Table 20. Connection Properties for the Sybase Driver (continued)
Property Description
ConnectionRetryCount
OPTIONAL
Sybase
The number of times the driver retries connections to a list of database
servers (primary and alternate) until a successful connection is
established. Valid values are 0 and any positive integer.
If set to 0, the driver does not retry a connection to the list of database
servers if a connection is not established on the driver’s first pass through
the list.
The default is 0.
For example, in the case where the following properties are specified:
AlternateServers=(server2:4100,server3:4100,server4:4100)
and
ConnectionRetryCount=1
if a connection is not successfully established on the driver’s first pass
through the list of database servers, the driver retries all the servers in the
list only once.
If an application sets a login timeout value, the login timeout takes
precedence over this property. For example, if the login timeout expires,
any connection attempts to alternate servers stop.
If the LoadBalancing property is set to true, the driver may sequence
through the list of servers (primary and alternate) in a different order each
time.
The ConnectionRetryDelay property specifies the wait interval, in
seconds, used between attempts.
See “Connection Retry” on page 133 for more information about
specifying connection information for primary and alternate servers.
