Subject [jira] Commented: (JDO-678) Ability to set properties on PersistenceManager
Date Tue, 08 Mar 2011 14:26:59 GMT

    [ https://issues.apache.org/jira/browse/JDO-678?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13003963#comment-13003963
] 

Andy Jefferson commented on JDO-678:
------------------------------------

Well a Properties ought to have String values only (even though it actually implements Map<Object,Object>).
A vendor may allow non-String values (setProperty(String, Object)). For example, the PMF has
a setting javax.jdo.option.DatastoreReadTimeoutMillis which is an integer, and the PM could
allow setting of the same thing taking in an Integer. Vendor specifics may also be non-String.

> It would be desirable to be able to set properties on the PersistenceManager, so as to
be able to configure/change behaviour for a PM. Currently the PM is generated with particular
configuration (from the PMF) and allows specific options to be set. But what about vendor
extensions ? Having a general setProperty/getProperty/getSupportedProperties would be useful,
and could also encompass the existing detachAllOnCommit, IgnoreCache, etc settings.
