how can I get by SQL the OS platform on which ASE is running?
It should be possible to get it because if I select the database on
Sybase Central and then File - Properties under platform I see "NT
(IX86) (32-bit)"

What do you mean by ESD 5. we have currently ASE 12.5.4 running how to
apply ESD 5 on 12.5.4

How to Install the license option ASE_ENCRYPTION
Plz describe the steps I have installed ASE 12.5.4

In 12.5.4 I am running this command sp_configure 'enabled encrypted
columns',1
but i m getting this error
