6 To enable the external database, from the Oracle Server section of the
server.properties file, uncomment each line by removing the pound signs
(#) for each variable and configure according to your customized needs:
#### Oracle Server #####
DBDriver=oracle.jdbc.driver.OracleDriver
DBURL=jdbc:oracle:thin:@ <serverName> : <port_number> : <dbName>
DBLong=NUMBER
DBEmbeddedQuote=''
DBFile=
DBUserName= <db_username>
DBPassword= <db_password>
Table 22 lists the fields in the Oracle Server section of the server.properties
file and gives descriptions and default values.
When you connect to an Oracle cluster, you need to specify a different
connection string telling the JDBC connector that it has a choice of
two connections — in this example
<serverName1>
or
<serverName2>
.
Note that you can specify different port numbers too.
DBURL=jdbc:oracle:thin:@(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=
(PROTOCOL=TCP)(HOST=<serverName1>)(PORT=<port_number1>))(ADD
RESS=(PROTOCOL=TCP)(HOST=<serverName2>)(PORT=<port_number2>)
)(FAILOVER=on)(LOAD_BALANCE=off))(CONNECT_DATA=(SERVER=DEDIC
ATED)(SERVICE_NAME=dbase)))

Field Description
