ztta/roll_extension_dia: EM Quota for Dialog Processes

Use

This parameter specifies the maximum SAP Extended Memory that can be used for dialog work processes.

Integration

Earlier, both non-dialog processes (BTC, UPD, UP2, SPO, etc.) and dialog processes were handled the same regarding the allocation of extended memory. You could not allocate separate EM quotas to dialog users and batch users. The quota was determined by ztta/roll_extension and was valid for all work process types.

Only the heap memory had a separate quota (compare abap/heap_area_dia and abap/heap_area_nondia).

To ensure compatibility with the earlier implementation, the following rules apply:

·        If ztta/roll_extension_dia or ztta/roll_extension_nondia are not set (DEFAULT.PFL or instance profile), the value in ztta/roll_extension (old procedure) applies for ALL work process types.

·        If, on the other hand, ztta/roll_extension_(non)dia is set, the value in ztta/roll_extension is overwritten for the work process type in question.

Activities

The value is specified in bytes.

The minimum is 20000000 (20 MB); the maximum is 64000000000 (64GB, for 64 bit platforms).

The default setting is the value of ztta/roll_extension.
