Oracle Driver Connection Failover Properties<br />
Oracle<br />
Table 15 summarizes the connection properties that control how connection failover<br />
works with the Oracle driver. See “Oracle Driver Connection Properties” on page 175 for<br />
details about configuring each property.<br />
Table 15. Connection Failover Properties for the Oracle Driver<br />
Property Description<br />
AlternateServers List of alternate database servers. An IP address or server name identifying each<br />
server is required. Port number <strong>and</strong> the ServiceName or SID connection properties<br />
are optional. If the port number is unspecified, the port specified for the primary<br />
server is used. If a port number is not specified for the primary server, the default<br />
port number of 1521 is used.<br />
ConnectionRetryCount Number of times the driver retries the list of database servers (primary <strong>and</strong> alternate)<br />
until a successful connection is established. The default is 0 (connection retry is not<br />
used).<br />
ConnectionRetryDelay Wait interval, in seconds, used between attempts to connect to a list of database<br />
servers (primary <strong>and</strong> alternate) when the ConnectionRetryCount property is set to a<br />
positive integer. The default is 3.<br />
LoadBalancing Sets whether the driver will use client load balancing in its attempts to connect to the<br />
list of database servers (primary <strong>and</strong> alternate). If client load balancing is enabled,<br />
the driver uses a r<strong>and</strong>om pattern instead of a sequential pattern in its attempts to<br />
connect. The default is false (client load balancing is disabled).<br />
ServiceName The database service name that specifies the database used for the connection. This<br />
property is mutually exclusive with the SID property.<br />
SID The Oracle System Identifier that refers to the instance of the Oracle database<br />
running on the server. The default is ORCL. This property is mutually exclusive with<br />
the ServiceName property.<br />
See “Client Load Balancing” on page 131 <strong>and</strong> “Connection Failover” on page 132 for<br />
overviews of these features.<br />
