Hi Team,
We are currenlty performing a time based reduction scenario to build
our pre-production system from a staging server(copy of production).
We are stuck up with Issue where updation for VBUK_2 has been taking
longtime .This step started on 26th january and it is still running (50
hours ) but this doesnt seem to complete now
We have set all the required parameters for increasing the performace of fill header as below
We also have created an index ZM1 to include below values for VBFA as per note 1256679
MANDT
VBELN
VBELV
POSNV
No change was observerd after above activity.Attached image has the parameter settings
Please suggest if there is any other parameter/settign that needs to be done to improve performance
TDMS version 4.0 SP3
Table:VBUK
Total No of entries: 45,809,350
Table:VBFA
Total No of entries: 282495,909
Source:ECC6 EHP4
Reciever:ECC6 EHP4
Note:Same refresh activity was performed last year when source DB size was 4.6 TB now it is 5.2 TB
last time it completed in 16 hrs but now it has been running from past 4 days still not yet completed
It seems to be that data has been split into 5549 portions and job is filling data for each partition .But once the portion is imported it is again scanning the rest of the entries in sequence and once it reaches next portion(1213) then the import is being completed.We cancelled the above run as well.For each portion it was taking 10 minutes .After updating DB stats for cluster table it improved a bit but not sufficient.If I calculate based on above portions and time taken it is still needing 95 hrs approx. to complete the fill header .
So we changed Settings present for FILL VBUK_2.Previosusly there were different settings we changed P_PARA to 8 from4 and P_SELECT=R from FULL.
Please suggest
Regards,
Murali
