Oracle Audio Technologies B31679-01 Instance access, Cache Connect, Replication, Client/Server

Cache Connect

For Cache Connect, the TimesTen internal user must match the Oracle user. External Client/Server users must match the Oracle user. If you are using the Cache Connect Administrator interface, the user must be an internal TimesTen user.

Replication

If Access Control is enabled, replication daemon administration and replication schema changes are restricted to users having the ADMIN privilege. See “Privileges” on page 13.

Changes are applied to a replicated subscriber data store regardless of the settings or presence of Access Control on the subscriber.

Instance user configuration commands are not replicated.

Client/Server

If a TimesTen client connects to a Timesten server, and the server side data store has Access Control enabled, the server’s Authenticate attribute must be enabled.

To use Access Control with Client/Server applications, when the user is identified externally, the Client and the Server processes must be on the same machine. When Access Control is enabled, remote Client/Server access is only supported with TimesTen internal users.

TimesTen ignores the values of UID, PWD and PWDCrypt if specified in the Server DSN. These are client-side only attributes. The user name and password must be explicitly declared on the Client side.

When Access Control is enable, if PWD or PWDCrypt is specified in Client/Server applications, TimesTen assumes that the user is internally identified, otherwise TimesTen assumes that the user is externally identified and authenticated by the operating system.
