The DataNucleus page [1] says that the following persistence property is
required:
datanucleus.valuegeneration.increment.allocationSize
To specify this through Isis, add it into one of the Isis config files (eg
persistor_datanucleus.properties or if you prefer even isis.properties will
do) with the prefix isis.persistor.datanucleus.impl.; that is:
isis.persistor.datanucleus.impl.datanucleus.valuegeneration.increment.allocationSize
= ...
Isis will pass this property through directly (stripping off its prefix).
~~~
There's another example for a simpler property documented here on Isis'
website [2]

Thx,
It seems I have to set the key-cache-size in the jdo meta data. Where can
I put that value in Isis?

Hi Victor,
That's really a JDO/DataNucleus question; Isis just delegates to
DataNucleus to do its thang.
This page might help [1]. FWIW, we tend to use IDENTITY rather than
INCREMENT.
Cheers

Hi,
I’ve defined an incremental field in a domain object like this:
@Persistent(valueStrategy = IdGeneratorStrategy.INCREMENT)
private long invoicenumber;
This works fine, but there’s a small problem. Sometimes the NEXT_VALUE
skips a couple of numbers. Where did I go wrong?
Cheers,
Victor
