Dear Mr Seleznev,
I assume you tried to install ASE and activated the option that ASE should run the post installation
SQL scripts . This cuases the ASE installer to start ASE after installation an attempt to run the installscripts (via the tool updatease)
After ASE software is updated, some SQL scripts need to be run so that some internal system catalogues are updated to match the updated software (installmaster, installmsg.ebf, installjsdb, ...)
These have to be run with ASE login 'sa' - the ASE system administrator. The 'sa' login , however, is locked during normal opertaions for security reasons (at least in an SAP system).
So have to unlock it before starting the ASE installation when you want to use the installer to update these scripts.
Alternatively call the scripts manually after software update.
Step by step instrcutions for ASE update including a script to perfom these steps can get found in SAP note
