RE: EHP6 Upgrade shadow instance restart
We are performing EHP6 upgrade of our ECC system. Currently, the upgrade is at Preprocessing phase at MAIN_SHDRUN/ACT_UPG, but it stopped, and when we checked in the shadow instance, the job RDDMASGL cancelled after 50000 sec run due to TSV_TNEW_PAGE_ALLOC_FAILED. Prior to starting the upgrade, we updated below parameters with the assumption that the values will be copied when SUM creates the shadow instance, so that we could avoid the stoppage within the MAIN_SHDRUN/ACT_UPG step.
ztta/roll_extension = 3000000000 (3GB)
abap/heap_area_dia = 4000000000 (4GB)
abap/heap_area_nondia = 4000000000 (4GB)
abap/heap_area_total = 4000000000 (4GB)
However, we still hit the error and stoppage, and still need to update the parameters in the shadow instance and restart the shadow instance. Somehow, the parameter value were not copied in the shadow instance parameters.
Can anyone advise how can we avoid this stoppage during the phase MAIN_SHDRUN/ACT_UPG? Is it possible to maintain and restart the shadow instance before the upgrade reaches the MAIN_SHDRUN/ACT_UPG during the pre-processing phase. Is there as note we can follow? Thanks.
We would appreciate your help.
Try setting these values and restart the instance.
ztta/roll_extension = 64000000000
abap/heap_area_total = 5000000000
abap/heap_area_nondia = 5000000000
ztta/roll_area = 10000000
abap/buffersize = 400000000
If possible restart the primary and the shadow instance after cleaning the shared memory segments.
