v Runtime connection failover
When one Oracle RAC node goes down, the active connections from
the node that went down will failover to the active node. When the
node that went down is up and running again, the connections are
not redistributed. You can redistribute the connection pools by setting
lifespan parameter to a value greater than 0, which ensures that
connection pools are terminated after the lifespan value is met and
load balancing occurs when new connections are established.
However, configuring a low value lifespan may lead to connections
being terminated quickly thereby losing the benefit of connection
pool.
To override all the Oracle pools lifespan to a value greater than 0, set
the following value in the customer_overrides.properties file:
jdbcService.<oraclepool>.
lifespan=180000
Visibility Event
Queues
You can increase the number of visibility queues and event input queue
capacity in customer_overrides.properties to ensure that adapters are
responsive.
To increase the default queue size and the thread counts, perform the
following tasks:
1. Set the following values in the ASI node and in
customer_overrides.properties.in file in containers:
dmivisibility.number_visibility_threads=6
dmivisibility.event_input_queue_capacity=3072
2. From the install_dir/install/bin (install_dir\install\bin for Windows)
directory, run (UNIX or Linux) setupfiles.sh or (Windows)
setupfiles.cmd.
3. Restart the ASI and container JVMs to apply the changes.
