Unexpected Weird bugs in SAP PA 2.2(Expert Mode)

Hi

 

I am trying to run auto classification algorithm with the data set having around 4,50,000 rows with 50 columns. I am using 8 GB machine.

 

Let me list down the error i faced up until now for the same dataset:

 

BUG1 : First time when I tried running the model with around 30 columns as input and 1 Target Variable. Below attached error popped up. Despite the fact I have allocated 4GB virtual memory for the tool using .ini file

 

[Sybase][ODBC Driver][Sybase IQ]You have run out of space in IQ_SYSTEM_MAIN DBSpace.

-- (s_blockmap.cxx 4566)

undefined

 

However after the multiple restarts of the tool and doing trial runs, the model run successfully took about 12 mins.

I got the output, did some visual analysis and created a story board and saved the document.

 

BUG2: Ok after sometime when I tried reopening the document, a new error pops up:

magically the story board was there but in the predict tab I can't see the model  anymore.Blank predict tab, no algorithm mapping nothing. It happened earlier also I posted the same issue on scn previously but no concrete solution yet .

BUG3: Ok I thought may be data is too large, I deleted few junk columns and the dataset size got reduce to 173 MB from 234 MB. And I applied the Auto Classification algorithm. The model ran successfully, and now when I am trying to apply Model Statistics component to the model,  a new error pops up

and this above error didn't came first time when I saved the document earlier which got corrupted.

 

I really don't get it whats the issue. My more focus and time is taken away on fixing such issues, rather than working on the algorithm.

Does anyone has any suggestion on how to handle such issues or why its happening like that?

 

Regards

Ranajay
