The VM IUCV communication codes are usually displayed as returned to the DB2 Server for VM system. In some cases, they are translated by the database manager. These codes are displayed by the database manager and the Resource Adapter virtual machines.
The message ARI0504I is issued by the Resource Adapter and displays the request code, return code, and reason code. If the reason code = 06 or 07 with a return code of 04, accompanying messages will be issued by the DB2 Server for VM virtual machine. The accompanying messages must be considered to determine the condition that existed and the action to be taken.
The following is a list of the reason codes, return codes, and their meanings as contained in message ARI0504I. The list is presented in four parts:
