Need more disc space for a simulation

Piers — Mon, 26 Apr 2021 12:08:01 GMT

Hello,

I am running a numerical simulation with PROC SIMNORM which is trying to create a large data set that has 6 columns as output. The input is a dataset with 26,040,000 rows.

PROC SIMNORM appears to be handling it well until it runs out of work space. So, I would like to know how to redirect SAS where it writes the temporary work files.

Basically, I have 1.4Tb available on another disc (F: drive), and would like to try to use this instead of the default which is on the C: drive.

I do have admin rights.

Help very gratefully received

libname x v9 'd:\temp';
options user=x ;
proc .........

Goodness me - so straightforward

I just tested the first step in my script, and the first data set was stored in the new location just fine (I renamed the library to be called PLCTEMP).

However, in the explorer view, I notice that if I try to renew or delete the datafile it wont let me.

It gives the following:

ERROR: A lock is not available for PLCTEMP.RAW.DATA

Presumably this has to do with write/read permission.

Is this solvable?

Best, and very many thanks so far

It is write/read permission problem. Can you use another folder to assign a LIBNAME ?

I could try drive G: which also has more space than C:

Drive F: has been assigned to be my google drive and I has had odd problems with read/write access for SAS using this drve before, for reasons that are very opaque

Could you try batch process ?
Direct your WORK into G: (g:\temp\)
