SUM tool unable to detect auto extend and space in DB

Question

Hi SAP,
We have started update on our ECC Dev system using SUM10 SP09 and it showed up an error during extraction phase stating auto extend is not enabled and also insufficient space in DB.
hnpclecd:ecdadm 62> cat SYBSPACE.LOG
SCRIPT SYBSPACE
=================
auto extend feature is not set
Msg 3606, Level 16, State 0:
Server 'ECD', Line 41:
Arithmetic overflow occurred.
======================================================
We have enabled auto extend mode with below commands :
exec sp_dbextend 'set', 'device', ECD_data_001, '10m', '512m'
exec sp_dbextend 'set', 'device', ECD_data_002, '10m', '512m'
exec sp_dbextend 'set', 'device', ECD_log_001, '10m', '512m'
exec sp_dbextend 'set', 'device', ECD_log_002, '10m', '512m'
exec sp_dbextend 'set', 'device', ECD_log_003, '10m', '512m'
exec sp_dbextend 'modify', 'device', 'default', 'growby', '3m'
exec sp_dbextend 'set', 'database', ECD, 'default', '5m'
exec sp_dbextend 'set', 'database', ECD, 'logsegment', '4m', '100m'
exec sp_dbextend 'list', 'database', ECD
And sp_dbextend list also returns appropriate values.
1> exec sp_dbextend 'list', 'device', "ECD%"
2> go

         growby                       10m
         enabled
(return status = 0)

And sp_helpdb also shows there is enough space available:

But still we are unable to proceed. Please let us know if correct procedure has been followed for auto extend.
Please help urgently!!!

Answer 1

The image shows a database/panic error and no sign of an actual number indicating space available in the database.  Then there's this:
hnpclecd:ecdadm 62> cat SYBSPACE.LOG
SCRIPT SYBSPACE
=================
auto extend feature is not set
Msg 3606, Level 16, State 0:
Server 'ECD', Line 41:
Arithmetic overflow occurred.
======================================================             
I'm guessing ...
The SYBSPACE script is suppose to generate some numbers indicating space usage for the database in question.
But the SYBSPACE script runs into an error so it fails to generate the space usage numbers that SUM is looking for.
SUM is proceeding as if the lack of space usage numbers is an indication of no free space in the database, as opposed to aborting the entire process because of the SYBSPACE error.
Fix the code that's generating the error in the SYBSPACE script and you'll probably find that SUM is then able to accurately assess the state of your database.
The code that's generating the error (3606, arithmetic overflow) definitely needs to be fixed by SAP (ie, open a tech support case with SAP) but in the meantime if you've got access to the SYBSPACE script, and you understand T-SQL, you could probably fix the SYBSPACE script so that you can continue with your SUM operation.
