(C1) Query is found to exist; result set is retrieved from the Cache Manager

(C2) Result is returned to the querying application

Flow Process – Query In Cache

7

Flow Process – Query Not In Cache & Not Update

(Q1) Query is processed on target database

(Q2) Result set is returned

(Q3) If repetitive query, result set is saved in RAM memory of the Cache Manager to be accessed upon the next instance of the identical query

8

(U1) Request is parsed and all results stored in Cache that have any connection to the affected database tables are evicted

(U2) Request is sent to target SQL Server database and executed

(U3) Result set is sent back to the querying application

Write Request (update, insert, delete)

Ensuring High Availability

10

(A1) Query is routed to Active SafePeak server, using MS NLB (VIP) technology (SafePeak Enterprise version), and then thru Network-Proxy SW to SafePeak (A2).

(A3, A4) In the rare event of software failure, processing is automatically redirected to 2nd SafePeak (A3 - optional)or directly to the database (A4).

(P1) If a HW error occurs due to a malfunctioning server, processing is automatically shifted into passive SafePeak, ensuring that the loss of the server will not impact continuous processing.

(P2) Query is then routed to 2nd SafePeak.

(P3) If error occurs, processing is redirected to the SQL Server database
