Digipass Plug-In for SBR Administrator Reference ODBC Database
3.7.3 Connection Wait Time
When the SBR Plug-In already has the maximum number of connections open and a new
authentication request arrives, it will wait a configurable amount of time for a connection to
become available (unless the Enable Load Sharing option is used, see below). You may want
to reduce this waiting time, to reduce the impact of an overload of requests. Alternatively you
may want to increase the waiting time, to make it less likely that a request will be rejected due
to a temporary 'spike' of requests.
3.7.4 Idle Timeout
After a period of peak load, there may be a large number of connections open to the database.
The Idle Timeout setting can be used to configure how quickly the connections are closed
after being idle for a period of time. It may reduce the load on the database to close these
connections quickly. Alternatively, if the load is very irregular but is often high, you may prefer
to keep idle connections open for longer.
3.7.5 Enable Load Sharing
A simple form of load sharing can be implemented if you make a second database available to
the SBR Plug-In. In fact, any number of databases can be added to the list of data sources,
and the load can be shared across all of them.
If you have more than one database available and the Enable Load Sharing option is used,
the SBR Plug-In will open connections to the second database when it would exceed the
maximum number of connections it is allowed to have to the first database. Similarly, it will
open connections to the third database when it has reached the maximum for the second, and
so on. In general, connections to the first database will be used when available, in preference
to connections to any other database.
3.7.6 Reconnect Intervals
After the first data source has become unavailable, the SBR Plug-In will attempt at intervals to
reconnect, even if it has successfully failed over to a second data source. It will always use the
first data source in preference to the others.
The Min. Reconnect Interval and Max. Reconnect Interval settings control the minimum
and maximum intervals between retries respectively. The interval will start at the minimum
and increase in steps until the maximum is reached. After that, the interval will stay at the
maximum.
