Parameter
ztta/roll_extension_dia

Short text
Quota in extended memory for dialog processes

Parameter description
This parameter specifies the maximum amount of extended memory to beoccupied by dialog work processes. Previously, non-dialog processes(BTC, UPD, UP2, SPO, etc.) and dialog processes were handled in the sameway. You could not allocate separate EM quotas for dialog users andbackground processing users.
The new profile parameters ztta/roll_extension_dia andztta/roll_extension_nondia allowyou to set EM quotas that differentiate between the work process types.
To remain compatible with the "old"
ztta/roll_extension parameter, the following rule applies:
If ztta/roll_extension_dia or ztta/roll_extension_nondia are not set(DEFAULT.PFL or instance profile), the value in ztta/roll_extension (oldprocedure) applies for ALL work process types. If, on the other hand,ztta/roll_extension_(non)dia is set, the value inztta/roll_extension is overwritten for thework process type in question.
