During a Guardium deployment planning meeting, a database administrator indicated that the mission critical databases were clustered.
How should the Guardium administrator handle S-TAP installation and configuration with respect to clustered databases?
A. Install S-TAP agents on all active nodes. Set ALL_CAN_CONTROL=1 to failover the S-TAP process to the passive nodes when a database failover occurs.
B. Install S-TAP agents on all active nodes. Set WAIT_FOR_DB_EXEC=-1 to set the agent process to failover to the passive node when a database failover occurs.
C. Install S-TAP agents on all active and passive nodes. Set ALL_CAN_CONTROL=0 to disable all passive nodes until a database failover occurs.
D. Install S-TAP agents on all active and passive nodes: Set WAIT_FOR_DB_EXEC>0 on all nodes to start S-TAP processes without waiting for a correct DB home.
Correct Answer: A
Explanation/Reference:
To properly support load balancing, the Guardium S-TAP agents must be configured properly.
Add, uncomment, or modify the settings on your S-TAP Configuration to look like the following examples.
See the Guardium product documentation on how and where to adjust the S-TAP configuration file, as well as for updated guidance from IBM.
* Sqlguard_ip = <Your BIG-IP Virtual Server IP address/hostname>
For example: Sqlguard_ip = 192.0.2.123
* Participate_load_balancing = 3
* All_can_control = 1
Sqlguard_ip is the address you will define on BIG-IP LTM during the Virtual Server configuration.
Participate in Load balancing allows the S-TAP to send session information on every failover to the appliance.
All Can Control allows the S-TAP to be able to edit S-TAP configurations through GUI.
Note: all_can_control
. 0=S-TAP can be controlled only from the primary Guardium system. 1=S-TAP can be controlled from any Guardium system.
