disable second level cache

[Diana]

Hello!
We develop WPF and implemented data Access 2015.1.225.1 with cache level two, in some case we don't use information cache, we need data base information, configuring back-end over write SeconLevel property in false (SecondLevelCache.Enabled = false;)

However, data returned correspond with cache information.
How get data base information without set nocache value to entity in Cache Policy property (Cache Policy: NoCache)?

Thanks!

Hi Diana,

do you want to fetch the data fresh from the database, avoiding stale data in the cache?
Then you should either configure your database context instance so that no second level cache is used.
Or remove the content from the second level cache via context.LevelTwoCache.Evict() method.
Or is the issue that the data gets stale in the first place: Then you would need to configure second level cache synchronization. See

http://docs.telerik.com/data-access/developers-guide/crud-operations/working-with-second-level-cache/data-access-tasks-enable-second-level-cache-enable-code

for more information.

Alternatively you could open a second database connection with a different backend configuration and use this non-caching database for the code parts that need fresh information. However, I would not recommend this as it easily leads to confusion and the data is still stale in the caching connection potentially.

Hello Diana,

the context.LevelTwoCache.Evict() is the method to evict the second level cache and all content will be removed from it.
