The JADE 2022 release meets tomorrow’s business demands.
In scenarios where it is desirable to deploy multiple secondary database servers for either load balancing or to increase data redundancy; today, these servers must connect directly to the primary database server with an associated increase in CPU, IO and network loads on the primary host.
The secondary relay proposal aims at reducing the load on the primary server and host in a multiple secondary environment and can also be used to reduce network traffic and use of valuable network resources around the primary site.
A secondary relay server is a secondary database node that connects to the primary and receives journal data from the primary database storing and forwarding journal data to downstream secondary databases.
Further secondary databases can then connect to and receive audit data from a relay server instead of connecting directly to the primary database server.
Relay servers would support either block mode transfer or journal file transfer modes to downstream secondary database servers. With journal file transfer mode, a journal would not be forwarded until the entire journal has been received. With block transfer mode individual audit blocks can be forwarded as soon as they are received.
