<div class="block">Sequence-based primary key generator implementation for Oracle. Uses Oracle
sequences to generate primary key values. This approach is at least 50%
faster when tested with Oracle compared to the lookup table approach.
<p>
When using Cayenne key caching mechanism, make sure that sequences in the
database have "INCREMENT BY" greater or equal to OraclePkGenerator
"pkCacheSize" property value. If this is not the case, you will need to
adjust PkGenerator value accordingly. For example when sequence is
incremented by 1 each time, use the following code:
</p>

dataNode.getAdapter().getPkGenerator().setPkCacheSize(1);
