• Message text: Modif. refusée : aucun processus de débogage exclusif disponible actuel.

Quelle est la cause de ce problème?

The Debugger was unable to switch from "Non-Exclusive Mode" to
"Exclusive Mode". The reason for this is that all available work
processes were already in use with other debugging sessions.

Le système émet un message d'erreur et ne vous permettra pas de poursuivre cette transaction tant que l'erreur n'est pas résolue.

Restrictions in "Non-Exclusive Mode":
For every Debugger interaction, a database commit must be triggered.
As a result:
- You cannot debug between "SELECT ... ENDSELECT" (short dump in
Debugger)
- If the debugging session is cancelled, the database content can become
inconsistent.
Since there can be no database inconsistencies in production systems,
the "Non-Exclusive Mode" is not possible there. Instead of starting the
Debugger in "Non-Exclusive Mode", the system triggers the short dump
"DEBUGGING_IMPOSSIBLE".
The number of work processes exclusively available for debugging in
production systems is defined in the profile parameter for the number of
dialog work processes as follows: "rdisp/wp_no_dia / 2"
In non-production systems, this number is set using the profile
parameter "rdisp/wpdbug_max_no". It is recommended that
"rdisp/wpdbug_max_no" is roughly equal to "rdisp/wp_no_dia / 2".
On the other hand, the default value "rdisp/wpdbug_max_no = 1"
is almost always too low.

Réponse du système

Comment corriger cette erreur?

Keep trying to activate the "Exclusive Mode" ("Debugger -> Exclusive
Debugging Mode On"). In the meantime, a work process may have become
free for exclusive use by the Debugger.
