Set Cache Administration User Name and Password
The cache administration user name and password must be set only once in a TimesTen database. However, they must be changed if the TimesTen database is destroyed and recreated or if the cache administration user name is dropped and recreated in the Oracle database.
The cache administration user name and password cannot be changed if the cache agent is running on the TimesTen database or there are cache groups in the database. The cache groups must be dropped before you can change the cache administration user name and password. You must also stop the cache agent before you change the cache administration user name and password, and then restart the cache agent after the user name and password have been changed.
See Registering the Cache Administration User Name and Password in the Oracle TimesTen In-Memory Database Cache Guide.
