SAP 4.7/6.20 won't start

[Former Member]

Hello,

When I try to start SAP I get a SQL error saying "DB-Connect failed, return code 000256". Does anyone know what could cause this error. The system has a fresh install of 4.7. The database has been restored from our PRD system which was upgraded from 4.6B to 4.7. I had to change the environment variable, MSSQL_SCHEMA from sbx to "dbo" in order to install the license key (Note 534765). Thanks in advance.

i am not sure

however this message seems no to be of SQL server

but from client ODBC

because there is no any messages about connection on SQL-server behalf,

but error messages in SAP application

so the SAP system can not find databasa

that is what i think

after fixing it i have working system

I have got the same error today

... finally i have realized that host name/database name

were not correct in my client configuration files

Note 551915 did the trick.
