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