I created a new SQL-Anywhere 17 database on a machine on which OEM Version is installed using the following command: dbinit.exe" -z "UTF8BIN" -zn "UCA" -i -dba dba,123456 -pd -t mydb.log mydb.db

When I try to change the password of dba on the OEM machine, I get Authentication violation!!! grant connect to "dba" identified by "12345678"

I copy the same database (which was created on an OEM machine) to another developer machine, then everything works fine (no authentication violation).

Could you please tell what happens here? At the end I need to change the password on the OEM machine.

For the OEM version of sql anywhere you need the corresponding authentication settings.


So basically, beside the login credentials, you will also need to: - Set the OEM "key" in the database - Provide the connection authentication

Step 1:


Step 2:

connection_authentication='company =

If you don't have this info from the OEM Database, then for development purposes just use the developper edition of sql anywhere

Do I need the signature even with EXEs of SQL-Anywhere? I am connecting to the DB using dbisql.exe

To quote the docs:

All the database tools included with SQL Anywhere, including Sybase Central, Interactive SQL, and the utilities, such as dbbackup, are self-authenticating. They are unrestricted in their operations against any authenticated database. If the database itself is not authenticated, the tools act in a restricted, read-only fashion.

So I would assume the database itself is not authenticated here? Typically, you would use an authenticate.sql script file in the setup of the according machine.

This means that on an OEM-Version I have restricted connection to a not-authenticated database when I use dbisql.exe, this is somehow weird.

> on an OEM-Version

If you don't want OEM restrictions, don't use an OEM copy of the software... it's not even a little bit weird: with lower prices comes higher restrictions :)

The database_authentication must be set in the database in order to run on an Authenticated engine if you want non-read only access to the database with SQL Anywhere tools such as DBISQL and Sybase Central. The SQL Anywhere tool connections are self authenticating -- the database is not. If you are creating a database in an Authenticated environment, you will need to use authenticate.sql as documented to set the database_authentication option for the database.

Is it also correct that the Authentication violation happens sporadically?

(06 Aug '21, 03:32) Baron

For non-authenticated connections to authenticated databases there's the following detail:

An authenticated application must set the connection_authentication database option immediately after connecting.

The option must be set on every connection immediately after the connection is established. ODBC or JDBC applications query the database about its capabilities, and you may not have control over these actions. For this reason, every connection has a thirty second grace period before the restrictions apply. The grace period allows an application to authenticate regardless of which development tool is being used.

Might this "grace period" explain the "sporadic" issue? AFAIK, it should not apply to the builtin tools, as they are self-authenticating, but certainly to other connections unless/until those are authenticated.

The AUTHENTICATION_VIOLATION is not sporadic. It is reported at times when the authentication rules were violated. This means at any time that a write operation occurs on an connection that has not been authenticated. And it will always be reported on write operations that occur on an unauthenticated database.

My experience with sporadic cases generally are missed cases of setting the connection_authentication and often tied to the grace period that is provided.
