First Connection Attributes

TimesTen sets first connection attributes when a database created by the instance administrator is loaded into memory and persist for the first connection and all subsequent connections until the last connection to this database is closed.

You can modify first connection attributes only when the TimesTen database is unloaded. Then the instance administrator reconnects with new values for the first connection attributes.

If you try to connect to the database using attributes that are different from the first connection attribute settings, the new connection can be rejected or the attribute value can be ignored. However, for example, if existing connections have a LogFileSize of one size and a new connection specifies a LogFileSize of another size, TimesTen ignores the new value and returns a warning.

Only the instance administrator can change a first connection attribute to a value other than the one currently in effect. To change the value of a first connection attribute, you must first shut down the database and then connect with ADMIN privileges. No privileges are required to change AutoCreate and ForceConnect.

The first connection attributes are described in detail next.
