JIRA Load Balancing for Data Center

[Noby]

Our JDC 7.3.8 has 2 application servers along with shared drive and LB configurations to provide high availability . The app servers are connected to Exadata DB(active and standby mode) . At the moment the jdbc connection string is configured as <url>jdbc:oracle:thin:@//hostname:port/dbname</url>. This string doesn't provide HA from DB perspective. As well creating a DNS name for the primary and secondary DB is not a option we can't try.

So other than creating DNS name for DBs , does JIRA support below scan/HA JDBC url format so that JIRA DB connections can failover to secondary DB without application restart ? If yes, please give the correct syntax

jdbc:oracle:thin:(DESCRIPTION = (LOAD_BALANCE=ON) (ADDRESS = (PROTOCOL = tcp)(HOST = host1)(PORT = port1)) (ADDRESS = (PROTOCOL = tcp)(HOST = host2)(PORT = port2)) (CONNECT_DATA = (SERVER=dedicated) (SERVICE_NAME=service_name)))
