Re: [castor-dev] object being incorrectly read from cache

[Colin Canfield]

Title: Message

Yep; unforunately in my app I would love the cache to be there for long transaction checking... I solved it by switching off the cache and manually checking dirty fields on return and hand coding the two phase transactions...

All that would be needed to solve it would be someway to force a particular query to reload the cache; or possibly even clear the cache for a particular object type at certain times ? 

Thanks, Colin

However, that can lead to "interesting" transaction and locking issues when trying to do an update.

The purpose of a cache is exactly what you describe: avoid having to hit the database every time.  If you absolutely need the latest data from the DB (and there is a possiblity users will be directly updating the DB) then turn caching off.

Subject: [castor-dev] object being incorrectly read from cache

I am reading an object, processing it setting a value and storing it. When I edit the underlying database (in a seperate application not using castor); and then run the query again it returns me the original object from the castor cache rather than the new database entry...

is there anyway to clear the cache ? or force a reload into the cache ?

this object is implements long transactions , is that perhaps the problem ?

Thanks, Colin
