How is ASE involved in this scenario?
This "no language handler installed" message is most commonly seen when someone connects directly to the Backup Server with isql and issues some command like "dump database". In that case the message is expected because Backup Server is an Open Server application and indeed does not have a language handler installed, it communicates directly with ASE using RPC calls only.
Sounds like your application might be connecting to the Backup Server instead of your Open Server application, perhaps some mixup on port numbers in the interfaces file?
