Library assignment for journal receivers
When you create a journal receiver, you specify a qualified name that includes the library for the receiver. The library must exist before you create the journal receiver.
You can assign a library from either the New Journal dialog in System i® Navigator or with the Create Journal Receiver (CRTJRNRCV) command.
Your journals and journal receivers can be in different libraries. If they are, you must ensure that the library that will contain the journal receivers is on the system before restoring the journal. Ensuring this will also ensure that the journal receiver is created in the desired library, since a journal receiver is created when the journal is restored. Only the library needs to be on the system, not the journal receivers in that library. Also, you will want to save the library with the journal receivers last (after all journaled objects have been saved) to ensure that all the journal entries recording the object saves will be on media.
Refer to the Correct order for restoration of journaled objects link below for additional considerations.
