  The 'timestamps',Is that used to configure the cluster?if it's not,what can I do use 'timestamps'?thanks~~~ 

[nadirx]

All of the caches defined in the default AS7 configuration are either for clustering (Servlet Sessions, SFSB) or for Hibernate caching (as in this case). The timestamps cache in particular is used to store timestamps of when a table was last written to. It has nothing to do with clustering.

thanks Tristan!  I want to optimize the cache,I don't know how to set the 'timestamps' to get more performance,i didn't find how to set it in document,thanks~~~

[galder.zamarreno]

Why do you wanna change the config of timestamps cache? What makes you think that the performance issues you're having are rooted on that cache?

[alvinz]

Thanks Galder! How to say...you mean if I optimize cache I can ignore configuration of timestamps?thanks~~~

[galder.zamarreno]

Those timestamps are used to manage the query cache, so it's only relevant if your 2LC has query cache enabled.

[alvinz]

Thanks Galder! yes,2LC has query cache enabled,could you give me more info about timestamps? URL and Doc both ok,thanks~~~

[galder.zamarreno]

The role of the different caches is nicely explained in http://docs.jboss.org/jbossclustering/hibernate-caching/3.5/en-US/html/concepts.html#concepts-data-types

[alvinz]

Thank you very mush  Galder!

[alvinz]

last one question,I want to know hot to config two options,URL and Doc both ok,thanks~~~

<local-cache name="timestamps">

     option 1 <transaction mode="NONE"/>

     option 2 <eviction strategy="NONE"/>

</local-cache>

[alvinz]

I found a doc,but there is no how to config timestamps........

I don't see a reason for you to touch the default timestamps configuration. Leave it as it is - IOW, no transactions, no eviction.
