  Oracle Tips by Burleson

Oracle 10g Improved Connection Manager Access Rules

  • dst – This parameter is used to specify the destination host name or IP address of the database server. The IP address is allowed to be a generalized subnet, such as 152.10.10.62/24.
     

  • srv  – This parameter specifies the service name of the Oracle 10g, Oracle9i, or Oracle8i database (as specified  in the service_name parameter in the database initialization parameter file).
     

  • act  – This parameter specifies whether to accept, reject, or drop incoming requests, based on the preceding three parameters.

In the next example, we use the act procedure to set the entry for the rule_set parameter in our cman.ora. We specify that the client computer tuscga1-pc is denied access to the database service test.us.rampant.com, and the client whose address is 90.10.100.2 is granted access to the service aultdb1 on the host with address 90.10.100.3.

(RULE_LIST=(
(RULE=(SRC=tuscga1-pc)(DST=test-server)(SRV=test.us.rampant.com(ACT=reject))
(RULE=(SRC=90.10.100.2)(DST=90.10.100.3)(SRV=aultdb1)(ACT=accept))))

As with any of the other new features described in this publication, you should read the appropriate Oracle 10g manuals before attempting to set and use the new features. Let’s move on to the Automated Shared Server Configuration feature.
