes translation, Java compilation, and
customization of the SQLJ program. For example, issue this OSS command to initiate
translation:
java sqlj.tools.Sqlj MyProg.sqlj
You can disable customization with the -profile option and disable Java compilation
with the -compile option.
For more information, see Translation on page 1-11 and Options for the SQLJ
Translator on page 5-21.
Commands for Java Compilation
If you specify a .java file (Java source file) on the SQLJ command line,
sqlj.tools.Sqlj performs Java compilation on the file. For example, issue this
OSS command to initiate Java compilation:
java sqlj.tools.Sqlj MyProg.java
For more information, see Compilation by the Java Compiler on page 1-12 and Options
for the Java Compiler on page 5-24.
Caution. If you do not run mxCompileUserModule, you will not generate module files, and
the program will either run dynamically or return an SQL exception indicating that the module is
missing or corrupted. For more information, see SQL/MX Compiler Errors
on page 4-5.
Note. It is faster to translate multiple source files simultaneously rather than translating
individual source files one at a time.
