Hi Brad,
Banging my head against a brick wall here. Constructing an ASE 12.5.4 environment on a server 2012 VM (likely not supported) is proving challenging. It half works in XP compatibility mode but java is not happy.... To get a 12.5.4 staging environment working properly I would need to build a windows server 2003 VM and a windows XP client, get the ODBC drivers working properly etc. and test it. Software of this age is extremely hard to track down and license (particularly without an up to date support agreement with SAP)...
I am working on an option that is looking positive so far, though it's the last thing I wanted to do.... namely migrate the data from Sybase 11.9.2 to SQL server 2012. The SQL Server migration tool does support this early version of Sybase, and fortunately the 9 databases I need to convert are not too big or too complex so i'm cautiously optimistic. Analysis and dry-runs to date suggests this may be the least painful solution. Keen to rip the data out of this ancient environment before it dies.
Thanks for you help. This just demonstrates the folly of running a production system in a 16 year old environment; all good fun.
