Special Considerations for Java External Procedures
Java external procedures can only be run in EXECUTE PROTECTED mode. If you specify EXECUTE NOT PROTECTED for a Java procedure, the request aborts and returns an error message to the requestor.
For Java external procedures, the COMPILE option operates identically to external procedures written in C or C++ with the exception that the extension the JAR file references in the Java external procedure EXTERNAL NAME clause (see “CREATE PROCEDURE (External Form)/ REPLACE PROCEDURE (External Form)” on page 422) is redistributed to all affected nodes on the system. Redistribution is useful when a JAR file is missing on a given node.
The ONLY clause on the COMPILE option for external procedures written in Java generates preamble files, but does not redistribute their associated JAR file.
