If the server

restrictAccess

property is false or not specified or if no

allowDatabase

subsection is specified for the server then no database restrictions will be applied.

Example 1

For example given the above server description of a server running on the node bravo :

Connection conn = DriverManager.getConnection(

"jdbc:rdbThin://bravo:1701/mf_pers",user, pass);

will be allowed.

Example 2

Connection conn = DriverManager.getConnection(

"jdbc:rdbThin://bravo:1701/MF_Pers",user, pass);

will be allowed because character case in the database specification is not significant.

Example 3

Connection conn = DriverManager.getConnection(

"jdbc:rdbThin://bravo:1701/disk1:[databases]customers",user, pass);

will be allowed.

Example 4

Connection conn = DriverManager.getConnection(

"jdbc:rdbThin://bravo:1701/disk1:[databases]customers.rdb",user,

pass);

will NOT be allowed due to the extra

".rdb"

.

Example 5

Connection conn = DriverManager.getConnection(

"jdbc:rdbThin://bravo:1701/cust ",user, pass);

will NOT be allowed even though cust may be a logical name that translates to

disk1:[databases]customers

8.16.2 Restricting User Access

When using a thin server, Rdb authorization checking is carried out during the connection to

the database. Rdb will check the username and password provided to determine the

authorization access for the given user.

In addition you may further restrict which users may use the server by setting the

restrictAccess

property for the server in the configuration file and then providing a list of

usernames that will be allowed using

allowUser

subsections.
