The 'input string' may be defined differently.

The GV for ackMode for the JMS channel was defined as a string "NO_ACKNOWLEDGE". However, the BE Developers Guide gives a reference that ackMode is an Integer and the GV must be an Integer rather than a string.

Environment

All

Resolution

Change the GV to a integer and use the following values for "ackmode":

1  -> AUTO_ACKNOWLEDGE
2  -> CLIENT_ACKNOWLEDGE
3  -> DUPS_OK_ACKNOWLEDGE
23 -> EXPLICIT_CLIENT_ACKNOWLEDGE (TIBCO Proprietary)
24 -> EXPLICIT_CLIENT_DUPS_OK_ACKNOWLEDGE (TIBCO Proprietary)
22 -> NO_ACKNOWLEDGE (TIBCO Proprietary)
 

Issue/Introduction

Use of global variables, unless done carefully, can produce runtime errors.
