  • Sybase is Adaptive Server Enterprise (ASE) prior to 16.0 SP02.

Cause

The NMDA 64-bit package was installed. Since the environment is on Solaris SPARC and the ASE is on version 15.7, 32-bit NMDA should be installed on the client.

Resolution

To determine whether 32/64-bit NMDA software is required depends on whether the database or application is 32-bit or 64-bit, regardless of the operating system being 32/64-bit. 32-bit NMDA is required to support a 32-bit database or application server. 64-bit NMDA to support a 64-bit database or application server. For Sybase ASE releases earlier than 16.0 SP02, 32-bit NMDA supports both 32-bit and 64-bit Sybase ASE on AIX and Solaris SPARC.
