When you install DirectConnect 12.6.1 and Adaptive Server Enterprise (ASE) 15.0, Sybase strongly recommends that you install the Mainframe Connect DirectConnect for z/OS Option 12.6.1 (including DirectConnect Manager) in its own product directory.
ASE 15.0 includes new major versions of ASE and many of the supporting components. All other current Sybase products (for example, Replication Server® 12.6 or Enterprise Connect™ Data Access 12.6.1) contain earlier versions of those same components. Installing ASE 15.0 into the same directory with existing products should not impact the existing products. However, installing other products after ASE 15.0 may result in one or more products not working correctly. Sybase recommends that you install ASE 15.0 into its own directory, if possible. Where this is not practical (for example, on Windows) and when other products must be installed into the same directory, ASE 15.0 should be installed last.
