Default caching strategy for CMP

[kgodbole]

Hi
I am new to CMP and I am trying to use JBoss 3.2.1 with M$ SQL server. I wanted to know if there is any default strategy used for caching query results in CM Persistance.

The documentation mentions three read-ahead strategies :
on-load
on-find
none.

But does not mention which is the default.

Any help will be greatly appreciated.
Thanks

Hi,

on-load and on-find is connected with finders not caching.

As for caching, you should set 'commit-option'. There are four commit options available: A, B, C, D. Please refer to jboss_3_2.dtd in your jboss/docs/dtd for details about them.

IIRC on-load is the default, can't remember the page size though

Hi all
Thank you all for your responses. I have found the default settings. They are given in a file $JBOSS_HOME/server/default/conf/standardjbosscmp-jdbc.xml

The default read-ahead settings are as follows:
<read-ahead>
on-load
<page-size>1000</page-size>
<eager-load-group>*</eager-load-group>
</read-ahead>


Also the default commit options for various container configurations are given in a file called $JBOSS_HOME/server/default/conf/standardjboss.xml

The commit settings for "Standard CMP 2.x EntityBean" configuration are :
<commit-option>B</commit-option>


Hope this helps someone. :-)
