What am I doing wrong ? I've tried to tune my jboss app setting read-ahead
options but this is what happening :
1) configuration is read and is syntactical correct as if I deliberately
break it (for example inserting wrong values for read-ahead strategy),
deployment will not work and an error is signaled.
2) when a find method is invoked I see from the trace that the default
read-ahed policy is used instead of the one I've configured
Is there something I miss ?
an excerpt from my jbossjdbc-cmp.xml :
<entity>
<ejb-name>Message</ejb-name>
<cmp-field>
<field-name>message</field-name>
<column-name>msg</column-name>
<jdbc-type>LONGVARCHAR</jdbc-type>
<sql-type>LONG</sql-type>
</cmp-field>
<eager-load-group>msgDescr</eager-load-group>
<load-groups>
<load-group>
<description>Descrizione del
messaggio</description>
<load-group-name>msgDescr</load-group-name>
<field-name>submitDate</field-name>
<field-name>type</field-name>
<field-name>needServerProcessing</field-name>
</load-group>
</load-groups>
<read-ahead>
<strategy>on-load</strategy>
<page-size>1</page-size>
<eager-load-group>msgDescr</eager-load-group>
</read-ahead>
</entity>
The trace :
2002-07-09 19:33:20,812 TRACE
[org.jboss.ejb.plugins.cmp.jdbc.JDBCLoadEntityCommand.Message] Eager-load for
entity: readahead
