We have quite a few large datasets that are currently spanning multiple 3390-54 volumes. Normally SAS can only address datasets with up to 65535 tracks per volume. As the 3390-54 volumes have almost 1,000,000 tracks available this is becoming very wasteful.
From the reading of
http://support.sas.com/kb/17/038.html I believe that SAS can now access large format datasets (more than 65535 tracks on a single volume).
I have asked our installation guys to upgrade our version of SAS, and PROC OPTIONS is now reporting
NOTE: SAS (r) 9.1 (TS1M3)
...
NOTE: This session is executing on the z/OS V01R07M00 platform.
...
NOTE: SAS 9.1.3 Service Pack 4
However when I attempt to create a DSNTYPE=LARGE dataset I receive message
IEC143I 213-14,IFG0196J,SM0804X0,SAS9,PDB,6920,SPBMXA,...dsn... which is basically saying that SAS is not prepared to open a DSNTYPE=LARGE dataset.
Am I missing something, or does this not yet work?
Thanks
Peter
