Hello,
I'm trying to get read-ahead working with the 3.0 release. Here's what my
jbosscmp-jdbc.xml looks like.
<jbosscmp-jdbc>
<defaults>
<datasource>java:/OracleDS</datasource>
<datasource-mapping>Oracle8</datasource-mapping>
<read-ahead>
<strategy>on-load</strategy>
<page-size>1000</page-size>
<eager-load-group>*</eager-load-group>
</read-ahead>
<list-cache-max>1000</list-cache-max>
</defaults>
<enterprise-beans>........
However, I still get N+1 queries run the the CMP engine so the performance
of the first read is very slow.
I'm using Commit option A for these beans, could that be creating the problem?
I got this config from the standardjbosscmp-jdbc.xml file. I've checked the
CMP docs I purchased for 3.0 CMP
but they are out of date (I'm also chasing Flashline to get an up to date copy)
Can anyone tell me how to make this work? I can't use jboss CMP until I
solve this problem and I really want to avoid
BMP.
Also, if anyone can tell me where I might find docs on replacing the
pluggable load strategy, I'd really like to test this out.
Steve
